Abstract

PURPOSE:To prevent a paper jam in inserting a paper by providing a paper guide movable toward a paper inlet port and moving the paper guide toward the paper inlet port when a carriage moved to one end of left and right ends so as to be out of a printing area. CONSTITUTION:A paper 100 housed in a front inserter is sent out by a feed roller 1 and inserted to this apparatus through a paper inlet port 9 so that the paper 100 is fed to a printing position (the position wherein a printing head faces to a platen 5). When the paper 100 is inserted, a carriage 2 moves at first to one end of left and right ends so as to be out of a printing area. Then, paper guide driving means 4 moves the paper guide 3 which has been located at a position as shown by the solid lines to a different position as shown by the chain lines. The paper is thus inserted, thereby making it possible to prevent a paper jam. After that, the carriage 2 returns into the printing area, and the paper guide 3 restores to the position shown by the solid lines. In this condition, the printing operation is started.

Description

[Detailed Description of the Invention] [Summary] With regard to a printer device equipped with a front inserter, the purpose of this is to prevent paper jams from occurring when paper is sucked in. In a printer device equipped with a paper guide and a carriage that guides and discharges paper sucked in from a mouth, the paper guide is provided so as to be movable toward the suction port, and the carriage moves toward either the left or right side when the paper is out of the printing area. The paper guide drive means is provided for moving the paper guide closer to the suction port when the paper guide moves to the end of the paper guide.

[Industrial application field]

The present invention relates to a printer device equipped with a front inserter.

[Conventional technology]

This type of conventional printer device has a pair of paper guides that guide and eject the paper fed out and sucked in from the front inserter. Among these, the paper guide on the front side (carriage side) in particular is constrained by the presence of the carriage and is mounted considerably below the paper intake port.

[Problems to be Solved by the Invention] As described above, in the conventional structure, the front paper guide is provided far below the suction port, so curled media or sheets with low rigidity often cause paper jams when the paper is sucked. was.

SUMMARY OF THE INVENTION An object of the present invention is to provide a printer device that can prevent paper jams from occurring during paper intake.

(Means for Solving the Problems) Fig. 1 is a diagram explaining the principle of the present invention, in which 1 is a feed roller provided on a front inserter installed in a printer device, 2 is a carriage, and 3 is a front side. 4 is a paper guide driving means. Reference numerals 5 and 6 are paper guides on the platen and back side, which are added for reference.

The carriage 2 is equipped with a print head 7, etc., which are added for reference, and is guided by a guide 8 to move in a direction perpendicular to the plane of the paper in FIG.

The paper guide 3 is provided so as to be movable in the direction of the arrow toward the suction port 9 of the printer device, and is normally positioned at the position indicated by the solid line.

The paper guide drive means 4 drives the paper guide 3 when the carriage 2 moves to either the left or right end outside of the printing area.
It has a function of moving the inlet 9 closer to the suction port 9.

[Function] The paper 100 stored in the front incircle is fed out by the feed roller, sucked into the device from the suction port 9, and supplied to the print section (the position where the print head 7 faces the platen 5). Ru. Printing on this paper is performed by moving the print head 7 along the platen 5 and operating it in a predetermined pattern at a predetermined time. During this printing, printing is performed by a predetermined protruding printing wire pressing the paper 100 against the platen 5 via an ink ribbon (not shown). The paper on which printing has been completed is guided by the paper guide 3.6 and discharged downward. The paper guide 6 is fixed and extends upward to a position close to the platen 5.

When sucking in the paper as described above, the carriage 2 is first moved to either the left or right end outside the print area.

As a result, the paper guide driving means 4 moves the paper guide 3, which has been positioned at the position indicated by the solid line, to the position indicated by the chain line close to the suction port 9.

Since paper suction is performed in this state, occurrence of paper jam, which has been a problem in the conventional structure in which the paper guide 3 is fixed at the position shown by the solid line, is prevented.

Thereafter, when the carriage 2 returns to the printing area, the paper guide 3 also returns to the position indicated by the solid line, and printing is started in this state.

〔Example〕

The present invention will now be described in detail with reference to FIGS. 2 and 3.

Fig. 2 is an explanatory diagram of the main part structure of the printer device of this example (Fig. 2 (a) is a front view, Fig. 2 (b) is a side view), and Fig. 3 is a detailed explanatory diagram of the main part of Fig. 2. In the figure, numeral 10 indicates a fixed guide. Note that the same reference numerals are used for the same members as in FIG. 1. A supplementary explanation of the configuration described in connection with FIG. 1 with reference to FIGS. 2 and 3 is as follows.

The paper guide 3 is rotatably supported by a support shaft 11.

Further, the paper guide drive means 4 includes a drive lever 12 and a return spring 13. The drive lever 12 is rotatably supported by a support shaft 14, and is normally shown in FIG. 2(a).
This positioning is achieved by the biasing force of a spring 13 provided between the bent portion 12a of the drive lever 12 and the locking tool 15 attached to the fixed guide 10. The bent portion 12a is locked to the upper part of the locking tool 15. One end 12b of the drive lever 1-2 is at a position where it engages with the carriage 2 when the carriage 2 moves to the left end outside the printing area, and the other end 12c is provided with an elongated hole 16. This drive lever 12 engages with the paper guide 3 via a pin 17 fitted into an elongated hole 16, so that the paper guide 3 is normally positioned at the position shown by the solid line in FIG. 2(a).

The upward movement of the paper guide 3 during paper suction is performed as follows.

When sucking paper, the carriage 2 is moved to the left end outside the printing area as shown in FIG. 2(a).

As a result, the drive lever 2 whose one end 1.2b engages with the carriage 2 resists the force of the spring 13 and moves to the second position.
The paper guide 3, which is engaged with the drive lever 12 via the pin 17, also rotates to the position shown by the chain line in FIG. 2(a). In this state, paper guide 3
The tip of the inlet 9 is connected to the suction port 9 as shown by the chain line in Fig. 2(b).
It has risen to a position close to . Therefore, when paper is sucked in this state, the sucked paper is guided to the paper guide 3 that is close to the suction port 9, and paper jams are prevented from occurring.

After paper suction is completed, the carriage 2 moves into the printing area and printing starts; however, at the initial stage of the movement of the carriage 2, the carriage 2 disengages from the drive lever]2, and the drive lever 12 is moved by the spring 13. The paper guy [3] returned to its original position (solid line position in Figure 2 (a)).
to return to. Therefore, the movement of the carriage 2 into the printing area is not hindered by the paper guide 3.

The paper on which printing has been completed is guided by the paper guide 3.6 and discharged.

〔Effect of the invention〕

As described above, according to the present invention, the paper guide is driven by the paper guide driving means that is activated when the carriage moves to either the left or right end outside the printing area when paper is sucked in, and the paper guide approaches the intake port. Since the paper to be sucked is guided by the paper guide, it is possible to prevent paper jams from occurring during paper suction.
