FIG. 2 shows a second embodiment of the present application, and this embodiment shows a case in which a plurality of treatment instruments are simultaneously installed in the treatment apparatus main body. That is, D [Da to Dc] is the holding member (25) [(2
5) a to (25) c] and the joint member (26) [(26) a to (26) c] are detachably connected, and the joint member (26) [(26 ) A to (26)
c] is a flexible hose (27) [(27) a to (27) c]
A hand-held treatment instrument such as an air turbine handpiece, a micromotor handpiece, or a dental suction tool, which is connected via the handheld member (25) and the joint member (26). At the time of connection, corresponding members, for example, a hand-held member (25) a for an air turbine handpiece and a joint member (26) for an air turbine handpiece

[(28) a to (28) c] are connected. (29)
[(29) a to (29) c] is a detection unit provided on a holding member such as a hanger mounted on a dental table for holding the treatment instrument D, and the detection unit (29) corresponds to the treatment. With the device D held by the holding member, a signal peculiar to the therapeutic device provided on the therapeutic device D side, for example, a bar code is read, and this signal is detected by the detection circuit (30) [(30) a to (3).
0) c] to the priority holding circuit (39) described later. An identification command circuit (31) that reads information from the detection circuit (30), identifies the information and outputs the identification signal, and a detection signal from the detection circuit (30) in the treatment apparatus main body A; In addition to the latch circuit (32) which holds the output state of the identification signal from the identification command circuit (31) when the corresponding signal corresponding thereto matches, the identification command from the identification command circuit (31) A pressurized air supply circuit (33) for receiving a signal and setting a suitable pressurized air corresponding to the signal,
A water supply circuit (34) which receives the command signal and sets a suitable amount of water corresponding to the signal, and receives the command signal and sets a required electric energy such as a DC high frequency output or an ultrasonic wave output corresponding to the signal. Working power supply circuit (35),
A plurality of working medium supply circuits such as a power supply circuit for lighting (36) that receives the identification signal and sets electric energy for lighting and a suction circuit (37) that receives the identification signal and sets the supply of required negative pressure are provided. A working medium supply control section (38) provided,
The detection signal from the detection circuit (30) when the therapeutic device D is separated from the detection unit (29) is input, and the earliest detection signal among the detection signals is output as a priority signal, and the priority signal is also output. And a priority holding circuit (39) for holding the output state of the device, and an opening / closing circuit provided corresponding to the treatment instrument D, which allows the corresponding treatment instrument D to flow the working medium necessary for its operation when the priority signal is input. Bowl (40) [(40) a,
(40) b, (40) c] and the pressurized air supply circuit (33) has an air source (41) and a water supply circuit (3).
4) has a water source (42), the operating power supply circuit (35) and the lighting power supply circuit (36) have a power source (43), and the suction circuit (37) has a suction source (a vacuum pump). 44) are connected respectively. Reference numeral (45) is an operation switch for controlling the operation medium supply control section (38) by, for example, a hood operation to output only the required operation medium set from the operation medium supply circuit.

However, at the time of use, as shown in FIG. 2, if the hand-held member (25) [(25) a to (25) b corresponding to the joint member (26) [(26) a to (26) c] is connected, , Adapted signals are output from the adapted signal sources (28) [(28) a to (28) c] to the latch circuit (32).

Then, for example, if the first treatment device Da is first removed from the hanger and hand-held, the identification signal read by the detection unit (29) a in the state of being hooked on the hanger is output from the detection circuit (30) a. , This is the identification command circuit (3
1), the discrimination command circuit (31) outputs to the working medium supply control section (38) the output state of the working medium supply circuit necessary for operating the first therapeutic instrument Da, as already described. And a detection signal from the detection circuit (30) a associated with the removal of the first treatment instrument Da is input to the priority holding circuit (39) and the latch circuit (32), respectively, to latch the signal. The circuit (32) outputs a latch signal and latches the output state of the identification command circuit (31) by AND input of the input detection signal and the corresponding adaptive signal, and the priority holding circuit ( 39) outputs a priority signal only to the switch (40) a corresponding to the treatment instrument Da, and the switch (40)
A is opened.

Then, if the operation switch (45) is operated from this state by, for example, a hood operation, only the various working medium supply circuits that are in an operable state by operating signals are given to the working medium supply control unit (38) Switchgear medium (40)
a through the flexible hose (27) a and the first treatment instrument
It is supplied to Da and the therapeutic device Da is activated. In this state, even if the second and third therapeutic instruments Db and Dc are held by hand, the output state of the latch circuit (32) does not change, so that the output state of the identification command circuit (31) is maintained and accordingly the operation is performed. The output state of the working medium from the medium supply control section (38) is held during the operation of the operation switch (45), and the opening state of the switch (40) a is also kept by the priority signal from the priority holding circuit (39). Therefore, the second and third treatment tools Db and Dc are held in this state and are not activated.

When the first treatment device Da is hooked on the corresponding hanger in this state (in this case, the other treatment devices are hooked on the hanger), the output of the priority holding circuit (39) disappears. As a result, the first switch (40) a is closed, and the identification command circuit (31), the latch circuit (32), and the priority holding circuit (39) are reset.

If, for example, another hand-held member that does not correspond to the joint member (26) b is erroneously connected, a matching signal corresponding to the joint member (26) b will not be output to the latch circuit (32). When a hand-held treatment tool formed by connecting a hand-held member to the joint member (26) b is held, a detection signal corresponding to the treatment tool is output to the latch circuit (32). Since it is not input to the latch circuit (32), the latch circuit (32) does not output a latch signal, and thus the output state of each working medium supply circuit from the identification command circuit (31) to the working medium supply control unit (38). No command signal for setting is output, and even if the operation switch (45) is operated in this state, the respective working medium supply circuits do not operate, and the working medium is not supplied to the joint member (26). Therefore, the treatment instrument formed by connecting the wrong hand-held member to the joint member (26) b does not operate.

In FIG. 3, the priority signal obtained from the priority holding circuit (39) is changed to the latch circuit (3) in place of the detection signal input of the detection circuit (30) to the latch circuit (32) in the second embodiment.
The third embodiment in the case of inputting to (2) is shown, and the operation is the same as in the case of the embodiment shown in FIG.

In the second and third embodiments, the case where the input signal to the identification command circuit (31) is output from the detection circuit (30) is shown, but the output from the priority holding circuit (39) is shown. Needless to say, the configuration may be such that the input is input to the identification command circuit (31).

EFFECTS OF THE INVENTION As described above, according to the present application, when a hand-held member having a different rating, for example, that does not correspond to a joint member is erroneously connected, the treatment instrument does not work, so that it can be used safely and can be used in various ways. Since the working medium supply circuit necessary for operating the treatment instrument is installed in the treatment device body such as the dental unit, it is possible to use various treatment instruments of different ratings or types without changing the structure of the treatment device body. Is possible,
Furthermore, according to the present application, when a plurality of various treatment instruments are connected to the treatment apparatus main body and any one treatment instrument is handheld, it is necessary to operate the treatment instrument based on the unique signal of the treatment instrument. The working medium supply circuit is configured to operate only the earliest therapeutic instrument held by operating the operation switch in this state while selecting only the appropriate working medium supply circuit. By sharing the above, the configuration inside the main body of the treatment device can be simplified, and since only the treatment device that was held first can be used preferentially, other treatment devices can be held and used for parts replacement. There are some advantages.
