Abstract: A disk changer for a disk player capable of storing two disks and changing one of the disks while playing the other. The disk changer comprises a frame, a drawer moveable in an longitudinal direction between an eject and a stock position with respect to the frame, two carriages each for carrying a disk, two sliders for attaching the carriages to the drawer in a vertically displaced relationship and for exchanging the positions of the two carriages in the longitudinal direction between a front and a back portion of the drawer, and a disk playing part located in the back portion the frame, including a turntable and a lift mechanism for placing the disk carried by the carriage in the back portion of the drawer onto the turntable for playing. The ejecting movements of the drawer, the position exchanging movements of the sliders, and the lifting movements of the lift mechanism are synchronized and control by a single motor via a cam system.

Abstract: An electronic-part surface mounting apparatus includes an S-Z shaft vertically movable with respect to the mounted surface of a printed circuit board on which mounted parts such as electronic parts are mounted, and rotatable in a plane parallel to the mounted surface; an arm member revolving around the S-Z shaft; a plural number of Z-shafts, supported by the arm member, being vertically movable with respect to the mounted surface; cam unit revolving around the Z-shafts to cause the Z-shafts to individually move in a reciprocating manner; attraction/mounting unit operating such that at a position where the Z-shafts come nearest to the mounted surface, the attraction/mounting unit releases the mounted part from its seizure by the absorption nozzle attached to the lower end of the Z-shaft and mounts the mounted part on the mounted surface.

Abstract: A disk changer includes a plurality of carriages having a disk on each carriage, a tray accommodating the plurality of carriages, the tray being reciprocated between a disk take-out position and a disk accommodating position, a recording and reproducing unit for driving a disk at a disk driving position for recording data thereon and reproducing data therefrom, a disk setting mechanism for displacing the disk when the disk is at a driving position from a disk loading level to a disk non-loading level and vice versa, a carriage lifting mechanism for vertically moving the carriage, which is at the disk accommodating position, between the lowermost level thereof and a level above the lowermost level, and for vertically moving the carriage between the non-loading level and a level above the non-loading level, and a carriage moving mechanism for moving the carriage to a space formed at one of the disk accommodating position and the disk driving position in association with an operation of the carriage lifting mech
