Abstract

PROBLEM TO BE SOLVED: To achieve a finish with a clear boundary even if a protrusion exists on a surface to be subjected to hot stamp by providing a dustproof lid on a front case, a protrusion at the dustproof lid, and a groove around a protruding part. SOLUTION: When a surface E of a dustproof lid 2 is subjected to hot stamp, a hot stamp foil 6 is spread onto the dustproof lid 2 and a rubber 7 that is warmed up by a heater is pressed against the dustproof lid 2 in the direction of an arrow C, thus transferring the hot stamp foil 6 to the dustproof lid 2. In this case, by pressing a rubber 7 where a cut-out 8 that is larger than a protrusion 4 and is accommodated in a groove 5 is provided to a location corresponding to the protrusion 4, hot stamp is not provided between the protrusion 4 and the groove 5, and the hot stamp is cut by the groove 5, thus finishing the boundary clearly.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for opening and closing a lid of a cassette tape insertion / removal unit in an AV apparatus or the like.

[0002]

2. Description of the Related Art The structure of a conventional lid opening / closing device is disclosed, for example, in Japanese Utility Model Laid-Open Publication No. 50-90629, and the like. No consideration was given to hot stamping the product for thermal transfer. For example, the dustproof cover has projections at both ends so that when the cassette tape is inserted, the projections hit the cassette tape so that other parts are not scratched.However, if there is a projection on the surface to be hot stamped, The surrounding area was not uniformly hot-stamped, and the cuts between the hot-stamp-free parts were not uniform, and were not valuable as a product. Also, since the hot stamp is vulnerable to abrasion, the protrusion to which the cassette tape is intentionally applied is also peeled off and the commercial stamp is degraded, so that the hot stamp attached to the protrusion in advance had to be shaved to expose the surface of the molded resin.
In addition, the dustproof cover and the surrounding front case are often designed to have the same finish. However, the dustproof cover cannot be hot-stamped as it is for the above-mentioned reasons.

[0003]

In the prior art described above, when a hot stamping process is performed on a lid, a projection is formed as a separate part, and the projection is attached to the hot stamped lid later, or a finish similar to the hot stamping process. When the lid is formed by resin molding, a method of simultaneously forming a printed film has been used, but in each case, material costs and man-hours have been required, and this has been inevitably expensive. The present invention has been made in view of the above points, and an object of the present invention is to provide an inexpensive lid opening / closing device capable of hot stamping with high design value.

[0004]

The above object is achieved by providing a dust cover 2 on the front case 1, a projection 4 on the dust cover 2, and a groove 5 around the projection 4 as shown in FIGS. You.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention is shown in FIG.
This will be described with reference to FIGS.

The lid opening / closing device of the present invention has a structure (not shown) in which the rotating shaft 3 of the dustproof cover 2 slides on the front case 1 as shown in FIG. Is inserted into the device. As shown in FIGS. 2 and 3, the dustproof cover 2 is integrally formed with a projection 4 protruding from another surface and a groove 5 around the projection 4.

FIG. 3 is a sectional view taken along the line AA of the dustproof cover 2 in FIG. 1 and schematically shows hot stamping.

As shown in FIG. 3, when hot stamping is performed on the surface E of the dustproof cover 2, the hot stamp foil 6 is spread on the dustproof cover 2 and rubber 7 heated by a heater is pressed against the dustproof cover 2 in the direction of arrow C. Then, the hot stamp foil 6 is transferred to the dust cover 2. In the present invention, hot stamping is not performed on the projection 4 and the groove 5 by pressing the rubber 4 with a rubber 7 having a notch 8 which is larger than the projection 4 and fits in the groove 5 at a position corresponding to the projection 4. The boundaries are neatly finished because the stamp is cut off.

FIG. 4 is a cross-sectional view taken along the line BB of FIG. 2, and schematically shows a case where the dustproof cover 2 and the front case 1 are on the same plane and both are hot stamped.

As shown in FIG. 4, a dustproof cover 2 and a front case 1 are provided.
When hot stamping is performed simultaneously on the surface E, a roller is generally used because the hot stamping surface is so large that uniform pressing is difficult. At this time, a jig 10 is placed on the projection 4 and the hot stamping is performed on the dustproof cover 2 and the front case 1. The hot stamp foil 6 is transferred to the dust cover 2 and the front case 1 when the foil 6 is spread and rotated in the direction of arrow D while the roller 9 heated by the heater is pressed against the roller 9. In the present invention, since the jig 10 is placed on the projection 4, no hot stamp is applied to the projection 4 and the groove 5, and the hot stamp is cut off by the groove 5, so that the boundary is finely finished.

[0011]

As described above, according to the present invention, even if there is a projection on the surface to be hot stamped, the groove around the projection becomes a partition of the hot stamp and the boundary is finished finely. Even if rubber notches or jigs are displaced, they will be finished as long as they are within the grooves. As described above, not only quality is guaranteed by a relatively casual operation, but also in terms of price, the price can be reduced without lowering the design, and the practical value is great.
