    • A clutch unit according to the present invention includes a driving sleeve fixed to a driving shaft and a driven sleeve fixed to a driven shaft. A coil-like clutch spring is received on the driven sleeve, and a clutch sleeve is received on the driving sleeve. When the driving shaft is rotated normally or reversely, the driving sleeve abuts one of the arm portions of the clutch spring. Consequently, the clutch spring engages the driven sleeve. Torque producing rotation in either direction is transmitted to the driven shaft. The clutch unit also can operate as an overrunning clutch. When the clutch unit is adapted to a film feeding and driving system in a camera, the clutch unit can be positioned to utilize what had been dead spaces in a camera body, thus promoting compact camera design.

    • A driving force transmission mechanism and method according to the present invention transmits the driving force of a single motor selectively to a plurality of driven gears, comprising a sun gear rotated either in a forward or reverse direction by the motor, a planetary gear engaging the sun gear, and a plurality of driven gears arranged along the revolution orbit of the planetary gear. A driven gear with which the planetary gear is desired to engage is selected by rotating the sun gear in one direction. The driving force is transmitted to the selected driven gear via the planetary gear by rotation of the sun gear in the opposite direction. The proper gear is selected by use of a sensor. Using the driving force transmission mechanism, various driving systems can be driven by a single motor without the need for a complex switching mechanism. The transmission mechanism may use more than one planetary gear and may use more than one planetary gear assembly.

    • A strobe device in which a damper device is built has a light-emitting portion main unit containing a flash-emitting tube and other members therein supported by a rotational supporting mechanism having rotational damper functions. The rotational supporting mechanism includes a rotational shaft fixed to the light-emitting portion main unit and a bearing tube fixed to the camera main unit to which the rotational shaft is fit with a slight gap therebetween. Grease is filled and sealed in the gap between the rotational shaft and the bearing, thus configuring the rotational supporting mechanism. When the light-emitting portion main unit rotates toward a pop-up position due to the pressing force of a spring, friction torque of the rotational supporting mechanism acts to suppress the moving speed, and bouncing at the pop-up position is prevented.

    • In order to realize a lens barrel or camera which is light in weight and small in size and which has performance as high as a single-focus lens, a photographing optical system employed in the lens barrel or camera has four lens groups, and at least two diaphragms are arranged at different positions. Despite the simple structure it has, the photographing optical system enables switching among a number of focal lengths. The diaphragms include: a first diaphragm (diaphragm unit A) arranged at a first inter-lens position defined inside the photographing optical system and controlling the amount of light passing through the system; and a second diaphragm (diaphragm unit B) arranged at a second inter-lens position defined inside the system and controlling the amount of light passing through the system.
