Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information display device for displaying various information on the screen of a display device such as a CRT.

[0002]

2. Description of the Related Art Conventionally, a display device (information display means) in an information display device of a personal computer (hereinafter referred to as a "personal computer") mounted on some automobiles (vehicles) is usually in front of a driver's seat. It is installed in a state in front of the change lever of the instrument panel in. And on this display device,
For example, the map information and the current position of the vehicle are displayed on this map, and the driver can drive without hesitation even at the first place by seeing the displayed contents.

In addition, conventionally, an information display device in a personal computer or the like has been known which includes a window display system for displaying a window on its screen. Then, in such a window display system, "Wind
ow 3.0 ”has a function called“ recorder ”.

This is to record all the input operations such as the movement of the mouse cursor by the user on the window displayed on the screen, the click of the mouse button or the key input, and the recorded input operation is automatically recorded later. It is something that can be reproduced.

By the way, in the world of industrial robots, there are first-generation playback robots and second-generation intelligent robots, and the main focus is on intelligent robots at present.

The playback type robot is a robot that faithfully records the work motion of a skilled worker and reproduces the recorded work motion to automatically perform the work, and is used in a painting process or the like. ing.

On the other hand, the intelligent robot has a built-in television camera, makes a judgment on an object by image processing, and carries out a corresponding operation, and is used in a machine assembling process or the like. There is.

Further, in the past, information display devices for personal computers and the like have been researched by NASA (American Aeronautics and Space Administration) in the United States, etc., and have a virtual reality (AR).
ty) is known to be equipped with a system.
In this system, a head-mounted goggle type display (information display means) generally called a head mounted display, a glove type sensor and a direction sensor called a data grope are connected to the computer main body, Puts a goggle type display on both eyes, wears a glove sensor on his right hand and a direction sensor on his head.

Then, an image viewed from a position in a virtual space where the buildings and the like constructed in the computer are lined up is displayed on the goggle type display. If the user wants to see the space in the desired direction while looking at the image, he can turn his head in that direction. The direction sensor immediately and continuously detects the rotation angle of its neck and informs the computer body. Then, the computer body automatically creates an image of the virtual space in the direction corresponding to the angle according to the angle and displays it on the goggle type display.
By executing this continuously without interruption, the user can stand in the virtual space constructed in the computer and experience the virtual world.

When the user moves the glove-shaped sensor with the right hand, the image of the right hand also appears in the virtual space, and an operation of grabbing an object in the virtual space, an operation of pointing a certain object, or a menu appears. It is possible to simulate an operation of selecting a predetermined process by using the above.

In many cases, in the goggle type display, the images for the left eye and the right eye are divided, and the image for the left eye and the image for the right eye are displayed respectively, and the user virtually It is possible to stereoscopically view different spaces.

[0012]

However, in the above-mentioned conventional information display device mounted on an automobile, when the driver views the display screen, the line of sight is completely from the front of the vehicle to the front of the change lever. Since it has to be transferred to a display device, there is a problem that it is very dangerous to perform such a line-of-sight movement during driving. Therefore, some vehicles have a fail-safe function of displaying a map or the like on the display screen only while the vehicle is stopped without displaying the display while the vehicle is running.

Further, more recently, a vehicle equipped with a system in which the display screen is reflected on the windshield surface so that the driver can see the display screen has appeared. This system is an application of a head-up display that has been used for a long time in aircraft, especially fighters. As a result, the driver's line-of-sight movement while traveling is reduced.

However, in this case as well, when the driver's line of sight at a medium speed is 30 m in front of the vehicle and he or she tries to look at the display screen reflected on the windshield, the line of sight is 30 m in front of the vehicle. The position must be abruptly moved to a position of several tens of centimeters in front of the eye, which is near the front glass.

At this time, the line of sight itself is not in focus even if it faces the front of the vehicle, so 30 m in front of the vehicle.
Even if there is an obstacle ahead, it is hard to notice, and it is virtually as dangerous as driving aside.

In such a case, by mounting Fresnelnes of an appropriate frequency on the front surface of the display screen and reflecting the display screen on the windshield surface,
The driver can see the virtual image on the display screen generated 30 m in front of the vehicle. As a result, the focus position of the line of sight in front of the vehicle matches the focus position of the display screen, so the driver can safely view the map displayed on the display screen without changing the focus of the line of sight even while driving. be able to.

However, an automobile constantly repeats vertical vibrations during traveling due to road surface conditions, and accordingly, the body of the driver himself also repeats vertical motions on the seat at a frequency of 1 Hz to several Hz.

