Description

  The present invention relates to an electronic apparatus and a drawing operation method for detecting a position indicated using a pen-type position indicator.

  Conventionally, a pen tablet is known as an input device used for an electronic apparatus such as a personal computer. The applicant has so far proposed various pen tablets (see, for example, Patent Document 1).

  A typical pen tablet is composed of a pen-type position indicator and a substantially flat position detection device. The user holds the position indicator in his hand and indicates an arbitrary position on the position detection device. The detected position is detected by a position detection device, and the detected position is output to an externally connected electronic device.

Users can perform input operations to electronic devices by operating the position indicator as if drawing a character or picture with a pen. It has gained.
For example, when using an application program for drawing in an electronic device, when performing an operation for inputting a drawing position (hereinafter referred to as a drawing operation), using a pen tablet, the operation is similar to drawing a picture. Is very convenient.

JP 2002-244806 A

  By the way, while using an application program for drawing, in addition to the drawing operation, operations for performing various settings relating to drawing are essential. Examples of this type of operation include operations such as setting the drawing color, setting the size of the drawing area, setting the thickness of the line to be drawn, scrolling the screen and zooming in / out the screen.

  These operations are usually performed by calling a dedicated screen called a menu screen. In many cases, the user repeatedly performs an operation on the menu screen and a drawing operation alternately. However, in order to perform operations on the menu screen during the drawing operation, it is necessary to stop the movement of the hand holding the position indicator and move the position indicator to a position unrelated to the picture being drawn. There is a possibility that the user's thinking will be interrupted and the willingness to create will be lost. Further, for a user who wants to concentrate on the drawing operation, the operation on the menu screen is considered to be extremely complicated although it is a necessary operation.

  Accordingly, an object of the present invention is to perform operations such as setting the drawing color, setting the size of the drawing area, setting the thickness of the line to be drawn, scrolling the screen and zooming in / out the screen while using the position indicator. It is an object of the present invention to provide an input system that makes it easy and easy to perform.

In order to achieve the above object, in the present invention, an area for detecting an indicated position by operating a position indicator having a resonance circuit is set, and detection of an indicated position by operating the position indicator in this area is performed. , A detection signal of the indicated position by the operation of the position indicator detected by the position detection device performed by the electromagnetic transfer operation with the resonance circuit provided in the position indicator, and the touch pad unit for detecting the operation of the finger This is an electronic device to which a detection signal for finger operation is supplied.
In this electronic device, detection of finger operation on the touch pad unit is performed by a capacitance method, which is a method different from detection of an indicated position by operation of a position indicator having a resonance circuit that is performed by electromagnetic transmission and reception. Is called.

  In addition, the touch pad portion that detects the operation of the finger is disposed at either the inside or the outside of the region for detecting the indication position by the operation of the position indicator provided with the resonance circuit, or the position straddling the inside and the outside. Yes. In the electronic device, the display device further displays a drawing corresponding to the position indicated by the operation of the position indicator, and the drawing based on the operation of the position indicator based on the operation of the finger detected by the touch pad unit. In this case, at least one of zoom-in and zoom-out operations and scroll operations is performed.

The drawing operation method of the present invention includes the following steps (a) to (d).
(A) a step of setting a region for detecting a position indicated by an operation of a position indicator provided with a resonance circuit;
(B) a step of performing detection of the indicated position by operating the position indicator in this region by an electromagnetic transfer action with a resonance circuit provided in the position indicator;
(C) A touch pad unit for detecting the operation of the finger is disposed either inside or outside the region for detecting the position indicated by the operation of the position indicator provided with the resonance circuit, or at a position straddling the inside and the outside. The step of detecting the finger operation on the touch pad unit by a capacitance method, which is a method different from the detection of the indicated position by the operation of the position indicator provided with the resonance circuit that is performed by the electromagnetic transfer function. ,
(D) Display drawing according to the position indicated by the operation of the position indicator, and zoom in and zoom out with respect to the drawing by the operation of the position indicator based on the operation of the finger detected by the touch pad unit. Performing at least one of the operation and the scroll operation.

  As a preferred embodiment of the present invention, a zoom-in / zoom-out operation and a scroll operation are performed by a position indicator displayed on the display device based on a finger operation on the touch pad unit. Further, the touch pad unit detects a finger operation two-dimensionally.

