Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper setting device that sets a plurality of stacked continuously folded papers in a proper position.

Conventionally, in this type of paper setting method, as shown in FIG. The stopper 2 is released in the direction of the arrow to position the paper 1, and then, as shown in Fig. 2, the sensors 5 and 6 are used to identify the presence or absence of the paper 7, the wrong front or back, the vertical misalignment, etc. . However, with this method, there are many variations in the paper set position, and it is necessary to drive the stopper 2 in the direction of the arrow, and when using copy paper, there may be misalignment between the original paper (usually thick) and the copy paper (usually thin), etc. , the detection is unstable, and as shown in Figure 2, the paper 7
Special considerations for identification are required, such as printing a diagonal black section 7' or providing a hole 8.
It had the disadvantage of being expensive.

An object of the present invention is to provide a continuous folding paper setting device that allows easy and reliable paper setting without the need for a special paper stopper, and that can detect the paper without printing or punching for identification on the paper. The goal is to provide the following.

The present invention stably determines the set position by abutting the folds when setting the paper, and then utilizes the fact that at least one of the plurality of sheets has a notched corner. , a plurality of sensors are used to prevent mistakes such as wrong front and back sides, misalignment of upper and lower layers, presence or absence of paper, and setting errors such as setting only one sheet each.

Next, embodiments of the present invention will be described with reference to the drawings.

Referring to FIG. 3, one embodiment of the present invention includes a continuous folding sheet 15, a set plate 9 having an edge 10 at a nearly right angle, a clamp roller 11, and transmissive sensors 12 and 13.
reflective sensor 14.

The first fold 15' of the continuous folding paper 15 is
In the direction of the arrow as shown in FIG.
The paper is positioned by pressing lightly, and then the clamp roller 11 is operated to set the paper at that position, ensuring reliable positioning.

Next, referring to FIG. 5, the top right corner of the front paper 15a of the continuous folding paper 15 used in this embodiment is cut out as shown in FIG. 5, and the thin paper 15b for copying is cut out. Complete paper is used.

The transmission type sensor 13 does not work with the thin copying paper 15b (detects the transmitted light), but detects the original paper (thick) 15a because the amount of light transmitted is small. Paper (thick) 15a or copy paper (thin) 1
5b can also be detected. The reflective sensor 14 shines light onto the paper and detects its reflection, so even if the original paper 15a is used, the copy paper 15
It can also be detected by b. The three sensors can detect and discriminate all possible combinations, such as wrong front and back sides, vertical misalignment, misalignment between original paper and copy paper, etc., as shown in FIG. In FIG. 6, in the sensor state section, ◯ indicates detection, × indicates non-detection, and parentheses indicate the case where the front and back sides are reversed.

For example, considering the set state of FIG. 5 as an example, since there is a copy paper 15b to the sensor 12,
“Dot” (〇), sensor 14 has no paper, so “no” (x), and sensor 13 has both original paper 15a and copy paper 15b, so “dot” (〇), which indicates a normal setting. be. For example, if the copy paper is shifted downward, the paper 12 is "None" (X) and the sensor 13 is "A".
(〇), the sensor 14 becomes "none" (x), and misalignment of the copy paper is detected.

As explained above, the present invention includes a continuous folding sheet in which at least one of a plurality of sheets has one corner cut out, a fold abutting section, a clamp mechanism, and a plurality of sensors. It is effective in detecting and preventing setting errors such as the wrong front and back sides of paper, misalignment of upper and lower layers, presence or absence of paper, and setting only one sheet each.

Claims (1)

[Claims] 1. A first sheet of paper having a notch at the tip of one side edge, and at least one second sheet of paper having a light transmittance higher than that of the first sheet of paper. a set plate having a surface on which the continuous folded paper moves, and the first paper and the second paper set on a line parallel to the surface and perpendicular to the moving direction of the continuous folded paper. a first detection means for detecting that a first side edge of at least one of the first sheets of paper or a second sheet of the first paper and the second paper is located on the line; a second detection means for detecting that a side edge of at least one of the first paper sheet and the second paper sheet is located near the line on the moving direction side of the continuous folded paper sheet; the first side edge and the second side edge;
