DETAILED DESCRIPTION OF THE INVENTION
  Embodiments of the present invention will be specifically described below with reference to the drawings.
[0009]
Prior to describing the embodiment of the present invention, an example serving as a reference of the present invention will be described.
(FirstReference example)
  1 to 7 show the first of the present invention.Reference exampleFIG. 1 shows the firstReference example2 shows the configuration of the controller, FIGS. 3 and 4 show the warning screen, FIG. 5 shows the configuration of the suction pump unit, and FIGS. 6 and 7 show the warning screen. Show.
[0010]
  As shown in FIG.Reference exampleThe endoscope apparatus 1 is connected to the endoscope 2, the endoscope 2, a unit main body 3 incorporating various devices or apparatuses used for endoscopic examination, and the unit main body 3. And a monitor 4 for displaying an endoscopic image.
[0011]
  The endoscope 2 includes an elongated insertion portion 5, an operation portion 6 formed at the rear end of the insertion portion 5, and a universal cord 7 extending from the operation portion 6. Is provided with a connector 8.
[0012]
  A light guide (not shown) that transmits illumination light is inserted into the endoscope 2, and the connector 8 is connected to the light source unit 11, so that the illumination light generated by the lamp in the light source unit 11 is transmitted to the end of the light guide ( The light guide transmits this illumination light and emits the illumination light transmitted from an illumination window (not shown) at the distal end portion 9 of the insertion portion 5. An observation window is formed adjacent to the illumination window, an objective lens is attached to the observation window, and a solid-state imaging device is disposed at the image formation position of the objective lens, and the formed optical image is photoelectrically converted. Imaging means are formed.
[0013]
  Then, by connecting the scope cable extended from the connector 8 to the video processor unit 12, the photoelectrically converted imaging signal is input to the video processor unit 12, and signal processing is performed to generate a standard video signal. The image is output to the monitor 4 and an endoscopic image is displayed on the display screen of the monitor 4.
[0014]
  In addition, the endoscope 2 has a suction channel for performing suction, and this suction channel is connected to the suction pump unit 14 and performs a suction operation by operating a suction button (not shown), and sucked body fluid, etc. Is stored in a suction bottle stored in the unit body 3.
[0015]
  In the unit main body 3, a light source unit 11, an electric knife unit 13, a suction pump unit 14, a video processor unit 12, and the like are connected via a control line 16 and a controller 15 as control means.
[0016]
  BookReference exampleThen, operation input to the controller 15 is performed from the touch panel 18. This touch panel 18 has a transparent matrix switch pasted on the surface of a color LCD display (not shown). The touch panel 18 outputs a switch or the like as a graphic, detects that the corresponding switch of the graphic is pressed, and detects a man-machine interface. It constitutes.
[0017]
  The operation content input from the touch panel 18 is analyzed by the controller 15, sent to the control line 16 as an operation command, and a light source as a controlled device (also referred to as an endoscope peripheral device) built in the unit body 3. Control unit 11 to suction pump unit 14 (also referred to as functional units 11 to 14).
[0018]
  The unit body 3 includes a lamp replacement door opening / closing detection unit 19 and a suction bottle door opening / closing detection unit 20. The lamp replacement door opening / closing detection unit 19 detects opening / closing of the lamp replacement door, and transmits an opening / closing signal of the lamp replacement door to the controller 15 via the control line 16. The suction bottle door opening / closing detection unit 20 detects opening / closing of the suction bottle door and transmits an opening / closing signal of the suction bottle door to the controller 15 via the control line 16.
[0019]
  FIG. 2 shows the configuration of the controller 15. It has a general DOS / V personal computer configuration.
  A graphic controller 24 that outputs a warning screen or the like is connected to the RAM 23 and the touch panel 18 with a CPU chip set 22 including a CPU as a center, and a storage unit 21 that stores warning screen data and the like via an ISA bus 25. A LAN board 26 connected to the device, an I / O board 27 that performs switch input of the touch panel 18, and, for example, two channels of RS232C 28a and 28b that perform serial transfer are connected. More specifically, the storage unit 21 is a hard disk. Of course, a ROM or a magneto-optical disk device may be used.
[0020]
  BookReference exampleThen, as described below, when a state that should be warned occurs in the endoscopy, the state that should be warned so that the state that should be warned can be notified to an operator, a staff such as a nurse, or a user. Warning information stored in advance corresponding to the signal detected by the detection means is read from the storage means, a warning screen is displayed on the display means, and a situation that should warn the staff or the user is generated. Notice.
