JPS58199480A - Cassette tape for preventing winding looseness - Google Patents

Abstract

PURPOSE:To prevent winding looseness, by providing shafts which are inserted into and extracted from the tape reels of a cassette and installing an arm which varies in angle greatly according to their motion. CONSTITUTION:Part of the outer circumference of a tape reel 1 are formed to provide six projections. One of them is provided with a shaft 2 to project from other five projections by about 1mm., and a shaft of a device using the cassette tape is entered therein to push in the projection with the shaft 2, which moves an arm 3. When the shaft of the device comes out of the hole of the reel 1, the arm 3 and shaft 2 are push out by a leaf spring 4 and the arm 3 pushes a reel guide 6 to stops the rotation of the tape reel 1 without any play.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a single-wrap sag-preventing cassette tape equipped with a mechanism for stopping the tape wound inside one cassette tape.

Traditionally, cassette tapes do not have a mechanism to stop the tape reel, so even if you are editing or organizing the tape, the tape will continue to unwind.Especially if you leave the tape in place to shut off the car stereo in your car. (The tape winding becomes loose due to the vibration of the tape.) In each case, it is necessary to insert a ballpoint pen-like object into the hole of the tape reel and correct the tape winding slack with one hand. Tape correction or malfunction is very dangerous as there are many cases of one accident.

If the tape becomes loose, the tape may get tangled inside the cassette tape, causing damage to the cassette tape. This was the primary cause of equipment failure.

An object of the present invention is to provide a one-wrap anti-sagging cassette tape which eliminates the drawbacks of the conventional tape and which prevents damage to the cassette tape.

The configuration of this invention will be explained with reference to one drawing, starting from orange.

Figure 1 is an exploded perspective view of the first embodiment showing the main parts of the invention, and Figure 2 is an exploded perspective view of the main parts of the invention.
3 is a front view of the first embodiment shown in FIG. 3, and a perspective view of the first embodiment showing the main parts of the invention.

There are six hole holes in the tape reel (1) (of the cassette) by molding a part of the outer circumference of the tape reel (1). Push in the hole with the shaft (2) so that it sticks out about a millimeter (by inserting one shaft of the device that uses the cassette tape), and make sure that one arm (3) moves by one shaft (2). It's Nishide.

When the shaft of the device used comes out of one hole of the reel (1), 1
The arm (3) and shaft (2) are pushed out by the leaf spring (4), and the arm (3) pushes the reel guide (6) to stop the play and rotation of the tape reel (1).

Place a thin rubber-like non-slip object on the tip of the arm (3).
When installed, there is no need to groove the 1 reel guide (6).

FIG. 4 is a front view of a second embodiment showing the essential parts of the invention.

Compared to the first embodiment), when the arm (3) is pushed by the first axis (2), the arm (3) enters the U-shaped cover (5), but the arm (3) in Fig. 4 The arm (3) has the same shape as the tape reel (1) and becomes like the inner wall of the tape reel (1) when pushed by the shaft (2).

The tape reels (1) of the first and second embodiments are used in the same way as conventional cassette tape reels. There is no need to put a hole in the case, and one title, photo, etc. can be placed on both sides of one case, but the case is easy to put in and take out, and it prevents damage to the cassette tape and equipment failure. Furthermore, there is no problem in putting one roll of anti-sagging cassette tape into a conventional tape case.

Claims (1)

[Claims] This cassette tape has a single roll of anti-sag cassette tape, which is equipped with a shaft (2) that enters and exits the tape reel (1) of the cassette, and is attached with an arm (3) whose angle changes greatly by 1° depending on the movement of the shaft (2).
