Each device is provided with a plurality of functions according to the type of the device. The user executes the function by performing an operation according to each function. When the types of devices are different, even if each device has the same function, the operation for performing the function may be different. Also, if the type of device is the same but the manufacturer is different, the operation to perform the same function may differ depending on the device. Furthermore, the installation location of the switch for operating the device differs depending on the device. Also, the type of switch, the arrangement of the switch, and the pictogram may differ depending on the device.

Here, the "switch" is an input means for operating the device, and when the user operates the switch, the function assigned to the switch is executed. A "pictogram" is a symbol or pictogram indicating a function executed by operating a switch.

Since the installation location of the switch differs depending on the device, the user has to search for the installation location of the switch each time he / she tries to operate the device. Further, since the position and pictogram of the switch are different for each device, the user may not be able to instantly determine which switch should be operated.

Further, even users who use the same device may have different functions to be used for each user. Since the switch settings are made before the installation adjustment, it is inconvenient because it cannot be changed according to the actual operation after the installation adjustment. In addition, the switch settings are not optimized according to the usage of each user.

The processing circuit 62 may be configured by dedicated hardware, or may be configured to realize various functions described later by software processing by a built-in processor. Here, as an example, a case where the processing circuit 62 realizes various functions by software processing by the processor will be described.

Here, the processor is a dedicated or general-purpose CPU (Central Processing Unit), GPU (Graphics Processing Unit), application specific integrated circuit (ASIC), programmable logic device, and field programmable gate array (FPGA:). It means a circuit such as Field Programmable Gate Array). Examples of the programmable logic device include a simple programmable logic device (SPLD: Simple Programmable Logic Device) and a compound programmable logic device (CPLD: Complex Programmable Logic Device). The processing circuit 62 realizes each function by reading the program stored in the storage circuit 63 or the program directly incorporated in the processor of the processing circuit 62 and executing the program.

In the latter case, a plurality of storage circuits corresponding to the plurality of processors may be provided, and the program executed by each processor may be stored in the storage circuit corresponding to the processor. As another example, one storage circuit may collectively store programs corresponding to each function of a plurality of processors.

The processing circuit 62 realizes the device selection function 621, the switch function information selection function 622, the control signal generation function 623, and the switch function information editing function 624. The device selection function 621, the switch function information selection function 622, the control signal generation function 623, and the switch function information editing function 624 are realized by the processor of the processing circuit 62 executing the program stored in the storage circuit 63.

May be good.

The device selection function 621 selects a device to be controlled from all the devices existing within a predetermined range around the remote control device 60. A predetermined range around the devices centered on each of the constituent devices 10, 20, 30, and 40 is preset as the determination spaces SP10, SP20, SP30, and SP40. Here, "in advance" means before the device to be controlled is specified by the remote control device 60, and is set at the time of installation adjustment of each of the constituent devices 10, 20, 30, and 40, and is set by the administrator after installation. May be set as appropriate. Further, the "predetermined range" means that the range is set before the device to be controlled is specified by the remote control device 60, and is set at various timings such as during installation adjustment and after installation. It is a good one, and does not mean that it is set at the time of shipment of each of the constituent devices 10, 20, 30, and 40.

The determination space is a range in which a certain device can be determined as a controlled target device by the remote control device 60. The determination space has a radial spread starting from the center of the device, and has a predetermined distance spread toward the outside of the outer edge of the device. Here, the "predetermined distance" means the maximum distance between the remote control device 60 and the control target device when the remote control device 60 is used. The predetermined distance is preset in the remote control device 60. The term "in advance" here is the same as described above.

When the remote control device 60 exists in the determination space of one device, the device selection function 621 selects the one device as the control target device of the remote control device 60. When the remote control device 60 exists in the determination space of a plurality of devices, here, as an example, the device selection function 621 selects the device closest to the remote control device 60 as the control target device among the plurality of devices. .. For example, when the remote control device 60 exists in the determination space SP40 of the sleeper device 40, the device selection function 621 selects the sleeper device 40 as the control target device.

The determination space may be a predetermined range centered on the remote control device 60. That is, the device selection function 621 may specify a device existing in the determination space of the remote control device 60 as a control target device.

The device selection function 621 identifies the constituent devices 10, 20, 30, and 40 based on the ID signal included in the received signal from the communication control device 50.

