(3) When a detection signal from c is input, a priority holding circuit that outputs a priority signal corresponding to the earliest detection signal and holds the output state of the priority signal (12), and the therapeutic device
Switches (13) a, (13) b, (13) provided corresponding to Ba, Bb, Bc, respectively, and permitting the flow of the working medium necessary for the operation of the treatment instrument B corresponding to the input of the priority signal. and the air source (14) in the pressurized air supply circuit (6),
In the water supply circuit (15), the water source (15) is the operating power supply circuit.
A power source (16) is connected to the power supply circuit (8) and the illumination power supply circuit (9), and a suction source (17) composed of a vacuum pump is connected to the suction circuit (10). Reference numeral (18) is an operation switch for outputting the working medium from a working medium supply circuit in which the supply of the working medium is set by controlling the operation medium supply control section (11) by a foot operation, for example.

In use, however, in FIG. 1, for example, when the first treatment instrument Ba is first detached from the hanger and hand-held, the identification signal read by the detection unit (2) a in the state of being hooked on the hanger is detected. It is output from the circuit (3) a and is input to the identification command circuit (4). The identification command circuit (4)
Is a working medium supply control unit (11) and a working medium supply circuit necessary for operating the first treatment instrument Ba (for example, in the case of an air turbine handpiece, an air turbine and a pressurized air supply circuit (6) for spraying mist). , A water supply circuit (7) for spraying fog and a power supply circuit (9) for lighting, and in the case of a micromotor handpiece, an operation power supply circuit for operating a micromotor
(8), pressurized air supply circuit for spraying mist (6) and water supply circuit
(7), and if it is a syringe, mist, water, a pressurized air supply circuit (6) and a water supply circuit (7) for ejecting pressurized air,

(0)) commanding a signal to set the output state, and the detection signal from the detection circuit (3) a accompanying the removal of the first treatment instrument Ba is input to the priority holding circuit (12) and the latch circuit (5), respectively. Accordingly, the latch circuit (5) latches the output state of the identification command circuit (4), and the priority holding circuit (12) naturally gives priority only to the switch (13) a corresponding to the treatment instrument Ba. A signal is output to open the switch (13) a.

When the operation switch (18) is operated from this state by, for example, a foot operation, only the various working medium supply circuits that are in an operable state by the operation signal being given to the working medium supply control section (11) are activated, and the operation thereof is performed. The medium is supplied to the first therapeutic device Ba through the switch (13) a and the flexible hose (1) a,
The therapeutic device Ba is activated. And in this state, the second and third
Since the output state of the latch circuit (5) does not change even if the therapeutic instruments Bb and Bc are held by hand, the output state of the identification command circuit (4) is maintained, and accordingly, the working medium supply control unit (11) The output state of the working medium of is maintained during the operating state of the operation switch (18), and the open wave state of the switch (13) a is also maintained by the priority signal from the priority holding circuit (12). Even in the state, the second and third therapeutic instruments Bb and Bc do not operate.

Further, in this state, when the first treatment device Ba is hooked on the corresponding hanger (in this case, FIGS. 2 and 3 are also hooked on the hanger), the output of the priority holding circuit (12) disappears. Then, all the switches (13) are closed and the identification command circuit (4) and the latch circuit (5) are reset.

FIG. 2 shows another embodiment of the device of the present application, which differs from the above-mentioned embodiment in that the latch signal is generated by operating the identification command circuit (4) by the priority signal from the priority holding circuit (12). According to this configuration, when the treatment instrument B is detached from the holding member, the unique signal of the treatment instrument B is input to the priority holding circuit (12) via the detection circuit (3). ,
Since only the signal preferentially held by the priority holding circuit (12) is input to the identification command circuit (4), the identification command circuit (4) operates the treatment instrument B corresponding to the working medium supply control unit (11). Therefore, the output state of only the working medium supply circuit required for is set.

As described above, according to the present application, the working medium supply circuit necessary for actuation of various treatment instruments is provided in the treatment apparatus main body such as a dental unit, and the treatment apparatus main body is provided with various treatment instruments. Connected via a sex hose, select only the working medium supply circuit necessary for operating the therapeutic instrument based on the unique signal of the therapeutic instrument when holding the arbitrary therapeutic instrument by hand, and under suitable conditions. Since it is configured to operate only the earliest treatment device held by operating the operation switch in this state, even if multiple treatment devices are provided, the configuration inside the treatment device main unit can be achieved by sharing the working medium supply circuit. It has the advantage that it can be simplified, and that it is convenient because only the treatment device that was held first can be used preferentially.
