(Block diagram of the X-ray imaging unit 300)
FIG. 7 is a functional block diagram showing the configuration of the X-ray imaging unit 300 of the present embodiment. As shown in FIG. 7, the X-ray imaging unit 300 includes an X-ray imaging apparatus 2 and an operating device 200. The holder 100 has a communication unit 101. The communication unit 101 on the X-ray imaging apparatus 2 side may be provided not in the holder 100 but in the X-ray imaging apparatus main body 1.

The operation device 200 includes an operation unit 280, a control unit 230, a battery 243, a temperature sensor 244, a notification unit 245, and at least two touch sensors, a first touch sensor 241 and a second touch sensor 242. Have.

The control unit 230 integrally controls the operation of each unit of the operating device 200. The control unit 230 includes a communication unit 231, a calibration unit 232, a battery control unit 233, a temperature sensor control unit 234, a touch sensor control unit 235, and a counter 236.

The communication unit 231 is a communication unit on the operation apparatus 200 side, and performs the above-described wireless communication with the communication unit 101 on the X-ray imaging apparatus 2 side.

The battery control unit 233 monitors the remaining amount of the battery 243 by monitoring the voltage of the battery 243 (hereinafter, may be referred to as a battery voltage). The battery 243 is a power supply that supplies power to each unit of the operation device 200 such as the control unit 230, the temperature sensor 244, the notification unit 245, the first touch sensor 241, and the second touch sensor 242.

The temperature sensor control unit 234 controls the driving of the temperature sensor 244. The temperature sensor 244 measures the temperature, and outputs the measured temperature sensor value to the temperature sensor control unit 234. The temperature sensor 244 may be provided inside the front case 250 and the rear case 260, or may be attached to any of the front case 250 and the rear case 260.

The touch sensor control unit 235 controls the driving of the first touch sensor 241 and the second touch sensor 242. The touch sensor control unit 235 outputs a drive signal to the first touch sensor 241 and the second touch sensor 242 at predetermined time intervals, and the first touch sensor 241 and the second touch sensor 242 output capacitance values at predetermined time intervals. It outputs to the touch sensor control part 235 as a touch sensor output value. When a part of the operator's body such as a finger touches the first touch sensor 241 and the second touch sensor 242, the capacitance increases (or decreases).

(A) of FIG. 8 is a diagram showing touch sensor output values in a state where the operator is not in contact with the first touch sensor 241 and the second touch sensor 242, and (b) of FIG. It is a figure showing the touch sensor output value of the state which is contacting the touch sensor 241 and the 2nd touch sensor 242. FIG.

As shown to (a) of FIG. 8, the touch sensor control part 235 is the threshold value with which the touch sensor output value Vout from the 1st touch sensor 241 and the 2nd touch sensor 242 under measurement of the presence or absence of a touch was preset. If the value V1 is smaller than Vth, the operator determines that the first touch sensor 241 and the second touch sensor 242 do not touch. As shown in (b) of FIG. 8, the touch sensor control unit 235 determines that the touch sensor output value Vout from the first touch sensor 241 and the second touch sensor 242 during measurement of the presence or absence of the touch is set in advance. If the value Vh is equal to or higher than Vth, it is determined that the operator is in contact with the first touch sensor 241 and the second touch sensor 242. The touch sensor control unit 235 compares the magnitude relationship between the touch sensor output value Vout and the threshold value Vth for each touch sensor to determine whether the finger or the like of the operator is in contact or non-contact.

As described above, the touch sensor control unit 235 determines whether or not the operator is gripping the operating device 200 based on the touch sensor output values output from the plurality of touch sensors, and the gripping state is Grip state information indicating whether or not That is, touch sensor control unit 235 determines whether the operation of pressing at least one of main switch 210 and option switch 220 is a normal operation intended by the operator or an erroneous operation not intended by the operator. It is also a judgment unit to

Specifically, when the operator grips the operation device 200 to operate the operation unit 280, the area where the first touch sensor 241 of the front case 250 is disposed, and the second touch sensor 242 of the rear case 260 The operator's finger or the like comes into contact with the arranged area, and the capacitance of the first touch sensor 241 and the second touch sensor 242 changes. When the capacitances of both the first touch sensor 241 and the second touch sensor 242 change so that the capacitances of both the first touch sensor 241 and the second touch sensor 242 become equal to or more than the threshold value Vth, the touch sensor control unit 235 Detect (perform grasp detection).

When the operation device 200 has three or more touch sensors, such as four or more, when the capacitance of at least two touch sensors changes so as to be equal to or more than the threshold value Vth, the operation device 200 is gripped. It detects that it is in the gripped state (performs grip detection).

In addition, the touch sensor control unit 235 may monitor whether the touch sensor output value from each touch sensor is constant for a predetermined time or more recorded in advance.

As described above, the operation unit 280 includes the main switch 210 having the first switch member 201 and the second switch member 202, and an option switch 220. When the operator operates the main switch 210 and the option switch 220, the operation unit 280 transmits an operation signal corresponding to the operation to the control unit 230. The operation signal is a signal for operating the X-ray imaging apparatus 2.

When the control unit 230 receives an operation signal from the operation unit 280, and the holding state information acquired by the touch sensor control unit 235 indicates a holding state (that is, when holding detection is performed), the communication unit 231 receives the operation signal. Are transmitted to the communication unit 101 on the X-ray imaging apparatus 2 side. Thereby, the X-ray imaging apparatus 2 performs an operation intended by the operator.

On the other hand, even if the control unit 230 receives an operation signal from the operation unit 280, if the holding state information acquired by the touch sensor control unit 235 is not the holding state (ie, the holding detection is not performed), the communication unit 231 The operation signal is not transmitted to the communication unit 101 on the X-ray imaging apparatus 2 side.

For example, when the operator removes the operating device 200 from the holder 100 and puts it in a pocket of clothes and performs other work other than taking an X-ray image, the operating device 200 is erroneously operated in the pocket. Think. In such a case, one electrode of the first touch sensor 241 and the second touch sensor 242 is in contact with the operator through the clothes in the pocket, so the capacitance changes. However, since the other electrode is not in contact with the operator, the touch sensor control unit 235 detects that the operating device 200 is not in the gripping state. Therefore, even if the operation unit 280 is operated in such a state, the operation signal is not transmitted, and the X-ray imaging apparatus body 1 does not emit X-rays.