The device selection function 621 determines which device the remote control device 60 is located in the determination space of which device based on the calculated distance, and identifies the device to be controlled.

The selection of the device to be controlled by the device selection function 621 is not limited to the method using the indoor positioning method. The remote control device 60 may store the positions of the constituent devices 10, 20, 30, and 40 in advance. The device selection function 621 may specify the position of the remote control device 60 in the examination room based on the positional relationship between the remote control device 60 and the communication control device 50. The device selection function 621 may determine which device the remote control device 60 is in in the determination space based on the position of the remote control device 60 in the examination room, and select the device to be controlled.

Further, the remote control device 60 may be configured to directly receive the ID signal of each device transmitted from each of the constituent devices 10, 20, 30, and 40. That is, the communication control device 50 is not an indispensable configuration. When the remote control device 60 receives ID signals from a plurality of devices, the remote control device 60 may select a control target device based on, for example, the signal strength of the ID signals. The signal strength of the ID signal is proportional to the distance between the device transmitting the ID signal and the remote control device 60. Therefore, the device selection function 621 may calculate the distance from the device transmitting the ID signal from the signal strength of the ID signal, and select the device having the closest calculated distance as the control target device.

The device selection function 621 further identifies the user by user authentication such as user ID and biometric authentication.

The switch function information selection function 622 acquires the switch function information of the controlled target device selected by the device selection function 621 from the storage circuit 63, and displays a pictogram on the display 64 based on the switch function information. When the remote control device 60 includes a touch panel, the switch function information selection function 622 generates an operation screen composed of a software switch corresponding to the function of the control target device and a pictogram indicating the function. The generated operation screen is displayed on a touch panel type display.

Further, when the device selection function 621 specifies a user, the switch function information selection function 622 acquires the switch function information of the specified user from the storage circuit 63. The switch function information selection function 622 displays a pictogram on the display 64 based on the switch function information of the specified user. The switch function information can be freely set according to the user's usability and preference. For example, the user can freely set the order of switches and the type of pictogram indicating each function.

Further, the switch function information includes data related to the layout of the operation screen displayed on the touch panel type display, and the user can set the size, shape, display position, and the like of the software switch.

The control signal generation function 623 generates a control signal of the control target device based on the input signal from the input circuit 65. The operated switch and the operation content performed on the switch are input from the input circuit 65 to the control signal generation function 623 as input signals. The control signal generation function 623 identifies a function to be executed by the operated switch and generates a control signal based on the switch function information.

The control signal includes the function, the operation content for the switch, and the ID signal of the device to be controlled. The control signal is transmitted to the communication control device 50 via the transmission circuit 612, and is transmitted from the communication control device 50 to the control target device.

The switch function information editing function 624 registers and edits the switch function information stored in the storage circuit 63. The user can register and edit the switch function information by setting the remote control device 60 in the switch function information edit mode. For example, the remote control device 60 may be changed from the switch mode to the switch function information editing mode by executing a predetermined operation on the switch provided in the input circuit 65.

Here, the "predetermined operation" is, for example, an operation such as pressing a plurality of preset switches at the same time or pressing a predetermined switch a plurality of times in succession. Further, "in advance" here may be before the start of editing the switch function information and may be at the time of shipment of the remote control device 60, or may be appropriately set by the administrator at the time of installation adjustment or after installation. ..

The switch function information editing function 624 displays the switch function information editing screen on the display 64 in the switch function information editing mode.

(2) Operation FIG. 3 is a flowchart showing an example of the operation of the remote control device 60 according to the first embodiment. Here, as an example, an operator carrying a remote control device 60 enters a laboratory in which each component 10, 20, 30, 40 is installed, and a subject is subjected to each component 10, 20, 30, 40. A case of performing an operation for imaging is described. Operations for imaging a subject include setting imaging conditions such as adjusting the X-ray dose and performing X-ray imaging such as X-ray exposure.

For example, in the case of X-ray imaging in the recumbent position, three devices, a high voltage generator 10, an X-ray tube holding device 20, and a sleeper device 40, can be controlled devices of the remote control device 60. Of these three devices, for example, the control target device is selected in the order in which the operator approaches, and an operation for imaging the subject is performed on the control target device.

Hereinafter, the operation of the remote control device 60 according to the embodiment will be described according to the step numbers in the flowchart of FIG.

