    摘要： A camera includes a plurality of camera operation mechanisms, a sun gear which rotates by means of a motor, a planetary gear which revolves around the sun gear, a plurality of output gears each capable of meshing with the planetary gear by means of a revolution of the planetary gear. The plurality of output gears transmit power to the plurality of camera operation mechanisms, respectively. A holding member switchable from a first state in which the planetary gear is allowed to revolve freely to a second state in which the planetary gear is held at a revolution position where the planetary gear is in mesh with one of the plurality of output gears. The holding member includes a moving member rotatable in interlocked relation to the revolution of the planetary gear. The holding member switches from the first state to the second state by means of a movement of the moving member in a direction different from a direction of rotation of the moving member. A controller determines whether a direction of rotation of said planetary gear when revolution of said planetary gear is to be started for selection of one of said plurality of output gears is identical to a direction of rotation of said planetary gear for rotating said one of said plurality of output gears, and, if both directions differ, switches said holding means to said second state after changing the direction of rotation of said planetary gear into an opposite direction.

    摘要翻译： 相机包括多个照相机操作机构，通过马达旋转的太阳齿轮，围绕太阳齿轮旋转的行星齿轮，多个输出齿轮，每个输出齿轮能够通过转动与行星齿轮啮合 行星齿轮。 多个输出齿轮分别向多个相机操作机构发送动力。 保持构件，其能够从所述行星齿轮自由旋转到所述行星齿轮保持在所述行星齿轮与所述多个输出齿轮中的一个啮合的转动位置的第二状态的第一状态切换。 保持构件包括可与行星齿轮的旋转联动地旋转的移动构件。 保持构件通过移动构件沿与移动构件的旋转方向不同的方向的移动而从第一状态切换到第二状态。 一个控制器确定当所述行星齿轮转动时是否开始用于选择所述多个输出齿轮中的一个的所述行星齿轮的旋转方向是否与所述行星齿轮的旋转方向相同，所述旋转方向用于旋转所述多个输出齿轮 的输出齿轮，并且如果两个方向不同，则在将所述行星齿轮的旋转方向改变为相反方向之后，将所述保持装置切换到所述第二状态。
