JPH064976U - Cassette case for video and audio - Google Patents

Abstract

(57) [Summary] [Purpose] To provide a cassette case to meet the demand for time reduction in the manufacturing stage. According to the cassette case of the present invention, a rib 17 'in a portion 18' in which a reel brake member (not shown) is housed is partially removed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cassette case for video, audio, etc., and particularly to a cassette case for shortening a molding time.

[0002]

[Prior art and problem to be solved]

 In general, the cassette case is mainly composed of a guard panel 1, an upper half 2 and a lower half 3 as shown in FIG. There is a demand for these cassette cases to reduce the manufacturing time. Therefore, even if some of the components of the conventional cassette case are removed, the parts that do not change the functions of the conventional product are searched for and cut.

[0003]

[Solution of the device]

 Therefore, paying particular attention to the ribs 4 (FIG. 2) on the upper and lower halves 2 and 3 of the cassette case, the portions where no problem occurs even if removed are cut. By doing so, the amount of plastic required is small, so that the time required to fill the mold with plastic is shortened, and because the friction resistance is reduced, it becomes easier to remove the molded product from the mold. The time can be shortened. Inevitably, it will also lead to cost reduction. Hereinafter, the present invention will be described in detail with reference to the drawings.

【Example】

 4 and 5 show the upper and lower halves 12 and 12 'and the lower halves 13 and 13' of the conventional and inventive cassette cases. These upper and lower halves 12, 12 'and 13, 13' are mainly composed of a tape accommodating portion 11 and 11 'for accommodating a normal tape, outer walls 14 and 14' which form the outline of the cassette case, and an upper and lower portion. The halves 12, 12 ′, 13, 13 ′ are composed of ribs 4 which are stretched vertically and horizontally. The present invention is intended to reduce the manufacturing time, but as a means thereof, paying attention to this rib 4 which is stretched vertically and horizontally inside the cassette case, even if it is partially removed, it is still a constituent element. I searched for a part that does not lose functionality.

As a result, in the upper half 12 ′, the tape running surface rib 16 ′ (FIG. 3), and in the lower half 13 ′, the rib 17 in the portion 18 ′ in which the wound reel brake member (not shown) is housed. 'Was found. As shown in Fig. 2 (b), the rib 17 'of the lower half 13' is assumed to be completely separated or deleted on the way from the continuous one in the past, and the tape running surface rib 16 'is shown in Fig. 3 As described above, a part 20 'of the height of the original rib and a square-filled triangular portion 21' for reinforcing the both ends are left.

[0006]

[Effect of device]

 With the above configuration, the amount of plastic required for each tape is small, so the filling time is shortened, and because the friction resistance is reduced and the molded product can be easily extracted from the mold, It has become possible to reduce the time. In addition, as a result, it will inevitably lead to cost reduction.

Although the preferred embodiments of the present invention have been illustrated and described above, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the technical idea of the present invention. Ah All such changes and modifications should be included in the technical idea of the present invention.
