  • Patent number: 7315291
    Abstract: By opening and closing the sub display with respect to the main display D1 via a hinge H mounted on the side portion, a variety of uses, such as to display different information on the two different displays, are easily realized, whereby easily supporting diversification of displayed information expected in the future and improvement of the functions. The sub display can be rotated upside down in addition to the horizontal open/close movement with respect to the main display D1, thereby increasing the possible states of use. When the sub display is rotated upside down by 180°, each button B and the markings marked thereon rotates and inverted as well, the marking is shown in the normal orientation, but not inverted orientation as a consequent, thereby facilitating identification and operation of each button. The state of currently selected/connected source is displayed on one of the main display D1 and the sub display.

  • Patent number: 5321687
    Abstract: A drive arrangement effects movement of a disk conveying portion to a plurality of first positions and to a second position relative to a case and a rotatable turntable. The drive arrangement includes a driving gear, a slide member having a gear portion engaging the driving gear, and a movable slide plate engaged by the slide member, the slide plate having a stepwise cam portion which effects movement of the disk conveying portion between its positions. The disk conveying portion has two rotatable rollers which can engage an edge of a disk in the case when the disk conveying portion is in one of its first positions, and which rotate in order to extract the disk. As the disk conveying portion moves to its second position, the disk supported by the rollers moves to the turntable, and a clamp member is moved from a retracted position to a clamping position to hold the disk against the turntable, after which the rollers are disengaged from the disk.
