  The switch 90 includes a copper foil 91 patterned on the upper surface of the substrate 70, an alloy 92 made of copper foil and gold patterned on the upper surface of the substrate 70 so as to be surrounded by the copper foil 91, and an upper surface of the copper foil 91. , A silver carbon 94 pattern printed on the upper surface of the protective film 93, a metal spring 95 provided on the upper surface of the silver carbon 94, and a light diffusion material provided around the metal spring 95 The fixed member 96 made of a resin molded product and a moving member 97 made of a resin molded product of a light diffusing material that is provided on the upper side of the metal spring 95 and is movable in the vertical direction with respect to the fixed member 96. .

  The panel 60 is silk-printed with a symbol representing the function that the functional unit exhibits with the light diffusion material ink. When the LED 50 is lit, the light irradiated by the light diffusion material fixing member 96 and the moving member 97 is diffused, and further, the light representing the function is irradiated with the light. Thereby, the position display 100 (symbol) appears on the operation panel 8, and the position display 100 can be visually recognized by the operator.

  When a symbol corresponding to the position display 100 is pressed by the operator, the panel 60 corresponding to the position display 100 bends downward, and the moving member 97 pressed by the panel 60 moves downward. Further, the metal spring 95 is contracted by the moving member 97 moved downward, the silver carbon 94 is bent downward by the elastic force of the metal spring 95, and the silver carbon 94 and the alloy 92 are brought into contact with each other to be conducted.

  In this way, when a pressing operation on the switch is detected by the panel control unit 13, among the plurality of functional units such as the sheet driving unit 11 and the medical instrument driving unit 14, the functional unit corresponding to the pressed switch is selected. Thus, a control signal for exerting the function is output. As a result, the function is exhibited by the functional unit that has received the control signal.

  Further, the panel control unit 13 determines whether or not the function unit can exhibit a function based on the control signal received from each function unit, and the LED 50 provided around the switch corresponding to the function unit capable of performing the function. Only light up. Thereby, only the position display corresponding to the switch that can be pressed to exhibit each function can be represented.

  Here, regardless of whether or not the function can be exhibited by the function unit, if the position display corresponding to each switch always appears on the operation panel 8, the operator can press the switch that cannot perform the function. Furthermore, it is illusion that the function can be exhibited by pressing the switch.

  For example, if the position display corresponding to the lift switch appears on the operation panel 8 even though the raising of the medical chair 1 is the limit, the operator feels as if the medical chair 1 can still be raised. End up. As a result, the operator is prompted to press the lift switch. Or, if the patient's clothes or cords are sandwiched by the inclination of the medical chair 1, and the position display corresponding to the inclination switch appears on the operation panel 8 even though the driving of the medical chair 1 is prohibited. The operator has the illusion that the medical chair 1 can still be tilted, and if it tilts beyond that, it is urged to press the tilt switch in spite of a dangerous situation.

  Further, in the present embodiment, a warning sound is output from the speaker 20 when the raising switch that cannot function is pressed. However, there is a possibility that the operator may not notice the warning sound because the motor sound of the medical instrument 4, the talking voice, the crying voice of the child, etc. may be very noisy in the hospital. Further, when a plurality of warning sounds are output, the operator may not be able to specify which switch cannot function.

  Therefore, the medical medical device 10 according to the present embodiment controls a plurality of LEDs 50 provided around each switch included in the operation panel 8 by the panel control unit 13 so that the function by the function unit is performed by pressing the switch. The visibility of the position display corresponding to the switch is made different between when the function cannot be exhibited and when the function of the function unit can be exhibited by pressing the switch.

  More specifically, the medical medical device 10 functions by pressing the switch by controlling the plurality of LEDs 50 provided around each switch included in the operation panel 8 by the LED control function of the panel control unit 13. When the function of the unit cannot be exhibited, the LED 50 is stopped and the irradiation of light to the symbol representing the function is stopped. As a result, when the function of the function unit cannot be exhibited by the pressing operation of the switch, the visibility of the position display corresponding to the switch is less recognized by the operator than when the function of the function unit can be exhibited by the pressing operation of the switch. Reduce.