In addition, as another operation other than the X-ray imaging, it is conceivable that the operation device 200 in a state of being in the pocket may be in contact with the bed or the like while the patient assistance is being performed. Even in such a case, if the conductor does not contact both the area where the first touch sensor 241 is provided and the area where the second touch sensor 242 is provided, the grip detection unit 240 The controller 200 does not detect that the controller 200 is in the gripping state. Therefore, even if one electrode of the first touch sensor 241 and the second touch sensor 242 contacts the operator through clothes and the other electrode contacts a bed or the like that is not a conductor, the grip detection unit 240 operates It does not detect that the device 200 is in the gripping state.

As described above, the controller device 200 according to the present embodiment includes at least two electrodes as sensors for detecting a touch of a human body, and when two of the electrodes detect a touch, it detects a gripping state. Therefore, the operation signal is not transmitted to the X-ray imaging apparatus main body 1 even if the operation unit 280 is operated in a state not intended by the operator, that is, in a state in which the operation device 200 is not gripped. As a result, it is possible to prevent X-rays from being emitted from the X-ray imaging apparatus main body 1 due to an erroneous operation which is an operation not intended by the operator.

The calibration unit 232 illustrated in FIG. 7 calibrates the threshold value Vth for each of a plurality of touch sensors. The touch sensor control unit 235 detects the contact and non-contact of the finger of the operator or the like for each touch sensor based on the threshold value Vth calibrated by the calibration unit 232 for each touch sensor. Since each touch sensor is capacitive type, its sensitivity changes depending on the external environment. For this reason, in order to prevent a malfunction, the calibration unit 232 calibrates the threshold value Vth for each touch sensor. In the present embodiment, the calibration unit 232 calibrates the threshold value Vth for each touch sensor when a predetermined condition set in advance in the operation device 200 is satisfied.

The notification unit 245 may be, for example, at least one of a buzzer and a light emitting element (LED). The control unit 230 outputs a notification instruction to the notification unit 245 when a predetermined time elapses after the control device 200 is removed from the holder 100. The notification unit 245 performs a notification operation by at least one of sound and light according to a notification instruction from the control unit 230. That is, the notification unit 245 sounds a buzzer or causes the light emitting element to emit light. Thereby, the notification unit 245 notifies the operator that the operating device 200 has been removed from the holder 100 for a predetermined time.

In addition, as described later, if the operator touches the touch sensor with a finger or the like during calibration of the touch sensor, accurate calibration can not be performed. Therefore, the notification unit 245 may perform a notification operation when the calibration unit 232 is performing calibration. In this case, when the calibration unit 232 starts the execution of calibration, the calibration unit 232 outputs a notification instruction to the notification unit 245. Then, in response to a notification instruction from the control unit 230, the notification unit 245 performs a notification operation by at least one of sound and light. That is, the notification unit 245 sounds a buzzer or causes the light emitting element to emit light. Thus, the notification unit 245 notifies the operator not to touch the touch sensor with a finger or the like because calibration is being performed.

The counter 236 counts at least one of the count of the number of operations of the operation unit 280 and the elapsed time after the operation unit 280 is operated.

(Predetermined conditions for calibration)
Next, a predetermined condition that triggers the calibration unit 232 to start the execution of calibration will be described. The calibration performed by the calibration unit 232 will be described later. The calibration unit 232 preferably performs calibration when at least one of predetermined conditions shown in the following (1) to (7) is satisfied. That is, it is preferable that the calibration unit 232 start the execution of the calibration when at least one of the processes in the following steps S11 to S17 is Yes.

As a result, calibration can be performed as needed, as compared with the case where calibration is performed periodically, that is, automatically when a determined time and number of days elapse, as in Patent Document 1. Power consumption can be reduced. As a result, unnecessary battery consumption can be prevented. In addition, accurate grip detection can be performed.

<(1) When the temperature change is above a certain level>
FIG. 9 is a diagram showing the flow of processing of the controller device 200 that performs calibration when the temperature change is equal to or more than a certain level. In this example, it is assumed that the range (predetermined range) of the change amount of the allowable temperature sensor value is set in advance in the temperature sensor control unit 234 based on the temperature sensor value at the time of the previous calibration. That is, the upper limit value and the lower limit value of the allowable temperature sensor value are set as predetermined values based on the temperature sensor value at the time of the previous calibration.

In the example shown in FIG. 9, the temperature sensor control unit 234 monitors whether or not the change amount of the temperature sensor value acquired from the temperature sensor 244 is equal to or more than a predetermined range set in advance (step S11).

When the temperature sensor control unit 234 determines that the amount of change in the temperature sensor value acquired from the temperature sensor 244 is equal to or greater than a predetermined range (Yes in step S11), the calibration unit 232 executes calibration. It is determined that the predetermined condition is satisfied, and calibration of the threshold value Vth is performed for each of the plurality of touch sensors (step S20).

The touch sensor output value which the touch sensor control part 235 acquires from each touch sensor may have a temperature characteristic. Therefore, even if the temperature sensor value changes when the temperature changes, the temperature sensor value does not cause a malfunction (error in detection of contact and non-contact of the operator's finger or the like with each touch sensor). The temperature sensor control unit 234 stores a predetermined value of the amount of change from the time of the previous correction.

Then, when the temperature sensor control unit 234 determines that the amount of change from when the temperature sensor value was corrected before is equal to or greater than the predetermined range, the calibration unit 232 determines that the predetermined condition for performing calibration is satisfied, Perform calibration. Thereby, even if there is a temperature change, the calibration unit 232 can calibrate the threshold value Vth of each touch sensor before causing a malfunction. In addition, after calibrating the threshold value, the calibration unit 232 resets (changes) the range of the temperature sensor value that is allowed based on the temperature sensor value at the time of calibration.

<(2) When the change of the battery voltage is a certain value or more>
FIG. 10 is a diagram showing the flow of processing of the controller device 200 performing calibration when the change of the battery voltage is equal to or more than a predetermined value. In this example, a range (a predetermined range, a predetermined condition regarding the battery voltage) of the change amount of the battery voltage in which the variation is permitted is set in advance in the battery control unit 233 based on the battery voltage at the time of the previous calibration. It is assumed that That is, the upper limit value and the lower limit value of the allowable battery voltage are set as predetermined values based on the battery voltage at the time of the previous calibration.

In the example shown in FIG. 10, the battery control unit 233 monitors whether or not the change amount of the battery voltage of the battery 243 is equal to or more than a predetermined range set in advance (step S12).

When the battery control unit 233 determines that the change amount of the battery voltage of the battery 243 is equal to or more than the predetermined range set in advance (Yes in step S12), the calibration unit 232 satisfies the predetermined condition for performing calibration. It is determined that the threshold value Vth is calibrated for each of a plurality of touch sensors (step S20).

