    Facsimile with beep control.
    The present invention relates to a facsimile, and more particularly, to a method and apparatus for selectively listening to a beep by controlling various beeps generated during transmission and reception of fax data in a facsimile using an optical sensing element.
    In general, a fax machine includes a scanner capable of reading a document therein, a printer capable of outputting data in text form, and a communication means such as a telephone line for transmitting and receiving data with a remote party. Refers to an integrated device that can be interchanged.
    Such a facsimile has a function of notifying a user of transmission and reception of fax data by generating a beep sound when sending and receiving fax data. However, in the conventional facsimile, there is no way to prevent the facsimile's beep from being automatically heard when the user does not want to be interrupted by non-work time or the facsimile's beep at bedtime. There is only a function to turn on / off, there is no device to directly control the output of the speaker according to the external conditions, and to control the beep according to the pre-input program.
    A similar function is to select and input the desired time zone. This method cannot detect and control the time zone automatically. If the user continues to work after the set time, readjust the time zone. There is a disadvantage in that the facsimile which can perform such a function is possible only in an expensive model to which a liquid crystal display panel or the like is attached.
    Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to detect a condition that the fax does not want to automatically hear a beep, and to block a beep generated when fax data is transmitted and received. It also allows the addition of ringer control in low cost facsimile machines.
    1 is a circuit diagram showing a circuit configuration for outputting a fax signal sound according to the present invention;
    2 is a flow chart for controlling the operation of the speaker according to the present invention.

    50: speaker 60: beep input unit
    70: control unit
    In order to achieve the above object, the present invention includes a light sensing element for detecting light and converting it into an electrical signal, and a control unit for performing a predetermined process for operating the speaker using the electrical signal input from the light sensing element. Characterized in that.
    Preferably, the photosensitive device is characterized in that the phototransistor (Phototransistor) which is a photoelectric device that changes the current in accordance with the change of light.
    Preferably, the controller is a control signal unit for transmitting a control signal to the switch using the electrical signal input from the optical sensing element, and a switch for turning on / off the speaker using the control signal transmitted from the control signal unit Characterized in that it comprises a.
    Hereinafter, the objects, features, and advantages of the present invention described above will be described in detail with reference to preferred embodiments of the present invention shown in the accompanying drawings.
    1 is a circuit diagram showing a circuit configuration for outputting a fax signal sound to a speaker according to the present invention.
    As shown, in order to implement control of automatic transmission sound, an optical sensing element 10 is added to a circuit so that an electrical signal is transmitted to the control signal unit 30 according to the presence or absence of light, and the control is performed by the electrical signal. The signal unit 30 is configured to transmit a control signal to the switch 40 to turn on / off the operation of the speaker 50.
    Hereinafter, a facsimile equipped with a beep control device of the present invention will be described in detail with reference to FIGS. 1 and 2.
    First, when the signal blocking function is set by the user (S100), when the light sensing unit 20 of the photosensitive device 10 detects light and the photosensitive device is turned on, the first pull up resistor is used. The input current value maintained at 5V input to the control signal unit 30 becomes 0V. Therefore, when the values are different by comparing the input current value with the current value 5V input to the control signal unit 30 through the pull-up resistor (S110), the control signal unit 30 is switched on. By transmitting a control signal (S120), the speaker 50 maintains an on state (S130) for generating a beep to perform a facsimile transmission and reception operation.
    In addition, the input current value and the current value (5V) input to the control signal unit 30 through the pull-up resistor (S110) if the value is the same, the light receiving unit 20 does not detect the light to the light Since the input current value input to the control signal part 30 through the pull-up resistor is maintained at 5V while the sensing element 10 is off, the control signal part 30 is applied to the switch part 40. Transmitting a switch-off control signal (S140) to maintain the off state (S150) in which the speaker 50 does not generate a beep to perform a fax transmission and reception operation.
    Although a preferred embodiment of the present invention has been described in detail above, those skilled in the art to which the present invention pertains may make various changes without departing from the spirit and scope of the invention as defined in the appended claims. It will be appreciated that modifications or variations may be made. Therefore, changes in the future embodiments of the present invention will not depart from the technology of the present invention.
    As described above, according to the present invention, by selecting a function to automatically control the beeps of the facsimile, it is possible to block unnecessary facsimile transmission and reception tones that occur when the user turns on the facsimile at night or at bedtime, and it is also simple and inexpensive. The low cost facsimile can also be used to add tones.
