Abstract

PURPOSE:To prevent the running edge of a medium from being damaged and to make the operation feeling of an operator smooth and natural by making friction and deformation at the time of running the medium minimum in a manual scan type magnetic reader writer. CONSTITUTION:Rollers 3 and a belt 4 revolved by the rotation of rollers are provided at the bottom part 2 of a magnetic recording medium running groove. Then, the movement and the deformation of the medium is made minimum, the damage of the medium is prevented and the operation feeling is made smooth and natural by allowing the medium to be moved and run by the revolution of the belt 4 while pressing the medium upon the belt 4. When medium running grooves are present on both sides of the medium, the running of the medium is stabilized while slightly pressing the medium toward the side of a magnetic head 5 by forming roller rotation axes of a side opposite to the magnetic head 5 of elastic bodies and making them movable in parallel.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manual scanning type magnetic recording medium reader / writer which is an information processing device.

[0002]

2. Description of the Related Art As shown in FIG. 6, a conventional manual scanning type magnetic recording medium reader / writer has a rubber roller for pressing a magnetic card, which is a magnetic recording medium, against a magnetic head (Japanese Patent Laid-Open No. 63-311656). Issue). In the figure, the magnetic card 6 passes through a narrow running groove between the magnetic head 5 held in the reader / writer body 1 and the rubber roller 30. During the passage, the magnetic card 6 is moved by the magnetic head 5.
The magnetic recording portion is read while being pressed by the rubber roller 30.

[0003]

The purpose of installing the rubber roller in the conventional manual scanning type magnetic recording medium reader / writer is to keep the traveling speed of the magnetic card constant and to support the traveling posture of the medium. In the case of the manual scanning type, there is a problem that the edge of the medium is damaged due to friction between the edge of the medium and the running groove of the reader / writer and forcible pressing.

An object of the present invention is to provide a manual scanning type magnetic recording medium reader / writer which can prevent damage to the edge of a magnetic card.

[0005]

According to the manual scanning type magnetic recording medium reader / writer of the present invention, the medium edge is not pressed against the bottom of the medium running groove for running, but the medium is pressed for moving and running without friction. And a roller for rotating the belt.

Further, according to the present invention, the first and second belts and the first and second belts, which come into contact with the pair of edges parallel to the medium running direction when manually scanning the magnetic recording medium, are provided. First and second rollers that rotate respectively, a first belt,
A manual scanning magnetic recording medium reader / writer including a first roller, a second belt, and means for moving at least one of the second roller in a direction perpendicular to the traveling direction is obtained.

[0007]

An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a side perspective view of a manual scanning type magnetic recording medium reader / writer according to an embodiment of the present invention, and FIG. 2 is A- of FIG.
FIG. In the figure, at the bottom 2 of the magnetic recording medium running groove 1A (FIG. 2) of the reader / writer body 1, five rollers 3 and a belt 4 which is rotated by the rollers 3 (endless) are installed. The roller 3 rotates around the rotating shaft 10 as shown in FIG. Both ends of the rotary shaft 10 are held by bearings 20 such as bearings to allow the roller to rotate. The bearing 20 may be a protrusion that holds the rotating shaft 10 in a direction perpendicular to the shaft. The belt 4 is wound around the outer circumference of the roller 3 and arranged at the bottom of the running groove 1A.

A magnetic recording medium (hereinafter abbreviated as medium) 6 such as a magnetic card is moved and run manually from the left side to the right side in FIG.
The information recorded in (1) is converted (read) into an electric signal, and conversely, the electric signal is magnetized (written) in the magnetic stripe 7. In the moving and running of the medium, normally, the edge 8 of the medium and the bottom 2 of the medium running groove 1A are pressed against each other to cause friction, but in this embodiment, the elastic belt 4 such as rubber is rotated by the roller 3. The medium 6 travels without friction and with minimal deformation due to pressing. Therefore, the operator can realize a much smoother handling sensation than the sensation of hitting the medium while pressing it against the bottom of the traveling groove (metal, hard plastic, etc.). Also, deformation of the medium, peeling of the edge surface,
Wear is minimized.

FIG. 2 is a plan perspective view showing a manual scanning type magnetic recording medium reader / writer according to another embodiment of the present invention. In the figure, in this embodiment, the medium 6 can be horizontally inserted and held in the reader / writer holder 9, and the medium 6 is inserted up to the stop 30.

In the reader / writer holder 9, running grooves for the medium 6 are formed on both sides of an insertion slot for receiving the medium.
Therefore, the rollers 3a and 3b and the belts 4a and 4b are also arranged on both sides of the insertion slot. 5 rollers 3
The a and the belt 4a are arranged in the same state as in the previous embodiment.
However, in order to ensure the easy traveling of the medium 5 while properly maintaining the horizontal positional relationship between the magnetic stripe 7 and the magnetic head 5, the roller 3 arranged near the magnetic head 5 is secured.
a, the roller 3 arranged in the running groove on the side opposite to the belt 4a
b and the belt 4b are moved in parallel in a direction perpendicular to the traveling direction of the medium 6 so that the medium 6 is pressed against the belt 4a side.

FIG. 4 is a plan view showing the structure for holding the roller 3b and the belt 4b, and FIG. 5 is a sectional view taken along line BB of FIG. Between the rotary shaft 10 of the roller 3b and the reader / writer holder 9,
By installing the elastic body 11 such as a spring that presses the rotating shaft 10 toward the opposite roller 3a, the roller 3b and the belt 4b can be moved vertically in the traveling direction of the medium in the traveling plane. Then, the space between the belts 4a and 4b is set to be slightly smaller than the width of the medium 6. Then, when the medium is made to travel, the movable roller 3b and the belt 4b are slightly pushed outward, and the medium 6 is pressed against the belt 4a on the magnetic head side by the stress of the elastic body 11. At this time, the strength of the elastic body 11 is adjusted so that the medium does not buckle.

[0013]

As described above, since the manual scanning type magnetic recording medium reader / writer of the present invention is provided with the roller, the belt and the elastic body for moving the roller in the medium running groove, (1) it occurs during the manual scanning of the medium. Friction and deformation are minimized.

(2) There is almost no damage to the running edge of the medium.

(3) It is not necessary for the operator to press the medium more than necessary or to drive it with force, and the handling feeling is smooth and natural. Has the effect.
