Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a shutter mechanism of a card reader for processing various cards such as a magnetic card, an IC card, and a magnetic / IC card.

[Prior Art] As a shutter mechanism of a card reader of this type for reading and writing magnetic information recorded on a card such as a magnetic card or an IC card, a conventional shutter mechanism is, for example, SAIKAI Sho 61.
No. 152152 is known. As shown in FIG. 5, an abutting portion 3 provided at one end of a shutter 2 rotatably supported by a shaft 1 is normally projected into a card receiving passage 4 so that a card insertion / return opening 5 The inserted card 6 is prevented from further entering, and the shutter 2 is rotated by the solenoid 7 when the card is taken in, and the abutting portion 3 is retracted from the card taking-in passage 4. When the card 6 is taken in, the energization of the solenoid 7 is stopped, the shutter 2 is returned to the initial position by the force of the spring 8, and the abutment portion 3 closes the card taking-in passage 4 again, so that the second sheet Prevents card insertion and removal.

[Problems to be Solved by the Invention] By the way, in such a conventional shutter mechanism,
Generally, the elastic force of the spring 8 is used as the restoring force of the shutter 2. However, in the case of a spring, a space for bending the spring 8 is required, which is an obstacle to miniaturization. Further, in the spring 8, the restoring force of the spring 8 increases as the solenoid 7 presses the shutter 2, and becomes maximum when the shutter 2 is open, which leads to a larger size of the solenoid 7.

In addition, the shaft 1 must be provided and the shutter 2 must be attached, and the spring 8 must be incorporated, resulting in an increase in the number of parts and the number of assembly steps.

Therefore, the present invention has been made in view of the above-described conventional problems, and the purpose thereof is to make the solenoid itself have a shutter function, thereby simplifying the mechanism, reducing the size, and reducing the number of parts. It is an object to provide a shutter mechanism for a card reader that enables reduction.

[Means for Solving the Problems] The present invention has been made to achieve the above object, and the first invention thereof is a magnet embedded in the card guide surface immediately after the card insertion slot, and this magnet. And a solenoid for controlling the opening and closing of the card intake passage. The movable member of the solenoid descends by its own weight when the solenoid is not excited and is attracted to the magnet to attract the card. The insertion passage is closed and the card insertion passage is opened by being separated from the magnet during excitation.

Further, in order to achieve the above object, the second invention is provided with a solenoid and a magnet which are arranged immediately after the card insertion opening so as to face each other with a card intake passage interposed therebetween and which controls opening and closing of the card intake passage, the solenoid being a magnet. The movable member of the solenoid disposed below the magnet lowers by its own weight in a non-excited state of the solenoid and separates from the magnet to open the card intake passage, and is attracted and moved to be attracted and attracted to the magnet when excited. By doing so, the card intake passage is closed.

[Operation] In the present invention, the movable member is attracted when the solenoid is energized to open or close the card intake passage.

[Embodiment] Hereinafter, the present invention will be described in detail based on an embodiment shown in the drawings.

FIG. 1 is a cross-sectional view of an embodiment of a shutter mechanism according to the present invention immediately after a card is inserted, FIG. 2 is a cross-sectional view of an essential part showing a state when a card is loaded, and FIG. 3 is a sheet magnet and a shutter. It is a top view which shows the positional relationship with a mechanism. In these figures, 10 is a card insertion port member attached to the front surface of the apparatus housing 11, and this card insertion port member 10 has a slit-like shape having a width and a height for allowing the card 6 to be inserted and returned. A card insertion / return port 5 is formed. The card insertion / return port 5 is provided inside the device housing 11.
Card taking-in passage 4 communicating with the card, and card processing conveying passage 12
Are formed continuously and substantially horizontally, and a card insertion detection sensor 13 that detects a card 6 inserted through the card insertion / return opening 5 in the card intake passage 4 and determines whether or not the card is a normal card And a shutter mechanism 14 which is provided at the boundary between the card taking-in passage 4 and the card processing and conveying path 12 and normally closes and closes the card taking-in passage 4, and the card 6 is inserted in the card processing and conveying passage 12. A card carrying means 15 for taking in and reciprocating, a magnetic head (not shown) for recording and reproducing for reading and writing magnetic information recorded on the card 6 and the like are provided.

As the card insertion detection sensor 13, in the case of the present embodiment, an example in which a photocoupler including a light emitting element 13A and a light receiving element 13B which are vertically opposed to each other with the card receiving passage 4 sandwiched therebetween is used. Various modifications are possible without being limited to this.

The shutter mechanism 14 includes a sheet magnet 17 embedded in the surface of a card guide plate 16 that guides the lower surface of the card 6.
And a solenoid 18 disposed above the sheet magnet 17 so as to closely face each other with the card intake passage 4 interposed therebetween.
It consists of and. The sheet magnet 17 is assumed to have a weak magnetic attraction, and is arranged so as to be located far away in the width direction of the card from the magnetic stripe 20 which is the information recording portion of the card 6, as shown in FIG. Is set flush with or slightly lower than the surface of the card guide plate 16.

