Description

  The present invention relates to a switch with a display function in which a rewritable display unit is provided on the switch, and an operation device having the switch with a display function.

  High functionality of various devices used in daily life such as home appliances and electronic devices is progressing. Along with this high functionality, a large number of switches are arranged on the operation panel for directly operating the apparatus. The size of the operation panel is limited by the size of each device. Since the device has been miniaturized while increasing its functionality, the input components constituting the switch have been reduced. As a result, the display of the function of the switch is abbreviated, and therefore it is difficult to recognize the function. Therefore, in order to use the device, the function of each switch must be understood and stored, and the operation panel is not used. It was difficult.

  On the other hand, remote control devices for remotely operating devices such as home appliances and electronic devices are widely used. Remote control devices are also equipped with a large number of switches as various devices become more sophisticated. In the remote control device, the switches are arranged with a size that can be held by a human hand, so that there is not enough area to display the function of each switch. For this reason, also in the remote control device, the display of the function of the switch is an abbreviation that makes it difficult to recognize the function. Furthermore, in a device having a complicated function such as an audio device, since a switch has a plurality of functions, the function of the switch has become unclear. As described above, the use of the device using the remote control device requires understanding and storing the function of each switch for each remote control device, which makes operation difficult.

  There has been proposed a remote control device that includes a switch and a liquid crystal display unit and displays the contents of the operation on the display unit (see, for example, Patent Document 1). The remote control device switches the operation mode each time the switch is pressed. The operation mode of the apparatus is printed outside the liquid crystal display unit, and when the operation mode is switched, the video information on the liquid crystal display unit is rewritten to display which operation mode is selected. In this remote control device, the liquid crystal display unit is rewritten every time the switch is pressed. However, since the function of the switch is fixed, it is difficult to apply to a multi-function device. In addition, since the number of liquid crystal display portions equal to the number of functions of the switch is necessary, the functions that can be provided in the remote control device are reduced.

Furthermore, there is a touch panel as a multifunction switch. The touch panel performs a plurality of functions in one input part. However, since the inside of the frame displayed on the liquid crystal is the input part, the user of the touch panel has to touch the input part without putting any hand close to the liquid crystal and touching the other part. For this reason, the touch panel could not be applied to a remote control device because it would cause an erroneous operation of the device when carried by hand. Furthermore, since the inside of the frame displayed with the liquid crystal is the input part, the input part is unclear. The fact that the input part is unclear is clear from the fact that an automatic teller machine of a financial institution has an input switch separately from the touch panel. For this reason, the user of the touch panel has to visually confirm whether the input part is the input part desired by the user, and is not suitable as an operation panel used in daily life.
Japanese Patent Laid-Open No. 9-182178

The switches provided on the operation panels and remote control devices of various devices are provided with many switches and have poor operability. Or the switch which can perform complicated operation was contrary to the convenience at the time of normal use since it was not only complicated in operation but also complicated in structure. Even if the functions used for normal use are limited, the operability is inferior to cope with higher functionality.
In order to solve the above problems, an object of the present invention is to provide a switch that is simple and excellent in operability or an operation device including the switch.

  The present invention is a switch with a display function in which a switch having a shape that can be perceived as an input component by visual or tactile sensation is provided with an electronically rewritable display unit. The display unit displays the function of the switch using characters, images, photos, icons, and the like. Like a conventional operation panel or a remote control device, each switch can be perceived by visual or tactile sense as an input component, which is excellent in operability.

  Since the display portion can be rewritten, even when one switch has a plurality of functions, only the function of the switch at that time can be displayed. Since it is not necessary to display functions that are not performed at that time, the switch user can be prevented from being confused. Even if a single switch has many functions, there is no confusion, so the number of switches provided in the operation panel and the remote control device can be reduced, and the display for one switch can be enlarged. Accordingly, it is possible to provide a switch and an operation device that are simple and excellent in operability.

  Specifically, the switch with a display function according to the present invention receives an electronically rewritable display unit that displays video information such as characters, images, photos, icons, and the video information to be displayed on the display unit. A video input unit that outputs the input video information to the display unit, a switch that detects on / off or on / off and an input level of the switch, and a switch that the sensor detects. It has at least an on / off and an output unit of an input level, and has a shape that can be perceived as an input component. By providing the electronically rewritable display unit in a switch having a shape that can be perceived as an input component, it is possible to clearly display operations that can be performed by the switch. Therefore, it is possible to provide a switch that is simple and excellent in operability.

