Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application In the present invention, for example, a medium to be conveyed is laterally conveyed to a predetermined position where writing or reading is performed on a medium such as a paper sheet or a card. The present invention relates to such a medium transport device.

(B) Conventional Technology Conventionally, as a medium conveying device provided with the above-described medium width-shifting mechanism, for example, a card is sandwiched and conveyed by a pair of upper and lower conveyor belts installed in the conveying direction, On the side of the regulation plate arranged along the direction, there is a device for aligning the cards by a width-aligning means such as a leaf spring arranged so as to face the regulation plate.

(C) Problems to be Solved by the Invention However, in the medium transporting device configured as described above, since a pair of upper and lower transport belts are installed at fixed transport positions along the transport direction, If the gripping force due to the contact of each conveyor belt is strong, when the conveyed card (medium) is forced to the width of the regulation plate by a leaf spring, etc., the card loses the gripping force of the upper and lower conveyor belts. There is a problem in that it is technically difficult to perform a side-by-side processing of a card such as a paper sheet having a weak material strength because the end portion of the card is bent without being aligned to the regulation plate side.

Further, when the upper and lower conveyor belts are slightly separated from each other to weaken the gripping force, the contact resistance between the upper and lower conveyor belts and the card becomes small, and the card can be surely moved to the width by a leaf spring or the like. On the other hand, since the carrying force of the upper and lower carrying belts is reduced, the cards are temporarily stopped due to contact with leaf springs, etc. Occurs, for example, when writing or reading is performed on a medium such as a magnetic card or an IC card to be conveyed, it causes a jitter defect or the like.

According to the invention, a medium conveying device capable of maintaining both a reliable conveying force and a medium width-shifting function at all times by arranging a conveying means for nipping and conveying a medium in a width-shifting direction. For the purpose of providing.

(D) Means for Solving the Problems In the present invention, a transporting means for sandwiching and transporting a medium, a regulation plate for regulating the transporting position of the medium, and a spacing means for the transporting means are opposed to the regulation plate. A medium conveying device provided at a position for arranging the medium to the regulating plate side, wherein the conveying means is provided so as to be displaceable in the arranging direction, and the conveying means is a material of the medium. It is characterized in that the medium conveying device is provided with an urging means for urging toward the width-shifting means with an urging force weaker than elasticity.

(E) Operation According to the present invention, the medium is clamped and conveyed by the conveying means that moves in the conveying direction, and the conveyed medium is moved to the regulation plate side by the width adjusting means arranged in the middle of the conveyance. In the section where the width-shifting means is acting, the conveying means is displaced toward the regulating plate side in the width-shifting direction against the biasing means, and the medium is conveyed along the regulating plate while being held at a predetermined position. .

(E) Effect of the invention As described above, by the widthwise shifting of the medium by the widthwise shifting means, the conveying means avoids in the lateral shifting direction with a force weaker than the material elasticity of the medium, and the end portion of the medium is bent at the time of lateral shifting. It is possible to prevent the sheet from being conveyed, and to reliably move the medium to the side of the regulation plate to carry it.

Moreover, since the medium is sandwiched and conveyed by the above-mentioned conveying means and the width is integrally moved, there is no change in the clamping force and the conveying force by the above-mentioned conveying means, and each medium to be supplied is at a predetermined position and at a predetermined position. It can be conveyed while being held while holding a space, and stable conveyance can be obtained.
Writing and reading can be performed more accurately with respect to conveyed media such as magnetic cards and IC cards.

In short, since the transporting means for sandwiching and transporting the medium is configured to be movable in the widthwise direction, it is possible to maintain a reliable transporting force,
There is an effect that it is possible to always achieve compatibility with the medium width-shifting function.
