Description

[Detailed Description of the Invention] The present invention relates to a paper sheet conveying device provided with a transparent window plate for operator's confirmation, removal, storage, etc.

Generally, in a paper sheet conveying device, as shown in Fig. 1, after a paper sheet 1 passes through an OCR reading head section 2, recognition processing is performed, and the reading result is displayed on a display device (not shown) such as a CTR. indicate. At this time, if, for example, the document is unreadable or misread, you will be forced to compare it with the document to be read. It was necessary to make corrections and move on to the next work process.

As a method for checking the actual document in such a case, for example, as shown in FIG. 2, there is a method in which the paper is attracted to a vacuum belt and the paper is conveyed and stopped. In more detail with reference to FIG. 2, the vacuum chamber 11 communicates with a vacuum fan (not shown), and the vacuum feed belt 2 at the front of the chamber has its suction hole 13 and The slot 14 is configured to be able to attract the paper 1, and due to this attraction, the paper 1 is conveyed along with the movement of the belt 12, and the conveyance is stopped when the belt 12 is stopped. Further, the front surface of the paper 1 is covered with a clear window 15 made of a transparent member, and this clear window 15 has a tension spring 1 attached to its lower end.
6 in the opposite direction via the fulcrum 17 and is normally closed. Therefore, the paper 1 enters the operator's eye E through the clear window 15.
When the operator takes out paper 1 and checks it,
This is done by opening the clear window 15 by tilting it in the direction of the arrow 18.

This method does not obstruct the field of view 19 when observing the paper 1 that is stopped at the visual confirmation position, and the operator does not get tired, but as is clear from the figure, the device requires a considerable number of parts. There are drawbacks that require it.

Furthermore, as shown in FIG. 3A and FIG. 3B, which is an enlarged explanatory view of arrow B in the same figure, a method can be considered in which a spring member and a feed roller are combined. To explain these figures in more detail, the paper 1 is sandwiched between the spring wire 20 provided on the clear window 15 and the feed roller 21 provided behind the paper 1, and when there is no paper 1 (see Fig. 3B), , the spring material wire 20 has entered the recess of the feed roller 21, but the paper 1
comes near the feed roller 21, the frictional force of the rotating feed roller 21 causes the spring material wire 20 to
The sheet is conveyed because the feed roller 21 is larger than that of , but when the rotation of the feed roller 21 is stopped, the sheet 1 is pressed against the feed roller 21 by the spring wire 20 and its conveyance is stopped. According to such a method, the number of parts of the device is reduced, but since the spring material wire 20 is attached to the clear window 15, visibility is obstructed and the device is exposed to sunlight.
Therefore, it was necessary to move the sheet 1 a little and reconfirm it, so that it could not be said to be perfect.

The present invention has been devised in view of these conventional drawbacks, and aims to provide a paper sheet conveying device that does not obstruct the operator's view and has a simple structure.

The present invention includes a transparent window plate member having a concave groove on the back side along the conveyance direction of paper sheets and disposed in front of the paper sheet conveyance path; The transparent window plate member is made a part of the conveyance mechanism by providing a belt or roller arranged to convey and stop the paper sheets, and the belt 2 conveys the paper sheets by rotating and stopping the rollers. - It is possible to stop.

Next, embodiments of the present invention will be described based on the drawings.

FIG. 4 is a side cross-sectional explanatory view of a paper sheet conveying device according to an embodiment of the present invention.

A concave groove 3 is provided on the back side of the clear window 31.
The clear window 31 is provided in front of the paper 1, perpendicular to the feed base 32, and with its back surface facing the guide plate 33. clear window 3
1 is fixed to the feed base 33 in the illustrated example, but as shown in the prior art of FIG.
It goes without saying that the structure may be constructed so that it can be opened and closed freely. A round belt 35 and a pulley 36 are arranged on the back side of the clear window 31. In particular, the round belt 35 is arranged at a position corresponding to the groove 32.

Therefore, the paper 1 is sandwiched between the groove 32 and the round belt 35 and is elastically biased in a direction perpendicular to the conveying direction, and when the round belt 35 is not driven, the paper 1 is held by the elastic bias. It is stopped by the pressing force. When the round belt 35 is driven, the frictional force of the round belt 35 made of a rubber member etc. is applied to the groove part 3.
2, the paper 1 is conveyed on the feed base 33 along the guide plate 34 by its driving force.

Since this embodiment is configured as described above,
There is nothing that obstructs the view when checking the paper 1 from the visual checking position, and the number of parts of the apparatus is extremely small. Note that the clear window 31 is considerably abraded due to the china clay contained in the paper 1, so for example, glass is used, and the groove portion 32 is made transparent by polishing after processing.

FIG. 5 is a front explanatory view of a paper sheet conveying device according to another embodiment of the present invention, and in relation to FIG. 4, the clear window is shown with the clear window removed when viewed from arrow V in the figure. ing.

In this embodiment, a pair of pulleys 36a and 36b as shown in _FIG .
An example is shown in which the effect of causing the feed base 33 to act on the bottom end of the sheet by etching is created by setting _H2 . Therefore, in this case, it goes without saying that the grooves of the clear window (see FIG. 4) should also be inclined in the same way.

Next, the shape of the groove of the clear window and its optical system will be considered. If the cross-sectional shape of the groove 32 has a refractive index of 1.5 as shown in Figure 6 (the clear window described below also has the same refractive index), the operator's line of sight is 45° (from the vertical plane). For example, out of the field of view A to J, D to F are totally reflected by the groove 32, and therefore, the data on the paper inside B' to G' in the figure is an area that cannot be confirmed by the operator. From this, if the groove portion 32 has a cross-sectional shape as shown in FIG. 7, total reflection will not occur and all data on the paper can be confirmed.

In the above discussion, we have dealt with the case where the operator's line of sight is 45 degrees, but it goes without saying that total reflection will not occur if the line of sight is 90 degrees.

Further, the groove portion of the present invention can obtain the same function not only by providing a recess in the transparent member as in the above-mentioned embodiments, but also by bending the transparent member.

FIG. 8 is an explanatory diagram of the embodiment, and A to H
It is totally reflected in a part of the field of view, and the data on the paper shows that the area inside B' to F' in the same figure is an area that cannot be confirmed by the operator. From this, if the bent shape is made into a cross-sectional shape as shown in FIG. 9, all data on the paper can be confirmed although there is some distortion.

Note that the shape of the groove portion of the present invention is not limited to the above-mentioned embodiment, and may be, for example, as shown in FIGS. 10A to 10D. 10th
Figure A shows the cross-sectional shape of the groove 32 with a different slope (θ
₁ <θ ₂ ) It is formed in a V-shape with a straight line,
Figure 10B shows the thickness of the upper part of the clear window 31.
The plate thickness t ₁ and the lower plate thickness t ₂ are different (t ₁ >t ₂ ), and the upper and lower parts are connected by a curved surface. 1st
Figure 0C shows the cross-sectional shape of the groove 32 with different radii.
It is formed by R ₁ and R ₂ (R ₁ <R ₂ ). In this example, if the illustrated cross-sectional shape is a spherical recess, a roller may be used instead of the round belt as the driving member. In FIG. 10D, the cross-sectional shape of the groove portion 32 is approximately trapezoidal, and a V-shaped belt 35' is used as the driving member in this case.

As is clear from the above description, the paper sheet conveyance device according to the present invention is constructed by incorporating a transparent window plate member into a part of the conveyance mechanism, so that the operator can completely visually check the paper sheets. , and the number of parts is significantly reduced compared to the conventional one.