  The sensing unit may be disposed on the display surface of the display unit, or may be disposed on the back surface of the display unit, or may be disposed on the same surface as the display surface of the display unit. Also good. The sensing unit can be arranged on the surface of the switch by arranging the sensing unit on the display surface of the display unit or on the same plane as the display surface of the display unit. Accordingly, a sensing unit that directly senses that the switch has been input can be provided. Further, the sensing unit is arranged on the back surface, that is, the back surface of the display surface of the display unit, so that the display unit can be arranged on the surface of the switch. As a result, the display unit can be arranged in a portion that is easy for humans to see. Therefore, the display unit can display a fine image outside the switch with a display function.

  The sensing unit may be a pressure sensor that senses pressurization, an electrostatic sensor that senses a change in capacitance, or an ultrasonic sensor that senses a reflected wave of a transmitted ultrasonic wave, Alternatively, it is preferable to sense the on / off or on / off and input level of the switch by an optical sensor that senses light, an electromagnetic wave signal, or a change in electrical resistance.

  Used by sensing the switch on and off or on and off and the input level by the pressure sensor that senses pressurization by the sensor or by the electrostatic sensor that senses the change in capacitance The person can confirm that the input has been made by feeling that the switch having a shape that can be perceived as an input component is pressed.

  By sensing the on / off or on / off and input level of the switch by the ultrasonic sensor that senses the reflected wave of the transmitted ultrasonic wave, or by the optical sensor that senses the light The user can input the switch only by approaching the switch having a shape that can be perceived as an input component. In addition, the sensing unit senses on / off or on / off and an input level of the switch by the electromagnetic wave signal, so that the user can input the switch using the electromagnetic wave signal from a place away from the switch. In addition, the sensing unit senses the on / off of the switch or the on / off and the input level according to the change of the electric resistance, so that an arbitrary input level can be input.

  The display unit holds the displayed video information even when no power is supplied, holds the video information displayed with a slight amount of power supplied by the battery, or is supplied from the outside. It is preferable to hold the video information displayed by power. The display unit retains the displayed video information even when power is not supplied, or holds the video information displayed with a small amount of power supplied by the battery, so that the switch with a display function rewrites the display unit. Since power is used only when power is consumed, power consumption can be reduced. In addition, the display unit holds the video information displayed by the power supplied from the outside of the switch with the display function, so that the switch with the display function can continue to display the video information on the display unit even when the switch is not used. it can.

  It is preferable to include at least one of a memory that stores and saves video information output from the video input unit and a central processing unit that outputs video information output from the video input unit to the display unit. By providing a memory that stores and saves video information output from the video input unit, the display unit can always display the video information without being input from an external system. Further, by providing the central processing unit that outputs the video information output from the video input unit to the display unit, the video input unit can receive video information having a signal form different from the signal form used in the display unit. As a result, the video information can be input to the switch with a display function in an arbitrary signal form, so that the video information can be input to the video input unit using a transmission method suitable for the use environment.

  The display unit and the sensing unit are separable, and the display unit may further include an input terminal for receiving the video information. As a result, any combination of the sensing unit and the display unit is possible. Furthermore, since the display unit and the sensing unit are separable, a switch with a display function can be provided by newly providing a display unit in the existing switch.

  An attachment / detachment unit that detachably fixes the display unit and the sensing unit may be further provided. Since the display unit and the sensing unit can be separated, and the display unit and the sensing unit are detachable, a new display unit can be provided in an existing switch, and the display unit can be fixed and integrated.

  Another switch with a display function according to the present invention is a switch with a display function in which at least two switches with the display function are arranged adjacent to each other, and the display units adjacent to each other are connected to each other. The video information for each sensing unit is displayed when the sensor is attached to each sensing unit. Provided is a switch with a display function in which a desired sensing unit and a desired display unit are combined even when a plurality of switches with a display function are provided by separating the connected display unit and the connected sensing unit from each other. be able to. Furthermore, existing switches that are connected so as to be adjacent to each other can be made into switches with a display function in which each switch has a display unit.

