DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card shutter mechanism, and more particularly to a card reader mechanism incorporated in a card-type vending machine, a card-type public telephone, and the like, and a card shutter mechanism of a card processing device.

[0002]

2. Description of the Related Art In recent years, a card shutter mechanism has been proposed which prevents a second card from being inserted during card processing in order to prevent the occurrence of a failure in the apparatus itself or a card jam. Such a card shutter mechanism includes a shutter plate or a shutter pin for opening and closing a card transport path,
Most commonly, a driving means for driving the card is used. When the first card is taken into the card conveyance path, the driving means operates the shutter plate or the shutter pin, thereby closing the card conveyance path. This prevents the insertion of the second card.

A conventional card shutter mechanism will be described with reference to the drawings.

FIG. 4 is a schematic perspective view showing an example of a conventional card shutter mechanism.

FIG. 4 shows a conventional card shutter mechanism 20 disclosed in Japanese Patent Laid-Open Publication No. Hei 3-58184. The conventional card shutter mechanism 20 is disposed along an outer surface of a side plate 44 and extends in a front-rear direction. Free transmission shaft 21 and this transmission shaft 2
A pair of mounting members 21 a and 21 b formed in a substantially Ω shape that rotatably mounts 1 on the side plate 44, a movable member 22 mounted on the rear end of the transmission shaft 21, and a front end of the transmission shaft 21. It is composed of an operating member 23 and a spring 24 that imparts a rotational behavior in the direction of arrow A (counterclockwise) to the transmission shaft 21. The movable member 22 is provided integrally with a rod-shaped main body 22 </ b> A extending in the card conveying direction and provided at the center of the outer surface of the main body 22 </ b> A and extends downward. The main body 22A protrudes into the card transport path from the long hole 26 formed in the side plate 44 and extending in the front-rear direction. Also,
A V-shaped groove 27 that guides one side edge of the magnetic card 38 is formed on the inner surface of the main body 22A facing the card transport path over the entire length in the longitudinal direction. The main body 22A is normally set and held such that the front end bottom 28a of the groove 27 is substantially flush with the inner surface of the side plate 44 or slightly outside the card transport path, and the rear end bottom 28b projects into the card transport path. Have been.

The operating member 23 is formed on a square rod, one end of which is fixedly connected to the front end of the transmission shaft 21, and the other end of which is inserted into the housing 41 through the opening 30 provided in the side plate 44. A pin 31 constituting a shutter portion is integrally provided to protrude. The pin 31 is located behind and close to the card insertion / return port 36 and below the card transport path, thereby enabling insertion of the first card.

[0007]

The conventional card shutter mechanism requires a working member, a movable member, a spring, and the like, which constitute a shutter portion. Therefore, there is a problem that the number of parts increases and the mechanism becomes complicated. there were.

An object of the present invention is to provide a card shutter mechanism in which the number of parts is reduced and the mechanism is simplified and downsized (space saving) in order to eliminate the above-mentioned problems. is there.

[0009]

A card shutter mechanism according to the present invention is fixed to a fulcrum inside a housing of an apparatus to which one end is applied.
At the other end, a shutter plate that opens and closes the card insertion and return port
Extending near the electromagnet and using the fulcrum as a fulcrum
An L-shaped plate-shaped movable member that can be restored by spring force
The movable member is pulled by the shutter plate
To close the card slot and release the electricity
And the electromagnet for restoring the movable member with the spring force
The it has.

Next, the present invention will be described with reference to the drawings.

FIG. 1 is a sectional view showing a card shutter mechanism of one embodiment of the present invention, FIG. 2 is a top view showing the card shutter mechanism of this embodiment shown in FIG. 1, and FIG. 3 is a card of this embodiment. FIG. 5 is a diagram illustrating a state in which a shutter mechanism is operated.

Referring to FIGS. 1, 2 and 3, the card shutter mechanism of this embodiment has an electromagnet 1 fixed to a cover 5 of an apparatus to which this embodiment is applied, and one end fixed to a fulcrum 10 of the cover 5. an L-shaped plate-like movable member 2 which has a shutter plate 2a for opening and closing the card insertion and return opening 7 to restore the movable spring force fulcrum 10 extends to the top of the electromagnet 1 as a fulcrum at the other end is have.

The upper cover 5 and the lower base 6 of the apparatus to which this embodiment is applied are composed of left and right side plates (not shown).
The card insertion / return port 7 and the card transport path 3 are formed, and various mechanisms and parts such as a card insertion detection sensor and a card take-in mechanism (not shown) are installed in the back of the card transport path 3. Have been. The cover 5 has a through hole 8 at the tip of the shutter plate 2a, and the base 6 has a shutter plate 2a.
The groove 9 which escapes the tip of a is formed.

Next, the operation of the card shutter mechanism of this embodiment will be described with reference to FIGS. 1, 2 and 3.

When the first magnetic card 4 is inserted into the card insertion / return slot 7, the magnetic card 4 is taken into the apparatus by a card taking-in mechanism (not shown) and is carried to the back along the card carrying path 3. .

At this time, when the magnetic card 4 passes over a card insertion sensor (not shown), the electromagnet 1 is energized and excited as shown in FIG. 3 to be set and held above the electromagnet 1 (movable member). ) Attract 2 As a result, the leading end of the shutter plate 2a projects into the card transport path 3, and closes the card transport path 3. Therefore, when the second card is inserted after the first card, the second card comes into contact with the tip of the shutter plate 2a, and further insertion is prevented.

After the card processing is completed, when the magnetic card 4 is returned, the magnetic card 4 is detected by a card insertion sensor (not shown).
When the power supply to the movable member 2 is released, the movable member 2 is restored by the spring force, and the card transport path 3 is opened. Therefore, the magnetic card 4 is returned from the card insertion / return port 7.

As described above, the card shutter mechanism of the present embodiment can reduce the number of components compared to the conventional example, and can achieve simplification, downsizing, and space saving of the mechanism.

In the above-described embodiment, the case where the movable member 2 is arranged on the cover 5 above the card conveying path 3 by the arrangement with the electromagnet 1 has been described. However, the present invention is not limited to this. 3 may be arranged below or on the side.

As a card to be used, not only a prepaid card such as a telephone card, but also an IC card, a cash card and the like can be applied.

[0023]

As described above, according to the present invention, one end is suitable.
Card fixed to the fulcrum inside the housing of the device to be used
It has a shutter plate that opens and closes the insertion / return port.
L which can be extended and restored by spring force using the fulcrum as a fulcrum
When the power is supplied, the movable member
Close the card slot with the shutter plate
An electromagnet that restores the movable member with spring force when electricity is released
By having the door, Tozashi closed <br/> the card insertion port to operate the movable member by energizing energizing the electromagnet by the shutter plate, and configured to block insertion of second card,
Furthermore, since the card insertion slot is opened by removing the energization of the electromagnet, the number of parts can be reduced as compared with the conventional case, and
The mechanism itself has an effect that simplification, miniaturization and space saving can be achieved.