In step ST101, the device selection function 621 selects a device to be controlled from the constituent devices 10, 20, 30, and 40. Each of the constituent devices 10, 20, 30, and 40 is distinguished based on the ID signal received from the communication control device 50. The device selection function 621 of the remote control device 60 calculates each distance between the remote control device 60 and each of the constituent devices 10, 20, 30, and 40, and based on the calculated distance, which device the remote control device 60 is. It is determined whether or not it exists in the determination space, and the control target device is selected.

In step ST102, the switch function information selection function 622 acquires the switch function information corresponding to the specified controlled device from the storage circuit 63. The switch function information selection function 622 displays a pictogram on the display 64 based on the acquired switch function information.

When the remote control device 60 is a touch panel type display, the switch function information selection function 622 generates an operation screen including a pictogram and a software switch based on the switch function information and displays it on the touch panel type display.

In step ST103, the input circuit 65 inputs an input signal according to the user's operation to the control signal generation function 623. The control signal generation function 623 generates a control signal corresponding to the user's operation and outputs the control signal to the transmission circuit 612.

In step ST104, the transmission circuit 612 transmits a control signal to the control target device via the communication control device 50. The controlled target device that has received the control signal executes a function corresponding to the control signal.

In the case of X-ray imaging in the recumbent position, each time the operator carrying the remote control device 60 moves into the determination space of any one of the high voltage generator 10, the X-ray tube holding device 20, and the sleeper device 40. , The processes of steps ST101 to ST104 are executed. As a result, these three devices are operated in order, imaging conditions in the recumbent position are set, and X-ray imaging is executed. In the case of X-ray imaging in a standing position, the same applies to the above except that the operator approaches the stand device 30 instead of the sleeper device 40 and operates the stand device.

The above is the explanation of the flowchart. Hereinafter, a display example of the switch and pictogram of the remote control device 60 will be described with reference to FIGS. 4 to 8.

FIG. 4 is a schematic diagram illustrating switch function information. FIG. 4 illustrates switch function information when the controlled target device is the sleeper device 40.

As shown in FIG. 4, the switch function information exists for each controlled device. In the first row of the table showing the switch function information of the bed device 40 of FIG. 4, three information items of the switch, the function, and the pictogram are shown. As described above, the switch function information of each control target device defines the correspondence between the function of the control target device assigned to each switch of the remote control device 60 and the pictogram indicating the function.

FIG. 4 shows that the five functions of the sleeper device 40, such as raising the sleeper, lowering the sleeper, horizontally moving the top plate, X-ray imaging, and see-through X-ray, are the mechanical switches 65a, 65b, 65c, 65d, 65e of the remote control device 60. The case where each of the five switches is assigned to the above five switches will be described as an example.

In the second stage of the switch function information of FIG. 4, the function and pictogram of the sleeper device 40 assigned to the mechanical switch 65a of the remote control device 60 are shown. The function assigned to the mechanical switch 65a is X-ray imaging, and the pictogram corresponding to the X-ray imaging is pictogram Ga. In the switch function information, the file name, file path, and the like of the pictogram Ga image data are stored as information items indicating the pictogram Ga.

Similarly, the function assigned to the mechanical switch 65b is the sleeper rise, and the pictogram corresponding to the sleeper rise is the pictogram Gb. The function assigned to the mechanical switch 65c is the sleeper lowering, and the pictogram corresponding to the sleeper lowering is the pictogram Gc. The function assigned to the mechanical switch 65d is fluoroscopy, and the pictogram corresponding to fluoroscopy is pictogram Gd. The function assigned to the mechanical switch 65e is the horizontal movement of the top plate, and the pictogram corresponding to the horizontal movement of the top plate is the pictogram Ge.

The remote control device 60 displays a pictogram on the display 64 based on the switch function information of the device selected as the control target device. FIG. 5 is a diagram illustrating a display example when a pictogram is displayed on the display 64 based on the switch function information of the bed device 40 of FIG.

FIG. 5 is a schematic view showing a first display example of the remote control device 60 according to the first embodiment. FIG. 5 shows an example in which the input circuit 65 of the remote control device 60 is composed of a mechanical switch. FIG. 5 shows a case where the device selection function 621 selects the sleeper device 40 as the control target device. The upper part of FIG. 5 shows the display 64, and the lower part of FIG. 5 shows the input circuit 65.

