Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for producing a card with magnetic tape, in which, for example, a rectangular card has magnetic tape attached to one or both sides thereof, and characters, figures, etc. are printed thereon.

As shown in FIG. 1, a conventional card with magnetic tape 1 includes, for example, a rectangular card 1a made of a relatively strong material, such as cardboard or plastic, with magnetic tape 2A of a predetermined width parallel to the top and bottom edges on the front and back surfaces of the card 1a. 2B is pasted, and in each margin, for example, the foreign language 3a, 3b to be learned is attached.
and figures 4a, 4b, etc. are printed.

Each of the magnetic tapes 2A and 2B has two tracks, and is inserted into the card bus of a card type recorder in the illustrated state and in the reversed state to run, and the standard audio of one track (the teacher's track) is recorded. The learner is able to perform both audio-visual learning while playing the video. Note that the learner can record and play back his/her own voice using the other track. Therefore, regarding a card type recorder using such a magnetic card, it is described in the applicant's earlier application, Utility Application No. 77863/1983, and the above-mentioned magnetic card 1 is described in the card bus set in the card type recorder. It is made to run almost perpendicularly along the

In order to attach the magnetic tapes 2A and 2B to the rectangular card 1a, an adhesive was previously applied to the magnetic tape attachment surface of the rectangular card 1a, and then the magnetic tapes 2A and 2B were attached. Commercially available glue (for example, liquid glue) was used as the adhesive, and was applied, for example, with a brush. Therefore, the adhesive layer does not have a uniform thickness, and slight unevenness occurs on the surfaces of the magnetic tapes 2A and 2B, resulting in poor sound quality when recording and playing back with a card-type recorder using such a magnetic card 1. decrease in wah and
It has appeared in a flurry of events, and is having a significant negative impact on the recording and reproduction Tokushu.

Furthermore, after long-term use, the adhesive leaks from the edges of the magnetic tapes 2A and 2B, contaminating parts such as the magnetic head on the travel path. Furthermore, if the magnetic card 1 is used for a long period of time, the magnetic tape at the tip of the surface to which the magnetic tape is attached will peel off, making the magnetic card almost incapable of functioning. The present invention has been made in view of the above-mentioned drawbacks, and it is an object of the present invention to provide a manufacturing device for cards with magnetic tape that can be obtained by using a special adhesive and through a special manufacturing process. .

An example of the magnetic tape-attached card manufacturing apparatus according to the present invention will be described below with reference to the drawings. FIG. 2 is a route map of an example of the magnetic tape attached card manufacturing apparatus according to the present invention. Processing devices are sequentially arranged from the left side to the right side along the path L, and can be roughly divided into a card supply device 5, a pair of tape supply devices 6A and 6B, a tape pasting device 7, and a magnetic tape.

That is, each of the magnetic tapes 2A and 2B1ζ has a recording section 24, designated 11, which is slightly longer than the longitudinal dimension of the card 1 with magnetic tape, which is a completed product, and a so-called Q signal section 25, whose dimension is shorter than this, 12, which are alternately connected. The recording section 24 has a first track 24a and a second track 24b.
In addition, since a pinhole 25' is bored in the middle position of each Q signal section 25, the Q signal can be detected by optical means consisting of a light emitting source and a light receiving element instead of a magnetic means using a magnetic head, which will be described later. Detection is also possible. Further, the width dimension of the illustrated magnetic tapes 2A and 2B is 6.25 mm. However, Q

A guide roller 28 is provided to adjust the contact angle of the adhesive tape 26 to the magnetic tapes 2A, 2B.

Further, one or both of the guide rollers 28 are formed with a guide groove to prevent the tape from shifting due to the difference in width of each tape. Note that other guide pins or the like may be installed in addition to the guide roller 28. As shown in FIGS. 2 and 5, the cooling roller 23 is also installed on the tape running path, and the heating roller 22 rapidly heats the tape, which is made up of the magnetic tapes 2A and 2B and the adhesive tape 26, to around room temperature. They are used for cooling and are each made up of a pair of rollers.

Specifically, the inside of the roller 23 has a water-cooled or air-cooled structure. After passing through the cooling roller 23, the adhesive layer 26a is completely transferred to the magnetic tapes 2A and 2B, and only the release paper 26b can be peeled off. 32 indicates a release paper collection reel.

This collection reel 32 is designed to wind up release paper 26b that is no longer needed as the magnetic tape is sequentially fed out. In addition, as for the method of adhering the magnetic tapes 2A, 2B and the adhesive 26a, the heating temperature of the heating roller 22 is 100°C.
C. to 120.degree. C., and the contact time of the tape to the heating roller 22 varies depending on the contact angle, but is performed within the range of 0.2 seconds to 2 seconds. The magnetic tapes 2A and 2B that have passed through the cooling roller 23 in this manner are uniformly adhered with a heat-sensitive adhesive 26a on the opposite side of the magnetic film, leaving about 0.2 mm on both sides of the tape width.

