チ３３の反転信号でメカニズムの動作が開始された場合
に正常な動作から逸脱するという問題点を有していた。Problems to be Solved by the Invention However, in the above configuration, the transfer arm 30
Since the contacts of the switch 33 are reversed before the stopper 32 is locked to the stopper 32 via the connecting pin 31, even if the transfer arm 30 returns before the stopper 32 rotates, the reversal signal of the switch 33 will cause the mechanism to close. However, there is a problem in that when the operation starts, the operation deviates from the normal operation.

ッチ６が作動する。3 is a transfer arm, 4 is a stopper, 6 is a switch base, and 6 is a switch. A connecting pin 2 fixed to a movable body (not shown) is inserted into a guide groove 1a formed on the side surface of the chassis 1, and is moved by a transfer arm 3. The transfer arm 3 is rotated counterclockwise from the state shown in FIG. 2, and the connecting bottle 2 is guided by the guide groove 1a and moves, contacts the tip inclined portion 4a of the stopper 4, swings the stopper 4, and at the same time The switch base 6 engaged with the stopper 4 also swings,
The state shown in Figure 3 will be reached. When the transfer arm 3 further swings from the state shown in FIG. 3, the connecting bottle 2 eventually enters the hook-shaped portion 4b at the end of the stopper 4, and the stopper 4 swings clockwise due to the biasing force of the spring, and at the same time, the switch base 6 also swings and the switch base 6 is placed at the tip of the transfer arm 3.
The actuator of the switch 6, which is fixed to the switch 6, comes into contact with the switch 6, and the switch 6 is activated.
この第１の実施例では移送アーム３の係止は連結ピン２
をストッパー４に係合することとしたが。In this first embodiment, the transfer arm 3 is locked by the connecting pin 2.
However, it was decided that the stopper 4 should be engaged with the stopper 4.
移送アーム３に係止突起を設けることにより、ストッパ
ー４の位置に自由度が増え好ましい。Providing a locking protrusion on the transfer arm 3 is preferable because it increases the degree of freedom in the position of the stopper 4.
