Abstract

PURPOSE:To facilitate and ensure the loading and unloading of a card-shaped rotary optical recording medium by providing a mechanism for fixing the position of an opposite side of this card when the card is set on a player. CONSTITUTION:A disk base 1 is opened in a card-shape in the middle part, and edges 2 and 3 are provided on the bottom part, and also movable holders 4a and 4b having restoring force for holding the vicinity of an end part of the card between angles 6a and 6b are provided. When the card is to be fitted in, the holders 4a and 4b are pulled by fingers in the parallel direction alpha to the opposed short sides, and the card is fitted in walls 13 and 14 of the opening part, and is brought into contact with the edges 2 and 3. Subsequently, when the fingers are released, the card is pressed and fixed by the holders 4a and 4b with their restoring force. By this method, loading and unloading operation and positional setting and fixing of the card can easily and accurately be carried out.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical rotary card adapter for holding a card-shaped rotary optical card which rotates around a central axis to perform optical recording and reproduction in a concentric or spiral shape.

[0002]

2. Description of the Related Art Conventionally, a CD having a diameter of about 12 cm
A disc-shaped optical recording medium with a diameter smaller than that of a record disc
Although an adapter is used when it is applied to the player, there is a drawback in the adapter when a rotary optical recording medium having a non-disk shape, for example, a card, is applied.

[0003]

That is, since the scissors are provided on the four sides to sandwich the four sides of the card, it is not easy to attach and detach the card. Therefore, an object of the present invention is to provide an adapter in which a card-shaped rotary optical recording medium can be easily attached and detached.

[0004]

To achieve the above object, an optical rotating card adapter according to the present invention is provided with a wall and an edge into which one pair of opposite sides of an optical rotating card are fitted, and another pair of opposite sides of the card. It is characterized in that a movable holder is provided which has an angle sandwiching the vicinity and which fixes the position of the opposite side.

[0005]

Embodiments of the present invention will be described below with reference to the accompanying drawings. 1 is a configuration diagram of an embodiment of an optical rotation card adapter according to the present invention, and FIG. 2 is an explanatory view of a state where a card is fitted in the optical rotation card adapter of FIG. In FIG. 1, the optical rotating card adapter of the present invention has a diameter of about 1
A card-shaped opening, edges 2 and 3, a holder 4a, and a holder 4b are provided in the center of a disc-shaped base 1 of 2 cm.

The holders 4a and 4b can be moved in position while maintaining the restoring force by extension and displacement, and the upper angle 6a and the lower angle 6b provided at the upper and lower ends of the holder 4a sandwich the card near the end thereof. Then, it has a function of pushing the card inward by the restoring force.

For example, the base 1, the holder 4a and the holder 4b
Is integrally molded with a material such as a flexible resin, and the holder 4a,
The holder 4a and the holder 4b are moved by applying a displacement to the base portion 7 of the holder 4b with respect to the base 1, and the restoring action from the displacement pushes the end of the sandwiched card inward of the card. .

The optical rotation recording card has four sides, two long sides of which are shown as a pair of opposite sides A, and two short sides are shown as a pair of opposite sides B. Now, with the origin at the center of rotation 8 of the card, for example, the α axis 9 is set parallel to the opposite side B, the β axis 10 is set parallel to the opposite side A, and the γ axis 11 is set perpendicular to the αβ plane. Is set to θ12, the wall 13 and the edge 2 are provided on the plus β side of the base 1, and the wall 14 and the edge 3 are provided on the minus β side, respectively, as the configuration of the present invention. That is, the opposite side B of the card is fitted between these walls and the edge. These walls are fixed and do not move. The edge may be fixed or movable.

The holder is constructed so that movable holders 4a and 4b, which are long in contact with most of the opposite side A, are provided on the plus α side and the minus α side. Each holder is provided with an upper angle 6a, a lower angle 6b, or both, and the opposite side A of the card is defined by the upper and lower angles or the upper angle and the edge.
Sandwich the neighborhood.

These angles are provided continuously along the opposite side A at the upper end or the lower end of the holder, or dispersed at several places. For convenience of manufacturing, if the upper and lower angle positions are arranged so as not to overlap with each other, integral molding becomes easy. It is desirable that the structure and the position of the holder including these angles are provided so as to be symmetric with respect to the rotation center 8 of the card and also with the α axis 9 in order to realize stable rotation. Similarly, it is desirable that the edges 2 and 3 are also symmetrical.

The holder 4a can be displaced and moved in a direction in which the space 15 provided adjacently is filled, that is, mainly in the plus α direction, and at this time, the displacement causes a restoring force in the minus α direction. On the other hand, the holder 4b is also mainly minus α.
Can be moved by displacing in the direction
A restoring force is generated in the direction. Here, it is desirable to construct the holder so that the absolute values of the restoring forces of both are equal, but this can be easily realized by making the same material and symmetrically.

When the card is fitted into the adapter from the plus γ direction, first, for example, the holder 4a is pulled in the plus α direction with a finger, and further, if necessary, the holder 4b is pulled in the minus α direction, the card is on the plus β side. Wall 13
To the wall 14 on the minus β side, and then the card stops at edges 2 and 3, thus stopping the card from moving in the minus γ direction.

Thus, not only is the card fixed in the plus and minus β directions, but also the card is prevented from falling down and the card is prevented from rattling in both the plus and minus θ directions.

When the finger is released to stop pulling in the holder, the holder returns to the original position, and at this time, the opposite side A of the card is pressed. If the holder has the same restoring force characteristics, the center of the card can be held at the origin of the α-axis 9.

If the original positions of the holders are arranged inside the opposite sides of the card, both holders balance while pressing the card, and the original position and the opposite sides of the card are matched. Then, the card is fixed with no pressure. Although it can be used in any case, it is preferable to apply a slight pressure from the viewpoint of stability when the card is rotated.

In the above process, the walls 13 and 14 also function as guides for sliding movement of the card. This allows the card to slide smoothly.

When the card can be set in the α direction, the edge and the angle of the holder pinch the card so that the card can be prevented from moving in the plus γ direction and the minus γ direction, so that the card can be fixed also in the γ direction. . Thus, with one-touch easy operation,
It can be fixed in any of β, γ, and θ directions. Similarly, when removing the card, it can be easily operated with one touch.

Regarding the edge, the opposite side B is mainly used.
It is possible to provide it not only continuously as shown in the drawing but also to provide it partially or along the opposite side A. In contrast to the above, the α axis may be set parallel to the opposite side A and the β axis may be set parallel to the opposite side B.

[0019]

Since the optical rotary card adapter according to the present invention is constructed as described above, not only can the card attaching / detaching operation and the card position setting / fixing be extremely easy, but also the card can be warped or bent as a result of actual use. It is also found that there is also an effect of correcting the flatness and flattening it, so that the card which is not flat is corrected to improve the reliability of optical recording and reproduction,
Moreover, because it can be realized easily and cheaply, the product has great utility.
