[Explanation of operation panel for management operator]
Next, the configuration and operation of the management operator operation panel 26 will be described. FIG. 3 is a view of the operation panel 26 as viewed from the front direction of the endoscope cleaning apparatus 10. Then, as shown in FIG. 3, the XY axes are set in the plane direction of the operation panel 26. As shown in FIG. 3, a confirmation display panel 44 that can confirm the command input content may be provided separately from the operation panel 26.

  The operation panel 26 in the present embodiment is a panel having a display function and an input function.

  The display function has a function of displaying an image using a backlight unit (not shown) as a light source.

  As an input function, the command input content is recognized by a contact type in which the command input content is recognized by bringing a finger 38 or the like into contact with the display unit 26a which is a liquid crystal screen, or the display unit 26a which is a liquid crystal screen is recognized without contact. The non-contact type is adopted.

  A so-called touch panel is used as a contact type in which the content of command input is recognized by bringing a finger 38 or the like into contact with the display unit 26a which is a liquid crystal screen.

  In addition, as the non-contact type in which the command input content is recognized in a non-contact manner on the display unit 26a which is a liquid crystal screen, the following description is adopted. Therefore, the configuration and operation of the non-contact type operation panel 26 will be described below.

  FIG. 4 is a view of the operation panel 26 as seen from the cross-sectional direction (lateral direction). As shown in FIG. 4, the Z axis is set in a direction perpendicular to the plane direction of the operation panel 26. FIG. 5 is a block diagram showing an outline of the configuration of the operation panel 26 when the image pickup device 36 is built in the operation panel 26.

  As shown in FIG. 5, each pixel on the display screen of the operation panel 26 incorporates an image sensor 36 (see FIG. 5) made up of a light receiving element such as a photodiode. Then, a specific object such as a management operator's finger 38 existing in the space on the display unit 26 a of the operation panel 26 is imaged in a non-contact state by the imaging element 36.

  As shown in FIG. 5, the operation panel 26 has a three-dimensional position information generation unit 40 that generates three-dimensional position information (such as XYZ axis coordinate values) from an image captured by the image sensor 36, and the three-dimensional position information. An input signal generation unit 42 that specifies a command input button (for example, commands A to H in FIGS. 3 and 4) selected based on the input operation and generates an input signal corresponding to the content of the input operation is provided. .

  3 and 4, among the commands A to H displayed on the operation panel 26 and corresponding to the contents of the input operation to be selected, the command G is input by the management operator's finger 38 without touching the operation panel 26. Is shown. As shown in FIG. 3, the command G is displayed on the confirmation display panel 44.

  With respect to the non-contact type operation panel 26 having such a configuration, when a finger 38 is held over the operation panel 26 in a non-contact state, the image sensor 36 (see FIG. 5) including a light receiving element such as a photodiode is obtained. A captured image of the finger 38 is obtained from the captured image. Then, in the three-dimensional position information generation unit 40 (see FIG. 5), the position of the finger 38 on the XY plane (X coordinate, Y coordinate), the distance L between the operation panel 26 and the finger 38 ( (Z coordinate) is estimated, and three-dimensional position information of the finger 38 is generated. Then, the input signal generation unit 42 (see FIG. 5) generates an input signal from the three-dimensional position information, the input signal is notified to the central control unit 32, and the command input operation is completed.

  The position of the finger 38 on the XY plane (X coordinate, Y coordinate) is specifically the position on the XY plane of the tip 38a (see FIGS. 3 and 4) of the finger 38. Further, the distance L (Z coordinate) between the operation panel 26 and the finger 38 is specifically the distance between the operation panel 26 and the lowermost portion 38b (see FIG. 4) of the finger 38.

  As an estimation method for the distance L between the operation panel 26 and the finger 38, it is conceivable to estimate the distance L from the sharpness of the edge portion of the finger 38 (the boundary portion between the finger 38 and the background) in the captured image of the finger 38. . That is, as the finger 38 comes closer to the operation panel 24, the sharpness at the edge portion of the finger 38 becomes higher and the image becomes clearer, while the sharpness at the edge portion of the finger 38 becomes lower as the finger 38 moves away from the operation panel 24. Since the image becomes unclear, the distance L can be estimated from the sharpness of the edge portion of the finger 38.

