Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for controlling a displaceable examination table, and more particularly to a control apparatus suitable as an apparatus for controlling the displacement of an obstetrics and gynecology examination table.

[0002]

2. Description of the Related Art A medical examination apparatus for obstetrics and gynecology generally comprises a medical examination table having a waist mat for receiving the patient's waist and a back mat for receiving the patient's back, and an examination table for adjusting the height of the patient to a doctor. An elevating mechanism that elevates and lowers, a rotating mechanism that rotates the examination table angularly around the vertical axis to adjust the orientation of the patient with respect to the doctor, and a back mat to the waist mat to keep the patient in a supine position at any angle. And a tilting mechanism for tilting at an arbitrary angle (for example, Japanese Patent Laid-Open No. 3-49462 and Japanese Utility Model Laid-Open No. 3-40995).

During the examination, when the patient sits on the examination table, the examination table is directed from the changing room side to the doctor side. Then
The examination table is raised to a predetermined height to keep the patient at a predetermined height, and the back mat is tilted at a predetermined angle with respect to the waist mat to keep the patient in a supine position at an arbitrary angle. In this state,
A medical examination will be conducted. When the examination is completed, the back mat is raised, the examination table is lowered, and the examination table is directed to the initial position. Optimal values of the height of the examination table and the angle of the back mat with respect to the waist mat at the time of examination differ depending on the doctor.

Various controls for driving the elevating mechanism, the rotating mechanism and the tilting mechanism are performed by a control device using a plurality of foot switches and the like. These foot switches are used as first input means for inputting various control commands for displacing the examination table, such as a drive command for displacing the examination table, a start command for the examination, and an end command for the examination, to the control circuit of the control device. And is assembled into one input unit and is movably arranged on the floor.

The control device also issues various other control commands such as a command for setting initial values such as the height of the examination table, a rotation angle of the examination table, and an angle of the waist mat, and a command for correcting the initial values. It has a plurality of key switches or command keys to generate. These command keys are used as second input means for inputting the above-mentioned other commands to the control circuit,
It is also provided on the operation panel of the medical examination device.

The control device inputs the start command to the control circuit so that the height of the examination table (height of the waist mat) and the angle of the back mat with respect to the waist mat become the predetermined initial values. Displacement of the examination table and the drive command is input to the control circuit, so that the examination table is displaced according to the drive command and the operation command is input to the control circuit. The examination table is returned to the original state by operating the table and inputting the end command to the control circuit.

However, in the conventional control device, since the examination table is only displaced by the switch of the first input means, the first input means or the means for connecting the first input means and the examination table is provided. If it fails, the examination table cannot be displaced. In particular, when a pregnant woman is supine on the examination table and the examination table fails to be displaced, a large force acts on the abdomen of the pregnant woman when the pregnant woman in the supine state is raised by human power on the examination table. And dangerous.

In order to solve the above-mentioned problems, if a key switch having the same weight as each switch of the first input means is further provided on the examination table, the number of switches increases and the examination apparatus becomes complicated. . Further, not only the doctor and the nurse but also the patient may unintentionally operate the key switch by mistake. In this case, the examination table is displaced even during the examination, which is dangerous.

Further, in the conventional control device, the inspection table must be displaced by using the foot switch of the first input unit during maintenance / inspection, which is troublesome for maintenance / inspection work.

Further, in order to improve safety, the examination apparatus generally measures the amount of displacement of the examination table and limits the displaceable range of the examination table by the foot switch of the first input unit. When the measuring means fails, the examination table cannot be displaced by the foot switch of the first input unit. Therefore, in the conventional control device, the examination table cannot be displaced beyond the allowable range by the foot switch of the first input unit, and the examination table can be displaced if the displacement amount measuring means fails. Therefore, maintenance and inspection work is troublesome.

[0011]

SUMMARY OF THE INVENTION It is an object of the present invention to provide safety even though the examination table can be displaced by a switch other than the switch of the first input means.

[0012]

According to the present invention, there is provided a first input means including a plurality of weighted first switches corresponding to a command for displacing a medical examination table, which is a location apart from the medical examination table. And a second input means provided with a plurality of weighted second switches corresponding to a command to operate the examination table, the second input means being provided on the examination table.

Usually, the second switch is given its original weight. Therefore, the examination table is displaced according to the operated first switch when the first switch is operated, and the operated second switch is operated when the second switch is operated. Works according to.

