ようになり、開閉部材9はバネ9bの付勢により徐々に反
時計方向に回動して行き、第一の腕に植立されたピン9c
に連結されている羽根を開放させる。When the forward running member 6 slides further to the right, the opening / closing member 9 that was in contact with the surface a of the cam-shaped protrusion 7d of the swing member 7 is moved to the surface b of the cam-shaped protrusion 7d. Then, the opening / closing member 9 is gradually rotated counterclockwise by the urging force of the spring 9b, and the pin 9c set on the first arm 9c.
Open the blade connected to.
その後、公知の露出制御回路によって電磁石装置2が
通電が断たれて減勢されるので、鉄片レバー5が初期位
置方向(反時計方向)へ回動する。After that, the electromagnet device 2 is de-energized and deenergized by the known exposure control circuit, so that the iron piece lever 5 rotates in the initial position direction (counterclockwise direction).
これによって係止腕5aによる閉鎖部材10の係止が解か

Since the opening / closing member is not restricted to the moving area of the forward running member by being connected with the moving member, the position of the delay device is restricted to the moving area of the forward running member by the rocking member having the gear portion. The movement locus of the opening / closing member is small, and the slant is kept small compared to sliding / following a long running member that slides at high speed, and the locking lever is released due to an external impact. Even if the running member has run, the closing member prevents the opening / closing member from trying to operate unless the electromagnet device is excited, so that various effects are obtained in that the blade is not accidentally opened. it can.
