摘要： A double-shielding type focal-plane shutter has a closing blade and an opening blade for closing and opening a shutter opening to perform an exposure operation. A closing lever and an opening lever drive the closing blade and the opening blade, respectively. The closing lever has a first closing lever and a second closing lever supported coaxial with each other for undergoing pivotal movement. The second closing lever has a drive portion at a first end thereof for driving the closing blade and an engagement portion at a second end thereof. A lock lever restricts movement of the closing lever. The lock lever has a first mating engagement portion for engaging the engagement portion of the second closing lever in the predetermined position of the closing lever, and a second mating engagement portion for engaging the engagement portion of the second closing lever short of the predetermined position thereof. A set lever undergoes movement to a set position to set the closing lever, the opening lever and the lock lever to predetermined positions.

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.

摘要： A rocking motor comprises a coil wound around a hollow coil bobbin. A rotor is rotatably mounted at a position close to an end portion of the coil bobbin. The rotor has a center shaft and a permanent magnet and is magnetized with two poles such that the positions of the poles are located close to the coil and the magnetization angle is greater than 90 degrees but less than 180 degrees. The positions of the poles of the rotor and the coil are adjacent to one another so that a rotary torque can be efficiently obtained by a magnetic force generated by the coil. The rocking motor can generate a high power output with a relatively low power supply and its operational performance is not adversely affected by an external magnetic field.

摘要： When a driving member is rotated counterclockwise by a single motor with a pair of sectors biased in the closing direction by a biasing spring, a first driving pin causes an operating lever to rotate clockwise. The pair of sectors pivot in opposite directions to each other in association with the driving lever to reach a first position where the sectors are fully open without overlapping the lens opening. When the driving member is rotated clockwise, a second driving pin also causes the operating lever to rotate clockwise. The pair of sectors pivot in opposite directions to each other to reach a second position, that is, a half-open position where an opening smaller than the lens opening is obtained. At this time, The second driving pin abuts on a part of one sector to restrain the displacement of the driving member. Accordingly, the driving member is prevented from overrunning, and no hunting occurs.