  An operation device according to the present invention is an operation device provided with at least two switches with the display function, and is in a desired device type or device mode among one or more types of devices to be controlled. In response, the video information displayed on each display unit is electronically rewritten. As a result, an operation device that is simple and excellent in operability becomes possible.

  According to the present invention, it is possible to provide a succinct and excellent operability switch compatible with a high-function apparatus or an operation device including the switch.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, this invention is not limited to the Example shown below.
(Embodiment 1)
An example of an embodiment of a switch with a display function according to the present invention is shown in FIG. FIG. 1 is a system configuration diagram of the first embodiment. The system shown in FIG. 1 includes a switch 91 with a display function and an external system 81. The switch 91 with a display function receives an electronically rewritable display unit 11 that displays video information such as characters, images, photos, icons, and the like, and video information A1 that is displayed on the display unit 11. A video input unit 14 that outputs A1 to the display unit 11, a switch 13 that senses on / off or on / off and an input level of the switch, and an on / off or on / off of the switch that the sensor 13 senses. And an output unit 15 that outputs the input level as the input signal B1.

  The external system 81 includes a video output unit 21 that outputs video information to the video input unit 14, an external output unit 22 that outputs the input signal B1 output from the output unit 15, and video information A1 and an operation signal D1. A central processing unit 24 for outputting to the video output unit 21 and the external output unit 22, a memory 25 for storing and storing the video information A1 and the operation signal D1, a main power supply 26 for supplying power P to the external system, and a display unit 11 and a sub power source 27 that supplies electric power P to the sensing unit 13. The external system 81 is an example, and the present invention is not limited to this. In FIG. 1, B1 is input information for outputting on / off or on / off and input level of the switch detected by the sensing unit 13, D1 is an operation signal for operating the apparatus, and A1 is an image corresponding to the operation signal D1. Information, P indicates power. D2 (not shown) is an operation signal different from D1 for operating the apparatus, and A2 (not shown) is video information corresponding to the operation signal D2.

  The switch 91 with a display function will be described. The switch 91 with a display function has a shape that can be perceived as an input component. FIG. 2 shows an appearance example of the switch 91 with a display function. FIG. 2 is a perspective view of the switch 91 with a display function. As shown in FIG. 2A, the switch 91 with a display function may be one in which the switch 91 with a display function protrudes from a three-dimensional base 96. Since the switch 91 with a display function protrudes from the base 96, it can be perceived by touch and sight that it is an input part. Further, the switch 91 with a display function may not protrude from the base 96. In this case, as shown in FIG. 2B, the shape of the switch 91 with a display function is printed on the surface of the base 96 that is in contact with the switch 91 with a display function using lines and colors. Can be perceived visually. By making the base 96 and the switch 91 with a display function different materials and different surface shapes, it may be possible to perceive that it is an input part by tactile sensation.

  The display unit 11 is electronically rewritable that displays video information such as characters, images, photos, icons, and the like. The display mechanism is not limited. For example, an organic EL display, a liquid crystal display, a PDP (plasma display panel), or an FED (field emission display) may be used. The displayed video information may not be affected by impact, electromagnetic waves, or the like. The display unit 11 may hold video information displayed by the power P supplied from the outside of the switch 91 with a display function. Accordingly, the switch with a display function can continue to display the video information on the display unit even when the switch is not used. The display unit 11 may hold the displayed video information A1 even when no power is supplied. For example, characters or images may be displayed by moving colored particles by electrophoresis. For example, the microparticle liquid crystal may be rewritten by applying energy such as negative ions or heat from the outside. For example, a non-volatile liquid crystal display may be used. In this case, the display unit 11 holds the displayed video information even when the power P is not supplied. The display unit 11 may hold the video information A1 displayed with a small amount of power that is supplied by the battery. The display unit may hold video information displayed with a small amount of power supplied by a battery provided in a switch with a display function. For example, in an organic EL display, the applied voltage can be displayed at 5 to 10V. Here, the battery may be a battery such as a button battery. The battery may be capable of storing external energy such as an external system or sunlight as electric power. Further, the battery may be provided inside the switch with a display function, or may be provided outside the switch with a display function. Accordingly, since the display unit 11 uses power only when the display unit 11 is rewritten, the power consumed can be reduced.

