Description

[Detailed Description of the Invention] Technical Field of the Invention The present invention relates to a form processing device equipped with an optical character reading device, etc., in which a form that moves along a sheet guide is processed by a reference surface provided on one side line of the sheet guide. The present invention relates to a method for aligning forms that are conveyed while being brought into contact with the paper.

(B) Background of the technology In order to read each glaze data recorded on a large number of forms one by one and record it on a magnetic tape of a storage device, a form processing using an optical character reader is used. . FIG. 1 shows a general configuration of such a form processing device. A large number of forms 2 are stored in a hopper section 1. The documents sequentially fed out from the hopper section 1 are separated one by one by the separator section 3. Each separated form is conveyed along the conveyance path and is centered in the aligner section 4 so as to be aligned with the reading reference surface. The data of the form traveling at a constant speed while resting on a reference surface is read by a reading section 5 consisting of an optical character reading device. The read data is input to a storage device (not shown) and displayed on a monitor television (not shown). The IIIB format that has been read is printed in the serial numbering section 6 as required. Bladder enlargement,
The printed forms are sorted by the gate 7 to the first passage 8 or the second passage 9, and are transferred to the first stacker section 10 or the second stacker section 9, respectively.
It is transported into the stacker section 11 and stored there.

Reference numeral 12 denotes a document passage detection sensor. 7. A method of forcibly transporting the form in the direction of the reference surface using rollers and bringing it into contact with the reference surface; or 7.
A method is used in which the form is brought into contact with a reference surface using a form claw at the 21st part, and the form is conveyed again. However, in the former method, it is necessary to provide an obliquely arranged rotating shaft, which makes the arrangement of the drive system or drive power transmission system complicated and disadvantageous in relation to other drive systems. In the method described above, the driving of document conveyance is stopped fl+l
It is troublesome to control the I control and the operation of the aligner claws, and also requires a large and complicated mechanical structure.

(To) Object of the Invention The present invention was developed in view of the above-mentioned drawbacks, and it is an object of the present invention to easily bring a document that is being moved in an aligner into contact with a reference surface using a mechanism with a simple structure. An object of the present invention is to provide an aligning device for aligning forms.

(G)) Structure of the Invention An object of the present invention is to move the form along upper and lower sheet guides that regulate the conveyance direction of the form by means of a conveyance means for conveying the form, and to An aligning device light for one square sheet that is conveyed while being in contact with a reference surface provided at one side end of the guide, wherein the upper and lower sheet guides are moved from the reference surface in a direction perpendicular to the conveyance direction of the form. This is achieved by providing a form aligning device characterized by the following features:

(2) Embodiment of the Invention FIG. 2 is a diagram for explaining an embodiment of the aligning apparatus according to the present invention. FIG. 3 is a sectional view of the aligning device viewed from the direction of the arrow (indicated by symbol A in the figure) shown in FIG.

In the figure, the form 2 is guided by an arrow (-Q
(shown as B).

A guide wall 13 is not provided along one side line of this conveyance path,
The surface of this guide wall 13 on the conveyance path side becomes a reference surface 13a.

The upper and lower sheet guides 14 and 15 constituting this conveyance path have a truncated cone shape that curves away from the reference surface 13a.

Further, two conveyance rollers 16 are provided along the conveyance surfaces of the upper and lower sheet guides each having a truncated cone shape.

With the above-described configuration, the form 2 is moved in the direction of the reference surface 13a (
It receives a force (in the direction of the arrow shown by array B in the figure).

This is because the form 2 conveyed by the feed roller 16 passes over the H frustum-shaped sheet guide 15 when it reaches the curved part of the upper and lower sheet guides 14 and 15. It is conveyed obliquely in the direction of the surface 13a. Due to the rigidity of the form 2, the left corner comes into contact with the upper sheet guide 14 and receives a restricting force in the conveying direction of the form 2.

At this time, no regulating force acts on the right corner of the one-limit slip 2 that is not in contact.

Therefore, force is applied to the form 2 in the direction of the arrow (indicated by -QA in the figure). However, the two transport rollers 16a, 1
6b in the direction of arrow A to convey form 2. 2 does not move but moves in the direction of the arrow (indicated by symbol B in the figure). Tsut
When the form b 2 passes through a conveying surface composed of upper and lower sheet guides 14.15 that move away from the reference surface 13a, it is conveyed in contact with the reference surface 1.3a and the reference surface 13a.

Next, other embodiments of the present invention will be described.

5 and 6 are diagrams for explaining other embodiments of the document aligning device according to the present invention. In FIG. 5, 14 and 15 are provided upward in a direction away from the reference surface 13a. The upper and lower sheet guides 16 are conveyance rollers that are provided at positions apart from the reference surface 13a by a distance shorter than half the length in the width direction of the document to which the document 2 is to be conveyed.

Description of the same parts as in FIGS. 3 and 4 will be omitted.

With the above-described configuration, the form 2 is passed between the upper and lower sheet guides 14.15 that are provided upward in a direction away from the reference surface 13a, so that the form 2 is aligned with the reference surface due to the inclination of the upper and lower sheet guides 14.15. It receives a force in the direction 13a (in the direction of the arrow indicated by symbol B in the figure).

This is because the form 2 is conveyed by one conveyance roller 16 provided at a position away from the reference surface 13a by a distance shorter than half the length of the form in the width direction.
) is subjected to a rotational force in the direction shown in ).

However, form 2 has upper and lower 7'-toe guides 14°1
5 is provided facing upward, it receives a force that tends to move toward the reference surface 13a when being conveyed.

Therefore, the form 2 cancels out the rotational force of one conveyance roller 16 in the direction of the arrow A, and moves in the direction of the arrow (71 in the middle symbol B).

When the form 2 passes between the upper and lower sheet kites 14 and 15, which are provided upward in the direction away from the reference surface 13a, it moves obliquely toward the reference surface 13a.
□After passing through the conveyance roller 16, the sheet contacts the reference surface 13a and is conveyed.

(G) As described in detail, according to the present invention, a form can be brought into contact with and aligned with a reference surface using a simple structure in which the upper and lower sheet guides are simply curved in a direction away from the reference surface. Aligning creates a sharp edge.