The touch sensor output value obtained by the touch sensor control unit 235 from each touch sensor may change when the battery voltage changes. And since the battery 243 supplies electric power to each part, use of the operating device 200 degrades (decreases) the battery voltage. Therefore, the battery control unit 233 stores a predetermined range in which fluctuation of the battery voltage is permitted without causing a malfunction even when the battery voltage is lowered.

When the battery control unit 233 determines that the amount of change from when the battery voltage was calibrated before is equal to or greater than the predetermined range, the calibration unit 232 determines that the predetermined condition for performing the calibration is satisfied and performs calibration. Run. Thus, even if there is a change in battery voltage, the calibration unit 232 can calibrate the threshold value Vth of each touch sensor before causing a malfunction. Further, after calibrating the threshold value, the calibration unit 232 resets (changes) the range of the acceptable battery voltage based on the battery voltage at the time of calibration.

<(3) When the number of operations of the operation unit 280 or the number of notifications of the notification unit 245 is a predetermined number or more>
FIG. 11 is a diagram showing a flow of processing of the operating device 200 that performs calibration when the number of operations of the operating unit 280 is equal to or more than a certain value.

In this example, the counter 236 counts the number of times the operation unit 280 has been operated (operation number). Further, it is assumed that the predetermined number of operations of the operation unit 280 is set in the counter 236 in advance.

In the example illustrated in FIG. 11, the counter 236 determines whether the number of operations of the operation unit 280, that is, the number of times the main switch 210 or the option switch 220 is pressed, is equal to or greater than a predetermined number of operations previously set. Is monitored (step S13).

Then, when the counter 236 determines that the number of operations of the operation unit 280, that is, for example, the number of times the main switch 210 or the option switch 220 is pressed, is equal to or more than a predetermined number of predetermined operations (Yes in step S13). The calibration unit 232 calibrates the threshold value Vth for each touch sensor (step S20).

Alternatively, the number of times of notification in which the predetermined notification operation of the notification unit 245 has been performed may be set in the counter 236 in advance.

In this case, in step S13 of FIG. 11, the counter 236 monitors whether or not the number of times the notification operation of the notification unit 245 has been performed is equal to or more than a predetermined number of notification times set in advance (step S13).

Then, if the counter 236 determines that the number of times the notification unit 245 has performed the notification operation is equal to or more than the predetermined notification number (Yes in step S13), the calibration unit 232 determines that the predetermined condition for performing calibration is satisfied. The determination is performed, and the calibration of the threshold value Vth is performed for each touch sensor (step S20).

When the operation unit 280 is operated, it is detected that the control unit 230 is operated. Therefore, the battery voltage is reduced by the operation of the operation unit 280. Further, the battery voltage is reduced by the notification operation by the notification unit 245. Therefore, the relationship between the number of operations of the operation unit 280 and the degree of decrease of the battery voltage or the relationship between the number of times of notification operation by the notification unit 245 and the degree of decrease of the battery voltage is grasped in advance. Then, even if the battery voltage drops due to the operation of the operation unit 280 or the notification operation of the notification unit 245, the number of times of operation of the operation unit 280 or the number of notification operations of the notification unit 245 does not cause malfunction. It is stored in the counter 236.

Then, when the counter 236 determines that the number of operations of the operation unit 280 is equal to or greater than a predetermined number of operations or the number of notification operations of the notification unit 245 is equal to or greater than a predetermined number of notifications, the calibration unit 232 determines predetermined conditions for executing calibration. Is determined to be satisfied, and calibration is performed.

Thereby, even if there is a drop in battery voltage caused by the operation of the operation unit 280 or the notification operation of the notification unit 245, the calibration unit 232 can calibrate the threshold value Vth of each touch sensor before causing a malfunction.

In addition, even when the controller 200 does not have a battery voltage sensor that detects a battery voltage, that is, even when the battery control unit 233 does not have a function of monitoring a battery voltage, the processing by software is artificially performed. In addition, the battery control unit 233 can also predict the reduction amount of the battery voltage.

<(4) When replacing the battery>
FIG. 12 is a diagram showing the flow of processing of the controller device 200 that performs calibration when the battery effect is applied. It is assumed that in the battery control unit 233, a predetermined range in which fluctuation is permitted is set in advance with reference to the battery voltage when previously calibrated.

In the example shown in FIG. 12, the battery control unit 233 monitors whether the battery 243 has been replaced (step S14). Specifically, the battery control unit 233 monitors whether or not the battery voltage has risen to a predetermined range or more stored in advance.

When the battery control unit 233 determines that the battery 243 has been replaced (Yes in step S14), that is, when the battery control unit 233 determines that the battery voltage has risen above the upper limit value of the predetermined range, the calibration unit 232 determines It is determined that a predetermined condition for performing calibration is satisfied, and calibration of the threshold value Vth is performed for each touch sensor (step S20).

When the battery 243 that has deteriorated and the battery voltage has decreased is replaced with another battery that has not deteriorated, the battery voltage increases. Therefore, the touch sensor output value obtained by the touch sensor control unit 235 from each touch sensor may change due to battery replacement.

Therefore, the battery control unit 233 stores, in particular, the upper limit value of the predetermined range of the battery voltage which does not cause a malfunction even when the battery voltage rises due to the battery replacement. When the battery control unit 233 determines that the change amount of the battery voltage is equal to or more than the upper limit value of the predetermined range, the calibration unit 232 determines that the predetermined condition for performing the calibration is satisfied, and the threshold value Vth for each touch sensor Perform the calibration of.

Thus, even if there is a change in battery voltage, the calibration unit 232 can calibrate the threshold value Vth of each touch sensor before causing a malfunction.

This allows calibration at the required timing and prolongs the battery life.

<(5) When the device power of the X-ray imaging device 2 is turned on>
FIG. 13 is a diagram showing the flow of processing of the controller device 200 that performs calibration when the power of the X-ray imaging device 2 is turned on. In this example, when the X-ray imaging apparatus 2 which has been stopped is activated by turning on the apparatus power supply of the X-ray imaging apparatus 2, a signal notifying that the apparatus power supply of the X-ray imaging apparatus 2 is turned on The communication unit 101 on the X-ray imaging apparatus 2 side is set to transmit to the communication unit 231 on the operation apparatus 200 side (predetermined condition regarding the power supply of the X-ray imaging apparatus 2).

In the example illustrated in FIG. 13, the communication unit 231 of the controller device 200 intermittently transmits power from the communication unit 101 of the X-ray imaging apparatus 2 at predetermined time intervals from the sleep state. It is monitored whether a signal notifying that it has been input is transmitted (step S15).

