Abstract

PURPOSE:To convey a magnetic card at a fixed speed, and to prevent a read/ write error from generating by conveying the magnetic card in the state of holding between the belts of a first convey part and a second convey part. CONSTITUTION:When the magnetic card is inserted between movable rollers 11 and 21 of convey parts 1 and 2 and movable roller 31 of a convey part 3, the movable rollers 11 and 21 moves to the upward direction resisting leaf springs 15 and 25, and the movable roller 31 moves to the downward resisting a leaf spring 35, then the magnetic card is held between the movable rollers 11 and 21 and the movable roller 31. And when passing the movable rollers 11 and 21 and the movable roller 31 due to the rotation of the convey parts 1 and 2 and the convey part 3, the magnetic card is held between belts 13 and 23 and a belt 33 and conveyed. Since a tension of the belts 13 and 23 from the above is operated, the magnetic card is pushed to a head 40 by a fixed pressure. Thus, it is possible to convey the magnetic card at the fixed convey speed, and to prevent the write error from generating.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a card transport mechanism for transporting the magnetic card, which is provided in a card reading/writing device for reading and writing magnetic cards.

[Prior Art] The structure of a conventional card transport mechanism for transporting this type of magnetic card is shown in 5th rgJ.

This conveyance mechanism has a configuration in which conveyance rollers 52 and 53 are arranged above and below via a conveyance table 51.
The magnetic card 54 is moved on the conveyance table 51 by rotating the magnetic card 54 with the magnetic card 54 sandwiched between them from above and below. Reading and writing are performed by a head 55 located opposite to 51.

[Problems to be Solved by the Invention] However, in the conventional card conveyance mechanism, the magnetic card 54 is conveyed by rubbing on the conveyance table 51, and therefore, due to friction with the conveyance table 51, the conveyance roller 5
There was a problem in that slippage occurred between the magnetic card 54 and the magnetic card 54, and the magnetic card 54 was not conveyed at a constant speed. Furthermore, there is a problem in that reading and writing errors are likely to occur due to such fluctuations in the conveying speed of the magnetic card.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems and provide a card transport mechanism that can transport a magnetic card at a constant transport speed, thereby eliminating the occurrence of writing errors.

[Means for Solving the Problems] The present invention achieves the above object, in a card transport mechanism for transporting the magnetic card, which is provided in a card reading/writing device for reading and writing magnetic cards. A pair of first transport parts and at least one #! arranged between the pair of transport parts. comprising two conveyance sections, each of the conveyance sections being constructed by hanging a belt between rollers that are driven once, one of the rollers of the first conveyance section or the second conveyance section being movable in the vertical direction; A spring means for adding elasticity to the roller is provided, and the second conveyance section is biased in either the vertical direction with respect to the first conveyance section so that the magnetic card can be sandwiched between the first conveyance section and the magnetic card from above and below. It is characterized by having been placed.

The invention as set forth in item 2 is characterized in that each of the rollers of the first @ feeding section and the second conveying section is provided with a plate spring that imparts elasticity in the vertical direction.

[Examples] Examples of the present invention will be described below with reference to the drawings.

FIG. 1 shows an external view of a card transport mechanism according to an embodiment of the present invention, and FIG. 2 shows a side view thereof.

The present card transport mechanism includes a pair of transport sections 1.2 arranged in parallel with a predetermined distance therebetween, and a transport section 3 arranged between the transport sections 1.2.

The conveyance units 1 and 2 are constructed by passing a belt 13.23 between a movable roller 11.21 and a fixed roller 12, 22, respectively, and have the same radius and length. Further, the distance between the transport units 1.2 is slightly smaller than the width of the magnetic card to be transported.

The conveying section 3 includes movable rollers 31. A belt 33 is passed between the fixing parts 32 and is located approximately in the center of the conveying parts 1 and 2. Furthermore, as can be seen from FIG. 2, this conveying section 3 is arranged to be biased downward relative to the conveying section 1.2 so that it can sandwich the magnetic card from above and below together with the conveying section 1.2 as described later. ing.

The transport units 1, 2 and 3 are rotated at the same speed by a drive source (not shown).

Furthermore, the movable rollers 11 and 21 of the conveyance section 1.2 and the movable roller 31 of the conveyance section 3 are respectively movable in the vertical direction, and as shown in the figure, the movable rollers 11 and 21 are elastically applied from above. Additional plate springs 15 and 25 are provided, and the movable roller 31 is provided with a plate spring 35 that adds elasticity from below.

Note that a head 40 for reading and writing magnetic cards is located between the transport section 1 and the transport section 3, or between the transport section 2 and the transport section 3. This head 4o is provided so that its tip is located approximately at the center of the transport section 1.2 and the transport section 3.

Next, the transport operation of the card transport mechanism configured as described above will be explained with reference to FIGS. 3 and 4.

First, the magnetic card 41 is transferred to the transport section l as shown in FIG.
It is inserted from the movable roller 11 side. When the magnetic card 41 is pushed between the movable rollers 11.21 of the conveyance sections 1 and 2 and the movable roller 31 of the conveyance section 3, the movable rollers 11 and 21 move upward against the leaf springs 15.25, and the movable rollers 11.21 move upward against the leaf springs 15.25. roller 3
1 moves downward against the leaf spring 35. This results in
The magnetic card 41 has movable rollers 11 and 21 and movable roller 3.
Sandwiched between 1. When the magnetic card 41 passes through the movable rollers 11 and 21 and the movable roller 31 due to the rotation of the conveyance sections 1.2 and 3, the magnetic card 41 is conveyed so as to be sandwiched between the bell 13.23 and the belt 33. At this time, the movable roller 11.21 and the movable roller 31 are connected to the leaf springs 15, 25.
．． It returns to its original position due to the elasticity of 35.

Further, the magnetic card 41 sandwiched between the belts 13.23 and 33 is pressed against the head 40 with a constant pressure due to the tension applied from above the bells 13.23.

In addition, in the above embodiment, the rollers of both the upper conveyance section 1, 2 and the lower conveyance section 3 were made movable and provided with leaf springs.
Only the rollers of either one of the conveying sections may be used.

[Effects of the Invention] As explained above, according to the card transport mechanism of the present invention,
By transporting the magnetic card with it sandwiched between the belts of the first and second transport sections, there is no friction that previously occurred between the magnetic card and the transport table, so the magnetic card is transported at a constant speed. can be done. This prevents read/write errors from occurring.
