Description

[Detailed Description of the Invention] This invention relates to an improvement of a cleaning tape type head cleaner, which enables both wet and dry cleaning of the head with a single unit.

The details will be explained below based on the drawings.

The drawing shows an example of a head cleaner for an eight-track playback device, the main body case 1 of which has an outer shape substantially identical to that of an endless magnetic tape cartridge, and has head cleaners on its front and rear surfaces, respectively. In addition to providing an insertion window 2, a capstan insertion window 3, and a sensor insertion window 10, support grooves 11 are provided on each of the left and right sides, and the shape is symmetrical or the same in the front and back so that it can be loaded into the playback device from either the front or rear surface. It is formed in Inside the main body case 1, a tape reel 5 on which an endless wet cleaning tape 4 is wound and a tape reel 7 on which an endless dry cleaning tape 6 is wound are arranged in the front and rear. Guide rollers 8 and pinch rollers 9 are arranged on the front left and right sides and rear left and right sides of the main body case 1, respectively, and the wet cleaning tape 4 is transferred from the tape reel 5 to the main body case through the front left and right guide rollers 8 and pinch rollers 9. 1, and the dry cleaning tape 6 is guided to the tape reel 7 via the guide rollers 8 and pinch rollers 9 on the rear left and right sides inside the main body case 1.
It is led out to the rear side of the main body case 1.

In FIGS. 3 and 4, a water-absorbing material 12 such as felt or sponge with high water retention is pasted on the surface of the guide roller 8 or pinch roller 9 that guides the running of the wet cleaning tape 4. A cleaning liquid supply port 13 is provided on the main body case 1 side corresponding to the end face. now pinch roller 9
If the water-absorbing material 12 is attached to the surface of the cleaning material 12 and the cleaning liquid is supplied only to the corresponding area, the cleaning liquid will seep out onto the cleaning tape 4 due to the pressure of the capstan, so the cleaning liquid will be sufficiently supplied to the cleaning tape 4. To enable efficient head cleaning. At this time, the cleaning liquid supplied onto the cleaning tape 4 does not come out to the head insertion window 2 and the sensor insertion window 10 until the tape 4 has made one rotation, so the cleaning time will be longer, but the cleaning Until the cleaning liquid on the tape 4 comes out, the dry part of the tape 4 to which the cleaning liquid has not adhered will remove any lint, etc., and wet cleaning can then be performed, making it more effective. Cleaning becomes possible. On the contrary, when the guide roller 8 is used as the cleaning liquid supply section, the cleaning liquid supplied onto the tape 4 immediately comes out to the head insertion window 2 and the sensor insertion window 10, so that the cleaning liquid is immediately supplied after the cleaning liquid is supplied. This means that cleaning can be done quickly and cleaning time can be shortened. However, as shown in the figure, both the guide rollers 8 and the pinch rollers 9 may be provided with cleaning liquid supply means so that the user can select the location where the cleaning liquid is to be supplied. Further, instead of these, the tape reel 5 of the wet cleaning tape 4 may be provided with a cleaning liquid supply means.

In such a case, when the front side of the main body case 1 is loaded into the reproducing apparatus, the head can be wet cleaned using the wet cleaning tape 4 led out to the front side. Furthermore, if the rear side of the main body case 1 is loaded into the playback device, the head can be dry cleaned using the dry cleaning tape 6 drawn out to the rear side. In addition to being able to use the dry cleaning tape alone or the wet cleaning tape alone as described above, it is also possible to first remove heavy dirt with the wet cleaning tape 4 and then finish the cleaning with the dry cleaning tape 6. In that case, first load the front side of the main body case 1 into the playback device, clean the head with the wet cleaning tape 4 on the front side of the case, then remove the main body case 1 from the playback device, and then turn it back and forth. Next, the rear side of the case is loaded into the playback device, and cleaning is completed by completely wiping off the cleaning liquid adhering to the head with the dry cleaning tape 6 on the rear side of the case.

Instead of the above embodiment, the dry cleaning tape 6 may be drawn out from the front side of the head cleaner, and the wet cleaning tape 4 may be drawn out from the rear side.

As explained above, in the head cleaner of this invention, one of the wet cleaning tape 4 and the dry cleaning tape 6 is placed on the front side of the main body case 1 inside the main body case 1 which can be used by reversing the front and back. In addition, the other tape is built in so as to be led out to the rear side of the main body case 1. Therefore, a single head cleaner can clean the head using both wet and dry cleaning methods, making it convenient to use. In particular, it is possible to use a cleaning method that improves the cleaning effect by cleaning the head with a wet cleaning tape method and then quickly wiping off the wetted part of the head with the cleaning liquid using the dry cleaning tape 6. It is extremely convenient because it allows playback operations.
