DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card printer for printing characters and numerals on the front and back surfaces of a prepaid card or the like using an ink transfer medium such as a thermal transfer film.

[0002]

2. Description of the Related Art Conventionally, a card printing machine that prints letters, numbers, logos, graphics, bar codes, and the like on the front and back surfaces of a prepaid card or the like using a thermal transfer film is shown in FIG.
Are known. Such a card printing machine has a configuration as shown in the figure, and when loading the card 100 into the hopper 101, the weight 103 suspended on the spring 102 is lifted and the card 100 is loaded. After that, this is brought into contact with the uppermost card 100 to apply a pressing force to the entire card 100. Thereafter, when the drive motor (first drive source) 104 is driven counterclockwise, the cut-out roller 105
Cut out 0 one by one. When the card 100 cut out and carried out of the cutout 101a is guided by the feed roller 106 and reaches the feed roller 107, when it is detected by a sensor (not shown), the sensor instructs the motor 104 to stop driving and , And instructs the drive motor (second drive source) 108 to drive counterclockwise. Thus, the card 100 conveyed to the roller 107 is conveyed to the printing unit 110 by the roller 107 and the pinch roller 109 corresponding to the roller 107.

The sensor detects that the card 100 is carried out from between the roller 107 and the roller 109, instructs the motor 108 to stop driving, and drives the motor 104 counterclockwise again. Then, the next card 100 is cut out. Thus, the motor 1
By alternately driving and stopping the drive between 04 and 108, the card 100 is cut out from the hopper 101 and transported to the print unit 110.

However, in the conventional card printing machine, a feeding roller 112 driven by a driving motor (third driving source) 111 is transported to the printing unit 110 while it is being conveyed.
To 115, and pinch rollers 116 and 117 corresponding thereto. The card 100 carried out between the rollers 107 and 109 is moved by the group of rollers to the printing unit 110. To be transported. Then, the thermal transfer film 119 accommodated in the cartridge 118 is simultaneously supplied to the gap between the heat generating head of the printing unit 110 and the roller (roller platen) 114 opposed thereto. Thus, the ink on the thermal transfer film 119 is transferred, and required characters and numerals are printed.

The thermal transfer film 119 of the cartridge 118 is wound around pulleys 118a and 118b attached to the cartridge 118, and is driven by a drive motor (not shown) (not shown) separate from the motor 111. However, the switching between the forward and reverse rotation is performed in conjunction with the forward and reverse rotation of the motor.
The operation is performed by operating the electromagnetic clutch built in each of a and 118b. Printed card 1
00 is a roller 115 and a pinch roller 1 responsive thereto.
20 and are conveyed and stored in a predetermined storage box 121.

[0006]

However, in the conventional card printer, the card is cut out and conveyed from the cut-out port separately by two drive motors, and furthermore, the card is carried into and out of the printing unit. Printing is carried out by using a configuration in which unloading is performed by one drive motor and driving of the thermal transfer film is performed by another drive motor, and furthermore, all card transport is performed by roller transport. There is a problem that the machine itself becomes large and expensive. In addition, it is difficult to reduce the size of the printing press itself because the card is conveyed with the longitudinal direction of the card to be printed as the advancing direction. At the same time, in addition to general letters and numbers, it is not possible to freely print original logos for preventing forgery, shop names, advertising phrases, and original data management codes for data processing.

In loading a card into the hopper, a heavy weight must be lifted and loaded one by one, so that the loading operation is not easy for a weak person such as a woman or an elderly person. At the cutout of the hopper, the contact with the cut card surface is so-called solid contact and frictional resistance is generated, so that there is a problem that it is difficult to carry out the card stably from the cutout. Conventionally, in order to prevent printing unevenness when printing required characters and numerals on a card, the gap between the heating head of the printing unit and the roller platen is conventionally adjusted by a skilled worker by visual inspection. Has the drawback that it requires considerable experience and is not easy for anyone to do. Furthermore,
In order to prevent the above-mentioned printing unevenness, it is necessary to maintain a constant angle of introduction and withdrawal of the thermal transfer film with respect to the heat generating head. And guide rollers (122, 123 in FIG. 7) so that the output angle is not affected.
Therefore, there is a problem that the printing press itself is increased in size by the provision of such rollers.

An object of the present invention is to provide a small and inexpensive card printing machine which has a short print processing time per unit time and can also print a unique logo, store name, advertisement, etc. to prevent forgery. To provide. It is another object of the present invention to provide a card printing machine which facilitates the operation of loading a card into a hopper and can stably carry out the card from a cutout of the hopper. Another object of the present invention is to provide a card printer capable of preventing printing unevenness when printing required characters and numerals on a card by simple means.