However, when a plurality of specific second switches are simultaneously operated, the weight of the second switch is changed from its original weight to another weight that displaces the examination table. Therefore, thereafter, by operating the second switch, the second switch is displaced according to the operated second switch.

As described above, according to the present invention, the examination table is constructed by the second switch having a weight different from that of the first switch without specially providing another switch having the same weight as that of the first switch. It can be displaced.

Further, unless a specific plurality of second switches are simultaneously operated, the weight of the second switch is not changed from its original weight to another weight, and the weight of the second switch is changed. Since the examination table will not be displaced unless the second switch is operated later,
The probability that the second switch is erroneously operated by the patient or the like and the probability that the second switch is operated after the weight of the second switch is changed are small, and therefore the probability that the examination table is displaced by the erroneous operation of the patient or the like is significant. Small and safe.

The other weight may be the same as the weight attached to the first switch, or the first weight may be the same.
The weight may be different from the weight assigned to the second switch.

The weight of the second switch is changed from the original weight to the other weight because the specific plurality of second switches are simultaneously and continuously operated for a predetermined time. It is preferable. As a result, the probability that the weight of the second switch is changed from the original weight to another weight due to an erroneous operation by the patient becomes very small,
Safer.

It is preferable that the weights of the second switches are returned to the original weights by maintaining the specific plurality of second switches simultaneously and continuously operated for a certain period of time. As a result, due to an erroneous operation by the patient,
Even if the specific plurality of second switches are continuously maintained in the state of being simultaneously operated, the weight of the second switch is temporarily changed to another weight. Since the weight of the switch of 2 is returned to the original weight,
Safer.

By the fact that the specific plurality of second switches consisting of the combination of the second switches other than the combination of the specific plurality of second switches are simultaneously maintained in a continuously operated state for a certain period of time, The weight of the second switch may be returned to the original weight.

By simultaneously operating the specific plurality of second switches, the weight of the second switch is changed from the original weight to the weight assigned to the first switch, and the specific weight of the second switch is changed. A plurality of second switches of a combination other than the combination of the plurality of second switches of the second switch are maintained at the same time continuously operated for a certain period of time. May be changed from the original weight to a weight different from the weight given to the first switch.

By the fact that the specific plurality of second switches consisting of the combination of the second switches other than the combination of the specific plurality of second switches are simultaneously maintained in a continuously operated state for a fixed time, The weight of the second switch may be returned to the original weight.

Further, a measuring means for measuring a current value of the displacement amount of the examination table and outputting a corresponding electric signal is provided, and the current value is inputted to the control means, and the control means is provided for the first means. Upon receiving a command from the switch, the examination table is displaced within the allowable range of the current value,
After changing the weight of the switch from the original weight to the other weight, it is possible to displace the examination table by ignoring the allowable range of the present value by a command from the second input means. preferable. Thereby, the examination table can be displaced beyond the allowable range.

The display 42 is a known one that displays a number by a plurality of segments, and can display a three-digit number in the illustrated example. Each of the light emitting diodes 44c to 44j is turned on while the corresponding key 40c to 40j is valid. The rotation direction indicator lamp 46 is turned on according to the set rotation direction.

The measuring device 26 uses the ultrasonic wave and the laser beam for the current values of the rotation angle of the examination table about the vertical axis, the height of the examination table, the angle of the back mat with respect to the waist mat, and the height of the crotch support. Sensor 46 and a measurement circuit 48 that processes the output signal of the sensor, and the measured current value is input to control circuit 30.

The first driver 32 drives an electric motor 50 such as a rotating mechanism for rotating the examination table around a vertical axis and a vertical moving mechanism for vertically moving the crotch support according to a control signal supplied from the control circuit 30. Drive it. The second driver 34 drives the solenoid valve 52 such as a lifting mechanism for adjusting the height of the examination table and a tilting mechanism for adjusting the angle of the back mat with respect to the waist mat according to the 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).

In the examination table 12, normally, the weight of each command key of the second input unit 22 is the original weight thereof, that is, the second weight.
Is set to the weight of (examination possible mode, that is, examination mode is set).

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 the 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 around the vertical axis, the height of the waist mat, which is stored in the storage section corresponding to the valid memory key,
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
Are rotated about the vertical axis by a predetermined angle and oriented in a predetermined direction.

