BUTTON SUPPLY DEVICE

PURPOSE:To execute an intermittent rotation of a first rotary plate with high accuracy without using an expensive servomotor, etc., as a driving source by converting a rotation of a driving shaft by the driving source into an intermittent rotation of a driven wheel by an intermittent rotation mechanism for using a dividing means. CONSTITUTION:When an operating plate 72 rotates by 90 deg. from an initial state, a projecting arc surface part 72c1 of the operating plate 72 comes out of a recessed arc surface 65Bl of a driven wheel 65b, and the driven wheel 65b becomes a rotatable state. The driven wheel 65b repeats a rotation and a stop, whenever the operating plate 72 rotates by 90 deg., and a second rotary plate 21 is also subjected to intermittent rotation together by an engagement of a gear part 65a and a gear part 2lb. In this intermittent rotational operation, the driven wheel 65b is fed surely by 90 deg. by the pressing operation of rollers 72d1, 72c12, and also, detained surely by the projecting arc surface parts 72c1., 72c2 at the time of stop, therefore, its intermittent rotational operation is executed very exactly, and a notch part 66a of a first rotary plate 66 stops surely at a feed-out port 13c of a button supply part 13 and a terminal part of a horizontal arc-like path.