Therefore, assuming that the display device is fixed to the vehicle, the virtual image of the display screen generated 30 m in front of the vehicle also moves up and down simultaneously with the vertical movement of the driver's eye position. It becomes difficult to see. Moreover, the farther the virtual image position is from the front of the vehicle, the more the vertical movement of the virtual image tends to increase.

Further, in the information display device provided with the window display system having the "recorder" function,
Since the user's input action is only recorded faithfully in advance in order, if a situation slightly different from the state at the time of recording when reproducing that action, it is impossible to reproduce the operation after that. There is a problem that it becomes.

The above-mentioned "different situation" means, for example, a warning message that was not displayed at the time of recording is displayed on the screen and the user's clicking operation of the "OK" button is requested, or the button display position at the time of recording and reproduction. When the button display position of is deviated, and the "button display" click by the mouse cursor is not executed at the time of reproduction, or the like.

As described above, the reproduction function of the "recorder" is premised on that the state is exactly the same as the state at the time when the reproduction of the operation is started and during the reproduction of the operation.

However, in this case, even if the user uses the "recorder" function to perform general-purpose information processing on the window display system, the "recorder" reproduction function has a judgment function for an unexpected situation. It is impossible because there is no.

Therefore, it can be said that this "recorder" function can be used for a specific application only for repeatedly executing the demonstration.

Further, in an application operating on a window display system, generally, a user generally operates a mouse button or a keyboard in an interactive manner to proceed with processing while watching a window displayed on a display. Therefore, unless a user inputs interactively, a television camera like a so-called intelligent robot has a built-in television camera, makes a judgment operation on an object by its image processing, and automatically works. Not proceed.

Further, in the above-mentioned conventional information display device for constructing the virtual reality system, only the glove-type sensor is used as the input means from the user, and in consideration of the case of practical use, the characters are input. An input means for doing this is required.

If a keyboard is used as the input means, it becomes possible to input characters. However, when the user inputs a key from the keyboard, it is necessary to first remove the glove-type sensor of the right hand and then operate the keyboard, and with the goggle type display, it is not after removing it. And it is difficult to operate the keyboard. When this goggle type display is attached, both eyes are completely covered, so it is not easy to know where the keyboard is. Even if it can be operated, the arrangement of special keys such as ESC key and ALT key is
Since it depends on the type of keyboard, it is impossible to perform an input operation by complete blind touch, and there is a possibility that a mistaken key input will occur each time a special key is pressed.

The present invention has been made in view of the above circumstances. A first object of the present invention is to provide an information display for forming a display image which is easy to see while maintaining safe driving for at least a driver of a running vehicle. It is to provide a device.

A second object of the present invention is to provide an information display device capable of automatically executing program processing without input from a user in an interactive manner.

A third object of the present invention is to provide an information display device which enables a user to input information while wearing the information display means while looking at the input means.

Embodiments of the present invention will be described below with reference to the drawings.

[First Embodiment] FIG. 1 is a schematic view showing an application example in which the information display device according to the first embodiment of the present invention is mounted in front of a driver's seat of an automobile.

In the figure, reference numeral 1 is a controller, which controls pressure information from a pressure sensor 3 provided on a seat 2 and vehicle speed information from a vehicle speed sensor 5 provided on an axle of a wheel 4. Based on this, the stepping motor 6 is controlled. The stepping motor 6 is connected to a gear 7, and the gear 7 meshes with a gear 9 provided under the display computer device 8. This display computer device 8 is rotatably attached to a support column 10 attached to a vehicle body (vehicle) 11 via a shaft 12, and the gear 9 is denoted by A in FIG.
Or, in the figure, C is centered around the shaft 12 with the rotation in the B direction.
Or it swings in the D direction.

As a result, the controller 1 samples the pressure information from the pressure sensor 3 at predetermined time intervals (for example, 0.05 seconds), and the vehicle speed sensor 5 determines whether the vehicle is currently stopped or running. In this case, the stepping motor 6 can be operated according to the momentary change of the pressure value obtained from the pressure sensor 3 to swing the display computer device 8.

Further, the display computer device 8 is
It has a display unit 13 for displaying map information and the current position of the vehicle on this map, and a Fresnel lens 14 provided on the front surface of this display unit 13. The Fresnel lens 14 is for generating a virtual image 15 of the image (screen) displayed on the display unit 13 at a position 30 m in front of the vehicle body 11.

