Abstract

PURPOSE:To enhance accuracy in transporting sheets of paper and thereby have a sheet transport device with high performance by furnishing a backup roller facing the follower roller of the transport roller in a sheet transport device for thin paper and multi-part paper, such as FAX, and by coupling it with the other transport roller on the driving side transmissively. CONSTITUTION:When a sheet 1 of paper separated at the separation part is pinched by transport rollers 19a, 19b, a clutch 15 will shut off power transmission to the shafts 9, 8. Thus the transporting force for the sheet 1 generated by the feed roller 5 and sendout roller 4 is of no effect any more. Because, at this time, the backup roller 22 in linkage with the transport roller 19a through a belt faces the transport roller 19b, the transporting force of the rollers 19a, 19b increases. Therefore, the sheet 1 is transported accurately by the transport rollers 19a, 19b even though the load resistances of the separator part, sendout roller 4 are applied to the sheet.

。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper sheet conveying device in a paper sheet processing device such as a FAX, printer, copier, automatic form processing device, etc., and is particularly effective for thin sheets and multi-part paper. This paper sheet conveying device exhibits the following characteristics.

２５および摩擦部材６によって１枚ずつに分離される。1 and 2 show an example of a conventional friction separator. That is, the paper sheets 1 are stacked on the push plate 3 via the springs 2, and are separated one by one by the feed roller 4, the feed row 25, and the friction member 6.

．． Rows 24, 5, 10a connected via 12°13
The paper sheets are rotated by the ti motor 14 so as to carry out the sheets in the same direction.

て回転される。Conveyance rollers 10a and 10b are disposed downstream of the separation section in order to convey the sheets 1 separated one by one by the separation section composed of the feed row 25 and the friction member 6 to the next process. The conveying roller 10b is pressed by a spring 16 to a conveying roller 10a disposed on a rotating shaft. Therefore, when the paper sheet 1 is not between the transport rollers 10a and 10b, the transport roller 10b is driven by the transport roller 10H, and when the paper sheet 1 is between the transport rollers 10a and 10b, the transport roller 10b is driven by the transport roller 10H. , the conveyance roller 10b is rotated through the paper sheet 1.

A clutch 15 is installed between the shafts 8, 9 and the motor 14 in order to remove the driving force of the shafts 8, 9 when they are clamped by the shafts 10b.

搬送ローラ１０ａ、１０ｂによって紙葉を次工程へ搬送
する際に搬送ローラ１０ｂと紙葉ｌとの間にスリップが
生じるため、紙葉１を正確に搬送することができない。When the sheet of paper is conveyed to the next process by the conveyance rollers 10a and 10b, a slip occurs between the conveyance roller 10b and the sheet of paper 1, so that the sheet of paper 1 cannot be conveyed accurately.

難となる。That is, when the driving force of the shafts 8 and 9 is removed by the clutch 15, the conveyance force of the feed roller 5 is disconnected. In this state, when a conveying force is applied to the sheet 1 by the conveying rollers 210a and 10b, the friction member 6 and the feeding roller 2
Frictional force moves in the part that is in contact with 5, which becomes load resistance. 11 where this load resistance increases
0a and 10b make it difficult to move the sheet 1 accurately.

くろ状になってしまう欠点を有している。In addition, when multi-part paper for printing multiple forms at the same time is conveyed at the same time, a conveying force is exerted by the conveying row and ylOa on the paper sheet that is in contact with the conveying roller 10aK.
Since the conveyance roller 10b is a driven roller, the conveyance force of the conveyance roller 10b is not applied to the paper sheets in contact with the conveyance roller 10b1, and as a result, the upper side of the multi-part paper and the lower side of the paper sheet Since the amount of movement is different between the two, it has the disadvantage that it becomes curved and bag-like.

。A feature of the present invention is that in a paper sheet conveying device, driving force is applied to both opposing conveyance rollers to accurately convey sheets without causing slippage between the conveyance rollers and the sheets. In this system, one driven-side transport roller is pressed against one of the transport rollers arranged on the drive shaft and a backup roller that provides rotational driving force to the other driven-side transport roller using a spring or the like. It is something.

Also, the conveyance force exerted on the sheet by the feed roller 24 is no longer applied. However, in the present invention, since the backup roller 22 is provided, the conveyance force by the conveyance rollers 19a and 19b increases. Therefore, even if the load resistance in the separating section and the feed-out row 24 acts on the sheet, it can be accurately transported by the transport rollers 19a, 19b.