Then, when the communication unit 231 on the operation apparatus 200 side receives a signal notifying that the apparatus power of the X-ray imaging apparatus 2 is turned on from the communication unit 101 on the X-ray imaging apparatus 2 side, that is, the X-ray imaging apparatus If it is determined that the device power of 2 is turned on (Yes in step S15), the calibration unit 232 determines that the predetermined condition for performing calibration is satisfied, and performs calibration of the threshold value Vth for each touch sensor (step S20). ).

The timing at which the apparatus power supply of the X-ray imaging apparatus 2 is turned on is often a certain amount of time after the apparatus power supply of the X-ray imaging apparatus 2 is turned off on the night of the same day. For this reason, while the power of the X-ray imaging apparatus 2 is turned off, the temperature around the operation device 200 may change significantly, or the battery voltage of the battery 243 may change significantly. Thereby, the touch sensor output value which the touch sensor control part 235 acquires from each touch sensor changes, and there exists a possibility that a malfunction may be caused.

Therefore, according to the above configuration, even if a certain amount of time elapses after the device power supply of the X-ray imaging device 2 is turned off, even if the touch sensor output value obtained by the touch sensor control unit 235 from each touch sensor changes, Before causing a malfunction, the calibration unit 232 can calibrate the threshold value Vth of each touch sensor.

<(6) When there is no operation of the operating device 200 for a fixed time>
FIG. 14 is a diagram showing a process flow of the operating device 200 that performs calibration when there is no operation of the operating device 200 for a certain period of time.

In this example, the counter 236 is an elapsed time from when the operation unit 210 was operated before to the next operation (that is, after one of the main switch 210 and the option switch 220 is pressed and released thereof). Then, it is assumed that the time until one of the main switch 210 and the option switch 220 is pressed and the press is released is measured. In addition, the counter 236 has a predetermined time since the operation unit 210 was previously operated (ie, one of the main switch 210 and the option switch 220 is pressed and then released) and then the main switch 210 and the option are selected. It is assumed that the predetermined time until pressing of one of the switches 220 and unlocking of the pressing is set.

In the example shown in FIG. 14, the counter 236 monitors whether or not the operation unit 280 has been operated for a predetermined time after the operation unit 280 has been operated (step S16). For example, the counter 236 monitors whether or not an elapsed time since one of the main switch 210 and the option switch 220 was pressed and released last time is equal to or longer than a predetermined time stored in advance.

Then, when the counter 236 determines that the operation unit 280 has not been operated for a certain period of time (Yes in step S16), for example, after one of the main switch 210 and the option switch 220 is pressed last time When the counter 236 determines that the elapsed time in the state where the main switch 210 and the option switch 220 are not pressed and not released is equal to or longer than the predetermined time stored in advance, the calibration unit 232 The calibration of the threshold value Vth is executed (step S20).

If the finger or the like touches the touch sensor while the calibration unit 232 is performing calibration, accurate calibration can not be performed (the process of calibration will be described using FIG. 16).

Therefore, when the operation unit 280 is not operated for a predetermined time, the operator may not touch the touch sensor for a predetermined time without grasping the operation device 200 for a predetermined time.

Therefore, accurate calibration can be performed by performing calibration at the timing when the operator does not operate the operation unit 280 for a predetermined time. This allows calibration at the required timing and prolongs the battery life.

In addition, it is possible to prevent an erroneous calibration from being caused by touching the touch sensor or the like during the calibration and causing a malfunction. Furthermore, the number of recalibrations when the operating device 200 does not operate properly can be reduced, and battery life can be extended.

In addition, when the operation unit 280 is not operated for a predetermined time, there is a possibility that the touch sensor control unit 235 does not perform the grip detection for a certain long time. Therefore, as described above, when the operator does not operate the operation unit 280 for a predetermined time, calibration is performed to calibrate the threshold value Vth of each touch sensor by the calibration unit 232 before causing a malfunction. Can.

The case where the operation unit 280 is not operated for a predetermined time is, for example, the case where the operation device 200 is left at a place other than the holder 100 as an example.

The predetermined time stored in counter 236 may be a predetermined time in an elapsed time from the end of operation of operation unit 280 (when one of main switch 210 and option switch 220 is released). It may be an elapsed time of time when the operation unit 280 is not operated (when one of the main switch 210 and the option switch 220 is not pressed) after the operation device 200 is started.

<(7) When the touch sensor output value is constant for a fixed time>
FIG. 15 is a diagram showing a process flow of the operating device 200 that performs calibration when the touch sensor output value is constant for a predetermined time.

In this example, the touch sensor control unit 235 measures the time during which the touch sensor output value of each touch sensor is within a predetermined range. Further, it is assumed that a predetermined time when the touch sensor output value of each touch sensor is within the predetermined range is set in the touch sensor control unit 235.

In the example illustrated in FIG. 15, the touch sensor control unit 235 monitors whether or not the touch sensor output value is within the predetermined range for each of the plurality of touch sensors (step S17). Specifically, the touch sensor control unit 235 monitors, for each touch sensor, whether the time during which the touch sensor output value is within the predetermined range is equal to or longer than the predetermined time stored in advance.

When the touch sensor control unit 235 determines that all of the plurality of touch sensors have a touch sensor output value within a predetermined range for a predetermined time (Yes in step S17), the calibration unit 232 performs a predetermined calibration. It is determined that the condition is satisfied, and calibration of the threshold value Vth is performed for each touch sensor (step S20).

If the finger or the like touches the touch sensor while the calibration unit 232 is performing calibration, accurate calibration can not be performed (the process of calibration will be described later).

Therefore, if all the touch sensor output values of the touch sensor are within a predetermined range for a predetermined time, the operator may not touch the touch sensor for a predetermined time without grasping the operating device 200 for a predetermined time.

In addition, when the operation unit 280 is not operated for a predetermined time, there is a possibility that the touch sensor control unit 235 does not perform the grip detection for a predetermined time. Therefore, as described above, when the operator does not operate the operation unit 280 for a predetermined time, calibration is performed to calibrate the threshold value Vth of each touch sensor by the calibration unit 232 before causing a malfunction. Can.

Although depending on the resolution of the touch sensor, even if the operator holds the operating device 200 in a stationary state, one of the touch sensors detects a slight movement, and the touch sensor output value of the touch sensor changes. Do.

(Calibration by the calibration unit 232)
FIG. 16 is a diagram showing a flow of calibration processing performed by the calibration unit 232. As described above, the calibration unit 232 starts the execution of calibration when the predetermined condition is satisfied.

As illustrated in FIG. 16, for example, when at least one of the above-described steps S11 to S17 is Yes, next, the calibration unit 232 starts execution of calibration and acquires a touch sensor output value for each touch sensor ( Step S21).

