In an apparatus for reproducing an optical disk (302), supporting means (100) are provided to be moved between a disk insertion opening and a disk storing device (300). A driving roller (101) is rotatably mounted on the supporting means (100) for carrying a disk (302) inserted in the opening toward the disk storing device (300). The supporting means (100) are moved between the opening and the disk storing means (300), and the driving roller (101) is driven for carrying the disk (302) from the opening to the disk storing device (300).

An internal magnetic circuit is formed by a plate (20) forming a pole piece, a vertically magnetized magnet (21) attached to a bottom face of the plate, and a yoke (22) attached to a bottom face of the magnet. A magnetic gap (G 0 ) is formed between the plate and the yoke. The yoke includes a bottom part (22b) attached to the bottom face of the magnet, a side part (22c) standing on the side of the plate, and a folded-back part(22d) folding downwards over the side part to face the magnetic gap. Thus, the internal magnetic circuit having a uniform magnetic flux density inside the magnetic gap along the direction of its length is provided.

A mode control ring (200) having cams for operating various devices in a cassette tape recorder is rotatably mounted on a base plate (160). A normal pinch device (450) and a reverse pinch device (400) are mounted on the base plate. Each of the pinch devices comprises a capstan (600, 650), a pinch roller (420, 470) provided on a swing lever so as to be engaged with the capstan, and an idler (604, 654) provided to be engaged with a reel gear (605, 655). A power transmitting device (601, 612, 651) is provided for transmitting a driving power from a motor (150) to each capstan. The normal pinch device (450), reverse pinch device (400) are disposed along the circumference of the mode control ring (200), and each swing lever (410, 460) is arranged so as to be moved in the radial direction of the mode control ring (200).
摘要:
An EL display panel comprises a plurality of insulating substrates (10) which are aligned side by side. Each substrate has an elongated first side surface (11) and an opposite second side surface (18), a plurality of discrete electrodes (20) formed on the first side surface (11), a common electrode (30) formed on the second side surface (12), and a plurality of luminescent elements (40) formed on a top surface (13) of the substrate (10). The discrete electrodes (20) of the adjacent substrates are electrically connected with each other.