  Here, the video information A1 is contents to be displayed on the display unit 11 such as characters, images, photos, icons, and the like. The file format of the video information A1 is not limited. For example, still images such as HTML format, XML format, PDF format, JPEG format, GIF format, TIFF format, and MPEG format may be used. It may be a video in QuickTime format, AVI (Audio Visual Interleaved) format, Real Audio format, or Windows (registered trademark) Media format. It may be an NTSC signal, a PAL signal, or an analog signal such as Red, Green, Blue, Hs, Vs, and Cs.

The video input unit 14 receives video information A1 to be displayed on the display unit 11 and outputs the input video information A1 to the display unit 11. The video input unit 14 may be a digital signal connector such as USB, EIA232C, IEEE1394, or the like. D-Sub
For a video signal of a personal computer such as a 15-pin connector, a mini D-Sub 15-pin connector, or a DVI-D connector. It may be a composite video signal for video equipment such as a pin plug, a pin jack, or the like. It may be for a separate signal such as an S terminal. A radio signal using infrared rays or the like may be received. The output unit 15 outputs the on / off or on / off and input level of the switch sensed by the sensing unit 13. For example, the output unit 15 may output the on / off of the switch or the on / off and the input level to the external output unit 22 as the input signal B1. The configuration of the output unit 15 is not limited. For example, a connector for connecting to the external output unit 22 by information wiring may be used. Further, a wireless device using infrared rays or radio waves may be used. By using a wireless device, a movable switch with a display function is possible. Further, a pulse generation mechanism using a piezoelectric element and a coil may be used. Necessary electric power is generated by the piezoelectric element, and the input signal B1 can be output to the outside with the generated electric power. The input signal B1 is a signal for outputting the on / off of the switch sensed by the sensing unit 13 or the on / off and the input level. The input signal B1 may be an electrical signal or an optical signal. Switching on and off may be turned off when no current flows through the sensing unit, and may be turned on when current flows through the sensing unit. The input level of the switch may be the magnitude of the signal output of the signal.

  The sensing unit 13 senses on / off of the switch or on / off and an input level. The sensing unit 13 may sense as an analog value or may sense as a digital value. The configuration for sensing the on / off of the switch or on / off and the input level is not limited. For example, the sensing unit 13 may sense a switch on / off or on / off / input level according to a change in electrical resistance. The change in the electrical resistance includes a case where the electrical resistance is changed in accordance with the movement of the sensing unit (up, down, left, right, etc.), and may be one that senses the input level according to the value of the electrical resistance. The input level corresponding to the value of the electrical resistance may be a continuous value (analog value) or a stepped value (digital value).

(Switch example 1)
A specific example of the switch with a display function according to the present invention is shown in FIG. FIG. 3 is a configuration diagram illustrating an example of a switch with a display function to which a mechanical switch is applied. The switch with a display function shown in FIG. 3 includes a display unit 11, an input member 12, a video input unit 14, an output unit 15, a spring 31, a leaf spring 32, a fixing unit 34, a contact unit 33, and 37, video wirings 35 and 36, and information wirings 38 and 39. The sensing unit is a mechanical switch, and includes an input member 12, a spring 31, a leaf spring 32, contact parts 33 and 37, and a fixed part 34.

  The input member 12 is the same as the input part of the mechanical switch used for the keyboard. One of the input members 12 is provided with a protrusion 40 and the other is provided with a display unit 11. The fixing portion 34 is fixed to the base 96 shown in FIG. One end of the spring 31 is fixed to a part of the fixing portion 34, and the other end of the spring 31 is in contact with the tip of the protrusion 40 of the input member 12. One end of the leaf spring 32 is fixed to the fixing portion 34, and a part of the leaf spring 32 is in contact with the tip of the protrusion 40 of the input member 12. The leaf spring 32 and the fixing portion 34 are provided with a contact portion 33 and a contact portion 37, respectively. The output unit 15 is provided on the bottom surface of the fixed unit 34. The contact part 37 and the output part 15 are connected by an information wiring 38. The video input unit 14 is provided on the bottom surface of the fixed unit 34. The display unit 11 and the video input unit 14 are connected by a video wiring 35.