When the calibration unit 232 obtains a touch sensor output value for each touch sensor a predetermined number of times (Yes in step S22), a calibration value, that is, a new threshold value is generated for each touch sensor from a plurality of touch sensor output values for the predetermined number of times. Calculate (step S23). For example, the calibration unit 232 obtains a touch sensor output value for each touch sensor 32 times, and calculates an average value of 32 touch sensor output values for each touch sensor. Then, a calibration value, that is, a new threshold value is calculated for each of the plurality of touch sensors from the average value.

Next, the calibration unit 232 stores the calculated calibration value, that is, the new threshold value in the touch sensor control unit 235 (step S24). Thereby, the calibration by the calibration unit 232 is completed.

Note that among the steps executed by the calibration unit 232, the step of acquiring the touch sensor output value for the predetermined number of times (step S21 and step S22 in the above case) may be referred to as a touch sensor output value acquisition step. Further, among the steps executed by the calibration unit 232, the step of calculating the calibration value (in the above case, step S23) may be referred to as a calibration value calculation step. The calibration unit 232 calibrates the threshold value by executing a calibration process including a touch sensor output value acquisition step and a calibration value calculation step.

As described above, the calibration unit 232 may start the execution of calibration when at least one of the steps S11 to S17 described above is Yes. When the controller device 200 does not perform the process of step S11, the temperature sensor control unit 234 and the temperature sensor 244 may be omitted from the configuration of the controller device 200 illustrated in FIG. 7. When the controller device 200 does not perform the process of step S12, the battery control unit 233 may be omitted from the configuration of the controller device 200 illustrated in FIG. 7. When the controller device 200 does not perform the process of step S13, the counter 236 may be omitted from the configuration of the controller device 200 illustrated in FIG. When the controller device 200 does not perform the process of step S14, the battery control unit 233 may be omitted from the configuration of the controller device 200 illustrated in FIG. When the controller device 200 does not perform the process of step S15, the communication unit 231 of the controller device 200 illustrated in FIG. 7 transmits a signal to the effect that the device power of the X-ray imaging device 2 is turned on. The function of monitoring whether or not it is transmitted from the communication unit 101 on the side may be omitted.

As described above, the calibration unit 232 calculates a calibration value of a certain touch sensor using a plurality of touch sensor output values acquired in time series from the touch sensor.

For example, in the case of the first touch sensor 241, the calibration unit 232 obtains 32 touch sensor output values in time series by the predetermined number of times (for example, 32 times) from the first touch sensor 241 in the touch sensor output value acquisition step. get. Next, the calibration unit 232 calculates the average value of the touch sensor output values from the 32 touch sensor output values acquired in the touch sensor output value acquisition step in the calibration value calculation step, and the first touch sensor from the average value. Calculate the calibration value of 241. Thereafter, the calibration unit 232 calibrates the threshold of the first touch sensor 241 using the calibration value (compensates the threshold to the calculated calibration value). The other touch sensors are also calibrated for each touch sensor.

For this reason, if the touch sensor output value is largely different by touching the touch sensor with the finger or the like while the calibration unit 232 is performing calibration, the accurate calibration value can not be calculated.

Therefore, as described below, a process of determining whether to perform calibration using the calibration value calculated by the calibration unit 232 this time or discard the calibration value calculated this time (do not change the threshold value) may be provided. preferable.

(Contact judgment during calibration 1)
FIG. 17 is a diagram showing a flow of processing for determining the presence or absence of a touch on the touch sensor during the touch sensor output value acquisition step of the calibration unit 232. As shown in FIG. 17, in order to calculate an accurate calibration value, the presence or absence of a touch on the touch sensor may be determined during calibration of the touch sensor by the calibration unit 232.

In the example of the process of the calibration unit 232 shown in FIG. 17, steps S22a to S22f are included in place of step S22 shown in FIG. 16, and further, steps S23a and S25 are included.

Here, the calibration unit 232 will be described as performing the process shown in FIG. 17 after at least one of steps S11 to S17 is executed, but when the process of the calibration unit 232 shown in FIG. The processing of steps S11 to S17 may be omitted. The same applies to the processing described with reference to FIGS. 18 to 25 below.

For example, when at least one of the above-described steps S11 to S17 is Yes (or when execution of calibration starts when predetermined timing or the like comes), the calibration unit 232 then performs a touch sensor, for example. The touch sensor output value is acquired each time (step S21).

When the calibration unit 232 acquires a touch sensor output value for each touch sensor (first step: for example 16 times) which is a part of the total number of times (for example, 32 times) (Yes in step S22a), The calibration unit 232 determines whether the difference (the difference between the maximum value and the minimum value) of the touch sensor output values for the first predetermined number of times is within a predetermined range set in advance, and stores the determination result. (Step S22b).

Then, the calibration unit 232 acquires a touch sensor output value for each touch sensor (step S22 c).

When the calibration unit 232 acquires the touch sensor output value for each touch sensor (the second predetermined number of times (for example, 16 times), which is a part of the total predetermined number of times (for example, 32 times) (Yes in step S22d), The calibration unit 232 determines whether the difference (the difference between the maximum value and the minimum value) of the touch sensor output values for the second predetermined number of times is within a predetermined range set in advance, and stores the determination result. (Step S22e).

Next, the calibration unit 232 determines whether or not the touch sensor output value of each touch sensor has been acquired for the total predetermined number of times (for example, 32 times) necessary to calculate the calibration value (step S22 f). If No in step S22f, the process returns to step S22b.

In step S22f, when it is determined that the calibration unit 232 acquires each touch sensor touch sensor output value for a total predetermined number of times (for example, 32 times) necessary to calculate the calibration value (Yes in step S22f), the next step A calibration value is calculated for each touch sensor from the touch sensor output value of each touch sensor for a predetermined total number of times (for example, 32 times) acquired in S21, S22a, S22d, and S22f (step S23).

Next, the calibration unit 232 refers to the determination result determined in steps S22b and S22e during acquisition of touch sensor output values for the total predetermined number of times, and the touch sensor output value difference for each touch sensor ( It is determined whether or not the difference between the maximum value and the minimum value is within a predetermined range (step S23a: touch sensor output value determination step).

In step S23a, when the calibration unit 232 determines that the difference between the touch sensor output values is within the predetermined range (Yes in step S23a), the calibration value calculated in step S23 is stored in the touch sensor control unit 235 ( Step S24). That is, the calibration unit 232 completes the calibration by correcting the threshold value to the newly calculated calibration value. This is because, in the case of Yes in step S23a, it can be determined that there has been no touch of the operator's finger or the like on the touch sensor until the touch sensor output value for a total predetermined number of times (for example, 32 times) has been acquired. is there. Then, using the calibration value calculated in step 23, the touch sensor control unit 235 performs gripping detection.

