[Industrial application field]

The present invention relates to a card reader/writer device for magnetic cards, and more particularly to a card reader/writer device capable of storing a plurality of cards.

In recent years, so-called prepaid cards, mainly magnetic cards, have come into widespread use as a means of paying for transportation, communication facilities, etc., but a small card reader/writer device that can store multiple cards at the same time is needed. There is a strong demand for

[Conventional technology]

Card reader/card reader that records and plays data on magnetic cards, etc.
The writer device takes in an inserted card, moves it relative to a magnetic head at a predetermined transport speed within the device, reads and writes data, and then automatically ejects the card. For this reason, the card reader/writer device has a built-in transport means for transporting the inserted card. This is usually done by holding the card under a predetermined pressure between a conveying roller and a pressing roller, which are placed opposite each other, and rotating the conveying roller to convey the card under the recording/reproducing head at a constant speed. It is designed to be taken in and excreted through the mouth.

[Problem to be solved by the invention]

In conventional card reader/writer devices, one card is inserted into the card slot, the card is processed in a predetermined manner, the card is ejected into the same slot, and then the next card is inserted. ．． However, when using a prepaid card to pay charges, etc., if the amount or number of credits is insufficient for one card, 2.
You need to pay with one card.

In this case, first insert the first card into the card reader/writer, and the card reader/writer will read and write the card.
After performing a predetermined payment process such as an ejection operation, it is necessary to insert a second card and perform the same operation, resulting in a problem that the operation is complicated.

There are also card reader/writer devices that have separate card insertion and ejection ports and eject the first card after pulling in the second card, but this requires a longer path to transport the card, and the device There is a problem that the shape becomes large.

The present invention was created in view of the above-mentioned problems, and aims to provide a card reader/writer device that simultaneously stores a plurality of sequentially inserted cards, performs predetermined processing, and sequentially ejects them from a card insertion slot. purpose.

[Means to solve the problem]

The above-mentioned problem is solved by having at least three guide grooves on the inside of both side walls for guiding both side edges of the card, and consisting of a take-in roller, a main roller, a feed roller, and a pressing roller facing each of them, which sandwich and convey the card. In a card reader/writer device in which a pair of rollers are provided in order from the card insertion slot side, the height position of a feed roller that carries in or sends out a card to a card storage section is shifted downward, and the The pressing roller facing the roller is braked by viscous resistance, and the guide groove is provided with an inclined portion inclined downward toward the back side at the entrance of the card storage section. This problem is solved by the card reader/writer device of the present invention.

[Effect]

The feed roller of the card storage section is located slightly below the card transport path, and the guide guide of the storage section has a groove that widens downward due to the sloped part, so the first card in the storage position is positioned slightly below the card transport path. The second card that is stored at the bottom and then conveyed does not get caught on the stored l-th card, and the two cards are stored one on top of the other. When ejecting, the second card on the upper side is driven by the feed roller and sent out, but the second card on the lower side is pressed so that its rear end engages and is in contact with the slope of the guide groove. Since the rollers are braked by viscous resistance, they remain in the storage area, and two sheets are not sent out at the same time.

〔Example〕

Embodiments of the present invention will be described below with reference to the accompanying drawings.

Fig. 1 is a schematic side sectional view showing the main parts of the card reader/writer of the present invention, Fig. 2 is a schematic side sectional view showing the loading operation of the second card, and Fig. 3 is the schematic side sectional view showing the card ejecting operation. FIG.

