Description

[Detailed description of the device]

[0001]

[Industrial applications]

  The present invention has a thermal head for cards such as magnetic cards, optical cards, and IC cards. The present invention relates to a card printing device that prints facial photographs, images such as names, and characters.

[0002]

[Prior art]

  In the conventional card printing device used to create various cards, For example, as described in JP-A-62-11370, the supply roller and the winding Card-shaped recording medium in which an ink ribbon stretched between rollers is placed on a stage And press the thermal head to heat the thermal head. Required printing is performed on the recording medium. And the stage is moved during this printing. While rotating the winding roller, the ink ribbon is moved.

[0003]

[Problems to be solved by the device]

  However, in the conventional card printing device described above, the stage is not printed at the time of printing. When the thermal head starts to be pressed after the start of moving the Then, since the ink ribbon is moving while moving the stage, the winding roll The diameter of the roller and supply roller changes over time, and the winding amount of the ink ribbon depends on the printing amount. Fluctuates. Therefore, adjust the movement of the ink ribbon to the movement of the stage. It is difficult to keep constant, and as a result, the ink of a given color on the ink ribbon is The image printed on the card is deteriorated because it cannot be aligned with the designated area on the card. Was the cause.

【Example】

  The card printing device of the present invention will be described below with reference to the accompanying drawings. Main consideration As shown in FIG. 1, the proposed card printing apparatus includes a supply roller 1, a winding roller 2, and a supply roller 2. The heat-melting or sublimable ink stretched between the supply roller 1 and the take-up roller 2 is used. Ink ribbon applied 3, Stage 4 on which card-shaped recording medium C is placed 4, Thermal It is composed of a head 5, a driving roller 6, sub rollers 7 and 8, and a sensor 9. The card printing apparatus of the present invention and the conventional card printing apparatus are configured so that some components are moved. However, the first to third embodiments will be described below.

[0006]   [First embodiment]   When printing is started from the print start state shown in Fig. 1, the winding The roller 2 is stopped without rotation, and the supply roller 1 is free (rotatable) State. Then, printing on the card-shaped recording medium C by the thermal head 5 is performed as follows. Is done like. After the movement of the stage 4 is started, the ink is moved by the thermal head 5. The ribbon 3 is pressed against the card-shaped recording medium C. Furthermore, move the stage 4 in the direction of the arrow in the figure. While moving the power supply to the heating resistor of the thermal head 5, The ink is heated and transferred to the card-shaped recording medium C.

[0007]   At this time, as described above, the take-up roller 2 is stopped and the supply roller 1 is free. -The ink ribbon 3 heated by the thermal head 5 is a card The recording medium C is lightly attached. Therefore, when the stage 4 moves, In response to this movement, the ink ribbon 3 moves integrally with the stage 4 and the state shown in FIG. It becomes a state.

[0008]   After printing, as shown in FIG. 3, the thermal head 5 is attached to the card-shaped recording medium. The ink ribbon 3 is retracted upward with respect to the body C, and the drive roller 6 moves the ink ribbon 3 in the direction of the arrow in the figure. And the take-up roller 2 in the direction of the arrow in the figure to move the ink ribbon. Take up a certain amount of 3. The drive roller 6 is an ink ribbon formed by the take-up roller 2. 3 for constantly moving the ink ribbon 3 regardless of the winding amount of It Then, as shown in FIG. 4, the stage 4 is moved in the direction of the arrow in the drawing. It returns to the position before printing shown in 1, and shifts to printing of the next color. In this way yellow , Magenta, cyan, and if necessary, print in each color of black Printing is completed.

[0009]   Thus, with the configuration of the first embodiment, the winding roller 2 is rotated after the printing is completed. When rotated, the ink ribbon 3 becomes the print start position for the next color. And stay 4 is returned to the print start position, so it may be affected by the movement of the ink ribbon. Absent.

[0010]   [Second Embodiment]   In the second embodiment, the movement states of the take-up roller 2 and the stage 4 after printing is completed. Only the difference is. Also, in the second embodiment, the winding roll is The roller 2 is stopped and the supply roller 1 is free. Shown in Figure 5 After printing is finished, rotate the take-up roller 2 in the direction of the arrow in the figure While winding the ribbon 3 a certain amount, move the stage 4 in the direction of the arrow at the same time. Let Then, the stage 4 is returned to the position before printing shown in FIG. 1 and the next printing is performed. To do. In this way, according to the configuration of the second embodiment, the winding roller 2 can be used after printing is completed. Since the stage 4 is returned to the print start position at the same time when the ink ribbon 3 is rotated, The print start position for the next color will not be affected by the movement of the ink ribbon. Yes. Further, the second embodiment shortens the printing operation time of one card as compared with the first embodiment. You can do it.

[0011]   [Third Embodiment]   In the third embodiment, movement of the take-up roller 2 and the stage 4 during printing The aspects are different. Then, in the third embodiment, when the printing starts, the supply low La1 is in a free state. Fig. 6 shows stage 4, thermal head 5, take-up roller 2 shows the operation timing of No. 2. In addition, for comparison, the conventional card printing device The operation timing of the take-off roller is also shown.   As shown in FIG. 6, in the conventional card printing apparatus, the movement of the stage 4 is started. At the same time when the pressing of the thermal head 5 is started (printing is started), the winding roller 2 is rotated. However, in the card printing apparatus of the third embodiment according to the present invention, the thermal head The take-up roller 2 is rotated with a delay of a predetermined time X from the start of printing of No. 5. That is, the winding start time of the ink ribbon 3 is delayed by a predetermined time X from the start of printing, Winding should be terminated at the same time as the movement of stage 4 is completed, or Delay the large time X and finish the winding. Since the printing time for one color is about 3 seconds, , Time X is about 0.5 seconds. In this way, if the configuration of the third embodiment is adopted, It is not affected by the movement of the ribbon 3.

[0012]

[Effect of device]

  As described in detail above, the card printing apparatus of the present invention is configured as described above. Therefore, the difference between the amount of movement of the ink ribbon and the amount of movement of the stage on which the card is placed is Not affected by Therefore, the image does not deteriorate, and Can be printed.
