JPS6442054A - Operation switching mechanism - Google Patents

Abstract

PURPOSE:To execute various switching of operation by constituting the titled mechanism so that, when a driving means is operated, either a first member or a second member whose lock member is engaged with a transition part moves integrally with a third member relatively to the other. CONSTITUTION:When a motor 5 rotates, since a lock pin 40 is engaged with the transition part 1a of a first guide part and the straight line part 2a of a second guide part, only the second member 2 moves to the left. When the succession part 2b of a second guide part reaches the position of the lock pin 40, by raising the lock pin 40 along the inclination of the part 1a of the first guide to be moved to the straight line part 1b, the pin 40 is released from the first member 1, at the same time, a third member 3 is engaged by a second member 2, and the members 3, 2 move integrally to the left. And, then the lock pin 40 reaches the position of the transition part 1c of the first guide part, the pin 40 ascends and moves further to the straight line part 2c of the second guide part, so that the third member 3 again is engaged by the first member 1 to make only the second member 2 move to the left.