Five pictograms, pictograms Ga to Ge, are displayed on the display 64. From left to right, pictogram Ga shows the function of X-ray imaging, pictogram Gb shows the function of raising the top plate, pictogram Gc shows the function of lowering the top plate, and pictogram Gd shows the function of X-ray fluoroscopy. The pictogram Ge shows the function of horizontal movement of the top plate.

Each pictogram shows the function assigned from the mechanical switch 65a to the mechanical switch 65e. That is, the pictogram Ga indicates that the mechanical switch 65a is assigned the function of X-ray imaging.

X-ray exposure may be controlled by double action to ensure safety. The double action is a control in which X-rays are actually exposed by performing two operations, an operation for permitting X-ray exposure and an operation for performing X-ray exposure.

In the mechanical switch, the control of the double action is realized by, for example, a two-step push switch. As described above, the remote control device 60 may be configured so that the function requiring the control of the double action is assigned to the mechanical switch capable of realizing the control.

The operation of the mechanical switch 65d corresponding to the X-ray fluoroscopy function may also be set to be controlled by a double action.

When the mechanical switch 65b is pressed, the top plate 41 rises. The remote control device 60 may be configured so that the top plate 41 rises while the mechanical switch 65b is continuously pressed, or when the mechanical switch 65b is pressed, the top plate 41 rises and the top plate 41 rises. The remote control device 60 may be configured so that the top plate 41 stops when the mechanical switch 65b is pressed again. The operation of the mechanical switch 65b when lowering the top plate is the same as that of the mechanical switch 65b.

When the mechanical switch 65e is pressed, the top plate 41 is released from being fixed, and the top plate 41 can be moved manually. Further, the mechanical switch 65e may be configured by a directional switch such as a joystick or a cross switch so that the moving direction of the top plate 41 is controlled according to the direction in which the switch is operated. For example, the medical diagnostic imaging system 1 may be configured so that the top plate moves in the positive direction of the x-axis when the joystick is tilted to the right.

When the remote control device 60 moves from the determination space of the sleeper device 40 to the determination space of the stand device 30, the remote control device 60 selects the stand device 30 as the control target device. That is, the remote control device 60 changes the control target device from the sleeper device 40 to the stand device 30. In this case, a pictogram indicating the function of the stand device 30 is displayed on the display 64, and the function of the stand device is assigned to the mechanical switches 65a to 65e.

FIG. 6 is a schematic view showing a second example of the remote control device 60 according to the first embodiment. FIG. 6 also shows an example of a remote control device 60 including a mechanical switch. The difference between FIG. 6 and FIG. 5 is that the remote control device 60 shown in FIG. 6 does not include the display 64. Further, FIG. 6 shows only a part of the remote control device 60.

FIG. 6 shows an example of a remote control device 60 in which labels indicating the functions of each device are printed on a translucent film instead of the display 64, and a light emitting diode (LED) light is provided under each label. Is shown. A character string indicating each function is printed on the label, and the user can identify the function assigned to the mechanical switch by lighting the LED light under the label. A pictogram may be printed on the label.

In FIG. 6, the label on which the LED light is lit is shown by grayscale hatching, and the label on which the LED light is not lit is shown in white. FIG. 6 shows an example in which the LED light at the bottom of the X-ray exposure label is lit. That is, when the mechanical switch 65a is pressed, X-rays are exposed from the X-ray tube 23.

X-ray exposure is a function that requires double-action control. In this case, the remote control device 60 may be configured so that the LED light blinks in the first operation and indicates that the second operation can be accepted.

5 and 6 have described an example in which the remote control device 60 is configured to include a mechanical switch, but the switch in the remote control device 60 is not limited to the mechanical switch. The switch of the remote control device 60 may be a software switch displayed on the touch panel type display. That is, the remote control device 60 may be configured to display an operation screen composed of a software switch and a pictogram on a touch panel type display. Hereinafter, the operation screen displayed on the remote control device 60 will be described with reference to FIGS. 7 and 8.

FIG. 7 is a schematic view showing a third example of the remote control device 60 according to the first embodiment. FIG. 7 illustrates a case where a tablet terminal provided with a touch panel type display is used as a remote control device 60 of the X-ray device 2a. FIG. 7 shows an example of an operation screen of the remote control device 60 displayed on the touch panel type display.