On the other hand, when the calibration unit 232 determines in step S23a that the fluctuation of the touch sensor output value is out of the predetermined range (No in step S23a), the calibration value calculated in step S23 is discarded and the calibration value is Are not stored in the touch sensor control unit 235 (step S25). That is, the calibration unit 232 stops the calibration without correcting the threshold and maintains the calibration value at the time of the previous calibration. This is because, in the case of No in step S23a, it can be determined that there has been no touch of the operator's finger or the like on the touch sensor until the touch sensor output value for a total predetermined number of times (for example 32 times) has been acquired. It is because it is not possible to calculate the correct calibration value. As a result, the touch sensor control unit 235 performs the grip detection using the previously calculated calibration value already stored in itself, not the calibration value calculated in step S23.

Note that even if step S22c is omitted, the calibration unit 232 may collectively determine in step S23a whether the fluctuation of the touch sensor output value acquired in step S22b one or more times falls within a predetermined range. Good. Also, the calibration values not used in step S25 may be stored without being deleted.

As described above, according to the calibration illustrated in FIG. 17, the calibration unit 232 determines whether the difference between the touch sensor output values acquired in the touch sensor output value acquiring step (steps S21, S22a, S22c, and S22d) is within the predetermined range. For example, the calibration value calculated in the calibration value calculation step (step S23) after this is stored in the touch sensor control unit 235 (Yes in step S23a; S24). That is, the calibration unit 232 completes the calibration by changing the threshold value to the calibration value calculated in the calibration value calculation step.

If the difference between the touch sensor output values acquired in the touch sensor output value acquisition step (steps S21, S22a, S22c, and S22d) is out of the predetermined range, the calibration unit 232 further calculates the calibration value (step The calibration value calculated in S23) is discarded (No. S25 in step S23a). That is, the calibration unit 232 cancels the calibration by maintaining the threshold stored in the touch sensor control unit 235, which is the calibration value at the time of the previous calibration.

As a result, it is possible to prevent erroneous calibration due to contact of a finger or the like with the touch sensor during calibration. As a result, occurrence of malfunction can be prevented.

In addition, the number of recalibrations when the operating device 200 does not operate properly can be reduced, and the battery life can be extended.

Furthermore, even when the operator holds the operation unit 280 in a tight manner, the touch sensor control unit 235 detects a subtle change in the touch sensor output value, thereby accurately determining whether a finger or the like touches the touch sensor or not. A decision can be made.

In addition, in order to obtain the touch sensor output value while actually performing the calibration and determine the presence or absence of the touch of the finger on the touch sensor based on the touch sensor output value, for example, step S16 (FIG. 14) The determination can be made more accurately than in the case where the process of step S17 (FIG. 15) is performed. The calibration values not used in step S25 may be stored without being deleted.

FIG. 18 is a diagram showing a flow of processing for determining the presence or absence of a touch on the touch sensor after the touch sensor output value acquiring step of the calibration unit 232. As shown in FIG. 18, the calibration unit 232 may collectively perform the touch determination on the touch sensor not in the touch sensor output value acquisition step but after the touch sensor output value acquisition step.

When the calibration unit 232 acquires the touch sensor output value for each touch sensor a predetermined number of times (for example, 32 times) (Yes in step S22), next, the calibration unit 232 compares the touch sensor output values for the predetermined number of times ( It is determined for each touch sensor whether the difference between the maximum value and the minimum value is within a predetermined range (step S23a).

In step S23a, if the calibration unit 232 determines that the difference between the touch sensor output values is within the predetermined range for each touch sensor (Yes in step S23a), the touch sensor touch for a predetermined number of times (for example, 32 times) From the sensor output value, a calibration value is calculated for each touch sensor (step S23).

On the other hand, when the calibration unit 232 determines in step S23a that the difference between the touch sensor output values is outside the predetermined range (No in step S23a), calibration of the touch sensor is not performed without calculating the calibration value of the touch sensor. Cancel

Thus, the calibration unit 232 determines whether the difference between the plurality of touch sensor output values acquired in the touch sensor output value acquisition step (steps S21 and S22) is within the predetermined range or outside the predetermined range. The touch sensor output value determination step (step S23a) is performed before the calibration value calculation step (step S23).

In the touch sensor output value determination step (step S23a), the calibration unit 232 determines that the difference between the plurality of touch sensor output values acquired in the touch sensor output value acquisition step (steps S21 and S22) is within a predetermined range. The threshold value is changed to the calibration value calculated in the calibration value calculation step (step S23).

On the other hand, in the touch sensor output value determination step (step S23a), the calibration unit 232 determines that the difference between the plurality of touch sensor output values acquired in the touch sensor output value acquisition step (steps S21 and S22) is outside the predetermined range. If determined, the calibration value calculation step (step S23) is not performed. That is, in this case, the calibration unit 232 cancels the calibration of the touch sensor without calculating the calibration value of the touch sensor.

Also in this case, as in the process shown in FIG. 17, it is possible to prevent erroneous calibration due to contact of a finger or the like with the touch sensor during calibration. As a result, occurrence of malfunction can be prevented.

FIG. 25 is a diagram showing a flow of processing for canceling the calibration when there is a touch on the touch sensor during the touch sensor output value acquisition step of the calibration unit 232. The calibration unit 232 may end the execution of calibration when it is determined that there is a touch on the touch sensor during calibration, as shown in FIG.

When the calibration unit 232 acquires a touch sensor output value for each touch sensor (first step: for example 16 times) which is a part of the total number of times (for example, 32 times) (Yes in step S22a), The calibration unit 232 determines whether the difference between the touch sensor output values for the first predetermined number of times (the difference between the maximum value and the minimum value) is within a predetermined range set in advance (Step S22 ba).

In step S22ba, if the calibration unit 232 determines that the difference (the difference between the maximum value and the minimum value) of the touch sensor output values for the first predetermined number of times is outside the predetermined range set in advance (No in step S22ba) The calibration of the touch sensor is stopped without calculating the calibration value of the touch sensor.

On the other hand, if the calibration unit 232 determines that the difference between the touch sensor output values (the difference between the maximum value and the minimum value) for the first predetermined number of times is within the predetermined range set in advance (Step S22ba) Yes), the processes of step S22c and step S22d are sequentially performed.

