The path for reading the image information passing through the reading reference surface is the same as the path for sending it to the stacker after reading, and the paper feed roller provided near the reading reference surface is rotated forward or backward. This is achieved by providing a conveyance mechanism for an image information reading device that uses an IF# image that the image information sheet reciprocates on the reading reference surface and is stored in the stacker.

6) Embodiments of the Invention Below, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In Figure 2, the hopper 11 is 1IkIIIR for documents etc.
It is used to store information sheets 1, and the image information sheets 1 are sequentially fed out by rotation of a big roller 12 provided on the open end side.

A stacker 13 is located on the same plane 9A as the hopper 11 and below the hopper 11.

This stacker 13 stores the image information paper 1 that is conveyed after the reading section 14 has finished reading it.

At the end of the same side of the hopper 11 and the stacker 13, an upper sheet guide 15 and a lower sheet guide 16 are stretched in parallel with an appropriate gap to form a reciprocating conveyance path 1T. This reciprocating conveyance path 17 guides the image information paper 1 so that it can reciprocate along the same path inside it, and is located below the reading section 14.
A reading reference surface 18 is provided. This reading reference surface 18
The image information paper 1 is sandwiched between an upper sheet guide 15 and a lower sheet guide 16 to remove distortion of the image information paper 1.

Two pairs of paper feeding rollers 9 are provided before and after the reading reference surface 18.
．． 10, 9', and 10' are provided. These paper feed rollers 9, 10, 9', and 10' set the image information paper 1 fed out from the hopper 11 on the reading reference surface 18 below the reading section 14, and pass the image information paper 1 through the reading reference surface 18. The image information sheet 1 is then read by the reading section 14, and after the webbing is finished, the image information sheet 1 is sent to the stacker 13 in the reverse direction.

Base end 1 of the lower sheet guide 16 of the reciprocating conveyance path 17
9 is connected to one end of the stacker 13 and guides the image information M1 after the reading is completed into the stacker 13. On the other hand, the base end 20 of the upper sheet guide 15 is bent slightly upward to form the hopper 11.
It extends towards. And -1ll of the above hopper 11
A spring piece 22 is provided on the end edge 21, and the tip of the spring piece 22 extends toward the proximal end 20 side of the upper sheet guide 15 and presses into contact with the V-face of the upper sheet guide 15. There is. This spring piece 22 is made of, for example, a plastic sheet with high mechanical strength or a metal piece, etc. 9, and the image information paper 1 fed out from the hopper 11 by the rotation of the big roller 12C) is coupled with the rotational action of the separate roller 23. The sheets are separated one by one and guided toward the reading reference surface 18 along the base end 20 of the upper sheet guide 15, and after the reading is completed, the anti-damage information is sent to the stacker 13 along the reciprocating conveyance path 1T. 1&1 is held down in the lower surface of the spring piece 22 to prevent it from flowing back toward the hopper 11.

When the spring piece 22 is made of a plastic sheet with high mechanical strength, the upper surface 24 of the separate roller 23 is formed into a rough texture to increase the coefficient of friction, as shown in FIG. The lower 1k12s is mirror-finished to reduce the coefficient of friction. In this way, the synergistic effect of the rough-textured portion of the upper surface 24 and the rotation of the separation roller 23 makes it possible to separate and feed the image information paper 1 one by one. Due to the inclination angle of 25 and its mirror finish, the image information sheet 1t discharged as shown by arrow A can be pressed as shown by arrow B, thereby preventing backflow to the hopper 11. In addition, if the spring piece 22 is made of a metal piece with a small door coefficient, such as phosphor bronze, as shown in FIG.
The same effect as above can be achieved by pasting the .

Next, the operation of the transport mechanism according to the present invention will be explained with reference to FIGS. 5 and 6. First, in order to read the damage information on the image information paper 1, as shown in FIG.

