    Field of the invention
    The present invention relates to an ink cartridge for a pen and a pen with such an ink cartridge.
    Description of the Related Art
    [0002] The tactile devices are used in various fields of application in which object presence detections are involved, such as, but not limited to, touch pads, touch panels, touch screens or capacitive projective displays. . The tactile devices detect passive objects touching the touch device and can determine the contact position. This allows for example a user control. Pens are often used as passive objects. In order to improve position detection, the active pens apply an electrical signal to the tip of the pen for capacitive, inductive or electromagnetic coupling with the touch device.
    To write or draw on paper or any other base material, another type of pen is needed, which transfers the ink to the base material. Today two types of pen are needed to interact, that is to say write or draw, on a touch sensor and interact on paper.
    [0004] EP 1 370 425 or US 6 454 482 discloses a pen for use on a tactile device and on paper. The pen includes a tip configured for use on a touch screen, and does not transfer ink from the ink tank to the tip. A printhead is disposed adjacent the tip to electronically transfer ink from the ink reservoir to the paper if the pen is not used on a touch screen. However, the experience of writing such a pen is more that of an aerosol can than that of a conventional pen.
    [0005] US 2003 118 391 discloses a writing pen with a ball point for transferring ink from an ink reservoir to a paper. The rolling of the ball can be avoided by a piezoelectric element or by an electromagnet, in case of detection of a proximity between the writing pen and a touch sensor. This prevents the transfer of ink from the ink tank to the touch screen. However, heavy pressure or impact on the ball could damage the solenoid or piezo element and damage the ink transfer interruption mechanism.
    Brief summary of the invention
    It is therefore an objective to provide an ink cartridge configured for a pen that is suitable for alternating use between an ink mode and an electronic mode, which allows a conventional writing experience in ink mode. and having a robust manner for controlling / stopping the transfer of ink from the ink tank to the paper for the electronic mode.
    According to the invention, these objectives are achieved by means of an ink cartridge according to claim 1 and a pen with such a cartridge.
    The use of an electronic device for creating an ink jet from the ink tank on the surface of the ball of the tip of the cartridge makes available the electronic device used for the control of the transfer of the ink at a safe distance from the ball. As a result, impacts and pressure shocks on the ball are not transferred to the electronic device.
    The dependent claims refer to more advantageous embodiments of the invention.
    The use of a semiconductor device and / or a device with microelectromechanical systems (MEMS) is an advantageous embodiment of an ink jet in an ink cartridge for a pen.
    If the material of the tip and / or the ball is made by an electrical conductor, such as a metal, the tip and / or the ball may be used also for the application of an electrical signal for the capacitive, inductive or electromagnetic coupling with a position sensor.
    Brief Description of the drawings
    The invention will be better understood from the description of an embodiment given by way of example and illustrated by the figures, in which:<tb> Fig. 1 <SEP> shows a first section of an embodiment of an ink cartridge;<tb> fig. 2 <SEP> shows a second section of the embodiment of the ink cartridge of FIG. 1; and<tb> fig. 3 <SEP> shows an embodiment of a pen comprising an ink cartridge.
    Detailed Description of the Possible Embodiments of the Invention
    Figs. 1 and 2 show an embodiment of an ink cartridge 1. FIG. 1 shows a sectional view along a longitudinal axis of a distal end of the ink cartridge 1. The sectional view of FIG. 1 is indicated in FIG. 2 by line l-l. Fig. 2 shows a sectional view of the ink cartridge 1 along an axis which is perpendicular to the longitudinal axis of the ink cartridge 1. The sectional view of FIG. 2 is shown in FIG. 1 by line ll-ll.
    The ink cartridge 1 comprises an ink reservoir 3, a tip 14 and an electronic device 4.
