Description

Panel type input device and elevator using same

Technical Field

The present invention relates to a panel-type input device that is input by an operation of an operator's hand, and an elevator using the panel-type input device.

Background

In a panel-type input device that inputs an input by an operation of an operator's hand, a desired input signal is input by touching or bringing a finger close to a display panel surface. However, in such a panel-type input device, a region from the wrist to the fingertip may come into surface contact with or approach the display panel, and a plurality of input signals may be input. Therefore, there is a phenomenon that an erroneous input signal is input to an original instruction.

In order to avoid such input of a plurality of input signals including erroneous input signals from the display panel surface, for example, japanese patent application laid-open publication No. 2011-134069 (patent document 1) shows the following panel-type input device.

In patent document 1, an object region predicted to have a touch operation is extracted, it is determined which object is the object region based on which object the extracted object region is, validity of the object region to which an attribute of a finger is given is determined based on an appearance state of the object region to which an attribute of a finger existing around the object region to which an attribute other than the finger is given is determined, and when it is determined that the object region is invalid, the object region is excluded from objects detected by a touch position, thereby obtaining an accurate input signal.

However, for example, in an elevator, a panel-type input device for hall call for registering a hall call is provided in a hall, or a panel-type input device for registering a destination floor is provided in an elevator car. These panel-type input devices are provided with hall call buttons and destination floor buttons. In addition, as the button, a contact type or a non-contact type button is used.

In such a panel-type input device, a plurality of input signals may be input by the area between the wrist and the fingertip coming into contact with or coming close to the display panel surface. Therefore, there is a phenomenon that an original instruction is input with an erroneous instruction. This phenomenon will be briefly described with reference to fig. 9.

Fig. 9 shows a state in which a panel-type input device for registering a destination floor provided in an elevator car is operated by a passenger.

In fig. 9, the panel-type input device 50 for registering a destination floor includes a rectangular display panel surface 60 for input on the front surface, and a plurality of input units (destination floor registration buttons and the like) 70 are arranged on the display panel surface 60.

In addition, although a passenger riding on the elevator car designates any one of the input units 70 of the display panel 60 in order to register a destination floor to be traveled to, in this case, a region (Hnd) from the wrist to the fingertip of the passenger overlaps with the plurality of input units 70, and an input signal of the destination floor may be unintentionally inputted from the plurality of input units 70.

Therefore, there is a phenomenon that an erroneous destination floor is input to the original destination floor. In particular, in the non-contact type button, since a region (Hnd) from the wrist to the fingertip is close to the detection space, there is a tendency that an erroneous signal is input. In addition, this phenomenon occurs even in a touch button.

In order to solve such a problem, for example, when the panel-type input device described in patent document 1 is used, many detection switches are required to determine the validity of the attribute of the target region, and the control software becomes complicated.

Disclosure of Invention

Therefore, there is a demand for a panel-type input device capable of specifying the most likely input unit even if input signals are unintentionally input from a plurality of input units with a simple system configuration without using a complicated detection mechanism or control software.

The present invention provides a panel-type input device capable of specifying a most likely input unit even if input signals are unintentionally input from a plurality of input units with a simple system configuration.

The present invention is a panel-type input device for inputting an input signal from an input unit on a display panel surface by an operation of an operator, the panel-type input device including a plurality of input units to which position coordinates are given on the display panel surface, and a control means for evaluating a relationship between the position coordinates of the plurality of input units to be input when an input signal is input from a plurality of input units smaller than the number of the plurality of input units, and determining an input unit of the most likely 1 position coordinate as a true input unit.

The effects of the present invention are as follows.

Thus, it is possible to provide a panel-type input device capable of specifying the most likely input unit even if input signals are unintentionally input from a plurality of input units with a simple system configuration.

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the drawings, but the present invention is not limited to the embodiments below, and various modifications and application examples are included within the scope of the technical concept of the present invention.

Fig. 1 shows a front view and a side view of a panel-type input device 10 according to an embodiment of the present invention. The panel-type input device 10 includes a display panel surface 11 on the front surface, and a plurality of input units 12 are provided on the display panel surface 11. The input unit 12 is in the form of a button in appearance, and is arranged in 4 rows and 3 columns.

The input unit 12 may be a contact type or a non-contact type. A known switch mechanism having a contact point can be used for the contact type, and a known switch mechanism such as an optical type or a capacitance type can be used for the non-contact type.

