摘要： An optical device which makes it possible to reduce time for extending lens units while avoiding collision between lens units during a lens units-extending operation. A first-group barrel is driven by a DC motor. A second-group barrel provided rearward of the first-group barrel on the optical axis is driven by a stepping motor. Photointerrupters detect an intermediate position of the first-group barrel between its retracted position and its shooting position located forward of the retracted position. A control unit controls the DC motor and the stepping motor such that extension of the first-group barrel forward from the retracted position is started, and after the intermediate position is detected by the photointerrupters, extension of the second-group barrel is started.

摘要： A linkage mechanism between a zoom strobe device and a zoom finder device, which contributes to reduced size of a camera, and can control the illumination range of the zoom strobe device and the magnification of a finder optical system of the zoom finder device. A cam plate is disposed linearly movably in a direction orthogonal to an optical axis of a zoom lens barrel unit. The linear motion of the cam plate changes the magnification of the zoom finder optical system and the range of illumination with strobe light. A linkage member is disposed movable along the optical axis. The linkage member has an engaging portion for being engaged with a cam groove formed in the outer periphery of a drive ring, and moves along the optical axis as the engaging portion moves following the cam groove along with rotation of the drive ring, thereby causing the cam plate to move linearly along the optical axis.

摘要： A retractable lens barrel that improves shock resistance without obstructing miniaturization. In the retractable lens barrel, pins formed in the lens barrel are engaged with grooves formed in a cam ring, and the lens barrel is caused to move in a direction of an optical axis by rotation of the cam ring. The pins include a cam pin for moving the lens barrel, and a slip-off preventive pin for preventing the cam pin from slipping off the groove. The grooves include a cam groove with which the cam pin is engaged, and a slip-off preventive groove with which the slip-off preventive pin is engaged. In an area close to a retracted position of the lens barrel, the cam groove and the slip-off preventive groove overlap to be shared grooves with which the cam pin and the slip-off preventive pin are engaged.
