Figure 1 shows the paper sheets, such as forms, fed onto the paper feed table in the paper feed section of the optical information reading device that the applicant had already submitted as a utility model registration application on July 29, 1980. This figure shows a take-out mechanism that takes out one sheet at a time. In the figure, the forms P supplied in a stacked state to the paper feed table 1 are moved so that one side edge of the form P is aligned with the reference plane 3 by moving the sheet guide 2 provided on the paper feed table 1 in the direction shown by the arrow. Available. On this reference surface side, there is a feed roller 4 that contacts the topmost form P and takes out the form P one by one, and a pick crawler that receives the form P taken out by this feed roller 4 and transports it in the direction shown by the arrow x. 5 is placed. Also,
On the side of the reference surface 3, a correction shaft 6 is provided which is pivotally attached to the reference surface 3 at one end and has a handle 6a at the other end in order to correct the warp of the form P. A rail 7 for guiding a shaft 7 and a pair of spacers 8 are provided on the 6a side, and if correction is not required when taking out the form P, the shaft 6 can be moved upward along the rail 7. It can be fixed by That is, the mechanism was such that the sheets P fed on the paper feed tray 1 were arranged with one side edge as a reference, and the sheets were taken out one by one by rotation of the feed roller 4 provided on the reference surface 3 side.

On the side of this reference surface 13, there is a feed roller 14 that rotates the top of the form P to take out the form P one by one, and a plurality of pairs that receive the form P taken out from the paper feed table 11 by the rotation of the feed roller 14. Pick crawlers 15 are arranged to grip and convey the material. Reference numeral 16 denotes a correction shaft whose one end is loosely fitted onto the shaft 23 of the feed roller 14 and has a handle 16a at the other end. It is configured such that the warp of the form P taken out can be corrected by moving the document P.

Next, the operation of the present invention based on the above configuration will be explained. In FIGS. 2a to 2c, a large number of forms P are fed in a stacked state onto the paper feed tray 11, and one side edge of the forms P is aligned with the reference plane 13 by moving the sheet guide 12 in the direction of the arrow. put. Next, the support shaft 19
The form P on the paper feed tray 11 swings around the
The weight 22 is moved along the groove 21 and fixed at a position according to the type of form P so that the top of the form abuts the feed roller 14.

At this time, the paper feed table 11 is balanced with respect to the support shaft 19 by the tension of the spring 20 in accordance with the average weight of the form P. When a document other than the average type, for example, a document P that is heavier than the average, is placed on the paper feed tray 11, the paper feed tray 11 will move downward on the take-out side (the side where the feed roller is located) due to the weight of the document P. , the take-out force F at the feed roller 14 becomes smaller. Therefore, by moving the mounting position of the heavy peg 22 to a predetermined position on the left side of the support shaft 19 (toward the front side of the paper feed tray), the take-out force F at the feed roller 14 can be made constant.

Therefore, by driving and rotating the feed roller 14, the documents P can be stably fed out one by one.

In this way, by rotating the pick rollers 15 against the form P taken out from the paper feed tray 11, the form P is held and conveyed to the subsequent process.

As explained above, according to the present invention, it is possible to stably take out paper sheets of thin thickness and special sizes (length and width dimensions of 1:2 with respect to the take-out direction), which have previously been unstable. It also has the excellent effect of being able to be used for a wide variety of paper sheets, including thick paper sheets that require a large take-out force.

Moreover, since the correction shaft is loosely fitted onto the shaft of the feed roller, the correction shaft can be removed from the form on the paper feed table, making it easier to place the form. By placing it on the paper, it is possible to prevent skew due to warping of the form.