Next, the control circuit 30 controls the waist mat 12a.
Is supplied to the second driver 34, and a control signal for raising the back mat 12b to the read height and a control signal for inclining the back mat 12b to the read angle are raised to the read height. And supplies a control signal 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 at 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 causes the examination table 12 and the back mat 1 to move.
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 the 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 raised, the back mat 12b is lowered, 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 can be corrected by the command keys 40a and 40b, as will be described later. It is displayed on the display 42 of the input unit 24. If it is set to generate a melody (melody mode), the control circuit 30 supplies a melody generation command to the melody generator 38 while the examination table 12 is displaced, whereby the melody is generated.

As described above, in the examination mode, the first
When the foot switch of the input unit 22 is stepped on, the processing by the first weight attached to the foot switch is performed, and when the command key of the second input unit 24 is depressed, the original command key The processing is performed by the second weight which is the weight of.

However, if the weight of the command keys 40a to 40j is changed to the weight of the foot switch of the first input unit 22 (when the help mode is set), the command key of the second input unit 24 is changed. By pressing down, the processing with the first weight corresponding to the command key is performed.

If the weight of the command keys 40a to 40j is changed to a third weight different from the first and second weights (when the back mode is set), the second input unit 24 is selected. By pressing down the command key of No. 3, processing by the third weight corresponding to the command key is performed.

The first and third weights correspond to drive commands for actually displacing the examination table. On the other hand, the second weight is a numerical value used when displacing the examination table,
Supports control commands such as settings, corrections, and updates.

In the examination mode, the examination table is displaced within the allowable range by the control circuit 30 using the present value supplied from the measuring device 26 to the control circuit 30 and the preset allowable limit value. . As a result, the safety at the time of examination is maintained.

On the other hand, in the back mode, the examination table can be displaced beyond the allowable range, that is, ignoring the allowable limit value. Therefore, maintenance,
At the time of inspection, repair, adjustment, etc., the examination table can be largely displaced with the back mode set, which facilitates maintenance and inspection work.

When the help mode is set, the command keys 40a and 40b are treated as invalid even if they are pressed. On the other hand, command keys 40c-4
The weights of 0j are respectively those of the end switch, start switch, crotch support lowering switch, base raising switch, back mat lowering switch, crotch support raising switch, base lowering switch and back mat raising switch of the first input unit. Weight, that is, end command, start command, crotch support lowering command, platform raising command, back mat lowering command, crotch receiving raising command,
It is possible to use weights corresponding to the platform lowering command and the back mat raising command.

Even when the back mode is set, even if the command keys 40a and 40b are pressed down, they are treated as invalid. On the other hand, command keys 40c-4
The weights of 0j are respectively a table lowering command for lowering the examination table, a table raising instruction for raising the examination table, a table left rotation instruction for rotating the examination table counterclockwise, a back mat raising instruction for raising the back mat, and a crotch support raising. It is possible to use weights corresponding to the crotch support rising command, the table right rotation command for rotating the examination table to the right, the back mat lowering command for lowering the back mat, and the crotch receiver lowering command command for lowering the crotch support.

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.

The switching of the weight of the command key is executed by pressing down two specific command keys at the same time.
In the illustrated example, when the command keys 40a and 40b are pressed simultaneously, the help mode is set or released. On the other hand, when the command keys 40b and 40e are pressed at the same time, the back mode is set or released.

As shown in FIG. 4, when the large angle key 40a and the small angle key 40b are pressed at the same time, the control circuit 30
Is set to help mode (command key 40
It is determined whether the weights of a to 40j are switched to the weight of the foot switch of the first input unit 22, that is, whether the weight is switched to the first weight (step 100).

Next, the control circuit 30 proceeds to step 100.
Regardless of the result of the judgment in, the large angle key 4
0a and the small angle key 40b are simultaneously pressed, and it is determined whether or not the state continues for a predetermined time, for example, 3 seconds (step 1
01 or 102), if it is not continued for a predetermined time, it returns to the standby state.

However, if the result of determination in step 101 is that 3 consecutive seconds have elapsed, the control circuit 30 causes the command key 4
The weight of 0a to 40j is changed to the first weight, that is, the help mode is set (step 103), and "H" is displayed on the numeral display 42 to inform that the help mode is set.
After displaying "LP" (step 104), the process returns to the standby state.

If the result of determination in step 102 is that 3 consecutive seconds have elapsed, the control circuit 30 causes the command key 4
The weight of 0a to 40j is returned to its original weight, that is, the second weight, that is, the help mode is released (step 1
05), after displaying the set value of the rotation angle of the examination table around the vertical axis on the numeric display 42 (step 10).
6) Return to the standby state.