According to the present invention, only an operation or a position by an object other than the position indicator (for example, a user's finger) at a position within or outside the effective area where the position indicated by the position indicator can be detected or across the inside or outside of the effective area. Both the operation by the indicator and the operation by an object other than the position indicator can be detected by the operation detection means.
Thereby, while performing a certain kind of operation using the position indicator, another kind of operation, that is, a zoom-in and zoom-out operation and a scroll operation can be performed.

Further, according to the present invention, while a drawing application program is being executed, a drawing line is drawn by operating a position indicator, a menu screen is called by operating the touch pad unit, an operation on the menu screen, zoom in / out is performed. , Operations such as screen scrolling can be performed.
Thus, since it becomes possible to perform another kind of operation, without interrupting the flow of operation using a position indicator, and a user's thought, very good operativity can be provided. Also, for example, when the user is operating with the position indicator in the right hand, it is possible to operate the touch pad portion with the left hand, and the touch pad portion is operated with the position indicator held in the right hand You can also That is, the user can freely perform input operations on electronic devices using both hands.

In addition, according to the present invention, various operations can be performed without interrupting or hindering the flow of operations by the position indicator, so that the operability is very good. Also, for example, when the user is operating with the position indicator in the right hand, it is possible to operate the touch pad portion with the left hand, and the touch pad portion is operated with the position indicator held in the right hand You can also
That is, the user can perform an input operation using both hands freely. In addition, since the touch pad unit detects operations by the position indicator, the user can operate the touch pad unit while holding the position indicator in his / her hand, and can perform various operations only with the position indicator. it can.

  In addition, when the position indicated by the position indicator in the effective area is detected by an electromagnetic transfer action with the position indicator, for example, a press detection type switch or the like is used in the touch pad unit. Can do.

  When the touch pad unit detects an operation by contact or pressing, the user can operate the touch pad unit by a very simple operation of touching or pressing the touch pad unit. For this reason, for example, even when the position indicator is operated with the dominant hand and the touchpad part is operated with the hand on the non-dominant hand, the operation can be performed without error, so that the user can maintain high operability while maintaining high operability. Can be reduced.

  In addition, the touch pad unit can detect both an operation by a position indicator and an operation by an object (finger) other than the position indicator, but if any operation on the touch pad unit is detected, the operation is performed. Can be determined whether the operation is performed by a position indicator or an operation (finger) other than the position indicator. Therefore, it is possible to perform a wide variety of input operations using the touch pad unit by distinguishing the operation by the position indicator and the operation by an object (finger) other than the position indicator as different operations.

  Further, the effective area and the area including the periphery of the effective area have a detectable area capable of detecting the position of the position indicator. A touch pad portion is provided in the detectable area. For this reason, it can be determined based on the position of the position indicator at the time of the operation whether the operation detected by the touch pad unit is an operation by the position indicator or an operation other than the position indicator (finger). This makes it possible to reliably determine whether the operation detected by the touch pad unit is an operation using the position indicator or an operation other than the position indicator (finger). Furthermore, since the detectable region does not need to coincide with the effective region, there is an advantage that the degree of freedom related to the arrangement of the touch pad portion is increased.

  It is also conceivable that the touch pad portion is disposed in the effective area. In this way, since the touch pad portion can be accommodated within the size of the effective area, it is possible to reduce the size of the position detection device itself.

It is an external view which shows schematic structure of the tablet 1 in embodiment of this invention. FIG. 2 is a partial perspective view illustrating in detail a configuration of a touch pad 131 illustrated in FIG. 1. It is a figure which shows the structure of the control circuit 200 incorporated in the tablet 1 shown in FIG. It is a figure which shows the arrangement | positioning state of the detectable areas 16 and 17 in the tablet 1 shown in FIG. 3 is a flowchart showing an example of operation when the tablet 1 shown in FIG. 1 is used as an input device of an electronic device 22. It is a figure which shows schematic structure of another example in embodiment of this invention. It is a figure which shows schematic structure of another example in embodiment of this invention.

The best mode for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 is an external view showing a schematic configuration of a tablet 1 as a specific example of the position detection device of the present invention. The tablet 1 is used in combination with an input pen 21 (FIG. 3) as a specific example of a position indicator. The tablet 1 is externally connected to an electronic device (FIG. 3) such as a personal computer.

As shown in FIG. 1, the tablet 1 includes a casing 11 that includes an effective area 12, touch pad units 13 and 14, and a pilot lamp 15.
The casing 11 is a substantially flat casing, is made of a synthetic resin or metal member, and incorporates a control circuit 200 (FIG. 3) and the like.