  The operation of the switch with the display function will be described with reference to FIG. The video input unit 14 receives the video information A <b> 1 output from the video output unit 21 through the video wiring 36. The video input unit 14 outputs the input video information A1 to the display unit 11 through the video wiring 35. The display unit 11 displays the video information output from the video input unit 14. When the display unit 11 is pushed down toward the fixed unit 34, the contact units 33 and 37 are brought into contact with each other and become conductive, so that the sensing unit senses that a switch has been input. When the switch is input, the output unit 15 outputs input information B1. The sensing unit may sense the on / off of the switch and the input level according to the number of times the switch is input, and may output the on / off of the switch and the input level from the output unit 15. The above is an example of a switch with a display function to which a mechanical switch is applied. By applying the mechanical switch in this way, the sensing unit can be configured without supplying power. By sensing the on / off or on / off and input level of the switch according to the change in electrical resistance caused by the depression of the sensing unit 13, the user depresses the switch having a shape that can be perceived as an input component. It can be confirmed that the input has been made by the sense that The mechanical switch may have a latch.

(Embodiment 2 of the switch)
The sensing unit 13 may sense, for example, a switch on / off or on / off / input level by an optical sensor that senses light. A specific example of another switch with a display function according to the present invention is shown in FIG. FIG. 4 is a longitudinal cross-sectional view showing an example of a switch with a display function including a light sensor whose light is sensed by the sensing unit. The switch with a display function shown in FIG. 4 includes a display unit 11, an input member 12, a sensing unit 13, a video input unit 14, an output unit 15, video wirings 35 and 36, and information wirings 38 and 39. , Is configured. The input member 12, the display unit 11, and the sensing unit 13 are arranged in an overlapping shape in order. The center of the surface facing the display unit 11 of the sensing unit 13 is recessed. The video input unit 14 is disposed on the input member 12 and is connected to the display unit 11 by a video wiring 35. The output unit 15 is disposed on the input member 12 and is connected to the sensing unit 13 by the information wiring 38.

  The sensing unit 13 includes an optical sensor that senses on / off of the switch or on / off and an input level by sensing light. In Example 2, a depression is provided on the surface, and light sensed inside the depression is sensed. The optical sensor provided in the sensing unit 13 senses light. For example, an infrared sensor capable of sensing light of a specific wavelength such as a human body temperature may be used. In this case, the wavelength that can be sensed is limited to the human body temperature, and infrared light incident from the vicinity of the switch may be sensed by the intensity obtained by approaching within a certain distance. Alternatively, infrared light may be emitted from the vicinity of the sensing unit 13 and the infrared light reflected near the switch may be sensed. Moreover, what applied the thing which converts the energy of a photon into an electrical signal, such as photodiodes, such as a silicon photodiode, photoelectric conducting elements, such as CdS, a photoelectric tube, and a pyroelectric sensor, may be applied. The light sensed by the optical sensor is not limited. Visible light may be used. As described above, the optical sensor may be one that only detects light, or one that detects reflected light of light emitted from the detection unit.

  The operation of the switch with a display function of the second embodiment is almost the same as that of the first embodiment. The difference from the first embodiment is only the sensing method. The sensing unit 13 according to the second embodiment can output the fact that the switch is input from the output unit 15 as the input information B1 in FIG. 1 by sensing infrared rays inside the depression of the sensing unit 13, for example. As described above, the switch with a display function may be manufactured by a configuration in which the sensing unit 13 senses the on / off of the switch or the on / off of the switch and the input level by the light sensor that senses light. As a result, the user can input the switch only by approaching the switch having a shape that can be perceived as an input component.

  Although the sensing unit 13 of the second embodiment is an optical sensor, the sensing unit 13 is not limited. For example, a switch may be configured to detect the on / off or on / off / input level of the switch based on the pressure applied to the depression of the sensing unit 13 using a pressure sensor. For example, a switch may be configured to sense the on / off or on / off / input level of the switch based on a change in the capacitance of the surface of the sensing unit 13 when it comes into contact with the depression of the sensing unit 13 using an electrostatic sensor. For example, an electromagnetic wave is emitted from a part of the sensing unit 13 and an on / off or on / off and input level of the switch is sensed by reading an electromagnetic wave signal acted by a chip or coil included in an IC or the like. Good. For example, the switch may be configured to sense the on / off or on / off / input level of the switch by receiving an electromagnetic wave signal emitted from the outside. If the electromagnetic wave signal emitted from the outside can be read, the user can input the switch using the electromagnetic wave signal from a place away from the switch, and thus the remote operation of the switch becomes possible. Further, the sensing unit 13 may be integrated with the base 96 as shown in FIG. Moreover, in Example 2, although the hollow was provided in the center of the sensing part 13, a flat thing may be sufficient.