That is, by reflecting the image displayed on the display unit 13 through the Fresnel lens 14 on the surface of the windshield 16, the driver 17 can see this image 30 m ahead of the vehicle body 11. Become.

The image of the display unit 13 itself is an upside down image so that the driver 17 can see the image normally only after it is reflected by the surface of the windshield 16.

The relationship between the fluctuation of the pressure value and the direction of the oscillating movement of the display computer device 8 is such that, for example, when the pressure value detected by the pressure sensor 3 is decreasing, the body of the driver 17 is accompanied by it. Is being lifted, the device 8 is accordingly controlled to shift the angle upward in the windshield 16. As a result, when viewed from the driver 17, the virtual image 15 is maintained in a stationary state at a certain forward position.

In this case, the angle θ of the device 8 is changed by a value proportional to the displacement of the pressure value. The proportional constants at this time are the number of teeth and the radius of the gear 7 of the stepping motor 6, the display computer device. 8, the number of teeth of the gear 9 provided in the lower part of 8, and the distance R from the center of the shaft 12 to the gear 9,
It can be theoretically calculated from the distance L between the windshield 16 and the center of the shaft 12, the inclination angle φ of the windshield 16, and the like. In practice, it is determined by correcting the theoretically calculated proportionality constant based on the test results of the actual vehicle.

FIG. 2 is a block diagram showing a schematic configuration of the controller 1 of FIG. In the figure, reference numeral 1-1 denotes a central processing unit (hereinafter referred to as "CPU"), which controls the entire controller 1. 1-2 is a memory, which is a read-only memory (hereinafter,
Called "ROM". ) 1-3 and a random access memory (hereinafter referred to as “RAM”) 1-4, and R
The OM1-3 has a built-in program for controlling the entire controller 1. The CPU 1-1 operates according to this program procedure and controls the entire controller 1.
RAM1-4 are used as a work area at the time of program execution. 1-5 is a pressure sensor interface,
It has a function of returning the pressure data from the pressure sensor 3 to the CPU 1-1 side when the CPU 1-1 issues a pressure sampling command. Reference numeral 1-6 is a vehicle speed sensor interface, which outputs vehicle speed data from the vehicle speed sensor 5 to the CPU 1 when the CPU 1-1 instructs the vehicle speed sampling.
It has the function of returning to the -1 side. A stepping motor interface 1-7 has a function of rotating the stepping motor 6 by an angle instructed by the CPU 1-1.

The angle command is 360 ° for one rotation.
In some cases, the number of rotations may exceed several, and the rotation direction may be forward or reverse.

FIG. 3A shows the pressure value measured by the pressure sensor 3 and sampling for each unit time, and FIG. 3B shows the displacement of the pressure value which changes momentarily based on the pressure sampling. ing.

The controller 1 rotates the stepping motor 6 and swings the display computer device 8 in a form proportional to the pressure displacement value.

From an analog point of view, the pressure displacement curve is obtained by differentiating the pressure curve.

Next, the control operation of this embodiment will be described with reference to FIG.

FIG. 4 is a flowchart showing a control operation procedure by the controller 1 of FIG.

This control operation starts when the power source is turned on, that is, when the driver starts the engine of the automobile.
First, in step S1, it is checked whether the power is off, that is, whether the engine is in a stopped state. If the engine is in a stopped state, the angle θ of the display computer device 8 is returned to the state when the power was turned off, and The control operation ends. If the engine is not stopped, the vehicle speed sensor interface 1-6 is instructed to sample the vehicle speed in step S2, vehicle speed data is obtained, and it is checked in step S3 whether the vehicle body is currently stopped. If the vehicle body is stopped, it is checked in step S4 whether the angle θ of the device 8 is set to the initial value. If not set to the initial value, the angle θ of the device 8 is initialized in step S5. Set to the value,
Move to step S6. In this case, the CPU 1-1 sends the rotation angle data of the stepping motor 6 set as the initial value to the stepping motor interface 1-7, and the stepping motor interface 1
-7 operates the stepping motor 6 to set the angle θ of the device 8 to an initial value.

A method of "returning the angle θ of the device 8 to the state when the power is turned off" when the power is turned off in step S1 is also performed by the same control procedure as described above.