In step S22d, if the calibration unit 232 acquires a touch sensor output value for each touch sensor for a second predetermined number of times (for example, 16 times) which is a part of the total predetermined number of times (for example, 32 times) (Yes in step S22d) Next, the calibration unit 232 determines whether or not the difference (the difference between the maximum value and the minimum value) of the touch sensor output values for the second predetermined number of times is within a predetermined range set in advance (step S22ea).

In step S22d, when the calibration unit 232 determines that the difference between the touch sensor output values for the second predetermined number (the difference between the maximum value and the minimum value) is outside the predetermined range set in advance, The calibration of the touch sensor is stopped without calculating the calibration value of the touch sensor.

On the other hand, in step S22d, the calibration unit 232 determines that the difference (the difference between the maximum value and the minimum value) of the touch sensor output values for the second predetermined number of times is within the predetermined range set in advance. Then, the processes of steps S22f, S23, and S24 are sequentially performed.

Thus, even with the process shown in FIG. 25, an erroneous calibration may be made due to a finger etc. touching the touch sensor during calibration as in the processes shown in FIG. 17 and FIG. Can be prevented. As a result, occurrence of malfunction can be prevented.

(Contact judgment during calibration 2)
The calibration unit 232 may also determine the suitability of the calculated calibration value as shown in FIG. 19 instead of the processing shown in FIGS. 17 and 18. FIG. 19 is a diagram showing a flow of calibration processing including determination of whether the calibration value calculated by the calibration unit 232 is appropriate.

For example, when at least one of the above-described steps S11 to S17 is Yes (or when execution of calibration starts when predetermined timing or the like comes), the calibration unit 232 then performs a touch sensor, for example. The touch sensor output value is acquired each time (step S21). Then, the calibration unit 232 performs the process of steps S22 and S23 described with reference to FIG.

In step S23, the calibration unit 232 calculates a calibration value for each touch sensor from a plurality of touch sensor output values for a predetermined number of times.

Next, the calibration unit 232 determines whether the difference between the calibration value calculated in step S23 and the calibration value (the calibration value stored in the touch sensor control unit 235) calculated at the previous time and currently used is within a predetermined range. It is determined whether or not it is (step S23b).

In step S23b, the calibration unit 232 determines that the difference between the calibration value calculated in step S23 and the calibration value (the threshold stored in the touch sensor control unit 235) when previously calibrated is within the predetermined range. (Yes in step S23b), the calibration value calculated in step S23 is assumed to be normal, and the calibration value is stored in the touch sensor control unit 235 (step S24). That is, the calibration unit 232 changes the threshold value to the calibration value calculated in step S23, and completes the calibration.

In step S23b, if the calibration unit 232 determines that the difference between the calibration value calculated in step S23 and the calibration value (the threshold stored in the touch sensor control unit 235) when previously calibrated is outside the predetermined range (No in step S23b), it is presumed that there is a touch of a finger or the like on the touch sensor during calibration, and the calibration value calculated in step S23 is discarded and is not stored in the touch sensor control unit 235 (step S25). Thereby, the calibration unit 232 cancels the calibration of the touch sensor.

As described above, after the calibration unit 232 starts the execution of the calibration process, the difference between the calibration value calculated in the calibration value calculation step (step 23) and the threshold which is the calibration value when previously calibrated is within the predetermined range If it is inside, the threshold value is changed to the calibration value calculated in the calibration value calculation step (step 23) (step S24).

On the other hand, if the difference between the calibration value calculated in the calibration value calculation step (step 23) and the threshold value is out of the predetermined range, the calibration unit 232 can estimate that there is a touch with a touch sensor or the like during calibration. Therefore, the calibration value calculated in the calibration value calculation step (step 23) is discarded, and the threshold is not changed (step S25). That is, the calibration unit 232 cancels the calibration by maintaining the threshold stored in the touch sensor control unit 235, which is the calibration value at the time of the previous calibration.

In addition, the number of recalibrations when the operating device 200 does not operate properly can be reduced, and the battery life can be extended. The calibration values not used in step S25 may be stored without being deleted.

FIG. 20 is a diagram showing a process flow of a modification example of calibration including determination of whether the calibration value calculated by the calibration unit 232 is appropriate. As shown in FIG. 20, the calibration unit 232 may further determine the magnitude relationship between the calculated calibration value and the currently used threshold value, and adopt a method in which the value is considered to be correct.

As shown in FIG. 20, the processing of steps S21 to S23b described using FIG. 19 is performed.

Then, in step S23b, if the calibration value calculated in the calibration value calculation step (step 23) is outside the predetermined range (No in step S23b), the calibration unit 232 further determines whether the calibration value is smaller than the threshold value. It is determined (step S23c).

In step S23c, when the calibration unit 232 determines that the calibration value calculated in step S23 is smaller than the threshold that was previously calibrated and stored in the touch sensor control unit 235 (No in step S23c), the previously calibrated threshold Rather, it is estimated that the calibration value calculated in step S23 is more accurate, and the calibration value calculated in step S23 is stored in the touch sensor control unit 235 (step S24). Thus, the calibration unit 232 completes the execution of the calibration.

On the other hand, if it is determined in step S23c that the calibration unit 232 determines that the calibration value calculated in step S23 is greater than or equal to the threshold value stored in the touch sensor control unit 235 by calibration last time (Yes in step S23c), The calibrated threshold value is estimated to be more accurate than the calibration value calculated in step S23, and the calibration value calculated in step S23 is discarded and not stored in the touch sensor control unit 235 (step S25). Thereby, the calibration unit 232 cancels the calibration.

According to this, more accurate calibration can be performed. As a result, not only the calibration is performed with the finger or the like touching the touch sensor during calibration, but also the calibration is erroneously performed, and the calibration is incorrectly performed due to other factors, and the operation device 200 malfunctions. Can be prevented.

In addition, since the number of recalibrations when the operating device 200 does not operate properly can be reduced, the influence on the battery life can be reduced. The calibration values not used in step S25 may be stored without being deleted.

(Correction of touch sensor output value during calibration)
The calibration unit 232 may correct a plurality of touch sensor output values acquired simultaneously during calibration.

FIG. 21 is a diagram illustrating a flow of the calibration unit 232 correcting at least one value of the plurality of touch sensor output values while calibration is being performed. The calibration unit 232 may perform the calibration process shown in FIG. 21 instead of the calibration process shown in FIG.

As shown in FIG. 21, for example, when at least one of the above-described steps S11 to S17 is Yes (or when execution of calibration is started, for example, when predetermined timing comes, etc.), the calibration unit 232 A touch sensor output value is acquired for each sensor (step S21).

Next, the calibration unit 232 determines whether at least one touch sensor output value among the touch sensor output values from the touch sensors simultaneously acquired in step S21 is equal to or greater than a threshold (step S21 a).

