Claims

[Claims for Utility Model Registration] A release operating member having a cover 2d with a slope 2C, which is operated against its own operating habit by a release operation, and placed in the starting position of an electromagnetic release circuit; A locking cam 8a formed of a slope, another push-up surface 8b,
A timer lever, which has a return cam 8d1 and a side surface 8d, is operated against its own operating habits by a self-timer set operation, and switches the electromagnetic release circuit to the self-timer mode; The power supply holding device has a barb 6a that engages with the barb 2d of the operating member, and a barb 6b that engages the locking cam 8a to the side surface 8d of the timer lever, and engages the barb 6b to the return cam 8C by its own operating habit. The timer lever is actuated by the setting operation to move the engagement portion with the locking cam 8a from the return cam 8C through the side surface 8d to the locking cam 8a, and the power supply holding member
b is engaged with the locking cam 8a to hold the timer lever in the set position, and this engagement operation causes the other lock 6a to come into the operating locus of the lock 2d of the release operation member, and the release operation member is When activated by the release operation, the power supply retaining member holder 6a is pushed up against the springiness of its spring material by its own holder 2d and engaged, thereby locking the return operation, and the timer lever is moved in the opposite direction to the setting operation direction. The locking cam 8 is first activated by manual operation in the direction
A pushes up the power supply retaining member ridge 6b on its slope against the springiness of the spring material to release the retainer, and (continued) (by the operation of the timer lever, the push-up surface 8b supports the spring ridge 6b and returns) The electromagnetic device is configured by rotating the power supply holding member with the cam 8C to remove the other lock 6a from the lock 2d of the release operation member or its operating locus, and pushing out the lock 6b from the push-up surface 8b to restore its original shape due to its spring properties. A self-timer for a camera shutter with a release device.
