However, in the above-mentioned conventional magnetic card reader, a non-conductive synthetic resin material is used for each component for the purpose of weight reduction and easy manufacture. The card transport path along which the magnetic card is transported is also made of a synthetic resin material. Further, since the magnetic card is also made of a synthetic resin material, when the magnetic card is transported in the card transport path, the static electricity charged on the magnetic card stays in the card transport path without being discharged. . The static electricity that has accumulated in the card transport path adversely affects the reading of magnetic data by the magnetic head, causing a read failure. Further, since one side end of the conveyed magnetic card is pressed against the stepped portion of the punch unit by the side force means, the stepped portion is likely to be worn, so that the punching position of the magnetic card is set at the punch pin of the punch unit. However, there was a problem that it was not accurately positioned.

Therefore, the present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to prevent a magnetic data read failure and to always make a punching position by a punch pin accurate. It is to provide a structure of a punch unit in a reader.

m stainless plate is used. When the punch unit 22 configured as described above is attached to the recess 21 of the lower case 2 as described above, the step portion 32 covered by the charge removing member 47 is positioned on the same surface as the inner surface of the side plate 4, and It forms part of 4.

Next, the operation of the magnetic card reader thus constructed will be described. When the magnetic card P is inserted into the card insertion / return port 3, a detector (not shown) detects the card, drives a drive motor (not shown), and the drive roller 16 starts rotating. The rotation of the drive roller 16 causes the drive belt 18 to travel, and the driven belt 20 that is in contact with the drive belt 18 also travels.
It is sandwiched by 20 and conveyed in the card conveying path 6 in the direction of arrow C. When the one end of the magnetic card P to be conveyed abuts the pressing portion 10 of the side force member 8, the magnetic card P is pressed in the direction of arrow A and the other end is pressed against the side plate 4.

Further, when the magnetic card P is conveyed in the C direction and positioned in the punch unit 22, one end of the magnetic card P is pressed against the static elimination member 47 of the step portion 32 forming a part of the side plate 4. Therefore, the static electricity accumulated in the magnetic card P is discharged through the static elimination member 47 formed of a conductive material. Therefore, the magnetic data of the magnetic card P that has passed through the punch unit 22 can be read by the magnetic head 23, but since static electricity which has a bad influence on the reading by the magnetic head 23 has already been removed, the reading is performed accurately. Read failure is prevented.

When the service is completed, the drive belt 18 is conveyed in the opposite direction, whereby the magnetic card P is conveyed in the direction of the arrow D and is again positioned on the magnetic head 23, where the magnetic card P is magnetically moved in accordance with the service. Data is rewritten. The rewritable magnetic card P is punched in the punch unit 22 in response to the rewriting of the magnetic data. That is, the magnetic card P is placed on the punch unit 22.
Is stopped, the coil 27 is excited by the punching signal, and the magnetic flux generated between the lower surface of the fixed core 29 and the upper surface of the movable core 40 causes the movable iron core 35 to attract and rise in the direction of arrow E against the compression coil spring 43. Therefore, the pin portion 36 of the movable iron core 35 rises to form a small hole at one edge of the magnetic card P. When the boring operation is completed, the excitation of the coil 27 is cut off, and the movable iron core 35 is restored to its original position by the compression coil spring 43.

Here, since the static elimination member 47 has excellent wear resistance, the static elimination member 47 is not worn even when the magnetic card P is pressed against the static elimination member 47 and conveyed, so that the pin of the punch unit 22 is pinned. Since the planned punching position of the magnetic card P with respect to the portion 36 is always constant, the punching is always performed at an accurate position. When the punching operation in the punch unit 22 is completed, the magnetic card P is conveyed again in the D direction and returned from the card insertion / return port 3.