  Therefore, for example, a lookup table that defines the relationship between the sharpness of the edge portion of the finger 38 obtained by calibration and the distance L is registered in advance in the memory 34 of the central control unit 32 (see FIG. 2). Keep it. Then, it is conceivable to estimate the distance L from the sharpness at the edge portion obtained from the captured image of the finger 38 using the lookup table.

  In addition, as an estimation method for the distance L between the operation panel 26 and the finger 38, it is conceivable to estimate the distance L from the brightness of the captured image of the finger 38.

  That is, the brightness of the finger 38 is obtained from the captured image of the finger 38 synchronized with the reflected light by causing the operation panel 26 to emit light in a specific color at a predetermined time interval using the backlight unit as a light source and reflecting the light on the finger 38. Get. Then, as the finger 38 approaches the operation panel 26, the brightness of the finger 38 increases. On the other hand, the lightness of the finger 38 decreases as the finger 38 moves away from the operation panel 26. Can be estimated.

  Or you may obtain the brightness in the picked-up image of the finger | toe 38 which blocks the illumination light of a room using the illumination light of a room. Since the brightness of the captured image of the finger 38 decreases as the finger 38 approaches the operation panel 26, the brightness of the captured image of the finger 38 increases as the finger 38 moves away from the operation panel 26. The distance L can be estimated from the brightness of the image.

  Therefore, for example, a look-up table that defines the relationship between the brightness of the captured image of the finger 38 obtained by calibration and the distance L is registered in the memory 34 of the central control unit 32 in advance. Then, the distance L is estimated from the brightness obtained from the captured image of the finger 38 using the lookup table.

  FIG. 6 is a diagram showing an example in which an infrared sensor is arranged on the operation panel 26 as a modification of the non-contact type operation panel 26. FIG. 7 is a block diagram showing an outline of the configuration of the operation panel 26 when an infrared sensor is arranged on the operation panel 26.

  As shown in FIG. 6, an infrared light emitting unit 46 and an infrared sensor 48 may be disposed on the operation panel 26 in place of the image pickup device 36 formed of a light receiving element such as the photodiode. As shown in FIG. 6A, a plurality of infrared light emitting units 46 and a plurality of infrared sensors 48 respectively corresponding to the X-axis direction and the Y-axis direction are arranged on the XY plane. ), A plurality of infrared sensors 48 respectively corresponding to the plurality of infrared light emitting units 46 are also arranged in the Z-axis direction. If N infrared sensors 48 corresponding to the N infrared light emitting units 46 are arranged in the Z-axis direction, the distance L between the operation panel 26 and the finger 38 can be recognized up to N stages.

  Thus, also in the example in which the infrared light emitting unit 46 and the infrared sensor 48 are arranged, the distance L (Z coordinate) between the operation panel 26 and the finger 38 is estimated by the infrared light emitting unit 46 and the infrared sensor 48 arranged in the Z-axis direction. be able to. Further, the position (X coordinate, Y coordinate) of the finger 38 on the XY plane can be estimated by the infrared light emitting unit 46 and the infrared sensor 48 arranged in the X axis direction and the Y axis direction.

  The infrared sensor 48 itself may be provided with an infrared light emitting function, and the infrared sensor 48 may be provided with an infrared reflecting portion on the opposite side of the space portion above the operation panel 26 with respect to the infrared sensor 48.

  Further, when an object other than the finger 38 is detected by the image sensor 36 or the infrared sensor 48 including a light receiving element such as a photodiode, the command input process on the operation panel 26 may not be performed.

  In this way, the three-dimensional position information (X coordinate, Y coordinate, Z coordinate) of the finger 38 is acquired, and the display content of the operation panel 26 is changed and command input processing is performed using the acquired result.

  Therefore, an example of the operation of the non-contact type operation panel 26 will be described below.

  When the distance L is within an appropriate distance range, the operation panel 26 is set to the normal mode so that command display can be performed as usual and command input processing can be performed. On the other hand, when the distance L is equal to or less than the appropriate distance, the operation panel 26 is set as a warning mode to display a warning so that command input processing cannot be performed.