When the first input unit 22 fails, the weight of the command key of the second input unit 24 is switched to the first weight as described above, and then the examination table 12 is moved to the second input unit. With the command key 24, the displacement can be performed as in the case of using the foot switch of the first input unit 22.

As shown in FIG. 5, when the small angle key 40b and the update mode key 40e are pressed at the same time, the control circuit 30 determines whether or not the help mode is set (step 110).

If the result of determination in step 110 is that the help mode has been set, the control circuit 30 returns to the standby state. However, if the help mode is not set, the control circuit 30 determines whether or not the back mode is set (whether or not the weights of the command keys 40a to 40j are changed to the third weight) (step). 111).

Next, the control circuit 30 causes the step 111
Angle small key 4
0b and the update mode key 40e are pressed at the same time and it is judged whether or not the state has continued for a predetermined time, for example, 3 seconds (step 112 or 113), and if not continued for the predetermined time, the process returns to the standby state.

However, if the result of determination in step 112 is that three consecutive seconds have occurred, the control circuit 30 causes the command key 4
The weights of 0a to 40j are changed to the third weight, that is, the back mode is set (step 114), and the rotation direction indicator lamp is blinked to notify that the back mode is set (step 115). Return to the standby state.

If the result of determination in step 113 is that 3 consecutive seconds have elapsed, the control circuit 30 causes the command key 4
The weights of 0a to 40j are returned to their original weights, that is, the back mode is canceled (step 116), and the numeral display 4 is displayed.
After the setting value of the rotation angle of the examination table around the vertical axis is displayed in 2 (step 117), the process returns to the standby state.

At the time of maintenance and inspection of the examination apparatus, after changing the weight of the command key of the second input unit 24 to the third weight as described above, the examination table 12 is moved to the second input unit 2.
It can be displaced by the command key of No. 4. At this time, the examination table can be displaced beyond the allowable range, which facilitates maintenance and inspection work.

As described above, when the help mode or back mode is set by operating a plurality of specific command keys at the same time, the probability that the specific command keys are erroneously operated simultaneously is small, and the safety is enhanced. .

If the same specific command keys are continuously pressed for a predetermined time and maintained in the depressed state, the help mode or back mode is set and released. Even if the specified plurality of command keys are continuously kept pressed down, the weights of the command keys are alternately changed to the first and second weights or the second and third weights. Because it is not too much, the safety is increased.

The release of the help mode or back mode may be executed by a command key other than the combination of command keys set to the help mode or back mode.

When the examination mode is set, the cancel key 40c of the command keys of the second input unit 24 is pressed.
Each command key except for is 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.

As shown in FIG. 6, when the release key 40c is depressed, the control circuit 30 determines whether or not the help mode is set (step 120). As a result of this determination, if the help mode is set, the control circuit 30
After performing a process of returning the examination table 12 to the initial state, by depressing the release key 40c, by depressing the end switch of the first input unit 22 (step 12).
1) Return to the standby state. Accordingly, when the help mode is set, the cancel key 40c is given the same weight as the end switch of the first input unit 22.

If the result of determination in step 120 is that the help mode has not been set, the control circuit 30 determines whether or not the back mode has been set (step 1
122). As a result of this determination, if the back mode is set, the control circuit 30 outputs a control signal for raising the crotch support, regarding that the release key 40c has been pressed down, as if the crotch support raising command was input. After (Step 12
3) Return to the standby state. As a result, when the back mode is set, the release key 40c acts as a crotch support raising switch.

If the result of determination in step 120 is that the back mode has not been set, the control circuit 30 determines whether or not the release key 40c has been depressed for a certain period of time, for example, 2 seconds (step 124). ).

If the result of determination in step 124 is that the release key 40c has not been pressed down for a certain period of time, the control circuit 30 returns to the standby state. But,
When the release key 40c is continuously pressed for a certain period of time, the control circuit 30 puts each key of the second input unit 24 into the key lock release state and turns on the light emitting diode 44c corresponding to the release key 40c. Turn on (Step 1
25). For this reason, unless the release key is maintained in the operating state continuously for a predetermined time, the key lock is not released, so that even if the command key is mistakenly operated, the examination table does not operate and it is safe.

Then, the control circuit 30 releases the release key 40c.
It is determined whether or not a predetermined time, for example, 3 seconds has elapsed after the pressure was reduced (step 126). If the result of this determination is that a certain period of time has elapsed, the control circuit 30 puts each key of the second input unit 24 in the key lock state and puts the light emitting diode 44c in the off state (step 112).
7) Return to the standby state. Therefore, when the release key 40c is continuously pressed in the examination mode, each key of the second input unit 24 is alternately repeated between the key-locked state and the key-locked released state, and safety is enhanced. .

