チ操作機構。Optical air that inserts an optical fiber into the grip of the handpiece to guide the light from the light source to the head, and sends compressed air from the air pipe to drive the air turbine and input the switch of the light source circuit. In the turbine handpiece, an air introduction hole 14, a first air chamber 15°, and a second air chamber 16 are sequentially provided in the main body casing 13, and a connecting member 17 to the air pipe is attached to the outer end on the side of the air introduction hole 14. A communication path 19a is provided at the eccentric portion between the first air chamber 15 and the second air chamber 16, and a spring 21 is provided at the center.
A fixing member 19 equipped with a check valve 21 that closes the air introduction hole 14 when no load is applied due to the elasticity of the second air chamber 1 is provided.
6 is provided with a piston 22 which is fitted with an annular packing 23 and can slide in an airtight manner on the inner wall 16'.
A switch actuating rod 24 that is supported by the shaft bearing hole 13'' of the side wall 13' of the casing 13 and can be moved in and out is provided protruding outward from the center of the casing 13, and a switch actuating rod 24 is provided on the outer periphery of the switch actuating rod 24 and between the piston 22 and the side wall 13'. A return spring 25 is interposed, and a fine adjustment valve 28 is provided in the longitudinal direction of the thick wall portion of the casing 13 corresponding to the air introduction hole 14 to adjust the opening degree of a tapered hole 26a penetrating the air introduction hole 14. A switch operation mechanism for a light source circuit, characterized in that the tapered hole 26a and the first air chamber 15 are connected through an air backflow hole 27.
