摘要:
A music box comprises a comb having vibrating teeth, a drum having elements for plucking the comb for playing music, a driving source for rotating the drum, a speed governor for regulating rotation speed and a frame for supporting the comb, drum, driving source and speed governor. The speed governor further comprises an accelerating train having two worms and a control device provided on a last row of the accelerating train. A position maintaining element is integrally arranged with the frame for preventing at least the first worm positioned on the driving source side, of the two worms referred to, from moving in the thrust direction. In one form, the music box has a driving source which includes a spring. One end of the spring is engaged with a winding shaft arranged in a spring housing of the spring and the other end is engaged with an engagement section provided on the frame. A contact section is formed on the frame for preventing the other end of the spring engaged with the engagement section from moving out of the spring housing.

A music box is arranged for increased compactness. The music box includes a comb having vibrating teeth, a drum with a rotational axis with a plurality of pins on an outer surface for engaging ends of said teeth, a coil spring having a winding shaft for driving the drum, an accelerating gear row for accelerating the rotation speed of the spring winding shaft, a braking member engaging with the gear row for braking and a base frame for transmitting the vibration of the comb to a mounting member. The rotational axis of the drum and the spring shaft are arranged vertical to the base frame and the spring shaft is substantially centered on the frame. The drum, comb, accelerating gear and brake are disposed about the centered spring shaft to provide a more compact arrangement.

An optical unit may include a fixed body, a movable module which holds an optical element, a swing support point which swingably supports the movable module, and a shake correction drive mechanism structured to swing the movable module with the swing support point as a swing center. The swing support point may be structured of an abutted portion of two members in an optical axis direction between a bottom part of the movable module and a bottom part of the fixed body. At least one of the two members may be made of elastic material.

An optical head device comprises a frame-type laser photo emitter having a semiconductor laser chip mounted on a lead frame. The frame is molded of resin and opens on a side where the chip is mounted. The frame-type laser photo emitter is mounted onto a base together with optical components. A photo emitter holder is provided for mounting the photo emitter on the base. The photo emitter holder has mounting portions for mounting the laser photo emitter and a notch that is cut out in a direction orthogonal to an optical axis of light emitted by the semiconductor laser chip for mounting the laser photo emitter onto the mounting portions. The laser photo emitter is fixed to the notch by an adhesive.

An optical unit may include a fixed body; a movable module which holds an optical element; and a shake correction drive mechanism which is structured to generate a drive force for swinging the movable module with respect to the fixed body. The shake correction drive mechanism may include a plurality of permanent magnets which are provided on an outer peripheral face of the movable module at positions separated in a circumferential direction around an optical axis of the optical element; and a sheet-shaped coil which is extended in a circumferential direction in the fixed body and is integrally provided with a plurality of coil parts facing the permanent magnets and a terminal part electrically connected with the coil parts.

The purpose of the present invention is to provide an optical unit with camera-shake correction function capable of minimizing the load applied to a movable element from a flexible wiring substrate even when the movable element is oscillated, in order to correct camera shake. In an optical unit provided with a camera-shake correction function, a movable element can be oscillated about an oscillation support point by actuating a drive mechanism for camera-shake correction, and camera shake can therefore be corrected. In a flexible wiring substrate drawn out from the movable element, a folded part folded along the rear end portion of the movable element in the optical axis direction is formed in a drawn-out portion from the movable element, and in the optical axis direction, the oscillation support point is positioned between the surface of the folded part that faces the end part on the other side −Y in the Y-axis direction of the rear end portion of the movable element in the optical axis direction, and the surface that faces toward the rear in the optical axis direction at a fixed part of the flexible wiring substrate with respect to a fixed body.

A shake correction device may include a support body to swingably support a camera module; and a shake correction mechanism to correct the shake by swinging the camera module so as to incline an optical axis of the lens with respect to the support body. The support body may include a case body formed in a substantially tube shape. The shake correction mechanism may include a shake correction coil fixed to an inner peripheral face of the case body; a shake correction magnet disposed on an inner peripheral side of the case body; and a spring member having a support body fixing part which is fixed to the support body, a magnet holding part which holds the shake correction magnet, and a spring part which connects the support body fixing part with the magnet holding part.
