Drive it. The second driver 34 drives a solenoid valve 52 such as a lifting mechanism that adjusts the height of the examination table and a tilting mechanism that adjusts the angle of the back mat with respect to the waist mat according to a control signal supplied from the control circuit 30. Let The third driver 36 responds to the control signal supplied from the control circuit 30 by the second input unit 2
The predetermined light emitting diodes 44c to 44j provided in
(Indicated by generic reference numeral 44 in FIG. 2).

During standby, the examination table 12 is oriented in a predetermined direction, the examination table 12 and the crotch support 12c are lowered, and the back mat 12b is raised. In addition, any one of the memory keys 40f to 40j is enabled,
The light emitting diode corresponding to the memory key is turned on.

At the time of examination, after the patient sits on the examination table 12, the start switch of the first input unit 22 is stepped on by the doctor or nurse, and the start command is input to the control circuit 30. This causes the control circuit 30 to start operating.

The control circuit 30 firstly, the rotation angle of the examination table about the vertical axis, the height of the waist mat, which is stored in the storage section corresponding to the memory key that is valid,
Read back mat angle and crotch support height. Next, the control circuit 30 supplies a control signal for displacing the examination table 12 to the read rotation angle to the first driver 32. As a result, the examination table 12 is rotated about the vertical axis by a predetermined angle and is oriented in a predetermined direction. Next, the control circuit 30 supplies the control signal for raising the waist mat 12a to the read height and the control signal for inclining the back mat 12b to the read angle to the second driver 34, and A control signal for raising the receiver 12c to the read height is supplied to the first driver 32.

As a result, the waist mat 12a and the crotch support 12c are raised to a predetermined height, and the back mat 12b is tilted to a predetermined angle, so that the patient on the examination table 12 is placed in a predetermined supine position, It is put in a prescribed examination state.

When the end switch of the first input unit 22 is stepped on, the control circuit 30 controls the examination table 12 and the back mat 1.
A predetermined control signal for returning 2b and the crotch support 12c to the initial state is supplied to the first and second drivers 32, 34. As a result, the examination table 12 and the crotch support 12c are lowered, the back mat 12b is raised, and the examination table 12 is oriented in the original direction.

When another switch of the first input unit 22 is stepped on, the control circuit 30 outputs a control signal corresponding to the stepped switch while the switch is stepped on.
Alternatively, it is supplied to the second driver 32 or 34. As a result, the examination table 12 is raised, the examination table 12 is lowered, the back mat 12b is tilted, the back mat 12b is returned, the crotch support 12c is raised, and the crotch support 1 according to the stepped switch.
Either of the descending of 2c is performed.

The set value of the rotation angle of the examination table 12 around the vertical axis, that is, the set value of the rotation angle from the reference position is displayed on the display 42 of the second input unit 24. To generate a melody (in melody mode)
If set, the control circuit 30 sends a melody generation command to the melody generator 38 while the examination table 12 is displaced.
To produce a melody.

Next, the operation of the control circuit when the key of the second input unit 24 is depressed will be described with reference to FIGS.

Of the command keys of the second input unit 24, the command keys other than the cancel key 40c are always in the invalid or key lock mode even when pressed.
Therefore, even if any command key other than the release key 40c is mistakenly pressed, the examination table 12 does not operate. That is, the command keys of the second input unit 24 may be unintentionally erroneously pressed by the patient other than the doctor and the nurse. If each command key is valid, that is, if it is always in the key lock release mode, it is dangerous because the patient erroneously presses down one of the command keys during the medical examination and the examination table operates. . However, if each command key is always in the key lock mode, even if a patient or the like erroneously presses down any command key during a medical examination, the examination table does not operate, which is safe.

As shown in FIG. 4, when the release key 40c is depressed, the control circuit 30 puts the keys of the second input unit 24 in the key-lock release state (step 1).
01), it is determined whether or not a fixed time, for example, 3 seconds has elapsed since the release key 40c was pressed (step 10).
2). When 3 seconds have passed as a result of the determination in step 102, the control circuit 30 sets each key of the second input unit 24 to the invalid state, that is, the key lock state, and turns off the light emitting diode 44c corresponding to the release key 40c. After being in the state (step 103), it returns to the standby state. Therefore, each key of the second input unit 24 is put in the key-locked state again, and the safety is enhanced. Step 10
If the result of the determination in 2 is that 3 seconds have not elapsed, the control circuit 30 determines whether or not another key has been pressed (step 104). If the result of this determination is that no other key has been pressed, the control circuit 30 returns to step 102.
Therefore, if another key is not pressed within a fixed time after the release key 40c is pressed, the control circuit 30 returns to the standby state after executing step 103, and each key of the second input unit 24 is again pressed. It is placed in the key lock state, improving safety. If the result of determination in step 104 is that another key has been pressed, the control circuit 30 performs processing corresponding to the pressed key (step 10).
5) It is determined whether or not a certain time, for example, 3 seconds has elapsed since the other keys were pressed (step 10).
6). The control circuit 30 returns to step 104 if the fixed time has not elapsed as a result of the determination in step 106, but if the fixed time has elapsed, executes the step 103 and then returns to the standby state. Therefore, it is possible to input control commands one after another with a plurality of command keys within a fixed time after pressing the other keys. If another key is not pressed within a certain time after the other key is pressed, each command key is put in the key-locked state again, and the safety is enhanced.