    The tip 14 comprises a ball 5 which is retained with possibility of rotation around the center of the ball 5. The ball 5 is arranged so that in each rotational position, a first portion of the surface of the ball 5 is located inside the ink cartridge and a second part of the surface of the ball 5 is exposed outside the ink cartridge, more precisely at the tip 14 of the ink cartridge 1. If the ink is transferred from the ink tank 13 to the surface of the ball 5 in the first part, the ink can be transferred to the outside of the ink cartridge 1 by the rotation of the surface of the ink. ball 5 provided with ink until the second part. This allows the transfer of ink from inside the ink cartridge 1 to the outside of the ink cartridge 1, i.e. to the tip 14, simply by rotating the ink These points 14 are well known in the state of the art of rollerball pens or ballpoint pens. Preferably, the ink cartridge 1 has a longitudinal axis with two distal ends. Preferably, the tip 14 is disposed at a first distal end of the ink cartridge 1. The tip 14 and / or the ball 5 is (are) preferably configured to be electrically conductive (s), so that a signal can be applied for a capacitive, inductive or electromagnetic coupling with a position sensor (for example a tactile device) in order to detect the position of the tip 14 on the position sensor.
    The ink tank 3 is arranged to contain ink. Ink is any material that is configured to color contact a material that needs to be colored. The contact is normally established by the tip 14. The term "color" in the sense of this invention includes any type of color. This includes any color in the classic color spectrum, for example red, orange, yellow, green, cyan, blue, purple. This includes all colors in the broader sense such as black, gray and white. This includes any color outside the visible spectrum of light, for example in the infrared or the ultraviolet, for example for a UV pen. This can also include any mix of colors mentioned. The ink is configured to be deposited on the surface of the ball 5. The ink is also configured to be transferred from the surface of the ball 5 from the first portion to the second portion. The ink is configured to be projected out of the tank as will be explained in more detail below. Preferably, the ink is liquid (also including a viscous state), but it is also possible to materialize the ink in the ink tank 3 with particles. Preferably, the ink cartridge 1 comprises a tubular body 2 forming at least partly the walls of the ink reservoir 3. Along the longitudinal axis of the tubular body 2 and / or the cartridge 1, the reservoir of ink 3 has a first end pointing in the direction of the first distal end of the ink cartridge 1 or the tip 14 and a second end pointing in the direction of the second distal end of the ink cartridge. The second end of the ink tank 3 is preferably materialized by a wall. In the illustrated embodiment, the first end of the ink tank 3 is created by the electronic device 4. However, it is also possible to couple the ink tank 3 with the electronic device 4 in another way. Preferably, the ink cartridge 1 is pre-filled with the ink. The ink cartridge 1 may be disposable. In another embodiment, ink may again fill the ink tank 1, for example from the second end of the ink tank 3.
    The electronic device 4 is configured to transfer the ink from the ink tank 3 on the surface of the ball 5 of the tip 14. According to the invention, the electronic device 4 is configured to create an inkjet 12 which projects the ink from the ink tank 3 on the surface of the ball 5. Therefore, the electronic device 4 is arranged between the ink tank 3 and the ball 5. The walls of the body 2, the device 4 and the first part of the ball 5 form a chamber 11. The surface of the ball 5 (in the first part) is preferably arranged with a distance from the electronic device 4 to secure the electronic device 4 damage resulting from a strong force on the ball. By creating an ink jet 12 in the chamber 11 from the electronic device 4 on the first part of the surface of the ball 5, the ink can be transferred to the ball 5 in a safe and controllable manner. The current technology not only makes it easy to turn on (turn on) or turn off the ink transfer from the ink tank 3 to the ball 5, but it also allows you to control the type of ink pattern created by the tip 14 of the pen. For example, the amount of ink and / or the opening angle of the jet and / or the number of jets may be modified electronically. This could be used to control the intensity of the ink drawn by the tip 14. In the case of at least two ink tanks with different colors, and different jets for each color, a single pen could create on the the surface of the ball 5 a continuous color spectrum by mixing the at least two inks of the at least two ink tanks.