FIG. 7 shows an example in which an operation screen for operating the five devices of the X-ray device 2a is displayed in a tab format. Each tab displays the sleeper device operation screen TB1, the stand device operation screen TB2, the X-ray tube holding device operation screen TB3, the throttle control device operation screen TB4, and the high voltage generator operation screen TB5.

On the bed device operation screen TB1, three pictograms and three software switches related to the operation of the bed are displayed. From the left, the three pictograms involved in the operation of the bed are the pictogram SG3 indicating the ascent of the top plate, the pictogram SG4 indicating the descent of the top plate, and the pictogram SG5 indicating the horizontal movement of the top plate.

A software switch GU3 for executing the raising function of the top plate is displayed at the lower part of the pictogram SG3 indicating the raising of the top plate. On the software switch GU3, the characters "UP" indicating the rise of the top plate are displayed. When the user selects the software switch GU3, the top plate 41 is raised.

A software switch GU4 for executing the lowering function of the top plate is displayed at the lower part of the pictogram SG4 indicating the lowering of the top plate. On the software switch GU4, the characters "DOWN" indicating the lowering of the top plate are displayed. When the user selects the software switch GU4, the top plate 41 is raised.

A software switch GU5 for executing the horizontal movement function of the top plate is displayed at the lower part of the pictogram SG5 indicating the horizontal movement of the top plate. On the software switch GU5, the characters "FLOAT" indicating the horizontal movement of the top plate are displayed. The user can control the moving direction of the top plate 41 according to the selected position of the software switch GU5.

In the case of a touch panel, the remote control device 60 can acquire the coordinates on the screen selected by the user as an input signal. That is, the remote control device 60 can acquire which software switch is selected and which area of the software switch is selected based on the coordinates selected by the user.

For example, when a predetermined area on the upper side of the paper surface of the software switch GU5 is selected, the top plate 41 moves in the positive direction of the z-axis. On the other hand, when a predetermined region on the lower side of the paper surface of the software switch GU5 is selected, the top plate 41 moves in the negative direction of the z-axis. Similarly, when a predetermined area on the right side of the paper surface of the software switch GU5 is selected, the top plate 41 moves in the positive direction of the x-axis. When a predetermined area on the left side of the paper surface of the software switch GU5 is selected, the top plate 41 moves in the negative direction of the x-axis.

Further, the remote control device 60 operates not only the coordinates on the screen selected by the user, but also the movement of the user's finger or hand on the screen and the time when the user touches the selected coordinates with the finger or hand. It may be configured to be acquired as content.

For example, by displaying an illustration or a photograph of the top plate 41 as a software switch and operating the software switch on the screen so that the user actually moves the top plate 41, the operation of horizontally moving the top plate 41 can be performed. You may be able to enter it.

Further, the remote control device 60 may be provided with a camera or the like and may be configured to recognize movements such as gestures and gestures of the user. Further, the remote control device 60 may include an acceleration sensor or the like, and the user may be able to input a predetermined operation by moving the remote control device 60.

In the case of a tab-type software switch as shown in FIG. 7, the remote control device 60 may be configured so that the tabs are automatically switched according to the controlled target device specified by the device selection function 621. For example, when the self-propelled remote control device 60 moves according to the movement of the user, the remote control device 60 is set so that the tab display is switched according to the position of the user or the position of the self-propelled remote control device 60. It may be configured.

Further, the tab display may be fixed so as not to be switched. Further, the remote control device 60 may be configured so that the user can select whether or not to allow the tab switching according to the change of the control target device.

A tab fixing button GU1 and a tab fixing release button GU2 are shown on the upper part of the touch panel type display of FIG. 7.

The tab fixing button GU1 is a button for setting the remote control device 60 to the tab fixing mode in which the tab is not switched from the tab immediately before the tab fixing button GU1 is selected even if the position of the remote control device 60 changes. The tab fixing release button GU2 is a button that releases the tab fixing mode and sets the remote control device 60 in the tab automatic switching mode in which the tab is automatically switched according to the controlled target device specified by the remote control device 60.

Further, when the user manually selects a certain tab, the remote control device 60 may be configured so that the display screen is fixed to the tab selected by the user. That is, the remote control device 60 may be configured so that the tab does not switch even if the user moves into the determination space of the device different from the control target device displayed on the tab.

The distance at which the remote control device 60 can operate the control target device does not depend on the determination space preset in each of the constituent devices 10, 20, 30, and 40. That is, when the tab is in the fixed mode, the remote control device 60 can operate the control target device even from outside the determination space of the control target device.

