JPS59101029A - Method for adjusting fitting angle of magnetic head and magnetic card reader using this method - Google Patents

Abstract

PURPOSE:To set highly accurately the fitting angle of a magnetic head, by providing a supporting material supported by the 1st fulcrum as a reciprocating- motion possible and turnably and a turning member supported by the 2nd fulcrum as turnably and connecting the supporting material and the turning member with each other so that their movement is simultaneously produced at least at one side of a line connecting both the fulcrums. CONSTITUTION:When the fitting angle of a magnetic head 16 is adjusted, a screw 9 is loosened first so that a head plate 1 and plate 4 can be moved freely. Then an adjusting tool, such as screw driver, is inserted into the space (s) between an angular hole 12 and the left end section 1b of the head plate 1 and the space (s) is expanded or narrowed by utilizing the tapered section of the screw driver and using the width of the space (s) as a standard. Then a dowel 7 turns clockwise or counterclockwise around a fulcrum 5 and, simultaneously, the head plate 1 turns clockwise or counterclockwise with its notched part 1a being moved leftward or rightward through a pin 3. Therefore, as the head plate 1 rotates, the fitting angle of the magnetic head 16 fitted to the head plate 1 is adjusted.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a method for adjusting the angle of attachment of a magnetic head, which improves means for adjusting the angle of attachment of a magnetic head, and a magnetic card reader using the same.

(2) Background of the technology In magnetic card readers, etc., in order to reliably record data on a magnetic card and to read data accurately, the mounting position of the magnetic head must be adjusted relative to the feeding direction of the magnetic card. must be installed with high precision.

However, conventional magnetic head mounting means are unsuitable for mounting magnetic heads with desired precision due to their construction, and there is a need for the development of technical means that can solve this problem.

(3) Prior art and problems In the conventional magnetic card league, for example, when recording on a JIS II type Turret card, the recording angle of the magnetic head is defined by JISB9561 to be within 0°±10 (1st (See Figure 1. In Figure 1, a is a credit card and b is a magnetic stripe.) Conventional means for attaching the magnetic head with precision usually involve a large number of parts and are complicated in construction. Therefore, even if the accuracy of each individual component is made high, if the overall accuracy after adjustment is not high enough, the precision of the magnetic head installation will not be as good. In such a case, not only the accurate recording of data is impaired, but also the read safety factor is lowered due to variations in the output generated by the magnetic head.

(4) Purpose of the Invention The present invention has been devised in view of the above-mentioned drawbacks of the prior art. An object of the present invention is to provide an angle adjustment method and a magnetic card league using the same.

(5) Structure of the invention The first object of the invention is to support a support member to which a magnetic head is attached so that it can reciprocate and rotate around a first fulcrum,
The rotating member is rotatably supported on the second fulcrum, and the supporting member and the rotating member are each moved from a predetermined position between the two fulcrums to at least one side of a line connecting the two fulcrums. Attach the magnetic head by adjusting the angle and fixing the supporting member and the rotating member by causing the movement of the supporting member and the rotating member. The second purpose is to install a magnetic head in a magnetic card league that uses a magnetic head to read the magnetic recording area of a magnetic card. , a rotating member rotatably supported by a second supporting point separated by a predetermined distance from the first supporting point, and the supporting member and the rotating member are connected to a line connecting the two supporting points. This is achieved by configuring the device to be connected to at least one example of the device so as to cause the respective movements to occur simultaneously, and to be fixed by the fixing means after the movement.

(6) Embodiments of the Invention The present invention will now be described in detail with reference to the accompanying drawings.

FIG. 2 is a plan view of a main part of a magnetic card league embodying the present invention, and FIG. 2 is a partial partial view taken along the line m--m in FIG. 1.

In these figures, reference numeral 1 denotes a head plate (supporting member), which is supported reciprocally and rotatably by a stepped pin 3 (first fulcrum) implanted in a block 2. 1a is a notch provided at the right end of the head plate 1 in the drawing. Reference numeral 4 denotes a plate (rotating member), which is rotatably supported by a bin 5 (second fulcrum) that is inserted through the block 2. The first fulcrum and the second fulcrum are preferably on a straight line 6 and separated by a predetermined distance. Then, the head plate l and the plate 4 are partially overlapped, and there is a dowel 7 near the right end of the plate 4 in the figure, and this dowel 7 also has a head corresponding to this dowel 7 in position. A dowel hole 8 is provided at the position of the plate 1. Dowel hole 8
is formed in a shape that allows the dowel 7 to move when the head plate 1 and plate 4 move.

Reference numeral 9 denotes a screw (fixing means) which is inserted into and removed from a female threaded hole 10 formed in the plate 4.

A protrusion 1b is provided at the left end of the head plate 1 in the drawing, and the protrusion 1b is configured to be located within a corresponding square hole 12 cut out in the plate 4.

Further, the head plate 1 is configured to be elastically biased downward by a collar 13, a spring 14, and a screw 15 inserted into and removed from the block 2, so that the stepped portion of the stepped pin 3 is pushed downward. It serves as a stopper for the head plate 1 to be energized.

16 is a magnetic head that is integrated with the head plate 1 by adhesive bonding, 17 is a guide, 18 is a drive roller, and 19 is a card feeding reference surface.

Next, a description will be given of how to adjust the mounting angle of the magnetic head in the magnetic card reader having the above-mentioned main structure.

When adjusting the installation angle of the magnetic head 16, first loosen the screw 9 to allow the head plate 1 and plate 4 to move freely.

Next, insert an adjusting tool such as a screwdriver into the gap S between the square hole 12 and the left end 1b of the head plate 1, and use the tapered part to enlarge or reduce the gap S using the gap S as a guide. bring forth. This allows the dowel 7 to move to the fulcrum 5.
The plate 4 rotates in a clockwise or counterclockwise direction around the center, that is, the plate 4 rotates in that direction. At the same time, the head plate 1 moves through the notch 1a to the left or right through the bin 3, and rotates counterclockwise or clockwise. Therefore, by rotating the head plate l, the mounting angle of the magnetic head 16 mounted thereon can be adjusted. FIG. 4 illustrates this adjustment relationship.

The adjustment of the present invention reduces the number of parts, has a simple adjustment mechanism, and allows fine adjustment, so that highly accurate installation and angle setting can be achieved. Therefore, data can be recorded accurately, and variations in the output of the magnetic head can be reduced to increase the read safety factor.

In the above embodiment, the method of mounting the magnetic head using the gap S as a guide for adjusting the angle is selected as an example, but the method is not limited to this, and the point is that the plate 4
There is no restriction on the structure as long as it is a means that can cause the rotation of the head plate 1 and cause the head plate 1 to rotate while moving in the horizontal direction with respect to the figure.

(7) Effects of the Invention As described above, according to the present invention, (1) The mounting angle of the magnetic head can be set with high precision.

(2) Effects such as a reduction in the number of parts and a simpler configuration can be obtained.
