Description

[Detailed description of the invention] (Industrial application field) This invention is an optical character reader (hereinafter referred to as OCR)
This is related to the hopper part.

(Prior Art) A conventional hopper device such as OCR will be explained based on FIG. In FIG. 8, reference numeral 1 denotes a U-shaped paper running path, in the middle of which there is a reading section 1a for recognizing characters on the paper 2.

A hopper 3a is arranged at one end of the paper running path 1 and stores the paper 2. 4 is a slide table which can be pulled out and used when the vertical dimension of paper 2 is long. A fixed table 5 constitutes a part of the hopper 3a. 6 is a gap between the fixed table 5 and the slide table 4. A paper separating roller 7 is provided at one end of the paper running path 1. A feed roller 8 conveys the paper 2 in the paper running path 1 toward the stacker 9. Reference numeral 10 denotes a light source that illuminates the paper 2 in the reading section 1a of the paper travel path 1. 1
Reference numeral 1 denotes an image sensor that reads characters written on paper 2 through a lens 12.

Next, to explain the operation of the above structure, the slide table 4 is movable in the direction of the arrow 13, and when the paper 2 is long, it is in the pulled out state (the eighth
Figure). Next, the paper 2 is inserted into the hopper 3a, picked up by a push roller (not shown), separated by a paper separation roller 7, and separated into a paper traveling direction path 1.
The sheet 2 is transported to a reading section 1a in the reading section 1a, and the sheet 2 is illuminated by a light source 10, and the reflected light is sent to an image sensor 11 via a lens 12. The characters written on paper 2 are recognized by the controller.

When the recognition is completed, the paper 2 is discharged to the stacker 9 by the feed roller 8.

(Problem to be solved by the invention) However, in the device with the above configuration, a gap 6 is created between the slide table and the fixed table, so when the paper is set, the paper gets into this gap, causing folds and tears, and making it difficult to read. There was a problem that it became impossible.

The object of this invention is to eliminate the above-mentioned problems such as paper folding when setting paper, and to provide a compact hopper device with excellent operability and paper protection properties.

(Means for Solving the Problems) A feature of the present invention for achieving the above object is that in a hopper device that supplies paper to a device that processes the paper, the hopper device has a fixed table and a a slide table that is movable in the running direction of the paper, engages with the fixed table, and extends the longitudinal length of the paper to match the longitudinal length of the fixed table; The hopper device is provided with one elongated notch, and a guide that enters the notch is formed at one end of the fixed table on the paper insertion side in the longitudinal direction.

(Function) In the above configuration, the paper moves from the slide table toward the fixed table. At the boundary between the slide table and the fixed table, a guide formed at one end of the paper insertion side in the longitudinal direction of the fixed table is inserted into the notch of the slide table. prevent it from getting in between.

Therefore, the paper will not get stuck between the slide table and the fixed table and cause a jam, and the object of the present invention can be achieved.

(Example) An example of the present invention is shown in Figs. 1, 2, and 3.
This will be explained based on FIG. 4, FIG. 5, and FIG. 6. Fig. 1 is a plan view showing an embodiment of the present invention, Fig. 2 is a right side view of Fig. 1, Fig. 3 is a sectional view taken along line A-A' in Fig. 1, and Figs. 4 and 5 are FIG. 6 is a perspective view showing one embodiment of the present invention, and is a detailed view illustrating the effects of the present invention.

In FIG. 1, 3b is a hopper showing an embodiment of the present invention, 14 is a slide table, and therein is a long notch 15. 16 is a fixed table, and a guide 16a that enters into the notch 15 is provided. 1
Reference numeral 7 denotes a guide, which is fixed to the end of the fixed table 16 (or the guide is constructed by bending the end of the fixed table) and holds the slide table 14. direction).

A magnet 19 is fixed to the fixed table 16 and locks the slide table 14 when the slide table 14 is pulled forward.
(Figures 2 and 4) 20 is a magnet that is fixed to the fixed table 16 and acts as a lock when the slide table 14 is pushed backwards (Figure 5).

Next, to explain the operation of the above structure, the slide table 14 is moved in the front and back direction (arrow 1) by the guide 17.
If the paper 2 is shorter than the fixed table 16, as shown in FIG.
The hopper 3b can be made smaller by pushing it in until it is locked into the magnet 20. If the paper 2 is longer than the fixed table 16, the slide table 14
pull it out until it locks into the magnet 19 (Fig. 4).

Next, the paper 2 is inserted into the hopper 3b. At this time, as shown in FIG.
Therefore, fixed table 16 and slide table 1
It is inserted into the hopper 3b without entering the gap 6 of 4. The paper 2 accommodated in the hopper 3b is separated into one sheet, read, and then stored in a stacker, as in the conventional example.

Incidentally, instead of bending the end of the guide 16a provided on the fixed table 16, a block 16b that fits into the notch of the slide table may be provided at the end of the fixed table 16, as shown in FIG.

(Effects of the invention) As explained above in detail, according to the invention,
By providing a long notch in the slide table part of the hopper and providing a guide in the fixed table that fits into this notch, paper will not get stuck in the gap between the slide table and the fixed table when inserting the paper into the hopper. Because it can be accommodated, there is no paper folding or tearing, and it can be expected to be compact and have excellent operability and paper protection.

Further, since the present invention can be applied to a device having a hopper and a paper running path, it can also be used in facsimile machines and the like.
