Abstract

PURPOSE:To properly deliver cards one by one even when two cards strongly adhere to each other by forming a step on a feed roller along a direction orthogonal with a rotating direction and, then, positioning the upper surface of the feed roller lower than the upper surface of an idle roller. CONSTITUTION:A stepped roller 3C has a step 3C' all around and the upper surface of a pair of rollers 3a and 3b forming a feed roller 3 is positioned lower than the upper surface of idle rollers 2a and 2b by the prescribed distance. When two cards C1 and C2 firmly adhere to each other, the lower card C1 only flexes a single friction plate 4a and, therefore, can easily move toward an auxiliary feed roller 5. The upper card C2, however, must flex two friction plates 4a and 4b and, therefore, the travel thereof is blocked at the positions of the plates 4a and 4b. Thus, only the card C1 is separated at the positions and delivered.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card feeding device incorporated in an encoder for writing predetermined magnetic data on a so-called raw card on which magnetic data is not recorded.

[0002]

2. Description of the Related Art Conventionally, in order to write magnetic data to a raw card which is stacked in a card stocker (hereinafter, referred to as a stocker), a feed roller is provided below the stocker and stacked on the feed roller. The card in this state is placed and the feed roller thereof is rotated so that the card is delivered one by one to the data recording unit having the magnetic head.

[0003]

However, in the above-mentioned conventional apparatus, a feeding error may occur in which the cards are fed in a stacked state.

The cause of the feeding error is when the two cards are in close contact with each other. When a feeding error occurs, the data recording unit cannot write data and the encoder stops abnormally. . In this case, a staff member inspects each time to eliminate the jam.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a card feeding device that can reliably feed one card at a time even if two cards are in a strong contact state.

[0006]

In order to achieve the above-mentioned object, a card feeding device according to the present invention is provided with a feed roller on the card feeding side of the lower part of the stocker and an idling roller on the opposite side thereof. In a card feeding device that puts a card in the stocker by a roller and rotationally drives the feed roller in a card feeding direction to feed a card from the stocker, the feed roller is orthogonal to the rotation direction. It is characterized in that a step is provided in the direction in which the upper surface of the feed roller is located below the upper surface of the idle roller. Also, on the outlet side of the stocker,
The stocker has a predetermined distance from the discharge port, the lower side is located slightly below the position of the discharge port, is parallel to the longitudinal direction of the discharge port, and the plate surface is the wall surface of the stocker on the discharge port side. Parallel to, and the lower end position on the wall surface side is positioned higher than the other lower end position by the thickness of one card.
It is characterized in that a friction plate made of a flexible sheet is provided. An auxiliary feed roller, which has a predetermined distance from the discharge port, is mounted on the discharge port side of the stocker, and which is fed from the discharge port and is rotationally driven in the feeding direction of the card is provided. At the same time, a roller with a torque limiter is provided above the auxiliary feed roller and with a gap having a thickness of one card.

[0007]

In the above structure, the feed roller vertically moves the ejection port side of the stacked cards and moves the lowermost card to the ejection port side.

The friction plate sends only the lowermost one card to the data writing unit side when two or more cards are stacked and ejected from the ejection port.

The auxiliary feed roller and the roller with the torque limiter send only the lowermost one card to the data writing section side when two or more cards are stacked and discharged from the discharge port.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a vertical sectional view of an apparatus according to an embodiment, and FIG. 2 is a plan view of FIG. 1, in which an idle roller 2 and a feed roller 3 are provided below a well-known stocker 1 having an open upper portion and a lower portion.
And are provided.

The idle roller 2 includes a pair of rollers 2a and 2a.
b, a direction that is provided on the opposite side to the discharge port 1b provided at the lower end of one wall surface (right wall surface in the illustrated example) 1a of the stocker 1 and that is orthogonal to the longitudinal direction of the discharge port 1b. It is provided so that it can freely rotate, that is, the card C stored in the stocker 1 can freely rotate in the direction in which it is fed out from the discharge port 1b.

