Abstract

PURPOSE:To contrive the attaining of high speed read/write for a magnetic stripe by increasing the interval of screw threads at a high speed area for the read/write of the magnetic stripe. CONSTITUTION:In the card area of a screw 30 decided corresponding to the size of a card 11, that is, the high speed area H, the thread pitch of a thread 42 is selected to be, e.g., 32mm, and on the other hand, the thread pitch of the thread 42 is decided to be 2.5mm in left/right low speed area L in the high speed area corresponding to the IC read/write part and the loading/ejection part of the card. Thus, the time of the magnetic head 14 reciprocating on the magnetic stripe 13 which was nearly 2sec convertionally is reduced to nearly 1sec. The overrun at stop is decreased by slowing down the moving speed of the magnetic head 14. Further, the low speed area at both ends is utilized and the magnetic head 14 contacts an IC contact onto the card 11 or disconnect it from the card 11.

Description

DETAILED DESCRIPTION OF THE INVENTION [Summary] A screw of a magnetic stripe card reader/writer with an IC is provided with a high-speed area for speeding up the movement of the magnetic head and a low-speed area for reading/writing the IC.

[Industrial application field]

The present invention relates to a magnetic head scanning mechanism, and more specifically, in reading/writing a magnetic stripe card reader/writer with an IC, a magnetic head is moved at high speed when reading/writing a magnetic stripe.
Next, it relates to a mechanism for moving at a low speed to reduce overrun.

[Conventional technology]

The applicant has proposed the magnetic stripe card with IC shown in the plan view of Fig. 2, the front view of Fig. 3, and the rear view of Fig. 4.
A reader/writer has been developed, which consists of a card drive mechanism 19 that inserts an IC magnetic stripe card 11 into a league writer 12, fixes the inserted IC magnetic stripe card 11, and reads the magnetic stripe 13 of the card. , a magnetic stripe read/write mechanism that reads and writes data as the magnetic head 14 is moved by the magnetic head drive device 15; and an IC contact terminal 17 of the IC block 16 in conjunction with the magnetic head drive device 15.
The IC memory read/write mechanism contacts the IC electrode 18 on the IC-equipped magnetic stripe card 13 to read and write data in the IC memory 20, and after the above-mentioned read/write is completed, the IC-attached magnetic stripe card 11
is ejected from the league writer 12 by a card drive mechanism 19.

As shown in FIG. 2, the above-described magnetic stripe card with IC includes a card drive mechanism 19 for inserting the magnetic stripe card 11 with IC into the league writer 12, a magnetic stripe card 11 with IC inserted therein, and a card drive mechanism 19 that fixes the inserted magnetic stripe card 11 with IC. A magnetic stripe read/write mechanism that sequentially reads and writes data by moving a magnetic head 14 over the magnetic stripe 13 of the card by a magnetic head drive device 15; An IC memory read/write mechanism that brings the IC contact terminal 17 of the block 16 into contact with the IC electrode 18 on the IC-attached magnetic stripe card 13 to read and write data in the IC memory 20, and the above-mentioned read/write ends. Thereafter, the IC-equipped magnetic stripe card 11 is ejected from the league writer 12 by a card drive mechanism 19.

This will be explained in more detail according to the order of operation.

The card drive mechanism 19 serves to insert and eject an IC-equipped magnetic stripe card (hereinafter referred to as a card) 11, and also to stop the drive and lock the card during read/write operations. The card drive mechanism 19 of this embodiment is comprised of a switch lever 22, a motor 24, a roller 23, etc. as shown in FIG. 3, but other constructions are also possible.

First, as shown in FIGS. 2 and 3, when the card 11 is inserted into the league writer 12 through the insertion slot 21, the card 11 pushes up the switch lever 22 and the switch turns OFF.
Become N. When the switch is turned on, the motor 24 is rotated, and the roller 23 is rotated in the direction of arrow A via a gear (not shown). This roller 23 uses two rollers arranged above and below the card 11 and rotates to sandwich the card 11, so that when the roller rotates, the card is automatically drawn into the league writer 12. When the drawn card 11 reaches the stopper 25, the switch lever 2
When 6 is pressed, the switch is turned on, the rotation of the motor 24 is stopped, and card insertion is completed.

