摘要： A film wind-up and rewinding motor is connected in series with a resistor so that a voltage commensurate with the motor current appears across the resistor. A level shift circuit shifts the voltage by a given level to generate a voltage signal for switching operation of a transistor. A voltage detecting circuit having a transistor or a bipolar transistor type voltage comparator detects the level of the voltage signal and generates a signal to energize an electromagnet for opening a power switch of the motor when the motor current varies due to forced rotational stopping of the motor or decreased load rotation of the motor causing the voltage signal to rise or drop to a given level.

摘要： A camera has at least one motor, a spindle gear (i.e. a gear having a spindle) for rewinding and thrusting a film, a cam that rotates together with the spindle gear when the spindle gear is rotated in a film-rewinding direction and that remains at rest when the spindle gear is rotated in a film-thrusting direction, a direction-limiting mechanism for permitting the spindle gear to rotate in the film-rewinding direction only when the motor is rotating in a forward direction, and a transmission mechanism that comes into contact with the cam when the motor is rotating in a reverse direction and that, when the cam is in one of predetermined rotation positions, engages with and thereby transmits a driving force of the motor to a corresponding one of driven members provided one for each of the predetermined rotation positions. In this camera, paths for transmitting the driving force of the motor are switched by first rotating the spindle gear in the film-rewinding direction to bring the cam into one of the predetermined rotation positions and then reversing a rotation direction of the motor.

摘要： An electronic instrument, such as a camera, which is supplied with electric power from a battery and selectively receives two kinds of batteries which are different from each other in shape and output voltage. A battery chamber of the electronic instrument is constructed to commonly receive the first and second batteries such that a space of the battery chamber is commonly occupied by parts of the first and second batteries. Additionally, a member is projected into the battery chamber and determines which kind of batteries is received. In response to the result of the determination, a voltage converting means converts the output voltage of the battery to a given voltage such that an electionic circuit of the electronic instrument operates with the optimum voltage condition with the voltage supplied from either one of the batteries which are different from each other in shape and output voltage.

摘要： A motor driven film wind-up and rewind device for cameras is automatically switched from a film wind-up mode to a film rewind mode when the entire length of an unexposed film has been wound on a film take-up spool and surely remains in the film rewind mode thereafter. For the automatic switching of the modes a circuit detects increase in a motor current which occurs with a motor forced to stop after completion of the film wind-up. A movable member which is in the form of an through axle extending through a film rewinding sprocket moves from a first position to a second position immediately after initiation of the motor rotation for the film rewind, switching a switch to a state maintaining the device in the film rewind mode as well as connecting the sprocket with the motor. The movable member is returned to the first position in response to insertion of a film cartridge into a cartridge chamber of the camera and restrained at the first position till the initiation of the film rewind. With no cartridge inserted in the cartridge chamber the movable member is not returned to the first position so that the device remains in the film rewind mode allowing a camera exposure operation.
