    • A detecting mechanism for detecting a position of a zoom lens used in a camera, in which the same signal is output at each of a plurality of locations through which the lens passes, and in which it is possible to execute a resetting operation of the lens with a lesser mechanical load being exerted upon the lens at both ends of a region within which the lens is driven to move. The mechanism includes a position detection switch that outputs signals of "ON" and "OFF" alternately along a direction in which the lens is driven to move. The switch outputs the signal of "ON" when the lens is on one end of the region, and outputs the signal of "OFF" when the lens is on the other end thereof. When the switch is "ON" at time of the resetting operation, the lens is driven towards the other end thereof, and when the switch is "OFF" at time thereof, the lens is driven towards the one end. This mechanism prevents the lens from striking or hitting on each end of the region.
    • 一种用于检测在相机中使用的变焦透镜的位置的检测机构,其中在透镜通过的多个位置中的每一个处输出相同的信号,并且其中可以执行透镜的复位操作 在透镜被驱动移动的区域的两端处,在透镜上施加较小的机械载荷。 该机构包括沿着透镜被驱动移动的方向交替地输出“ON”和“OFF”的信号的位置检测开关。 当透镜位于该区域的一端时,开关输出“ON”的信号,并且当透镜位于其另一端时输出“OFF”信号。 当在复位操作时开关处于“接通”状态时,透镜朝向其另一端被驱动,并且当开关在其“OFF”时,透镜朝向一端被驱动。 这种机制可防止镜头在该区域的每个端部上撞击或撞击。

    • A device, having a planetary gear and a single motor, in use for switching and transmitting a driving force of the motor to any one of station gears and for driving each station gear in both rotational directions. The operation of locking levers for preventing a planetary gear from revolving around a sun gear is controlled by a cam. The cam is actuated by a driving force of the motor. A spring frictionally connecting the cam and an output shaft of a speed reduction system is interposed therebetween, and a magnet is disposed so as to restrict the movement of the cam when the motor rotates. A sun gear is connected with the output shaft of the speed reduction system with a "play" or gap in order that the rotation of the sun gear is reversed behind time corresponding to the play when the rotation of the motor is reversed, thus making it possible to start actuating the cam earlier than the sun gear for making sure that the locking levers are shifted.
    • 一种具有行星齿轮和单个电动机的装置,用于将电动机的驱动力切换和传递到任何一个工位齿轮并用于在两个旋转方向上驱动每个工作站齿轮。 用于防止行星齿轮围绕太阳齿轮旋转的锁定杆的操作由凸轮控制。 凸轮由电动机的驱动力驱动。 摩擦连接减速系统的凸轮和输出轴的弹簧插入其间,并且设置有磁铁,以便当马达旋转时限制凸轮的运动。 太阳齿轮与减速系统的输出轴以“游隙”或间隙连接,以便当马达的旋转反转时,太阳齿轮的转动反转到对应于游隙的时间,从而使得 可能比太阳齿轮更早地启动凸轮,以确保锁定杆移动。

    • A simple and compact opening and closing apparatus for a film cartridge which has a cylindrical body. The apparatus includes an opening section projecting over the body. The opening section has a film opening and a film cover which opens and closes the film opening. The apparatus also includes a chamber which holds the cartridge and has a loading opening for loading the cartridge into the chamber. A cartridge cover opens and closes the loading opening, and there is provided a lock for the film cover. A driver couples the cartridge cover, and a connector connects the lock with the driver so that the film cover is opened when the cartridge cover is closed. The connector is arranged in a concave area which is formed by the surface of the cylindrical body of the cartridge and the opening section projecting over the body.

    • A camera includes a camera body, the camera body including a cartridge compartment, the cartridge compartment having a cover, the cover being movable between an open and a closed position. The camera includes a lock mechanism, the lock mechanism having a locking state in which the cover is prevented from being moved to the open position from the closed position, even if an operation to open the cover is executed, and an unlocking state in which the cover is movable from the closed position to the open position. The camera further includes a drive mechanism which drives a photographing lens, and an actuating mechanism, the actuating mechanism being movable between a first and a second position of the actuating mechanism by the drive mechanism. The actuating member switches the lock mechanism to the locking state when the drive mechanism moves the actuating mechanism to the first position of the actuating mechanism. The lock mechanism is switched to the unlocking state when the drive mechanism moves the actuating mechanism to the second position of the actuating mechanism.
