P, the component has a depressed portion, the suppressed portion selectively contacts the connection 8 1337939 to load the suppression; the correcting member corrects the medium deflection, and the suppressed portion and the corrected portion are further There is a correction correcting portion, wherein the rectifying portion is located at both end portions of the correcting member, and the rectifying portion is a bump. The restrained portion can also be a groove. The suppressing member has a _ suppressing end which has a fixed end with the depressed portion == the fixed end is connected to the adjusting structure. The modulation, the β structure includes a stud having at least two positions that differ in position. ° The suppressing member is an elastic body, and the elastic body may be a torsion spring or an elastic sheet. The actuating member is a compression spring. The rectifying part and the medium are connected to the plane as a plane to better compensate and align. After adopting such a structure, since the elastic member is provided between the driving wheel and the correcting member, when the leading edge of the medium reaches the hybrid moxibustion system, the elastic device is separated from the restrained portion, and the correcting member will be under the action of the elastic member. When the driving wheel rotates, the resistance of the correcting member to the medium disappears, and the transmission of the medium can be avoided. Moreover, since the elastic means is provided on the frame, it can cooperate with the restrained portion on the correcting member, so that in the process of correcting the deflection of the medium, the correcting member is in a stationary state, and the effect of correcting the skew can be better achieved. Since at least two protrusions are arranged on the frame, the deflection of the medium of different thickness can be corrected by pressing one end of the torsion spring at different protrusions. [Embodiment] The present invention is further described in detail in the following, and in conjunction with the accompanying drawings: It is a sweeping and arranging mechanism towel _ The first-solid medium deflection corrects the ambiguity, including stacking in The medium in the tray 210 is defective. At the beginning end of the feed path of the media, a pick-up roller 23〇 is taken, and the pick-up roller 23 取出 removes the pick-up from the feed tray 21 and feeds it into the medium conveying path. The difference is fed by the feed roller 220 along the transport path 243 in the F direction. The main wheel 246 and the driven wheel 247 are read, scanned by the scanning module 200, and finally the scanned medium is sent out to the output tray 2 (9) by the paper discharge roller 250. The transmission path 243 is provided with a driving wheel 246 and a driven wheel tearing, and a correcting member 251 connected to the driving wheel 246. Referring to FIG. 2, the drive shaft 245 is disposed on a scanner frame. The drive wheel 246 is fixed to the drive pump 245 and is driven by a motor (not shown). The driven wheel 247 is located on the drive wheel 246. The lower side is rotated relative to it to form a clamping gap (nip) for clamping the medium and transmitting it. The correcting member 251 is mounted on the drive shaft 245 and rotates about the drive shaft 245 as an axis, and is located outside the drive wheel 246 at the position of the frame 241. A compression spring 252 is sleeved on the drive shaft 245 and between the correcting member 251 and the main wheel 246, so that the two ends of the compression spring 252 are closely connected to the connecting end surface 257 of the correcting member 251 and one end surface of the driving wheel 246. 10 1337939 Thus, when the driving wheel 246 is rotated in the paper feeding direction, due to the connection relationship of the three, the correcting member 251 is caused to directly rotate by the compression spring 25S to rotate in the same direction as the main wheel 246. The deflecting member 251 is sleeved on the driving shaft 245, and has a correcting position and an uncoupling position. wherein the correcting position is due to the convex portion 3 on the outer surface of the adjacent connecting end surface of the correcting member 251, and the correcting portion 255 is perpendicular to the direction The angle # of the leading edge of the media 成 is at a right angle. At this time, the restrained portion 256 protruding on the correcting member 251 can be in contact with a suppressing torsion spring 253 # a restraining end 267 to load and suppress the correcting member. 