Abstract

PURPOSE:To enable uniform and certain imprinting, by providing a spring for contacting an imprint roller, which is movably attached in the direction vertical to the support mechanism moving to a horizontal direction by a drive part, to the surface of a magnetic card under pressure in the vertical direction. CONSTITUTION:When paper 7 and a magnetic card 5 are fed to a predetermined position, a support mechanism 2 moves to the other end side and a roller 26 rolls along the central part of a guide rail 27 and, therefore, an imprint roller 3 is lowered against the elastic force of a tensile spring 23 and contacted with the surface of the magnetic card 5 under pressure through the paper 7. In this case, because the imprint roller 3 is contacted with the surface of the magnetic card 5 in a vertical direction by the elastic force of a spring 4, the pressing force of the imprint roller 3 to the surface of the magnetic card 5 can be uniformized. Furthermore, because the imprint roller 3 moves to the vertical direction with respect to the support mechanism 2, uniform imprinting can be performed even if irregularity in up and down positions is generated when the magnetic card 5 is imprinted.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an imprint device, and more particularly to an imprint device that imprints characters on a magnetic card used in an automatic teller machine or the like using an imprint roller. .

[Background of the invention]

In a conventional imprint apparatus of this type, as shown in FIGS. 5 and 6, for example, a drive screw a is rotatably mounted, and a support block b is engaged with the drive screw a. A support d is rotatably attached to the lower part of the support 2-page block b via one fulcrum shaft C. A tension spring 6 is interposed between the upper part of the support d and the upper part of the support flock b. Further, at the lower part of the support d, there is a central axis f.
Imprint roller g is attached by
Guide rollers h, h are pivotally attached to both ends of the central axis f, respectively.

On the other hand, a rail 1 that guides guide rollers h, h is mounted, and the guide rail i has a high-pressure part j made of a thick plate at both ends thereof, and a low-pressure part j made of a thin plate in the center thereof. A local portion k is formed respectively. t is paper and m is a magnetic card.

In the imprint apparatus, when a magnetic card m and paper t are set, when a drive screw a is rotated, a support block b is moved in the axial direction, and a guide roller h is moved to a high part j of a guide rail 1. guided upwards to the lower part. At this time, a gap is created between the lower part of the guide rail l and the guide roller h, so the imprint roller g presses the paper and the three-page magnetic card m by the elastic force of the tension spring e. Therefore, the structure is such that characters can be imprinted on the embossing (not shown) of the magnetic card m.

Further, the imprint apparatus illustrated in FIG. 7 has a drive shaft n
A disk 0 is fixed to , and a second link q is connected between the disk 0 and the intermediate portion of the first link p. One end of the first link p is pivotally connected to the fixed shaft r, and the intermediate portion of the support body d is pivotally connected to the other end by a fulcrum shaft C. The support d has one end connected to the other end of a tension spring t whose one end is connected to the pin 3, and an imprint roller g attached to the other end by a central axis f.

Note that in FIG. 7, the same reference numerals as those in FIGS. 5 and 6 represent the same things, so a description thereof will be omitted here.

In this imprint apparatus, when the disk 0 is rotated by driving the drive shaft n, the first link p is swung about the fixed shaft r via the second link q, so that the support d is moved around the guide roller h. The imprint roller g is moved from the high part j of the idle rail l to the low part k.
However, by pressing the magnetic card m through the paper t against the elastic force of the tension spring t, the magnetic card m can be imprinted.

By the way, in general, when imprinting on a magnetic card, no matter which direction the imprint roller is moved,
In order to ensure reliable imprinting, it is desirable that the pressing force of the imprint roller be applied perpendicularly to the surface of the magnetic card.