In the present embodiment, the non-contact input unit 12 is used, and the detection area 13 is set to a predetermined distance (D) from the surface of the display panel surface 11. Therefore, when the finger of the operator enters the detection area 13 and approaches any one of the input units 12, the input signal of the input unit 12 to which the finger approaches is detected.

In the present embodiment, position coordinates (application rectangular coordinates) are given to each input unit 12 on the display panel surface 11 in accordance with the mounting state of the panel-type input device 10 (which will be described later). The position coordinates may be regarded as position information of the input unit 12 on the display panel surface 11.

For example, in the illustrated embodiment of fig. 1, when the coordinates of the panel simplified for explanation are arranged so as to correspond to the position of the input unit (button), the input unit "0" in fig. 1 is the origin, the horizontal direction is defined as the "X axis", and the vertical direction is defined as the "Y axis", the input unit "0" is the position coordinates (0, 0), the input unit "E" is the position coordinates (1, 0), the input unit "C" is the position coordinates (2, 0), the input unit "7" is the position coordinates (0, 1), the input unit "8" is the position coordinates (1, 1), the input unit "9" is the position coordinates (2, 1), the input unit "4" is the position coordinates (0, 2), the input unit "5" is the position coordinates (1, 2), the input unit "6" is the position coordinates (2, 2), the input unit "1" is the position coordinates (0, 3), the input unit "2" is the position coordinates (1, 3), and the input unit "3" is the position coordinates (2, 3).

These input units 12 are stored in the storage unit of the control unit in association with their respective position coordinates. Therefore, for example, if "1" of the input unit 12 is instructed, the position coordinates (0, 3) corresponding to "1" are specified and read out. Of course, when an input signal is generated at a plurality of input units 12, the position coordinates of the corresponding input unit 12 are read. Hereinafter, the input units "2", "6", "7", and "8" in fig. 1 will be described as the plurality of input units 12 generated by the operation of the hand of the operator.

As described above, when an input signal is generated in a plurality of input units 12, the position coordinates of the corresponding input unit 12 are read, but in the present embodiment, the relationship between the plurality of position coordinates is evaluated, and the input signal of the input unit 12 of the most likely 1 position coordinate is determined as a true input signal.

The relationship of the position coordinates is determined based on at least the attachment state of the panel-type input device 10 and the direction of the fingertip of the operator with respect to the panel-type input device 10 in the normal operation of the operator.

For example, if the panel-type input device 10 is attached to a wall surface extending in a vertical direction from the ground surface, the input unit 12 to be targeted is pointed by a fingertip in a normal operation, and therefore the fingertip is positioned on the upper side and the palm (palm) is positioned on the lower side.

Therefore, when an input signal is generated at a plurality of input units 12, a plurality of position coordinates of the corresponding input unit 12 are read, but in the present embodiment, the maximum position coordinate in the Y-axis direction (upper side) is the most likely position coordinate, and is determined as the true input unit. The relationship is selected from various different conditions depending on the mounting state of the panel-type input device 10. This will be described later.

Next, a control unit of the panel-type input device 10 will be briefly described with reference to fig. 2. The control unit may be integrally formed with the panel-type input device 10, or may be provided in a control device different from the panel-type input device 10 and connected wirelessly or preferentially.

The control unit 15 is mainly constituted by a microcomputer. The display panel surface 11 is connected to an input detector 16, and has a function of detecting an input signal input by an operator. The input signal detected by the input detector 16 is processed by the input processing unit 17.

The input processing unit 17 executes arithmetic processing for specifying the true input signal as described above when there are a plurality of input signals and whether there are a plurality of input signals. In order to perform this arithmetic processing, the control unit 15 further includes a mounting state storage unit 18 and an input unit coordinate storage unit 19. The mounting state storage unit 18 stores "state information" indicating where the panel-type input device 10 is mounted in what state. The evaluation of the positional information of the input unit 12 can be changed by this "state information". As described above, the input coordinate storage unit 19 stores the position coordinates of the input unit 12 on the display panel surface 11.

Therefore, the input processing unit 17 can specify the most likely position coordinates by using the "state information" of the attachment state storage unit 18 and the position coordinates corresponding to the input unit 12. A specific method thereof will be described with reference to fig. 3 to 6.

