Description

[Detailed Description of the Invention] The present invention relates to an equipment case equipped with a printer.

The purpose of the present invention is to prevent troubles that occur during printer operation, especially paper jams.

There are many devices that use serial printers, such as calculators, cash registers, and terminals, but cash registers in particular are used frequently and are handled by unspecified people, so regardless of the type of printer, paper,
There are many problems caused by ribbons, etc. Serial printers print receipts and journals with one head, so when the head moves away from one of the recording sheets, the recording sheet is fed.
At that time, if a load is applied at the paper outlet, the paper will sag.
There was a risk that the head would come back and cause serious problems, such as folding the paper and jamming it, damaging the head, or causing the ribbon to come off. The present invention is an attempt to eliminate such drawbacks, and one embodiment of the present invention will be described with reference to a cash register equipped with a printer having a dot-type print head.

FIG. 1 is a sectional view of the inscription portion and the recording paper exit portion of the case, and FIG. 2 is a partial external view of the case. To explain according to the diagram, 1 is the print head, 2
is a platen, 3 is a paper feed roller, 4 is a paper press roller, 5 is a paper guide, 6 is a stamp, 7 is a stamp receiving plate, 8 is a printer cover, 9 is a head cover, 1
0 is the stamp spring, 11 is the receipt paper, 12 is the upper case, 13 is the lower case, 14 is the table, 15
1 is a space provided in the table 14, 16 is a journal window, 17 is a writing table, 18 is journal paper, and 19 is an ink ribbon. Receipt paper 11
is sent between the print head 1 and the platen 2 by a paper feed roller 3 and a paper press roller 4. The print head 1 has a wire driven by a plunger,
A wire selectively driven by an external signal prints characters, symbols, etc. on the receipt paper 11 by moving in a direction perpendicular to the paper surface while selectively printing dots on the receipt paper via the ink ribbon 19. It's becoming like this. The receipt paper 11 is further printed with store names, trademarks, etc. by the stamp 6 and stamp receiving plate 7 attached to the head cover 9, passes through the cutter section, exits from the receipt paper exit section of the case, passes through the space 15, and then passes through the lower case. It can be taken out by an operator through a table 14 attached to 13. At this time, a stamp spring 10 attached to the printer cover 8 is placed at the stamp 6.
This prevents the receipt paper 11 from coming into contact with the stamp 6 having a printed surface on its surface, thereby preventing the receipt paper 11 from becoming stained.

On the other hand, the journal paper 18 is introduced into the printing section in the same way as the receipt paper 11, but it is rolled up from the writing table 17 toward the supply paper side, so that the print result can be seen through the journal window 16. Due to this structure, the journal paper 18 is pulled by the winding force at the printing head 1, and the paper does not sag even when the paper is fed. If the paper is stopped at the exit, the paper will accumulate inside the printer as it is fed. When the print head 1 is on the receipt paper 11, the receipt paper 11 is deformed at the stamp 6, but when the print head 1 is on the journal paper 18, the receipt paper 11 is initially deformed due to the stamp spring. Although the stamp 6 may be deformed, the final deformation occurs in the printed portion. Therefore, a paper jam occurs when the print head 1 returns. However, if the space 15 is provided as in the present invention, even if the receipt paper 11 is pressed from above, a load is applied at the end of the table 14, and the buckling phenomenon of the paper causes the arrow to appear in the space 15. The printer itself will not be damaged. Since the outer surface of roll paper is generally the printing surface, the space 15 is more effective on the lower side than on the upper side. Also, creating a step between the exit and the space is effective because the paper is more likely to buckle. Also, by making the length of the space larger than the space of each of the printing part and stamp part when the stamp spring 10 of the printing part and stamp part is brought close to the receipt paper,
This is an effective method since paper deformation tends to occur in the space of the case, and its effects are also great.

As the second, third, and fourth embodiments of the present invention, the third embodiment
, FIG. 4, and FIG. 5 will be explained. These are all cross-sectional views of the recording paper outlet of the case.
To explain the second embodiment with reference to FIG. 3, 17
18 is an upper case, 18 is a lower case, and 19 is a table having a space. 20 is a receipt cover, and 21 is a receipt paper. This is a modification of the embodiments shown in FIGS.
This prevents paper jams from occurring in the printer by preventing hands from touching the printer, making the above example more reliable. Next, the third embodiment will be explained with reference to FIG.
2 is an upper case, 23 is a lower case, and 24 is a receipt cover, which has walls 25 for guiding receipt paper 26 from both sides. In this case as well, the receipt paper 26 is pressed outside the receipt cover 24, but the lower side of the receipt cover 24 serves as a space for the receipt paper 26, so that no paper jam occurs inside the printer. Furthermore, in the case of the third embodiment, since the wall 25 is provided, even if the receipt paper 26 is intentionally shaken from side to side, there is little effect on the inside of the printer, and troubles may occur due to the load of the receipt paper from the front and back to the left and right. do not. Next, the fourth embodiment will be described with reference to FIG. 5. 27 is an upper case, 28 is a lower case, 29 is a table having a space, and 30 is a receipt cover, which has a wall 31 for guiding receipt paper 34. Furthermore, the receipt cover 30 is adapted to rotate around a shaft 32 and is normally raised toward the upper case 27 by a spring 33. In this case, the receipt paper 34 is connected to the table 29 and the receipt cover 3.
0 and is completely covered from the outside, receipt paper 3
The receipt paper 34 is deformed in the space created by the table 29 and the receipt cover 30 in response to an external load applied to the printer 4, thereby preventing jams inside the printer.
When printing a card using the printing unit, such as authentication printing, it can be done by placing the card on the receipt cover 30 and pushing the receipt cover 30 down to the same level as the table 29.

As mentioned above, by providing a space between the printer outlet and the receipt paper outlet of the printer case, even when a load is applied to the receipt paper from the outside, paper jams will not occur inside the printer and the case will not jam. It is possible to fasten it by deforming the receipt paper in the space. The present invention also has the effect that the receipt paper remains on the table even if it is cut using an automatic cutter or the like when issuing a receipt.

Furthermore, by attaching left and right guides to the receipt cover, the printer is protected against the receipt paper being swung left and right.

Furthermore, if the space is designed as a receipt paper stocker, the operator will not need to remove receipt paper each time receipts are issued continuously, which will reduce the chance of external load on the receipt paper and further reduce jamming.

In recent years, dot printers have been increasingly used in the cash register market, but in addition to their various advantages, there are also many problems with paper and ribbons due to rough handling by users. The present invention is effective as a countermeasure against paper jams, which is a major problem, and can prevent troubles caused by handling errors by operators. Also, the table is used for authentication printing, but the tip serves as a guide, and there are other parts as well, so there is no problem.
Moreover, there is no cost increase, and it is not bad in terms of design, and can be said to be a simple and useful method.

In the present invention, the space is made into a bag-like shape, but it is also possible to simply make a hole in the table.