[0021]
  Also bookReference exampleThen, this warning screen includes the content for notifying (or instructing) the solution (resolving method) for the state to be warned, and the staff or the user can refer to this warning screen and take action according to the displayed content. The feature is that the state to be warned can be easily resolved.
[0022]
  In this case, when there are a plurality of procedures for performing the treatment or when it is difficult to understand on one screen, the display content is changed according to the procedure of the treatment, and the staff or the user performs the instructed treatment according to the display content. By doing so, we can deal with it quickly and without error. For this reason, state detection means for detecting a state corresponding to the procedure of the treatment (whether or not the state corresponding to the treatment is set depending on whether or not the instructed treatment is performed) is also provided.
[0023]
  More specifically, as one of the controlled devices, for example, the light source unit 11 detects a lamp burnout detection unit of the main lamp that generates illumination light (for example, the lamp burnout detection unit receives the light of the main lamp). And a comparator for determining whether or not the output of the photodetector is equal to or higher than a predetermined level, and the output of the comparator corresponds to whether or not the lamp has run out. When the lamp is detected to be out of lamp, the light source unit 11 turns on the sub lamp so that observation can be maintained, and sends a “lamp out” message to the controller 15 via the control line 16.
[0024]
  The controller 15 that has received the “lamp out” message reads the first warning screen K1 shown in FIG. 3 from the storage unit 21 in the controller 15 as the first warning information from the storage information corresponding to the lamp burnout. For example, it is displayed on the touch panel 18 as a warning screen display means.
[0025]
  On the first warning screen K1, the occurrence of lamp burnout is displayed as a warning state. In addition, a lamp replacement procedure is instructed to eliminate this lamp burnout. In addition, an instruction is given to perform the lamp replacement after the lamp temperature has dropped.
[0026]
  For this reason, the light source unit 11 is provided with a lamp temperature measuring unit (not shown), and in the event of a warning, the lamp temperature is monitored and sent to the controller 15, so that the actual lamp temperature is output to the first warning screen K1. To call attention. Thereby, the replacement | exchange operation | work of a lamp | ramp can be performed more safely.
[0027]
  In addition, it is difficult to understand how to deal with instructions with only words (words).Reference exampleThen, a schematic diagram is displayed, and by referring to the instructions of this schematic diagram, it is possible to perform the treatment easily and without error. That is, a schematic diagram (schematic diagram) of the unit main body 3 is displayed, and the door is illustrated and instructed to open the lamp replacement door of the portion in which the lamp of the light source unit 11 is housed as a procedure to be performed first.
[0028]
  When the lamp replacement door is opened according to the first warning screen K1 shown in FIG. 3, the lamp replacement door opening / closing detection unit 19 detects that the lamp replacement door has been opened and notifies the controller 15 of the opening. When the controller 15 knows that the lamp replacement door is open, it displays a second warning screen K2 on the touch panel 18 as the next warning information as shown in FIG.
[0029]
  And on this 2nd warning screen K2, the schematic of the light source part 11 of the state by which the lamp door was opened is displayed, and the procedure which should be treated on the schematic is shown typically. Specifically, first, an instruction is given to turn the screw to remove the heat sink. The next step is to pull the heat sink toward you as indicated by the arrow.
[0030]
  Then, the lamp part is replaced from the drawn heat sink. After that, a heat sink with a new lamp attached is attached in the light source section, fixed by turning a screw, and further shown in a manner to close the door (not shown).
[0031]
  When the confirmation switch 29 corresponding to the confirmation and display is pressed after performing the instructed action as described above, the controller 15 ends the second warning screen K2 when detecting that the confirmation switch 29 has been pressed. An operation screen will be displayed.
[0032]
  Next, a specific example for the suction pump unit 14 will be shown.
  FIG. 5 is a block diagram of the suction pump unit 14. The pump 31 sucks gastric fluid or the like from the suction channel of the endoscope 2 into the suction bottle 32 by making the pressure in the suction bottle 32 negative.
[0033]
  The suction bottle 32 rides on the weight detection unit 33. Therefore, when the suction bottle 32 becomes heavy enough to be full of water, the weight detection unit 33 detects it (as a warning state) and notifies the control unit 34. Inform. The control unit 34 notifies the controller 15 that the water is full via the control line 16 of FIG.
[0034]
  When the controller 15 receives the full water detection, the controller 15 reads the warning information when the water is full from the storage unit 21 and displays, for example, a third warning screen K3 shown in FIG.
[0035]
  That is, on the third warning screen K3, a warning message indicating that the suction bottle 32 is full is notified by words, and a coping method is described according to the coping procedure. In this case, a schematic diagram (schematic diagram) of the unit main body 3 is displayed, and the door is illustrated and instructed to open the suction bottle replacement door of the portion in which the suction bottle is stored as the first action to be performed.
