Description

[Detailed Description of the Invention] The present invention relates to a card reader for reading information recorded on an information recording card.

A conventional card reader of this type, for example, a manual scanning type card reader, as shown in FIG.
A magnetic reading head 3 facing in the transverse direction of the scanning groove 1 and a crimping mechanism 4 incorporating a crimping spring for pressing the storage surface of the magnetic recording card A against the magnetic reading head 3 are fixed in the body housing 2. There is.
Therefore, in a card reader having such a structure, the magnetic recording card A is held in the hand and the card is scanned along the scanning groove 1 in the direction of the arrow to read the stored information.

However, with the structure described above, it is possible to scan the magnetic recording card A in the opposite direction to that described above, or to scan from the middle of the scanning groove 1. In the current situation where recording card users perform scanning, reading errors due to scanning errors of the magnetic recording card A are common. According to the above structure, the scanning groove 1
Since the opening 1a is always open to the outside of the aircraft,
Foreign matter, dust, etc. entered the scanning groove 1 through the opening 1a, often causing malfunctions.

The present invention proposes a simple card reader that can prevent scanning errors and foreign objects from entering the scanning groove caused by conventional card readers scanning from the opposite direction or from the middle of scanning. be.

Embodiments of the present invention will now be described in detail with reference to FIGS. 2 and 3.

In FIGS. 2 and 3, the same structural parts as in FIG. 1 are designated by the same reference numerals.

The magnetic reading head 3 and the crimping mechanism 4 are fixed facing each other as shown in FIG. It's on board 5. That is, the base portion 5a of the shutter plate 5 is fixed to the bottom of the body housing 2 with a set screw 6, and the upper side portion 5c bent at right angles from the flexible intermediate portion 5b is connected to the opening 1a of the scanning groove 1. covering the top. A cam surface 7 inclined with respect to the scanning groove 1 is formed at the front end of the upper side 5c in the scanning direction of the magnetic recording card.

Therefore, when the magnetic recording card A is inserted into the scanning groove 1 from the direction of the arrow, the front edge of the card hits the cam surface 7 and the shutter plate 5 is bent as shown by the phantom line in FIG. The magnetic recording card A can be moved along the groove 1 and scanned by the magnetic head 3.
In this case, even if you try to insert the magnetic recording card A from the middle of the scanning groove 1 or from the opposite direction, the upper side 5c of the shutter plate 5 will become distorted because the cam surface 7 is not formed halfway or from the opposite direction. , the magnetic recording card A cannot be inserted into the scanning groove 1. Also,
When the magnetic recording card A is not scanned, the upper side of the opening 1a of the scanning groove 1 is covered by the upper side 5c of the shutter plate 5, so that foreign objects etc. do not fall into the scanning groove 1.

In the above embodiments, a magnetic card reader was used as an example, but it is obvious that the present invention can also be applied to an optical reading type card reader. Further, although an example has been shown in which the shutter plate 5 is formed separately from the fuselage housing 2, the shutter plate 5 is not limited to this.
Furthermore, it may be configured to be provided at the inner top part of the fuselage housing 2 to achieve the same purpose.

As is clear from the above explanation, according to the present invention, the scanning direction of the information recording card is limited only by the addition of the shutter plate, so scanning errors due to scanning in the reverse direction or from midway through, and dust in the scanning groove can be avoided. , it is possible to eliminate malfunctions caused by the intrusion of foreign objects.
