Claims

[Scope of utility model registration request]

Three-point positioning that allows a latched member that reciprocates a predetermined distance in a predetermined direction to be selectively positioned at either end position or midpoint position of the reciprocating distance and self-return to the midpoint position. In the mechanism, a pair of launch dowel pins are provided on the latched member at intervals in a direction substantially perpendicular to the reciprocating direction, and the latched member is positioned at a midpoint position of the reciprocating motion. is located substantially perpendicular to the reciprocating motion when the dowel pins are located at the dowel pins, and is provided so as to be swingable around the midpoint position of the line segment connecting the pair of dowel pins. a latch lever formed with sliding edges that abut each other from opposite sides and swings in a predetermined swinging force direction when the latched member moves in either direction of reciprocating motion; and each of the sliding edges. a pair of U's that are connected to each other and are formed to prevent the return movement of the latch lever at an end swing position of the latch lever when the latched member reaches one or the other end position of the reciprocating movement; an electromagnet that attracts a magnetic piece provided on the latch lever and releasably holds the latch lever at the end swing position when the latch lever reaches the end swing position; a return spring that biases the latch lever in a direction opposite to the predetermined one-directional swinging direction; A three-point positioning midpoint position self-return mechanism consisting of a stopper that locks in position.
