Abstract

PURPOSE:To provide a magnetic card reader which can be exactly and stably operated at a low cost. CONSTITUTION:This device is equipped with card guides 3 and 9 which allows a magnetic card 1 to straightly travel, card holder 4 which receives the short side edge of the magnetic card 1, spring 5 connected with the card holder 4, which expands according to the movement of the card holder 4, magnetic head 6 which reads the magnetic data of the magnetic card 1, and constant speed roller 7 arranged so as to be opposed to the magnetic head 6 so that the magnetic head 6 can be brought into contact with the magnetic card 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic card reader.

[0002]

2. Description of the Related Art In a conventional magnetic card reader, a motor-driven type in which a magnetic card is sandwiched and slid by a motor-driven roller as a means for sliding a magnetic stripe of the magnetic card is arranged on the magnetic head. It is either a manual type that is manually slid along the groove.

[0003]

Among the above-mentioned conventional magnetic card readers, the motor drive type is expensive because it requires a motor and a power source for the motor, and the manual type is less expensive than the motor drive type. However, since it is left to humans to perform arbitrary operations, the sliding speed with respect to the magnetic head is unstable, and it may not be possible to slide the magnetic stripe from the leading edge to the trailing edge reliably, resulting in a read error. There is a problem that there are many.

An object of the present invention is to provide a magnetic card reader which is inexpensive and whose operation is reliable and stable.

[0005]

A magnetic card reader according to the present invention comprises a card guide for running a magnetic card in a straight line, a card holder for receiving a short side edge of the magnetic card, and a card holder connected to the card holder. A spring that expands and contracts due to the movement of the card holder, a magnetic head that reads the magnetic data of the magnetic card, and a constant speed roller that is arranged facing the magnetic head so that the magnetic card contacts the magnetic head are provided. It is configured.

[0006]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1A is a front view showing an embodiment of the magnetic card reading apparatus of the present invention, and FIG. 1B is a left side view thereof. In FIG. The guide 9 is omitted.

Card guides 3 and 9 are magnetic cards 1.
Are fixed to a frame (not shown) at regular intervals so that they can move smoothly.

A magnetic head 6 and a constant speed roller 7 which rotates at a constant speed by the air resistance of the vane plate 10 are arranged so as to face the passage position of the magnetic stripe 2 on the magnetic card 1 and are fixed to the frame. There is.

One end of a spring 5 is connected to a card holder 4 which receives the lower end of the magnetic card 1, and the initial state is at the upper part. The other end of the spring 5 is fixed to the frame.

The holder stopper 8 is a mechanism for temporarily holding the approaching card holder 4 when the magnetic card 1 is inserted and pushed in. The fulcrum 11 is fixed to the frame.

Next, the operation of this embodiment will be described with reference to FIGS. 1 (a) and 1 (b).

When the magnetic card 1 is inserted into the grooves of the card guides 3 and 9 and pushed downward in FIG. 1, the spring 5 is compressed and energy is stored.

When the magnetic card 1 is pushed further in, the card holder 4 pushes the holder stopper 8 away, and then the card stopper 4 is fitted. Even if the hand pushing the magnetic card 1 is released, the magnetic card 1 is not ejected.

In this state, when the lower end of the holder stopper 8 is pushed to the left by a finger or the like, the fitting is released and the spring 5 extends, so that the magnetic card 1 moves upward together with the card holder 4. By this movement, the magnetic information of the magnetic stripe 2 is read by the magnetic head 6.

If the moving speed at this time is too fast, there is a risk that the reading control device (not shown) will not be able to receive information in time, or the magnetic card 1 may pop out. A vane plate 10 is attached to the constant velocity roller 7 that presses the magnetic card 1 against the head 6, and due to the air resistance to the vane plate 10, the vane plate 10 moves at an appropriate speed without excessively high speed.

[0017]

As described above, the magnetic card reader according to the present invention utilizes the restoring force of the spring and uses the constant speed roller, so that the operation is sure and stable and the economy can be remarkably improved. have.