[0036]
  When a nurse or the like opens the suction bottle door according to the instruction on this screen, the suction bottle door open / close detection unit 20 detects that the door has been opened and notifies the controller 15 of the opening.
  When notified of the state detection that the suction bottle door has been opened, the controller 15 accesses the storage unit 21 again, and displays the fourth warning screen shown in FIG. 7 as the warning information next to the warning screen of FIG. K4 is read and displayed on the touch panel 18.
[0037]
  In this fourth warning screen K4, it is indicated by words that the tube is pulled out and the inner bag in the suction bottle is discarded, and the content of the treatment is also indicated by a schematic diagram.
[0038]
  When the confirmation switch 29 is pressed according to this instruction and the confirmation switch 29 is pressed, the installation of a new inner bag is illustrated (not shown). The replacement procedure can be performed easily and without error.
[0039]
  Thereafter, when the suction bottle replacement door is closed and the confirmation switch 29 is operated, the controller 15 controls the touch panel 18 to display a normal operation screen.
[0040]
  BookReference exampleHas been specifically described with respect to warnings such as replacement work, but of course, the same may be applied to the display at the time of failure.
  BookReference exampleAccording to the above, it is possible to reliably perform an action when an alarm is generated without error, and to perform it easily and quickly.
  For example, the lamp replacement door opening / closing detection unit 19 of FIG. 1 may be provided in the light source unit 11.
[0041]
(SecondReference example)
  Next, the second of the present inventionReference exampleWill be explained. FIG. 8 shows a second embodiment of the present invention.Reference exampleIt is a block diagram of the principal part in the endoscope apparatus. BookReference exampleThe endoscope device of the firstReference exampleIn addition to the above function, when a plurality of warning states occur, a user with a low priority can recognize a high priority at the same time.
[0042]
  BookReference exampleIn the endoscope apparatus 1 shown in FIG. 1, the unit body 35 shown in FIG. 8 is used instead of the unit body 3, and a video printer 36 is connected to the unit body 35.
[0043]
  In the unit main body 35, a light source unit 11, an electric knife unit 13, a suction pump unit 14, a video processor unit 12, and a full water detection unit 40 are connected to the controller 15 via a control line 16.
[0044]
  An operation input to the controller 15 is performed from the touch panel 18. The touch panel 18 has a transparent matrix switch affixed to the surface of a color LCD (not shown). The touch panel 18 outputs a switch or the like as a graphic, detects that the corresponding switch of the graphic is pressed, and uses a man-machine interface. It constitutes.
[0045]
  The operation content input from the touch panel 18 is analyzed by the controller 15 and sent as an operation command to the control line 16 to control the functional units 11 to 14 and 40.
[0046]
  The electrosurgical unit 13 includes a P-code detection unit 13A that is an electrode on the patient side, an S-code detection unit 13B that collects current on the scope side, and an output abnormality detection unit 13C that detects an output abnormality. The information on the unconnected state, the unconnected state of the S code, and the output abnormality is transmitted to the controller 15 via the control unit 13D.
[0047]
  The video printer 36 connected to the outside of the unit main body 35 has a paper jam detection unit 36A. When a paper jam occurs, the control unit 36B transmits it to the controller 15.
  The configuration of the controller 15 in FIG. 2 is that a storage unit 21 ′ is used instead of the storage unit 21, and this storage unit 21 ′ is used when a plurality of warnings occur in addition to the stored information in the storage unit 21 The information of the warning screen for displaying them simultaneously is stored, and the other configuration is the same as in FIG.
[0048]
  Next, using FIG.Reference exampleThe operation of will be described. Assume that the program of the controller 15 periodically checks whether a warning state or the like from the warning detection means has been detected. FIG. 10 shows a warning display processing routine when it is detected that a state to be warned is detected. Hereinafter, detection or reception of a state to be warned is abbreviated as detection or reception of a warning.
[0049]
  When a warning is received, in a first step S1, a file having a predetermined priority is searched to confirm the priority of the warning. In the next step S2, a warning message is output to the display position of the touch panel 18 determined in advance according to the priority order.
[0050]
  The display method (form) is specifically shown below. In this case, it is assumed that the P code unconnected warning and the S code unconnected warning have the same priority, and the paper jam warning has a lower priority.
[0051]
  FIG. 11 shows a position where a warning message (warning display) is issued according to the priority order. The upper 2/3 of the touch panel display screen 18A is used as an important warning display area 41, and high priority items such as warning display 42 without S code connection and warning display 43 without P code display are displayed in this area 41. ing. On the other hand, the video printer paper jam warning display 44 is displayed in the normal warning display area 45 because the priority is low.
