Abstract

PURPOSE:To load a cartridge having an optional size by making it possible that one of guide members which are provided to face side end parts of the cartridge is moved in the direction orthogonal to the cartridge moving direction. CONSTITUTION:A pair of guide members 4 and 6 are provided for loading a cartridge 2 to a prescribed position of a recording and reproducing device; and when the cartridge 2 is loaded in the direction of an arrow A, guide members 4 and 6 are arranged to face both side end parts in the (y) direction of the cartridge 2 so that the cartridge 2 is kept correctly on an x-y plane. If a cartridge whose size is smaller than that of the cartridge 2, a pinion 22 is rotated at a proper angle in the direction of an arrow B by a motor 24 to move members 4 and 6 and a stopper 12 in directions of arrows C, D, and E through racks 17, 19, and 21 by the same length. Thus, the cartridge having an optional size is loaded.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a loading mechanism used to mount a cartridge for a disc-shaped recording medium, which is a recording medium for various information, into a predetermined position of a recording/reproducing apparatus.

[Conventional technology]

Disk-shaped media are widely used as recording media for image information, audio information, or other information. When recording information on a disk-shaped recording medium and reproducing information from the medium, the recording or reproducing head is moved along the disk surface while rotating the disk with an axis passing through the center of the disk and perpendicular to the disk surface. By moving the disk in the radial direction, the disk-shaped recording medium is scanned in a spiral or concentric manner.

Disc-shaped recording media such as those described above are used while being housed in a roughly square-shaped cartridge to prevent dust from adhering to them and from scratches during handling and storage. There are many things. The IJ jig is fixedly held on the recording/reproducing apparatus while being attached to the apparatus, and only the disk-shaped recording medium is rotated by a driving means on the apparatus.

[Problem that the invention seeks to solve]

However, there are various sizes and diameters of the disk-shaped recording media as described above, and currently, for example, optical information recording media have diameters of 30 (7) and 20 cr.

Many types of discs are used, such as 12 cm.

These are used depending on the purpose of use, with larger sizes being used to record large amounts of information, and smaller sizes being used when ease of handling and portability are required. The size of cartridges generally differs depending on the size of these disk-shaped recording media.

In conventional information recording and reproducing devices, the loading mechanism of a disc-shaped recording medium is configured to be compatible only with a disc of a specific size. There was a problem that device N was required.

One way to solve this problem is to make the cartridge size of all disks the same as that of the largest disk, but this method does not take advantage of the ease of handling and portability that small disks have. The good qualities of the people are not taken advantage of.

[Failure to solve the problem]

According to the present invention, in order to solve the above-mentioned problems of the prior art, a cartridge is provided oppositely at two side ends of the cartridge in order to guide the movement when attaching and detaching the cart. A loading mechanism for a cartridge of a disc-shaped recording medium is provided, characterized in that at least one of the two guide members is movable in a direction perpendicular to the cartridge movement direction.

〔Example〕

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic perspective view showing one embodiment of a loading mechanism according to the present invention.

In the figure, 2 is a disk cartridge, and a disk-shaped recording medium (not shown) is accommodated in the cartridge 2 in a free state. The recording medium and its cartridge 2 are arranged parallel to the xy plane, and information is recorded and reproduced in this state.

4.6 is a pair of guide members provided for mounting the cartridge 2 in a predetermined position of the recording/reproducing device. If the cartridge 2 is correctly
Grooves in the X direction that correspond to the ends of the cartridge 2 are formed so as to be kept in a plane, and are arranged to face both ends of the cartridge 2 in the X direction. The inlet portions 4a, 6a of the guide member 4.6 are tapered to facilitate insertion of the cartridge 2. These guide members 4, 6 are slidably supported by guide rods 8.9, 10.11 fixed to the recording/reproducing apparatus side.

The guide arms 8.9, 10.degree. 11 are arranged parallel to the X direction, so that both the guide members 4, 6 are movable in the X direction.

Reference numeral 12 indicates the amount of stop to stop the recording/reproducing device at a predetermined position when the IJ jig 2 is installed.

A groove in the X direction corresponding to the end of the cartridge 2 is formed in the stop length -12. The stop z4-12 is also slidably supported by guide handles 14 and 15 fixed to the recording/reproducing apparatus side. The guide rod 14.15
are arranged parallel to the X direction, so that the two? −
12 is movable in the X direction.

A bar 16 extending toward the center of the cartridge 2 in the X direction is fixed to the guide member 4, and a rack 17 is formed at the tip of the bar 16. Similarly, a bar 18 extending toward the center of the cart horn 2 in the X direction is fixed to the guide member 6, and a rack 19 is formed at the tip of the bar 18. Furthermore, Stotsuno +-1
A bar 20 extending toward the center of the cartridge 2 in the X direction is fixed to the cartridge 2, and a rack 21 is formed at the tip of the bar 20. The above three racks 17,1
Binion 22 is arranged so as to mesh with 9.21. The pinion 22 has a rotating shaft in two directions, and can be driven and rotated in both directions by a motor 24 fixedly supported on the recording/reproducing apparatus side. Rack 17 and rack 19 are arranged on opposite sides with respect to binion 22, with groove rank 17.19 meshing with the lower half of binion 22. The rack 21 is arranged on the side shown with respect to the binion 22, and the rack 21 engages with the upper half of the binion 22.

In this embodiment as described above, the cartridge 2 is indicated by the arrow A.
While being guided by the guide members 4 and 6 along the
12, and the mounting is completed. Next, the disk in the cartridge 2 is clamped to a turntable 28 fixed to the rotating shaft of a spindle motor 26 on the recording/reproducing apparatus side by an appropriate clamp f mechanism (not shown). By rotating the turntable 28, the disk is rotated independently of the cartridge 2, and information is recorded or reproduced.

In this embodiment, when installing a cartridge smaller in size than the cartridge 2, the motor 24 rotates the pinion 22 by an appropriate angle in the direction of the arrow B, thereby guiding the cartridge through the racks 17 and 19° 21. Part 4
, 6 and the strike bar 12 by the same distance in the directions of arrows C, D, and E, respectively. Then, in the same way as for cartridge 2, create a small size cartridge 30.
(shown by the two-dot chain line in FIG. 1) can be attached.

If a cartridge larger in size than the cartridge 2 is to be installed, the binion 22 may be rotated in the direction opposite to the arrow B by the motor 24.

According to this embodiment, the guide members 4, 6 and the stopper 12
Since the disk cartridge is always moved by the same distance, there is an advantage that a disk cartridge of any size can be mounted so that its center position is always the same.

In the above embodiment, the guide members 4, 6 and the stopper 12 are moved all at once by the motor 24, but the guide members 4, 6 and the stopper 12 are moved by independent means. Of course it's a good thing.

Further, in the above embodiment, the two guide members 4.6 and the stopper 12 are all movable, but in the present invention, only one of the two guide members is movable, and the other is fixed. You can leave it there. Furthermore, the stopper may be fixed.

〔Effect of the invention〕

According to the loading mechanism of the present invention as described above, a cartridge of any size can be loaded into the information recording/reproducing apparatus.