25 control of the correcting member 251 转动 method rotates with the driving wheel. Referring to Fig. 3, the position of the correcting portion is located near the connecting end face π of the correcting member 25A, and the depressed portion is close to the free end surface 258 of the correcting member 251. At the same time, the torsion spring 253 is located on the protrusion 264 of the frame body 241. There are three adjustment powers in the frame body 241, and _ can be convex, respectively 26 262, 263. The torsion spring has two functional ends, including a fixed end 266, which is placed in the adjustment gear position, or the slot 261 or the following, depending on the thickness of the medium. In this embodiment, the fixed end (10) Abut against the projection 262 as a gear position. The restraining end of the twisting 253 is in contact with the restraining portion 256 on the correcting member 251 and appropriately abuts against the depressed portion to generate a function of preventing the correcting member from continuing to rotate with the driving wheel 246. . In this way, the correcting unit 255 can be made to perform the correcting and biasing function. Referring to FIG. 4, during the paper feeding process, the revolving spring 251 is driven by the driving wheel ice through the (4) spring 1337939 252 to start the rotation of the torsion spring (10) _26 = (4) the 自由 256 is erected by the frame portion of the free end 2551 is sent f ' When the rotation is stopped, even if the deviation of the correction quality is skewed, the feed is called if the groove surface of the conveyed design is added. At this time, when the action: the octagonal ^ touches the plane 4 Μ of the correcting portion 255 and the driving wheel 246 in the rotating force is insufficient to make the correcting member 251 overcome the spring state of the torsion spring attack, but the fM is still in Under the action of the feed roller - continue to operate 2 - so that the medium will gradually form - the bending part, please refer to Figure 5, until the quality of the field is completely affixed to the surface of the correction section, then the deviation is achieved. The slanting is positive, and in the following process, the driving force of the medium _ 偏 255 is gradually increased, and the force applied by the driving wheel to the correcting member 251 is also increased with the gradual deformation of the pressing spring, when the driving wheel 246 is introduced. When the common force of the deflecting member M1 is increased to be larger than the torsion spring 253 of the frame body 241 to the rail top elastic force of the correcting member 251, the correcting member 25U starts to rotate, and the medium M is continuously operated by the feed roller 22〇. The leading edge will always be aligned with the correcting portion 255. Referring to FIG. 6, when the correcting member 251 is rotated by a certain angle, the leading edge of the medium M reaches the clamping gap of the driving wheel 246 and the driven wheel μ? The restraining end 267 of the 253 is just separated from the restrained portion 256 on the correcting member 251, and the correcting member 251 Under the action of the compression spring 253, the rotation of the driving wheel 246 continues. Referring to FIG. 7, the resistance of the restraining portion 256 on the correcting member 251 to the leading edge of the medium disappears. At this time, the correcting member 251 is The correcting position is turned to the release position', and the driving wheel 246 and the driven wheel 247 have corrected the deflection by 12 to h. The reaching of the scanning unit 200' can also prevent the correction of the medium by the correcting member 251. The heart correcting member 251 The rotation 'when the restrained portion 256 is again held by the torsion spring 253 ^ end 267, it begins to correct the deflection of the next f 。. See also @ 8, 9, which is the (four) two age type and The first embodiment is different in the structure of the correcting member 283, and the other portions are identical in structure; in the second embodiment, the ten-biasing member 283 is provided with three depressed portions (10), (9), and three corresponding to the three= a correcting object, (1), 112; when the opposite-fourth (four) skewing portion 100 is placed against the twisting 253 suppressing end 267, the correcting portion 110 _ end corresponding to the suppression is just in the transmission path plus, in the small After the correction of the mass deviation, the restrained portion 1〇1 is subjected to the twist (10): from the corresponding correcting portion (1) The end is just in the transmission path, and then the correction is made. The media is skewed. The need for Wei_Yes, the (f) of the f-biasing mechanism is not applied to the paper machine of the sweep = f can be used for printing Table machine, automatic feeder, photocopying machine, etc. and both the month b is used in the early paper feeding mechanism, and can also be used in the double-sided paper feeding mechanism. The medium L sheets can bear the likes and the like. The suppressing portion 256 is in the form of a -bump, which is in contact with the torsion of the twisting and attacking, and the suppressing portion 256 can also be a groove design, and the twisting ridge can suppress the (four) two or two concave projections, and the same can be suppressed. The rotation of the member 251 can also be combined with the force of the torsion of the 246-way (10) correcting member 251p to release the suppression, that is, the same effect as the bump/in the case of the present invention. The end can be two, the π-spinning spring can also be a shrapnel, which is end-ridged on the frame body, and the other: the restrained part on the partial piece is combined with the other, and can also be other elastic members. It can be set as needed. For example, the above is also the equivalent of the four. The job is that the transformation structure design similar to the above is falling within the scope of this issue.