  As described above, the switch that cannot perform the function by the pressing operation is erased from the visual sense of the operator or is hardly visible, so that the operator is not prompted to press the switch that cannot perform the function. Note that “the function cannot be performed” means that a control signal that can specify the pressing operation of the switch is not output to the function unit, and a control signal that can specify the pressing operation of the switch is output to the function unit. Based on this, it means that the function unit does not perform its function, or both.

  Hereinafter, the change in the visibility of the position display by the LED 50 provided in the operation panel 8 will be described more specifically.

[Change visibility of position display]
FIG. 5 is a table for explaining the visibility change of the position display corresponding to each switch. For convenience of explanation, FIG. 5 shows a position display mode only between switches related to a change in visibility of position display. Other blank portions can be applied with a position display mode according to whether or not the function at that time can be exhibited. Further, in the following description, “lighting” of a symbol (including a dot symbol) means that the LED 50 provided around the switch is turned on, and “blinking” means that the LED 50 provided around the switch is turned on. Switching between and off is performed at a predetermined interval, and the symbol “turn off” is realized by turning off the LED 50 provided around the switch.

[Chair auto switch]
As shown in FIG. 5, when the medical chair 1 is being moved to the auto position 1 by pressing the auto 1 switch, the symbol 8a corresponding to the auto 1 switch blinks, the symbol 8b corresponding to the auto 2 switch, and the auto R A symbol 8c corresponding to the switch and a symbol 8d corresponding to the auto S switch are lit.

  When the movement of the medical chair 1 to the auto position 1 is completed, since the medical chair 1 cannot be moved any more even if the auto 1 switch is pressed, the symbol 8a is turned off. On the other hand, since the other switches can perform the chair auto function by pressing, other symbols are lit.

  When the medical chair 1 is being moved to the auto position 2 by pressing the auto 2 switch, the symbol 8b corresponding to the auto 2 switch blinks, the symbol 8a corresponding to the auto 1 switch, the symbol 8c corresponding to the auto R switch, The symbol 8d corresponding to the auto S switch lights up.

  When the movement of the medical chair 1 to the auto position 2 is completed, the symbol 8b is turned off because the medical chair 1 cannot be moved any further by pressing the auto 2 switch. On the other hand, since the other switches can perform the chair auto function by pressing, other symbols are lit.

  When the medical chair 1 is moving to the auto position R by pressing the auto R switch, the symbol 8c corresponding to the auto R switch blinks, the symbol 8a corresponding to the auto 1 switch, the symbol 8b corresponding to the auto 2 switch, The symbol 8d corresponding to the auto S switch lights up.

  When the movement of the medical chair 1 to the auto position R is completed, the symbol 8c is turned off because the medical chair 1 cannot be moved any further even if the auto R switch is pressed. On the other hand, since the other switches can perform the chair auto function by pressing, other symbols are lit.

  When the medical chair 1 is moving to the auto position S by pressing the auto S switch, the symbol 8d corresponding to the auto S switch blinks, the symbol 8a corresponding to the auto 1 switch, the symbol 8b corresponding to the auto 2 switch, The symbol 8c corresponding to the auto R switch is lit.

  When the medical chair 1 is moved to the auto position S, the symbol 8d is turned off because the medical chair 1 cannot be moved any further even if the auto S switch is pressed. On the other hand, since the other switches can perform the chair auto function by pressing, other symbols are lit.

  For example, FIG. 6 is a diagram for explaining a mode of position display when a switch for performing the chair auto function is pressed.

  As shown in FIG. 6 (a), in the state before the pressing operation and the medical chair 1 is not located in any auto position, any of the switches that exhibit the chair auto function is Not pressed, the symbols corresponding to all the switches are lit and the position display appears. Thereafter, as shown in FIG. 6B, when the auto 1 switch is pressed, the medical chair 1 starts to move to the auto position 1. As shown in FIG. 6 (c), when the medical chair 1 is moving to the auto position 1, only the symbol 8a blinks.