  The effective area 12 is a flat area disposed substantially at the center of the casing 11 and is an area where the position designated by the input pen 21 (FIG. 3) can be detected. In the effective area 12, an XY orthogonal coordinate system based on virtual X and Y axes is set, and the tablet 1 outputs an indication position by an input pen 21 (FIG. 3) described later as XY coordinates. To do. In the present embodiment, as an example, an X axis extending in the left-right direction in FIG. 1 and a Y axis extending in the up-down direction in FIG. 1 are set.

  The pilot lamp 15 is a lamp that is lit when the tablet 1 is connected to the electronic device 22 (FIG. 3) and is ready for use, and when an operation with the input pen 21 or the like is detected.

The touch pad unit 13 and the touch pad unit 14 are disposed on the left and right sides outside the effective area 12.
The touch pad unit 13 includes a touch pad 131 that detects a pressing operation by the user and a total of four switches 132, 133, 134, and 135. The touch pad 131 is an elongated rectangle, and detects a pressed position when pressed. The switches 132, 133, 134, and 135 are each formed in a rectangular shape having the same or different size, and are turned on when a pressing operation is performed.
The switches 132, 133, 134, and 135 may have any shape, and may be round or square.

  FIG. 2 is a partial perspective view showing a schematic configuration of the touch pad 131. As shown in FIG. 2, a plurality of press detection switches 136 are arranged along the longitudinal direction of the touch pad 131, and the plurality of press detection switches 136 are switches that are turned on when pressed. Here, the longitudinal direction of the touch pad 131 is referred to as an “axis” indicated by an arrow in the drawing. In the present embodiment, the axis of the touch pad 131 is parallel to the Y axis of the effective area 12.

  The tablet 1 can detect the pressing position in the axial direction by specifying the pressing detection switch 136 that is turned on among the plurality of pressing detection switches 136 disposed on the touch pad 131. The tablet 1 can also determine that the position between these press detection switches 136 has been pressed, for example, when adjacent press detection switches 136 detect pressing operations simultaneously. Thereby, the tablet 1 can detect the pressing operation at the position of the pressing detection switch 136 on the touch pad 131 and the position between the pressing detection switches 136. Therefore, for example, as shown in the example shown in FIG. 2, when seven touch detection switches 136 are provided on the touch pad 131, the positions of the seven pressure detection switches 136 and the positions between the pressure detection switches 136 correspond to each other. It is possible to detect pressing operations at a total of 13 locations including the 6 locations (symbol A in the figure).

  Here, the configuration of the touch pad 131 has been described with reference to FIG. 2, but since the touch pad 141 is configured in the same manner as the touch pad 131, illustration and description regarding the touch pad 141 are omitted.

  FIG. 3 is a block diagram showing a configuration of the control circuit 200 built in the tablet 1. 3 includes a control unit 201, a transmission / reception unit 202, a selection circuit unit 203, a selection circuit unit 204, a loop coil 205, and a loop coil 206. The control unit 201 includes touch pads 131 and 141 and a switch 132. , 133, 134, 135, 142, 143, 144, 145 are respectively connected.

  3 also shows an electronic device 22 that is externally connected to the tablet 1, and a display device 23 and an output device 24 that the electronic device 22 has. An input pen 21 used in combination with the tablet 1 is also illustrated. The input system 100 is configured by the input pen 21, the electronic device 22, and the tablet 1.

  The loop coils 205 and 206 of the control circuit 200 are disposed immediately below the effective area 12 (FIG. 1) of the tablet 1. The loop coil 205 is a loop coil having a linear portion extending in the Y-axis direction of the effective area 12. Immediately below the effective area 12, a plurality of loop coils 205 are arranged side by side along the X-axis direction so as to be shifted by a predetermined distance. Further, the loop coil 206 is a loop coil having a linear portion extending along the X-axis direction of the effective area 12. Immediately below the effective area 12, a plurality of loop coils 206 are arranged side by side so as to be shifted by a predetermined distance along the Y-axis direction.

