Abstract

PURPOSE:To fit a slip to either of stoppers and properly insert the edge of the slip between rollers by providing two different kinds of stopper to stop paper, and arranging one stopper below the rollers and the other above the rollers. CONSTITUTION:A slip with a lower edge pasted 2a is inserted from above guided by a guide 1. The slip 2a passes between a card holder 4 and a platen 3 and stops riding on a L-shaped block 7a of a stopper 7 between a feed roller 5 and a pressure roller 6. Then the pressure roller 6 is moved inward and the slip 2a is held between both rollers 5, 6 because the contact point between these rollers 5, 6 is located above the L-shaped block 7a. If the stopper 7 is allowed to slip to the left by clamping the pressure roller 6, the slip 2a, left as it is between the rollers 5, 6, can be fed downward, thus achieving pre-arranged printing.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present BA relates to the structure of a front inserter, which is one type of 7-ohm handling serial printer.

[Conventional technology]

Conventionally, the front inserter mainly has the function of inserting copy slips into the printer one by one, sucking in, printing, and ejecting the slips, but in order to successfully insert the slips into the 70-note inserter, there are restrictions on the medium (slip). ' is usually present. Particularly in the case of copy slips, the edges are glued so that the edges of the slip can be properly placed on the opening/closing part between a pair of opposing rollers.

Since the slip is usually inserted from the top, the bottom edge of the slip should be
It is necessary to attach the

[Problems to be solved]

However, the top edge of a slip that is not designed for use with a 70-note inserter is usually glued.

In this case, there was a problem in that it was extremely difficult to bring the slip to the opening of the feed row 2 of the front inserter because the lower end was disjointed.

Solution to problem c] The present invention solves the above problem, and when a printing paper having a glued end is inserted, the end comes into contact with a retractable stopper and is temporarily stopped. In the front inserter, the end portion is sandwiched between a pair of rollers 2 and fed to perform predetermined printing, and the stopper is a two-foot roller located above and below the pair of rollers, respectively. This is a book with a structure that includes:

(Example〕 Next, the embodiment will be described with reference to FIGS. 1 to 3.

FIG. 1 is a perspective view of a main part of a front inserter according to the present invention, and FIGS. 2 and 3 are side views showing states in which a slip is inserted into the front inserter from above and below, respectively.

In the figure, the printer's 70 nt inserter is located at upper guide 1.
and lower guide 11 (respectively, see Fig. 2), platen 3 and card holder 4 (second norm) arranged opposite to each other in the center.
) and four sets of feed rollers 5 arranged oppositely below it.
(See Fig. 2) and the pressure roller 6 and a pair of left and right stoppers 7.8 (
(having tip-shaped portions 7a and 8a, respectively).

Here, the L-shaped portion 7a of the pair of stoppers 7 on the left in FIG.
are arranged corresponding to the lower side of the pressure roller 6, and the L-shaped portions 8a of the right pair of stones/rings 8 are arranged corresponding to the upper side of the pressure roller 6. Also, each stopper 7.8
are swingable about their respective lower portions as fulcrums, but usually the L-shaped portions 7a, 8a are located at positions that block the gap between the openings and the lugs 5, 6, respectively.

Next, the operation will be explained. First, the case where the slip 2a with its lower end glued in FIG. 2 is inserted into the front inserter from above will be explained.

In FIG. 2, the slip 2a with its lower end glued is guided by the guide 1 in the left half of the front inserter in FIG. 1 and inserted from above. The slip 2a passes between the card holder 4 and the grating 3 as shown in FIG. 2, and then rides on the L-shaped portion 7a of the stopper 7 between the feed roller 5 and the pressure roller 6 and stops.

Here, the pressure roller 6 is moved inward. Then, since the contact point t-j of both rollers 5 and 6 is located above the L-shaped portion 7a', the slip 2a is sandwiched between both ends -25 and 6. Therefore, here the pressure roller 6
If you clamp the stopper 7 and release it to the left in Fig. 2,
The slip 2a remains sandwiched between the rollers 5 and 6 as described above, and can be fed downward, and predetermined printing is performed.

Next, Figure 2 shows the slip 2b with the upper end glued from the bottom.
In this case, insert . This transmission M2bt-1° is inserted from the lower front of the printer along the guide plate 11 at the right hand side of the 70-point inserter in FIG. The inserted slip 2b is stopped by the L-shaped portion 8a of the stopper 8, which in this case is located below the reed-setting L-shaped portion 8a of the side roller 5.6. Therefore, when the roller 6 is moved and clamped, the slip 2b is sandwiched between the rollers 5 and 6. Therefore, after the stopper 8 is released, the slip 2b can be fed upward.

By slightly changing the height position of the stoppers 7 and 8 on the left and right sides of the front inserter, two types of slips can be used with the front inserter having the same groove bottom.

The sensors 12, 13 (see FIG. 1) detect which guide 1, 1'1 contains the slips 2a, 2b, and specify the feeding direction of the slips.

〔Effect of the invention〕

As explained above, in the present invention, in the same front inserter, the stoppers for stopping the paper are of type 2N, and one is placed below the row 2 and the other is placed above the roller, so that the lower end When inserting a slip with adhesive, it is inserted from above and brought into contact with one of the stoppers, and when inserting the upper end adhesive slip 2, it is inserted from below and brought into contact with the other stopper. The ends of the slip are properly sandwiched between the rollers, allowing for smooth insertion and feeding of the slip, which has the effect of improving reliability and hanging.