On the other hand, if the initial value is set in step S4, the process immediately proceeds to step S6, the CPU 1-1 instructs the pressure sensor interface 1-5 to sample the pressure value, and the pressure from the pressure sensor 3 is sent. Get the data. Then, the process proceeds to step S10, "previous pressure value"
The "current pressure value" is set to the variable "previous pressure value" in which is set, and it is checked in step S11 whether or not a predetermined time, for example, 0.05 seconds has elapsed since the last pressure sampling, and 0 Step S1 until .05 seconds elapse
Repeat the check of 1. When 0.05 seconds has elapsed in step S11, the process returns to step S1 and the same control operation as described above is continued until the power is turned off.

If the vehicle body is not stopped at step S3,
That is, when the automobile is running, the pressure is sampled in step S7. The sampling procedure is step S
This is done in the same manner as in the case of 6. Then, step S8
Then, the value obtained by subtracting the "previous pressure value" from the "current pressure value" is set to the variable "displacement value", and in the next step S9, the "displacement value" is multiplied by a known proportional constant. Data is sent to the stepping motor interface 1-7, and the stepping motor 6 rotates by an angle equal to the value of the data. Then, the process proceeds to step S10, and the subsequent processes are performed in the same manner as described above, and are continued until the power is turned off.

[Second Embodiment] Next, a second embodiment of the present invention will be described with reference to FIGS. In this embodiment, the same parts as those in the first embodiment described above will be described with the same reference numerals in the drawings.

In the first embodiment described above, the stepping motor 6 is forcibly used to swing the display computer device 8. However, this is not only mechanically complicated in design, but also the stepping motor 6 may not be able to follow as the frequency increases.

Therefore, in this embodiment, the device 8 itself is the vehicle body 1
It is fixed at 0, and the image itself displayed on the display unit 13 is electrically moved up and down in accordance with the up and down movement of the user. This eliminates the need for a mechanical operation part, which simplifies the mechanism and does not cause a problem in the followability of the stepping motor 6.

FIG. 5 is a diagram showing a screen display state on the display unit 13, 13-1 being a screen frame, 13-
Reference numeral 2 denotes a display area, and in some cases, the display area 13-2 moves up and down within the dotted line range 7-3 of the screen frame 13-1.

FIG. 6 is a schematic diagram showing an application example in which the information display device according to the present embodiment is mounted on an automobile. The present embodiment differs from the first embodiment described above in that the display computer device 8 having the display unit 13 is fixed to the vehicle body 11, and the vertical bias electrode 19 is set in the vertical direction of the electron gun 18 of the display unit 13. Has been done, controller 1
By applying the voltage specified by the above as the vertical bias voltage, the display area 13-2 on the display unit 13 is
Is to be able to move and display within the range 13-3 of the dotted line of the screen frame 13-1.

Further, in this case, since the pressure curve itself from the pressure sensor 3 can be used as the voltage curve of the vertical bias electrode 19, the controller 1 only needs to have a simple amplifier function. Become. That is, unlike the first embodiment, it is not necessary to digitally sample the pressure value and repeatedly calculate the displacement value that changes momentarily from the sampled value. Therefore, the controller 1 can be sufficiently realized by a simple analog circuit.

By performing the above processing, the program 56 is executed for each first line.

The processing of the program 56 is performed in the interpreter format in the same manner as the programming language "BASIC".
Since the line-by-line processing is executed, the program 56 does not need to perform compiling work, linking work, etc. before execution, unlike the programming language "C".

As described above, the check of a new window, the check of "character string" in a message, and the execution process after judgment of these checks are described in a simple program format and automatically performed. It can be used in various cases and can be used for general purposes.

Further, in this embodiment, the character recognition and various check judgments are started only when a new window is displayed. However, the application is not limited to the application in which the warning message is displayed on the new warning window 42 as shown in FIG. For example, a warning message may be displayed in the display area itself of the external device control window display 41, and in particular, a new warning window 42 may not be displayed as shown in FIG.

In such a case, New which monitors the appearance of a new window in the program 56 Wi
Check for checking whether or not there is a change in the display of the screen 40 by checking the VRAM 25-3 of FIG. 7 which stores the display data of the screen 40 instead of the ndown () function. VRAM A Change () function can also be provided. This function monitors the entire screen 40, and if any part of the display on the screen 40 has changed, it is set to true (TRUE), and the changed part of the screen 40 is recognized. , For example, the title 42-1, the warning message 42-2 and the character string 42-3 of the "continue acceleration" button display, the character string 42-4 of the "constant speed running" button display, and the character of the "fuel cut" display of FIG. It is stored as a column 42-5. In this case, New Check Window () function V

Next, the control operation of this embodiment will be described with reference to FIG.

FIG. 23 is a flow chart showing the control operation of the keyboard processing program of the information display device according to this embodiment.

