    • In an imaging apparatus, an erroneous shake correction is prevented from being performed due to a front curtain shock. A shutter selecting section determines a current state is a shake-correction execution mode when a shake correction switch is ON, when a tripod detection sensor tripod is not mounted, when a shake detection sensor senses a shake amount equal to or larger than a predetermined value, and when a shutter speed is lower than a predetermined value. In this case, the shutter selecting section selects an electronic focal plane shutter as the front curtain, and supplies an operation command signal to an electronic focal plane shutter control section. In other cases, the shutter selecting section determines the current state is not the shake-correction execution mode, and selects a mechanical focal plane shutter as the front curtain and supplies an operation command signal to a shutter drive control section.
    • 在成像装置中,由于前帘震动而防止执行错误的抖动校正。 当抖动校正开关为ON时,当没有安装三脚架检测传感器三脚架时,当抖动检测传感器感测到等于或大于预定值的抖动量时,快门选择部分确定当前状态是抖动校正执行模式 并且当快门速度低于预定值时。 在这种情况下,快门选择部选择电子焦平面快门作为前幕,并且向电子焦平面快门控制部提供操作命令信号。 在其他情况下,快门选择部确定当前状态不是抖动校正执行模式,并且选择机械焦平面快门作为前帘,并将操作命令信号提供给快门驱动控制部。

    • 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.