If the result of the determination in step 126 is that 3 seconds have not elapsed, the control circuit 30 determines whether or not another command key has been pressed (step 128). As a result of this determination, if the other keys are not pressed down, the control circuit 3
0 returns to step 125. Therefore, the release key 40
If no other key is pressed within a fixed time after c is pressed, the control circuit 30 returns to the standby state after executing step 127, and each key of the second input unit 24 is again locked. The safety is improved.

If the result of determination in step 128 is that another key has been pressed, the control circuit 30 carries out processing corresponding to the pressed command key (step 129).
It is determined whether or not a predetermined time, for example, 3 seconds has elapsed since the other keys were pressed (step 130).

As a result of the determination in step 130, the control circuit 30 determines that step 1
Return to step 26, but if a certain time has passed, step 1
After executing 27, the process 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. 7, when the large angle key 40a is depressed, the control circuit 30 determines whether or not the help mode is set (step 140), and whether or not the back mode is set. It is determined (step 141)
Then, it is determined whether or not the key lock is released (step 142). As a result of these determinations, if the help mode is set, the back mode is set, or the key lock is not released, the control circuit 30
Processes the large angle key 40a as invalid even if the large angle key 40a is pressed.

However, if the result of determination in step 142 is that the key lock has been released, the control circuit 30
After counting the set value of the rotation angle of the examination table 12 around the vertical axis in the up state (step 143), the process returns to the standby state. Thereby, the set value of the rotation angle of the examination table 12 around the vertical axis is corrected.

As shown in FIG. 8, when the small angle key 40b is depressed, the control circuit 30 determines whether or not the help mode is set (step 150), and whether or not the back mode is set. It is determined (step 151)
Then, it is determined whether or not the key lock is released (step 152).

As a result of these judgments, it is determined whether the help mode is set, the back mode is set, or
If the key lock is not released, the control circuit 30 treats the small angle key 40b as invalid even if the small angle key 40b is pressed.

However, if the result of determination in step 152 is that the key lock has been released, the control circuit 30
After counting the set value of the rotation angle of the examination table 12 around the vertical axis in the down state (step 153), the process returns to the standby state. Thereby, the set value of the rotation angle of the examination table 12 around the vertical axis is corrected.

As shown in FIG. 9, when the melody key 40d is pressed down, the control circuit 30 determines whether or not the help mode is set (step 160). If the result of this determination is that the help mode has been set, the control circuit 30 indicates that the melody key 40d has been depressed.
After the start switch of the input unit 22 has been stepped on, the examination table 12 is displaced to a predetermined state (step 161), and then the state returns to the standby state. As a result, when the help mode is set, the melody key 40d
Are weighted the same as the starting switch of the first input unit 22.

If the result of determination in step 160 is that the help mode has not been set, the control circuit 30 determines whether or not the back mode has been set (step 1
622). As a result of this determination, if the back mode is set, the control circuit 30 outputs a control signal for raising the examination table, assuming that the melody key 40d is pressed down, as if the table raising command is input. (Step 16
3) Return to the standby state. As a result, when the back mode is set, the melody key 40d acts as a table raising switch.

If the result of determination in step 162 is that the help mode has not been set, the control circuit 30 determines whether or not the key lock has been released (step 1
64). As a result of this determination, the control circuit 30 returns to the standby state if the key lock is not released, but if the key lock is released, whether or not the melody is set, that is, the melody mode is set, is generated. Is determined (step 165).

If the result of determination in step 165 is that the melody mode has not been set, the control circuit 30 sets the melody mode (step 166) and after turning on the light emitting diode 44d corresponding to the melody key 40d (step 166). Step 167) returns to the standby state.

If the result of determination in step 165 is that the melody mode has been set, the control circuit 30 sets so that no melody is generated, that is, the non-melody mode (step 168), and the light emission corresponding to the melody key 40d. After the diode 44d is turned off (step 169), it returns to the standby state.

As shown in FIG. 10, the update mode key 40
When e is reduced, the control circuit 30 determines whether or not the help mode is set (step 170). If the result of this determination is that the help mode has been set, the control circuit 30 determines that the update mode key 40e has been pressed down, as if the crotch pad lowering switch of the first input unit 22 was stepped on. After performing the process of lowering the crotch support 12 (step 151), the process returns to the standby state. As a result, when the help mode is set, the update mode key 40e is given the same weight as the crotch support lowering switch of the first input unit 22.