The solenoid 18 is the card insertion detection sensor 1
It is operated by a card detection signal from the device 3, and is composed of an exciting coil 21, a yoke 22, a movable member 23 slidably inserted in a central hole of the yoke 22, and the like, and is fixed to a bracket 24. At the lower end of the movable member 23, a collar portion 23A having substantially the same size as the sheet magnet 17 is provided.
Are provided integrally. Then, the movable member 23 normally descends due to its own weight and the magnetic attraction force of the sheet magnet 17 when the exciting coil 21 is not excited, and the collar portion 23A is adsorbed and held by the sheet magnet 17, whereby the card take-in is performed. The passage 4 is closed.

In this case, although the flexible sheet magnet 17 formed of rubber or the like is used as the magnet in this embodiment, it is needless to say that the magnet is not limited to this and may be a magnet made of ferrite or the like.

The card transport mechanism 15 includes a plurality of rollers 27a, 27b, which are vertically opposed to each other with the card processing transport path 12 interposed therebetween.
. And the conveyor belt 2 stretched between the rollers above the passage.
8, a drive motor (not shown) that drives the conveyor belt 28, a leaf spring 29 that presses the lower roller 27b against the roller 27a via the conveyor belt 28, and the like.

In the card reader having such a configuration, when the card 6 is inserted into the card loading passage 4 through the card insertion / return port 5, the card insertion detection sensor 13 detects the card 6 and determines whether the card is a normal card or not. If the card is a pseudo card, the card reader sends the pseudo card signal to the first card reader to identify it.
The state shown in the figure, that is, the shutter mechanism 14 keeps the card intake passage 4 closed. Therefore, if the pseudo card is pushed in in this state, the insertion end of the pseudo card comes into contact with the peripheral surface of the flange portion 23A of the movable member 23, and further insertion is prevented.

On the other hand, when the card insertion detection sensor 13 determines that the card is normal, a card detection signal is transmitted, and the control unit energizes the solenoid 14 according to the detection signal, and the exciting coil 2
Energize 1. Then, the movable member 23 is attracted and raised by the magnetic attraction force due to this excitation, and is separated from the sheet magnet 17. The rising stroke of the movable member 23 is
The value is set to a value sufficient for the card 6 to pass, for example, about 2 mm. FIG. 2 shows a state in which the movable member 23 is raised. As a result, the card intake passage 4 is opened, and the card 6 is taken into the card processing and conveying passage 12 by the card conveying means 15. Then, when the card 6 is taken in, the energization of the exciting coil 21 is stopped, the movable member 23 is returned downward by its own weight and the magnetic attraction force of the sheet magnet 17, and the card taking-in passage 4 is closed again. Prevent the insertion of the first card.

After the card processing is completed, the traveling direction of the conveyor belt 28 is switched to the return direction, the card 6 is sent backward, and the card 6 is returned from the card insertion / return port 5 through the same path as when the card was inserted. At this time, the control unit sends a signal for executing card ejection to generate the excitation coil 18
Is excited to operate the shutter mechanism 14 and open the card intake passage 4. Therefore, the card 6 is returned to the card insertion / return port 5 through the card receiving passage 4.

FIG. 4 is a cross-sectional view of a main part of a card reader showing another embodiment of the present invention. In this embodiment, contrary to the above embodiment, the sheet magnet 17 constituting the shutter mechanism 14 is embedded with the solenoid 18 in the upper card guide surface 40 forming the card intake passage 4, and the solenoid 18 is arranged below the solenoid 18 so as to face it. It is a thing. The shutter mechanism 14 is provided immediately after the card insertion / return port 5, and the card insertion detection sensor 13 is arranged behind it.

In addition, 41 is a punch mechanism, and this punch mechanism 41 has a punch table 4 arranged above and below the card receiving passage 4 with the punch mechanism 4 interposed therebetween.
It is a conventionally well-known one composed of 2 and a solenoid 43,
By punching a small hole in the card 6 at the end of the service, the balance of the balance information is displayed depending on the punching position.

In the case of the present embodiment, the shutter mechanism 14 normally opens the card intake passage 4 by holding the movable member 23 of the solenoid 18 at the lowermost position by its own weight and holds it for card insertion detection. The solenoid 18 is excited on the basis of a card insertion detection signal from the sensor 13, and when the movable member 23 is attracted to the sheet magnet 17 and attracted to the sheet magnet 17, the card intake passage 4 is closed. This prevents insertion of the second card and also prevents removal of the line fishing card during card processing.

[Advantages of the Invention] As described above, in the shutter mechanism of the card reader according to the present invention, the magnet and the solenoid are closely arranged to face each other with the card intake passage interposed therebetween, and the movable member of the solenoid opens and closes the card intake passage. Since it is configured to control, the structure is remarkably simple, a return spring is not required, the number of parts and the number of assembly steps can be reduced, and the solenoid itself can be downsized. Is large.
