Abstract

(57) [Summary] [Purpose] To freely shorten the tape length and eliminate the extra tape portion of a cassette tape. [Structure] The tape winding section has a double structure consisting of an external tape winding section 1 and an internal tape winding section 2, and the unnecessary tape section is wound around the internal tape winding section 2. You can take it away. If the double winding structure is fixed with the latch part 3, the remaining tape is wound on the external tape winding part 1 in the same way as a normal cassette tape, effectively shortening the tape length. Can be done. [Effect] When recording or dubbing music, etc., it is possible to record in time with the actual performance time, prevent unnecessary non-recording time, and therefore eliminate waiting time for non-recording sections.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to cassette tapes used in tape recorders, video cameras, etc. In particular, the present invention relates to a cassette tape whose effective tape length can be freely changed.

0002

[Conventional technology]

Conventional cassette tapes have a pair of winding sections, and the starting and ending ends are separated from each other. Attach the tape to different winding sections and run the tape from one side to the other or vice versa. I'm trying to wind it up. The length of the tape is determined by each cassette tape. It was a long length.

0003

[Problem that the idea aims to solve]

However, with conventional cassette tapes, each tape length is different. For cassette tapes, the recording time is fixed, so each recording time is fixed. There was a problem that adjustments could not be made.

0004 Therefore, for example, when recording music, etc., to avoid cutting off the song midway, If you record within the length of the tape, there will inevitably be some unrecorded parts on the tape. will occur. If you play this with an auto-reverse player, the unrecorded part will be paused. I'm worried about the time, so I have to be patient and wait, or I have to fast forward every time. It has the disadvantage of being time consuming.

[0005] This invention was created in view of the above problems, and allows the tape length to be adjusted. The purpose is to provide a cassette tape that allows the recording time to be adjusted in this manner. shall be.

[0006]

[Means to solve the problem]

In order to achieve the above purpose, the cassette tape of the present invention has a tape winding section. In the case of a cassette tape with There is an internal tape winding section that can wind up the tape, and the tape is pulled through the outer periphery. and has a winding space that covers the winding surface of the internal tape winding section. an external tape winding section rotatably provided outside the internal tape winding section; and connect or disconnect the internal tape winding section and external tape winding section. The structure includes a latch section. In other words, the normal tape winding structure Furthermore, it has a double structure that allows tape to be wrapped inside.

[0007]

[Effect]

According to the cassette tape having the above configuration, the internal tape winding is carried out by the latch part. Release the connection between the tape winding section and the external tape winding section, and then attach the tape to the internal tape winding section. If you wind up the tape and then connect both winding parts with the latch part, the inner tape The tape becomes shorter as it is wound around the take-up section, and in this shortened state, the external tape is The tape can be wound up on the tape winding section.

[0008]

【Example】

Embodiments of the present invention will be described below with reference to the drawings.

[0009] FIG. 1 is an overall structural drawing of a cassette tape showing an embodiment of the present invention. double The structural tape winding section M is similar to the tape winding section of a conventional cassette tape. It is mounted inside the case 5 in terms of external appearance.

0010 FIG. 2 is an enlarged cross-sectional perspective view of a double-structured tape winding section according to the embodiment. It is.

[0011] In the figure, 2 is an internal tape winding part, where the starting end of the tape 6 is fixed. The tape 6 is formed so that it can be wound up. Internal tape winding section 2 A track 7 for transmitting rotational drive is formed inside.

0012 1 is an external tape winding section, and the winding surface of the internal tape winding section 2 is It has a winding space 4 that is exposed and allows the winding, and an internal tape. It is rotatably provided outside the winding section. 9, the tape 6 is pulled through the outer periphery. It is a slit that can be

[0013] 3 is a latch part, which includes an internal tape winding part 2 and an external tape winding part 1. Connect them together so they can rotate together, or disconnect them and wind up the internal tape. It has a function that allows rotation of only one part.

[0014] Therefore, according to the cassette tape according to this embodiment, the normal tape running condition is In the state, the external tape winding section 1 and the internal tape winding section 2 are wrapped as shown in Figure 2. It is fixed by the tape winding part 3, and the external tape winding part 1 is The tape is wound up.

[0015] If the length of the tape is longer than necessary, rewind the tape to the state shown in Figure 2. Next, remove the latch part 3, loosen the internal tape winding part 2 inward, and remove the internal tape. To enable a loop winding part 2 to rotate freely.

[0016] In this state, turn the internal tape winding section 2 to wind the remaining tape. It is wound around the outer periphery of the scraping section 2 and stored in the internal tape winding space 4.

[0017] Then, if you latch the latch part 3 again and run normally, it will wrap inside. The tape in the inserted part cannot come out from inside, so the tape length is short. It becomes. Note that the latch portion may have any configuration.

[0018]

[Effect of the idea]

As explained above, according to the cassette tape of the present invention, the surplus tape can be You can freely shorten the tape length by winding it inside the tape winding section. This allows recording to be performed to eliminate the unrecorded portion of the tape, i.e. the waiting time during playback. This has the effect that the performance time can be set optimally.