FIG. 8 is a schematic view showing a fourth example of the remote control device 60 according to the first embodiment. FIG. 8 shows an operation screen for executing an operation of tilting the bed with a double-action software switch in a modality such as a gastric X-ray diagnostic apparatus.

In the sleeper operation in the gastric X-ray diagnostic apparatus, the sleeper is tilted upside down or tilted backward from a horizontal position. Here, raising and lowering means tilting the sleeper in the yz plane in the direction in which the head of the subject placed on the top plate is higher than the feet. On the other hand, the reverse tilt is to tilt the sleeper in the yz plane in the direction in which the head of the subject placed on the top plate is lower than the foot.

When the sleeper is tilted upside down or tilted backward, it is desirable to control it by double action in order to ensure the safety of the subject. In particular, when the sleeper is tilted in the opposite direction, the subject may fall from the head, so control by double action is desirable.

From the left, a pictogram SG6 indicating the inclination of the bed and a pictogram SG7 indicating the reverse inclination of the bed are shown in the upper part of FIG. 8. At the bottom of the pictogram SG6 indicating the inclination of the bed, a software switch GU6 for executing the inclination of the bed is shown. "Turning down" is displayed on the software switch GU6, indicating that the switch corresponds to the raising / lowering operation of the bed.

A software switch GU71 and a software switch GU72 are displayed at the lower part of the pictogram SG7 indicating the reverse inclination of the bed. The software switch GU71 is indicated by "reverse tilting permission" to indicate that the switch is a switch that allows reverse tilting. The software switch GU72 is shown to be "reverse tilt", indicating that it is a switch for performing reverse tilt.

The software switch GU72 is controlled so that it cannot be operated unless the software switch GU71 is selected. For example, the software switch GU 72 may be controlled so that it is not activated unless the software switch GU 71 is selected.

As described above, according to the medical image diagnosis system 1 provided with the remote control device 60 according to the first embodiment, a plurality of types of functions provided by each of the plurality of devices can be realized by one remote control device 60. .. That is, the remote control device 60 can be used as a controller for the device selected as the control target device by changing the arrangement of the switches and the functions assigned to the switches according to the control target device.

Further, even if the devices are different, the remote control device 60 can set the same operation and the same pictogram on the same switch for the function as long as the functions are the same. That is, even if the devices are different, the mode of the switch can be unified for the same function. By unifying the switches, erroneous operations can be reduced.

Further, the remote control device 60 can be commonly used for a plurality of devices in the examination room. Therefore, when there are a plurality of devices in the examination room, each device can be operated by the remote control device 60 without searching for the switch of each device or moving to the place where the switch of each device is located. ..

Further, the remote control device 60 can change the order of switches and the type of pictogram for each user. That is, even if the functions used by each user in the same device are different, it is possible to provide a switch for each user according to the function used by that user.

For example, one user may often use the X-ray exposure function, while another user may often use the X-ray fluoroscopy function. In such a case, the user may be able to register the functions that he / she frequently uses in the remote control device 60 and edit the operation screen into a screen that he / she can easily operate. Such settings are stored in the switch function information.

Further, in the case of the self-propelled remote control device 60, the user can save the trouble of searching for the remote control device 60, and the user does not have to carry the remote control device 60 according to his / her movement. In particular, when the remote control device 60 is used as a foot switch, if the remote control device 60 is a self-propelled type, the user does not have to get his hands dirty for carrying and can use it hygienically.

When the control signal from the remote control device 60 and the control signal from the switch of the control target device are simultaneously input to the control target device, the medical diagnostic imaging system gives priority to the control signal from the switch of the control target device. 1 may be configured. The control signal to be prioritized may be determined by the modality or the processing circuit built in each device constituting the X-ray device 2a, or by the modality or the transmission / reception circuit detachably attached to the X-ray device 2a. You may.

Further, the medical image diagnosis system 1 may be configured to determine the control signal to be prioritized according to the type of the switch. For example, the control signal of the emergency stop switch should be prioritized regardless of whether it is input from the controlled device or the remote control device 60. In this way, the priority may be set in advance according to the type of switch. Here, "in advance" means before the operation of the controlled target device is started by the remote control device 60, such as when the X-ray device 2a is installed and adjusted. Further, the priority setting may be appropriately set by the administrator after installation.

[Second Embodiment]