[0052]
  Therefore, the user may perform S code connection, P code connection, and removal of jammed paper according to this display. In this case, for example, when the treatment for the S code not connected is not known, the HELP switch 49 displayed on the touch panel display screen 18A is turned on, and the treatment method for the display screen 18A is the first.Reference exampleIt is displayed with a schematic diagram etc. as However, since there are a plurality of warnings, a procedure or method for solving the selected warning is shown.
[0053]
  Then, for example, if the S code connection is performed for the warning shown in FIG. 11, the S code non-connection warning display 42 disappears from the display state shown in FIG. 11, and the P code non-connection warning display 43 and the video printer paper jam. Only the warning display 44 remains and is displayed.
[0054]
  In this case, the remaining warning display may be displayed in consideration of the warning priority again.
[0055]
  Further, when the P code connection is further performed, the P code non-connection warning display 43 disappears and only the video printer paper jam warning display 44 is displayed.
  Note that the warning shown in FIG. 11, for example, the warning with the highest priority is not required to be resolved first, but the P code connection or video printer paper jam is not the first action to be taken. You may take action against.
[0056]
  When multiple warnings occur in this way, the warnings are displayed at the same time, so that the entire warning situation in the endoscope apparatus at that time can be grasped, and the user can select it in that situation. Actions for warnings can be performed sequentially.
  In FIG. 11, the priority is two levels of high / low, but this area may be set to three or more levels to correspond to three or more levels of priority.
[0057]
  FIG. 12 shows another output (display) method. In this specific example, a message with a higher priority is displayed at the upper left. Accordingly, high priority items such as S code unconnected 46 and P code unconnected 47 are displayed on the upper left corner, and low priority items such as paper jam 48 are displayed on the lower right corner. .
[0058]
  Accordingly, the user can recognize that the warning displayed at the upper left is more important, and can respond according to the degree of importance. In this display example, in order to prevent the display windows from overlapping and the warning display from becoming invisible, a heading portion such as “S code not connected” is described at the bottom of the window.
[0059]
  Moreover, the notation method according to the warning priority is used for the display. In other words, those with a high degree of warning are marked as “warning” and are enclosed in a frame for easy viewing. And those with a low warning level are marked as “Caution”. Moreover, the treatment method with respect to warning is explained in words. And a user should just respond | correspond to these warnings.
[0060]
  In this case, if it is difficult to understand with words alone, the HELP switch 49 is operated to select the order of actions to be taken in response to the warning or the like in this display state. It is possible to select whether or not to display the treatment procedure or treatment method for the user etc., so even a user who is not familiar with the structure of the endoscope apparatus can make an error. In addition, a warning can be taken in a short time. In addition, the first action procedure for warningsReference exampleThe description is omitted here.
[0061]
  BookReference exampleThen, when a plurality of conditions such as warnings occur, the priority and the like are taken into consideration at the same time, so the user can grasp the entire situation at that time.
  In addition, since the priority may be different for each user, the user can select and take action from displayed contents such as a plurality of warnings.
[0062]
  In this display example, when the priority order is the same order, it is displayed in a predetermined order from the original position toward a place with a low priority level. The display position may be determined in accordance with this idea.
[0063]
  Furthermore, although the notation is changed according to the degree of warning, the color, shape, and font may be changed, or the display method such as blinking may be changed.
  Thus, the user can surely know the warning and can also recognize the importance of the warning at the same time, and can take a more appropriate action.
  Other effects are the firstReference exampleHas the same effect.
[0064]
(ThirdReference example)
  Then the thirdReference exampleWill be explained. thisReference exampleThe configuration of the secondReference exampleAnd the display form of the warning screen is different. FIG. 13 shows the thirdReference exampleA specific example of the warning screen is shown. SecondReference exampleSimilarly to the third operation screen, a representative operation screen displayed on the touch panel 18 in the endoscope apparatus in which a plurality of controlled devices are centrally controlled by a single touch panel 18 is displayed on the third operation screen.Reference exampleThe example which displayed the warning according to is shown.
[0065]
  BookReference exampleThe screen includes an operation screen 151, an important error window 152, a general error window 153, and a confirmation switch 154. The important error window 152 is a window frame 160 having a thick frame so as to stand out from the frame of the general window 153.
[0066]
  The action is that when an event that should alert the user occurs in the endoscope apparatus, depending on the degree of the predetermined event, when the event is an important error, the important window 152 A message is displayed in the thick window frame 160 (however, a warning message is omitted in FIG. 13).
