Abstract

PURPOSE:To miniaturize a tape cassette by providing a pulling member to pull out a recording medium inside the enclosure of the tape cassette, positioning the pulling member inside the enclosure in the first using state of the tape cassette, and positioning the pulling member outside the enclosure in the second using state of the tape cassette. CONSTITUTION:Inside an enclosure 1 of a tape cassette, pulling members 4, 5, and 7 to pull out a recording medium 3 are provided. The pulling members are positioned inside the enclosure in the first using state, namely when the tape is housed, and they are positioned outside the enclosure in the second using state, namely when the tape is pulled out. Consequently only when the tape is pulled out (loaded), a prescribed aperture part can be secured, and at the time of normal tape housing, the aperture part can be miniaturized and practically eliminated. Thus the tape cassette can be miniaturized.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a tape cassette, and particularly to a tape cassette equipped with a tape pull-out mechanism.

[Summary of the invention]

The present invention provides a tape cassette for storing a tape-shaped recording medium, in which a drawer member is provided in the housing of the tape cassette for pulling out the recording medium, and the puller member is inserted into the housing when the tape cassette is in a first use state. ,
In the second usage state, the opening of the tape cassette is made smaller by controlling the tape cassette to be located outside the housing, thereby reducing the size of the tape cassette.

[Conventional technology]

Various types of tape cassettes for storing tape-shaped recording media have been proposed in the past, and FIG. 8 shows an example of an 8 mm tape cassette, showing the back side of the tape cassette. Usually, such a tape cassette is provided with an opening for pulling out the tape, as shown by reference numeral A in the figure. This opening A is designed to have a predetermined space for a guide to be inserted into this part to pull out the tape during loading.

[Problem to be solved by the invention]

However, in the case of such a conventional tape cassette, the above-mentioned opening A is of course necessary at the time of loading, but it is unnecessary after loading.
After loading is finished, it is nothing more than a so-called dead space within the mechanical deck.

However, simply eliminating opening A would make loading difficult, and the guide on the mechanical deck would need to be moved significantly to pull out the tape.

In this way, conventionally, the opening A is always present not only during loading but also during unloading, which has the drawback of increasing the area (volume) of the entire cassette tape, making it difficult to miniaturize.

This invention was made in view of this point, and it is possible to reduce the size by ensuring a predetermined opening only when pulling out the tape, and reducing the size of the opening when storing the tape, thereby virtually eliminating it. The purpose of the present invention is to provide a tape cassette that can achieve the following.

[Means to solve the problem]

The present invention provides a tape cassette for storing a tape-shaped recording medium, with drawer members (4, 5, 7) for pulling out the recording medium (3) into the housing (1) of the tape cassette.
), and the drawer member is configured to be controlled so that the tape cassette is located inside the housing in the first usage state and outside the housing in the second usage state.

[Effect]

Pull-out members (4, 5, 7) for pulling out the recording medium (3) are provided in the housing (1) of the tape cassette. The pull-out member is located inside the casing when the tape cassette is in a first use state, that is, tape is stored, and is located outside the casing when the tape cassette is in a second use state, that is, when the tape is pulled out. As a result, a predetermined opening is secured only when the tape is pulled out (loading), and this opening can be made smaller and virtually eliminated when storing the tape normally, thereby reducing the size of the tape reel 1-. be able to.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail based on FIGS. 1 to 7.

Figures 1 to 3 show an embodiment of the present invention, with Figure 1 showing the tape when it is stored, Figure 1 A being a rear view seen from behind with the lid removed, and Figure 1 B is its side view. Further, FIG. 2 shows the state when the tape is pulled out, FIG. 2A is a rear view as seen from behind with the lid removed, and FIG. 2B is a side view thereof.

In the figure, (1) is the cassette body, (2) is the tape reel, (3) is the tape wound between the reels (2), (
4) is the roller guide, (5) is the drawer lever, (6)
is a guide plate, and (7) is a pull-out pin.

Figure 3 shows the pull-out lever (5), Figure 3A is its front view, Figure 3B is its side view, and Figure 3C.
is its top view. As shown in Figure 3, a roller guide (4) around which the tape (3) is wound is provided at the tip of the pull-out lever (5), and a pull-out pin (7) is provided on the opposite side of the pull-out lever (5). is installed.

