[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a disk loading device and a cartridge of an apparatus for recording and reproducing information on a recording medium such as a disk using optical means.
[0002]
[Prior art]
In recent years, optical disc devices have been widely used as audio discs, video discs, and computer data storage devices.
[0003]
There are two types of optical discs: one that can be recorded / reproduced stored in a cartridge that is mainly used for data storage, and the other that is used barely like a music CD or CD-ROM. With the advancement of multimedia technology, the digitization of AV equipment and the enhancement of the AV function of computers have progressed simultaneously, and the optical disc is also required to have a function as a digital disc that is widely used without distinction between AV equipment and computers.
[0004]
Further, as the miniaturization of not only AV equipment but also personal computers progresses, it is desired to make the optical disc apparatus thinner.
[0005]
Against this background, there has been a strong demand for optical disc apparatuses that are thin and compatible with various types of media.
[0006]
However, conventionally, since a loading method for mounting a disk on a device is different between a disk stored in a cartridge and a bare disk, a dedicated device is required for each.
[0007]
A conventional apparatus will be described below with reference to the drawings.
[0008]
First, a loading mechanism of an optical disk device for cartridges mainly used as a data storage device will be described with reference to the drawings.
[0009]
In general, in such an optical disc apparatus, after the cartridge is inserted into the apparatus, it is necessary to move the cartridge in the direction of the spindle motor and the optical pickup so that the disc is mounted on the turntable so that it can be recorded or reproduced. is there.
[0010]
FIG. 25 is a perspective view showing the structure of the first conventional disk loading mechanism, FIG. 26 is a side view showing the operation thereof, and FIG. 27 is a schematic view showing the dimensional relationship in the thickness direction in the apparatus.

[0015]
When the cartridge 201 is inserted, the lock arm is pushed to one corner of the cartridge to be released. When the lock arm is released, the slider 204 is slid in the direction A by the slider spring 209, the guide roller 203 is moved along the guide groove 205, and the cartridge holder 202 is dimensioned in the direction of the chassis 206 (arrow B). Move by d. At the same time, the support arm 215 is rotated by the slider 204, and the clamper 214 moves in the direction of the turntable 212. When the cartridge is lowered, the disk in the cartridge 201 is placed on the turntable 212 and is mounted in a state where the clamper 214 is attracted and rotated from above, and approaches the optical pickup 213 to a recordable / reproducible distance (see FIG. 26 (b).)
[0016]
When the cartridge is taken out from the apparatus, the slider 204 is pulled back against the tensile force of the slider spring 209 by the loading motor 216, and the clamper 214 and the cartridge holder 202 are raised to the initial position. As a result, the disk is released from the turntable and the cartridge can be taken out.
[0017]
As shown in FIG. 27, when the cartridge 201 is inserted, a distance (dimension D) exceeding the thickness of the cartridge 201 is required between the turntable 212 and the clamper 214.

In this state, as shown in FIG. 19 (2), the holder 100 is gradually housed in the apparatus.
[0119]
FIG. 13C shows a state in which the holder 100 is further accommodated in the disk loading device.
[0120]
FIG. 13D shows a state in which the holder 100 is completely stored in the disk loading device. As shown in FIG. 16D, the rib 100b on the lower surface of the holder 100 is
Contact with the claw portion 12d is disengaged from the rib 8c of the base 8. As a result, the restraint of the slide rack 13 by the clutch 12 is released, and the sliding in the X1 direction becomes possible thereafter. At this time, the shutter 22 is closed, but the rib 36b of the stopper 36 and the protrusion 22a of the shutter 22 are still separated from each other.
[0121]
At the same time, the deformed hole 101b of the holder 100 and the boss 12b of the clutch 12 are engaged as shown in FIG. In this state, as shown in FIG. 19 (3), the rib 101a of the holder 100 and the end 27a of the clamp lever 27 come into contact with each other, the clamp lever 27 rotates about the clamp pressing spring 28, and the clamper 26 turns the turntable.