However, in the two conventional examples shown above, the central axis f for attaching the imprint roller g and the fulcrum axis C for supporting the support body d do not coincide with each other on a vertical line. Depending on the direction in which the print roller g travels, a deviation may occur in the pressing force. That is, as shown in FIG. 5, when the imprint roller g is rotationally moved in the right direction A by the movement of the support block b and the support body d, the tension force of the tension spring e is applied to the support body d. Since a force acting in the direction is applied, the pressing force of the imprint roller g is weakened. Further, when the imprint roller g is rotated to the left to the left, a force acting in the opposite direction to the tension of the tension spring e is applied to the support body d, so that the pressing force of the imprint roller g is further strengthened.

Note that the same applies to the conventional example shown in FIG.

Therefore, since the pressing force differs depending on the moving direction of the imprint roller g, there is a problem that the characters imprinted on the magnetic card m vary.

[Purpose of the invention]

In view of the above circumstances, the present invention has an object to uniformly and reliably imprint a magnetic card regardless of the moving direction of an imprint roller, thereby reliably preventing variations in imprint characters. The purpose of this invention is to provide an imprint device that can perform the following steps.

The support block 21 has a female thread passing through its side and engaging with a male thread of the drive part 1. The slide guide 22 is formed in a substantially U-shape by an upper plate 22a fixed to the bottom of the support block 21 and outer plates 22b hanging down from both ends of the upper plate 22a. The support body 24 is a top plate 24
a, and an inner plate 24 hanging from both ends of the top plate 24a.
It forms a U-shape with b.

Then, the support body 24 is inserted inside the slide guide 22, and the tension spring 2
3, the support body U is biased against the slide guide 22 by the elastic force of the tension spring 230.

In that case, a support protrusion 24a is provided on the inner plate 24b of the support body, and a long hole 22o is formed in the outer plate 22b of the slide guide along the vertical direction, and the support protrusion 24a is formed in the outer plate 22b of the slide guide. 24a is engaged and the elongated hole 22a guides the support protrusion 24a, so that the support body 24 can be moved in a direction perpendicular to the slide guide 22.

On the other hand, the roller 26 has support inner plates 24b, 2
They are attached to both ends of a central shaft 25 inserted through the lower part of the shaft 4b. The guide rail 27 has a shape in which the center part of the bottom surface bulges downward from both ends, and is arranged horizontally, and the elastic force of the tension spring 23 causes each support member to move toward the slide guide 22. By being biased, the row 226 can be guided on the bottom surface thereof.

The support mechanism 2 rotates the drive unit 1 to rotate the support block 2 along the axial direction of the drive unit 1.

The imprint row 23 imprints the magnetic card 5 conveyed to a desired position, and the imprint row 23 imprints the magnetic card 5 conveyed to a desired position. It has a larger diameter than the roller 26, and is made of, for example, a molded product of metal, rubber, or the like. This imprint roller 3 is attached to the central shaft 25 and is attached to the inward side plate 2 of the support body 24.

Note that 7 is paper.

Next, the operation of the imprint apparatus configured as described above will be described.

When the page support mechanism 2 is located beside one end of the drive unit 1,
That is, when the roller 26 is located at one end of the guide rail 27, the bottom surface of the one end is higher than the center, so even if the elastic force of the spring 4 is applied, the imprint is not affected by this. The roller 3 is now lifted above the position of the fifth surface of the magnetic card.

At this time, when the paper 7 and the magnetic card 5 are conveyed to a predetermined position, the support mechanism 2 is moved toward the other end by the drive unit 1, and the roller 26 is moved toward the guide rail 27.
, the imprint roller 3 presses against the surface of the magnetic card 5 through the lower paper 7 against the elastic force of the tension spring 23.

At this time, the imprint roller 3 is pressed perpendicularly to the 5 surface of the magnetic card by the elastic force of the spring 4, so that the pressing force of the imprint roller 3 against the 5 surface of the magnetic card can be made uniform. . Moreover, since the imprint roller 3 moves perpendicularly to the support mechanism 2, even if there are variations in the vertical position when the magnetic card 5 is imprinted, this will not affect the Can be imprinted uniformly. Therefore, the imprint roller 3 can clearly imprint characters and the like on the surface of the magnetic card 5 even if it moves in either the left or right direction.