At this time, as shown in FIG. 5, the side on which the adhesive is attached to the magnetic tape 2A located at the upper position of the card transfer path L is set so as to be in contact with the card 10 sent out from the card feeding device 5, and the lower side The magnetic tape 2B at the position is also set in a similar relationship. The tape pasting device 7, which is the next step, is configured to be able to completely stick the adhesive tape onto the card 10 sent out from the card feeding device 5. pressure roller 33

That is, these magnetic heads 35a and 35b detect the phase shift (passage time difference) between the tapes on both sides and detect the magnetic tape 2.
This is to synchronize and feed out A and 2B, obtain the timing to feed out the card 10, and make the recording unit 24 correspond to the card. As a means to equalize the buck tension torque of the tape reels 20A and 20B, for example, a brake system 37b with a constant brake pressure is brought into contact with the reel stand 36b of one tape reel 20B, and the reel of the other tape reel 20A is A variable pressure brake shoe 37a is brought into contact with the stand 36a to adjust the sliding pressure of the brake shoe 37a. Specifically, the double-sided magnetic tapes 2A, 2 mentioned above

This difference signal is supplied to the main control device 39, and the sliding contact pressure is controlled by the output signal from the main swing device 39.

Tension regulators 40a, 40b and a plurality of guide pins 41 are disposed on the tape running path between each tape supply device 6A, 6B and each pressure roller 33A, 33B, and each magnetic tape and the magnetic head surfaces on each side to obtain appropriate sliding contact pressure. As is clear from the above, the magnetic tapes 2A and 2B are attached to predetermined positions on the front and back surfaces of the card 10.

Therefore, the double-sided tape must be attached at a predetermined distance from the upper and lower edges of the magnetic tape-attached card 1 (card in this case). Therefore, it is necessary that the magnetic tapes 2A and 2B be separated by a predetermined distance in a direction perpendicular to the plane of the paper, and that their respective positions be regulated. As a specific means, for example, a guide roller 42 for regulating the tape position is installed on the circumferential surface of the pressure rollers 33A, 33B on the tape drawing side.

The above is a description of the tape sticking device 7, and a magnetic tape and card cutting device 8 is connected to the tape sticking device 7 as shown by a broken arrow A.

This cutting device 8 cuts the magnetic tape 2A as a final step.
By cutting both longitudinal ends of the card 10 with 2B and 2B affixed on both sides, a card 1 with magnetic tape of a predetermined size as shown in FIG. 1 can be obtained. For example, as shown in the figure, there is an upwardly U-shaped fixed cutter 5 located below the card transfer path L.

The movable cutter 56 is configured to urge the cylinder 57. Since the movable cutter 56 is provided with the same guide means and return movement means as the vertical movable cutter 45 in the press section, each member is designated by the same reference numeral. Further, inside the upper and lower cutters 55 and 56, for example, a pair of carrier rollers 5'' are provided at left and right positions with the transfer path L in between.

These carrier rollers 5'' are driven by a motor M2 which is turned on and off by the main controller 39, and sequentially transport the finished cards 1 with magnetic tape after cutting and ink to the right. 1 is shown in imaginary lines in Fig. 3, each corner of the magnetic tape-attached card 1 is provided with an appropriate radius.

Keys such as TOP and RESTART are provided, as well as an NG display to warn of an abnormal state of the entire device, but the structure of such a main control device can be constructed using well-known techniques. Although an example of the magnetic tape-attached card manufacturing device has been described above, according to the gist of the present invention, the configurations of the magnetic tape-attached card and the manufacturing device are not necessarily limited to the illustrated embodiments.

For example, in the above example, it was explained that magnetic tape is attached to each of the front and back sides of the card 10 for the card 1 with magnetic tape. According to the spirit of the present invention, it is easy to understand that this is a good thing. Furthermore, although the operation of the press section 35 in the above example is performed intermittently, the rotation system including each carrier roller is temporarily stopped due to this intermittent operation. However, if the press part has a rolling structure, for example, the entire operating system of the tape applying device 7 can be operated continuously without intermittent stops. As described above, according to the present invention, a heat-sensitive adhesive with a release paper is pressed and heated on a magnetic tape base surface, the release paper is peeled off, the heat-sensitive adhesive surface of the magnetic tape is pressed against a card and heated, and the magnetic tape is attached to a card. Compared to conventional cards with magnetic tape, in which adhesive is applied to the card surface in advance and magnetic tape is attached, there are almost no irregularities on the magnetic film surface, and the magnetic tape Since the magnetic head makes good contact, even when recording and reproducing using a card-type recorder, spacing loss is extremely reduced, making it possible to prevent deterioration in sound quality and causes of wow and flutter.

That is, in the present invention, the layer of heat-sensitive adhesive with release paper already has a uniform thickness when the adhesive is attached to the release paper, so there is almost no cause for unevenness. Conventionally, it is difficult to maintain a constant layer thickness because the adhesive is applied with a brush or the like. Furthermore, according to the present invention, by forming the adhesive layer to be slightly narrower than the width of the magnetic tape, the adhesive generated when the adhesive and magnetic tape are bonded together to the card under heat and pressure is reduced. Leakage can be almost prevented. Therefore, when a magnetic card is used in a card-type recorder, components on the travel path, such as the magnetic head, are not contaminated.
Furthermore, since the magnetic tape is attached to the card by thermocompression bonding, the adhesion between the card and the magnetic tape is strong, and the adhesion is uniform over the entire adhesion surface, allowing the magnetic card to last for a long time. Even after using the card for a long period of time, the magnetic tape at the tip of the magnetic tape attachment surface does not peel off, and a beautiful card with magnetic tape can be obtained.
