BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a feeding device for a card printing unit in a card processing device.

[0002]

2. Description of the Related Art A card processing apparatus which performs magnetic recording on one side of a prepaid card and prints and records the date and time of use and balance on the other side is already known. An example is shown in FIG.
It will be described based on. In card passage O, insert card
A take-in / discharge roller pair 2, a first magnetic head 3, a second magnetic head 4, a feed roller pair 5, a printing unit 6, a transport roller pair 7, and a card hopper 8 are provided in this order from the discharge port 1. . The printing unit 6 includes a printing head 6a formed of a flat thermal head and a platen roller 6b.
The card taken in from the card insertion / ejection slot 1 is
Magnetic information is read or magnetic information is recorded by the second magnetic head 3.4. The card that has completed the processing of the magnetic information is sent to the printing unit 6 by the feed roller pair 5, and the information such as the date and time of using the card and the balance is printed as visible information. The printed card is discharged from the card loading / unloading port 1. The card hopper 8 stores and stacks a new card, and sends out the new card when issuing the new card. Again,
The date of card issuance is printed and magnetic information is recorded. Therefore, the printing unit 6 performs a printing operation when the card is sent in the forward direction a and the reverse direction b or when the card is sent in both directions.

Referring to FIG. 4, details of the printing unit 6 will be described. The print head 6a is supported so as to be displaceable about a pivot 6c. When a card (not shown) enters the printing unit 6, it is placed at a retracted position shown by a solid line, and when the card enters a predetermined printing position, it is shown by a chain line. And the card is pressed against the platen roller 6b. The print head is displaced by a solenoid or a spring (not shown), and the retracted position is controlled and controlled by a stopper (not shown). When the card is sandwiched between the print head 6a and the platen roller 6b, the card is conveyed by receiving the feeding action of the platen roller 6b.

On the other hand, the card path is divided into a card path O on the magnetic heads 3 and 4 side and a card path O1 on the card hopper 8 side with the printing section 6 interposed therebetween in the card conveying direction. This is because, as shown in FIG. 2, since the print head 6a is formed to have a length larger than the width of the card passage, a continuous card passage from the card intake / discharge port 1 to the card hopper 8 cannot be formed. Due to that.

[0005]

The card sent to the printing unit 6 in the forward direction a is sent between the print head 6a and the roller 6b which are separated from the platen roller 6b. Tip is print head 6
In order not to abut against the end surface 6aa (see FIG. 5), the tip Ha of the downwardly bent portion of the guide member forming the card passage, the head upper surface 6ab, and the step H need to be kept as small as possible. There is. The step H is formed between the upper surface 6ab of the print head in the retracted position and the front end Oa of the bent portion.
This shows the difference from. In order to avoid the card jam in the forward direction a, the head upper surface 6ab should be positioned lower than the bent front end portion Oa. However, when the card is fed in the reverse direction b, the card is bent. There is a problem in that the sheet is abutted against the leading end Oa and is not conveyed.

[0006] Also, the bent portion tip Oa and the head end face 6a
If the gap G with respect to “a” is large, the leading end of the card easily enters this gap. Therefore, at present, the relative position between the print head and the end of the guide member is controlled so that the gap G is made as small as possible along with the step H. However, there is a problem that the card is caught in the head portion.

Accordingly, an object of the present invention is to provide a feeding device for a card printing unit capable of performing stable card feeding in the printing unit.

[0008]

According to the present invention, there is provided a card printing section for feeding a card to a printing section having a print head and a platen roller arranged opposite thereto by a feed roller pair provided in a card path. In one of the feed roller pairs, one of the feed roller pairs arranged on the same side of the card path as the print head is arranged closer to the print head side than the other roller, and is fed by the feed roller pair. The leading end of the card is directed toward the platen roller, and the feed roller pair is arranged at a position where the leading end of the card faces the print head by the platen roller.