  A specific example will be described with reference to FIG. FIG. 8 is a diagram showing an example of command input processing in which the distance L between the operation panel 26 and the finger 38 is divided into four stages. It is assumed that the relationship L1 <L2 <L3 is satisfied.

  As shown in FIG. 8, when L3 ≦ L, the command input process from the operation panel 26 can be performed because the distance from the operation panel 26 to the finger 38 is too long to perform an accurate command input process. I can't do it.

  In addition, when L2 ≦ L <L3, the finger 38 is present at a position within the range of the appropriate distance L. Therefore, the operation panel 26 is set to the normal mode to display a command input screen that accepts command input ( (See FIG. 3) to accept command input. When the finger 38 is moved in the plane direction (XY direction) of the operation panel 26 and the finger 38 is stopped for a predetermined time at a position where the command to be selected is held over, the operation panel 26 inputs the command. recognize.

  Further, when L1 ≦ L <L2, the finger 38 is closer than the predetermined distance L2, and the operation panel 26 and the finger 38 are too close to each other. A warning is displayed indicating that there is a possibility of touching the panel 26, and command input is not accepted. An example of warning display on the operation panel 26 is shown in FIG.

  The warning mode is canceled when the finger 38 is moved away, and can be returned to the normal mode when L2 ≦ L <L3.

  Further, when L <L1, the possibility that the finger 38 actually touches the operation panel 26 is increased. Therefore, it is determined that the finger 38 has touched the operation panel 26 as the contact mode for the operation panel 24. Display. An example of contact display on the operation panel 26 is shown in FIG.

  The above is the description of the configuration and operation of the non-contact type operation panel 26.

  Next, the management operator authentication unit 50 will be described.

  The contact-type or non-contact-type operation panel 26 as described above includes a management operator authentication unit 50 (see FIGS. 5 and 7) that authenticates that a command input person is a management operator. Thus, when the command input person approaches the operation panel 26 to a position equal to or less than a predetermined distance in order to input a command, the management operator authentication unit 50 authenticates whether or not the command input person is a management operator.

  If the command input person is not authenticated by the management operator authentication unit 50 as a management operator, there is a possibility that the command input person is a contaminated cleaning operator or a third party who is not the management operator.

  Therefore, in the case of the contact-type operation panel 26, the contact mode is set when the command input person's finger 38 contacts the operation panel 26 at the time of command input. In the case of the non-contact type operation panel 26, a warning mode is set when L1 ≦ L <L2 when a command is input, and a contact mode is set when L <L1.

  On the other hand, if the command operator is authenticated by the management operator authentication unit 50 as a management operator, it is confirmed that the command input user is a management operator that is considered not contaminated.

  Therefore, in the case of the contact-type operation panel 26, even when the management operator's finger 38 touches the operation panel 26 at the time of command input, the contact mode is not set and the normal mode is maintained, and thereafter the normal mode is maintained. The command display is performed so that command input processing can be performed. Further, in the case of the non-contact type operation panel 26, even when L1 ≦ L <L2 or L <L1 at the time of command input, the warning mode or the contact mode is not set, but the normal mode is maintained. After that, display commands as usual so that command input processing can be performed.

  The management operator authentication unit 50 may be provided outside the operation panel 26 and inside the endoscope cleaning apparatus 10 (see FIG. 2).

  As an authentication method of the management operator authentication unit 50, the management operator authentication unit 50 automatically recognizes the RFID tag of the command input person, accesses a cleaning management server (not shown), and obtains operator information corresponding to the RFID of the command input person. A method of confirming and authenticating and a method of authenticating by biometric authentication are conceivable.

[Explanation on prevention of spread of contamination]
As described above, when the contact type operation panel 26 is adopted, the management operator authentication unit 50 does not authenticate the command input person as the management operator, and the operation panel 26 has the finger 38 of the command input person. If it is recognized that the finger 38 has touched, it is determined that the finger 38 has touched the operation panel 26 as a contact mode, and contact display is performed.

  Further, when the non-contact type operation panel 26 is adopted, when the command operator is not authenticated as the management operator by the management operator authentication unit 50 and L <L1 as described above, As the contact mode, it is determined that the finger 38 is in contact with the operation panel 26, and contact display is performed.

