An optical disc reproduction apparatus includes a main body, a display unit, a two-axis hinge, and a battery pack. The two-axis hinge has a joint member to connect the two-axis hinge to the main body. The main body has not only a hinge mounting-housing portion to attach and house the joint member of the two-axis hinge but also a housing recess to house a battery housing of the battery pack on right and left sides of the hinge mounting-housing portion on a back end. The battery pack has a U-shaped recess in a center. The recess is located in a position corresponding to the hinge mounting-housing portion in the main body and has a width larger than that of the hinge mounting-housing portion in a rightward-leftward direction.

A tray drive mechanism has a simple structure, and yet both an optical disc clamping operation and a tray opening and closing operation can be driven by one feed motor. The tray drive mechanism comprises: a feed gear and a tray drive gear that are rotated by a feed motor; a rack member to mesh with the feed gear so as to be driven in direction to inner circumference of the optical disc; a plate trigger driven by the rack member so as to slide; and a cam slider to slide in linkage with the plate trigger. When the cam slider is slided in linkage with plate trigger so as to be driven in direction by the tray drive gear meshing with a rack, a boss of the cam slider pushes a slope portion of each of cam grooves and provided in a tray, so that the tray slides to cause a rack of the tray to mesh with the tray drive gear. Thus, the tray is opened and closed by the feed motor.

In an optical disc apparatus, a lens holding body provided with an objective lens is mounted on a base body. The base body has a screw hole and is guided by a guide shaft. An adjusting screw screwed into the screw hole has a slidable portion formed by an annular groove portion and slidably fitting with a rail portion on a chassis side. Each screw thread of a male screw of the adjusting screw is divided into two half sections along the peripheral direction thereof in a manner that a screw thread as one side section and a screw thread as the other side section are slightly deviated positionally to each other in the axial line direction. The screw threads are made in contact with the two slanted surfaces of a female screw.

This chucking apparatusis an apparatus for holding a diskwhich has been placed on a turntableof a disk player, and includes a magnet, a chuck disk, a chuck arm, first engaging facesand second engaging faces. The chuck diskis arranged so as to be faced with the turntable, and adapted to hold the magnet. The chuck diskis a disc-like member which has a plurality of clawsformed around the magnetwhich has been held and projecting toward the turntable, and engaging partsprovided at distal end portionsof the plurality of clawsto be engaged with an outer circumference of the magnet. The chuck armholds the chuck diskrotatably. The first and the second engaging facesandrestrict the engaging partsof the clawsfrom deflecting in a direction away from the magnet.

Chucking apparatus of disk player

A disk apparatus has a chucking mechanism including a receiving member and a disk pressing member respectively provided in an upper position and a lower position with respect to a disk tray. One longitudinal end portion of a drive chassis on which the disk pressing member is disposed is attached to a frame via first buffer members. A free end of the drive chassis is joined to a movable member, which is moved up and down as the movable member is guided by a guide hole of a guide plate provided in a position opposed to the free end of the drive chassis, via a second buffer member made of vibration-proof rubber. The movable member is formed of a hollow cylindrical shaft member, and a second buffer member is interposed in a press fitted state between the shaft member and the free end of the drive chassis.

Disk apparatus with chucking mechanism

A disc rotating apparatus includes a turntable for placing thereon a disc such as CD, DVD. The disc is clamped by the turntable and the disc holding frame. The holding frame is formed, at its main body, with an annular groove. The annular groove is circumferentially partitioned by a plurality of partition walls to thereby provide a plurality of accommodating portions. Each of the accommodating portions accommodates therein one or two or more steel balls. Due to rotation of the turntable or disc, each steel ball is displaced within the accommodating portion, thereby correcting for an unbalanced state wherein a center of gravity of the disc is deviated from an axis of a rotary shaft of turntable.