  As shown in FIG. 6 (d), when the medical chair 1 has been moved to the auto position 1, the irradiation of light from the LED 50 only on the symbol 8a is stopped, so that only the symbol 8a has the color of the panel (that is, the background). The position display disappears from the operator's field of view. In FIG. 6, for the sake of convenience of explanation, the symbol where the irradiation of light from the LED 50 is stopped is indicated by a broken line, but it is actually disappeared (or the same color as the background color). Similarly, in FIGS. 7 and 8 to be described later, a symbol where irradiation of light from the LED 50 is stopped is represented by a broken line.

  As shown in FIG. 6E, after that, when the auto S switch is pressed and the medical chair 1 is moving to the auto position S, only the symbol 8d blinks. As shown in FIG. 6 (f), when the medical chair 1 has been moved to the auto position S, the irradiation of light from the LED 50 only on the symbol 8d is stopped, so that only the symbol 8d is the color of the panel (that is, the background). The position display disappears from the operator's field of view.

  In this way, irradiation of light from the LED 50 is stopped for the symbols corresponding to the functions that have already completed the movement of the medical device 10 among the chair auto functions. As a result, the position display corresponding to the function for which the movement of the medical apparatus 10 has already been completed is less visible than the position display corresponding to the function for which the movement of the medical apparatus 10 has not yet been completed. Impossible or difficult.

  The chair auto function can be exhibited not only by pressing a switch such as an auto 1 switch but also by a foot operation of the foot controller 5. Therefore, even when the movement of the medical device 10 has already been completed by the foot operation of the foot controller 5, the position display corresponding to the function for which the movement of the medical device 10 has already been completed has not yet completed the movement of the medical device 10. Since the visibility is lower than the position display corresponding to the function that is not present, it is impossible or difficult for the operator to visually recognize the position.

  Further, when the pinching detection unit 19 detects the pinching of the code or the like, the driving of the medical chair 1 is prohibited, and therefore, it corresponds to all the switches related to the movement of the medical device 10 until the pinching detection is released. As for the symbol, irradiation of light from the LED 50 is stopped. As a result, the position displays corresponding to all the switches related to the movement of the medical device 10 are less visible than the position displays corresponding to the other switches, so that it is impossible or difficult for the operator to visually recognize the positions.

  Accordingly, it is possible to prevent the operator from erroneously pressing the switch related to the chair auto function even though the chair auto function cannot be exhibited.

  Furthermore, since only the symbol corresponding to the switch that performs the function blinks, the operator can easily identify the type of the chair auto function that is currently performing the function.

[Switch for chair manual function]
As shown in FIG. 5, when the standing up of the medical chair 1 is the limit by the pressing operation of the standing switch, the medical chair 1 cannot be raised any further by pressing the standing switch. 8e turns off. On the other hand, since the medical chair 1 can be tilted by pressing the tilt switch, the symbol 8f corresponding to the tilt switch is lit.

  When the inclination of the medical chair 1 is the limit by pressing the tilt switch, the sign 8f is turned off because the medical chair 1 cannot be tilted any further by pressing the tilt switch. On the other hand, if the standing switch is pressed, the medical chair 1 can be raised, so that the symbol 8e is lit.

  For example, FIG. 7 is a diagram for explaining an aspect of position display when a switch for exerting a chair manual function is pressed.

  As shown in FIG. 7 (a), the chair manual function is exhibited before the pressing operation and in the state where the medical chair 1 is not positioned at any of the standing, tilting, ascending and descending limit positions. Among the switches to be operated, none of the switches are pressed, and the symbols corresponding to all the switches are lit and the position display appears. As shown in FIG. 7B, after that, when the standing switch is pressed, the medical chair 1 starts to stand continuously or stepwise according to the time or the number of times of pressing. As shown in FIG. 7C, when the standing of the medical chair 1 becomes the limit, the irradiation of light from the LED 50 only on the symbol 8e is stopped, so only the symbol 8e is the panel color (that is, the background color). It becomes a similar color, and the position display disappears from the operator's view.

  As shown in FIG. 7D, when the tilt switch is subsequently pressed, the medical chair 1 starts to tilt continuously or stepwise depending on the time or the number of times of pressing. Furthermore, since the medical chair 1 can stand up again by the inclination of the medical chair 1, light is emitted from the LED 50 to the symbol 8 e. Thereby, the position display corresponding to the standing switch can be visually recognized.