[0067]
  On the other hand, when an event occurring in the endoscope apparatus is a normal error, a message is displayed in the frame of the general window 153. When the user has confirmed the message, each window can be closed by pressing the confirmation switch 154 to return to the normal operation screen.
[0068]
  Therefore, even when an important error and a normal error occur at the same time, the user can confirm both errors and settle down.
  Also bookReference exampleIn this case, the window frame 155 of the important window 152 is made conspicuous by making it thick, but it may be displayed in red or by changing the shape of the frame.
[0069]
(ThirdReference exampleVariation of
  FIG. 14 shows the thirdReference exampleThe warning screen regarding the first modification of the configuration is the thirdReference exampleInstead of displaying the importance level using a window of a color or shape corresponding to the degree of error, an importance level display unit 155 for indicating the importance level numerically is provided in each of the plurality of error windows 153 ′. The degree of importance is displayed by the numerical value of the degree display unit 155. The effect is the thirdReference exampleIt is the same.
[0070]
  FIG. 15 shows the thirdReference exampleIn the warning drawing regarding the second modified example of FIG. 3, the configuration uses an important error window 152 and a general error window 153.Reference exampleThe difference is that each window has a different size depending on the importance of the error. The effect is the thirdReference exampleIn addition to the effect of, important errors can be easily understood.
[0071]
  In FIG. 15, for example, when a warning is displayed in the critical error window 152 and the confirmation switch 154 in the critical error window 152 is operated, the warning message is canceled and the remaining warning messages are displayed. Among them, a warning message having the highest priority may be displayed in the important error window 152.
[0072]
  Even when the priority error window 152 is not preferentially processed, the warning is processed, the confirmation switch 154 is operated to delete the warning message, and the remaining unprocessed warnings are priorities. May be displayed in consideration of the above.
[0073]
  When displayed in this way, every time a warning is taken, if the confirmation switch 154 in that error window is operated, the message with the highest priority among the remaining warnings for which no warning is taken. Is displayed in the important error window 152.
[0074]
(FourthReference example)
  Next, the fourth of the present inventionReference exampleWill be explained. BookReference exampleIs the secondReference exampleIn addition to the above function, a message such as a warning is also given by voice.
  BookReference exampleIs a unit main body 35 'shown in FIG. 16 instead of the unit main body 35 of FIG.
[0075]
  The unit main body 35 ′ is further provided with a voice output unit 39 for outputting a voice message in the unit main body 35 of FIG. 8, and the voice output unit 39 is connected to the controller 15 via the control line 16.
[0076]
  FIG. 17 shows the configuration of the audio output unit 39. The control unit 39A reads the voice message data stored in the storage unit 39B by transmission from the controller 15, converts it into an analog voice signal through the D / A conversion unit 39C, and outputs it from the output unit 39D.
  Other configurations are secondReference exampleIt is the same.
[0077]
  That is, in addition to the sound output unit 39, the unit main body 35 ′ includes the light source unit 11, the electric knife unit 13, the suction pump unit 14, the video processor unit 12, and the full water detection unit 40 with the controller 15 via the control line 16. It is connected.
[0078]
  An operation input to the controller 15 is performed from the touch panel 18. Although not shown, the touch panel has a transparent matrix switch pasted on the surface of the color LCD. The touch panel is output in graphic form and the man-machine interface detects that the corresponding switch in the graphic is pressed. It constitutes.
[0079]
  The operation content input from the touch panel 18 is analyzed by the controller 15 and sent to the control line 16 as an operation command to control the functional units 11 to 14, 39 and 40.
  The electrosurgical unit 13 includes a P-code detection unit 13A that is an electrode on the patient side, an S-code detection unit 13B that collects current on the scope side, and an output abnormality detection unit 13C that detects an output abnormality. The information on the unconnected state, the unconnected state of the S code, and the output abnormality is transmitted to the controller 15 via the control unit 13D.
[0080]
  The video printer 36 connected to the outside of the unit main body 35 ′ has a paper jam detection unit 36 </ b> A, and when a paper jam occurs, the control unit 36 </ b> B transmits it to the controller 15.
[0081]
  Next, referring to FIG.Reference exampleThe main operation of will be described. In the program of the controller 15, it is assumed that a warning is periodically checked. The reception routine is shown in FIG. In the first step S11, it is first determined whether or not there are a plurality of warning receptions. If the number of warnings is one, that is, a single number, a message is visually displayed on the touch panel 18 as shown in step S12, and then the type of warning is further transmitted to the audio output unit 39 as shown in step S13. Then, a voice message is output from the voice output unit 39 to give an audible warning.
