[0002]

2. Description of the Related Art The receipt has the name of the store and "calculation"
It is general that the common phrases such as characters are always printed. Therefore, conventionally, a receipt printer having a structure of imprinting such a fixed phrase as a stamp has been considered and put into practical use. An example thereof is shown in FIGS. 8 and 9.

Paper path 2 for guiding paper 1 to a fixed path
Is provided, and the printing unit 3 is disposed in the paper path 2. A stamp device 4 is provided on the upstream side of the paper path 2 with respect to the printing unit 3 so as to be positioned on the printing surface 1a side of the paper 1. The stamp device 4 is formed by a stamp body 5 and an impact means (not shown) for impacting the stamp body 5 inside the paper path 2. Here, the stamp body 5 is provided with a stamp surface 6 facing the paper path 2 on its front surface, an occlusion body 7 for supplying the stamp ink to the stamp surface 6 inside, and its occlusion surface on the back surface. An ink supply hole 8 for supplying the stamp ink to the body 7 is formed. In addition,
The stamp surface 6 is given a slight impregnation property, and has a standard phrase such as the name of the store or the letters of "calculation".

In such a structure, when the stamp body 5 is impacted toward the sheet 1 inserted in the sheet path 2, the impact causes the stamp ink to be supplied from the occlusion body 7 to the stamp surface 6 to cause the stamp. The content of the marking on the surface 6, that is, the name of the store and the cliché such as "calculation" are stamped on the paper 1. Then, sales information is printed on the paper 1 by the printing unit 3 in correspondence with the stamped portion. As a result, one receipt is completed.

However, when the stamp ink stored in the stamp body 5 is completely consumed, it is necessary to replenish the stamp ink. To replenish the stamp ink, the printer cover (not shown) is opened and the stamp body 5 is removed from the back side of the paper path 2. Then, a dropper 9 is inserted into the ink supply hole 8 formed on the back surface of the stamp body 5.
The tip portion of is inserted, and the stamp ink previously sucked into the dropper 9 is injected into the stamp body 5. Then, the stamp ink is impregnated in the occlusion body 7 and stored in the stamp body 5.

[0006]

However, in order to replenish the stamp ink, the stamp body 5 must be removed from the apparatus, so that there is a drawback that the work for replenishing the stamp ink is complicated. Further, when the stamp body 5 is removed from the apparatus, if the stamp surface 6 touches a hand or clothes, the stamp ink may stain the hands or clothes.

[0007]

SUMMARY OF THE INVENTION According to the present invention, a paper path for guiding a paper to a predetermined path and arranging a printing unit for performing a predetermined printing on a printing surface of the paper in the path, and opening the paper path.
