Abstract

(57) [Summary] [Purpose] To enable stable printing without being affected by the difference between the amount of movement of an ink ribbon and the amount of movement of a stage on which a card is placed. [Structure] The card printing device includes an ink ribbon 3 coated with heat-melting or sublimation ink stretched between a supply roller 1 and a take-up roller 2, and a stage 4 on which a card-shaped recording medium C is placed. and a thermal head 5, and during printing, the stage 4 is moved while the take-up roller 2 is stopped, and the supply roller 1 is kept free.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention adds a thermal head to cards such as magnetic cards, optical cards, and IC cards. The present invention relates to a device for printing images such as faces, names, etc., and characters.

0002

[Conventional technology]

Conventionally, card printing devices used to create various cards, etc. A car with an ink ribbon stretched between a feed roller and a take-up roller placed on a stage. The thermal head is heated while the thermal head is pressed against the card-shaped recording medium. The required printing is performed on the card-like recording medium using the printer, but the stage must not be moved during printing. The ink ribbon is moved by rotating a take-up roller.

0003

[Problem that the idea aims to solve]

However, as with the above-mentioned card making device, the winding process occurs as the stage moves. When the ink ribbon is moved by rotating the take-up roller, the take-up roller and supply roller The diameter of the ink ribbon changes over time, so the amount of winding of the ink ribbon changes depending on the amount of printing. However, it is difficult to keep the amount of movement of the ink ribbon constant according to the amount of movement of the stage. As a result, the ink of a predetermined color on the ink ribbon is matched to a predetermined location on the card. This caused the image to deteriorate.

0004

[Means to solve the problem]

In order to solve the above problems, this invention has an ink ribbon between the supply roller and the take-up roller. This ink ribbon is placed on a card-shaped recording medium placed on a stage. When printing by pressing with a multi-head, the take-up roller is stopped and the stand is pressed. In addition to moving the feed roller, the feed roller is free.

[0005]

[Effect]

During printing, the take-up roller is stopped and the stage is moved while supplying Since the roller is in a free state, it is heated by the thermal head and the card is The ink ribbon is attached to the recording medium, and the ink ribbon is moved from this attachment position. Moves integrally with the stage as the stage moves.

[0006]

【Example】

Embodiments of the present invention will be described below with reference to the accompanying drawings. Here, Figure 1 is based on the present invention. FIG. 2 is a diagram showing the configuration of the main parts of the card production device, and FIG. 3 is a diagram showing the configuration of the main parts when printing. FIG. 4 is a configuration diagram of the winding mechanism section of the device, and FIG. 4 is a side view of the winding mechanism section.

[0007] The card printing device according to the present invention has a tension roller between a supply roller 1 and a take-up roller 2. an ink ribbon 3 coated with heat-melting or sublimable ink, and a card-shaped recording medium. It includes a stage 4 on which a body C is placed, and a thermal head 5.

[0008] Then, when starting printing from the state shown in Figure 1 at the time of printing start, this printing start At this point, the take-up roller 2 is not rotating, and the supply roller 1 is free (rotating automatically). ). On the other hand, when printing with the thermal head 5, the stage 4 must be moved. While pressing the ink ribbon 3 against the card-shaped recording medium C using the thermal head 5, Power is supplied to the heating resistor of the multihead 5 to heat the ink on the ink ribbon 3 and print the card. This is done by transferring it to a shaped recording medium C.

[0009] At this time, as mentioned above, the take-up roller 2 is not rotating, and the supply roller 1 is not rotating. Since it is in a free (free to rotate) state, the inlet heated by the thermal head 5 The ribbon 3 is lightly attached to the card-shaped recording medium C, and therefore the ribbon 3 is lightly attached to the card-shaped recording medium C, When the stage 4 moves, the ink ribbon 3 moves integrally with the stage 4. The state shown by the solid line in FIG. 2 is reached.

0010 After printing is completed, the take-up roller 2 and the thermal A drive roller 6 and a sub-roller rotated by a drive motor 8 between the drive roller 6 and the head 5 7, and an encoder 9 is attached to the shaft of the drive motor 8 to control the rotation of the drive roller 6. The amount of rotation, that is, the amount of movement of the ink ribbon 3 is detected by the amount of movement detection sensor 10, and this detection result is A certain amount of the ink ribbon 3 is wound up by a winding roller 2 according to the result. Then the next print to move to. Note that the wound state is shown by imaginary lines in FIG.

[0011] In addition, the positioning of the ink ribbon 3 is performed using a supply roller 1 and a thermal roller as shown in FIG. When passing through the sensor 12 via the positioning roller 11 provided between the head 5 and the conduct. Specifically, the ink ribbon 3 may be yellow (Y), magenta (M), If you use four-color ribbons of cyan (C) and black (Bk), yellow (Y) This is done by detecting the level difference between and magenta (M). After this, the movement amount detection sensor 1 0 to move the ink ribbon 3 by a predetermined amount.

0012

[Effect of the idea]

As explained above, according to the present invention, the take-up roller is stopped during printing. Since the stage was moved in a free state and the supply roller was left in a free state, the It is possible to perform stable printing with almost no influence from the movement of the link ribbon. Wear.