  As shown in FIG. 7E, when the inclination of the medical chair 1 reaches a limit this time, the irradiation of light from the LED 50 only on the symbol 8f is stopped, so that only the symbol 8f has the panel color (that is, the background color). ) And the position display disappears from the operator's field of view.

  Returning to FIG. 5, when the raising of the medical chair 1 is at the limit by the pressing operation of the raising switch, the medical chair 1 cannot be raised any further by pushing the raising switch. Turns off. On the other hand, if the down switch is pressed, the medical chair 1 can be lowered, so that the symbol 8h corresponding to the down switch is lit.

  When the lowering of the medical chair 1 is the limit by the pressing operation of the lowering switch, since the medical chair 1 cannot be further lowered even if the lowering switch is pressed, the symbol 8h is turned off. On the other hand, if the raising switch is pressed, the medical chair 1 can be raised, so that the symbol 8g is lit.

  As described above, in the chair manual function, irradiation of light from the LED 50 is stopped for the symbol corresponding to the function that has already completed the movement of the medical device 10 to the limit position in each direction. As a result, the position display corresponding to the function that has already completed the movement of the medical device 10 to the limit position is less visible than the position display corresponding to the function that has not yet completed the movement of the medical device 10 to the limit position. , It is impossible or difficult for the operator to visually recognize.

  The chair manual function can be exhibited not only by pressing a switch such as a standing switch but also by a foot operation of the foot controller 5. Therefore, even when the medical device 10 has already been moved to the limit position in each direction by the foot operation of the foot controller 5, the position display corresponding to the function that has already completed the movement of the medical device 10 to the limit position is Since the visibility is lower than the position display corresponding to the function that has not yet completed the movement of the medical device 10 to the limit position, the visual recognition by the operator is impossible or difficult.

  Further, when the pinching detection unit 19 detects the pinching of the code or the like, the driving of the medical chair 1 is prohibited, and therefore, it corresponds to all the switches related to the movement of the medical device 10 until the pinching detection is released. As for the symbol, irradiation of light from the LED 50 is stopped. As a result, the position displays corresponding to all the switches related to the movement of the medical device 10 are less visible than the position displays corresponding to the other switches, so that it is impossible or difficult for the operator to visually recognize the positions.

  Accordingly, it is possible to prevent the operator from erroneously pressing the switch related to the chair manual function even though the chair manual function cannot be exhibited.

[Chair speed switch]
The chair speed switch is a switch that can exhibit a function of switching the moving speed of the medical chair 1 between a normal speed and a low speed when pressed for a long time. For this reason, the symbol 8i corresponding to the chair speed switch is always lit regardless of whether the movement speed of the medical chair 1 is controlled to the normal speed or the low speed.

  As shown in FIG. 5, when the moving speed of the medical chair 1 is a normal speed, the dot symbol 80i corresponding to the chair speed switch is turned off, and when the moving speed of the medical chair 1 is a low speed, the dot symbol 80i is changed. Light.

  In this way, the chair speed switch that can always be pressed is urged by the operator to press the symbol 8i. Moreover, according to the visual recognition mode of the dot symbol 80i, the operator can easily specify whether the moving speed of the medical chair 1 is set to the normal speed or the low speed.

[Lighting switch]
The illumination switch is a switch that can exhibit the function of switching the illumination device 7 between illumination and extinction each time it is pressed. For this reason, as shown in FIG. 5, the symbol 8j corresponding to the illumination switch is always lit regardless of whether the illumination device 7 is controlled to be illuminated or extinguished.

  In this way, the lighting switch that can always be pressed is urged by the operator to press the symbol 8j always lit.

[Equipment status switch]
As shown in FIG. 5, when HS1 is equipped, the symbol 8k corresponding to the HS1 switch is turned on, and when HS1 is not equipped, the symbol 8k is turned off. When HS1 is in the selected state, the dot symbol 80k is lit, and when HS1 is being driven, the dot symbol 80k blinks.

  When HS2 is equipped, the symbol 8m corresponding to the HS2 switch is turned on, and when HS2 is not equipped, the symbol 8m is turned off. When HS2 is in the selected state, the dot symbol 80m is lit, and when HS2 is being driven, the dot symbol 80m blinks.

