Description

[Detailed description of the invention]

The present invention provides a magnetic tape recording/recording device [1]
Concerning how to use cleaning oil for cleaning. The passage of the magnetic tape through the sound and playback head as well as the drive section (14) is made of iron oxide glass (7).
The child's ('J Rf things are produced 1 '1g and these E' 111st sigma increase and /
Or, it is well known that it gives distortion of No. 118 recorded or played back. Also, due to drive slippage, such markings impair the ability of the tape to pass at the constant speed required for recording or reproducing quality signals. In order to clean these (= 1. At the same time as removing the kimono, also cleaning the component ladle of the recording and/or playback device fh-), various devices including a cleaning cassette are proposed. One type of cleaning cassette is a tank of cleaning fluid that is applied to the tape, as disclosed in a co-filed patent application entitled ``Cleaning Cassette'' by one of the unpublished authors. To clean all assembly and component parts, apply the I/C cleaning liquid to the tape J17.J
It can be used to go to the river. However, the use of such a cassette may result in the user being inattentive to the cleaning liquid being continuously wasted onto the tape; , decreases the efficiency of f+j division. In order to maintain effective cleaning, the cleaning steps listed above must be carefully followed, i.e. by rewinding the tape into the cassette or inserting it into the cassette and tiling it during maximum cleaning. 1! Insert the entire cassette, then turn on the device and complete the cleaning tape.

'+i' is to absorb the usual tensile force. (311) If the cleaning tape is not rewound completely at the start Tj+1 of the cleaning operation, or if the operation is determined, switch the cleaning cassette to a higher speed at Rr. When I put it in,
There is a substantial risk of damage to both the cleaning cassette and the components of the tQ IR.
, it is common to find that it has one different operating method that is not powered (in similar equipment M1, each model has four users IL'), and there It will be appreciated that there may be many causes of handling failure. The main purpose of this 11th light is to control the magnetic tape device and to perform a cleaning cycle using a cleaning cassette.

A force is applied to the surface of the tape in a portion corresponding to the surface of 1/23. The surface of the tape 11 is heated intermittently to prevent the tape from sticking to the drum or tape drive unit 41 that supports the air head of the tape device 1'1 that is being cleaned by the cleaning cassette. . FIGS. 1 and 3 show that according to the present invention, in the magnetic tape device PL, when the cleaning cassette 10 is inserted into the device, the cleaning cycle is completed by rf. 7L as much as possible t+1+s.

It acts as a code member to indicate the cleaning cycle of the cassette 10 by +11 and distinguishes this citrus type cassette from ordinary cassettes in which the four parts 4o are gapped or covered.

At 1 the tape will be nearing the edge of the tape. And'1. The cleaning tape for cleaning the mechanical device rJ is completely obstructed by the supply of a sufficient amount of cleaning liquid to the end of the tape that has passed through the transmission of the cleaning liquid to the device. It is therefore desirable that the Hl 1tG2-11 cycle f+- be started automatically when the cassette is inserted. It also includes: That is, \(a) Completely rewind the cleaning tape in the cassette onto the supply reel 12.

Since it is not possible to create a complete j-v for a more lean jj sevent, it is also desirable to stop the tape at the end of the tape when it reaches nII. This is accomplished by monitoring the movement of the tape by 9+J i'8j Mj or by monitoring the movement of the tape. Therefore, it is also desirable to include the following step 'f'. That is, (less than the total running time for the tape on the tape)
The cleaning tape of the li ll can be viewed with a normal playing screen (with 4 movements). After Jυ, it is necessary to completely rewind the cleaning tape onto the supply reel in preparation for the next cleaning operation.
