Abstract: PURPOSE: To obtain a disk table having an accurate shape and large coercive force of a chucking magnet by feeding a resin from a gate disposed on the opposite side to a magnet in respect of a yoke and carrying out insert molding. CONSTITUTION: The body 1 of a table for holding a recording medium disk and rotating it has a fixing body 4 with a recess 5 enclosing a central hole 2 in the upper part. A circular yoke plate 7 and a circular magnet 6 are fixed in the recess 5. The magnet 6 attracts a disk chucking plate and the periphery of the fixing body 4 is fixed in a chucking positioning hole to position chucking. When insert molding is carried out so as to combine the fixing body 4 made of a synthetic resin with the magnet 6 made of a magnetic body and the yoke plate 7, a molten synthetic resin is fed from a gate disposed on the opposite side to the magnet 6 in respect of the yoke plate 7 and the deterioration of the magnetization of the magnet 6 contg. a rare earth metal by the high temp. of the molten synthetic resin is prevented.

Abstract: PROBLEM TO BE SOLVED: To realize a recording medium reproducing device which can additionally improve operability and working efficiency. SOLUTION: The recording medium reproducing device is so controlled that a lifting means adjusts the height positions of the arbitrary, recording medium and a transfer means and that the transfer means transfers the arbitrary recording medium to the outside of the device after the transfer means houses the recording medium to be reproduced into a housing section in the state that the lifting means is held according to a user's instruction while the recording medium is reproduced by a reproducing means, by which the laboriousness of previously storing the place where the transfer means returns the recording medium into the housing section and to retrieve the place for returning the recording medium in the stage of housing may be previously averted.

Abstract: PROBLEM TO BE SOLVED: To realize a recording medium reproducing device which may be additionally improved in operability and working efficiency. SOLUTION: The recording medium reproducing device is constituted in such a manner that a transfer means houses the recording medium inserted from outside the device into a housing section in the state that a positioning means is held and thereafter the positioning means positions the arbitrary recording medium and the transfer means and that the transfer means transfers this arbitrary recording medium to a reproducing means. The laboriousness of previously storing the place where the recording medium is returned into the housing section or retrieving the place where the recording medium is returned in the state of housing may be thereby previously averted.

Abstract: PURPOSE:To improve a space utilization by providing a disk tray and a cassette tray which horizontally move in the same direction with a disk and a cassette for loading and are used for a recording and a reproducing. CONSTITUTION:If a disk tray 3 and a cassette tray 4 are placed at the outside of a front panel 7 and are placed to a position where they move together, they become one on top of the other. Place a cassette 2 on the tray 3 and place a disk (CD) 1 on the tray 4 and by a loading instruction signal, a motor 9 makes a forward revolution and drives a belt transmission mechanism 10, a gear train 11 and others. Thus, the CD 1 and the cassette 2 are loaded to a disk deck 16 and a cassette deck 27, respectively and after these operations, the decks 16 and 27 perform a recording and a reproducing of the CD 1 and the cassette 2. Thus, a CD and a cassette are simultaneously loaded and a recording and a reproducing are performed, a space utilization is improved and the width of the device becomes small.

Abstract: PROBLEM TO BE SOLVED: To realize a disk reproducing device which may be additionally improved in operability, simplified in constitution and downsized. SOLUTION: The disk reproducing device is constituted to transfer one disk selected from plural disks housed in a stocker between a predetermined first height position in the stocker and a reproducing means and to transfer the disk between a predetermined second height position in the stocker and a disk insertion section. In reproducing or inserting or removing of the selected disk, the disk may be thereby supplied to the transfer route of the reproducing means or disk insertion section merely by carrying out the simple lifting motion without moving the stocker to the reproducing means side or disk insertion section side.

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: PURPOSE:To further miniaturize a disk housing device with a simple constitution. CONSTITUTION:An engaging part 42B, 43B, 44B, 45B or 46B is engaged with the engaging projection 64A of a driving bearing 64 and a sliding bearing 42A, 43A, 44A, 45A or 46A slides to a guiding part 47A, 47B, 47C, 47D or 47E. Thus, a moving means 42, 43, 44, 45 or 46 can be moved between the disk reproducing position D4 in the rear from the inside of a housing case 31X and a disk loading/unloading position D5 of a disk reproducing device 30 in the front from the inside of the housing case 31X. Consequently, the whole disk reproducing device 30 is further miniaturized with a disk housing device 31 of a simple constitution.
