Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a magnetic card and an IC.
The present invention relates to a card reader in which a card such as a card in which information is recorded is taken into the apparatus and the card processing unit reads and writes the information of the card, and more particularly to a shutter structure for restricting the taking-in of a second card.

[0002]

2. Description of the Related Art In this type of card reader, while the first card is being processed by the card processing section inside the apparatus which is inserted from the card insertion slot, the second card is intentionally or accidentally changed. If it is inserted through the insertion slot, it may cause a failure of the card reader body, and therefore a shutter is provided to restrict the taking-in of the second card. Among various shutter structures, there is a structure that uses a retractable pin provided in a solenoid for the purpose of simplifying the structure and reducing the manufacturing cost. FIG. 6 is a side view of a main part for explaining a shutter structure of a conventional card reader.

This will be described with reference to the same drawing. Reference numeral 25 is a solenoid, and an electromagnet 26 having a coil wound inside and fixed to the apparatus and a through hole formed in the center of the electromagnet 26 are indicated by an arrow A. It is roughly configured by a drive pin 27 formed of a movable iron core that is movable in the -B direction. Two
Reference numeral 9 denotes a crank-shaped connecting plate. A drive pin 27 is planted substantially in the center of the connecting plate 29, and a shutter pin 30 and a locking pin 3 both having a round bar shape are formed at both ends.
1 and are planted. In such a configuration, when the coil of the electromagnet 26 is energized, the drive pin 27 is attracted in the direction of arrow A, and the tip portions of the shutter pin 30 and the locking pin 31 advance into the card processing passage 7 as shown in FIG. To do.
Therefore, it is inserted from the card insertion / ejecting port 8
The tip of the second card 6B comes into contact with the peripheral surface of the portion of the shutter pin 30 that has advanced into the card processing passage 7, and the insertion of the second card 6B into the card processing passage 7 is restricted.

[0004]

In the conventional shutter structure using the solenoid described above, the solenoid is operable when the solenoid is excited, that is, when the shutter pin 30 is advanced into the card processing passage 7. Voltage is applied. On the other hand, in the state where the shutter pin 30 is once advanced into the card processing passage 7, that is, in the excited state, the solenoid described above is excited so that the minimum voltage that can maintain the excited state is applied due to problems such as heat generation. The applied voltage is lower than when. Therefore, in this excited state, if the second card 6B is inserted and twisted from the card insertion slot / eject port 8, the shutter pin 30 is easily pushed down, and if pushed down, the shutter pin 30 does not recover. Therefore, the second card 6B is inserted into the card processing passage 7.
In particular, when the front end of the card 6B bends downward in the figure when the front end of the card 6B contacts the shutter pin 30, the pressing force F for inserting the card 6B is applied to the shutter pin 30. In contrast, it acts diagonally downward. For this reason, a component force F1 that pushes the shutter pin downward is generated on the shutter pin 30, so that the shutter pin 30 moves toward the electromagnet 26.
The card 6B is pushed downward against the suction force of the card and the card 6B is easily inserted into the card processing passage 7. If the exciting force of the solenoid is increased in order to prevent this, the solenoid becomes large.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to reliably regulate the insertion of a card even though the structure is simplified and the manufacturing cost is reduced. Another object of the present invention is to provide a shutter structure for a card reader.

[0006]

In order to achieve this object, a first aspect of the present invention provides a card insertion opening for inserting a card, a card processing passage communicating with the card insertion opening, and a card processing passage. In a shutter structure of a card reader including a card processing unit for processing a card taken in and a shutter member capable of advancing and retracting in a portion of the card processing passage in the vicinity of the card insertion opening, the shutter member is a solenoid. And a surface of the pin that contacts the tip of the card is formed as an inclined surface that gradually expands outward in the direction in which the pin is inserted. Therefore, when the tip of the card comes into contact with the inclined surface of the pin, a component force in the pin inserting direction is generated on the pin by the pressing force for inserting the card.

According to a second aspect of the present invention, in the first aspect of the present invention, the card processing passage is formed by two card conveying passage members facing each other in the thickness direction of the card to be taken in, and one of the card conveying passage members is formed. The transport path member is provided with a space facing the tip of the pin that has advanced into the card processing path. Therefore, no gap is created between the tip of the advanced pin and the surface of one card conveying path member.