[0122]
Further, the roller 29 a of the disk restricting member 29 contacts the lower surface 100 d of the holder 100, and the disk restricting member 29 is stored in the base 8.
[0123]
FIG. 14E shows the operation of the slide rack 13 after the holder 100 is completely stored in the disk loading device. As shown in FIG. 16E, the slide rack 13 slides in the X1 direction by the driving force of the drive gear 112a, and the boss 12b of the clutch 12 engaged with the slide rack 13 rotates in the R1 direction. The holder 100 is held at a predetermined position of the base 8 in order to restrict the movement of the holder 100 in the deformed hole 101 b of the holder 100. With the movement of the slide rack 13 in the X1 direction, when the elevating cam 10 engaged with the boss 10b and the groove 13c of the slide rack 13 rotates in the R1 direction about the shaft 8a of the base 8, the chassis 3 is inclined. 10a contacts with the groove 3b of the chassis 3 and gradually lifts from the inclined state to the substantially horizontal state in accordance with the rotation of the elevating cam 10 while resisting the urging force of the torsion leaf 11.
[0124]
At the same time, the stopper 36 is also rotated in accordance with the rotation of the elevating cam 10, and the rib 36 b is close to a position facing the protrusion 22 a of the shutter 22 from a position away from it. At this time, if the shutter 22 is intentionally opened, the rib 36b of the stopper 36 and the protrusion 22a of the shutter 22 come into contact with each other, and the operation of the elevating cam 10 that forms the link mechanism with the stopper 22 is hindered. Not complete. If the loading motor 111 is stopped or reversed by the central processing unit 34, the risk of touching the rotating bare disk 301 can be avoided.
[0125]
FIG. 14F shows the movement completed state of the slide rack 13. As shown in FIG. 16 (f), the movement of the slide rack 13 in the X1 direction by the driving force of the driving gear 112a is completed, and the chassis 3 is placed on the horizontal plane of the inclined rib 10a by the rotation of the elevating cam 10 in the R1 direction. And the chassis 3 is in a substantially horizontal state. The rib 10a of the elevating cam 10 contacts the drive detection switch 23b when the loading operation in which the chassis 3 is substantially horizontal is completed, and the central processing unit (MPU) 34 stops the loading motor 111. In this state, as shown in FIG. 19 (4), when the rotation of the chassis 3 is completed, the chassis 3 becomes substantially horizontal, the turntable 2a on the chassis 3 rises to a position facing the clamper 26, and the cartridge is detected. The circuit board 18 rises from the base 8 by the restoring force of the switch circuit board support 17 and rises to a predetermined position in the holder 100, and the loading operation is completed.
[0126]
At the same time, the stopper 36 also rotates in accordance with the rotation of the elevating cam 10, and the rib 36b stops at a position facing the protrusion 22a of the shutter 22 with a predetermined distance. When the shutter 22 is on the fixed side and the stopper 36 is on the movable side via the damper 9, it is necessary to take into account the impact variation as the two contact distances. In this state, since the rib 36b and the protrusion 22a are close to each other, the contact distance cannot be opened greatly even if the shutter 22 is intentionally opened. The danger of touching the bare disk 301 inside can be avoided.
[0127]
The discharging operation of the holder 100 is performed in the reverse order to these operations. Loading mode
When the slider 111 rotates in the opposite direction, the slide rack moves in the X2 direction, the lifting cam 10 is rotated in the R2 direction, and the chassis 3 is rotated in the Z2 direction. When the movement of the slide rack 13 in the X2 direction is completed, the holder 100 starts to move in the X1 direction by the driving force of the driving gear 112a, and the boss 12b of the clutch 12 that has restrained the holder 100 by the deformed hole 101b of the holder 100 is R2.

[0129]
As shown in FIG. 20 (a), the reverse insertion preventing rib 102a is arranged so as not to contact the discs stored in the openings 300d and 300e of the cartridge 300 inserted in the normal use direction.
[0130]
As shown in FIG. 20B, when the cartridge 300 is inserted into the holder 100 upside down as long as the both sides are opened so that the shutter engaging portion 300b and the rib 103b of the shutter opener 103 abut on the back side of the cartridge 300, the cartridge 300 is stored in the holder 100 without any problem.
[0131]
When the cartridge 300 that is opened on one side or on both sides other than the above is inserted into the holder 100, the shutter opener 103 rotates without opening the shutter 300a. The reverse insertion preventing rib 102a abuts against the shutter 300a during the rotation of the shutter opener 103, so that the insertion of the cartridge 300 is hindered and the complete mounting on the holder 100 is not performed. In this state, since the cartridge 300 is half inserted into the holder 100, the inner protrusion 104f of the rear end portion of the disc holder 104 is spread by the side surface of the cartridge 300, and the outer protrusion portion 104e is extended to the side surface of the holder 100. Since it protrudes to engage with the side hole 8h of the base 8, the movement of the holder 100 into the apparatus is restricted.
[0132]
When the cartridge 300 is pulled out of the holder 100, the restraint of the holder 100 is released in the reverse procedure of this operation.
[0133]
In addition, FIG. 1 As shown in the figure, when the cartridge 300 is inserted into the holder 100 in the reverse direction, the shutter opener 103 cannot open the shutter 300a by the insertion of the holder 100 and rotates, and the reverse insertion preventing rib 102a and the shutter 300a come into contact with each other. As a result, the insertion of the cartridge 300 is hindered and the complete mounting on the holder 100 is not performed. Since the cartridge 300 is half-inserted into the holder 100, the inner end 104f of the rear end of the disc holder 104 is expanded by the side surface of the cartridge 300, and the outer protrusion 104e protrudes toward the side of the holder 100. Since it engages with the eight side holes 8h, the movement of the holder 100 into the apparatus is restricted.
[0134]
When the cartridge 300 is pulled out of the holder 100, the restraint of the holder 100 is released in the reverse procedure of this operation.