  The symbol 8n corresponding to the LS1 switch is turned on when the LS1 is equipped, and the symbol 8n is turned off when the LS1 is not equipped. When LS1 is in the selected state, the dot symbol 80n is lit, and when LS1 is being driven, the dot symbol 80n blinks.

  When the LS2 is equipped, the symbol 8p corresponding to the LS2 switch is turned on, and when the LS2 is not equipped, the symbol 8p is turned off. Further, when LS2 is in the selected state, the dot symbol 80p is lit, and when LS2 is being driven, the dot symbol 80p blinks.

  When the SC is equipped, the symbol 8q corresponding to the SC switch is turned on, and when the SC is not equipped, the symbol 8q is turned off. When the SC is in the selected state, the dot symbol 80q is lit, and when the SC is being driven, the dot symbol 80q flashes.

  Thus, irradiation of light from the LED 50 is stopped for the symbols corresponding to the switches of the medical instrument 4 that are not equipped. As a result, the position display corresponding to the switch of the medical instrument 4 that is not equipped is less visible than the position display corresponding to the switch of the medical instrument 4 that is equipped. It becomes difficult.

  Accordingly, it is possible to prevent the operator from erroneously pressing the switch for selecting the medical instrument 4 even though it is not equipped.

  Furthermore, since only the dot symbol corresponding to the medical instrument 4 in the selected state is lit, and only the dot symbol corresponding to the medical instrument 4 being driven blinks, the operator can select the medical instrument 4 currently in use. The type can be easily identified.

[HP light switch]
The HP light switch is a switch that can exhibit a function of switching on and off by the HP light only when a pressing operation is performed in a state where any of HS1, HS2, LS1, LS2, and SC is selected. For this reason, as shown in FIG. 5, when any one of HS1, HS2, LS1, LS2, and SC is selected, the symbol 8r corresponding to the HP light switch is lit, and any medical instrument 4 is selected. When there is not, the symbol 8r is turned off.

  When the HP light is lit brightly, the dot symbol 81r and the dot symbol 82r corresponding to the HP light switch are lit. When the HP light is lit darkly, only the dot symbol 81r is lit and the HP light is turned on. When the light is turned off, the dot symbol 81r and the dot symbol 82r are turned off.

  Thus, when none of HS1, HS2, LS1, LS2, and SC is selected, irradiation of light from the LED 50 to the symbol 8r corresponding to the HP light switch is stopped. For this reason, the visibility of the position display corresponding to the HP light switch is lower than when any of HS1, HS2, LS1, LS2, and SC is selected, and it is impossible or difficult for the operator to visually recognize the position display. It becomes.

  Thereby, it is possible to prevent the operator from pressing the HP light switch by mistake even though none of HS1, HS2, LS1, LS2, and SC is selected.

  In addition, it is detected that the HP light provided at the distal end of the selected medical instrument 4 has failed, or the selected medical instrument 4 originally does not have an illumination function, so that light is emitted from the HP light. Even when it is impossible, the irradiation of light from the LED 50 is stopped with respect to the symbol 8r corresponding to the HP light switch. For this reason, the visibility of the position display corresponding to the HP light switch is lower than when light can be emitted from the HP light, making it impossible or difficult for the operator to visually recognize the position.

  As a result, it is possible to prevent the operator from pressing the HP light switch by mistake even though the HP light is broken.

  Furthermore, the operator can easily specify the lighting mode of the HP light according to the visual mode of the dot symbol 81r and the dot symbol 82r.

[HP water injection switch]
The HP water injection switch is a switch that can exhibit the function of switching the water injection by the HP water injection section between on and off only when one of HS1, HS2, LS1, LS2, and SC is pressed. is there. Therefore, as shown in FIG. 5, when any one of HS1, HS2, LS1, LS2, and SC is selected, the symbol 8s corresponding to the HP water injection switch is lit, and any medical instrument 4 is selected. When there is not, the symbol 8s is turned off.

  When the HP water injection is on, the dot symbol 80s corresponding to the HP water injection switch is turned on, and when the HP water injection is off, the dot symbol 80s is turned off.

