Abstract

PURPOSE:To improve the follow-up performance of a magnetic card to a curved magnetic card and to improve the reliability of data recording/reproducing by forming a plate spring for pressing a magnetic head supporting plate to a magnetic card reader body side on a line connecting respective pins. CONSTITUTION:When the magnetic card 18 is inserted into a card sliding surface of the magnetic card reader body 11, the magnetic stripe of the magnetic head 18 is allowed to contact with the magnetic head 13 and data are recorded/ reproduced in/from the magnetic stripe. At that time, the magnetic head 13 is pressed by the elasticity of the plate spring 16 and the contact of the magnetic head 13 with the magnetic stripe is improved. Since the line connecting the pins 14, 15 is pressed by the plate spring 16, the magnetic head supporting plate 12 is smoothly rotated in the right and left direction around said line, so that the magnetic head 13 can precisely follow up the magnetic card even if the card is curved.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is directed to a magnetic head support II of a magnetic card reader for reading magnetic cards such as bank cash cards and credit cards. This is about i-taka.

2. Description of the Related Art A conventional magnetic head support device of this type of electric card reader is constructed as shown in FIGS. 3 and 4. In the figure, 1 is a magnetic card reader main body having a magnetic card sliding surface. 2 is a magnetic head support plate to which the magnetic head 3 is attached; 4.5 is a pin provided on the magnetic head support plate 2 for positioning and supporting the magnetic head support plate 2 on the magnetic card reader main body 1; Numeral 6 is a screw for attaching the magnetic head support plate 2 to the magnetic card reader main body 1 together with the flat washer 7 and the coil spring 8. 9 is a magnetic card.

The operation of the magnetic head support V device configured as described above will be described below. When the magnetic card 9 is inserted into the card sliding surface of the magnetic card reader main body 1, the magnetic stripe of the magnetic card 9 comes into contact with the magnetic head 3, and data is recorded on and reproduced from the magnetic stripe. At this time, the elasticity of the coil spring 8 applies pressure to the magnetic head 3 to improve contact with the magnetic stripe. Also, pin 4,
The magnetic head support plate 2 rotates left and right around the line connecting the points 5 and 3, causing the magnetic head 3 to follow even a warped magnetic card.

Problems to be Solved by the Invention In such a conventional configuration, the magnetic head support plate 2 is pushed by the coil spring 8, but the left and right rotation of the magnetic head support plate 2 about the line connecting the pins 4 and 5 is prevented. There is a problem in that the movement is not smooth because the coil spring 8 presses a part other than the center, and the magnetic head does not completely follow the magnetic card.

The present invention is intended to solve these problems, and aims to improve the tracking of a magnetic head against a warped magnetic card and improve the reliability of data recording and reproduction. .

Means for Solving the Problem In order to solve this problem, the present invention provides a pin that is penetrated and fixed at least in the vicinity of both ends of a magnetic head support plate that fixedly supports a magnetic head, and this pin is connected to a magnetic card reader. A leaf spring is provided which is brought into contact with the main body and pushes the magnetic head support plate toward the magnetic card reader main body on a line connecting the pins, so that the magnetic stripe of the magnetic card can come into contact with the magnetic head. be.

Function: With this configuration, the magnetic head support plate can easily move left and right around the line connecting the pins, and the magnetic head can better follow the magnetic card.

Examples Hereinafter, two 17i examples of the present invention will be described with reference to the drawings (Fig. 1,
The explanation will be based on Fig. 2).

In the figure, 11 is a magnetic card reader main body having a magnetic card sliding surface. Reference numeral 12 denotes a magnetic head support plate on which the magnetic head 13 is attached with adhesive or the like; 14 and 15 are fixedly provided through the vicinity of both ends of the magnetic head support plate 12 in order to position and support the magnetic head support slope 12; With a pin,
Its tip abuts on the magnetic card reader main body 11. The pins 14 and 15 are located at the center of the magnetic head support plate 12 in the width direction. Reference numeral 16 is a leaf spring that presses the magnetic head support plate 12 between the pins 14 and 15, and is attached by a screw 1γ screwed into the magnetic card league main body 11. 18 is a magnetic card. Incidentally, the magnetic head support plate 12 is constructed so as not to have elasticity. Moreover, the machine spring 1
6 is the screw 17 on the line connecting the two pins 14 and 15.
The magnetic head support plate 12 is pushed toward the magnetic card reader main body 11 on both sides.

Regarding the magnetic head support device configured as described above,
The operation will be explained below. When the magnetic card 18 is inserted into the card sliding surface of the magnetic card reader main body 11, the magnetic stripe of the magnetic card 18 comes into contact with the magnetic head 13, and data is recorded and reproduced from the magnetic stripe. At this time, due to the elasticity of the leaf spring 16, the magnetic head 13
Apply pressure to make good contact with the magnetic stripe. or,
By pushing the line connecting the pins 14 and 15 with the leaf spring 16, the magnetic head support plate 12 smoothly rotates left and right about this line, and even if the magnetic card is warped, the magnetic head 13
can be followed well.

Effects of the Invention As described above, according to the present invention, the spring that presses the magnetic head support plate is changed from a coil spring to a leaf spring, and the left and right sides of the magnetic head support plate are moved by pressing on the line connecting the pins of the magnetic head support plate. It has great practical effects by improving the rotation of the magnetic card, improving the tracking of the magnetic head against warped magnetic cards, and improving the reliability of data recording and reproduction.
