    摘要: Provided is a scanning optical system having reduced dimensions. The scanning optical system (10) is provided with a laser light source section (1), lens optical systems (11, 17, 19) which make laser beams parallel to each other, and a scanning section (2) which performs laser beam scanning by changing the tilt of a scanning mirror (3). The laser beams made parallel to each other travel toward the scanning mirror (3) by being reflected by means of a plurality of optical members, and a plane including at least two optical paths intersects the normal line direction of the reflecting surface (3a) of the scanning mirror (3) in the non-driven state.

    摘要: A film winding system of a camera, capable of automatically winding a film roll, comprising, an electric motor driven so as to winding the film roll, a film winding apparatus driven by the motor, a lock mechanism for locking the film winding apparatus, the lock mechanism comprising a film winding controller connected with the film winding apparatus and a lock lever engaging with the film winding controller so as to restrain an operation of the film winding apparatus, a releasing lever for cancelling an engagement of the lock lever to the film winding controller in advance before the film winding apparatus is actuated, and a loosing mechanism driven by the motor for reducing a degree of the engagement between the film winding controller and the lock lever in advance before the releasing lever swings in the cancellation direction of the engagement.The system operates as follows. Since the loosing mechanism is driven so as to reduce the degree of the engagement between the film winding controller and the lock lever in advance before the releasing lever swings in the cancellation direction of the engagement, the releasing lever cancels the engagement of the lock lever to the film winding controller with light dynamic force. Then, the film winding apparatus is actuated, and the film roll is wound.

    摘要: A film winding system of a camera, comprising: an electrical motor, a film winding device, a cocking device. Both devices are driven by the motor, for winding a film roll and for cocking a predetermined mechanism, through a differential gearing by which one of the devices is driven selectively. The system further comprises a counter for counting a frame of the film roll, a lock lever for locking the film winding device every time one frame of the film roll is wound up, a dis-lock device for releasing a locked state of the film winding device, an order generator for ordering initiation of initial loading, and a controller operating in such a way that the dis-lock device operates at completion of a cocking operation of the cocking device at a normal film winding operation, while the dis-lock device operates when the order generator operates, and an operation of the dis-lock device is terminated when the predetermined total number of the frames is counted by the counter, and the motor is continuously driven in operation of the dis-lock device.When the patrone is loaded at a film chamber, the dis-lock device operates and the locked state is released and the motor is driven. Then, the predetermined total number of the frames is wound without any interruption.

    摘要: A film rewinding system, of camera, capable of automatically rewinding a film roll which is wound by film winding apparatus comprising, an electrical motor, a film winding device driven by the motor, a lock mechanism associated with the film winding device, for locking the winding device every time feed of a frame of the film roll is completed, and a dis-lock mechanism having a dis-lock lever for releasing a locked state of the winding device for feeding the film roll, while the dis-lock lever is located at a neutral position during one-frame feeding and a magnet unit for holding the dis-lock lever at the neutral position, the system comprising: a film rewinding device driven by the motor; a switch operating on and off several times during the one-frame feeding, which is associated with the winding device and operates during film travelling; and a controller which controls the film rewinding device and the magnet unit with a predetermined routine.The system operates as follows. A locking operation of the lock mechanism to the film rewinding system does not operate, at least, during a period from initiation of an operation of film rewinding through completion of one-frame rewinding of the film roll, on the occasion of the film rewinding.