In FIG. 1, a card 1 has, for example, a magnetic recording medium provided at a predetermined position on its lower surface. 3 is a card reader/writer, which is shown in a side sectional view taken along the card conveyance direction. Both side walls 3 of the card reader/writer housing 34
8 (the figure shows one side wall seen from the inside) is provided with guide grooves 35 for guiding both side edges of the card. 38a is the front wall of the housing where the card insertion slot 38c opens;
38b is the rear wall of the housing. Inside the housing, 3Mi roller pairs 31a, 31b; 32a are arranged along the guide groove 35.
, 32b; 33a. 33b are arranged so as to sandwich the central part of the width of the card at an interval shorter than the length of the card. The upper rollers are the intake rollers 31a in order from the insertion port side.
．． Power is transmitted to the main roller 32a and the feed roller 33a by a drive belt (not shown), etc., and the rollers are synchronously driven to rotate in forward and reverse directions. The lower three rollers are pressure rollers 31b,
32b. 33b, each is provided facing the upper roller, and is always urged upward so that the inserted card is held between the upper roller and the upper roller. Feed roller 33a
is provided at a lower position where the contact surface with the pressure roller 33a is slightly shifted (dimension h) below the straight line connecting the contact surfaces of the two right rollers, and accordingly, the guide groove 34 is also provided in this position. At that part, the groove is lowered downward through the inclined part 36a, and the width of the groove becomes wider, forming the shape of the card storage part 36. A viscous damping means such as an oil damper 33c is connected to the shaft of the pressure roller 33b that is in contact with the feed roller 33a.
A magnetic head that provides viscous resistance is placed at the position of the main roller 32a.

Next, the operation of the card reader/writer device having the above structure will be explained with reference to FIGS. 1, 2, and 3.

In FIG. 1, the first card 1 inserted from the insertion slot 39c is placed between the take-in roller 31a and the pressure roller 3l.
b and is conveyed to the left until the leading edge of the card reaches the main roller 32a. The main roller 732a conveys the card 1 at a predetermined conveyance speed while bringing it into contact with the magnetic head 3#, and during this time, predetermined magnetic data is written and read. When the leading edge of the card reaches the left feed roller 33a, the leading edge of the card abuts against the rear wall 39b by the feeding roller 33a, and the rear end is moved into the storage section 39.
It is transported until it reaches the inclined part 36a at the entrance of the storage part 36
The card is stored in the guide groove of the card, thereby opening a conveyance path for the next card.

In this state, insert the second card 1° as shown in Figure 2. The first card 1, which is processed in the same way and transported to the storage section 36, is stored at the bottom of the passage, so the tip of the second card 1' is the same as the first card 1''1. It is stacked on top of the first card 1 without hitting the rear end.

As shown in FIG. 3, when the card is ejected, if the feed roller 33a is rotated in the opposite direction to the direction when the card is loaded, the friction coefficient between the upper card 1° and the feed roller 33a is large, so the two cards stored on the upper side are rotated. The second card L' is sent out from the storage section 36 with its rear end riding up the slope 36a of the guide groove, fed rightward, and ejected from the insertion port 39. However, the first card 1 stored at the bottom
, the card remains in the storage position due to the braking force from the pressing roller 33a that is in contact with the lower side and the frictional force between the inclined portion 36 and the rear end rather than the frictional force in the ejection direction received from the upper card. Two sheets will not be ejected at the same time. Then, when the second card 1'' is sent out from the storage section 36, the feed roller 33a directly contacts the first card 1, so that it is sent out from the storage section in the same way as the second card 1. I can do it.

Note that the above operation can be performed satisfactorily by appropriately setting the viscous damping force of the oil damper and the slope of the inclined portion.

As explained above, according to the card leaguer/writer device of the present invention, two cards can be successively inserted into the same card insertion slot, and the shape can be made to be approximately the same size as a normal single card device. can. Therefore, if the amount or frequency is insufficient with just one bripaid card, two cards can be inserted from the beginning, and the two cards can be automatically processed. Also, if the amount of information on one card is insufficient, it is possible to supplement by adding another card, or to perform simultaneous processing by sequentially inserting one card for ID and the other for rewriting. It becomes possible. [Effects of the Invention] According to the present invention, it is possible to realize a card reader/writer device that simultaneously stores a plurality of sequentially inserted cards, performs predetermined processing, and sequentially ejects them, and is applicable to prepaid systems, etc. This has the effect of simplifying the procedures for customers.