A transmission / reception unit 202 is connected to the control unit 201, and all loop coils 205 are connected to the transmission / reception unit 202 via a selection circuit unit 203 and all loop coils 206 are connected to each other via a selection circuit unit 204. Is done. The selection circuit unit 203 has a function of selecting one loop coil 205 from among the plurality of loop coils 205, and the selection circuit unit 204 has a function of selecting one loop coil 206 from among the plurality of loop coils 206. Have
Although details will be described later, the control unit 201 performs a transmission / reception operation by the transmission / reception unit 202 while selecting the loop coil 205 by the selection circuit unit 203, whereby the indicated position instructed by the input pen 21 in the X-axis direction. Get the position (X coordinate). In addition, the control unit 201 executes the transmission / reception operation by the transmission / reception unit 202 while selecting the loop coil 206 by the selection circuit unit 204, whereby the position in the Y-axis direction (Y coordinate) indicated by the input pen 21 is performed. ) To get.

Note that the loop coils 205 and 206 are not arranged just below the effective area 12, but actually have a structure in which a part protrudes from directly below the effective area 12. This is because the specified position in the effective area 12 can be accurately and reliably detected by providing a margin for mounting, and a part of the design area can be freely projected from directly below the effective area 12. This is because it has the advantage of increasing.
Therefore, the area where the position of the input pen 21 can be detected in the tablet 1 is an area wider than the effective area 12 including the effective area 12 and the periphery of the effective area 12. This area is called a detectable area.

FIG. 4 is a diagram illustrating an arrangement state of the detectable areas in the tablet 1.
The loop coils 205 arranged side by side in the X-axis direction of the effective area 12 reach the outside of the effective area 12 in the vertical direction (that is, the Y-axis direction) in FIG. A region (broken line in the figure) corresponding to the position directly above the loop coil 205 is a detectable area 16.
Further, the loop coils 206 arranged side by side in the Y-axis direction of the effective area 12 reach the outside of the effective area 12 in the left-right direction in FIG. 4 (that is, the X-axis direction). A region (broken line in the figure) corresponding to a position directly above the loop coil 206 is defined as a detectable area 17.

  The detectable area 16 is directly above the loop coil 205 extending in the Y-axis direction. Therefore, when the position is instructed by the input pen 21, the tablet 1 can acquire at least the X coordinate in the detectable area 16. Similarly, since the detectable area 17 is directly above the loop coil 206 extending in the X-axis direction, the tablet 1 acquires at least the Y coordinate in the detectable area 17 when the position is instructed by the input pen 21. Is possible. Of course, in the effective area 12, the tablet 1 can acquire both the X coordinate and the Y coordinate of the input pen 21.

Returning to FIG. 3, the control unit 201 included in the control circuit 200 is externally connected to the electronic device 22. The electronic device 22 is a device such as a personal computer or a PDA (Personal Digital Assistance), and includes a display device 23, an output device 24, and the like. The display device 23 includes a screen such as a CRT (Cathode Ray Tube) or an LCD (liquid crystal display), and the output device 24 is a device such as a printer.
The electronic device 22 can execute various application programs, accepts signals output from the control circuit 200 and operates the application program. For example, the display on the screen of the display device 23 can be scrolled, zoomed in / out, etc. Processing is performed, or functions such as copying, cutting and pasting in the application program are executed.

As described above, the input pen 21 is combined with the tablet 1 (FIG. 1) incorporating the control circuit 200. The input pen 21 is a position indicator in which a resonance circuit 211 is built in a pen-shaped casing, and is used by the user holding it.
The resonance circuit 211 includes a capacitor 212 and a coil 213, generates an induced current by a radio wave having a predetermined frequency, and operates based on the induced current to transmit a radio wave having a predetermined frequency. The coil 213 is connected to a writing pressure detection mechanism (not shown) of the input pen 21. When an operation of pressing the pen tip of the input pen 21 is performed, the coil 213 is changed according to the writing pressure applied by the operation. The inductance changes, and the resonance frequency of the resonance circuit 211 changes.

