PURPOSE:To select the point direction by holding a pin by means of a pin receive groove disposed on the peripheral edge of an umbrella-type rotor and a stop plate having a notch permitting a point to pass therethrough, and slapping a pin having a point projected over the notch of the stop plate by means of a slapping rod to remove the pin. CONSTITUTION:Pins A scooped up by a fan-like plate 2 are slid into a receive groove 41 disposed on the peripheral surface of an umbrella-type rotor 4. Among the pins 4, the pins having points directed to the back are settled in the groove 41, and the pins having points directed to the front have the points projected over the notch of the stop plate 42. The projecting point is engaged with a notch 52 of a rotary slapping rod 51, so that the pin A is slapped down. Accordingly, only the pins A having points directed to the back are selected to stay therein. |