  Thus, when none of HS1, HS2, LS1, LS2, and SC is selected, irradiation of light from the LED 50 is stopped with respect to the symbol 8s corresponding to the HP water injection switch. For this reason, the visibility of the position display corresponding to the HP water injection switch is lower than when any one of HS1, HS2, LS1, LS2, and SC is selected, and it is impossible or difficult for the operator to visually recognize the position. It becomes.

  Accordingly, it is possible to prevent the operator from pressing the HP water injection switch by mistake even though none of HS1, HS2, LS1, LS2, and SC is selected.

  Further, even when it is detected that the HP water injection section provided at the distal end of the selected medical instrument 4 has failed, for example, when the water cannot be emitted from the HP water injection section, the symbol 8s corresponding to the HP water injection switch In contrast, the irradiation of light from the LED 50 is stopped. For this reason, the visibility of the position display corresponding to the HP water injection switch is lower than when water can be emitted from the HP water injection section, making it impossible or difficult for the operator to visually recognize the position.

  Thereby, it is possible to prevent the operator from erroneously pressing the HP water injection switch even though the HP water injection unit is out of order.

  Furthermore, according to the visual recognition mode of the dot symbol 80s, the operator can easily specify the usage state of the HP water injection.

[Range switch]
The range switch is a switch that can exhibit the function of switching the setting range of the rotation speed of the LS and the setting range of the driving force of the SC only when a pressing operation is performed with any of the LS1, LS2, and SC selected. It is. For this reason, as shown in FIG. 5, when any one of LS1, LS2, and SC is selected, the symbol 8t corresponding to the range changeover switch is lit, and when no medical instrument 4 is selected, the symbol 8t goes out.

  Thus, when none of LS1, LS2, and SC is selected, the irradiation of light from the LED 50 is stopped with respect to the symbol 8t corresponding to the range changeover switch. For this reason, the visibility of the position display corresponding to the range changeover switch is lower than when any one of LS1, LS2, and SC is selected, making it impossible or difficult for the operator to visually recognize the position.

  Accordingly, it is possible to prevent the operator from erroneously pressing the range changeover switch even though none of LS1, LS2, and SC is selected.

[Constant speed / variable speed switch]
The constant speed / variable speed changeover switch is a function for switching the rotational speed mode between the constant speed mode and the variable speed mode only when a pressing operation is performed with any of HS1, HS2, LS1, and LS2 selected. It is a switch that can demonstrate. Therefore, as shown in FIG. 5, when one of HS1, HS2, LS1, and LS2 is selected, the symbol 8u, the dot symbol 81u, and the dot symbol 82u corresponding to the constant speed / variable speed change-over switch are lit. When no medical instrument 4 is selected, the symbol 8u, the dot symbol 81u, and the dot symbol 82u are turned off.

  When the constant speed mode is set, only the dot symbol 82u is lit, and when the variable speed mode is set, only the dot symbol 81u is lit.

  Thus, when none of HS1, HS2, LS1, and LS2 is selected, the irradiation of light from the LED 50 is stopped with respect to the symbol 8u corresponding to the constant speed / variable speed switch. For this reason, the visibility of the position display corresponding to the constant speed / variable speed change-over switch is lower than when any of HS1, HS2, LS1, and LS2 is selected, and the operator cannot visually recognize the position display. Or it becomes difficult.

  As a result, it is possible to prevent the operator from erroneously pressing the constant speed / variable speed switching switch even though none of HS1, HS2, LS1, and LS2 is selected.

  Furthermore, the operator can easily specify the setting state of the rotational speed mode according to the visual recognition mode of the dot symbol 81u and the dot symbol 82u.

[Rotation direction switch]
The rotation direction switching switch is a switch that can exhibit a function of switching the rotation direction mode between the normal rotation mode and the reverse rotation mode only when a pressing operation is performed in a state where either LS1 or LS2 is selected. For this reason, as shown in FIG. 5, when either LS1 or LS2 is selected, the symbol 8v, the dot symbol 81v, and the dot symbol 82v corresponding to the rotation direction selector switch are lit, and any of the medical instruments 4 When not selected, the symbol 8v, the dot symbol 81v, and the dot symbol 82v are turned off.

