摘要： 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.

摘要： A camera of this invention incorporates a finder unit capable of changing its magnification corresponding to any one of plural zoom lens barrels (first, second lens barrels) each having different zoom range. When installing the finder unit, first, a positioning pin is inserted into a positioning hole in a rotary frame so as to hold the lens barrel in standard zoom condition. Then, a finder positioning pin is inserted into a cam gear positioning hole and main body positioning hole in finder cam shaft so as to hold a finder lens at a variable magnification position corresponding to the standard zoom condition. With that condition, a zoom driving gear arrangement is meshed with a driving gear portion and cam gear in a rotary frame so that the lens barrel and finder are assembled with each other. This camera realizes reduction of product development term and production cost.

摘要： An epicyclic gear mechanism consisting of a first driven gear, a second driven gear and a rotation regulating member. The first driven gear meshes with a planet gear when the planet gear revolves about a sun gear in one direction and is rotationally driven when the planet gear rotates on its axis in the same position. The second driven gear meshes with the planet gear when the planet gear revolves in the other direction and is rotationally driven when the planet gear rotates on its axis in the same position. The rotation regulating member is actuated by interlocking with the revolving motion of the planet gear. The rotation regulating member regulates the rotation of the second driven gear by engaging with the second driven gear when the planet gear meshes with the first driven gear. The same member regulates the rotation of the first driven gear by engaging with the first driven gear when the planet gear meshes with the second driven gear.
