Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic card reader / writer for inputting / outputting magnetic information to / from a magnetic card.

[0002]

2. Description of the Related Art A magnetic card reader / writer for inputting / outputting magnetic information to / from a magnetic card such as a financial card or a credit card is provided with a magnetic card inserted by a customer through an insertion opening of the main body inside the main body. Magnetic information is input and output by a magnetic head provided on the conveying path while being conveyed by rollers. The conventional magnetic card reader / writer will be described below.

FIG. 3 is a side view showing an internal structure of a conventional magnetic card reader / writer, and FIG. 4 is a side view of rollers of the magnetic card reader / writer. Reference numeral 1 denotes a magnetic card, which is inserted into the main body 2 through an insertion opening 3 formed in the front surface of the main body 2. Inside the main body portion 2, a pair of upper and lower first drive rollers 4a for conveying the magnetic card 1, a first driven roller 4b, a second drive roller 5a, a second driven roller 5b, and a third driven roller 5b. Drive roller 6a, third driven roller 6
b is provided. Reference numeral 7 denotes a motor, which rotates the first drive roller 4a, the second drive roller 5a, and the third drive roller 6a by a transmission unit (not shown) such as a gear, a pulley, or a belt.

The magnetic card 1 is provided in the transport path of the magnetic card 1.
Magnetic heads 8 and 9 are provided for reading the magnetic information recorded in and writing the magnetic information. A plurality of optical sensors 10, 11, 12, 13 for detecting the magnetic card 1 are provided inside the main body 2. The detection signals of these sensors 10, 11, 12, 13 are used for magnetic card insertion, magnetic card removal, determination of input / output start / end positions to the magnetic card 1, and the like.

In FIG. 4, the first drive roller 4a is mounted on the rotary shaft 14. Also, the first drive roller 4a
A rib 15 is projected on the end face of the rotary shaft 14
A pin 16 is attached to the pin. Therefore, the first drive roller 4a can freely rotate about 180 °.

This conventional magnetic card reader / writer is constructed as described above, and its handling operation will be described below. In FIG. 3, when the customer inserts the magnetic card 1 from the insertion slot 3, the sensor 10 detects it, the motor 7 is driven, the first drive roller 4a starts the forward rotation, and the magnetic card 1 of the main body 2 is moved. It is drawn inside and conveyed to the right.
Then, when passing through the magnetic heads 8 and 9, necessary magnetic information is input and output. Next, the magnetic card 1 is the main body 2
After being conveyed to the inner part of the, the motor 7 drives in the reverse direction,
The magnetic card 1 is conveyed toward the insertion slot 3 and is stopped while being vertically held by the first drive roller 4a and the first driven roller 4b as shown in FIG. Therefore, the customer holds the left end of the magnetic card 1 and pulls it out of the main body 2.

[0007]

However, in the above-mentioned conventional structure, since the first drive roller 4a is structured to freely rotate 180 °, when the magnetic card 1 is stopped at the position shown in FIG. There is a problem that the magnetic card 1 is easily detached from the first drive roller 4a or jumped out of the main body portion 2 due to the inertia of conveyance in the direction.

Further, in order to pull out the magnetic card 1 from the main body 2 because the first drive roller 4a idles about 180 °, it is necessary to increase the diameter of the first drive roller 4a. There was a problem that it became quite large.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a magnetic card reader / writer which solves the above-mentioned problems of the conventional example and can easily pull out a magnetic card from a main body.

[0010]

Therefore, according to the present invention, an output is generated when a customer pulls out a magnetic card that is held by being held by a pair of upper and lower rollers provided near the insertion opening of the main body. A magnetic head is provided between the insertion slot and the roller, and the roller is driven and rotated based on the output to eject the magnetic card from the insertion slot.

[0011]

In the above structure, when the customer pulls out the magnetic card, the magnetic head outputs magnetic information such as the magnetic stripe of the magnetic card, which drives the motor to rotate the roller and convey the magnetic card in the ejection direction. To do.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will now be described with reference to the drawings. FIG. 1 is a side view showing the internal structure of a magnetic card reader / writer according to an embodiment of the present invention, and FIG. 2 is a plan view of the magnetic card. In FIG. 1, the same parts as those in the conventional example shown in FIG. In FIG. 1, a magnetic head 17 is provided between the insertion slot 3 and the first drive roller 4a. The magnetic head 17 outputs magnetic information of the magnetic stripe 18 of the magnetic card 1 shown in FIG. By this output, the motor 7
Is driven, and the first drive roller 4a rotates in the direction of ejecting the magnetic card 1 from the main body 2.

In the above structure, when the customer inserts the magnetic card 1 through the insertion slot 3, the sensor 10 detects it, the motor 7 is driven, and the first drive roller 4a starts forward rotation.
The magnetic card 1 is drawn into the main body 2 and conveyed rightward. Then, when passing through the magnetic heads 8 and 9, necessary magnetic information is input and output. Then magnetic card 1
Is conveyed to the inner part of the main body 2, the motor 7 is driven in the opposite direction, and the magnetic card 1 is conveyed toward the insertion slot 3.
As shown in FIG. 1, the first driving roller 4a and the first driven roller 4b are stopped while being sandwiched from above and below. Therefore, the customer holds the left end of the magnetic card 1 and pulls it out of the main body 2. Then, the magnetic head 17 outputs the magnetic information of the magnetic stripe 18 of the magnetic card 1, whereby the motor 7
Is driven, the first drive roller 4a rotates in the direction of ejecting the magnetic card 1 from the main body 2, and the magnetic card 1 is ejected. The motor 7 is stopped by using the detection of the completion of pulling out the magnetic card 1 by the sensor 10 or by setting the drive time of the motor 7 in advance.
If the customer does not pull out the magnetic card 1 within the set time, the motor 7 may be driven in the insertion direction so that the magnetic card 1 is taken into the main body 2.

[0014]

As described above, according to the present invention, the customer can easily pull out the magnetic card from the main body. Further, since it is not necessary to increase the diameter of the roller, the overall outer shape can be reduced.
