摘要： Disclosed is a camera provided with a strobe system. The strobe system includes a capacitor to be charged. Charging voltage of the capacitor can be detected through an output terminal. The output terminal can be electrically connected and disconnected to and from the capacitor by a switching element. The circuit has an input terminal which receives a control signal. In response to the control signal, charging operation is enabled, and at the same time, the switching element is controlled to connect the output terminal to the capacitor. While, if the charging voltage has reached an upper limit, the charging operation is disabled and the output terminal is disconnected from the capacitor for a predetermined period of time by changing the status of the control signal.

摘要： A camera with lens barrier apparatus in which the lens barrier apparatus is driven by a motor that is also used to drive another mechanical element in the camera. The motor is switched between the lens barrier apparatus and the mechanical element by the movement of a lens barrel. In this arrangement, the driving of the lens barrier apparatus and the mechanical element are controlled in accordance with the output of a single sensor, for example an encoder.The driving of the lens barrier apparatus is controlled such that the barrier will not close unless the lens barrel is at the housed position and such that if the lens barrier does not open, the lens barrel will not move. The driving is further controlled such that if the lens barrier apparatus does not move to its intended state, the drive is reversed prior to again attempting to drive to the intended state.The lens barrier apparatus is mechanically arranged such that barrier blades are nonresiliently driven during a portion of the closing or opening operation and are resiliently driven during the remainder of the closing or opening operation.
