Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an intermediate value of 1? for cleaning the 01 pot of magnetic tape and/or the cleaning pot of ffG components of recycling +rt. Related to i.

The passage of magnetic tape over components such as recording and playback heads and drive members can cause deposits of iron oxide particles, and the accumulation of these deposits can increase noise and/or It is well known that distortion is applied to the reproduced signal. In addition, such deposits are
Due to the slippage of the drive member, 111 if7M tapes are passed at the speed of a junior who returns to Tokyo for the recording or playback of high-quality signals.

In order to remove these deposits and also to clean the components of the recording and/or playback device), a number of devices including one cleaning cassette are required. There are 4 V's proposed. One type of cleaning cassette incorporates a fixation of cleaning fluid applied to the tape;
1 is used to apply the cleaning fluid to the tape to clean the components. However, the use of such cassettes cautions the user that the cleaning fluid applied onto the tape must be dispensed in one drop on top of the tape. This will reduce cleaning efficiency.

Water-centered and continuous application of cleaning fluid onto the tape is necessary to ensure effective cleaning, and the tape does not stick to rotating parts (capstans, pressure rollers, drums of bidet heads). , the culm Iv wrapped around it
Make the tape sticky. As a result, both the cleaning tape and the components of the device n are generally damaged.

This phenomenon is especially true for playback and recording 1; f heads are 70-10
It has a diameter of 114° at 0° and 1J, 1.500~ per minute.
This is a problem in a bidet cassette recorder mounted on a drum that rotates at a speed of L800 revolutions. When a tape moistened with a cleaning liquid is carried against a drum of a video tape recorder or the like and sticks to the drum, it is immediately driven at the circumferential speed of the drum. It will be appreciated that as a result of the above phenomenon, the tape is completely unwound from the cassette reel hub and wrapped around the drum within a few tenths of a minute. The main disadvantage of this is +irj. That is, the tape is moved from the cassette reel hub at 11rI, usually at a very low speed (
Although it is rewound several centimeters per second, it is undone at a very high rate; (1) posing a high risk of not being able to do so, since the tape is wrapped around the device 1 and inside the cassette, it may not be possible to re-introduce it into the cassette. that it is not possible and that the device
You must take it to the UL1 store.

The main reason for the misfire ξυ1 is to use a cleaning cassette that applies cleaning γ acid to components between the folds without the door sticking to components such as the drum or capstan of a video tape recorder. By offering one, we can eliminate the problem of two feet.

In accordance with the invention, the cassette is provided with a cleaning liquid supply rl&!, shown here as a roller 20 rotatable on a shaft 21 and pushing against a core 22 of absorbent material such as felt or sponge rubber. store. Apply 1 portion of cleaning liquid to the tape (1

The sumo wrestler housing 14 is shaped by a disk-shaped member 32 that is fixed to the base of the housing 14 to allow the introduction of the cleaning liquid into the core 22VJ-χ·1'1-1. The holes 36-A are formed by a number of holes 36-A, which are provided with an opening D 30, for applying the cleaning liquid through the hole 22. 11. Device 3 with a ring