The feed roller 3 includes the rollers 2a and 2
b, a pair of rollers 3a, 3b provided in a position facing the rollers 2a, 2b and rotating in the same direction, and a stepped roller 3c positioned between the rollers 3a, 3b.
Are fixed to a rotation shaft M ′ that is rotationally driven by a motor M, and are provided on the discharge port 1b side.

The pair of rollers 3a and 3b are rollers of the same diameter, and the stepped roller 3c is a pair of rollers 3a and 3b.
3b, which has a diameter slightly smaller than the diameter of the roller 3a. There is provided a protrusion slightly protruding from the peripheral surface of 3b, that is, a step 3c '. Then, the pair of rollers 3 of the feed roller 3
The upper surface positions of a and 3b are provided so as to be lower than the upper surface positions of the idle rollers 2a and 2b by a predetermined distance D.

At a position slightly apart from the discharge port 1b of the stocker 1, that is, at the tip of the card C when the card C is in the stocker 1 about 2/3, the lower side is slightly lower than the position of the discharge port 1b. In addition, two friction plates 4a and 4b, which are made of flexible and are parallel to the longitudinal direction of the discharge port 1b and parallel to the wall surface 1a of the stocker 1, are provided.

The upper ends of the friction plates 4a and 4b are fixed to the frame F, and the lower ends of the friction plates 4b on the stocker 1 side are larger than those of the other friction plate 4a, as shown enlarged in FIG. 1A. Is also located above by the thickness t of one card C.

The stocker 1 is further equipped than the friction plates 4a and 4b.
The auxiliary feed roller 5 is provided at a position distant from, that is, at the tip of the card C when the card C is about 1/3 in the stocker 1. The auxiliary feed roller 5 is configured to be rotationally driven in the same direction as the feed roller 3 by the motor M via a transmission mechanism (not shown) (see arrow in FIG. 1).

A roller 6 with a torque limiter 6a is provided above the auxiliary feed roller 5 with a gap of the thickness t of the card C being maintained.

Next, the feeding operation of the apparatus of this embodiment will be described with reference to FIGS. 3 and 4.

Now, when a large number of cards C, C ... Are stacked on the stocker 1 and a known weight is placed on the uppermost card C, when the motor M rotates, the feed roller 3 becomes It rotates clockwise as shown by the arrow in FIG.

When the step 3c 'of the stepped roller 3c hits the card C, the card C is lifted upward, and when the step 3c' comes down, the card C is moved downward to give the card C a vertical movement. .

Due to this vertical movement and the position of the feed roller 3 side below the idle roller 2, only the card C at the lowermost stage moves separately to the ejection port 1b side.

The card C fed from the discharge port 1b hits the lower end of the friction plate 4a, bends the friction plate 4a, and is fed to the auxiliary roller 5 side. Then, it is sent to a data recording unit (not shown) via the auxiliary roller 5.

Most of the cards C are fed one by one from the discharge port 1b by the feed roller 3 described above. For example, when two cards C1 and C2 are in close contact with each other with a strong force, the feed roller 3 is used. It may be delivered in a two-ply state without being separated.

In this case, as shown in FIG. 3, since the lower card C only bends one friction plate 4a,
It can be easily moved to the auxiliary feed roller 5 side. However, since the upper card C2 must bend two friction plates 4a and 4b, the friction plates 4a and 4b
The movement is blocked at b, and only one card C is separated and fed out here.

When the two stacked cards C1 and C2 are in close contact with each other with a stronger force, the two friction plates 4a,
It is conceivable to pass 4b.

At this time, the auxiliary feed roller 5 and the roller 6 with the torque limiter 6a are forcibly separated from each other.

That is, when the two-layered cards C1 and C2 reach the auxiliary feed roller 6, only the lower card C1 can pass without the torque limiter 6a acting. However, the upper card C2 is braked by the action of the torque limiter 6a and is not sent to the data writing section.

As described above, in the apparatus of this embodiment, since only one card is fed to the data writing section by the above-mentioned three mechanisms, the feeding error is eliminated and the processing of the data writing section is smoothed. be able to.