This program starts up at the same time when the power is turned on, and thereafter, the processing is executed as a multitasking program in parallel with the OS and the street display program, and the key input to the keyboard 62 is monitored and the keyboard is displayed on the HMD 61. 82 is made.

First, in step S91, it is checked whether or not the power source is off. If the power source is off, the process returns to end the control operation. However, if the power is not off, it is checked in step S92 whether or not the user 67 has pushed the [AX] key.
Then, it is checked whether the keyboard display 82 is being displayed on the HMD 61.

If it is not being displayed, the keyboard display 82 is displayed on the HMD 61 (step S94). If it is being displayed, the keyboard display 82 is being displayed on the HMD 61.
Is erased (step S95), and the process returns to step S91.
That is, each time the user 67 presses the [AX] key on the keyboard 62, the keyboard display 82 appears or disappears on the HMD 61.

If the user 67 does not push the [AX] key in step S92, the flow advances to step S96 to check whether or not the user 67 has key-touched the key top 90. If the key is touched, it is checked in step S97 whether the keyboard display 82 is currently displayed on the HMD 61. If it is not being displayed, nothing is done and the process returns to step S91. If it is being displayed, in step S98, the key-touched key top in the keyboard display 82 is displayed with a low brightness key (for example, 82-1 in FIG. 21), and the process returns to step S91.

If the user 67 has not made a key touch in step S96, the process moves to step S99 and the user 67
Checks whether or not the key top 90 is key-pushed. If the key is pushed, it is checked in step S100 whether the keyboard display 82 is being displayed. If it is not being displayed, the process directly returns to step S91. If it is being displayed, in step S101, the key-pushed key top in the keyboard display 82 is displayed with a high-intensity key (for example, 82-2 in FIG. 21), and in step S102, the key code of this key top 90 is displayed in the computer main body. 60
To step S91.

If the user 67 does not key-push the key top 90 in step S99, step S9 is performed.
Return to 1.

As a result, the user can display the keyboard display 82.
You can key in while watching.

Since the display brightness of the key tops on the keyboard display 82 changes, the user can perform key input while checking which key is touched or pushed.

Keyboard display 82 on this HMD 61
Does not have to be continuously displayed, and the user 67 can press the [AX] key at the upper left corner of the keyboard 62 to
The keyboard display 82 on the MD 61 can be displayed or erased, and the user 67 can temporarily [AX].
If a special key such as a key can be completely blind-touched, the keyboard display 82 on the HMD 61 becomes unnecessary. This program of this embodiment is a program in which the keyboard display 82 can be erased and the key input from the keyboard 62 can be performed in the erased state.

In many cases, the HMD 61 has divided images for the left eye and the right eye, and displays the left eye image and the right eye image, respectively, so that the user 67 can stereoscopically view the images. There is. In such a case, the keyboard display 82 described above also creates a keyboard image viewed from the left-eye position and a keyboard image viewed from the right-eye position, and displays the left-eye image and the right-eye image, respectively, for stereoscopic viewing. become.

In this embodiment, the keyboard display 82 is also displayed.
Has been described as being fixedly displayed on the HMD 61 below. Therefore, since the user 67 turns his head, HMD
Even if the image of the street on 61 is changed to the image around the neck, the keyboard display 82 is always fixed and displayed below the HMD 61. For this reason, for example, when the user 67 turns his / her neck down, it is difficult to check the keyboard display 82 with his / her neck down. Therefore, it is necessary to check the keyboard display 82 on the HMD 61 with the eyes only facing downward while the face is facing the front. This is very annoying, so after the keyboard display 82 is also displayed on the HMD 61, the HMD
Think of it as an object in the virtual space displayed on 61,
It is preferable to change the display position of the keyboard display 82 according to the direction in which the user's neck is turned. That is, when the user 67 presses the [AX] key, the keyboard display 82 appears 1 m above the road surface of the street on the HMD 61, that is, in front of the user 67, and the user 67 puts his or her head down. When it is turned to, the keyboard display 82 is made to appear in the direction to look down on the front so that the keyboard display 82 can always be seen right in front.

For this purpose, when the user presses the [AX] key, the keyboard 6 is fixed in the street image.
Data may be created by regarding 2 as one object in the street image, and thereafter, the data may be displayed as a display object in the street image without being distinguished from other street data.

If the user 67 presses the [AX] key again,
The keyboard display 82 can be erased from the image on the street, and the display as an object fixed in this image can be canceled.