    The electronic device 4 is preferably made by a semiconductor device, for example a silicon chip. Preferably, the electronic device 4 is made by a device with microelectromechanical systems (MEMS). Fig. 1 shows an embodiment of such an electronic device 4. The ink jet 12 is created here by a silicon chip 7 with a piezoelectric element 6. The silicon chip comprises a chamber 9 connected to the reservoir of ink 3 by at least one duct 8 (here four ducts 8). The chamber 9 is connected to the chamber 11, that is to say with the first part of the surface of the ball 5, by at least one nozzle 10. The embodiment shown comprises two nozzles 10, but no any other number of nozzles 10 is possible. The ink jet 10 can be created by activating the piezoelectric element 6 to reduce the volume of the chamber 9 and force the ink through the nozzles 10 on the surface of the ball 5. If the piezoelectric element electrical is not activated, the inkjet 12 is not created and the transfer of the ink on the ball 5 is interrupted. However, alternative embodiments for creating an ink jet are possible. For example, a heating element could create bubbles in the ink, thereby creating a jet of ink jet on the ball 5. The technologies for creating inkjets are well known inkjet printers . These technologies can be used for the electronic device 4.
    The electronic device 4 is preferably controlled by a signal from a pen in which the ink cartridge 1 is installed. However, i! It is also possible for the electronic device 4 to be partly or wholly controlled by a sensor located in the ink cartridge 1 and / or in the pen. A sensor could be used to detect a second mode of operation in which the transfer of the ink onto the ball 5 is to be stopped. This could be done for example by detecting an electrical signal applied to the tip 14 or by detecting the presence of a touch sensor nearby. It is also possible to detect in the first mode of operation, in which the ink is to be emitted by the tip 14, the moment when the ink jet has to be (re) created or interrupted in order to avoid that too much ink is transferred onto the surface of the ball 5 without being deposited on a paper. Such a sensor could detect the rotation of the ball 5, the amount of ink 5 on the surface of the ball 5, the movement of the ink cartridge 1, for example by an accelerometer, etc.
    The ink cartridge 1 is mounted in a pen. The ink cartridge 1 can be mounted such that the ink cartridge 1 can be replaced once the ink cartridge 1 is empty. However, it is also possible to have the ink cartridge in the pen without the possibility of replacement. In this case, the ink reservoir 3 could be refillable or the pen itself is a disposable pen.
    In a preferred embodiment, the pen is an active pen for the application of an electrical signal on the tip 14 and / on the ball 5 of the ink cartridge 1. FIG. 3 shows a schematic view of an embodiment of an active pen 20 with the ink cartridge 1 described above. The active pen 20 comprises the ink cartridge 1, a power supply 21, a controller or control device 22, a pressure sensor 23 and a user input 24.
    The power supply 21 is preferably a battery. However, any other power supply such as an electrical energy collection system could be used. The power supply supplies the power to the controller 22.
    The controller 22 is configured to operate the active pen 20 in a first mode of operation wherein the ink from the ink tank 3 is transferred by the ink jet 12 to the ball 5. The controller 22 is further configured to operate the active pen 20 in a second mode of operation wherein the transfer of ink from the ink tank 3 to the ball 5 is stopped. Therefore, the controller 22 is electrically connected to the electronic device 4. The controller 22 is further electrically connected to the tip 14 and / or the ball 5 of the ink cartridge 1 in order to apply, in the second mode of operation, an electrical signal at the tip 14 and / or the ball 5. The electrical signal is configured to create a capacitive coupling, inductive or electromagnetic with a position sensor. The electrical signal is preferably a periodic signal, such as an alternating voltage at a certain frequency. In the illustrated embodiment, the controller 22 has two separate contacts to make contact with the tip 14 and / or the ball 5 and to make contact with the electronic device 4. However, it is also possible that the electronic device 4 and the tip 14 and / or the ball 5 are connected to the controller 22 by the same electrical line.
    The user input 24 is configured to switch between the first and second operating mode. However, it is also possible that the switching between the first and the second operating mode is not performed by the user, but by a sensor. User input 24 could further include a switch to turn off the pen 20 power supply. User input 24 could also include the ability for the user to control the inkjet 12 settings. User input 24 could be a button or a switch or a more complex user interface, for example with a plurality of buttons or switches.
    As an option, the active pen 20 could constitute a pressure sensor 23 for measuring the pressure acting on the tip 14 and / or the ball 5, when the active pen operates in the second mode of operation. The measured pen pressure can be transferred with the electrical signal from tip 14 to the position detector. The pressure sensor 23 normally requires that the ink cartridge 1 move along the longitudinal axis of the pen 20. In one embodiment, the movement along the longitudinal axis of the pen 20 is blocked in the first operating mode.
