Abstract

PURPOSE:To realize a card reader/writer with high efficiency by employing such configuration that a movable iron core moving perpendicularly in the insertion direction of a card is provided at an electromagnet and the switch of the electromagnet is provided in the neighborhood of a card insertion port. CONSTITUTION:When the card is inserted from an insertion port 3, an operating member 12 is pushed up, and the switch 13 is activated. As a result, the controller of a reader/writer immediately sends a shutter opening signal, therefore, a current flows on the electromagnet 9, and the movable iron core 5 is attracted, and a coil spring 8 is pushed up, and the tip of the iron core 5 is floated over the recessed part of the bottom part of a card feed path 4, thereby, the card can be inserted. In such a way, high efficiency can be obtained and a quick operation can be performed by providing a pin member 6 unified with the movable iron core driven by the electromagnet directly turned on by the operation of the member 12. Also, since no ring mechanism is required, the number of components can be reduced, and assembling can be facilitated.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a card read/write device used for reading and writing IC cards, magnetic cards, laser cards, and the like.

Conventional technology The card read/write device will be explained below.

As shown in FIG. 3, the insertion opening 3 of the cart running path 4 is opened and closed by a plate-shaped shutter 15 by a link mechanism 2 equipped with a spring 14 connected to a movable iron core 5 moved by an electromagnet 9. Arrow C indicates the direction in which the link mechanism 2 moves.

Problems to be Solved by the Invention However, in the above conventional configuration, the movement of the movable iron core 5 by the electromagnet 9 is used to open and close the plate-shaped shutter 15 using the link machine 41!2, so the number of parts is large and the mechanism is complicated. The shutter is complicated, requires a lot of assembly man-hours, and is inefficient.
The drawback was that the opening and closing speed was slow.

The present invention solves the above-mentioned conventional problems, and aims to provide a card read/write device that has a small number of parts, is easy to assemble, is efficient, has a fast opening/closing speed, and can protect the card running path. purpose.

Means for Solving the Problems In order to achieve this object, the card read/write device of the present invention uses an electromagnet that is driven by an electromagnet integrated with a pin-shaped member that moves perpendicularly to the card insertion direction in the card running path. It has a configuration that includes a movable iron core that operates on the electromagnet, and a switch operating member that turns the electromagnet on and off on the side closer to the insertion port than the pin-shaped member.

Function: With this configuration, when a card is inserted, the operating member and switch are activated, the movable iron core is attracted by the electromagnet, and the tip of the pin-shaped member is directly lifted from the bottom of the card running path.

EMBODIMENTS The following will explain one embodiment of the present invention with reference to the drawings. Note that the same reference numerals are used for the same constituent members as in the conventional example.

As shown in FIGS. 1 and 2, a movable iron core 5 integrated with a pin-shaped member 6 is placed inside the card running path 4 following the insertion slot 3 so as to be slidable in the electromagnet 9 in the card insertion direction. is placed perpendicular to. The electromagnet 9 is also fixed to the card read/write device by a circuit board 10 via a plate-like elastic body 11. The movable iron core 5 is pressed by a coil spring 8, and the tip of the movable iron core 5 is in contact with a recess 7 provided on the bottom surface of the cart running path 4.

Inside the card running path 4, a cylindrical actuating member 12 with a dimension longer than the width of the card 1 is disposed closer to the insertion slot 3 than the pin-shaped member 6.
are movable in a direction perpendicular to the insertion direction of the card 1, are arranged so as to be flush with the surface of the card 1, and are provided with a switch 13 which is turned on when the operating member 12 is pressed. Arrow a indicates the direction in which the actuating member 12 moves, and arrow s indicates the direction in which the movable iron core moves.

The operation of the card read/write device configured as above will be described below.

When the card 1 is inserted through the insertion slot 3, the card 1 pushes up the actuating member 12 and the switch 13 is turned on. When the switch 13 is turned on, the control device of the card read/write device immediately sends a shutter open signal, so that current flows through the electromagnet 9. The movable iron core 5 is attracted by the magnetic force of the electromagnet 9, and the coil spring 8 is pushed up, so that the tip of the movable iron core 5 rises from the recess 7 on the bottom of the card running path 4, and the card 1 can be inserted.

As described above, according to this embodiment, the movable iron core driven by an electromagnet integrated with a pin-like member that moves perpendicularly to the card insertion direction is placed in the card running path on the side closer to the insertion slot than the pin-like member. By providing a switch operating section for turning the electromagnet on and off, the operation of the movable iron core by the electromagnet is directly caused by the operation of the pin-shaped member, which is efficient and quick.

Furthermore, since there is no link mechanism, the number of parts is reduced, a compact shutter mechanism is obtained, and assembly is easy.

Further, the card running path can also be formed by an actuating member that is longer than the width of the card and has a circular cross section, which is provided at the insertion opening of the card running path.

Effects of the Invention As is clear from the description of the embodiments above, the present invention is capable of sliding perpendicularly to the card insertion direction, and is integrated with a pin-shaped member pressed against the bottom of the card running path by a coil spring. The structure has a movable iron core inside the electromagnet and a switch operating member for turning the electromagnet on and off near the card slot, which is highly efficient, has a small number of parts, is easy to assemble, and has fast opening/closing speed. It is possible to realize an excellent card read/write device that can quickly protect the card running path from dust.
