According to said structure, shown in Fig. 4 and 6A, from paper feeding to the leading edge P1 retained part N1 between impact drives roller 19 roller sections and the driven voller 20 roller sections at first of the file P that carries of upstream side, N1.Retained part N1, the paper feeding of the most close driven voller that the is obliquely installed 20 roller sections of N1 are to the upstream side of (Fig. 6 A), and in fact at the leading edge P1 of multiple spot place contact file P, consequently impact is very little.Therefore, when file P by conveying roller 21a, 21b supplies with and by read point 23a, and the leading edge P1 of file P collision retained part N1, during N1, can greatly reduce to impact (intake resistance of leading edge P1).Very little impact can not produce the phenomenon that advancing of file P temporarily stops or file P is crooked at read point 23a place.Therefore, can not be created in the problem that read point 23a place image reads data distortion, read operation thereby can stably keep.
In the embodiment shown in Fig. 6 B, driven voller 20 roller sections are symmetricly set on the both sides of line of centers O, and axis 20a is obliquely installed, so that near the driven voller 20 roller sections of line of centers O be positioned at paper feeding to upstream side, and away from the driven voller 20 roller sections of line of centers O be positioned at paper feeding to the downstream.
In the embodiment shown in Fig. 6 C, near the driven voller 20 roller sections of each side of line of centers O be positioned at paper feeding to the mode of upstream side be obliquely installed.Away from the axis 20a of the driven voller 20 roller sections of line of centers O perpendicular to paper feeding to (X-axis line direction), promptly be parallel to the Y direction setting.
The advantage that embodiment shown in Fig. 6 B and the 6C has is: can be reliably the leading edge P1 of file P be fixed on double-type retained part N1 place, even and hour still can form a contact form in the width W 1 of file P, as at the embodiment as shown in Fig. 6 A.
As another embodiment, driven roller 19 can be merged into one or two roller section of extending with continuous length, and a plurality of driven voller 20 roller sections can be arranged to oppress at certain intervals described one or two roller section along Y direction.As selectable scheme, can a loaded member 33 be set for each driven voller 20 roller section, so that these driven voller sections of individual drive.
In addition, on driven voller 20 roller sections, only the axis 20a of 20 1 roller sections of driven voller can be the same with the principle of described embodiment, towards paper feeding to upstream side or downstream be obliquely installed.
Be arranged on respect on symmetrically arranged each the axis 20a in document width center because driven voller 20 roller sections are loaded the loaded member 33 that makes it to contact with driven roller 19, therefore, can reduce the quantity that the position is set of loaded member 33, thus can cost-cutting.
If form agley from being positioned at the conveying roller 21a of read point 23a upstream side to the direction of bottom along the top, retained part between the 21b is to the distributing roller 19 that is positioned at read point 23a downstream, the paper feed path of retained part N1 between 20, compare when then being linearity with the paper feed path, file P can lose the rigidity of himself.Therefore, when the retained part N1 between the leading edge P1 of the file P collision distributing roller 19,20, file P may pause at read point 23a place a moment or crooked because of impacting (resistance).But, adopt said structure, then can avoid the problem as bending to take place.In addition, in Fig. 3, can make paper be arranged essentially parallel to glass board 4, leading edge P1 can be inserted in the retained part subsequently in the direction that extremely just in the path before the retained part between the distributing roller 19,20, changes paper (file P) from read point 23a.Adopt this structure, can reduce impact, can prevent that therefore the file P that transmits is crooked at read point 23a place in the holding part office.
The utility model not only can be used for the automatic paper feed device, and is applicable to the paper discharge section that is positioned at device (it can be supplied with paper (file P) one by one and read) downstream when carrying.
