PURPOSE:To switch the state to the automatic stop state immediately in an optional manual stop position, by turning a cam forming member, which interlocks with a stop indication ring, by the operation of a selecting member to disengage a cam inverted member and a stop blade driving shaft from each other. CONSTITUTION:A cam forming member 23 is kept in a constant position for a stop set ring 16 through a pin 20 and a spring 26; and when a stop indication ring is turned to rotate the ring 16, a cam inverted member 28 where a slide pin 29 pressed to a cam face 25 is stood is turned around the pin hole provided in the lower end in the direction of an arrow C. A contact face 30 of the inverted member 28 is pressed to a pin 15 stood on a disc 14 fixed to a driving shaft of a servo motor, and the pin 15 is turned in the direction of an arrow D to turn a blade ring. Next, when a selecting member 33 is pressed downward, the cam inverted member 28 is turned left together with the cam forming member 23, and the pin contact face 30 is released from the pin 15, and simultaneously, a swicth SW-A is closed, and thus, the state is switched to the automatic stop state immediately in an optional stop position. |
