Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a cartridge holder for a recording / reproducing apparatus.

[0002]

2. Description of the Related Art A conventional cartridge holder of a recording / reproducing apparatus will be described in detail with reference to the drawings.

FIGS. 5A to 5C are cross-sectional views showing a first conventional example. The cartridge holder of the recording / reproducing apparatus shown in FIGS. 5A to 5C has a cartridge 10 inside the side walls 103 a and 103 b of the cartridge holder 103.
A predetermined taper is provided in the vertical direction from a position corresponding to the central portion A in the thickness direction of the cartridge 1, and the cartridge 101 and the cartridge holder 103 are in surface contact as shown in FIG. (See, for example, JP-A-8-17119) The cartridge 101 is a resin molded product manufactured by injection molding or the like, and its taper is provided to facilitate removal after molding.

The cartridge used in the optical disc apparatus is formed of a sheet metal, and it is difficult to provide a taper on the end face thereof.

FIG. 6 is a side view showing a second conventional example.
When the cartridge 3 is inserted parallel to the cartridge holder 21 by the cartridge insertion / extraction mechanism 4 but with a step, if the cartridge 3 has a small step and the cartridge insertion / extraction mechanism 4 has a self-compliance function, The cartridge 3 can be inserted into the cartridge holder 21 by sliding the opening 21b.

[0006]

In the above-described cartridge holder of the conventional recording / reproducing apparatus, when the insertion angle or the insertion position (height) of the cartridge is displaced, the cartridge is worn every time the cartridge is inserted or removed, and abrasion powder is generated. Therefore, there is a disadvantage that the optical head of the optical disk device is soiled.

[0007]

A cartridge holder of a recording / reproducing apparatus according to the first invention has a top plate having a first opening for guiding around a cartridge and held by a plurality of springs; And a bottom plate having a second opening for guiding the cartridge around the center and held by a plurality of springs.

[0008]

[0009]

Next, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a side view showing a first embodiment of the present invention. A cartridge holder 1 of the recording / reproducing apparatus shown in FIG. 1 has a top plate 1a having an opening 1d for guiding the cartridge 3 around the center, and held by a plurality of springs 2;
And a bottom plate 1b having an opening 1d for guiding the cartridge 3 around the center and held by a plurality of springs 2.

Even when the cartridge 3 is inserted obliquely, the top plate 1a absorbs this imbalance by the spring 2.

FIGS. 2A to 2D are side views for explaining an example of use of the cartridge holder 1 shown in FIG.
As shown in FIG. 2A, the cartridge 3 is parallel to the cartridge holder 1 by the cartridge insertion / extraction mechanism 4, but when the cartridge 3 is inserted with a step, as shown in FIG. Only the top plate 1a is pushed up to reduce the insertion resistance. When the cartridge 3 is released as shown in FIG. 2C, the cartridge 3 is moved to the normal position by the spring 2, and the cartridge 3 is moved to the normal position.
Is held like

FIG. 3 is a side view showing a second embodiment of the present invention. The cartridge holder 11 of the recording / reproducing apparatus shown in FIG. 3 includes a top plate 11a having an opening 11d for guiding the cartridge 3 at the center and having a plurality of holes, and a top plate 1a.
A plurality of holding plates 6a each having an arcuate spring projecting inward from the hole 1a; a bottom plate 11b having an opening 11d for guiding the cartridge 3 around the center;
And a plurality of holding plates 6b each having an arcuate spring projecting inward from the hole 1b.

FIGS. 4A to 4C are side views for explaining an example of use of the cartridge holder 11 shown in FIG. As shown in FIG. 4A, the cartridge 3 is parallel to the cartridge holder 1 by the cartridge insertion / extraction mechanism 4, but when the cartridge 3 is inserted with a step, the holding plate 6a is pushed upward by an amount corresponding to the displacement of the cartridge 3. Raised to reduce insertion resistance. When the cartridge 3 is released as shown in FIG. 2B, the cartridge 3 is moved to a steady position by the spring 2 and held as shown in FIG. 2C.

The flat portion of the holding plate 6a is welded to the place where the flat plate 11a is in contact with the top plate 11a, and the flat portion of the holding plate 6b is
The part in contact with b is welded.

[0016]

Since the cartridge holder of the recording / reproducing apparatus of the present invention has a self-compliance mechanism on the holder side, the optical head is less likely to be stained by abrasion powder.
