Abstract

PURPOSE:To improve the response of reciprocating motion and to make small the size of an angle detecting mechanism, by applying a given value when the angle difference between a set rotational angle and the direction of a rotatable body during rotation is a given value or more and the angle difference itself when less than a given value, to a driving mechanism. CONSTITUTION:The device consists of a signal generator 11 of a set angle, driving mechanism 14 of a launcher 15, angle detector 16 of the launcher and conversion section 13. The difference between a set rotation angle and the angle of a rotatable body during rotation is calculated at a subtractor 12, and if the difference is at >=+157 deg., it is taken as +175 deg. and transmitted from the conversion section 13 to the driving mechanism 14, and the angle difference from <=+175 deg. is transmitted as it is. Similarly, if the angle difference is >=-180 deg., it is taken as -180 deg., and if <=-180 deg., the angle difference is transmitted as it is. Thus, the rotating and reciprocating movement of the launcher can be made even with the >=180 deg. angle difference or more.
