[0047] Next, the structures of the driving roller 26 and the driven roller 30 according to the first embodiment of the present invention will be described with reference to FIGS. 7 to 10 .

[0048] Figure 7(a) shows an enlarged perspective view of a driving roller and a driven roller according to a first embodiment of the present invention, and Figure 7(b) shows a front view of a driving roller and a driven roller according to a first embodiment of the present invention In the figure, the supporting frame 32 is cut off to cover a part of the driven roller shaft to clearly show the shaft portion of the driven roller. As shown in FIG. 7( a ) and FIG. 7( b ), the driving roller 26 and the driven roller 30 cooperate as main parts constituting the paper discharge device of the present invention. The driving roller 26 is placed on the upper side of the driven roller 30 and is fixed on the driving roller shaft 41. The driving roller shaft 41 is perpendicular to the paper discharge di...

[0061] Fig. 11 (a) shows the perspective view of the driven roller according to the second embodiment of the present invention, Fig. 11 (b) shows the front view of the driven roller according to the second embodiment of the present invention, Fig. 11 (c) Shown is a side view of a driven roller according to a second embodiment of the present invention. Here, the same reference numerals are used for the same or corresponding components as in the first embodiment.

[0062] As shown in FIG. 11( a ), an annular groove 43 is arranged in the middle of the driven roller 30 around its axis, and the annular groove 43 divides the driven roller 30 into a left half and a right half along its axial direction. For the above-mentioned two parts of the roll section, six passage grooves are evenly distributed along its outer peripheral surface at equal intervals respectively, namely the left groove 42a and the right groove 42b. The depth of the grooves 42a, 42b is preferably the same as the dep...

[0067] Fig. 12 (a) shows the perspective view of the driven roller according to the third embodiment of the present invention, Fig. 12 (b) shows the front view of the driven roller according to the third embodiment of the present invention, Fig. 12 (c) Shown is a cross-sectional view of a driven roller according to a third embodiment of the present invention, that is, a cross-sectional view along line E-E in FIG. 12(b).

[0068] As shown in FIG. 12( a ) and FIG. 12( b ), the peripheral surface of the driven roller 30 is formed by the surface of several protrusions 44 , and the part other than the protrusions 44 constitutes a concave portion. In the axial direction of the driven roller 30, the protrusions can be divided into seven protrusion groups, each protrusion group is equally spaced in the axial direction of the driven roller 30, each protrusion group includes four protrusions, each The protrusions are arranged at equal intervals at intervals of 90° on the circumference o...

Abstract

The invention discloses a recording sheet discharge device. The device is provided with a driving roller and a driven roller which are used for discharging recording sheets, wherein the driving roller is driven to rotate, and the driven roller is butted with the driving roller to rotate. The device is characterized in that a circumference surface of the driven roller comprises a circumference surface part and a recessed part which is concave relative to the circumference surface part, the recessed part is a plurality of grooves which extend in a direction parallel to the axial line of the driven roller; and any line, which is parallel to the axial line of the driven roller, on the circumference surface passes through the circumference surface part.

Description

technical field [0001] The present invention relates to a recording sheet discharge device, and more particularly to a paper discharge device equipped in an image reading device for feeding out input paper sheets smoothly and without noise. Background technique [0002] In currently known paper discharge devices, the paper is usually discharged into the paper discharge tray by a pair of driving rollers and driven rollers that abut against each other. During the paper discharge process, the driving roller is used to drive the driven roller to rotate, and the front end of the paper enters the abutting part of the driving roller and the driven roller from the upstream side, and then the paper is sent out along the conveying direction until the rear end of the paper leaves the abutment. Then, the rear end of the paper is pushed, and the paper is further moved downstream to be finally discharged (this process is referred to as discharge or discharge hereinafter). [0003] Japane...
