摘要： A motor drive unit is provided with a bridge circuit including series connected first and second MOS transistors, series connected third and fourth MOS transistors, a DC motor connected between a junction of the first and second MOS transistors and a junction of the third and fourth MOS transistors, a power supply line connected to the first and third MOS transistors and a ground line connected to the second and fourth MOS transistors. The state of the DC motor is controlled by on/off controlling the MOS transistors of the bridge circuit. The MOS transistors are controlled such that the motor is continuously short-circuited when a power is supplied to the motor drive unit and the motor is not driven.

摘要： A camera system includes a camera body, an interchangeable lens mountable on the camera body and outputting a discrimination signal, and an intermediate barrel mountable between the interchangeable lens and the camera body. The intermediate barrel has memory means storing therein a plurality of information data regarding the optical characteristic, selector means responsive to the discrimination signal to select one of the plurality of information data from among the plurality of information data, and output means for outputting an information signal conforming to the selected one of said plurality of information data to the camera body. The camera body effects a calculation process on the basis of the information signal.

摘要： A film rewind device in a camera in which a rewind coupling is automatically engaged with a cassette shaft in response to rewind operation has a rotatable member having a spiral groove on its peripheral wall portion and said rewind coupling at the end of the shaft thereof, the rotatable member being slidable in axial direction and rotatable by rewind operation, and a meshing member meshing with the spiral groove at the initial stage of the rewind operation to thereby slide the rotatable member in axial direction to cause the coupling to engage the cassette shaft. The mesh engagement between the meshing member and the spiral groove is released in axial direction when the coupling engages the cassette shaft, so that the meshing member comes to support the rotatable member so as to block the return of the rotatable member in axial direction.