The control unit 201 controls the transmission / reception unit 202 to acquire the coordinates of the position designated by the input pen 21 and output the coordinates to the electronic device 22.
That is, the transmission / reception unit 202 operates the selection circuit unit 203 under the control of the control unit 201 to select one loop coil 205 from among the plurality of loop coils 205 arranged in the X-axis direction, and selects the selected loop coil 205. When a radio wave is transmitted from the input pen 21 by an induced current generated in the resonance circuit 211 of the input pen 21 by the radio wave, an operation of receiving the radio wave is performed. The transmission / reception unit 202 detects the position of the input pen 21 in the X-axis direction by repeatedly executing the above operation while sequentially switching and selecting the plurality of loop coils 205 by the selection circuit unit 203. Also, the transmission / reception unit 202 operates the selection circuit unit 204 under the control of the control unit 201 to select one loop coil 206 from among the plurality of loop coils 206 arranged in the Y-axis direction, and the selected loop coil 206 is selected. Transmits radio waves of a predetermined frequency. When a radio wave is transmitted from the input pen 21 by an induced current generated in the resonance circuit 211 of the input pen 21 by the radio wave, an operation of receiving the radio wave is performed. The transmission / reception unit 202 detects the position of the input pen 21 in the Y-axis direction by repeatedly executing the above operation while sequentially switching and selecting the plurality of loop coils 206 by the selection circuit unit 204.

Thereafter, the control unit 201 outputs the positions in the X-axis direction and the Y-axis direction obtained by the operation of the transmission / reception unit 202 to the electronic device 22 as XY coordinates.
Further, the control unit 201 controls the transmission / reception unit 202 to analyze the radio wave transmitted from the input pen 21 and detect a change in the resonance frequency of the resonance circuit 211 included in the input pen 21, whereby the input pen 21. The pressing operation at is detected.

  In addition, when the touch pad 131 or 141 is operated, the control unit 201 acquires an operation position based on a signal input from the touch pad 131 or 141, and the operation is performed by the input pen 21 or It is determined whether the operation is performed by an object other than the input pen 21 (for example, the user's finger), and a signal indicating the determination result and the operation position is generated and output to the electronic device 22.

  Further, when the switch 132, 133, 134, 135, 142, 143, 144, 145 detects a pressing operation (when turned on), the control unit 201 is based on a signal input from the switch. A signal indicating the pressed switch is generated and output to the electronic device 22.

The tablet 1 configured as described above constitutes the input system 100 (FIG. 3) together with the electronic device 22 and can be used as an input device of the electronic device 22.
Here, an example of an operation when the tablet 1 is used as an input device of the electronic device 22 will be described with reference to a flowchart of FIG.

5 may be realized by the function of the control unit 201 of the tablet 1 or may be realized by executing a program such as a device driver program in the electronic device 22 to which the tablet 1 is connected. May be.
Here, as an example, a case where the operation is realized by the function of the control unit 201 built in the tablet 1 will be described.

The operation shown in FIG. 5 is an operation for responding to the operation when the operation on the touch pads 131 and 141 is detected.
First, when the control unit 201 detects an operation in any one of the touch pad units 13 and 14 based on a signal input from either the touch pad 131 or 132 (step S11), the detected operation is detected by the input pen 21. Or an operation with an object other than the input pen 21 (for example, a user's finger) is determined (step S12). As described above, this determination can be performed by comparing the operation position on the operated touch pads 131 and 141 with the position of the input pen 21 detected using the loop coils 205 and 206. For example, when the control unit 201 detects an operation on the touch pads 131 and 141, the position of the input pen 21 detected by the loop coils 205 and 206 is outside the effective area 12, and the input pen 21 When the pressing operation is performed, it is determined that the touch pads 131 and 141 are operated by the input pen 21.

Here, when the detected operation is an operation with an object other than the input pen 21, the control unit 201 acquires the operation position on the touch pads 131 and 141 (step S13).
Then, the control unit 201 determines whether or not the detected operation is a continuous operation (step S14). That is, the control unit 201 acquires the elapsed time from the previously detected operation to the current operation on the side of the touchpads 131 and 141 that detected the current operation, and the same side within the predetermined time from the previous operation. A case where the touch pad is operated is determined as a continuous operation.

  If the control unit 201 determines that the operation is not a continuous operation (step S14; No), it recognizes the operation detected in step S11 as a single switch operation, generates a signal indicating the operation, and outputs the signal to the electronic device 22. (Step S15).

  If it is determined in step S14 that the operation is a continuous operation, the control unit 201 performs a pulse count (step S16). This pulse count is a process of counting the number of times of continuous operation and holding the operation position of each operation temporarily when a continuous operation is performed. The control unit 201 counts the count value. Then, a signal indicating the operation position of each operation is generated and output to the electronic device 22.

