Description

Detailed Description of the Invention

[0001]

The present invention relates to a compact disc,
The present invention relates to a substrate such as a postcard such as a postcard in which an optical disc such as a compact disc graphic is fitted.

[0002]

2. Description of the Related Art A card with an optical disc in which the utility value of the card is enhanced by inserting the optical disc into a card such as a postcard has already been developed by the present inventor. In such a card, the strength and weight of the substrate into which the optical disc is fitted determines the utility value of the card.

That is, because the disc is fitted in the card body, the card must be tough to some extent, and the card is easily damaged during mailing, and there is a risk of damaging the optical disc. Therefore, it is desirable that the substrate is made of hard resin.

Then, the card body is constructed by attaching a communication paper or the like to such a hard resin substrate. However, if the strength of this substrate is too weak, it will be easily damaged, so it is necessary to make it to a certain thickness. However, if the weight is too heavy, the postage will be bulky and the willingness to purchase will be hindered.

Further, when used as a postcard, the back side is a communication field, so it is necessary to make it a flat surface so that it is convenient for writing characters. However, if a flat plate substrate is made of hard resin, it not only has the problem that it is easily warped and the optical disc cannot be completely fitted, but the unit price increases as the amount of resin increases. Becomes Even when it is used as a calender with an optical disc, the back surface must be a flat surface to provide uprights and the like.

[0006]

SUMMARY OF THE INVENTION The present inventor has invented a lightweight and robust card substrate for an optical disk-equipped card so as to provide cards such as postcards with an optical disk that solve the above problems. It was done.

[0007]

In order to achieve such an object, the card substrate of the present invention is provided on a substrate main body 1 having rising edges 2 on four circumferences, and inside the rising edges 2 rather than the rising edges 2. A thin grid bar 3 is provided vertically and horizontally, and an optical disc disc fitting portion 4 having an optical disc engaging portion 5 into which a spindle insertion hole of the optical disc disc is fitted is formed by a partition wall 6 in a central portion. It will be.

A support shelf 61 for supporting the outer peripheral edge of the optical disk is raised on the inner peripheral edge of the partition wall 6, and
An optical disc support plate 8 is formed on the bottom plate of the central portion of the partition wall 6 that comes into contact with the spacer surface of the optical disc by raising it to substantially the same height as the support shelf 61.
An optical disc engaging portion 5 into which a spindle insertion hole is fitted is formed upright in a ring shape, and an optical disc retaining protrusion 51 is provided on the outer peripheral edge of the upper portion of the engaging portion 5. If the upper end of the formula disc engaging portion 5 is bent into a hook shape so as to have a circular hole 9 at the center to form the pressing plate 10, the optical disc can be fitted stably.

Furthermore, if the finger insertion portion 7 is formed by connecting two parallel connecting bars 71 which are provided in parallel with each other from the partition wall 6 to the rising edge 2, the optical disk can be easily taken out. Become.

[0010]

[Operation] Since the present invention is configured as described above, it has the following operations. Since the front and back surfaces of the substrate main body 1 are the flat plate surface and the surface having the lattice bars 3, communication paper having communication and addressing surfaces is attached to the flat plate surface, and a design paper such as a photograph is fitted onto the optical disc board. A card body such as a postcard with a strong optical disk can be formed only by sticking the mating portion 4 on the surface having the lattice bars 3.

Then, the card with the optical disc can be formed by merely fitting the optical disc, which has the pattern corresponding to the pattern paper attached or directly printed on the optical disc disc fitting portion.

Embodiments of the present invention will now be described in detail with reference to the drawings. Reference numeral 1 denotes a postcard-sized substrate body which is made of a hard resin and has a saucer shape having rising edges 2 on four circumferences.

Reference numeral 4 denotes an optical disc board fitting portion,
An annular partition wall 6 is provided at an arbitrary position inside the rising edge 2 except for the finger insertion portion 7. A support shelf 61 for supporting the outer peripheral edge of the optical disc is formed on the inner peripheral edge of the partition wall 6.

Reference numeral 3 is a lattice-like crosspiece that is thinner than the rising edge 2, and is arranged vertically and horizontally except for the partition wall 6 inside the rising edge 2. The crossing portion 31 of the lattice bar 3 increases in strength when fleshed and has sufficient strength even if the lattice bar 3 is thin.

The bottom plate of the central portion of the partition wall 6 which comes into contact with the spacer surface of the optical disc is raised to substantially the same height as the support shelf 61 to form the optical disc support plate 8 and the support plate 8 An optical disc engaging portion 5 into which a spindle insertion hole is fitted is formed by standing upright in an annular shape on the upper side,
A protrusion 51 for preventing the optical disc from coming off is provided on the upper outer peripheral edge of the engaging portion 5, and the upper end of the optical disc engaging portion 5 is
The pressing plate 10 is bent into a hook shape so as to have a circular hole 9 at the center.
Is formed.

Then, slits 11 are provided radially from the pressing plate 10 to the peripheral edge of the optical disc support plate 8 in the vicinity of the engaging portion, and adjacent slits 1 are provided in the vicinity of the engaging portion.

Good.

[0019]

Since the present invention has the above-mentioned structure, it has the following effects.

Since the rising edge 2 of the substrate body 1 is made thicker than the lattice bar 3, the outer periphery of the substrate is strengthened, so that it is difficult to warp.

If the substrate is a mere flat plate, there is a risk that it will be broken by a slight impact, but in the present invention, the optical disc fitting portion surface is provided with a space by the vertical and horizontal lattice bars 3. Even if the substrate body 1 is thin, the strength is increased, and the substrate body 1 will not be cracked by a slight impact and can be safely mailed as a postcard. Further, since it has such a structure, it can be used as a postcard simply by sticking the front and back sheets on both sides of the substrate, which makes it possible to reduce the weight and save the postage, which is economical.

Since the optical disk disc fitting portion 4 is provided with the finger insertion portion 7, the pressing plate 10 is pushed by the belly of the thumb, and the index finger is inserted into the finger insertion portion 7 so that the outer surface of the nail of the index finger rises. By applying the lever to the No. 2 and using the lever, the optical disc disk can be easily taken out by simply raising the outer edge of the optical disc with the tip of the nail.

When the optical disc board is fitted to the optical disc board fitting portion 4, the optical disc support plate 8 and the optical disc support shelf 61 are slightly floated from the bottom surface, so that the optical disc Since the signal storage surface of the disc is not damaged, it can be mailed with confidence.

The optical disc support shelf 61 includes a finger insertion portion 7
Since it is installed except for, the optical disc board is fitted in a state that it floats above the bottom plate, so it is easy to insert your fingernail into the gap between the optical disc board and the bottom plate when removing the optical disc. The optical disc can be ejected smoothly because it is included.

Since the bottom plate at the center of the partition wall 6 is raised and the optical disk support plate 8 is provided, when the pressing plate 10 is pressed, it will be lowered to the optical disk engaging portion 5 and the pressing plate. It becomes easy for 10 to tilt inward, and it becomes easy to take out the optical disc.

In the vicinity of the optical disc engaging portion 5 on the bottom plate, the slit 11 is provided so that the adjacent slits are parallel to each other, so that the slit portion becomes large. Therefore, when the pressing plate 10 is pressed, the supporting plate 8 in this portion is likely to be lowered downward with a slight force to increase the pressing effect, and the optical disc can be easily taken out.

If a slit is provided at a position corresponding to the finger insertion portion 7 on the design paper, the finger insertion portion 7 is inconspicuous, and the appearance is improved.