[0082]
  If there are a plurality of warnings, the priority order is determined by searching the priority file as shown in step S14. After this priority determination process is performed, the process proceeds to the next step S15. Then, the highest priority warning message is output to the touch panel 18, and the highest priority warning message is visually displayed.
[0083]
  Further, as shown in step S16, according to the priority order, the type of warning is transmitted to the voice output unit 39, and a voice message is output from the voice output unit 39. The system waits for this voice message output period or the warning message display period on the touch panel 18 (step S17), and then determines whether or not the process ends (step S18). Return to, and if finished, end the processing of this warning message.
[0084]
  The warning display displayed on the touch panel 18 is erased at an appropriate timing (not shown), or overwritten when the next priority order is displayed.
  As a method for determining the priority order, for example, a warning for safety may be given a higher priority than other general warnings. That is, in general, trouble related to the output of the electric knife 13 is more important for safety than paper jam of the video printer 36, full detection of the suction bottle, and the like. In this case, the voice message is terminated once, but it goes without saying that the message may be periodically circulated until the warning is resolved.
[0085]

  In the present embodiment, the above configuration is used. However, any configuration may be added to the configuration as long as it is used during an endoscopic procedure.
[0093]
  A power supply line 64 connected to a power supply (not shown) is connected to the main switch 61. When the main switch 61 is turned on, power is supplied to the touch panel 59 and the state detection device 60 via the power supply line 64. It is connected to the power supply line 64_1 of the computer 58 via the first relay 71 connected to the line 64. When the first relay 71 is turned on, power is supplied to the computer 58.
[0094]
  The power supply line 64 is connected to power supply lines 64_2 to 64_6 of endoscope peripheral devices denoted by reference numerals 52 to 56 through second to sixth relays 72 to 76, respectively. When 76 is ON, power is supplied to each device.
[0095]
  That is, the power supply line 64 is connected to the power supply line 64_2 of the light source unit 52 through the second relay 72, and power is supplied to the light source unit 52 when the second relay 72 is ON. The third relay 73, the fourth relay 74, the fifth relay 75, and the sixth relay 76 are a power line 64_2 of the video processor unit 52, a power line 64_3 of the CRT 54, and a power line 64_5 of the electric knife unit 55, respectively. The power is supplied to the endoscope peripheral devices connected to the power supply line 64_6 of the suction pump unit 56 and connected to the ON relay.
[0096]
  The reset switch 62 is connected to a terminal for ON / OFF control of the first relay 71 connected to the power supply line 64_1 of the computer 58 via the control signal line 65_1. When the reset switch 62 is pressed, the computer 58 is set for a predetermined time. Then, the computer 58 is turned off and the computer 58 is energized again to reset the computer 58.
[0097]
  The computer 58 is connected to terminals for ON / OFF control of the second to sixth relays 72 to 76 via control signal lines 65_2 to 65_6, and the second to sixth relays 72 to 76 are controlled by a control signal from the computer 58. ON / OFF of each of the endoscope peripheral devices can be controlled.
[0098]
  The state storage device 60 is connected to the control signal lines 65_2 to 65_6 connected to the second to sixth relays 72 to 76, respectively, and the signal states of the control signal lines 65_2 to 65_6 (more specifically, The state of the control signal for turning on / off the second to sixth relays 72 to 76 or the state of whether or not the endoscope peripheral device is energized) is stored again at regular intervals.
[0099]
  Information stored in the state storage device 60 is transmitted to the computer 58 via the state transmission lines 66_2 to 66_6.
  Further, the computer 58 transmits to the state storage device 60 through the signal line 67 whether the computer 58 is being started up or has been started up.
[0100]
  Further, the endoscope operator can centrally control the peripheral devices and the like constituting the endoscope apparatus 50A by operating the touch panel 59.
[0101]
  FIG. 21 shows the internal configuration of the state storage device 60.
  The power monitor circuit 81 is connected to the power line 64 and monitors whether the power is ON or OFF, and its output is input to the AND circuit 82. The AND circuit 82 is connected to a signal line 67, and a signal indicating whether the computer 58 is being started up or has been started up is input. Further, a clock from the clock generation circuit 83 is input to the AND circuit 82, and this clock is a signal for performing the timing of updating the state storage of the state storage device 60.
[0102]
  The output of the AND circuit 82 is applied to the clock input terminals C of the five flip-flops 84_2 to 84_6 forming the storage elements of the state storage device 60, and the computer 58 is in the start-up completion state and the power supply by the power supply monitoring circuit 81 is turned on. In the determination state, it is connected to the data input terminal D of each of the flip-flops 84_2 to 84_6 according to the cycle of the clock, latches the signal state of the control signal lines 65_2 to 65_6, and information corresponding to the state latched from the output terminal Q, Specifically, the binarized signal is output to the computer 58 via the status transmission lines 66_2 to 66_6.