The input signal of the input unit 12 determined by the arithmetic processing of the input processing unit 17 is transmitted from the input/output unit 20 to another control device or a display device, and necessary processing is executed. For example, when the panel-type input device 10 is installed in an elevator car of an elevator, the input/output unit 20 outputs a destination floor, and the output is transmitted to a supervisory control device of the elevator. The management control device causes the elevator car to move to the destination floor based on the destination floor sent from the elevator car.

Next, a specific example of the embodiment will be described with reference to fig. 3 to 6. This specific example shows an example in which the panel-type input device 10 is used for an elevator.

The elevator comprises a plurality of elevator cars and a waiting hall where the elevator cars stop, wherein a panel type input device for registering destination floors is arranged on the wall surface in the elevator cars, and/or a panel type input device for registering the calling of the waiting hall of the elevator cars is arranged on the wall surface of the waiting hall. In the present embodiment, a case where the panel-type input device is provided in an elevator car of an elevator is taken as an example.

Fig. 3 shows an internal structure of an elevator car 30 constituting an elevator. The elevator car 30 includes a floor surface wall 30FL, a rear surface wall (not shown) extending vertically upward from the floor surface wall 30FL, a right side wall 30RS and a left side wall 30LS extending vertically upward from the floor surface wall 30FL and adjacent to the rear surface wall, a front surface wall 30FR disposed adjacent to and between the right side wall 30RS and the left side wall 30LS so as to face the rear surface wall, and a ceiling wall 30CE covering the rear surface wall, the side wall 30RS, the left side wall 30LS, and the front surface wall 30FR from above. The adjacent wall surfaces of the elevator car 30 are connected in a vertical relationship, and have a rectangular tubular shape.

A sliding type opening/closing door 31 for allowing passengers to enter and exit is provided at the center of the front wall FR. When the opening/closing door 31 is opened, passengers get in and out for getting on or off the elevator, and the door is closed at the time of departure.

A panel-type input device 10 for registering a destination floor is attached to the front wall 30FR between the opening/closing door 31 and the right side wall 30 RS. The panel-type input device 10 for registering a destination floor can be attached to the front wall 30FR between the opening/closing door 31 and the left side wall 30 LS. The panel-type input device 10 has the same configuration as the panel-type input device shown in fig. 1, and has a display panel surface 11 formed in a rectangular shape, and input units 12 arranged in 4 rows and 3 columns.

As described with reference to fig. 1, the input units 12 are each provided with a position coordinate for each input unit 12. As described above, each input section 12 is associated with position coordinates, which are stored in the input coordinate storage section 19 of the control unit 15.

Regarding the mounting state of the panel-type input device 10, the display panel surface 11 is disposed so as to extend in the vertical direction along the front wall FR, and the display panel surface 11 is disposed so as to extend in the direction of the right side wall RS along the front wall FR, and "state information" indicating this is stored in the mounting state storage unit 18 of the control unit 15. The "state information" is an important parameter for determining the relationship of the position coordinates.

That is, the upper side (upper side on the Y axis) of the display panel surface 11 is a region where the tip of the operator's finger is located in normal operation, and the right side (right side on the X axis) of the display panel surface 11 is a region where the tip of the finger is located by the operator's hand passing through the left side on the side of the opening/closing door 31. In addition, since the right side wall 30RS is present, the hand of the operator does not extend from the right side. Therefore, the position coordinates of the input unit 12 in the region where the possibility that the tip of the finger is located is high can be regarded as the most likely position coordinates. Therefore, the further from the origin on the Y axis and the X axis, the greater the likelihood.

In this way, the position coordinates of the plurality of input units 12 can be evaluated by referring to the "state information" in the logic operation of the microcomputer. Here, the lower side or the left side of the display panel surface 11 is not operated with a palm (palm), and only fingers are likely to be present, so that there is little possibility of generating input signals for the plurality of input units 12. Therefore, even if the above setting is performed, the control logic is established. The same applies to the case where the panel-type input device 10 is attached to the left side of the opening/closing door 31.

In accordance with the above-described concept, the control process executed by the input processing unit 17 of the panel-type input device 10 will be described with reference to the flowcharts shown in fig. 4 to 6. Fig. 4 shows a control flow including the operation of an elevator, fig. 5 shows a detailed control flow of the "input point detection process" in fig. 4, and fig. 6 shows a detailed control flow of the "input point selection process" in fig. 4.

