Abstract: The present invention provides a display device that facilitates product inspection and maintenance. A button section is mounted to a back cabinet, and a power-source circuit board is fitted into a circuit-board fitting slit. Furthermore, the power-source circuit board is locked and fixed by a first circuit-board locking claw, and a main circuit board is locked and fixed by a second circuit-board locking claw. A speaker integrally assembled in a speaker holder is locked and fixed by a speaker locking claw, and thereafter a display panel is caused to be held by a display panel standing holding portion in a standing manner. The wire connection work of a display panel, each of the circuit boards, and the like is performed, the display panel is brought down and placed on a display panel placement portion, a front cabinet is mounted, and a leg portion is mounted to a leg-portion mounting portion.

Abstract: The present invention provides a display device capable of simplifying assembling operation and maintenance operation, and also capable of reducing the occurrence of a sink mark on the surface of the casing. All internal components are mounted on a chassis. Actually, a display panel is mounted on the front side of the chassis (on the side where a front cabinet is positioned), and various circuit boards (power supply board, AV board, MPEG board), a speaker and a recording and reproducing unit are mounted on the rear side of the chassis (on the side where a back cabinet is positioned). A stand supporting unit is attached to the bottom side of the chassis and an operation board is attached to the upper surface of the chassis.

Abstract: To achieve a disc device with a disc changer in which number of motors is reduced, and a quiet and stable switching operation, accurate positioning of a sub-tray, smooth clamp and release of a disc are possible, only a first motor for driving a main tray and a second motor for driving the sub-tray are used as driving sources, and a gear switching mechanism is provided, in which driving channels of the first and second motors can be disconnected.

Abstract: Since the gate construction in a disk device having slot-in format is a single layer of felt in which a single article slit is formed, but the disk maintenance force is weak, and variable. The objective is to provide, on the gate 2 of the disk device 3, a 1st elastic felt 6 on which is formed a single article slit 4 and multiple intersecting slits 5, and a 2nd felt 7 which is fixedly adhered to the rear surface of the 1st felt 6, the elasticity of which is weaker than that of the 1st felt 6. A surface sheet 9 on which is formed a disk transmitting aperture 8 may be also fixedly adhered to the front surface of the 1st felt 6. In order to adjust the hardness by weakening the elasticity of the 2nd felt 7, on the 2nd felt 7, a greater number of intersecting slits 5 may be formed than are existence on the 1st felt 6. In addition, multiple cutouts 10 may also be formed on the single article slit 4 of the 2nd felt 7.

Abstract: To achieve a disc device with a disc changer in which number of motors is reduced, and a quiet and stable switching operation, accurate positioning of a sub-tray, smooth damp and release of a disc are possible, only a first motor for driving a main tray and a second motor for driving the sub-tray are used as driving sources, and a gear switching mechanism is provided, in which driving channels of the first and second motors can be disconnected.
