Abstract

PURPOSE:To print a metallic character, by providing a printing form for forming a character to be printed, a printing form heating apparatus and an apparatus for pressing the printing form to the surface of a plastic card through a metal foil. CONSTITUTION:A stepping motor 1 is driven by a control circuit to perform the selection of a character to be printed and a moving table 10 is intermittently moved over a distance corresponding to one character every when one character is printed. A metal foil 13 wound by a reel and held by a heat resistant film is carried across under tension so as to be wound up by an empty reel 12 after passes under a printing wheel 2 and wound up by the empty reel 12 in small portions every when one character is printed. After the printing wheel 2 is heated by a heater, a plastic card 8 is placed on a table 9 and the selection of a character to be printed is performed by the control circuit to energize a solenoid 6.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printing device for printing characters on the surface of a plastic card.

When printing a series of numbers that differ for each card on the surface of a large number of plastic cards, it is important to be able to print clearly and to be able to use it immediately without spending time on drying.

Therefore, there has been a desire for an inexpensive printing device for plastic cards that satisfies these conditions and is easy to operate.

This invention was devised to meet such demands, and by pressing a heated stamp onto the surface of a plastic card through a metal foil such as gold foil, silver foil, or aluminum foil,・It is configured so that metallic characters are printed on the surface of the card.

As shown in Figure 1, a stepping motor (1) placed on a moving table (10) and a shaft (4) of this motor (1)
) is attached to the tip of the printing shaft (2) with a stamp engraved around it, and only the printing part of this printing shaft (2) is exposed downward, the rest is covered, and the support rod (7) The heating cover (3) is supported by a heating cover (3), and further includes an electromagnetic solenoid (6) for pressing the printing shaft (2) for a certain period of time onto the surface of the plastic card (8) placed on the stand (9). There is.

A sleeve (5) is fitted into the middle part of the shaft (4), and the electromagnetic solenoid (6) is connected to the sleeve (5).
) and the movable table (10) so as to be able to extend and contract. The heating cover (3) is provided with a heater, and by heating the heating cover (3) with the heater, the printing shaft (2) is indirectly heated.

By driving a stepping motor (1) by a control circuit (not shown), characters to be printed are selected, and the moving stage (10) is moved one character at a time to print each character.

As shown in the side view of Fig. 2, the metal foil (13) wound around the reel (11) and held by a heat-resistant film passes under the printing shaft (2), and then the empty reel (12) The paper is stretched out so that it can be wound up, and each time one character is printed, it is wound up little by little onto the empty reel (12).

When printing, after sufficiently heating the printing shaft (2) with a heater, place the plastic card (8) on the stand (9).
), and the control circuit selects the characters to be printed and energizes the electromagnetic lens (6).

Then, the metal foil (13) is heated through the stamp and is pressed onto the surface of the plastic card (8), thereby removing unnecessary metal foil other than the stamp.

In the embodiment described above, the printing shaft (2) is heated indirectly through the heating cover (3), but a sheathed heater is inserted into the center of the printing shaft (2), like a slip ring. Power may be supplied via a movable power supply means.

Furthermore, it is also possible to print in a dolatro matrix character form by using a heated dot printing wire instead of the printing shaft (2).
