Abstract

PURPOSE: To reduce a cost of manufacturing a card conveyer using a flat roller. CONSTITUTION: A bracket 3 is mounted in an upper surface a casing 2 of displaceably receiving a card 1, to arrange in parallel successively from a side of an inserting port 2a a flat conveying roller 4, large diametric idle gear 5a, small diametric idle gear 5b and a flat type motor 6 in the bracket 3. The flat conveying roller 4 is provided by tilting its axial line, with partly a peripheral edge part of the roller appearing in a card conveying surface, to provide a backup roller 7 in an opposed position, and the card is conveyed to be interposed between the flat conveying roller 4 and the backup roller 7. From the motor 6 leading to the roller 4 through each gear 5a, 5b is gear connected by a spur gear. Accordingly, by using the flat type motor, thinning size of a card conveyer can be realized, also by forming a constitution by a spur gear train, to eliminate necessity for using a member of high cost of manufacture like a helical gear, consequently to enable a product cost to reduce.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card carrier, and more particularly to a card carrier having a flat carrier roller whose axis is inclined with respect to a card carrier surface.

[0002]

2. Description of the Related Art Conventionally, Japanese Patent Laid-Open No. 2-75 by the same applicant
As disclosed in Japanese Patent No. 545, a flat type motor is used as a driving motor in an information transfer card transfer device in order to reduce the thickness of a casing, and the transfer roller is inclined with respect to the card transfer surface. A part of the peripheral edge of the transport roller (the portion closest to the card surface) is brought into contact with the card surface, and the opposing surface of the card is provided so as to correspond to the contact portion. There is one that works in cooperation with a pressing roller so that the card is conveyed while being nipped.

In the card conveying device having the above structure, the flat type motor and the transmission gear are arranged in a horizontal state with the card, and the transmission gear and the conveying roller are connected by gear coupling using a helical gear. Thus, the difference in the inclination of the axis between the transmission gear and the conveyance roller is corrected. However, in the helical gear, there is a problem that the product cost increases due to the structure of manufacturing the mold and the die cutting of the parts.

[0004]

SUMMARY OF THE INVENTION In view of the above problems of the prior art, the main object of the present invention is to reduce the product cost even if a flat roller is used for thinning. It is to provide a carrier.

[0005]

According to the present invention, such an object is provided between a casing for movably receiving an information transfer card and an opposing pressing means for inserting the card inserted in the casing. A flat transport roller provided with an axis inclined with respect to the card transport surface so as to be sandwiched and transported, a drive motor, and a transmission gear for transmitting a driving force from the drive motor to the flat transport roller. And a drive motor, the transmission gear, and the flat conveyance roller are rotatably arranged around mutually parallel axes and are gear-coupled to each other by a spur gear. It is achieved by providing.

[0006]

According to this structure, the axes including the transmission gears from the drive motor to the flat conveying roller are parallel to each other, and the gears connected to each other are composed of spur gears. Can be made as small as possible and a flat type motor can be used.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram of a preferred embodiment of the present invention.

FIG. 1 is a plan view showing a card reader / writer for accessing information to, for example, a magnetic card 1 as an information transfer card to which the present invention is applied.
In this embodiment, a card reader / writer capable of both reading and writing information is shown, but a device having only one of the functions may be used.

In the casing 2 of the carrier of the card reader / writer of the present invention, as shown in FIG. 2 and FIG. 3, upper and lower dividing members having a two-part structure are superposed on each other. The card insertion / removal opening 2a is opened at one end side in the longitudinal direction, and a pair of guide grooves 2b parallel to each other are provided inside along the longitudinal direction.
Therefore, the card 1 inserted from the insertion / removal opening 2a is longitudinally displaced and reciprocally received in the casing 2 while being guided by the both guide grooves 2b at its left and right edges.

A bracket 3 is attached to the upper surface of the casing 2 so as to cover substantially the entire surface thereof with a predetermined gap. On the bracket 3, a flat conveying roller 4, a large diameter idle gear 5a, a small diameter idle gear 5b, and a flat type motor 6 are arranged in parallel in this order from the insertion port 2a side.

The flat transport roller 4 is formed by coaxially integrating a disc-shaped spur gear 4a with a disc-shaped roller portion having substantially the same diameter on the lower surface side, and the entire circumference of the periphery of the roller portion. It has an annular protrusion formed downward in the axial direction and made of, for example, a rubber material, and an inclined axis inclined with respect to the transfer surface so that a part of the annular protrusion is exposed to the card transfer space in the casing 2. It is pivotally supported around it. The large-diameter idle gear 5a, the small-diameter idle gear 5b, and the motor 6 are attached to the bracket 3 so as to be rotatable about an axis parallel to the axis of the flat transport roller 4.

The spur gear 4a of the flat conveying roller 4 is provided with a large-diameter idle gear 5a and a small-diameter idle gear 5b.
A drive gear 6a fixed to the motor 6 is gear-coupled. Therefore, each gear is formed by a spur gear.

On the bottom wall side of the casing 2, the flat conveying roller 4 is supported so as to correspond to the portion of the casing 2 facing the card conveying space and is elastically urged toward the flat conveying roller 4 side. The backup roller 7 thus arranged is disposed as a facing pressing means. Then, the card 1 inserted in the casing 2 is conveyed while being sandwiched between the flat conveyance roller 4 and the backup roller 7.

A magnetic head 8 for transmitting and receiving information to and from the magnetic stripe of the card 1 is provided on the upper wall side of the casing 2 as shown in FIGS. A head pressing roller 9 is disposed on the bottom wall of the casing 2 at a position facing the head portion of the magnetic head 8 facing the casing 2. The card 2 is conveyed while being sandwiched between the magnetic head 8 and the head pressing roller 9, and signals are transmitted and received to and from the magnetic stripe by the magnetic head 8 during the conveyance.

In the card transporting device thus constructed, the driving force of the motor 6 is transmitted to the flat transporting roller 4 via the gear train in which the spur gears are gear-coupled to each other.
Since the flat transport roller 4 rotates about the axis inclined to the card transport surface, the card 1 can be transported while being sandwiched between a part of the flat transport roller 4 and the backup roller 7. . In the present embodiment, the motor 6 is rotated normally and reversely to insert and remove the card 1 from the insertion / removal opening 2a.

[0016]

As described above, according to the present invention, from the drive motor to the flat conveying roller via the transmission gear, the spur gears are gear-coupled to each other, so that the inclination of the axis can be minimized and the flat motor can be used. By using
The card carrier can be made thin, and the structure of the spur gear train does not require the use of a member having a high manufacturing cost such as a helical gear, so that the product cost can be reduced.
