    摘要： A mode change-over device for a mode change-over device for a pre-winding type camera in which, after a loading of a film patrone in the camera and before the shooting, a pre-winding of the film is conducted to fully pre-wind the film on a spool and, when the pre-winding is finished, a mode retaining member is unlocked so as to release a mode change-over member thereby operating a mode change-over switch for a shooting mode, such as to allow an unwinding of the film in a frame-by-frame fashion for each shooting exposure, while the mode change-over member is charged by an opening of a back lid of the camera, the mode change-over device comprising; a counter adapted to operate in response to winding and rewinding of the camera; a retaining member for locking the mode retaining member when the back lid has been opened erroneously or accidentally; and a counter engaging member which prevents the retaining member from locking the mode change-over member when the counter is in the initial position, whereas, when the counter is in the counting position, operates the retaining member for making the retaining member lock the mode change-over member.

    摘要： A pre-winding type photographic camera is provided with a mode changing mechanism for changing its operational mode between a pre-winding mode in which film is drawn out from a film magazine loaded in the camera and is taken up around the spool of the camera prior to photographing, and photographing mode in which the film is rewound into the film magazine by one frame each time the film is exposed. The mode changing mechanism is arranged to set the operational mode to the pre-winding mode by, in response to the opening of the backlid of the camera, bringing a mode changing member to a pre-winding mode position, and at the same time causing a force to be charged for bringing the mode changing member to a photographing mode position, and by retaining the mode changing member in the pre-winding mode position in response to the opening of the backlid of the camera, and is arranged to change the operational mode to the photographing mode by releasing the mode changing member in response to completion of the pre-winding mode operation, thereby permitting the mode changing member to move to the photographing mode position under the charged force. The mode changing mechanism is further provided with a magazine switch which is closed in response either to insertion or removal of the magazine and is kept closed until it is opened in response to the opening of the backlid of the camera. The magazine switch is inserted into the energizing circuit of the driving motor for driving the film in the pre-winding mode operation in series with the driving motor.

    摘要： A variable focal length camera having at least one auxiliary lens system which is inserted into or withdrawn from the optical axis of a main lens system. A lens holder holding the auxiliary lens system is swingably mounted on a shaft extending in the direction of the optical axis, and moves forward and rearward along the shaft for focus adjustment. In order to cancel the component of a force in the direction of the optical axis exerted by a tool by which a focus adjusting device is operated, the shaft is arranged to be motionless in the direction of the optical axis. According to a preferred embodiment, on the intermediate portion of the shaft, there is formed a thread meshing with a base portion of the lens holder so that the position of the lens holder is adjusted through rotation of the shaft, and after this lens position adjustment the base portion is fixed to the shaft.

    摘要： In a logarithmic amplifier employing a log-diode connected across an operational amplifier, a dividing resistor and a transistor circuit are connected in parallel between the output of the operational amplifier and the log-diode. The temperature characteristic of the log-diode and that of the transistor circuit cancel each other to effect temperature compensation in the output of the operational amplifier.
