    Memory drive with multi-connector and control method thereof {MEMORYDRIVE WITH MULTI CONNECTER AND METHOD OF CONTROLLING THE SAME}
    [15] BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a memory drive having a multi-connector and a control method thereof. More specifically, the present invention relates to a multi-connector which improves the compatibility of a memory drive by providing a plurality of different types of connectors in a memory drive mounted on an electronic device. It relates to a memory drive having a.
    [16] Storage devices, commonly referred to as memory drives or memory disks, are in the spotlight as new storage interfaces that can replace existing auxiliary storage devices.
    [17] The memory drive can store relatively large amounts of data from 8MB to 256MB and is easy to update. In addition, since there is no need for a separate drive, there is an advantage in that data can be stored in an electronic device such as a digital camera, PDA, mobile phone, as well as a computer.
    [18] Most of these memory drives support a USB interface. Here, the USB interface is a unified standard of the data interface specification developed to easily connect peripheral devices such as a printer, a mouse, and a keyboard. The USB port is divided into A type USB port, B type USB port, 5 pin mini B type USB port, and 4 pin mini B type USB port according to the location, number and size of the pins.
    [19] 5 shows an A-type USB port and a mini-B type USB port. As shown in the figure, a typical USB port consists of 4 pins of 5V power supply pin, + data, -data, and GND. Here, the A type USB port is a USB port provided in the computer body, and the mini B type USB port is a USB port provided in a portable device such as a digital camera. They differ only in the size of the ports, and the types of signals input and output through each pin are the same. Accordingly, the computer main body adopts an A type USB port, but in the case of a portable electronic device that is subject to space limitations, a mini B type USB port having a smaller size than the A type USB port is adopted.
    [20] On the other hand, the memory drive has an A-type USB connector so that it can be attached to an A-type USB port provided in the computer body. Therefore, when storing data from a portable electronic device such as a digital camera, it cannot be directly connected to the mini-B type USB port of the portable electronic device. Accordingly, when a memory drive is to be connected to the portable electronic device, the A type USB port for connecting the memory drive is provided on one side and the mini B type connector for connecting the portable electronic device is connected on the other side using a cable. To make it work.
    [21] As described above, when the connector provided in the memory drive is different from the port provided in the electronic device, it is inconvenient to use a separate cable.
    [22] Accordingly, an object of the present invention is to provide a memory drive that can be easily connected to various electronic devices.

Achieved by a memory drive having:
    [24] The apparatus may further include a plurality of switches installed to correspond to the plurality of connectors to control the signals input and output through the connectors, and wherein the controller is configured to simultaneously connect two or more connectors among the plurality of connectors. It is possible to control each switch to block input and output of data through a connector other than one of the predetermined connectors, so that only the data input through the predetermined connector can be processed.
    [25] Meanwhile, according to another aspect of the present invention, there is provided a control method of a portable memory drive, comprising the steps of: preparing a plurality of connectors of different types in advance for data transmission and reception with an electronic device; Determining whether two or more of the plurality of connectors are simultaneously connected when the power is applied; If it is determined that two or more connectors of the plurality of connectors are connected at the same time, blocking input / output of data through a connector other than one of the predetermined connectors; It is also achieved by a control method of a memory drive having a multi-connector, characterized in that for processing the data input and output through any one of the predetermined connector.
    [26] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
    [27] 1 is a control block diagram of a memory drive according to the present invention. As shown in the figure, the memory drive is installed so as to correspond to each connector and a first connector 1 for connecting to an electronic device, a second connector 3 of a different type from the first connector 1, and the like. And a first switch 10 and a second switch 12 for intermitting input and output of signals through the connector, a memory 7 storing data from the outside, and data input through the respective connectors. ) And a controller 5 for providing data stored in the memory 7 to an external device through a connector and controlling a short circuit of the switch.
    [28] The first connector (1) and the second connector (3) are for connecting to the ports provided in the electronic device, A type USB connector supporting USB interface, B type USB connector, 5 pin mini B type USB connector, 4 pin Mini B type USB connector can be used. In addition, the connector of the memory drive may employ a connector for other interfaces that can be applied to the memory drive, such as an IEEE 1394 connector that supports the IEEE 1394 interface in addition to the USB interface. Here, the names of the first connector 1 and the second connector 3 mean that they are different kinds of connectors. Therefore, the user can directly select the connector corresponding to the port provided in the electronic device and directly mount the memory drive to the port of the electronic device.
    [29] The first switch 10 and the second switch 12 control the input / output of signals through the first connector 1 and the second connector 3, respectively, under the control of the controller 5.
    [30] Here, the controller 5 stores the data input through the connector in the memory 7 or provides the data to the electronic device connected to the connector. In addition, the control unit 5 controls the first switch 10 and the second switch 12 to control the input / output of signals through each connector, so that when each connector is connected to an electronic device at the same time, through either connector Only input signals are processed.
    [31] For example, when the first connector 1 is designated as a priority, when it is determined that both the first connector 1 and the second connector 3 are connected, the control unit 5 advances the second connector 3 in advance. The second switch 12 connected to the) is turned off to block the signal, and processes only the signal input through the first connector 1. Here, the connector having priority may be preset in the design process.
    [32] With this configuration, the user can connect the connector corresponding to the port provided in the electronic device to the port of the electronic device so that the data stored in the electronic device can be stored in the memory 7, even when each connector is connected at the same time. The memory drive can be operated normally.
    [33] In addition, although the above description demonstrates the case where two different connectors are employ | adopted, it is also possible to mount two or more different types of connectors. In this case, a switch corresponding to each connector will be further added, and the controller 5 should be designed to perform a control function according to the interface applied to each connector.
