JP3056740U - Video cassette tape cleaner - Google Patents

Abstract

(57) [Summary] [PROBLEMS] The present invention enables recording and reproduction by cleaning a tape that cannot be recorded and reproduced due to mold and dust attached to a video cassette tape. SOLUTION: The present invention provides a cleaning table 4 at a position 4a by using solvent cleaning pad cleaners 6 and 7 and wiping cleaners 8 and 9 attached to a solvent pool 10 provided on a cleaning table 4 on a tape of a video cassette tape. Set it between 6 and 7 and between 8 and 9 and apply a cooling fan to the upper part of 8 and 9 to promote evaporation of the organic solvent and detect the tension of the tape while winding the tape with the tape feeding motor and winding motor. Cleans and removes dirt adhering to the tape, enables recording and playback as much as possible, and helps recover valuable assets

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to cleaning a video cassette tape.

[0002]

[Prior art]

 There is a cleaner for the recording / playback head of the VCR, but not for the VCR itself.

[0003]

[Problems to be solved by the invention]

 Video tapes can get moldy due to humid places or dust.If you try to play a videocassette tape that has become moldy, it will not play, and the recording head will be dirty, and the normal video will not work. Recording and playback may not be possible even with cassette tapes. Therefore, the problem is solved by cleaning the video cassette tape that cannot be reproduced due to mold and dust.

[0004]

[Means to solve the problem]

 In this invention, mold and dust attached to the video cassette tape are sandwiched between the front and back sides of the tape with a cloth, paper, sponge, etc., with ethanol or ligroin wetted, and the tape is moved to remove dirt and then dried. Then, the tape is wiped with paper, and the solvent is evaporated with a cooling fan, and the tape is dried and taken up on a take-up reel, thereby solving the problem of mold and dust.

[0005]

[Embodiment of the invention]

 Set the rewound video cassette tape body on the video cassette tape base, open the tape protection shutter, pull out the tape, put the tape on a cloth dampened with a solvent such as ethanol or ligroin, place the tape with paper, sponge, etc. To prevent the solvent from evaporating from the tape, sandwich it between paper and sponge to dry the tape while blowing the air from a cooling fan.Then, use the winding motor and the delivery motor to detect both tape tensions. It controls the rotation speed of the motor and automatically cleans the tape.

[0006]

【Example】

 Hereinafter, an embodiment will be described with reference to the accompanying drawings. Reference numeral 4 denotes a cleaning table, which is set at a position where it is locked by a 19-plate spring, and a video cassette to be cleaned is set in the cassette table 3 so as to be inserted into set pins 28 and 30. At this point, the tape protection of the cassette tape itself is performed. The shutter is opened by 23 and 24, and the mechanism for applying and drying the solvent on the cleaning table is in the state shown in FIGS.

When the knob 5 is moved to the position 5a, the position 22a is locked. This state is the structure shown in FIG. The mechanism of solvent application and solvent drying on the cleaning table is in the state shown in FIGS.

The cleaning device is prepared by moving the tension roller 17 to the position 27a of the knob 27 and locking it to the lock plate spring 18.

[0009]

[Effect of the invention]

 As mentioned above, the video cassette cleaner device of the present invention is an event recording with an important thought that molds the videotape that has become unplayable due to mold and dust attached to the videotape. And so on can be regenerated as much as possible without losing large assets. It is one of the causes of the failure of the videotape deck, so that the rotating recording / playback head can be kept clean.