[0009]

In the card fed by the feed roller pair, one roller located on the print head side is located on the head side with respect to the other roller, so that the card proceeds in a direction away from the head surface of the print head and prints. Department is entered.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.

In FIG. 1 and FIG. 2, a printing unit 60 includes a printing head 61 composed of a thermal head, and a platen roller 62 for feeding a card during a printing operation. The feed roller pair 50 includes one drive roller 51 located on the same side of the card path O as the head, and the other driven roller 52 that rotates while pressing against the roller 51. Either the roller 51 or the roller 52 may be a driving roller.

The card path O on the left side of the figure comprises guide members Ob and Oc for guiding the card C up and down, and guide side plates Od and Oe for guiding both side edges of the card.
The card path O1 on the right side in the figure includes guide members O1a and O1b for guiding the card C up and down, and guide side plates O1c and O1d for guiding both side edges of the card. The guide member O1b has its tip end abutted on the upper surface of the head, and is provided so as to be displaceable so as to follow the print head 61 that is displaced.

The driving roller 51 and the driven roller 52
The line connecting the support shafts 51a and 52a is not orthogonal to the card path O and is inclined toward the print head. That is, the driving roller 51 is driven by the driven roller 52 in the card path O.
Rather than the print head 61 side. In other words, the drive roller 51 and the driven roller 52 are disposed such that the abutting portion (nip portion) N of the two rollers is located closer to the head than a vertical line extending down to the card path O from the center of rotation of the support shaft 52a. It will be.

The step between the leading end Oa of the guide member Oc and the head surface 61b (see reference numeral H in FIG. 5) is such that the head surface 61b of the print head located at the retracted position is positioned higher. It is enough if it is set. On the other hand, the tip Oa
Since the gap between the head end face 61a and the head end face 61a (see reference numeral G in FIG. 5) does not need to be strictly controlled if the step H is set as described above, it is sufficient to set the gap as small as possible. Therefore, the component accuracy and the assembly accuracy may be relatively low, and the cost can be reduced.

The operation of the embodiment configured as described above will be described. FIG. 1 shows a state in which the card C to be printed is sent to the printing unit 60, and the print head 61 is located at a retracted position separated from the platen roller 62. When the conveyed card C is nipped by the feed roller pair 50 rotating in the direction indicated by the arrow, the card C is moved by the drive roller 51 being positioned closer to the head than the driven roller 52. , The tip Ca of which is
The paper is sent to the printing unit 60 while being directed to the second peripheral surface 62a. That is, the leading end of the card advanced toward the peripheral surface of the platen roller 62 does not engage with the end surface 61a of the print head 61 even if it is curled downward.

The leading end Ca of the card abutting against the peripheral surface of the platen roller 62 is rotated by the rotation of the roller.
The print head 61 is guided downward toward the upper surface 61b of the retracted print head 61. When the card advances to the predetermined position,
The print head 61 is urged toward the print position by a card position detection signal of a card sensor (not shown), and starts printing while pressing the card C against the peripheral surface of the platen roller 62. When the printing operation is started, the driving roller 5
1 is stopped, and the roller 51 and the driven roller 52 rotate following the card fed by the platen roller 62. When the printing operation on the card C is completed, the print head 61 is displaced to the retracted position shown in FIG.

Next, the operation when the card is sent in the reverse direction b will be described. When the card is sent to the printing section,
The print head 61 is located at the evacuation position, and guides the card that has advanced toward the card path O. At this time, since the head surface 61b of the print head 61 is positioned higher than the bent front end portion Oa of the guide member, the front end of the card does not engage with the front end portion Oa.

In the embodiment described above, a thermal head is used as the print head. However, the print head of the present invention may be another type of print head such as a wire dot head.

[0019]

As described above, according to the feeder of the card printing unit of the present invention, in which the feed roller arranged on the same side as the print head is arranged close to the print head, the curled card is Can be sent stably. In addition, the dimensional control of the relative position between the guide member and the print head constituting the card passage becomes easy, and the cost can be reduced.