  On the other hand, if it is determined in step S12 that the operation detected in step S11 is an operation with the input pen 21, the control unit 201 acquires the operation positions on the touch pads 131 and 141 (step S17). Then, the control unit 201 determines whether or not the detected operation is a continuous operation (step S18). If it is determined that the detected operation is not a continuous operation, the operation detected in step S11 is recognized as a single switch operation. Then, a signal indicating the operation is generated and output to the electronic device 22 (step S19).

  If it is determined in step S18 that the operation is a continuous operation, the control unit 201 performs a pulse count, generates a count value and a signal indicating the counted operation position of each operation, and outputs the signal to the electronic device 22 ( Step S20).

  In addition, what kind of operation | movement should be performed in the electronic device 22 based on the signal output to the electronic device 22 from the tablet 1 by the operation | movement shown in FIG. 5 should just be preset, and is not restrict | limited at all. That is, the operations on the switches 132, 133, 134, 135, 142, 143, 144, and 145 included in the touchpad units 13 and 14 can be assigned to various operations on the menu screen of a certain application program. It is also possible to assign the operation to screen scrolling and zoom in / out on the display device 23. Thus, the specific operation realized in the electronic device 22 can be arbitrarily determined by the user, and the present invention is not limited in this respect.

As described above, according to the tablet 1 in the embodiment of the present invention, the tablet 1 having the effective area 12 operated by the pen-type input pen 21 can be operated by an object other than the input pen 21 and the input pen 21. Since the touchpad units 13 and 14 are provided, another operation can be performed simultaneously while performing an operation using the input pen 21.
For example, when the user is operating with the input pen 21 in the right hand, the touch pad unit 14 can be operated with the left hand, and the touch pad units 13 and 14 can be operated with the input pen 21 held in the right hand. Can also be operated.

  Thereby, while performing a certain kind of operation using the input pen 21, another kind of operation can be performed in the touchpad units 13 and 14. For example, while a drawing application program is being executed in the electronic device 22, a drawing line is drawn by operating the input pen 21, a menu screen is called by operating the touch pad units 13, 14, operations on the menu screen, zooming in / out , Operations such as screen scrolling can be performed. In this way, since it is possible to perform different types of operations without interrupting the flow of operations using the input pen 21 and the user's thinking, it provides extremely good operability that is completely different from the prior art. can do.

  Further, when the operation on the touch pad units 13 and 14 is performed, it is possible to determine whether the operation is an operation with the input pen 21 or an operation with an object other than the input pen 21, so that the touch pad 131 can be distinguished. A case where the operation is performed with the input pen 21 and a case where the user operates with a finger can be distinguished, and different functions and operations in the electronic device 22 can be respectively assigned. As a result, the touchpad units 13 and 14 can instruct the touchpad units 13 and 14 to have functions far exceeding the number of touchpads and all the switches included in the touchpad units 13 and 14. That is, since various operations can be performed by the touch pad units 13 and 14, it can be used as an input device rich in utilities.

Furthermore, since the touch pad portions 13 and 14 are respectively arranged on the left and right sides of the effective area 12, the user can effectively use the right hand and the left hand to perform an appropriate input operation quickly. For example, a right-handed user has the input pen 21 in the right hand. In this case, if the touchpad unit 14 is operated with the left hand, the input operation can be easily performed with both hands. If the user is left-handed, the user can perform the same operation by holding the input pen 21 in the left hand and operating the touchpad unit 13 with the right hand. Therefore, the user can perform an input operation while freely using both hands, and can realize extremely good operability.
Further, the switches 132, 133, 134, 135, 142, 143, 144, and 145 are all switches having a simple configuration. Therefore, even if it is operated with the hand that is not the dominant hand, an operation error is not induced, and good operability can be ensured. Further, if a specific operation in the electronic device 22 is assigned to each of the switches 132, 133, 134, 135, 142, 143, 144, and 145, there is an advantage that various operations can be executed only by the touch pad units 13 and 14. is there.

  Further, as described with reference to FIG. 2, the touch pads 131 and 141 are configured to include a plurality of press detection switches 136, so that the user's operation can be reliably detected and can be realized at low cost.

