The present invention relates to a device for attaching a wear prevention piece of a card reader that checks for an abnormality of a credit card, and more specifically, is inserted into a mold during injection of the main body, The wear prevention piece fixed in one piece can be easily mounted in the mold.

In general, credit cards are becoming more popular as the currency of FIG. 3, and therefore, a means for identifying whether a card generated by a card company is usable should be taken and the device for identifying the card reader is a card reader.

That is, the card reader inquiring the lost card, the expiration date, the expiration date, etc. reads the contents recorded on the card in the reader head and stores the card data (the number of installments, the amount of use, etc.) in the memory, and then the modem ( If you use a public line to transmit to the host computer through the MODEM), the host computer analyzes this data and informs the queryer whether the card is abnormal and available.

1 is a perspective view showing an example of a card reader generally used. On the upper surface of the card reader main body 1, a function key 2 for inputting various inquiry information and a display unit 3 for displaying the inquired information are installed. On one side, the card insertion portion 4 is formed in the same manner.

Therefore, by inputting the information to be inquired using the function key (2), inserting the card (5) in the card insertion unit (4) and linearly moving the card along the card insertion unit to determine whether the card is a usable card. It is shown on the display unit 3.

The main body of the card reader as described above is usually molded of synthetic resin, and the card is inserted into the card inserting portion, and the card is inserted into the bottom surface. Will occur.

Therefore, a wear protection piece for preventing wear should be installed on the bottom surface of the card insertion portion.

2 is a plan view and a longitudinal sectional view showing a card insertion portion of a conventional card reader, wherein one side of the card insertion portion 4 is provided with a head block 6 for reading recording information of the magnetic tape attached to the back of the card. At the bottom of the card insertion section, a metal wear protection piece 7 is provided.

The wear preventing piece 7 is formed long along the longitudinal direction of the card inserting portion, and is inserted into the injection mold during molding of the card reader main body to be integrally formed with the main body.

In addition, a downward bent portion 8 is formed in the insertion portion and the withdrawal portion of the card to facilitate insertion and withdrawal of the card.

However, the wear prevention piece 7 mounted on the conventional card reader has a narrow width and a long length depending on the shape of the card insertion portion, and a separate means for preventing flow of the wear prevention piece in the state of being inserted into the fixed mold. There is a problem that the injection operation is difficult because there is no.

That is, when the wear prevention piece is mounted in the mold for injection of the card reader main body, the wear prevention piece in the form of a flat plate should be mounted on the fixed side mold using a mechanism such as a pin cell. Since there is no convenience flow preventing means, the wear preventing pieces are often separated from the mounting position due to vibration during the movement of the movable mold, and in this case, there is a problem such that the mold is broken.

In addition, since the wear preventing piece 7 is a single body, the wear preventing piece causes interference when the head block 6 is installed, and it is difficult to adjust the installation position of the head block.

The present invention is to provide a wear prevention piece mounting device of the card reader that can be easily mounted in the fixed side mold and prevent the flow even after mounting.

According to the object of the present invention as described above, the wear protection piece is divided into both sides on the basis of the head block, and a plurality of concave portions and elastic pieces are formed, and the fixed side mold has a rib for preventing the flow of the wear protection piece (Rib) Is formed.

An embodiment of the present invention will be described in detail with reference to FIGS. 3 to 9.

3 is a plan view of a card insertion portion of a card reader equipped with a wear protection piece according to the device of the present invention, and FIGS. 4 and 5 are cross-sectional views, and the wear protection pieces 7 and 7a are bottoms of the card insertion portion 4, respectively. It is provided on the surface and divided into both sides with respect to the head block 6. As shown in FIG.

FIG. 6 is a perspective view of one side wear preventing piece 7 of the divided wear preventing pieces, and the wear preventing piece 7 includes a plurality of cutouts 10 and a plurality of cutouts 10 crossing the wear preventing pieces in the width direction. The single part 11 formed upwardly bent by the ruler formation is formed, and the some recessed part 12 is formed in the both sides of a longitudinal direction.

As shown in FIG. 8, when the wear preventing piece 7 is inserted into the fixed side mold 16, the rib 17 formed in the fixed side mold 16 is inserted into the recess 12 of the wear preventing piece so that the wear preventing piece is left, It prevents the flow in the right direction and another rib 18 of the fixed side mold 16 is inserted into the cutout portion 10 of the wear protection piece to prevent the wear protection piece from flowing upward and downward. The elastic part 11 serves as a handle when inserting the wear protection piece into the mold on the fixed side, and a part thereof is immersed into the card reader body 1 to integrate the wear protection piece and the body.

The wear prevention pieces 7 and 7a installed on both sides of the head block 6 are provided with cutouts, elastic parts, and recesses, and the gaps and sizes are designed in an appropriate number according to the appearance of the card reader. do.

FIG. 7 is a partial perspective view showing the bottom portion of the card insertion portion. The main body 1 has a groove portion 15 formed through the indentation portion 12 and the cutout portion 10 of the wear-prevention piece. It is not necessary to form a separate hole for, and the marking hole 13 (shown by the arrow in the drawing, but may be in other forms) is formed on the card inlet side of the wear protection piece as shown in Figs. A lamp 14 such as an LED is installed at the bottom so that the user can easily know the position of the insertion side of the card and the card moving direction.

By using the device of the present invention configured as described above will be described the operation and effect of the wear prevention piece mounted on the card reader.

First, hold the elastic portion 11 formed on each of the wear preventing pieces 7 and 7a by hand, and insert the wear preventing piece into the insert position formed on the fixing side mold 16, so that each rib 17 formed on the fixing side mold ( 18) is inserted into the recessed part 12 and the cutout 10 formed in the wear protection piece to prevent the wear protection piece from flowing up, down, left and right in the mold.

In such a state, when the movable side mold 19 as shown in FIG. 8 and FIG. 9 is closed and resin is injected, both side portions of the wear preventing pieces 7 and 7a are formed on the bottom of the card insertion portion of the main body 1. It is fixed in one piece and the upper end portion of the elastic part 11 is immersed in the side of the card insertion part and molded in one piece.

After the molding of the main body 1 is completed, the head block 6 is installed between the wear protection pieces 7 and 7a divided from each other, so that the installation or replacement of the head block is easy and the interference of the wear protection pieces is eliminated. Adjustment work becomes easy, too.

As described above, the device of the present invention improves the structure of the wear prevention piece inserted into the card reader and the fixed side mold to prevent the flow of the wear prevention piece during the insert and injection operations, thereby improving the work efficiency and the flow of the wear prevention piece. It is possible to prevent the damage of the mold.

In addition, the elastic portion, which is a part of the wear preventing piece, is immersed in one side of the main body to reinforce the strength of the main body, and the insertion position of the card and the card advance direction are displayed so that the use of the card reader becomes more convenient.