As shown in Figures 1 and 2, the pull-out pin (7) protrudes outward from the slit (8) on the side of the cassette body (1), and when the pin is slid forward (towards the top in the drawing), the pull-out lever (5) ) will move in the same direction, and the roller guide (4) attached to the tip of this lever (5) will pull out the tape (3).

Now, as shown in Figure 1, when storing the tape, the drawer lever (
5) etc. are located within the cassette body (1), and the portions corresponding to the openings described above are so small that they are virtually non-existent.

Next, when drawing out the tape (loading), by moving the drawing pin (7) forward as shown in Figure 2, the drawing lever (5) slides forward and the tape (3) is moved forward.
) is extracted. After this, the space B created by pulling out the tape (3) is treated in the same manner as the opening described above, and a predetermined loading operation is performed. Depending on the path system and loading method, a bus system can be stored in this space B. At this time, the lever (5) that has been pulled out can be used as it is, or it can be used by returning it to the position when it was stored. Furthermore, the lid of the tape cassette may be opened and closed by sliding this lever (5).

As described above, in this embodiment, the portion corresponding to the opening of the tape cassette can be reduced in size and substantially eliminated, so that the tape cassette can be made smaller. Furthermore, depending on the loading method and bus system, the cassette can be moved closer to the drum or other bus system parts, making it possible to downsize the mechanical deck itself.

4 to 7 show a second embodiment of this invention,
FIG. 4 shows the state when the tape is stored, FIG. 4A is a rear view as seen from behind with the lid removed, and FIG. 4B is a side view. Also, Figure 5 shows the state when the tape is pulled out, Figure 5 A is a rear view seen from behind with the lid removed, Figure 5
Figure B is a side view thereof. Note that in FIGS. 4 to 7, parts corresponding to those in FIGS. 1 to 3 are designated by the same reference numerals, and detailed explanation thereof will be omitted.

In this embodiment, a drawer guide base (10) is rotatably provided at the tip of the drawer lever (5). For this purpose, a hole (11) is provided at the tip of the lever (5) as shown in Fig. 6, and a hole (12) is provided at the bottom of the guide base (10). Insert the pin (13) and attach the lever (5) and spring retainer (14) (Fig. 7)
A spring (15) is stretched between the pins (13) and the guide base (10) is rotatable about the pin (13) as a fulcrum. Further, a drawer guide (16) for guiding the tape (3) is provided at the tip of the guide base (10).

Now, as shown in Figure 4, when storing the tape, the drawer lever (
5) etc. are located inside the cassette body (1), and the guide base (
10) is also in a closed state, and the portion corresponding to the above-mentioned opening is so small that it practically does not exist.

Next, when pulling out the tape (loading), move the drawer pin (7) forward (upper side in the drawing), the drawer lever (5) will slide forward, and the guide base (1
0) also comes forward. When the guide base (10) starts to come out of the cassette body (1), the guide base (10) is opened by the spring (15) and stands upright, and the pull-out guide (16) attached to the tip of the guide base (10) allows the tape to be removed. (
3) is extracted. FIG. 5 shows a state in which the guide base (10) is completely opened.

After this, the space B created by pulling out the tape (3) is treated in the same manner as the opening described above, and a predetermined loading operation is performed. In this case as well, the bus system can be stored in space B. After loading, pull out pin (7)
By returning the lever to the rear, the pull-out lever (5) etc. return to their original positions (position W in Figure 4) and do not come into contact with the tape.

For this backward return, a spring may be attached to the rear of the lever (5) and the force may be used to return it.

In this way, in this embodiment as well, the portion corresponding to the opening of the tape cassette can be made smaller and virtually eliminated, so that the tape cassette can be made smaller. In addition, the guide base from which the tape was pulled out returns to its loading state and does not come into contact with the tape, which not only eliminates the need for guide precision but also prevents damage. Furthermore, since the drawer lever and the like return to their original positions, the dead space becomes smaller, and the mechanical deck itself can be made smaller.

[Effects of the Invention] As described above, according to the present invention, a drawer member for drawing out the recording medium is provided inside the housing of the tape cassette, and when the tape cassette is in the first use state, the puller member is inserted into the housing of the tape cassette. Since the tape cassette is located outside the housing in the usage state of No. 2, the opening of the tape cassette can be made smaller and virtually eliminated, thereby making it possible to downsize the tape cassette.