[0103]
  Thus, the storage element is driven by the output of the AND circuit 82. Therefore, after a certain period of time after the main switch 61 is turned on, after the computer 58 is completely started up, the state storage device 60 is in an operating state (signal state storage and transmission of the stored signal state to the computer 58). It has become.
[0104]
  Next, the operation of the present embodiment will be described.
  First, the operator turns on the main switch 61 of the endoscope apparatus 50 </ b> A to energize the computer 58 from the power supply circuit, and starts up the computer 58.
[0105]
  At this time, the computer 58 is raising the signal state of the signal line 67 (more specifically, the signal state of “L”).
  Further, when the main switch 61 is turned on, the power source of the state storage device 60 is also turned on. The output of the power supply monitoring circuit 81 is also an output corresponding to turning on the power supply (more specifically, an “H” level output).
[0106]
  At this time, the AND circuit 82 is disabled so as not to output a clock due to information from the signal line 67 (more specifically, an “L” level signal), and the flip-flops 84_2 to 84_6 as the memory elements are initialized. The state (the output of the output terminal Q is “L” level) is maintained.
[0107]
  When the computer 58 starts up, the computer 58 puts the signal line 67 into a state indicating completion of startup (more specifically, a signal at the “H” level).
[0108]
  Then, the AND circuit 82 is enabled to pass the clock of the clock generation circuit 83, and the control signal lines 65_2 to 65_2 of the second to sixth relays 72 to 76 are connected to the flip-flops 84_2 to 84_6 as storage elements every time the clock is generated. The state of 65_6 is stored.
  When the computer 58 is started up, all the endoscope peripheral devices are turned off.
[0109]
  After confirming that the connector 80 of the endoscope 51 is correctly connected to the light source unit 52 and the video processor unit 53, the operator operates the touch panel 59 to turn on the light source unit 52 and the video processor unit 53. Then, examinations such as diagnosis and treatment are started using the endoscope 51.
[0110]
  The operator can operate the devices in the endoscope apparatus 50A by operating the touch panel 59 as necessary during the endoscope operation.
  When it becomes necessary to perform the reset operation of the computer 58 for some reason during the endoscope operation, the operator presses the reset switch 62 to reset the computer 58.
[0111]
  When the reset switch 62 is pressed, the power of the computer 58 is temporarily turned off and a reset operation is started after re-energization. At this time, the signal line 67 is in a state where the computer is starting up (more specifically, a signal state of “L” level). For this reason, the clock is disabled not to pass through the AND circuit 82. Therefore, the information stored in the flip-flops 84_2 to 84_6 holds the information before the reset switch 62 is pressed.
[0112]
  When the resetting of the computer 58 is completed, the computer 58 inputs the state of the control signal lines 65_2 to 65_6 and operates the state of the endoscope peripheral device based on the state. For example, when the light source unit 52 is reset in a used state, the light source unit 52 is maintained in the ON state during the reset, and the light source unit 52 is started in the ON state even after the reset is completed. That is, the ON state is maintained.
[0113]
  Thereafter, the state of the signal line 67 is changed to a state indicating completion of the computer startup, the AND circuit 82 is opened to enable the clock output, and information rewriting of the flip-flops 84_2 to 84_6 is enabled.
  Thereby, the reset of the entire endoscope apparatus 50A is completed.
[0114]
  The present embodiment has the following effects.
  By using the endoscope device 50A, when the endoscope device 50A is reset in a state where the light source unit 52 and the video processor unit 53 are used, the light source unit 52 and the video processor unit are completed when the reset is completed. Since it starts up with the power source 53 turned on, the operability when resuming the endoscopic examination is improved.
[0115]
  In this embodiment, the control of the power supply state of the endoscope peripheral device has been described. However, the information controlled by the method of this embodiment is any information that controls the state of each device. It doesn't matter.
  Further, not only the operator resets but also a reset when a monitoring circuit such as a watchdog timer detects an abnormality may be used.
[0116]

In addition, since the device can be reset without turning off the power source of the computer 58 (for example, a hard disk drive, a floppy (R) disk drive, etc.), a highly reliable operation can be performed.
[0120]
  Other effects areFirstThis is the same as the embodiment.
[0121]

[0125]
  The computer 58 is connected to the state storage device 86 via operation signal lines 88_2 to 88_6 for transmitting operation signals, and inputs the operation signal to the state storage device 86. Further, the computer 58 is connected to the state storage device 86 via a signal line 67 for transmitting whether the computer 58 is being started up or has been started up.