According to a third aspect of the present invention, in the invention according to the first or second aspect, among the intervals between the two card conveying path members, the intervals near the portion where the pin advances into the card processing path. Is formed relatively narrow. Therefore, the advance stroke of the pin can be set small.

Is the second through hole 16 through which the locking pin 31 moves back and forth.
Has been drilled.

Reference numeral 18 denotes an antenna substrate, which wirelessly reads and writes the information recorded in the card 6A taken into the card processing passage 7 and processes the information of the card 6A by a controller (not shown). It constitutes the card processing unit. Reference numeral 20 denotes an elongated rectangular window formed on the upper plate 5 of the lower case 3, and a driven belt 22 stretched between the pair of pinch rollers 21 and 21 from the window 20 faces the card conveyance path 7. There is. A drive belt (not shown) that is in contact with the driven belt 22 is provided on the upper case 2 side, and the card 6A inserted from the card insertion opening / ejecting opening 8 is taken into the card processing passage 7 by both belts, And after card processing, card insertion and ejection port 8
Is configured to be discharged from.

As shown in FIG. 3, a through hole 26a having a large diameter portion and a small diameter portion is provided at the center of the electromagnet 26, and a drive pin 27 fitted and inserted in the through hole 26a.
A compression coil spring 28 is mounted between the electromagnet 26 and
The drive pin 27 is biased in the direction of arrow B. Figure 1
In (b), the solenoid 25 is controlled by a support member (not shown) fixed to the lower case 3 so that the connecting plate 29 is prevented from coming off in the arrow B direction and the electromagnet 26 is dropped in the arrow B direction. Then, it is attached to the upper plate 5 of the lower case 3.

Next, the structure of the shutter pin, which is a feature of the present invention, will be described with reference to FIG. As shown in the figure, when the shutter pin 30 advances into the card processing passage 7, a portion 30a of the shutter pin 30 that advances into the card processing passage 7, that is, the contact portion 30a with which the tip of the card 6B abuts.

Next, the operation of the shutter pin in the card reader having such a structure will be described. In FIG. 1B, the energization of the coil of the electromagnet 26 of the solenoid 25 is cut off in advance, the connecting plate 29 is moved in the direction of arrow B, and the shutter pin 30 and the locking pin 31 are connected to the card processing passage 7. You have exited from. In this state, when the first card 6A is inserted from the card insertion slot / ejection slot 8 and the sensor (not shown) detects it, the drive belt (not shown) and the driven belt 22 are indicated by arrows. Since the vehicle runs in the C direction, the card 6A is taken into the card processing passage 7. When the rear end of the card 6A passes through the second through hole 16, a sensor (not shown) detects this, the coil of the electromagnet 26 is energized, and the connecting plate 29 moves in the direction of arrow A. Therefore, the shutter pin 30 And the locking pin 31 has the first through hole 15 and the second through hole 16.

Therefore, since a component force F2 that pushes the shutter pin 30 upward is generated in the shutter pin 30, no gap is generated between the upper end of the shutter pin 30 and the lower surface of the bottom plate 4 of the upper case 2. Therefore, it is possible to reliably restrict the second card 6B from being inserted into the card processing passage 7 from the upper end of the shutter pin 30. Moreover, at this time, the upper end portion 30 of the shutter pin 30
Since b faces the space 12 of the upper case 2,
It is possible to more reliably prevent the second card 6B from being inserted into the card processing passage 7 from the upper end of the shutter pin 30. Further, since the passage of the portion 11 where the shutter pin 30 advances into the card processing passage 7 is formed relatively narrow, the movement stroke of the shutter pin 30 can be shortened, so that the solenoid 25 can be downsized. It is possible to save power.

When the processing of the information recorded on the card of the first card 6A is completed, the electric current to the electromagnet 26 is cut off, so that the shutter pin 30 and the locking pin 31 exit from the card processing passage 7. . When the drive belt and the driven belt 22 travel in the direction of arrow D, the card 6A
Are ejected from the card insertion / ejecting port 8.

In the present embodiment, the shutter pin 3
In order to move 0 back and forth through the connecting plate 29, the drive pin 27 may be directly used as a shutter pin. Further, although the card 6A is inserted and ejected through the same card insertion port / ejection port 8, the card insertion port and the card ejection port may be provided separately.