Step S10

In step S10, the mounting state of the panel type input device 10 is acquired. When the panel-type input device 10 is installed in the elevator car of an elevator, the installation state is registered in advance as "state information" in the installation state storage unit 18 of the control unit 15. Therefore, when the elevator is operated, the mounting state of the panel-type input device 10 is acquired in order to evaluate the position coordinates of the input unit 12 of the panel-type input device 10. When step S10 is completed, the process proceeds to step S11.

The "state information" includes at least information indicating whether the panel-type input device 10 is provided on the left side or the right side of the entrance, and may include information relating to the height of installation. By using the "state information", the panel-type input device disposed on the left side of the entrance and the panel-type input device disposed on the right side can be shared.

Step S11

In step S11, the coordinates of the input unit 12 are set. In this step, the position coordinates of the input unit 12 shown in fig. 1 are set in the X-axis direction and the Y-axis direction based on the above-described "state information". That is, the upward direction is set as the Y-axis direction, the direction from the opening/closing door 31 to the right side wall 32RS is set as the X-axis direction, in the illustrated embodiment of fig. 1, "0" of the arabic numeral is set as the origin, the input portion "0" is set as the position coordinates (0, 0), the input portion "E" is set as the position coordinates (1, 0), the input portion "C" is set as the position coordinates (2, 0), the input portion "7" is set as the position coordinates (0, 1), the input portion "8" is set as the position coordinates (1, 1), the input portion "9" is set as the position coordinates (2, 1), the input portion "4" is set as the position coordinates (0, 2), the input portion "5" is set as the position coordinates (1, 2), the input portion "1" is set as the position coordinates (0, 3), the input portion "2" is set as the position coordinates (1, 3), and the input portion "3" is set as the position coordinates (2, 3).

These position coordinates are stored in the input section coordinate storage section 19 in association with each input section 12. The input unit coordinate storage unit 19 may generally use a RAM area of a microcomputer, or may use an EEPROM (flash memory or the like).

In the processing up to this point, the setting of the position coordinates of the input unit 12 of the panel-type input device 10 is completed, and then the processing of actual destination floor registration of the elevator car is executed.

Step S12

In step S12, the passenger using the elevator gets into the elevator car, and the operation of the panel-type input device 10 is started. In addition, step S12 represents the behavior of the operator, and is therefore represented by a dashed box. In this operation, when an input signal is generated in the plurality of input units 12 by the hand of the operator, the position coordinates of the corresponding input unit 12 are read. When the operation by the operator is started, the process of step S13 is executed.

Step S13

In step S13, input of an input signal at the first point is detected. This detects that the input unit 12 of the panel-type input device 10 has been operated. Fig. 5 shows details of step S13, which will be described later. When the input of the input signal of the first point is detected, the process proceeds to the next step S14.

Step S14

In step S14, it is determined whether or not an input signal is input from another input unit 12 for a predetermined determined time (here, a predetermined time). If the period input is not increased within the predetermined time, the process proceeds to step S15. On the other hand, in the case where the input is increased, the process of step S14 is executed again. In step S14, the input point detection process shown in fig. 5 is also executed when another input signal is present. Then, when the input of the input signal is finally completed, the process of step S15 is executed.

Step S15

In step S15, a selection process of an input point is performed. In this case, when the input signal is 1, the input signal is specified, but when a plurality of input signals are input, the input unit of the most likelihood is selected and specified as described above.

Next, the control processing in step S13 and step S15 will be described, and first, the processing flow in step S13 will be described with reference to fig. 5.

Step S20

In step S20, it is detected that the hand of the operator approaches the detection area 13 (see fig. 1) of the panel-type input device 10, and an input signal is generated. As described above, when the button is a touch type, the hand of the operator is detected to be in contact with the detection surface of the panel-type input device 10, and an input signal is generated. When the input signal is detected, the process proceeds to step S21.

Step S21

In step S21, it is determined whether or not the hand of the operator is approaching for a predetermined time or longer. In this case, the elapsed time from the generation of the input signal can be measured and determined by the timer. This is based on the idea that, in a case where the operator intentionally instructs the input unit 12, the input unit 12 is instructed within a predetermined time. In addition, the input signal can be obtained by a low-pass filter in order to prevent oscillation.

When the input signal is interrupted before the constant time in this step S12, the process proceeds to step S22, and when the input signal continues for the constant time or longer, the process proceeds to step S23.

Step S22

Since it is determined in step S21 that the input signal is interrupted before the constant time, the process is terminated by skipping to the end of the error signal in step S22 when no input signal is set as the error signal.