  The touch panel 59 is connected to the computer 58.
[0126]
  FIG. 24 shows the configuration of the state storage device 86 in the present embodiment.
  The output terminal of the timer circuit 89 is connected to the input terminal of the four-input logic element 90, which is connected to the reset switch 62 and is reset for a predetermined time when a reset signal is input. .
[0127]
  In addition to the output terminal of the timer circuit 89, the logic element 90 is connected to the clock output terminal of the clock generation circuit 83, the signal line 67, and the output terminal of the power supply monitoring circuit 81. True) A clock is output only when the main switch 61 is ON (power supply monitoring true), and the clock input terminals of the flip-flops 84_2 to 84_6 as the respective memory elements of the memory blocks 92 to 96 connected to the output terminals of the logic element 90 Applied to C to update the stored contents. In other cases, information of each storage element is retained. That is, the logic element 90 is a logic element for controlling whether or not data rewrite of the flip-flops 84_2 to 84_6 is possible.
[0128]
  The output terminal of the timer circuit 89 and the signal line 67 are connected to the input terminal of the second input logic element 91 having two inputs, and the output of the logic element 91 is output from the three-state buffers 97_2 to 97_6 in the storage blocks 92 to 96. Applied to the control terminals 98_2 to 98_6.
[0129]
  The second logic element 91 controls the three-state buffers 97_2 to 97_6 and 98_2 to 98_6 for selecting relay control signals output via the relay control lines 87_2 to 87_6 for controlling the second to sixth relays 72 to 76. A logic element that generates a signal, and outputs true when the reset is true and when the computer startup is complete.
[0130]
  Further, the output of the timer circuit 89 is connected to the control end of the first relay 71 via the relay control line 87_1, and when the reset switch 62 is operated, the first relay 71 is turned off for a predetermined time to reset the computer 58. .
[0131]
  In the memory block 92, the data input terminal D of the flip-flop 84_2 is connected to the operation signal line 88_2 from the computer 58 and to the input terminal of the three-state buffer 98_2.

[0132]
  When the logic element 91 outputs true, the 3-state buffer 97_2 is turned on, and the stored information of the flip-flop 84_2 is output via the signal line 87_2. When the logic element 91 outputs false, the three-state buffer 98_2 is turned on, and the operation signal of the operation signal line 88_2 connected to the computer 58 is output via the signal line 87_2.
[0133]
  Since the other storage blocks 93 to 96 have substantially the same configuration, the description thereof is omitted.
  Other configurations areSecondThis is the same as the embodiment.
  Next, the operation of this embodiment will be described.
[0134]
  When the computer 58 is in operation, the operation signal of the computer 58 is updated and stored in the flip-flops 84_2 to 84_6 as the respective storage elements by the clock passed through the logic element 90, and this operation signal is stored in the three-state buffer. It is applied to the control terminals of the relays 72 to 76 through 98_2 to 98_6, and the operation of the endoscope peripheral devices 52 to 56 (power supply ON / OFF) can be controlled under the control of the computer 58.
[0135]
  When the reset signal is generated by operating the reset switch 62 in a state where the computer 58 has to be restarted, the power supply to the computer 58 is turned off for a certain period by the output of the timer circuit 87, and the computer 58 is reset. At the same time, the logic element 90 does not pass the clock, and each storage element stores the state of the operation signal immediately before the reset.
[0136]
  When the computer 58 has not been started up, the other logic element 91 turns on the three-state buffers 97_2 to 97_6 and applies the storage information of each storage element to the relays 72 to 76 via the relay control lines 87_2 to 87_6. Then, the ON / OFF state of the relays 72 to 76 (that is, the operation / non-operation state of the endoscope peripheral devices 52 to 56) is maintained in the state before the reset operation.
[0137]
  For example, during an endoscopy, the light source unit 52, the video processor unit 53, and the CRT 54 are in an operating state in which power is supplied, and even when the computer 58 is not completely started up by a reset operation, The operation state of the endoscope peripheral device (more specifically, a state in which an endoscope image is displayed on the CRT 54 by the endoscope 51) is maintained.
[0138]
  Further, the storage information of each storage element is sent to the computer 58 via the state transmission lines 66_2 to 66_6. Therefore, before the start-up is completed, the computer 58 sets the state of the operation signal to the storage information of each storage element sent via the state transmission lines 66_2 to 66_6, and then makes the start-up complete state. Immediately after the start-up is completed, the operation state of the endoscope peripheral device is maintained in the state before the reset operation, and thereafter it is controlled again under the control of the computer 58.
[0139]
