Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a magnetic card cleaner for removing stains from the front and back surfaces of the magnetic band portion (generally the magnetic tape attachment portion) of a magnetic card known as, for example, a language learning teaching material.

First, prior to explaining the present invention, the type of card-type player and the magnetic card used therein will be briefly described.

In FIG. 1, 1 is the entire card-type player, 2 is a rectangular ring casing made of resin molded upper half 3 and lower half 4, and 5 is a card transfer slit formed in the longitudinal direction of the upper surface. A magnetic card 6 is inserted into the right side of the slit 5 as shown in the figure, and is caused to travel leftward at a constant speed.

The illustrated magnetic card 6 is a strong sheet rectangular card with a figure 7 and an English word 8 printed on its surface and a magnetic tape 9 pasted parallel to the lower edge. The device 2 is equipped with a card drive system that turns on the power when the magnetic card 6 is inserted, a head, a speaker, an auxiliary electric circuit, etc., and transmits audio signals prerecorded on the magnetic tape 9 of the power source. It is now playable.

Such a card-type player 1 is a playback-only machine that inserts a magnetic card 6 into the above-mentioned slit 5 and runs it for audio-visual learning, for example, for language learning. Various card-type recorders that can be used are already commercially available.

In the figure, 10 indicates a volume heir, and 11 indicates a speaker grill.

By the way, one problem with such a magnetic card system is that various inconveniences occur due to dirt on the magnetic tape portion (generally the front and back surfaces of the magnetic strip) attached to the surface of the magnetic card. can be mentioned.

In other words, the magnetic tape side and the corresponding parts on the back side of the card are always exposed, so when not in use, they tend to attract dirt or come into contact with fingertips when handled, especially when the magnetic card is a teaching material for young children. The tape surface and the front and back sides of the card are often soiled by playing with them.

Therefore, such a magnetic card not only causes dropouts, but also stains the magnetic head, capstan, pinch roller, and other internal materials, and as a result, the brake or recorder cannot function satisfactorily.

The present invention has been made in view of the above points, and its purpose is to propose a new and simple magnetic card cleaner that can effectively clean the front and back surfaces of the magnetic strip of this type of magnetic card. .

Specific examples of the cleaner of the present invention will be explained below with reference to FIGS. 2 to 6.

FIG. 2 is a perspective view showing one embodiment.

In the figure, 12 is the entire magnetic card cleaner having a substantially rectangular planar outline, 13 is its base, and 14 is the base 13.
1 shows a removable cover, which is made of, for example, a molded product of synthetic resin, and has a groove 15 extending from the surface of the cover 14 to the upper surface of the internal base 13 in the longitudinal direction.
[A concave groove 15a on the cover side and a concave groove 15b (FIG. 3) on the base surface are formed.

That is, in this embodiment, the magnetic card 6 is inserted from the right side of the groove 15 as shown by the imaginary line and pulled out to the left, and in the process, the surface of the magnetic tape 9, its upper and lower vicinity, and the corresponding portion of the back of the card are It is designed to be easy to clean.

Therefore, as a specific means for cleaning, place a hygroscopic material, for example, a pair of sponge chips 16 (16a, 16b), 16 (16a, 16b), 1
7 (17a, 17b) so that the respective sets of chips face each other, and the sponge chip 161 at the front position where the inserted magnetic card 6 initially comes into sliding contact is impregnated with alcohol or the like as a cleaning liquid. Then, as described above, the magnetic card 6 is passed through the groove 15 from the right to the left to clean the front and back surfaces of the magnetic strip.

In other words, the sponge tips 16 (16a, 16
b), the adhered contaminants are dissolved and removed, and then the cleaning liquid is absorbed by the dry sponge chips 17 (17a, 17b) at the rear position, and the remaining contaminants are wiped away.

Note that 18 and 19 are the cover 1 at the front and rear of the groove 15.
An inclined surface 4 is formed, and 22 is an arrow mark indicating the magnetic card insertion direction.

FIG. 3 shows the base body 13 of the cleaner of this example, which consists of a rectangular flange-shaped base plate 21, a rectangular protrusion 22 formed in the longitudinal direction at the center of the ridge, and stepped portions on both sides in the front-rear direction. The provided cover engaging portions 23 are integrally molded, and the end surfaces with long means of the cover engaging portions 23 on both sides have hook pieces (not shown) provided on the extension lines of the cover 14.
It is provided with a slit 23' for fastening.

The upper surface of the rectangular projecting body 22 has the recessed groove 15b as described above, and the U-shaped recessed parts 24 (2
4a, 24b) and 25 (25a25b) are formed at predetermined intervals at front and rear positions.

It goes without saying that these recesses 24 and 25 are loading areas for each of the sponge chips 16 and 17 shown in FIG. Considering the case where a material that cannot be formed into a certain shape is used, a chip holder 26 (FIG. 5) for preparing the desired shape is attached to and removed from each recess 24 and 25 in advance. A sponge chip or other hygroscopic material is disposed through the tube.

The holder 26 shown in FIG.
, 24b) and 25 (25a, 25b), but this type of holder is not necessarily required from the basic idea of the present invention.

Figure 4 shows the state of cleaner 1 when cleaning magnetic cards.
2, corresponding parts to those in other figures are given the same reference numerals.

That is, in the illustrated embodiment, the magnetic card 6 is inserted from the front side of the groove 15 (see FIG. 2) of the cleaner 12, and the surface of the magnetic tape 7 and the sponge chips 16a and 16b, which are impregnated with cleaning liquid, are respectively inserted. This shows a process of slidingly contacting the back surface side of that part and allowing it to pass through.

The above is an embodiment of the magnetic card cleaner according to the present invention. However, a material such as a sponge chip may be disposed only on one side of the groove 15, and FIG. 6 shows a summary of one example. This is a route map showing the arrangement relationship of parts. In this example, sponge chips 16 and 17 similar to the previous example are arranged at upstream and downstream positions on one side facing a groove 15 (not shown), and each sponge This is a case where guide rollers 27 and 28 corresponding to the two are provided on the other side, and the passage between them is used as a passage for the magnetic card 6 as shown in the figure.

Even with such a setting, the surface of the magnetic tape can be cleaned, and if the magnetic card 6 is turned over and passed through, the corresponding portion on the back side can also be cleaned.

It should be noted that the present invention may have various other aspects other than those shown in the examples.

In any case, according to the present invention, it is possible to almost completely clean the dirt on the magnetic band part and the back surface of this type of magnetic card with a simple operation, so it is possible to solve the conventional problems as described above, and to use a cleaner. Its structure is extremely simple, making it suitable for low-cost mass production, and its practical effects are significant.