[0009]

In order to solve the above-mentioned problems, a card printing machine according to the present invention comprises a hopper for loading a card to be printed and a printing unit for printing required characters and numerals on the card. A first drive unit that cuts out the cards loaded in the hopper unit one by one into the cutout, and conveys the cut out cards to the printing unit unit, and a card that is conveyed by the first drive unit. And a second drive unit for driving the ink transfer medium supplied to and ejected from the printing unit while supplying the card to the receiving printing unit. The cards cut out one by one are conveyed to the printing unit. Then, the printing unit transfers the ink on the ink transfer medium to the card and prints it. As described above, the printing machine uses one drive source provided in the first drive unit to cut out and convey the card, and another drive source provided in the second drive unit to send the card to the printing unit. Since the supply of the card and the supply / ejection of the ink transfer medium to the printing unit, that is, the forward / reverse drive, are performed, the printing machine itself can be reduced in size and cost. Further, when the rectangular side is transported and supplied with the short side in the traveling direction, it is possible to contribute to downsizing of the printing press and shorten the time required for the printing process. In addition, in addition to general letters and numbers, it is also possible to freely print unique logos and store names for prevention of forgery, advertising phrases etc. and original data management codes for data processing etc. Become.

Further, in the card printing machine of the present invention, a movable lever is attached to the hopper, and the movable lever can be swung with one end thereof as a fulcrum, and the other end is pressed against the loaded card. A weight roller for applying pressure is mounted, and the weight roller is rotatably mounted. Further, a plurality of protrusions are provided at the cutout of the hopper portion, and the card surface cut out at the cutout is formed by the protrusions. Are brought into multipoint contact. The size of the protrusion depends on the size of the card, etc.
mm is preferable. Thus, when loading a card into the hopper, it is only necessary to swing the movable lever upward, and after loading the card, it is necessary to swing this downward to bring the weight roller into contact with the card. Is applied, and the cards are cut out one by one in accordance with the operation of the first drive unit. When the last card is cut out, the weight roller rotates to accelerate this cutting operation. In addition to being easy to load, no effort is required, and the last card can be cut out smoothly. Furthermore, at the cutout of the hopper, the contact with the card surface to be cut out is not solid, but localized and frictional resistance is reduced, so that the card can be stably carried out.

Further, in the card printing machine of the present invention, the first drive section includes a DC or AC drive motor (first drive source).
A cutting roller and a feed roller driven by the motor are provided, and a one-way clutch is provided on each of the cutting roller and the feed roller shaft.When a loaded card is cut out and transported to the printing unit, the motor rotates forward and backward. A sensor for instructing reverse rotation and alternately driving the cut-out roller and the feed roller is provided.
Thereby, for example, when the motor rotates forward and the one-way clutch of the cut-out roller shaft operates to supply the driving force of the motor to the cut-out roller, one of the cards loaded in the hopper by the cut-out roller is used. It is cut out at the cutout. During this time, the one-way clutch of the feed roller shaft does not operate, and the feed roller remains stationary. However, when the card discharged from the cutout reaches a predetermined position and is detected by a sensor provided at this position, the sensor instructs the motor to rotate in the reverse direction. With this instruction, the motor reversely rotates, and this time the one-way clutch of the feed roller shaft operates to supply the drive force of the motor to the feed roller, and the card is conveyed to the print unit by the feed roller. During this time, the one-way clutch of the cut-out roller shaft does not operate, and the cut-out roller is kept stationary because the pressing force from the weight roller is applied via the loaded card. Then, when the card passes through the predetermined position and this is detected by the sensor, the sensor instructs the motor to rotate forward and the cutting of the next card starts.

[0012] Since the card is cut out and conveyed alternately by the first drive unit having such a simple mechanism, the card is conveyed to the printing unit while maintaining a constant interval. This is extremely effective in reducing the size of the printing press itself. By the way, the sensor may be an electromagnetic sensor or an optical sensor, and its installation location is appropriately set so that the cut-out and the conveyance can be smoothly performed according to the forward and reverse rotation timings of the motor.

Further, the card printing machine of the present invention is provided with an adjusting means in the printing unit, so that the gap between the printing head of the printing unit and the roller platen disposed opposite to the printing head is adjusted. Adjustment is made so that when printing required characters and numbers on the card, printing unevenness does not occur. The adjustment by the adjusting means is basically performed at the start of printing, but is not limited to this, and may be performed in the middle of printing. Therefore, the method is simple and the degree of adjustment is quantitatively determined. Preferably, it can be grasped.

Further, the card printing machine of the present invention is provided with a conveying means disposed between the hopper section and the printing unit section and opposed to a plurality of feed rollers for conveying the card. is there. That is, this transport means supports a movable lever provided with a pinch roller responsive to one of the feed rollers so as to be swingable about a substantially central portion thereof, and one end of the movable lever is attached by an elastic member. The other end is slid with respect to the other one of the feed rollers. Thus, when the card is being conveyed between the feed roller and the pinch roller responsive to the feed roller, the thickness of the card is about the thickness of the card between the other end of the movable lever and the feed roller disposed at the other end. On the other hand, when the gap is generated, when the card is conveyed to the gap position, the other end slides with respect to the card on the feed roller by the elastic member. It is suitable when there is a place where conveyance by a group cannot be performed, and is extremely effective in reducing the size of the printing press itself. By the way, the sliding resistance generated when the other end of the movable lever slides against the card must not be too strong, and the tension of the elastic member is adjusted so that the card can be smoothly transported. Needless to say, it needs to be sized.