  When the forward rotation mode is set, only the dot symbol 81v is lit, and when the reverse rotation mode is set, only the dot symbol 82v is lit.

  Thus, when neither LS1 nor LS2 is selected, the irradiation of light from the LED 50 is stopped with respect to the symbol 8v corresponding to the rotation direction switch. For this reason, the visibility of the position display corresponding to the rotation direction switching switch is lower than when either LS1 or LS2 is selected, and it becomes impossible or difficult for the operator to visually recognize the position.

  Accordingly, it is possible to prevent the operator from erroneously pressing the rotation direction changeover switch even though neither LS1 nor LS2 is selected.

  Furthermore, according to the visual recognition mode of the dot symbol 81v and the dot symbol 82v, the operator can easily specify the mode setting state in the rotation direction.

  As described above, the position display corresponding to the HP light switch, the HP water injection switch, the range changeover switch, the constant speed / variable speed changeover switch, and the rotation direction changeover switch appears according to the type of the selected medical instrument 4. There are cases where it does not appear. That is, a function that can be exhibited is determined according to the type of the selected medical instrument 4, and only the position display corresponding to the switch that performs the function appears. On the other hand, since the position display corresponding to the switch that performs the function does not appear, the operator is not prompted to press.

  For example, FIG. 8 is a diagram for explaining a mode of position display when the medical instrument 4 is selected.

  As shown in FIG. 8A, when no medical instrument 4 is equipped, any symbol of the switch relating to driving of the medical instrument 4 is turned off. For this reason, all symbols have colors similar to the panel color (that is, the background color), and the position display disappears from the operator's field of view.

  As shown in FIG. 8B, when HS1 and LS1 are equipped, the symbol 8k corresponding to the HS1 switch and the symbol 8n corresponding to the LS1 switch are lit. Since the other switches cannot perform their functions even if they are pressed, the symbols remain off.

  As shown in FIG. 8C, when HS1 is selected, the dot symbol 80k, the symbol 8r corresponding to the HP light switch, the symbol 8s corresponding to the HP water injection switch, and the constant speed / variable speed switching switch The corresponding symbol 8u lights up. Since the other switches cannot perform their functions even if they are pressed, the symbols remain off.

  Thus, the holding of the medical instrument 4 is released by the operator pressing the switch for selecting the medical instrument 4 in the equipped state or by taking out the medical instrument 4 in the equipped state from the instrument holder 30. When the medical instrument 4 is selected, only the symbols corresponding to the switches that can function by pressing operation are turned on, and the position indications corresponding to the other switches are turned off and disappear from the operator's view. Thus, the operator can easily determine a switch that can exert a function by a pressing operation and a switch that cannot perform a function by a pressing operation (that is, a switch that cannot perform a pressing operation) at a glance. Can do.

  In this embodiment, a liquid crystal operation panel having a touch panel is not used. The reason for this is that, in the case of a liquid crystal type operation panel, since a pressing operation is detected by touching a very thin film, a switch that can be physically pressed by an operator, such as the switch 90 of the present embodiment, This is because the operator cannot feel the click feeling when the switch is pressed effectively. Many doctors who perform dental treatments are elderly, and some doctors feel that they do not feel pressing the switch unless they feel the response when pressing the switch. For this reason, in consideration of securing a click feeling, it is more preferable to use an operation panel that uses a switch that physically presses the operator, such as a switch, instead of a liquid crystal operation panel.

  Further, in the case of a liquid crystal type operation panel, a liquid crystal display must be adopted, so that it becomes more expensive than the operation panel 8 in which the panel 60 on which symbols are silk-printed is placed on the arranged switches. End up.

  Furthermore, if a liquid crystal type operation panel is arranged in a limited design space, a display layer must be provided due to the limitation of the display area. For example, an upper layer on which a switch image for selecting the medical instrument 4 such as HS1, HS2, LS1, LS2, and SC is displayed, an HP light switch that can be pressed when HS1 is selected, an HP water injection switch, and The display must be in a hierarchical format, such as a lower layer on which the switch image of the constant speed / variable speed changeover switch is displayed. If it is an operator who is used to such a hierarchical format, there may be no problem, but it is difficult for an operator who is not used to it, such as an elderly doctor who is engaged in the medical field, and it will be avoided.

