摘要： To prevent a front end of a slit forming sector of one of an open shutter sector group and a close shutter sector group from colliding with an upper edge portion of a partition opening of a partition plate and preventing leakage of light, a partition plate is provided with a partition plate opening and a projection is formed on the partition plate for preventing sector collision. The projection is formed slightly lower than the level of the upper edge portion of the partition plate opening so that immediately before a slit forming sector of the close shutter sector group comes into contact with the upper edge portion of the partition plate opening, a front end of the slit forming sector rides over the projection and is displaced from the upper edge portion of the partition plate opening. When the slit forming sector is fully closed, a lower face of the front end of the slit forming sector is separated from the projected portion and is brought into close contact with the partition plate by its own elastic force.

摘要： A focal plane shutter for a camera has a synchronous contact member that produces less chattering than conventional synchronous contact members. One end of an opening electromagnet and one end of a closing electromagnet are separately connected to the higher-potential side of a power supply for a CPU in the camera, and the other ends of the electromagnets are grounded. An output circuit has an inverter circuit made up of a transistor and two resistors. A driver voltage for energizing the closing electromagnet is applied to the base of the transistor via a first resistor. The collector of the transistor is connected to the higher-potential side of the power supply via a second resistor. The emitter of the transistor is connected to the lower-potential side of the power supply. First and second voltage signals are produced from an output terminal on the side of the collector. One end of the synchronous contact member is connected to the lower-potential side of the power supply and the other end thereof is connected to the base of the transistor.
