Filed: 1981-09-22
Abstract: PURPOSE:To feed a feed shaft intermittently at a fixed stroke via balls fitted inside a taper hole by moving a movable member such as a plunger to be magnetically reciprocated or the like. CONSTITUTION:When current of a fixed direction is supplied to a coil 6 and a plunger 12 is moved to the right to be in contact with a stopper 17, a taper hole 14 is moved as leaving the first catching ball 19 behind. Consequently, a feed shaft 16 is prevented from moving in linkage, and spring 22 and 23 are extended to push the ball 19 to the right to be caught by the inner wall of the taper hole 14 as illustrated. At this stage, when the direction of the current supplied into the coil 6 is changed, the plunger 12 is moved to the left at a fixed stroke against 22 and 23 until it is dashed to a stator core, and the feed shaft 16 caught via the ball 19 is moved to the left in linkage. In this construction, as the plunger 12 repeats its reciprocation, the feed shaft 16 is moved to the left intermittently at a fixed amount of movement.