  In view of the above, in the present embodiment, a physical switch is provided in order to provide an operation panel that ensures an easy-to-understand operation method for the elderly, while ensuring a click feeling when pressing and reducing costs. While adopting the function, the position display is made to appear or disappear on the operation panel 8 depending on whether or not the function can be exhibited.

  As a result, a switch that can function by pressing operation and a switch that cannot function by pressing operation (that is, a switch that cannot perform pressing operation) while adopting a non-liquid crystal type operation panel that is easy to use even for elderly people When the operation panel 8 is viewed at a glance, it can be easily determined.

[Modification]
The present invention is not limited to the above embodiments, and various modifications and applications are possible. Hereinafter, modified examples applicable to the present invention will be described.

  In the present embodiment, the position display corresponding to the switch that does not perform the function even if the pressing operation is performed is erased from the view on the operation panel 8 so that the operator cannot visually recognize the display, or the pressing operation is performed. However, the position display corresponding to the switch that can perform the function is displayed on the operation panel 8. However, the present invention is not limited to this, as long as the visibility of the position display corresponding to a switch that cannot function even if pressed and the position display corresponding to the switch that can function even if pressed is changed. The position display may be expressed in any manner.

  For example, a position display corresponding to a switch that can perform a function even when a pressing operation is performed represents a color, shape, or size symbol that is inconspicuous to the operator on the operation panel 8, while a switch that can perform a function even when a pressing operation is performed. In the position display corresponding to, symbols of colors, shapes, and sizes that are conspicuous to the operator may be displayed on the operation panel 8.

  In the present embodiment, the position display corresponding to the switch that cannot function even if it is pressed is erased from the view on the operation panel 8 so that it is impossible or difficult for the operator to visually recognize. It cannot be distinguished from the case where the LED 50 is extinguished due to a failure. Therefore, in order to determine whether the visibility has been changed by the LED 50 or whether the LED 50 has failed, a failure determination unit that determines whether the LED 50 has failed is provided. A warning sound may be output from the speaker 20 when it is determined that there is. Further, in order for the operator to check whether or not the LED 50 has failed, when the power is turned on, once all the LEDs 50 are lit, position indications corresponding to all the switches once appear on the operation panel 8. May be.

  In the present embodiment, the control device 9 separate from the operation panel 8 is provided with the panel control unit 13 that controls turning on and off of the LED 50. However, the present invention is not limited to this, and the operation panel 8 may include the panel control unit 13.

  In the present embodiment, the medical treatment apparatus includes a plurality of functional units, and the visibility of the position display is changed for the switches corresponding to the plurality of functional units. However, the present invention is not limited to this, and the visibility of the position display may be changed only for the switch corresponding to one functional unit. In order to further simplify the configuration, a symbol (position display) that is not necessarily required, for example, the symbol 83 indicating that the pressing operation has been performed, may not be provided.

  In the present embodiment, when pinching such as a code is detected by the pinching detection unit 19, the visibility of the position display corresponding to all the switches related to the movement of the medical device 10 is improved until the pinching detection is canceled. It was something to change. However, the present invention is not limited to this, and a switch relating to movement in a direction in which a cord or the like is not pinched, that is, movement in a direction in which pinching detection is released can be displayed on the operation panel 8 without changing the visibility of the position display. Good.

  In the present embodiment, the position display is displayed on the operation panel 8 or turned off by the LED 50, but the position display is displayed on the operation panel 8 using an organic EL (Electroluminescence) made of an organic compound. , It may be erased.

  In the present embodiment, the operation panel provided in the medical medical device installed in a hospital or the like has been illustrated, but the portable medical medical device that can be carried is not limited to such a medical medical device provided. The present invention can also be applied to an operation panel provided. That is, the present invention can be applied to an operation panel included in any medical medical device as long as the operation panel includes a switch that is pressed to perform a function of the functional unit.

  It should be understood that the embodiment disclosed this time is illustrative in all respects and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
