[0005]

As described above, in a recent dental treatment unit, when the memory / auto switch is operated by the foot, when the memory is operated (the chair is in the gargle position in the upright state, The memory / auto switch for the foot operation can be seen with the eyes when the patient is moved from the raised state to the treatment position in the sleeping state. (When moving from the state to the gargle position in the raised state), there is a problem that the memory / auto switch for the foot operation is difficult to see with eyes, and the operation is difficult.

Further, in a recent dental treatment unit, a foot operation plate 12 which can be operated by a foot is provided at a relatively wide area on both sides and behind the base of the treatment chair. , To operate dental treatment instruments. In addition, the foot operation plate 12 functions as a safety switch, and when the instrument is not taken up, the foot operation plate 12 functions to stop the operation of the chair by pressing the same, so as to maintain more safety. (Japanese Utility Model Publication No. 2-12991).

[0007] The present invention has been made in view of such circumstances described above, in particular, the foot operating plate provided in the base portion of the dental treatment chair (safety switch), have the function of the memory / auto switch Therefore, it is an object of the present invention to make it possible to easily operate the memory / auto operation with the foot without having to visually check the position of the switch.

[0008]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides (1) both sides of a base portion of a treatment chair and
Foot that can be operated in a relatively wide area behind
An operation plate is provided, and the foot operation plate is used to
The instrument can be operated and the instrument
When it is not raised, press the foot operation plate.
In the dental treatment unit configured to stop the operation of the chair , when the treatment chair is in the treatment position or the reference position, when the foot operation plate is continuously turned on a plurality of times , the treatment chair is in the treatment position. From the reference position to the treatment position.

[0009]

As a switch for emergency stop of a dental treatment chair, in a dental treatment unit having a safety switch (foot operation plate) on a base portion of the chair, the condition of the operation of the safety switch is added to the chair so that the automatic operation of the chair can be performed. It can be used as a memory operation switch.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As described above, the control of a recent dental treatment unit is performed by a microcomputer, and as operation switches, up and down movement of a chair, lie of a backboard and memory /
Auto and the like are controlled. Memory / auto is a single switch. If the current position of the chair is in the automatic position (the back plate is up), the operation will proceed to the memory operation. If not, the operation will move to the automatic position (reference position). Is controlled. Further, the input of the base safety switch is also input to the microcomputer, and the operation of the chair is prohibited by this input. Since these inputs are made by a program, under certain conditions, the base safety switch can be used as a memory / automatic operation switch. Next, conditions as an example will be described.

FIG. 1 shows the above-described base safety switch (foot switch).
FIG. 7 is a diagram for explaining the conditions for using the control panel as a memory / auto switch. In the state of A: When the base safety switch is turned on while the chair is operating, it is used for emergency stop. In the state of B: Even if you try to operate the chair with the base safety switch on, it will not work. In the state of C: When the chair is not operating, the chair is operated as a memory / auto operation by operating the base safety switch twice. Further, by determining the time interval T between the two times, a restriction is imposed so as not to operate erroneously.

FIGS. 2A and 2B are flowcharts of the dental treatment unit controlled by the microcomputer as described above. FIG. 2A shows a main program, FIG. 2B shows an interrupt program,
As shown in the figure, the microcomputer control of the dental treatment unit usually includes a main program (a) and an interrupt program (b). The main program (a) controls each operation as a subroutine of each block.
In addition, the interrupt program (b) performs the operation state of the timer time, the operation state of each operation switch input, the external communication state, the detection of the chair position, and the like in the form of a flag, and checks the state in the main program (a). Control. According to the present invention, one subroutine of this main program is programmed, and more specifically, the safety switch of the base unit is also used as a memory / auto switch of the chair, and the treatment chair is operated by the foot switch of the safety switch of the base unit. Thereby, it is possible to move to the automatic position or the memory position.

FIG. 3 is a flowchart for explaining the operation of the present invention. When the base safety switch is not turned on, the program performs the operation of step 1. If the base safety switch is turned on, depending on whether the chair is operating or not, if it is operating, go to step 2 and work as a base safety switch, prohibiting the chair from operating. To operate the base safety switch as a memory / auto switch,
When the base safety switch is pressed for the first time, the procedure goes to step 4, where the operation timer is started and the operation flag is set. Next, if the base safety switch is not turned off once, the operation flag cannot be reset.
And Next, when the button is pressed the second time, if the interval between the first time and the second time is during the operation timer time, the procedure goes to step 5 to perform the memory / auto operation of the chair. Note that the operation prohibition of the chair is prohibited by the chair manual switch processing program and the chair memory / automatic processing program. The memory / auto operation is started by a memory / auto processing program of the chair.

[0014]

As is apparent from the above description, according to the present invention, the operator can move the chair to the memory / auto position by foot operation without touching the hand and without having to visually check it. I can do it. In particular, since the operation can be performed without visual confirmation, it is possible to concentrate on the next treatment or the like, so that the flow of the treatment can be smoothly performed.
