Description

[Detailed description of the invention] The present invention relates to a card reader with a dustproof cover, which opens the cover when a card comes into contact with the cover, and closes the cover when the card leaves the cover. be.

A conventional card reader includes a pair of guides 2 and 3 for guiding the card 1 in the direction of arrow A, and a card 1 as shown in FIG.
It has a magnetic head 4 for recording and reproducing information on the card, and a pressing plate 5 for pressing the card 1 against the magnetic head 4. Some models were also provided with dustproof covers 6, 7 as necessary to prevent dirt, dust, etc. from entering from the outside. However, although the dustproof covers 6, 7 surround the guides 2, 3, the magnetic head 4, etc., the card 1 transport path 8 formed between the guides 2 and 3 is protected against intrusion of dirt, dust, etc. was not prevented. This is because if the transport path 8 is covered with a cover, it becomes impossible to insert the card 1, and the card reader no longer functions. For this reason, the conventional card reader shown in FIG. 1 cannot completely prevent the intrusion of dirt, dust, etc. If it adheres to the sliding surface of the magnetic card 1, it may damage the card 1 or wear out the magnetic head 4, and furthermore, errors may occur when information is written to or read from the magnetic card 1.

The present invention provides a card reader that eliminates the above-mentioned drawbacks, and the present invention will be explained below with reference to the drawings. FIG. 2 is a perspective view of the magnetic card reader with a dustproof cover of the present invention. In FIG. 2, when the magnetic card 1 (hereinafter referred to as card) is moved in the direction of arrow B and inserted from the insertion section 9,
The leading end of the card 1 in the advancing direction opens the dustproof covers 10 and 11 (hereinafter referred to as covers) that are in contact with each other to allow the card 1 to pass through.

FIG. 3 is a plan view of FIG. 2, looking in the direction of arrow C. In FIG. 3, the covers 10 and 11 are in an open state due to the insertion of the card 1. Inside the cover 10 is a magnetic head 14 (hereinafter referred to as head) attached to a guide 12, and inside the cover 11 is a press plate 15 attached to a guide 13. Therefore, when the card 1 is moved in the direction of arrow A, the head 14 reads or writes information to the card 1. Here, as mentioned above, insert the card 1 through the opening 9 using the arrow A.
When the card 1 is inserted in this direction, it is the cover 11 that moves according to the thickness of the card 1 (in the vertical direction in the figure). Space 1 formed between cover 11 and guide 13
6a and 16b are provided with a mechanism for moving the cover 11 when the cover 11 and the card 1 come into contact with each other.

FIG. 4 shows a part 11 of the cover 11 in FIG.
It is a front view when seen from the direction of arrow B with a (shaded area) removed, and shows a mechanism for moving the cover 11 described above. In FIG. 4, one end of the lever 17 is rotatably provided with shafts 18 and 19, and the other end of the shaft 18 is attached to the cover 1.
1, and the other end of the shaft 19 is attached to the guide 13. A coil spring 20 is wound around the shaft 19, one end 20a of the coil spring 20 is supported by the lever 17, and the other end 20b is supported by a part of the guide 13. Therefore, the lever 17 is biased so as to rotate in the direction of arrow D about the shaft 19. In the configuration described above, the card 1 is connected to the cover 11
When opened in the direction of arrow E, the shaft 18 fixed to the cover 11 moves the lever 17 against the bias of the coil spring 20. When the card 1 is removed, the lever 17 is energized by the coil spring 20.
moves in the direction of the arrow D, the cover 11 also returns in the direction of the arrow D via the shaft 18 provided on the lever 17. Therefore, the cover 11 and the cover 10 come into contact with each other to prevent dirt and dust from entering the device. In this way, the card reader with a dustproof cover of the present invention can completely prevent dirt and dust from entering by moving the cover, which reduces reading errors of the card reader and further extends the life of the device. I can do that.
