Abstract

PURPOSE:To offer a printer which requires no labor in setting and collecting a continuous paper by providing a pair of paper feed rollers at the side where an operator is present in front of a printing head and a platen, and providing a tractor which feeds said continuous paper to the side of said operator after the paper is printed. CONSTITUTION:When an operator inserts a front end of a continuous paper 1 from the front side of a printer into a paper suction port 2, the continuous paper 1 butts against a contacting point circumscribed with a pair of paper feed rollers 5, 6 at an end of the suction port 2. The paper feed rollers 5, 6 are rotated in an opposite direction from each other in the forwarding mode to bite the continuous paper 1 and send the paper between a printing head 3 and a platen 4. After the end of the continuous paper 1 reaches the position of a pair of tractors, pins 8 formed in the tractors 9 come into feed holes 7 continuously formed at both sides of the continuous paper 1. Thus, the continuous paper is completely set for a consistent supply thereof. Thereafter, the paper is automatically printed. Accordingly, the continuous paper can be set from the side of the operator and the printed result can be collected at the side of the operator.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printer mechanism, and particularly to the paper feeding direction and printing direction of continuous paper.

[Prior art] Conventionally, when printing on continuous paper, this type of printer
For example, as shown in the perspective view of FIG. 4, the continuous paper 20 is fed from the continuous paper inlet 22 on the opposite side of the platen 2l as seen from the operator's position, and the continuous paper 20 is fed onto the continuous paper on the platen on the front side as seen from the operator's position. Printing was performed by a print head 23 located at the top of the printer, and the continuous paper after printing was fed to the other side of the platen by a pair of tractors 24.

[Problems to be Solved by the Invention] In printing continuous paper using the conventional blink method described above, the continuous paper is not loaded into the printer. When loading the paper, the leading edge of the continuous paper is fed from the opposite side to the front side when viewed from the operator's position, and the paper is sandwiched between a pair of paper feed rollers, or the continuous paper feed hole is inserted into the tractor behind the print head or platen. There is a problem that it takes time to set the continuous paper, and if there is not enough space behind the printer, it is difficult to set the continuous paper and it is also difficult to collect the continuous paper with printed results. Ta.

SUMMARY OF THE INVENTION In order to solve these problems of the conventional technology, it is an object of the present invention to provide a new printer that does not require much effort to set and collect continuous paper.

[Means for Solving the Problems] In order to achieve the above object, the printer of the present invention is a printer that prints on continuous paper. a pair of circumscribed paper feed rollers that rotate to feed the continuous paper between the front print head and the platen;
The print head is located on the opposite side of the platen when viewed from the operator's position, and prints on the continuous paper on the platen located on the front side, and the continuous feed holes provided at both ends of the continuous paper after printing. , and a tractor that feeds paper toward the operator's position by driving the inserted bin.

[Function] Therefore, when loading continuous paper into the printer, the operator should feed the leading edge of the continuous paper in front along the continuous paper intake port, sandwich it between the pair of paper feed rollers visible in front, and then The paper is fed between the print head and the platen, and the continuous feed holes at both ends of the continuous paper are set on the tractor in front of the print head and platen, and then the continuous paper is printed and fed to the operator's side. All you have to do is secure a space to collect paper.

[Example] Next, an example of the present invention will be described with reference to the drawings.

Fig. 1 is a perspective view of an embodiment of the printer of the present invention, Fig. 2 is a partially cutaway perspective view of Fig. 1, Fig. 3(a), and Fig. 3(b).
figure. FIG. 3(C) is a side view showing the process of feeding continuous paper. A continuous paper inlet 2 is provided so that the continuous paper l can be supplied from the operator's position side, and when the leading edge of the continuous paper is fed along the continuous paper inlet 2,
a pair of circumscribed paper feed rollers 5.6 which can feed the continuous paper between the print head 3 and the platen 4 in the front by rotating in opposite directions with the continuous paper sandwiched therebetween; is provided so that it can be driven. The bins 8 are inserted into the continuous feed holes 7 provided at both ends of the continuous paper 1 fed out between the print head 3 and the platen 4, and the pair of paper feed rollers 5.6 are inserted.
A pair of tractors 9, which can be driven in conjunction with the continuous paper l to feed the printed continuous paper to the operator side, are installed at both ends of the continuous paper l at a position closer to the operator than the platen 4. The feed hole 7 is provided at a position where the included bottle 8 can be inserted. The print head 3 prints on the continuous paper l on the platen 4 while sliding on the spacing shaft IO all over the continuous paper 1 as necessary. That is, contrary to the conventional case, from the print head 3 located on the opposite side of the platen 4 when viewed from the operator's position,
Printing is performed on the continuous paper 1 on the front platen 4. The above description is based on the assumption that printing will be performed on continuous paper, but of course it is also possible to print cut sheets in this embodiment, and in the case of cut sheets, the cut sheet inlet 1
The paper is fed by a pair of paper feed rollers 5.6 onto the platen 4 in front of the print head 3. A paper release lever 12 that sets and releases the continuous paper 1 for printing, a paper guide lever 13 that sets and releases the cut sheet in a predetermined position,
The operation panel 14 and the like necessary for operating the printer are provided at predetermined positions.

Next, the operation of this embodiment will be explained. The operator inserts the leading edge of continuous paper 1 into continuous paper suction port 2 from the front side,
When fed along the wall, it hits the circumscribed contacts of the pair of paper feed rollers 5.6 located at the ends of the continuous paper intake port 2. Therefore, when the paper feed rollers 5 and 6 are driven manually or automatically, the paper feed rollers 5 and 6 rotate in the opposite direction to each other, hold the continuous paper l in their mouths, and continue to feed the continuous paper l. It is delivered between the head 3 and platen 4. After the tip 69; 15 of the continuous paper 1 arrives at the location of the pair of tractors 9 while performing trial printing as necessary, the tractors 9 are inserted into continuous feed holes 7 provided at both ends of the continuous paper 1. By inserting the bin 8 that has the bin 8, the setup for the continuous paper feeding operation is completed.From then on, by automatically proceeding with printing, the operator can feed and set the continuous paper from the operator's position. The printed results can then be collected at the operator's position.

〔Effect of the invention〕

As explained above, in the printer of the present invention, a pair of paper feed rollers are provided on the side of the operator's position in front of the print head and the platen, and are positioned on the side facing the continuous paper on the platen on the side of the operator's position to print. By having a tractor that feeds the continuous paper after printing to the operator's position, the operator can easily set the continuous paper from the front side, and after printing, the continuous paper can be set from the front side. This has the effect that it can be easily collected in a small space.