    [34] In the case of a memory drive employing a plurality of connectors, the control flow of the control unit 5 is as shown in FIG. When the memory drive is mounted on the electronic device and power is applied (S10), the controller 5 determines whether a plurality of connectors are connected at the same time (S12). As a result of determination, when only one connector is connected, the controller 5 processes data input through the connected connector (S14). On the other hand, if it is determined that two or more connectors are connected to the electronic device, the control unit 5 controls all switches corresponding to the connector other than the designated connector to be turned off according to a predetermined rank, and inputs through the designated connector. The data is processed (S16).
    [35] 3 is a perspective view of a memory drive 20 according to an embodiment of the present invention. As shown in the figure, the memory drive 20 according to the present embodiment is provided with an A-type USB connector 31 and a mini-B type USB connector 33 at both ends of the bar-shaped main body, respectively.
    [36] The bar-shaped main body is provided with an LED 28 and a write protection switch 26 indicating whether the memory drive 20 is operated.
    [37] The A type USB connector 31 provided at one end of the main body is for connecting to a USB port provided at the computer body, and the mini B type USB connector 33 provided at the other end is a USB port having a smaller size than the A type USB port. It is to connect to.
    [38] Accordingly, when the data stored in the computer is to be backed up to the memory drive 20, the memory drive 20 may be mounted on the computer main body using the A type USB connector 31. In addition, when backing up data of a portable electronic device such as a digital camera, the memory drive 20 may be directly mounted on the portable electronic device using the mini-B type USB connector 33.
    [39] As such, the internal control block diagram of the memory drive 20 is as shown in FIG. As shown in FIG. 4, the memory drive 20 according to the present invention includes a memory 37 in which data is stored, an A type USB connector 31 and a mini B type USB connector 33, and a mini B type. Switching signal for applying a control signal to each switch in accordance with the first data control switch 40 and the second data control switch 42 to control the data signal of the USB connector 33 and the power input signal from the power line A generator 44, a reverse voltage prevention unit 39 interposed on a power input line of each connector to prevent reverse voltage, and a control function such as storing and reading data in accordance with a signal input through the connector. USB control unit 35 is included.
    [40] The A type USB connector 31 and the mini B type USB connector 33 are connectors supporting a USB interface, and differ only in the size of the connector shown in appearance, and each has a pin having the same function. The A type USB connector 31 and the mini B type USB connector 33 include four pins. Of the 4 pins, pin 1 receives 5V power from the electronic device, pins 2 and 3 receive the -data and + data signals, and pin 4 is used for GND.
    [41] The reverse voltage prevention part 39 has a 5V power input through the mini-B type USB connector 33 when both the A-type USB connector 31 and the mini-B type USB connector 33 are connected to an electronic device. It prevents backflow to the A type USB connector (31).
    [42] The first data interrupt switch 40 and the second data interrupt switch 42 intercept data signals input from pins 2 and 3 of the mini-B type USB connector 33. Here, pins 2 and 3 of the mini-B type USB connector 33 are pins to which a -data signal and a + data signal are input. Therefore, when each switch is turned on, the data input through the mini-B type USB connector 33 is normally transmitted to the USB controller 35. However, when each switch is turned off, data is not transmitted even when the memory drive 20 is connected to the electronic device through the mini-B type USB connector 33.
    [43] The switching signal generator 44 is installed on a power line branched from a 5V power line of the A type USB connector 31 and the mini B type USB connector 33, and when 5V power is input from both connectors, A switching signal is applied to the switch 10 and the second switch 12 so that the switch is turned off. Accordingly, when the A-type USB connector 31 and the mini-B type USB connector 33 are connected at the same time, the data signal input through the mini-B type USB connector 33 is cut off, and the A type USB connector 31 is disconnected. Only the data signal input through the transfer to the USB control unit 35.
    [44] The USB controller 35 stores data input through each connector in the memory 37 or provides data stored in the memory 37 to the outside through the connector. The USB controller 35 may perform not only data input / output management but also control functions such as data compression, memory allocation, message exchange, work time planning, and the like.
    [45] By such a configuration, the user can directly install and use the memory drive 20 without a separate cable in the portable electronic device in which the mini-B type USB port is installed, as well as the computer body in which the A type USB port is installed.
    [46] In addition, when both the A type USB connector 31 and the mini B type USB connector 33 are connected to the electronic device, the data signal input through the mini B type USB connector 33 is blocked, and the A type USB connector Only the data signal input through the connector 31 can be processed. The connector to be used effectively when the connectors are connected simultaneously can be specified differently according to the design method.
    [47] In the above-described embodiment, the memory drive is provided with two connectors, but the number of connectors that the memory drive according to the present invention can include is not limited, and the type of connector is also a B type USB connector, 5 Not only can it be replaced with a pin mini-B type USB connector, but also a connector adopted for the IEEE1394 interface instead of the USB interface.
    [48] In addition, in the above-described embodiment, the switching control signal for intermitting data is described as being applied from the switching signal generator. However, by changing the circuit design of the control program of the conventional USB controller, the switching control signal is applied to the USB controller. It is of course also possible to apply.
    [49] As described above, the present invention is provided with a plurality of different types of connectors in the memory drive, so that the memory drive can be directly attached to the various ports provided in the electronic device without any additional means such as cables. As a result, the memory drive can be easily mounted and compatibility can be improved.
    [50] Further, by further providing a switch for intermitting signals from each connector, even when a plurality of connectors are connected at the same time, only the data input through a predetermined connector can be processed, so that the memory drive can operate normally. .
    [51] As described above, according to the present invention, a memory drive that can be easily connected to various electronic devices is provided.
