Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) This invention relates to a magnetic card reader / writer for reading and writing magnetic data of a magnetic card used for a telephone card, an orange card, a magnetic card ticket, and the like.

(Prior Art) In recent years, magnetic cards such as telephone cards, deposit cards such as orange cards, and magnetic card tickets have been used in various fields due to advantages such as streamlining operations and collecting information. . However, since these magnetic cards are in direct contact with the hand, sweat, hand deposits, dust, and the like adhere to the magnetic cards, and when passing through the magnetic card reader / writer, dirt adheres and accumulates in the reader / writer. If dirt adheres to the surface of the magnetic material of the magnetic card, the contact gap between the magnetic head that reads and writes to the magnetic card and the magnetic surface of the magnetic card changes, which causes a mistake in reading or writing magnetic data. Trigger.
In order to prevent such mistakes, they are regularly cleaned according to the frequency of use. Cleaning is performed accurately because the dirt on the surface of the magnetic head directly induces mistakes, but other parts, especially the part inside the card slot, prevent two magnetic cards from being inserted. A gap 1.5 times the thickness of the magnetic card (about 0.3
mm), it cannot be cleaned and is often left as it is. Therefore, dirt accumulates inside the insertion slot, and at a certain point, the dirt peels off and adheres to the magnetic card. Since the light passes through the head portion, the above-mentioned reading error and writing error are induced.

An object of the present invention is to provide a magnetic card reader / writer that prevents contamination that accumulates and accumulates inside a card insertion slot, and that reduces magnetic data reading errors and writing errors.

(Means for Solving the Problems) According to the present invention, a card insertion slot for inserting a magnetic card, a card conveying means for conveying the inserted magnetic card,
Reading / writing means for reading or writing magnetic data of the conveyed magnetic card, insertion detecting means for detecting insertion of the magnetic card, card position detecting means for detecting the position of the magnetic card when the magnetic card is conveyed, In a magnetic card reader / writer composed of a controlling device,
In addition to two narrow rails on both sides along the magnetic card insertion direction on the inner surface of the insertion slot, three or more narrow rails formed at positions not opposed to the magnetic tracks recorded on the magnetic card; A dirt drop hole is provided in a groove formed between the rails and a groove facing the lower surface of the magnetic card conveyed by the card conveying means.

Depending on the application, a shutter means for restricting the insertion of the magnetic card, a punching means for indicating the number of times the magnetic card is used, a printing means for indicating the number of uses and the use conditions, and the like are also added to the configuration. Things are also possible.

(Operation) The dirt accumulated and accumulated on the inner surface of the card insertion slot for inserting the magnetic card is peeled off at a certain point, and adheres to the magnetic surface of the magnetic card. , And contaminates the surface of the magnetic head, leading to reading errors and writing errors of magnetic data. However, in this invention, when the magnetic card passes through the insertion slot, the magnetic track of the magnetic card faces the groove formed between the narrow rails and does not directly contact the inner surface of the insertion slot, so that the passage of the insertion slot does not occur. In this case, there is no possibility that dirt accumulated in the insertion opening adheres to the magnetic track, and therefore, the possibility of occurrence of reading errors and writing errors is reduced. Further, even if the dirt is removed, the dirt drop hole is provided, and the dirt is removed to the outside through the dirt drop hole.

FIG. 1 shows an embodiment of the present invention.

Behind the card insertion slot 11, a belt 14 hung on a pulley 12 and a pulley 13 is provided, and a belt 19 hung on a pulley 15, a pulley 16, a motor pulley 17 and driven by the rotating force of a motor 18 is provided. It is. The belt 14 and the belt 19 are in contact with each other with a certain pressure in a part of the passage section. A touch roller 21 is provided above the pulley 12 with a certain pressure, and the belt, the pulley, and the touch roller constitute a card conveying means. A card position detecting sensor 22 for detecting a magnetic card and a magnetic head 23 for reading and writing magnetic data of the magnetic card are provided on a card conveying path of the card conveying means.
A platen roller 24 that applies a fixed pressure to the magnetic card conveyed to the magnetic head 23 is provided above the magnetic head 23. The card insertion slot 11 is provided with a card insertion detection sensor 25 for detecting card insertion.

When the magnetic card is inserted, the card insertion detection sensor 25
Turns ON, the motor 18 is energized, and the conveyor belts 14, 19
Rotates and carries the magnetic card. The magnetic card turns on the card position detection sensor 22A, and after a certain time (when the magnetic card comes over the magnetic head 23), the magnetic head 23 reads the magnetic data of the magnetic card. Card position detection sensor 22B
Is turned on, it is confirmed whether the read data is legitimate data. If not, the motor 18 is reversed and the magnetic card is returned to the insertion slot 11. If the read data is legitimate,
Similarly, when the motor 18 is reversed and the magnetic card passes through the card position detection sensor 22B and is turned off, the magnetic head 23 rewrites predetermined data and then returns the magnetic card to the insertion slot 11. In some cases, a verify operation is performed after data rewriting.

In the present invention, as shown in FIGS. 2 and 3, a groove 33 is formed on the inner surface of the insertion slot 11 at a portion where the magnetic track 32 faces when the magnetic card 31 passes. A plurality of narrow narrow rails (convex portions) 34 are provided along the magnetic card insertion direction between magnetic tracks not related to magnetic writing and near both side portions of the magnetic card. The narrow rail 34 has a narrow width so as to withstand long-term use, and the narrow narrow rail 34 can reduce the adhesion of dust. The dirt drop hole 35 in the groove 33 below the insertion slot 11
The dirt attached to the rail 34 and peeled off is taken out through the dirt drop hole 35.

(Effects of the Invention) As described above, according to the invention, when the magnetic card passes through the insertion slot, the magnetic track does not come into direct contact with the insertion slot due to the presence of the groove 33, so that the dirt on the insertion slot can be reduced. There is no danger of sticking to the data, and reading errors and writing errors are reduced accordingly. Also, due to the presence of the thin rails 34, the contact portion between the insertion slot and the magnetic card is small, so that dirt on the magnetic card is less likely to adhere to and accumulate in the insertion slot. . Further, even if the dirt is removed, the dirt drop hole 35 is provided, and the dirt is removed to the outside through the dirt drop hole. Therefore, there is an advantage that the reading surface of the magnetic head 23 is not stained by dirt, and the occurrence of reading errors and writing errors can be further reduced.