  Therefore, after entering the contact mode once in this way, when the management operator inputs a command again, the contaminated area may come into contact with the contaminated area and the contamination may expand due to secondary contamination. Therefore, the method will be described.

  First, when the contact mode is set, an area in the operation panel 26 that is likely to be touched by the finger 38 and its surrounding area are set as a contamination area.

  Specifically, when the contact mode is set, the contamination area setting unit 54 provided in the operation panel 26 (not shown for the contact type operation panel 26, see FIGS. 5 and 7 for the non-contact type operation panel 26). )), From the information of the X coordinate and the Y coordinate of the finger 38, an operation panel indicates a contaminated area including an area (including an area where the finger 38 is actually in contact) with which the finger 38 is likely to be in contact and an area around the area. 26 is set in the display unit 26a.

  Note that the X coordinate and Y coordinate information of the finger 38 is acquired from the touch panel when the contact-type operation panel 26 is employed. Further, when the non-contact type operation panel 26 is employed, the information is acquired from the three-dimensional position information (X, Y, Z coordinates) of the finger 38 from the three-dimensional position information generation unit 40.

  Then, the set contamination area is notified to the central control unit 32, and the display control of the operation panel 26 is performed by the central control unit 32. As a contamination mode display, a command input button is displayed in the display unit 26a of the operation panel 26. It is displayed in a rearranged state avoiding the contaminated area.

  For example, as shown in FIG. 11, when the area where the command input buttons F and G are initially arranged is set as the contaminated area, the command input buttons F and G are rearranged to areas other than the contaminated area. In FIG. 11, the command input buttons G and H are displayed on the next screen due to the influence of the rearrangement of the command input button F at the position of the initial command input button H. The next screen is displayed by inputting from the next screen input button on the upper left of the operation panel 26.

  Further, display control of the operation panel 26 is performed by the central control unit 32, and in the contaminated region in the display unit 26a of the operation panel 26, as a contamination mode display, a frame indicating the contaminated region and “ The characters “contaminated area” may be displayed.

  The transition from the contamination mode display to the normal mode display can be canceled only by the management operator inputting the password after disinfection.

  Further, when the non-contact type operation panel 26 is employed, when the management operator inputs a command from the operation panel 26 in the contamination mode display, the contamination area set in the operation panel 26 with respect to the XY plane is set. When the three-dimensional position information generation unit 40 recognizes that the finger 38 of the management operator is located, a display for prompting a contamination warning may be performed on the operation panel 26. This can reliably prevent the management operator's finger 38 from accidentally contacting the contaminated area. Therefore, it can be reliably prevented that the management operator mistakenly touches the finger 38 with the contaminated area to expand the contamination.

  As described above, the display function of the operation panel 26 for the management operator is not authenticated by the management operator authentication unit 50 that the command input person is the management operator, and the finger 38 of the command input person is displayed on the operation panel 26. Is determined to have touched, a contaminated area is set based on the two-dimensional position information of the finger 38, and a contamination mode display is performed in which command input buttons are arranged and displayed in an area other than the contaminated area.

  Therefore, a command input button is arranged so that the cleaning operator other than the management operator or the third party may be contaminated by touching the finger 38 so that the management operator does not touch the finger 38. The management operator's finger 38 can be prevented from coming into contact and being contaminated secondarily, and the spread of contamination can be prevented. The apparatus configuration is simple, and such an effect can be obtained while downsizing the apparatus.

  Further, by displaying the frame indicating the contaminated area and displaying the characters “contaminated area” as the contamination mode display, it is possible to more reliably prevent the spread of the contamination to the management operator.

  Further, by disposing the operation panel 24 for the cleaning operator and the operation panel 26 for the management operator separately, it is possible to more reliably prevent the contamination to the management operator.

  In addition, as an input function of the operation panel 24 for the cleaning operator, a non-contact type capable of inputting a command in a non-contact manner on a display unit which is a liquid crystal screen is adopted as in the operation panel 26 for the management operator. It is desirable.

  Although the input device and the medical device of the present invention have been described in detail above, the present invention is not limited to the above examples, and various improvements and modifications may be made without departing from the gist of the present invention. Of course.