If the result of determination in step 170 is that the help mode has not been set, the control circuit 30 determines whether or not the back mode has been set (step 1
722). As a result of this determination, if the back mode is set, the control circuit 30 regards that the update mode key 40e is pressed down as a table left rotation command is input, and outputs a control signal for rotating the examination table counterclockwise. After output (step 1
73) and returns to the standby state. Accordingly, when the back mode is set, the update mode key 40e acts as a table left rotation switch.

As a result of the determination in step 172, if the back mode is not set, the control circuit 30 determines whether or not the key lock is released (step 17).
4). As a result of this determination, the control circuit 30 returns to the standby state if the key lock is not released, but if the key lock is released, the control circuit 30 determines whether or not the update mode is set. (Step 175).

If the result of determination in step 175 is that the update mode has not been set, the control circuit 30 sets the update mode (step 176) and the update mode key 40
After the light emitting diode 44e corresponding to e is turned on (step 177), it returns to the standby state.

If the result of determination in step 175 is that the update mode has been set, the control circuit 30 returns to the standby state. As will be described later, the memory key 40f-
During processing when any one of 40j is pressed down, the light emitting diode 44e is turned off and the update mode is released (set to the non-update mode).

As shown in FIG. 11, memory keys 40f.about.
When one of the keys 40j, for example, the memory key 40f is pressed, the control circuit 30 determines whether or not the help mode is set (step 180). As a result of this determination, if the help mode is set, the control circuit 30
Indicates that the memory key 40f has been pressed down, and that the table raising switch of the first input unit 22 has been stepped on.
After performing the process of raising the examination table 12 (step 18
1) Return to the standby state. As a result, when the help mode is set, the memory key 40f is given the same weight as the table raising switch of the first input unit 22.

If the result of determination in step 180 is that the help mode has not been set, the control circuit 30 determines whether or not the back mode has been set (step 1
822). As a result of this determination, if the back mode is set, the control circuit 30 determines that the memory key 40f has been pressed down, and outputs the control signal for raising the back mat, assuming that the back mat raising command has been input. (Step 18
3) Return to the standby state. As a result, when the back mode is set, the update mode key 40e functions as a back mat raising switch.

As a result of the determination in step 122, if the back mode is not set, the control circuit 30 determines whether or not the key lock is released (step 18).
4). As a result of this determination, the control circuit 30 returns to the standby state if the key lock is not released, but if the key lock is released, the control circuit 30 determines whether or not the update mode is set. (Step 185).

If the result of determination in step 185 is that the update mode has not been set, the information that should be read when the start switch of the first input unit 22 is depressed by the control circuit 30 corresponds to that memory key 44f. It is set that the information is in the storage unit (memory-1) (step 186), the light emitting diode 44f corresponding to the memory key 40f is turned on (step 187), and then the operation returns to the standby state.

If the result of determination in step 185 is that the update mode has been set, the control circuit 30 is currently supplying information from the measuring device 26 in the storage section (memory-1) corresponding to the memory key 44f. Update to value (step 188) and cancel update mode (set to non-update mode)
At the same time, the light emitting diode 44e corresponding to the update mode key is turned off (step 189), the light emitting diode 44f corresponding to the memory key 44f is turned on (step 190), and then the standby state is returned to.

As a result, the information in the storage section (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, and the back mat. The angle and the height of the crotch are updated to the current values.

Other memory keys 44g, 44h, 44h,
If either 44i or 44j is rolled down, in steps 181, 183 shown in FIG. 11, the weighting corresponding to the memory key is processed, and step 1
The control circuit 30 executes steps 180 to 190 above, except that the storage section and the light emitting diode corresponding to the memory key are processed at 86 to 190.

Therefore, in the examination mode, the doctor presses the release key 40c after placing the patient in the optimal supine state and the optimal examination state by using the optional foot switch of the first input unit 22, and then the update key 40e. After pressing down, by pressing down any one of the memory keys 40f to 40j, it is possible to set an optimal posture for itself.

The update mode key 40e is used as a means for outputting a command to update the information in the storage unit, instead of setting the update mode in which the information in the storage unit is allowed 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.

The rotation angle of the examination table about the vertical axis is determined by the examination apparatus and its installation location.
Even if the doctor who uses the examination device is different, it is always the same, so that the rotation angle of the examination table is always the same,
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.

Furthermore, the weight of the command key of the second input unit may be changed to only one of the first weight and the third weight.