Step S23

Since it is determined in step S21 that the input signal continues for the constant time, it is detected in step S23 that the hand of the operator has left the detection area. In this case, the input signal interruption is detected and disengaged. When the interruption of the input signal is detected, the process proceeds to step S24.

Step S24

In step S24, position coordinates that are the detection position of the input unit 12 immediately before the hand of the operator is separated from the detection area are acquired. This coordinate is the position coordinate set in step S11 shown in fig. 4. When the detection position is acquired, the process proceeds to step S25.

Step S25

In step S25, the detection position acquired in step S24 is output. In this case, since it is used in the processing in step S15 described above, it is temporarily stored in the RAM. Since the above processing is also executed for the input signals of the plurality of input units 12, the position coordinates of the plurality of input units 12 based on the operation of the operator are stored in the RAM. If the processing is completed, the process is terminated by jumping to the end.

Next, the processing flow of step S15 will be described with reference to fig. 6.

Step S30

In step S30, it is determined whether or not there are a plurality of input points (input signals). As described above, when a plurality of input signals are input, the process proceeds to step S31, and when 1 input signal is input, the process proceeds to step S35.

Step S31

In step S31, on the assumption that the panel-type input device 10 is mounted in the state shown in fig. 3 in the preceding steps S10 and S11, the input unit 12 that is regarded as the finger where it is located by the operation of the operator is selected. In this selection, the input unit 12 having the largest Y coordinate of the input unit 12 is provisionally selected.

For example, in fig. 1, when the input signals of the input unit "2", the input unit "6", the input unit "7", and the input unit "8" are detected as a plurality of inputs, the input unit "2", which is the position coordinate (1, 3) having the largest position coordinate in the Y-axis direction, is temporarily selected as the input unit 12 having the highest likelihood in step S31. When the temporary selection of the input unit 12 is performed, the process proceeds to step S32.

Step S32

In step S32, based on the information indicating the mounting state of the panel acquired in step S10, it is determined whether or not there is a setting of the wall side direction or the entrance direction. As shown in fig. 3, this determination is made assuming that the operator's hand is extended from the left side of the opening/closing door 31. Therefore, if this setting is not made, the process proceeds to step S35, and the input unit "2" temporarily selected in step S31 is determined. On the other hand, if there is a setting of the wall side direction, it is considered that there is a possibility that the hand of the operator may come from the side of the opening/closing door 31, and the process proceeds to step S33.

In addition, this determination is assumed to be a case where the panel-type input device 10 is mounted on the elevator car of the elevator, and if there is no side wall 30RS, 30LS, this step S32 can be omitted.

Step S33

In step S33, it is determined whether or not an input signal from another input unit 12 is generated in the vicinity of the coordinate of the input unit 12 having the largest Y coordinate. For example, it is determined whether or not there is an input unit 12 in which another input signal is generated in the vicinity of the input unit "2" having the largest Y coordinate temporarily selected in step S31. When there is no other input unit 12 near the input unit "2", the process proceeds to step S35, and the input unit "2" temporarily selected in step S31 is specified.

Here, "vicinity" means "vicinity" when the difference in position coordinates is within a predetermined value range, and in the present embodiment, a case where the input units are adjacent vertically, adjacent horizontally, and adjacent in an oblique direction with respect to a specific input unit 12 is defined as vicinity. For example, the input units "1", "3", "4", "5", and "6" are adjacent ranges to the input unit "2".

On the other hand, if another input unit 12 is present near the input unit "2", it is considered that the hand of the operator may come from the side of the opening/closing door 31, and the process proceeds to step S34. In step S31, since there is the input unit "6" near the input unit "2" having the largest Y coordinate, the process proceeds to step S34.

Step S34

In step S34, the input unit 12 having the largest X coordinate is selected from the input unit 12 having the largest Y coordinate and the input units 12 having generated input signals in the vicinity thereof. Note that the number of the input units 12 in the vicinity is not limited to 1, and a plurality of input units 12 may be provided. Therefore, the input unit 12 having the largest X coordinate is selected from these input units 12.

For example, since the input unit "6" is present near the input unit "2" having the largest Y coordinate temporarily selected in step S31, the input unit 12 having the largest X coordinate is selected by the input unit "2" and the input unit "6" in step S34.