Next, read/write operations of the card 11 will be explained.

When the card insertion is completed, as shown in FIG. 4, the A sensor 27 confirms that the magnetic head 14 is at this position. After confirmation, the magnetic head 14 is moved over the magnetic stripe 13 by the magnetic head drive device 15 to read and write the magnetic stripe. As shown in FIG. 2, the magnetic head drive device 15 includes a motor 28 and a belt 29.
, a screw 30, a rack 31, etc., but other configurations are also possible.

As shown in FIGS. 2 and 4, the motor 28 is rotated, the rotation is transmitted through the belt 29, and the screw 30 is rotated. The rotational motion of the screw 30 is converted into linear motion by the rack 31, and the magnetic head 1 is moved in the direction of arrow B.
Move 4. By moving the magnetic head 14, the magnetic stripe 13 on the card 11 can be read or written using a signal from the encoder 32. The magnetic head 14 includes a JIS-1 type magnetic head (for the magnetic stripe on the back of the card) and a JIS-n type magnetic head (for the magnetic stripe on the back of the card).
It has both a magnetic head (for the magnetic stripe on the front of the card) and can read and write both types of cards. When the magnetic head 14 touches the B sensor 33, the read/write ends. When the read/write is completed, the motor 28 is reversely rotated to move the magnetic head 14 to the position of the A sensor 27.

In this way, with magnetic stripe read/write, by fixing the card and moving the magnetic head, read/write can be done within the depth of one Habo card, making it possible to downsize the league writer. .

The mechanism shown in FIG. 5 is used to move the magnetic head of the present invention as described above, and the magnetic head 14 is attached to the bracket 4.
3.44 and the screw 41 attached to the plastic bracket 44 is inserted into the groove 42 of the screw as shown in the figure, and when the screw 30 rotates, the bracket 44 moves in the left and right direction as seen in the figure. The structure is as follows.

[Problem that the invention seeks to solve]

In the conventional magnetic head scanning mechanism, f of the screw 30 is
Although the magnetic head was moved by rotating the screw while keeping the intervals of 442 constant, there was a problem that the moving speed of the magnetic head was slow and the processing time was long. For example, it takes about 1 second to move a distance of 10 cm, and 2 seconds to go back and forth on a magnetic stripe.

Attempting to increase the rotation of the screw in order to increase the moving speed increases the size of the motor, which goes against the need for smaller card league writers.

The present invention was created in view of these points, and
In the operation of a card reader/writer with a magnetic stripe, the purpose is to provide a mechanism that can read and write the magnetic stripe at high speed.

[Means for solving problems]

FIG. 1 is a diagram showing the principle of the present invention.

In the present invention, the interval between the grooves 42 of the screw 30 is increased in the high-speed area (card area) for reading and writing the magnetic stripe 13.

[Effect]

Due to the above-described mechanism, the groove spacing is large in the high speed area H, so the magnetic head moves at high speed relative to the same rotation of the screw 30, and in the low speed area L, the groove spacing is small, so the magnetic head moves at a high speed relative to the same rotation of the screw 30. The magnetic head moves at a low speed relative to rotation.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

Referring again to FIG. 1, in the card area of the screw 30, that is, the high speed area H, which is determined according to the dimensions of the card 11, the pitch of the grooves 42 is set to, for example, 32 mm. On the other hand, in the low-speed areas L on the left and right of the high-speed area corresponding to the card insertion/ejection section and the IC read/write section, the groove interval (pitch) of the grooves 42 is set to 2.5.
1. By doing this, the conventional time required of about 2 seconds for the magnetic heald 14 to reciprocate over the magnetic stripe 13 is shortened to about 1 second.

In the low-speed area L, the moving speed of the magnetic head 14 is slowed down to reduce overrun when stopped. It also becomes possible to use the low-speed areas at both ends to bring the IC contact into and out of contact with the card using the magnetic head.

〔Effect of the invention〕

As described above, according to the present invention, when scanning a magnetic head, the time required for scanning a magnetic stripe can be reduced while the motor and the like remain compact.