In step S21a, when the calibration unit 232 determines that at least one touch sensor output value is greater than or equal to the threshold (Yes in step S21a), the touch sensor output value of the touch sensor determined to be greater than or equal to the threshold is Based on the value of the touch sensor output value less than the threshold value, the correction value is corrected to a value less than the threshold value (step S21 b). Thereafter, the processes of steps S22 to S24 shown in FIG. 16 are sequentially performed.

FIG. 22 is a diagram illustrating how the calibration unit 232 corrects at least one value of the plurality of touch sensor output values during calibration. In steps S21a and S21b illustrated in FIG. 21, the calibration unit 232 may correct the touch sensor output value as illustrated in FIG. 22, for example. (A) of FIG. 22 shows that the first touch sensor output value V1out of the first touch sensor 241 is smaller than the threshold, and (b) shows that the second touch sensor output value V2out of the second touch sensor 242 is higher than the threshold It is a figure showing a big appearance.

The operating device 200 includes, for example, two touch sensors of a first touch sensor 241 and a second touch sensor 242 shown in FIG. 7.

In step S21 shown in FIG. 21, the touch sensor output value obtained by the calibration unit 232 from the first touch sensor 241 at a certain time during calibration is the first touch sensor output value V1out shown in (a) of FIG. At the same time, it is assumed that the touch sensor output value acquired by the calibration unit 232 from the second touch sensor 242 is the second touch sensor output value V2out illustrated in (b) of FIG.

Then, the calibration unit 232 refers to the threshold value Vth stored in the touch sensor control unit 235 in step S21a shown in FIG. 21 and determines whether the touch sensor output value is equal to or greater than the threshold value Vth for each touch sensor. judge.

Here, as shown in (a) of FIG. 22, the first touch sensor output value V1out is a value Vl that is less than the threshold value Vth, and as shown in (b) of FIG. 22, the second touch sensor output value V2out is a value Vh which is equal to or greater than the threshold value Vth.

As described above, when only the touch sensor output value from one of the two touch sensors is equal to or greater than the threshold, the operator does not grip (hold) the operation unit 280, It is presumed that a finger or the like has accidentally touched one of the two touch sensors.

In this case, instead of starting the calibration from the beginning, in step S21b, the value Vh of the second touch sensor output value V2out is corrected to the value Vl of the first touch sensor output value V1out. Then, as shown in steps S22 to S24, the calibration unit 232 continues the execution of the calibration and ends the calibration. This makes it possible to prevent recalibration due to a finger or the like touching during calibration, and to delay the battery life.

In the case where the operation device 200 includes two or more touch sensors, such as four touch sensors, the touch sensor output value of one touch sensor is equal to or more than the threshold, and the touch sensor output of another touch sensor When the value is less than the threshold value, the touch sensor output value which is equal to or more than the threshold value may be corrected to be an average value of other touch sensor output values which are less than the threshold value.

(Stop executing calibration during calibration)
The calibration unit 232 may stop the calibration according to the values of the plurality of touch sensor output values acquired simultaneously during the calibration.

FIG. 23 is a diagram showing a flow of stopping the calibration according to the values of the plurality of touch sensor output values while the calibration unit 232 is performing calibration. The calibration unit 232 may perform the calibration process shown in FIG. 23 instead of the calibration process shown in FIG.

As shown in FIG. 23, for example, when at least one of the above-described steps S11 to S17 is Yes (or when execution of calibration is started, for example, when a predetermined timing is reached), the calibration unit 232 next The calibration unit 232 acquires a touch sensor output value for each touch sensor (step S21).

Next, the calibration unit 232 determines that at least one touch sensor output value among the touch sensor output values from the touch sensors simultaneously acquired in step S21 is equal to or greater than the threshold stored in the touch sensor control unit 235. It is determined whether or not (step S21a).

In step S21a, when the calibration unit 232 determines that at least one touch sensor output value is equal to or more than the threshold stored in the touch sensor control unit 235 (Yes in step S21a), the touch sensor output value is output a predetermined number of times. Without acquiring, the calibration is canceled (step S26). After that, the calibration unit 232 may cause the notification unit 245 to perform a notification operation in order to notify that the calibration has not ended normally.

In step S21a, when the calibration unit 232 determines that at least one touch sensor output value is less than the threshold stored in the touch sensor control unit 235 (No in step S21a), the process proceeds to step S22 illustrated in FIG. The process proceeds to steps S23 and S24 in order, and the calibration ends normally.

According to the process illustrated in FIG. 21, the calibration unit 232 estimates that a finger or the like has touched any of the plurality of touch sensors when any of the plurality of touch sensor output values becomes equal to or greater than the threshold, and thereafter Acquisition of the touch sensor output value, that is, the execution of the calibration is discontinued. This can delay the battery life.

(Discards some touch sensor output values during calibration)
The calibration unit 232 may discard some touch sensor output values according to the values of the plurality of touch sensor output values acquired simultaneously during the calibration.

FIG. 24 is a diagram illustrating a flow of discarding part of touch sensor output values according to the values of the plurality of touch sensor output values while the calibration unit 232 is performing calibration. The calibration unit 232 may perform the calibration process shown in FIG. 24 instead of the calibration process shown in FIG.

As shown in FIG. 24, when at least one of the above-described steps S11 to S17 is Yes (or when execution of calibration is started, for example, when predetermined timing comes, etc.), the calibration unit 232 next The calibration unit 232 acquires a touch sensor output value for each touch sensor (step S21).

In step S21a, when the calibration unit 232 determines that at least one touch sensor output value is equal to or more than the threshold stored in the touch sensor control unit 235 (Yes in step S21a), the touch sensor output value equal to or more than the threshold Are discarded (step S21 c).

Then, the processing of steps S22, S23, and S24 is performed, and the calibration unit 232 ends the execution of the calibration.

In step S21a, when the calibration unit 232 determines that at least one touch sensor output value is not greater than or equal to the threshold stored in the touch sensor control unit 235 (No in step S21a), the process of steps S22, S23, and S24 is performed. And complete the calibration run.

In the process shown in FIG. 24, when the process of step S23 is performed after Yes of step S21a, the touch sensor output value of the touch sensor whose touch sensor output value is discarded is data for a predetermined number of times (for example, 32 times). Without, the number of touch sensor output values is smaller by the amount discarded. For example, when one touch sensor output value is discarded, the calibration unit 232 determines the calibration value from the touch sensor output value for the touch sensor by subtracting the number of times discarded from the predetermined number of times. Calculate (step S23).

Thereby, it is possible to suppress the occurrence of recalibration and extend the battery life.
