Abstract

PURPOSE:To miniaturize a device by supporting a reader/writer main body freely oscillatably with energization secured at a reference position and therefore attaining the accurate reading/writing operations without increasing the guide groove length. CONSTITUTION:When the record contents are read by a magnetic head, a guide block 2 is oscillatably supported around a pivot bearing part 8c, i.e., in all directions including X, Y and Z axis directions. If a magnetic card is put obliquely into a guide groove 3, the block 2 oscillates to follow the movement of the magnetic card. Thus the magnetic card stripe part of the card is coincident with the magnetic head with high accuracy. When the scan is through, the block 2 is automatically reset to its original position by the force of an energizing spring 10. In such a way, such a misoperation where the magnetic card is obliquely inserted can be automatically absorbed owing to the block 2 supported oscillatably. Thus the card can be surely read. In such a constitution, the increase of the length is not required for the groove 3 and a device can be miniaturized.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a method for reading recorded information, writing information, or both by manually scanning a magnetic recording medium such as a bank card or a bankbook. Regarding the manual scanning type magnetic recording media reader/writer, we have developed a support structure between the reader/writer main body and the device, which makes it possible to miniaturize the entire device, reduce errors, and improve operability during manual scanning. Regarding improvements.

[Conventional technology]

A manual scanning magnetic recording medium reader/writer manually scans a magnetic card along the slit groove of a guide block equipped with a magnetic head, so that the magnetic head reads recorded information or vice versa. It is a sophisticated device for writing data, and conventionally, for example, Japanese Patent Application Laid-Open No. 1983-31) 6
There is one described in Publication No. 56. This conventional magnetic recording medium reader/writer has a structure shown in FIGS. 3 and 4.

In the figure, 21 is a magnetic recording medium reader/writer fixed on the device 22, and the guide block 23 of this is a flat plate in which a slit-shaped guide groove 23a is formed. A magnetic head 24 is disposed in the middle of the guide groove 23a so as to be movable forward and backward in a direction perpendicular to the guide m23a, and a clock pulse generator 25 is disposed so as to face the magnetic head 24. Note that 25a is a rubber roller that presses the magnetic card 26 against the magnetic head 24.

In order to read information using the conventional device, the lower edge 26b of the magnetic card 26 must be aligned with the bottom surface 23b of the guide groove 23a.
Manually scan in the correct position to make sliding contact. Then, the magnetic strip 26a of the magnetic card 26 passes through the magnetic head 24, and the magnetic head 24 performs a reading operation.

[Problems to be Solved by the Invention] However, the above-mentioned conventional device has the following problems.■ In order to reliably read the information recorded on the magnetic card 26, the magnetic stripe 26a of the magnetic card 26 must be connected to the magnetic head. It is necessary to scan to match the 24 portions with high accuracy. However, since this scanning is performed manually, the magnetic card 26 may be tilted as shown by the two-dot chain line in FIG. 4. To prevent this, it is necessary to lengthen the guide groove 23a. There are limits to the miniaturization of the fruiting device.

■ If the magnetic card is curved, read errors are likely to occur unless the card is read while correcting the bend. In order to correct this deformation and prevent errors, it is necessary to lengthen the guide groove 23a, which becomes an obstacle to miniaturization.

■ It is necessary to manually scan the long guide a23a correctly, that is, linearly along the guide 'a'.
Scanning direction is restricted and operability is poor.

Note that the above problem also applies to writing.

Therefore, the present invention has been made to solve the above-mentioned conventional problems, and there is no need to lengthen the guide groove, the device can be made smaller, and errors can be prevented.
It is an object of the present invention to provide a manual scanning type magnetic recording medium reader/writer that can also improve operability.

[Means for solving problems]

The present invention provides a manual scanning magnetic recording medium reader/writer configured to read recorded information or write predetermined information using the reader/writer main body during manual scanning of the magnetic recording medium. The device is characterized in that it is supported on the device by a swinging mechanism so as to be able to swing freely and biased toward a reference position.

Here, the swing mechanism in the present invention includes, for example, forming a spherical concave guide concave seat on the bottom surface of the reader/writer main body,
A spherical convex supporting convex seat is formed on the upper surface of a pace block fixed to the device, and the concave concave seat is slidably supported by the convex seat,
The Hess Bros. and the reader/writer body are placed in the concave seat,
It can be constructed by connecting the two to be swingable along the convex seat and interposing an unenergized spring between the two to urge the reader/writer main body to the reference position.

Furthermore, the term "magnetic recording medium reader/writer" in the present invention refers to one that reads and/or writes information. A magnetic recording medium is a medium that has a magnetic recording surface on at least a part of the medium, such as a card with a magnetic recording surface on one side, a card with a magnetic stripe, and a bankbook with a magnetic stripe attached. Including etc.

[Effect]

According to the magnetic recording medium reader/writer of the present invention, the reader/writer main body is supported by the swinging mechanism so as to be able to swing freely relative to the device and biased toward the reference position. When scanning is performed diagonally, the reader/writer main body swings to follow this diagonal state. It also oscillates to follow the bending of the magnetic recording medium. Therefore, there is no need to lengthen the guide groove, and the fruiting device can be miniaturized. Further, since the main body swings when manually scanning a magnetic recording medium, the scanning direction is not so restricted, that is, the degree of freedom in the scanning direction is increased, and the operability is improved accordingly.
