Description

[Detailed explanation of the invention] (Purpose) This invention relates to a small imprinter, and its purpose is to make it small and lightweight so that it can be easily carried by door-to-door salespeople, etc., and to have a simple structure. That's true.

(Conventional) Various types of imprinters have been available for use in credit sales transactions, but these were installed at the front desks of debart stores and specialty stores, and were unsuitable for portability due to their size and weight.

(Characteristics) The present invention has been improved in view of the above-mentioned circumstances, and it not only makes the conventional imprinter smaller, but also reduces the assembly strength without compromising the strength of the assembly due to the miniaturization. It has a structure that allows for rapid operation and ease of use.

(Structure) The structure of the present invention will be explained below. 1 is a printing base, and the card positioning frame 2 has a step slightly shallower than the thickness of the credit card A formed approximately in the center of the top surface.
A small protrusion 3 is provided within the frame and approximately at the center of the edge of the base 1, and a positioning frame 4 for the two right-angled sides of the printing form B is provided at an appropriate position on the base 1.
4 is provided, and a groove 5 along the longitudinal side of the base 1 and a step 6 in a direction perpendicular to the longitudinal direction of the groove are provided (see FIG. 5), and the small protrusion 3 A trough portion 7 is formed slightly inward from the edge portion opposite to the edge portion where the trough portion 7 is gradually lowered. 8 is a carriage guide, which has a rectangular guide hole 9 in the center and two screw guide holes 10, 10 on the edges.
Tightening screws 11, 11 are passed through the holes, and by screwing the screws into the screw holes drilled in the groove 5 of the base 1, the projections 12 and 13 into the groove 5 of the base 1
and position the carriage 14 in close contact with the stage 6.
The carriage guide 8 is fixed to the base 1 in such a way that the hole 9 in which it is mounted protrudes from the upper part of the base 1 (see FIG. 5). The carriage guide 8 is provided with stepped portions 21, 21 on the inner wall portions thereof facing in the longitudinal direction of the rectangular guide hole 9, respectively. Reference numeral 14 denotes a carriage, which is formed into a frame shape with an opening at the bottom, and shaft support holes 16 are provided in the left and right frame portions 15 of the frame shape, and each hole has an opening with a width slightly narrower than the diameter of the hole. 17 is provided, and a collar 18 is further formed on the upper part of the carriage 14 to support the carriage movably on the carriage guide 8.

A printing roller 19 is installed within the frame of the carriage 14.
is rotatably supported on a roller shaft 20 fitted in the shaft hole 16 of the frame portion 15, and both end portions of the roller shaft 20 protruding from both sides of the printing roller 19 are connected to steps provided in the carriage guide 8. Part 21,
21, and the printing pressure applied to the printing roller 19 is received.

The present invention has the above structure, and the assembly order is as follows. That is, carriage guide 8
With the carriage 14 inserted into the guide hole 9 from above, the roller shaft 20 with the printing roller 19 mounted thereon is pushed into the shaft support hole 16 from below the carriage, and the carriage 14 is inserted between the collar 18 and the roller shaft 20. The carriage guide 8 is mounted so as to be sandwiched between the shaft 20 and the shaft 20 from above and below. Next, the protrusion 12 and step 13 on the lower surface of the carriage guide 8 are inserted into the groove 5 of the printing base 1.
Then, the carriage guide 8 is brought into contact with the stepped portion 6 and fixed to the printing base 1 using the positioning screws 11 and assembled.

(Function) Since the present invention has the above-described structure, after the card A is inserted into the card insertion slot C shown in FIG. Insert it from D, place it on the card A, position it, and print preparation is completed. When the next carriage 14 is moved from one end of the guide hole 9 of the carriage guide 8 to the other end by fingers, the printing roller 1
9 presses the printing form 13 to print card data on the printing form.

(Effects) Since the present invention has the above-described structure and function, it can be made compact and lightweight, and is therefore convenient to carry. The structure of the sliding device of the carriage and the suspension device of the printing roller is improved because the carriage can be slid by the collar of the carriage and the printing roller can be installed from the lower opening in the frame of the carriage. This has the effect of allowing quick assembly. In addition, in this invention, the attachment area of the carriage guide to the printing base is wide in three dimensions, so the carriage guide is difficult to fall down after being fixed.Also, since a small protrusion is provided in the center of the card insertion slot, the carriage guide is attached by the small protrusion. Since the card is gently curved, it can be prevented from slipping out.Furthermore, since the base of the printing form insertion slot is slanted and is low, it has a wide opening for inserting the printing form, making it easy to set the printing form. This has a great practical effect because it is easy to use.
