Abstract

PURPOSE:To make the grip position easy to know by providing recessed parts nearly V-shaped when looked from above or below partially on both sides of the body case. CONSTITUTION:A guard panel 2, a grip shelf 3 and grips 4 are provided in the case body 1. The body is provided with the guard panel 2 that protects a magnetic tape stretched in front of the case body 1 consisting of an upper case and a lower case that contain a pair of reels on which the magnetic tape is wound. Further, nearly V-shaped grips 4 are provided partially on both sides of the case body 1. Thereby, the grip shelf 3 can be easily recognized when looked from above, and can be recognized when looked from below too.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a tape cassette containing magnetic tape for audio, video or data recorders, etc.

Conventional technology Traditionally, tape cassettes had a structure in which a magnetic tape stretched over the front of the case body was sandwiched between a front cover and a back cover provided on the front of the case body (for example, Publication No. 60-194787) 0 Below, regarding the conventional tape cassette as described above,
This will be explained with reference to the drawings.

FIG. 6 is a perspective view of a conventional tape cassette.

In FIG. 5, 1 is a main body case, and 2 is a guard panel, which protects the magnetic tape 3 on the front of the main body case 1. 4 is a grip provided on the side surface of the main body case 1, and is used when moving the main body case 1.

The operation of the tape cassette constructed as described above will be explained below.

First, a magnetic tape 2 equipped with a tape cassette transport mechanism 5
A tape cassette 1 is loaded into a recording/reproducing machine. The loaded tape cassette 1 executes required recording and reproduction.

When the required recording/reproduction is completed, the tape cassette 1 is moved so that the next tape cassette can perform recording/reproduction smoothly. When moving the tape cassette, the tape cassette grip 4 has a flat part on the recording/playback machine for non-linking.
It is inserted from both sides into the flat part 7 and moves while being held between the flat parts 7.

Problems to be Solved by the Invention However, in the conventional configuration described above, the grip position cannot be confirmed when viewed from the top or bottom of the tape cassette, and since the inside of the grip 4 is entirely formed of a flat surface, the tape cassette cannot be viewed from both sides. When holding the cassette by holding it, it is difficult to grasp it reliably depending on the shape of the tip of the holding part, and it can only be held from both sides of the cassette body. Furthermore, in order to mold the shape of the grip 4, it is necessary to use a side core in the molding die.
There was a drawback that the mold structure became complicated.

The present invention solves the above-mentioned conventional problems, and
To provide a tape cassette in which the tape position can be clearly determined, the tape cassette can be reliably gripped, and the tape cassette can be easily molded.

Means for Solving the Problems To achieve this objective, the tape cassette of the present invention comprises:
The main case consists of an upper case and a lower case that contain a pair of reels wound with magnetic tape, and a lid that protects the magnetic tape stretched on the front of the main case. It has a configuration in which substantially V-shaped recesses are partially provided on both sides of the plate when viewed from the top or bottom.

Function: With this configuration, the grip position can be easily changed, and the grip shape is formed by the recesses of the upper half and the lower half and the shelf left by the recess, and the shelf is sandwiched from above and below. This will improve the ease of grasping. Furthermore, since the grip shape is composed of a curved surface and a flat surface, burrs are less likely to appear during molding, and moldability is improved.

EXAMPLE An example of the present invention will be described below with reference to the drawings.

FIG. 1 shows the appearance of a tape cassette in one embodiment of the present invention. Note that the same numbers are given to the same parts as in the conventional example. In Figure 1, 1 is the case body, 2
3 is a guard panel, 3 is a grip shelf, and 4 is a grip. Fig. 2 is a partial plan view of the grip IJ, with only the grip shelf section 3 taken out, Fig. 3 is an enlarged plan view of the grip shelf section 3, and Fig. 4 is a sectional view of the main part of section 8-A in Fig. 2. .

The skein 7) tape of this embodiment configured as above is as follows:
As shown in FIG. 2, the grip shelf 3 can be easily recognized when viewed from above, and the grip shelf 3 can also be easily recognized when viewed from below, although not shown.

Next, as shown in Fig. 3, when gripping the case body 1 on both sides with the grips and the grips 3, since the shape of the grips 3 is approximately V-shaped, the tip shapes of the gripping parts are shaped like circles 8 and 9. Even if the size changes, it can be gripped securely with Grip 4. Also, when grasping from the top and bottom, as shown in FIG. 4, the link handle 1o has flanges on both sides of the main body case 1, so it can be easily grasped.

Furthermore, considering the mold for molding the main body case 1, a major feature is that the approximately V-shaped portion is formed with a curved surface, so that no cracks appear during molding.

Effects of the Invention As described above, the present invention partially provides approximately V-shaped recesses on both sides of the main body case when viewed from the top or bottom, so that the grip position can be easily determined and the grip portion can be gripped. Furthermore, the moldability of the main body case is improved, and an excellent tape cassette can be realized.
