Abstract: PROBLEM TO BE SOLVED: To simplify a constitution, to facilitate assembling, to increase the resistance against impact from the outside, to miniaturize an entire device, and to move a moved body appropriately.
SOLUTION: The moved body 1 can be moved vertically via a support pin 2 engaged with a guide hole 5 in a side plate 4. When a first cam plate 6 is rotated so that a first support groove 8 engages with the support pin 2 and a second cam plate 7 is moved linearly so that a second support groove 14 does not engage with the support pin 2, the support pin 2 moves along the guide hole 5. When the first cam plate 6 is rotated so that the first support groove 8 does not engage with the support pin 2 and the second cam plate 7 is moved linearly so that the second support groove 14 engages with the support pin 2, the movement of the support pin 2 stops. These operations are cyclically repeated to allow a lifting up operation or a lifting down operation.

Abstract: PROBLEM TO BE SOLVED: To make it difficult to execute wire tapping, and to easily attain reception in a normal device. SOLUTION: A video signal received by a receiving circuit 21 is extracted through a de-scramble circuit 22 to an output terminal 23. A voice signal received by the receiving circuit 21 is supplied through a separating circuit 24 to a de-scramble circuit 25, and extracted to an output terminal 26 after arbitrary bit inversion or the like is restored. Moreover, key signals K4 and K3 from a memory 37 are supplied to random signal generating circuits 41 and 42 as initial values, and a frame synchronizing signal from the separating circuit 24 is detected by a detecting circuit 43, and supplied to generating circuits 41 and 42. Then, generated random signals are selected by a switch 44, and supplied to the de-scramble circuit 25 and a subtracter 27, and a flag (identification signal) indicating the switched state of the switch from the separating circuit 24 is supplied to a switching signal generating circuit 45, and the switching of the switch 44 is controlled according to a signal from the generating circuit 45.

Abstract: PROBLEM TO BE SOLVED: To surely prevent dust from being attached onto an objective lens and further prevent dust from entering an optical block. SOLUTION: A cover plate 45 is provided to cover a transparent aperture 24 of a lid member 21 that covers an objective lens 11 when an optical pickup section 12 is moved to an outer position at which the objective lens 11 is caused to be positioned at the outside of an optical disk mounted onto a disk rotation drive mechanism 3. An operating section 55 for moving the cover plate 45 away from the objective lens 11 is provided either at the lid member 21 or the cover plate 45. When the optical pickup section 12 is moved to the outside of the optical disk, the cover plate 45 is caused to be moved away from the objective lens 11 by means of the operating section 55, thereby causing the cover plate 45 to cover the objective lens 11 while avoiding abutment against the objective lens 11.

Abstract: PROBLEM TO BE SOLVED: To miniaturize an entire loading device for a recording medium by moving a holding means receiving a driving force in a horizontal direction by a first drive transmitting means always receiving a driving force only when the recording medium holding means is moved from the first drive transmitting means. SOLUTION: A driving mechanism is constructed by providing a gear 35 rotated by a drive motor via a transmission belt, a gear 36 meshed with the gear 35 to be rotated, gears 37, 38 and 39 corresponding to disk trays 3, 4 and 5 and a gear 40 meshed with the gear 36 in a drive shaft 41. The driving mechanism is always driven to rotate the drive shaft 41 via the gears 35 and 36. The shaft 41 moves one tray selected by a switching means in a horizontal direction in the inner and outer sides of the device. Since the shaft 41 is supported to be freely rotated in a side wall 42 erected in the inner side of the side face of device with a driving force from the motor disposed in the bottom surface part of the device, a width dimension of the device is reduced to a minimum.

Abstract: PURPOSE:To ensure the delivery of a disk by pressing one section of the circumferential surface of the disk housed in a disk housing part, pushing out a part opposite to this section to hold the disk between disk guides and rotating the disk between a roller and the guides and revolving the disk around the outer circumference of the roller. CONSTITUTION:The disk loader 1 is provided with one pair of disk housing parts 3 and 4 housing a large number of disks 2 under the vertical piled state, disk drives 5 and 6 provided in this vertical direction, i.e., in the state of their upward or downward arrangement and a disk carrier 7 for reciprocating movement between the drive and the housing part. When a loading signal for a prescribed disk is given from the device to a control of the carrier 7 under the above-stated constitution, the carrier 7 is moved, and the disk is received by a delivery device 8. When recording/reproducing is over, the disk is returned to its original position by a returning mechanism 131. That is, the movement like a planetary gear is performed between the roller and the guides.

Abstract: PURPOSE:To smoothly and surely execute the chucking of a disk without any shock by speed-reducing a disk placing plate, rotating a cam means and ascending a disk holding means when a planet gear arrives at an arc-shaped rack part. CONSTITUTION:When a planet gear 33 is rotated while a disk placing plate 4 is pulled out, the placing plate 4 is moved in a housing direction at the linear part of a rack 47. When the gear 33 arrives at the arc-shaped part of the rack 47, the movement is speed-reduced, and by the rotation of a swaying arm 30, a cam member 39 is rotated. Thus, an engaging pin 19 of a base unit 8 ascends along a cam groove and a unit 8 is also turned in the ascending direction. An optical head 12, a turn table 15, etc., protrude on the upper surface of a chassis 2, the disk is pushed up to a table 15 and attracted to a chucking member 54. Thus, the chucking of the disk is executed without any shock, smoothly and surely.