As shown in FIG. 5, when the large angle key 40a is depressed, the control circuit 30 determines whether or not the key lock is released (step 107). If the result of this determination is that the key lock has not been released, the control circuit 30
Returns to the standby state. However, step 107
When the key lock is released as a result of the determination in
The control circuit 30 counts the set value of the rotation angle of the examination table 12 around the vertical axis in the up state (step 108), and then returns to the standby state. This corrects the set value of the rotation angle of the examination table 12 around the vertical axis.

As shown in FIG. 6, when the small angle key 40b is depressed, the control circuit 30 determines whether or not the key lock is released (step 109). If the result of this determination is that the key lock has not been released, the control circuit 30 returns to the standby state as it is. But step one
If the key lock is released as a result of the determination in 09, the control circuit 30 causes the examination table 1 around the vertical axis.
After counting the set value of the rotation angle of 2 in the down state (step 108), the process returns to the standby state. This corrects the set value of the rotation angle of the examination table around the vertical axis.

As shown in FIG. 7, when the melody key 40d is pressed down, the control circuit 30 determines whether or not the key lock is released (step 111). As a result of this determination, the control circuit 30 returns to the standby state as it is if the key lock is not released, but if the key lock is released, whether or not the melody mode is set to generate a melody. It is determined (step 112). If the result of determination in step 112 is that the melody mode is not set, the control circuit 30
The melody mode is set (step 113), the light emitting diode 44d corresponding to the melody key 40d is turned on (step 114), and then the standby state is returned to. If the result of determination in step 112 is that the melody mode has been set, the control circuit 30 sets so as not to generate a melody, that is, the non-melody mode (step 115), and turns on the light emitting diode 44d corresponding to the melody key 40d. After putting it off (Step 11)
6) Return to the standby state.

As shown in FIG. 8, the update mode key 40e
When is depressed, the control circuit 30 determines whether or not the key lock is released (step 117). If the result of this determination is that the key lock has not been released, the control circuit 30 returns to the standby state as is, but if the key lock has been released, the control circuit 30 is set to the updatable mode, that is, the update mode. It is determined whether or not (step 118). If the result of determination in step 118 is that the update mode has not been set, the control circuit 30 sets the update mode (step 119) and the update mode key 4
After the light emitting diode 44e corresponding to 0e is turned on (step 120), it returns to the standby state. Step 1
As a result of the determination in 18, if the update mode is set, the control circuit 30 returns to the standby state as it is. As will be described later, the light emitting diode 44e is turned off and the update mode is released (set to the non-update mode) during the processing when any one of the memory keys 40f to 40j is pressed.

As shown in FIG. 9, memory keys 40f-4f
When any one of 0j, for example, the memory key 40f is pressed, the control circuit 30 determines whether or not the key lock is released (step 121). As a result of this judgment,
If the key lock is not released, the control circuit 30 returns to the standby state as it is, but if the key lock is released, the control circuit 30 determines whether or not the update mode is set (step 122). As a result of the determination in step 122,
If the update mode is not set, the control circuit 30 determines that the information to be read when the start switch of the first input unit 22 is pressed is the information in the storage unit (memory-1) corresponding to the memory key 44f. Is set (step 123), the light emitting diode 44f corresponding to the memory key 40f is turned on (step 124),
Return to the standby state. As a result of the determination in step 122,
When the update mode is set, the control circuit 30 updates the information in the storage unit (memory-1) corresponding to the memory key 44f to the current value supplied from the measuring device 26 (step 125), and updates. After the mode is canceled (set to the non-update mode), the light emitting diode 44e corresponding to the update mode key is turned off (step 126), and the light emitting diode 44f corresponding to the memory key 44f is turned on (step 127). , Return to the standby state. As a result, the information in the storage unit (memory 1) corresponding to the memory key 44f is supplied from the measuring device 26 to the control circuit 30, the rotation angle of the examination table, the height of the waist mat, the angle of the back mat, and the angle of the back mat. It is updated to the current value of the crotch height.
When any one of the other memory keys 44g, 44h, 44h, 44i and 44j is pressed down, except that the processing of the storage section and the light emitting diode corresponding to the memory key is performed in steps 123 to 127 shown in FIG. Then, the control circuit 30 executes steps 121 to 127 described above. Therefore, the doctor is
After the patient is placed in the optimal supine state and the optimal examination state by any of the foot switches, the release key 40c is pressed down, the update key 40e is pressed down, and then the memory key 40f is pressed.
By depressing any one of ˜40j, it is possible to set an optimal posture for oneself.

The update mode key 40e is used as a means for outputting a command for updating the information in the storage unit, instead of allowing the update of the information in the memory unit to be updated, and the update command is output. As a result, the information in the storage section specified by the storage section designation signal may be updated to the current value output from the measuring device. Also, the rotation angle of the examination table around the vertical axis is always the same when the examination device and its installation location are determined, even if the doctors using the examination device are different, so the rotation angle of the examination table is always the same. Therefore, the predetermined rotation angle may be stored or set in a specific storage unit or other means. Further, the height of the crotch support does not have to be different for each doctor. A command key corresponding to each foot switch of the first input unit 22 may be provided in the second input unit or in the second input unit.