Here, since the position coordinate of the input unit "2" is (1, 3) and the position coordinate of the input unit "6" is (2, 2), the input unit "6" having a large X coordinate is selected. When the selection processing ends, the process proceeds to step S35.

Step S35

In step S35, the input unit 12 selected by the determination in each of steps S30, S32, and S33 is determined as the true input unit 12. The input signal of the determined input unit 12 is registered as a destination floor, and the output is transmitted to the management control device of the elevator. The management control device causes the elevator car to move to the destination floor based on the destination floor sent from the elevator car.

As described above, according to the present embodiment, the plurality of input units to which position coordinates are given are provided on the display panel surface, and when input signals are input from a plurality of input units smaller than the number of the plurality of input units, the relationship between the position coordinates of the plurality of input units that are input is evaluated, and the input unit of the most likely 1 position coordinate is determined as the true input unit.

Thus, it is possible to provide a panel-type input device capable of specifying the most likely input unit even if input signals are unintentionally input from a plurality of input units with a simple system configuration.

Next, another embodiment of the present invention will be described. The above-described embodiment is an embodiment of the panel-type input device 10 attached to an elevator car of an elevator, and the present embodiment is an embodiment of a panel-type input device used in a destination floor registration device installed at an entrance of a waiting hall of a building, for example.

The destination floor registration device is a device that assigns passengers to any of elevator cars of a plurality of elevators, and for example, when a passenger designates a destination floor, the device assigns passengers according to the destination floor, and collectively transfers the passengers to the same destination floor.

As shown in fig. 7, the panel-type input device 41 of this destination floor registration device 40 is mounted on the outer upper surface of the destination floor registration device 40 in parallel with the ground or at a predetermined inclination angle (angle less than right angle). In this case, as shown in fig. 1, a plurality of input units 43 are arranged on the display panel surface 42, and the position coordinates of each input unit 43 are also the same as those shown in fig. 1.

When the operator views the panel input device 41 in a normal state, the front side is defined as the X-axis, and the direction toward the rear side is defined as the Y-axis. Therefore, in this state, the same positional coordinates as those of the panel-type input device 10 shown in fig. 1 are obtained. Therefore, the input unit 12 is likely to be located on the back side of the finger of the operator according to the operation of the operator, and the greater the Y-axis coordinate is, the more likely it is.

However, since the destination floor registration device 40 of the present embodiment is installed at the entrance of the lobby, there is no side wall 30RS or 30LS such as an elevator car, and "status information" is also set to be free of a side wall. Therefore, in the control process, the control steps of steps S32 to S34 shown in fig. 6 are also omitted. Otherwise, the same control processing as in the above-described embodiment is executed.

Fig. 8 shows a broadcasting function of the panel-type input device 10 for passengers present in the elevator car.

In fig. 8, the panel-type input device 10 is provided on a side wall surface of the elevator car in the vertical direction, a speaker 44 is provided on an upper end surface of the panel-type input device 10, and a 3D camera 45 is provided on a lower end side. The 3D camera 45 takes the lower body side of the passenger 47 as the field of view 46, and photographs the lower side of the detection region 13 of the display panel surface, thereby detecting the distance of the passenger approaching the panel-type input device 10. The 3D camera 45 may use a stereoscopic type or ToF type camera.

When the distance to the passenger 47 detected from the image captured by the 3D camera 45 is shorter than the set distance, it is possible to notify the passenger to be away from the panel-type input device 10 by using the speaker. This can suppress the occurrence of useless input.

As described above, according to the present invention, in a panel-type input device for inputting an input signal from an input unit on a display panel surface by an operation of an operator, the panel-type input device is characterized in that a plurality of input units to which position coordinates are given are provided on the display panel surface, and the panel-type input device is provided with a control means for evaluating a relationship between position coordinates of the plurality of input units inputted when input signals are inputted from a plurality of input units smaller than the number of the plurality of input units, and identifying an input unit of the most likely 1 position coordinate as a true input unit.

Thus, it is possible to provide a panel-type input device capable of specifying the most likely input unit even if input signals are unintentionally input from a plurality of input units with a simple system configuration.

The present invention is not limited to the above-described embodiments, and various modifications are possible. The above-described embodiments are described in detail to explain the present invention easily and understandably, and are not limited to having all the configurations described. In addition, a part of the structure of one embodiment may be replaced with the structure of another embodiment, and the structure of another embodiment may be added to the structure of one embodiment. The structure of each embodiment can be added, deleted, and replaced with another structure.
