It is an object of the present invention to provide an improved disc changer adapted to exactly detect whether a magazine storing a plurality of discs has been attached in the disc changer. When a magazine storing a plurality of discs is inserted into the disc changer, a detection arm and a lock arm both serving as moving members are moved by such an insertion. The lock arm, by virtue of the movement of itself, engages into an insertion groove provided on the backside of the inserted magazine and locks the magazine on the disc changer. The detection arm, by virtue of the movement of itself, actuates a lock detection switch. Here, since the detection arm and the lock arm are both urged by an urging spring, it becomes possible to exactly detect the attachment of the magazine by allowing the moving members locking the magazine on the disc changer to actuate the lock detection switch.

A combination gear having a gear slipping-off preventing structure with an easier combining operation is provided, which includes: a first gear having a shaft hole; a second gear, having a shaft hole, to coaxially couple with the first gear so as to constitute the combination gear; and a shaft to be inserted into the shaft holes of the respective first and second gears, wherein either one of the first and second gears is provided with a coupling male-portion having a securing projection and the other of the first and second gears is provided with a coupling female-portion having a securing recess so that the first and second gears combine together by coupling the coupling male-portion with the coupling female-portion with an engagement between the securing projection and the securing recess. And, a relief portion to permit a relief of an end portion of the securing projection on coupling the coupling male-portion with the coupling female-portion is also provided inside the securing recess.

A feeding screw is rotatably mounted on a chassis of a recording medium reproducing device. A half nut having a semicircular sectional shape is mounted on an optical pickup carriage. The half nut has at least one thread which comprises a thick central portion to be engaged with the feeding screw and thin both side portions not to be engaged with the feeding screw. The optical pickup carriage is fed by a rotation of the feeding screw, being engaged with the half nut.

A disk changer stably maintains a tray with a selected disk loaded thereon even if a physical impact or vibration is loaded from outside therein while the tray is being drawn out, the disk is being reproduced, or the tray is being retained. The disk changer has a retaining device which retains therein a plurality of trays each for loading a disk thereon at corresponding retaining positions parallel to each other in a horizontal state and also draws each tray out from the retaining position in the substantially horizontal direction, a guide member provided at a position corresponding to the retaining position, a tray moving mechanism engaging with a tray selected from the plurality of trays, causing the selected tray to engage with the guide member, and drawing out the selected tray partially or entirely from the retaining device in the substantially horizontal direction to move the tray to a position corresponding to the selected tray, a driving device which drives a disk on the selected tray drawn out to the drawing-out position, having a tray loading section for loading thereon the selected tray, and the guide member engages with the selected tray when the selected tray is drawn out by the tray moving mechanism, and elastically maintains the selected tray on a plane substantially identical to that of the corresponding retaining position collaborating with the retaining device and/or the tray loading section.

A casing of a device has a pair of vertical side walls, and a plurality of vertically arranged optical discs. Each side wall has a vertical guide slit. A disc player has two pins projected from opposite sides. Elevation plates are horizontally slidably mounted on the vertical side walls at outsides thereof. Each of the elevation plates has a V-shaped guide slit comprising an upper diagonal slit and a lower diagonal slit. Each pin is slidably engaged with vertical guide slit and with the V-shaped guide slit so that disc player is held at a vertical position. The elevation plates are driven in a horizontal direction which is changed to an opposite direction at a joint between the upper diagonal slit and the lower diagonal slit. Thus, each of the pins is moved along the vertical guide slit and the V-shaped guide slit, so that the disc player is carried to a position corresponding an optical disc.

A tray loading device has a fixed gear, a first gear coaxial with the fixed gear, and a first arm integral with the first gear. A second gear is rotatably mounted on the first arm and engaged with the fixed gear so as to revolve around the fixed gear. A third gear is rotatably mounted on the first arm and engaged with the second gear. A second arm is secured to the third gear. The second arm has a tray guide provided at an end portion thereof so as to be engaged with one of trays in a magazine. The tray guide is moved along a guide as the first and second arms rotate so as to draw the tray from the magazine.

A disc reproducing apparatus is disclosed in which a disc is delivered from a disc inserting opening to a predetermined position within a player, a clamper arm that extends over a turntable for clamping the disc is operated to fix the disc on the turntable, and then the turntable is rotated to reproduce information recorded in the disc. A disc guide plate is pivotally mounted to the clamper arm such that the disc guide plate engages and disengages the clamper arm. A disc guiding recess into which a small-diameter disc can be fitted is provided to the disc guide plate. When the small-diameter disc is delivered, the small-diameter disc is fitted into the disc guiding recess to be aligned with a clamp position, and when a large-diameter disc is delivered, the large-diameter disc pushes the disc guide plate away to be aligned with the clamp position on the turntable.