[Fifth Embodiment] Next, a fifth embodiment of the present invention will be described with reference to FIGS.

In the above-described fourth embodiment, the touch sensor 93 on the keyboard 62 is arranged on the key top 90.
A case has been described in which the two electrodes 93a ₁ and 93a ₂ are energized when the user's finger 97 touches them. In addition to this, a sensor for catching a change in capacitance when the user's 67 finger 97 touches, Alternatively, a touch sensor can be used by using a sensor or the like that catches a change in pressure or temperature.

In this embodiment, an example in which a keyboard is constituted by using a touch panel, a light emitting / receiving mat in which a light emitting element and a light receiving element are embedded will be described. In this case, the touch panel functions as a push sensor, and the light emitting / light receiving mat functions as a touch sensor.

FIG. 24 is a sectional view of the keyboard according to this embodiment.

As shown in the figure, this keyboard has the touch panel 100 as an upper surface, and the touch panel 100
The light-emitting / light-receiving mat 101 is provided on the lower surface at a certain distance S from. The touch panel 100 is a known transparent plate having a large number of pressure sensors (not shown) built therein. When the user strongly presses the finger 102 (hereinafter, referred to as “push”), the pressure sensor (not shown) is in the pushed state. To detect.

The light emitting / light receiving mat 101 is a plate in which a large number of light emitting elements 101a and light receiving elements 101b are embedded, and the light ray 103 emitted from the light emitting element 101a is
The surface of the transparent touch panel 101 is reflected at a certain angle, and a fixed amount of reflected light is received by the light receiving element 101b. However, when the user touches the surface of the touch panel 100 with the finger 102 (hereinafter referred to as “touch”), the refractive index of the surface of the touch panel 100 changes, and the light receiving element 10 is changed.
The amount of light entering 1b decreases. Therefore, the touch state is detected by the light emitting element 101a and the light receiving element 101b.

FIG. 25 is a diagram showing a signal path outputted from the keyboard of FIG. 24, and the same elements as those of FIG. 24 are designated by the same reference numerals.

The upper surface of the touch panel 100 is 100 in the figure.
Input keys (hereinafter simply referred to as “keys”) of known characters 0 to 9 and alphabets A to Z and [AX] such as a are displayed, and this touch panel 100 is for a touch panel. CPU 6 via arithmetic unit 104
4 is connected. Also, the light emitting / receiving mat 101
CPU6 via the light emitting / receiving mat computing unit 105.
4 is connected. Touch panel 100, light emitting / receiving mat 101, touch panel computing unit 104, and light emitting / receiving
All the light-receiving mat computing units 105 collectively form a keyboard. The keyboard in this case is a keyboard with a touch sensor and a push sensor.

Next, the calculator 10 for the light emitting / receiving mat is provided.
The control operation of No. 5 will be described with reference to FIG.

FIG. 26 is a flow chart showing the control procedure of the light emitting / light receiving mat computing unit 105 of FIG.

First, in step S110, the fact that all keys are in the untouched state is recorded. Then step S
If the power source is off in 111, the arithmetic unit 105 does not operate and does not perform the control operation. However, when the user touches the touch panel 100 with the finger 102 while the power source is in the on state, as described above, Due to the change, the light amount of the light ray 103 emitted from the light emitting element 101a of the light emitting / receiving mat 101 is reduced and is received by the light receiving element 101b. As a result, key input data capable of identifying which key the user is touching is obtained (step S11).
2). In the next step S113, the calculator 105 compares the key input data with each key data on the touch panel 100 built in the calculator 105 to detect which key the user is touching. Yes (step S114). Then, in comparison with the key data of the touch state recorded last time (step S115), the key code and the signal indicating the “touch state” of the key which is in the touch state for the first time are sent to the CPU 64 side. (Step S116) Further, for the key that has been in the untouched state for the first time this time, the key code and a signal indicating the "untouched state" are sent to the CPU 64 side (step S117). In the next step S118, the key data of the currently touched state is recorded, and the process returns to step S111. By repeating such control operation in a short time, the touch signal to the touch panel 100 is continuously CP.
It becomes possible to send to the U64 side.

On the other hand, with respect to the push signal to the touch panel 100, the touch panel computing unit 104 performs the same processing operation as the light emitting / receiving mat computing unit 105, so that the CPU 64 has a key code and a signal indicating the push state and the key code. And a signal indicating the Ampush state is sent. That is, push signals to the touch panel 100 are continuously sent to the CPU 64 side.