In the above-described embodiment, the touch pads 131 and 141 have been described as having a plurality of press detection switches. However, the embodiment of the present invention is not limited to this, and for example, a capacitive method It is also possible to use a touchpad. In this case, not only the pressing operation by the user but also the contact operation can be detected. Note that even when the pressure detection switch is configured to detect a very small pressing force, there is an advantage that a contact operation (including a pressing operation that applies a very small pressing force) by the user can be detected. Further, the positions of the touch pad portions 13 and 14 are arbitrary, and may be arranged at a height position aligned with the lower end of the effective area 12, for example.
Further, the configuration of the touch pad units 13 and 14 is not limited to one having only one direction as described above, but has a structure having two or more axes and capable of detecting the operation position two-dimensionally. Also good. This case will be described with reference to FIGS. 6 and 7 as another example in the best embodiment to which the present invention is applied.
6 and 7, the same components as those of the tablet 1 shown in FIGS. 1 to 5 are denoted by the same reference numerals and description thereof is omitted.

FIG. 6 shows a schematic configuration of the tablet 3 having touch pads 33 and 34 instead of the touch pad portions 13 and 14.
The tablet 3 has a configuration in which touch pads 33 and 34 are disposed on both sides of the effective area 12. The touch pads 33 and 34 are respectively located outside the effective area 12 and inside the detectable area 17.
Each of the touch pads 33 and 34 has a rectangular shape and is wider than the touch pad 131 (FIG. 2) described above. The touch pads 33 and 34 can detect the operation position two-dimensionally during the pressing operation. That is, the position in the horizontal direction and the position in the vertical direction of the operation position can be specified.
Such a configuration can be realized, for example, by arranging the pressure detection switches 136 shown in FIG. 2 in a matrix in the touch pads 33 and 34, or by using a pressure sensitive film or the like.

  In the tablet 3 shown in FIG. 6, the touch pads 33 and 34 can be operated while operating the input pen 21 similarly to the configuration of the tablet 1 described above, and thus various effects similar to those of the tablet 1 can be obtained. .

  Furthermore, since the touchpads 33 and 34 can detect the operation position two-dimensionally together with the presence or absence of the operation, various input operations can be performed by a simple operation. For example, if the operation of moving the finger or the input pen 21 on the touch pads 33 and 34 in a specific direction is set in association with the movement direction and the operation of the electronic device 22, When the input pen 21 is moved, the screen of the display device 23 is scrolled in the electronic device 22, and when the finger or the input pen 21 is moved in the horizontal direction, the screen of the display device 23 is zoomed in / out on the electronic device 22. Operation such as performing can be realized. Thereby, it can utilize as an input device with high operativity.

FIG. 7 shows a schematic configuration of the tablet 4 having touch pads 43 and 44 instead of the touch pad portions 13 and 14.
The touch pads 43 and 44 are configured in the same manner as the touch pads 33 and 34 (FIG. 6) described above, and can detect an operation position two-dimensionally during a pressing operation.
The tablet 4 includes touch pads 43 and 44 on both sides in the effective area 12.

  In the tablet 3 shown in FIG. 6, the touch pads 43 and 44 can be operated while operating the input pen 21 similarly to the configuration of the tablets 1 and 3 described above, and thus various effects similar to those of the tablet 1 can be obtained. can get.

  Furthermore, since the touch pads 43 and 44 are disposed inside the effective area 12, there is an advantage that the overall outer dimensions of the tablet 4 can be reduced. That is, unlike the tablet 1 (FIG. 1) and the tablet 3 (FIG. 6), the detectable areas 16 and 17 are not utilized. If it is the size of the grade which gave it.

In the tablet 4, when the touch pads 43 and 44 detect a pressing operation, it is possible to distinguish whether the operation is performed by the input pen 21 or by an object other than the input pen 21.
For this reason, for example, it is possible to accept only an operation with an object other than the input pen 21 on the touch pads 43 and 44 and ignore the operation with the input pen 21. In this case, when the input pen 21 is moved within the effective area 12 and the operation is performed, the operation can be continued without any problem even if the input pen 21 overlaps the touch pads 43 and 44. Only when the touchpads 43 and 44 are operated with an object (such as a user's finger), another type of operation can be performed. Thereby, the tablet which can make size reduction and the improvement of operativity compatible is realizable.

In addition, in the said embodiment, about the detailed structures, such as the shape of the housing | casing 11, the touchpad parts 13 and 14, and the touchpads 33, 34, 43, and 44, it can change arbitrarily.
Further, the positions of the touch pad portions 13 and 14 and the touch pads 33, 34, 43, and 44 are not particularly limited, and may be disposed outside or inside the effective area 12 as described above. You may arrange | position in the position straddling 12 inside and outside.
The above description is merely an example when the present invention is applied, and is not intended to limit the technical scope of the present invention.
