The body pressure measuring sensor 7 is configured to be able to convert the pressing force generated on the surface of the head 5 into an electric signal such as an electric resistance or an electric capacity in order to measure the pressure by the patient's head. The body pressure measuring sensor 7 corresponds to the pressure sensor of the present invention.

FIG. 2 is a circuit block diagram applicable to the dental treatment chair of FIG. The signal obtained by the body pressure measurement sensor 7 is output to the pressure control unit 9 and is used as a measurement result of the body pressure measurement sensor 7 after appropriate arithmetic processing such as an average value and a maximum value is performed. The measurement result of the body pressure measurement sensor 7 is stored in the storage unit 10.
Further, for example, a signal from the operation panel 8 installed on the work table is also output to the pressure control unit 9. For example, when the automatic adjustment mode is selected on the operation panel 8, the pressure controller 9 automatically controls the internal pressure of the bags 3a and 4a. As described above, if the automatic adjustment mode is provided, the posture of the patient can be easily changed even in a clinic that normally does not adjust the position of the Antodai.

The pressure control unit 9 opens and closes the air supply valve 11 and the exhaust valve 12 based on the measurement result of the body pressure measurement sensor 7.