In this way, when the image information paper 1 travels at a constant speed on the reading reference surface 18 as indicated by the arrow C and the entire paper surface is read, as shown in FIG. 9', 1
0' is reversed, and the image information paper 1 is returned in the direction of the arrow within the reciprocating conveyance path 17. The tip of the image information paper 1 is
The paper collides with the spring piece 22 when discharged by the paper feed roller 9.10, but is held down as shown by arrow B by its inclination angle and smooth lower surface, preventing backflow to the hopper 11 and being stored in the stacker 13. In this way,
The image information paper 1 is sent out from the hopper 11 and sent to the reading section 14.
A series of conveyance operations are performed in which the image information is read and then returned along the same route to be stored in the stacker 13.

FIG. 7 is an explanatory diagram showing another embodiment. In the embodiment shown in FIG. 2, the image information sheets 1 are fed out one after another from the upper layer of the hopper 11, and the image information sheets 1 above the line are stacked in NIL layers on the stacker 13 from the bottom layer. It turns out to be exactly the opposite. Therefore, in the embodiment shown in FIG. 7, the hopper 11' is located below and the stacker 1
3' is positioned upward, and the image information paper 1 is fed out one by one from the upper part of the hopper 11' by the rotation of the big roller 12, and one image information paper 1 is fed out by the synergistic action of the separate roller 23 and the spring piece 22'. The paper is separated into two pieces, set on the reading reference surface 18 by two pairs of paper feed rollers 9, 10, 9', and 10', and reciprocated in the reciprocating conveyance path 17 as shown by the arrow CXD. The information sheet 1 is pushed up in the direction of the arrow E by the action of the spring piece 22', and is stored in the stacker 13' so as to be pushed up sequentially from the lower layer to the upper layer. Therefore, the image information paper 1 can be transported in exactly the same sequence. In the case of FIG. 7, the separate roller 2 of the spring piece 22'
The lower surface of 3@ has a larger friction coefficient, and the opposite upper surface has a smaller friction coefficient, so that the same effect as the first embodiment shown in FIG. 2 is achieved. In addition, in FIG. 7, the reference numeral 2T indicates that the pusher provided in the hopper 11' is a plate;
Reference numeral 28 is a suppression plate provided on the stacker 13'.

FIG. 8 is a drawing showing the planar shape of the spring piece 22' in FIG. 7. The part of the tip of the spring piece 22' that comes into contact with the top surface of the image information paper 1 is cut out in the center in the form of a strip, and tongue pieces 29 and 29 are provided on both measuring parts. Only the tongue pieces 29, 29 come into contact with both sides of the image information paper 1. In this way, when the image information paper 1 is fed in the direction of the arrow C by the rotation of the paper feed rollers 9, 1G and @', 1G', the spring piece 22 is placed in the damage prevention information writing area F. It is possible to improve the reading rate without contacting or pressing any part of the disc, and without soiling or damaging the anti-injury information entry area F.

(6) Effects of the Invention Since the present invention is constructed as described above, by reciprocating the image information paper 1 within the same reciprocating transport route 1T, the information paper 1 The image information reading device can be formed into a flat plate with a length about twice that of the image information reading device, and the conveyance path can be shortened and made small, thereby making it possible to downsize the entire image information reading device. Accordingly, the number of rollers conventionally provided at various locations along the length-transport meridian can be reduced to at least two pairs of paper feed rollers, and the cost of the entire reading device can be reduced. Further, if it is not necessary to input the rear end of the image information paper 1, it is also possible to use a pair of a-ra. Further, since the hopper and the stacker are arranged one above the other near the same side, the operator can feed and take out the image information paper 1 from the same direction, improving operability. Furthermore, since a spring piece is provided at the part where the image information paper 1 is sent from the hopper toward the reading reference surface 18, the image information paper is guided one by one to the reading reference surface 18 and stored in the stacker. Sometimes it is possible to prevent backflow to the hopper.