  The sensing unit 13 may be disposed on the display surface of the display unit 11 as shown in FIG. FIG. 5A is a cross-sectional view illustrating an example of a state in which the sensing unit 13 is disposed on the display surface of the display unit 11. One side of the display unit 11 is a display surface 19. In FIG. 5A, the display unit 11, the display surface 19, and the sensing unit 13 are arranged in an overlapping manner in the direction E. The direction in which the display surface 19 is arranged with respect to the display unit 11, that is, the direction E shown in FIG. 5A is the display direction of the display unit 11. As described above, the sensing unit 13 may be provided on the display surface of the display unit 11 to include a sensing unit that senses that a person or an object is touched. In addition, the sensing unit 13 may be disposed on the back surface of the display surface of the display unit 11 as illustrated in FIG. FIG. 5B is a cross-sectional view illustrating an example of a state in which the sensing unit 13 is disposed on the back surface of the display surface of the display unit 11. The sensing unit 13 may be arranged in the order of the sensing unit 13, the display unit 11, and the display surface 19 in the direction E. As described above, the sensing unit 13 is arranged on the back surface of the display surface of the display unit 11, whereby the display unit 11 can be arranged in a portion that is easy for humans to see. Thereby, the display unit 11 can display a fine image on the outside of the switch 91 with a display function.

(Example 3 of switch)
The sensing unit may be disposed on the same plane as the display surface of the display unit. A specific example of another switch with a display function according to the present invention is shown in FIG. FIG. 6 is a front view showing another configuration example of the switch 97 with a display function according to the present invention. The switch 97 with a display function includes a display unit 41 that displays video information on a base 96, and ultrasonic transmission units 42 a and 42 b and ultrasonic sensors 43 a and 43 b arranged around the display unit 41. ing. For example, when an object that reflects ultrasonic waves approaches the surface of the display unit 41, the ultrasonic sensors 43a and 43b convert the reflected ultrasonic waves transmitted from the ultrasonic transmission units 42a and 42b to the ultrasonic sensors 43a and 43b. It is received at 43b and senses the on / off or on / off and input level of the switch. In addition, although the example provided with the ultrasonic sensor which detects the reflected wave of the transmitted ultrasonic wave was shown in Example 3, the detection part with which the switch 97 with a display function is provided is not limited to this.

  The configuration in which the sensing unit is disposed on the same surface as the display surface of the display unit is not limited to the third embodiment of the switch, and the display unit and the sensing unit may be alternately arranged in a grid pattern. Good. The display unit is, for example, an RGB light emitting diode (LED), and the RGB ones may be integrated or separated. The sensing unit is, for example, a charge coupled device (CCD) and may be capable of receiving light for each of RGB.

  The sensing unit 13 may be one that feeds back a tactile sensation when a switch is turned on or off or on and off and an input level is input. An access sound such as a keyboard touch sound or a mouse click sound may be used. The light emitting element may emit light. If a piezoelectric element is used for the sensing unit and the light emitting element emits light by the generated electric power, the light can be emitted without supplying power. The access sound and the emission wavelength may be varied depending on the on / off or on / off and input level of the switch.

  An example of the configuration of the external system 81 will be described. The main power supply 26 supplies power P to the external system 81. Any power supply can be used, and a power supply outlet can be used. The sub power source 27 supplies power P to the output unit 11 and the sensing unit 13. The memory 25 stores and saves an operation signal capable of operating the apparatus and video information corresponding to the operation signal. The operation signal and the video signal correspond to each other, for example, the operation signal D1 and the video information A1, the operation signal D2 (not shown), and the video information A2 (not shown) correspond to each other. The central processing unit 24 reads the video information A1 and the operation signal D1 from the memory 25 and outputs them to the video output unit 21 and the external output unit 22. The video output unit 21 outputs the video information A1 to the video input unit 14. The external output unit 22 outputs an operation signal D1 for operating the apparatus based on the input signal B1 output from the output unit 15.
