[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a card printing unit feeding device in a card processing device.

[0002]

[Prior art]

 There is already known a card processing device that magnetically records one surface of a prepaid card and prints and records usage date and balance on the other surface. One example thereof will be described with reference to FIG. In the card passage O, the card insertion / ejection port 1 is sequentially taken in and out, the first and second magnetic heads 3, the second magnetic head 4, the feed roller pair 5, the printing section 6, and the conveyance roller pair 7 Also, a card hopper 8 is provided. The printing unit 6 is composed of a printing head 6a composed of a flat type thermal head and a platen roller 6b. The magnetic information of the card taken in from the card insertion / ejection slot 1 can be read or recorded by the first and second magnetic heads 3.4. The card which has finished processing the magnetic information is sent to the printing unit 6 by the feed roller pair 5, and information such as the date and time when the card is used 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 new cards in a stacked manner and sends out the new cards when issuing the new cards. Also in this case, the card issue date and the like are printed and the magnetic information is recorded. Therefore, in the printing unit 6, the printing operation is performed when the card is sent in either the forward direction a or the reverse direction b or when it is sent in both directions.

Details of the printing unit 6 will be described with reference to FIG. The print head 6a is displaceably supported with a pivot 6c as a center, and is placed in a retracted position shown by a solid line when a card (not shown) enters the printing unit 6, and is shown by a chain line when the card reaches a predetermined print position. The card is displaced as shown to press the card against the platen roller 6b. The print head is displaced by a solenoid (not shown) or a spring, and the retracted position is 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 being fed by the platen roller 6b.

On the other hand, the card passage is divided into a card passage O on the side of the magnetic heads 3 and 4 and a card passage O1 on the side of the card hopper 8 so as to sandwich the printing portion 6 in the card conveying direction. As shown in FIG. 2, since the print head 6a is formed with a length larger than the width of the card passage, a continuous card passage cannot be formed from the card loading / unloading port 1 to the card hopper 8. Due to that.

[0005]

[Problems to be solved by the device]

 By the way, the card sent to the printing section 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, but the end of the card is the end surface 6aa of the print head 6a ( (See FIG. 5), it is necessary to manage the tip end Oa of the downward bending portion of the guide member forming the card passage, the head upper surface 6ab, and the step H as small as possible in order not to collide with each other. This step H indicates the difference between the upper surface 6ab of the print head in the retracted position and the bent portion front end Oa. In order to avoid the card jam in the forward direction a, the head upper surface 6ab should be positioned lower than the bent portion tip end Oa. In this way, the card when sent in the backward direction b is bent. There is a problem that the tip Oa hits the tip portion Oa and is not conveyed.

Further, if the gap G between the bent portion tip portion Oa and the head end surface 6aa is large, the card tip easily enters this gap. Therefore, at present, the relative position between the print head and the end portion of the guide member is controlled so that the gap G as well as the step H is controlled as small as possible. However, there is a problem that the card is caught in the head part.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a card printing unit feeding device capable of stable card feeding in the printing unit.

[0008]

[Means for Solving the Problems]

 The feeding device of the card printing unit of the present invention is a device for feeding a card onto the print head of the printing unit through a feed roller pair disposed in the card passage, and is the same as the printing head of the card passage of the feeding roller pair. One of the rollers disposed on one side is disposed on the print head side with respect to the other roller.

[0009]

[Action]

 A card sent by a pair of feed rollers has one roller located on the print head side located closer to the head side than the other roller. To be entered.

[0010]

【Example】

 Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.

In FIG. 1 and FIG. 2, the printing unit 60 includes a print head 61 which is a thermal head and a platen roller 62 which feeds a card during a printing operation. The feed roller pair 50 is composed of one drive roller 51 located on the same side as the head in the card passage O, and the other driven roller 52 that rotates in pressure contact with the roller 51. Either the roller 51 or the roller 52 may be a driving roller.

The card passage O on the left side in the drawing is composed of guide members Ob and Oc for guiding the upper and lower sides of the card C, and guide side plates Od and Oe for guiding both side edges of the card. The card passage O1 on the right side of the drawing is composed of guide members O1a and O1b for guiding the upper and lower sides of the card C, and guide side plates O1c and O1d for guiding both side edges of the card. The leading end of the guide member O1b is in contact with the upper surface of the head, and the guide member O1b is displaceable so as to follow the displacing print head 61.

Further, in the drive roller 51 and the driven roller 52, the line connecting the respective support shafts 51a, 52a is not orthogonal to the card passage O and is inclined toward the print head side. That is, the drive roller 51 is arranged closer to the print head 61 than the driven roller 52 in the card passage O. In other words, the driving roller 51 and the driven roller 52 are arranged such that the contact portion (nip portion) N of both rollers is located closer to the head side than the perpendicular line from the rotation center of the support shaft 52a to the card passage O. Has been done.

Then, the step (see reference numeral H in FIG. 5) between the tip end portion Oa of the guide member Oc and the head surface 61b is arranged so that the head surface 61b of the print head placed in the retracted position is positioned higher. It only needs to be set. On the other hand, the gap between the tip portion Oa and the head end surface 61a (see reference numeral G in FIG. 5) does not need to be strictly controlled if the step H is set as described above, so it is sufficient to set it as small as possible. Is. 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 fed into the printing unit 60, and the print head 61 is placed at a retracted position separated from the platen roller 62. When the conveyed card C is nipped by the pair of feed rollers 50 rotating in the direction of the arrow, the drive roller 51 of the card C is positioned closer to the head side than the driven roller 52. As a result, the leading edge Ca is directed to the peripheral surface 62a of the platen roller 62 and is sent to the printing unit 60. That is, the tip of the card that is 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 curls downward.

The card tip Ca, which abuts against the peripheral surface of the platen roller 62, is guided downward toward the upper surface 61b of the retracted print head 61 by the rotation of the roller. When the card advances to a predetermined position, the print head 61 is urged toward the print position by a card position detection signal from a card sensor (not shown), and the print operation is performed while pressing the card C against the peripheral surface of the platen roller 62. Start. When the printing operation is started, the feeding operation by the drive roller 51 is stopped, and the roller 51 and the driven roller 52 rotate following the card sent 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 fed to the printing section, the print head 61 is placed in the retracted position and guides the card that has advanced toward the card passage O. At this time, since the head surface 61b of the print head 61 is positioned higher than the bent front end Oa of the guide member, the front end of the card does not engage with the front end Oa.

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

[0019]

[Effect of device]

 As described above, according to the feeding device 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 side, the curl card can be fed stably. be able to. In addition, it is possible to easily control the size of the relative position between the guide member and the print head forming the card passage, and to reduce cost.