Further, the card printing machine of the present invention is provided with a cartridge accommodating the ink transfer medium supplied to and discharged from the print unit, and the size of the inlet and the outlet of the ink transfer medium provided in the cartridge is determined by: The angle at which the ink transfer medium is introduced into and out of the print head of the print unit can be adjusted to be substantially constant. Accordingly, even if the winding diameter of the ink transfer medium wound around the pulley of the cartridge changes as the cartridge is driven forward and backward, the ink transfer medium can be introduced into the print head without using a conventional guide roller. Since the lead-out angle can be maintained substantially constant, printing unevenness can be prevented, and furthermore, it can contribute to downsizing of the printing press itself. Further, a sensor installed for the purpose of detecting the end of the ink transfer medium or the like can be arranged near the ink transfer medium without being affected by the fluctuation of the winding diameter. By the way, it is preferable that the inlet and the outlet be adjustable depending on the size of the winding diameter wound around the pulley, but if the size is about 1 mm, the inlet and outlet angles are maintained substantially constant. There is no problem above.

Next, a control operation when printing is performed by the card printing machine will be described. First, the movable lever 8 is swung upward, the card 2 is loaded into the hopper section 3, and after loading, the card 2 is swung downward, and the weight roller 9 is brought into contact with the uppermost card 2 and the card 2 is swung. A pressing force is applied to the whole. Thereafter, when the motor 10 is driven to rotate forward, the one-way clutch 19 of the rotating shaft 13 is activated,
The rollers 14 cut out the cards 2 one by one. in this case,
The one-way clutch 20 of the rotating shaft 15 does not operate, and the roller 16 remains stationary. The weight roller 9 only applies a pressing force to the card 2 and does not rotate. However, when the last card 2 is cut out, the weight roller 9 also rotates to promote this cutting operation. Card 2 can be cut out smoothly. In addition, if the counting process is performed by a preset counter or the like, a predetermined number of cards 2 can be accurately counted.

When the card 2 that has been cut out and carried out of the cutout 3a is guided by the roller 18 and reaches the roller 16 and is detected by the sensor 21, the sensor 21 instructs the motor 10 to rotate in the reverse direction. The motor 10 is driven in reverse rotation. Then, the one-way clutch 20 of the rotating shaft 15 is activated, and the card 2 conveyed to the roller 16 is conveyed to the printing unit 4 by the roller 16 and the roller 17 responsive to the roller 16. In this case, the one-way clutch 19 of the rotating shaft 13 does not operate, and the roller 14 is kept stationary because the pressing force from the weight roller 9 is applied via the loaded card 2. Then, the sensor 21 detects that the card 2 has been carried out from between the rollers 16 and 17, and instructs the motor 10 to rotate forward, and the motor 10 is driven to rotate forward to cut out the next card 2. Start. In this manner, the card 2 is conveyed to the printing unit 4 while maintaining a constant interval by alternately cutting and conveying the card 2.

In the present card printing machine 1, a conveying means 29 is provided while the card 2 is conveyed from the hopper section 3 to the printing unit section 4, and feed rollers 22 to 26 driven by a motor 28 are provided. When the card 2 is being conveyed by the roller 22 and the roller 36 corresponding to the roller 22, a gap about the thickness of the card 2 is formed between the tongue 37 a of the lever 37 and the roller 23. When the card 2 is transported to the position, the spring 3
8 causes the tongue 37a to slide with respect to the card 2 on the roller 23, and the card 2 is smoothly conveyed to the next printing unit 4 while being guided by the tongue 37a.

The card 2 conveyed to the printing unit 4
In the gap A between the heating head of the unit body 40 and the roller 25 facing the heating head, the portion where the characters, numerals, etc. are printed is pressed by the heating head, and the heat transfer film 6 supplied to the gap A at that time is pressed. Is transferred to that location and printing is completed. The color of this ink can be changed by exchanging the thermal transfer film 6, and it goes without saying that multicolor printing can be performed. Then, the card 2 on which printing has been completed is transferred to the roller 26 and the roller 30 corresponding thereto.
Then, it is conveyed and stored in the predetermined storage box 44.

In this embodiment, the card printer 1 of the thermal transfer system has been described. However, it is needless to say that the present invention may be applied to a card printer of a thermal system. However, in this case, the thermal transfer film 6 as a thermal transfer medium is not necessary, and therefore, means for driving the thermal transfer film 6 is not required. However, thermal paper is used for the card itself or at least for a place where the card is printed. There must be.
