摘要： PROBLEM TO BE SOLVED: To provide a sheet carrying device, capable of improving correction accuracy of a sheet, and to provide an image forming device and an image reader. SOLUTION: An inclination correcting means 2 is moved in a direction for correcting inclination of the sheet S in a state of pinching the inclined sheet S based on a detection signal from an inclination detecting means. When the inclination correcting means 2 is moved to correct the inclination of the sheet S, a guide means 111 constituting a side wall face of a sheet carrying passage 110 guiding the sheet S to the inclination correcting means 2 is also moved in the direction for correcting the inclination of the sheet S to reduce a load of the sheet S moving with movement of the inclination correcting means 2. As the load of the sheet moving with the movement of the inclination correcting means is reduced when the inclination correcting means is moved in the state of pinching the inclined sheet to correct the inclination of the sheet, the correction accuracy of the sheet can be improved.

摘要： PROBLEM TO BE SOLVED: To solve a problem that a sheet cannot be fed into a pair of resist rollers due to the lowering of separation pressure in a separation part by a loop formed on the sheet by the resist rollers in a sheet feeding device that is reduced in size without arranging a feeding roller between the resist rollers and the separation part.SOLUTION: The sheet is fed to a registration roller pair 57 by a separation-feeding unit formed of a sheet feeding roller 51 and a separation roller 53, and is made to abut on a nip of the registration roller pair 57 at rest to form a loop in the sheet. Then, when the registration roller pair 57 rotates at predetermined timing to feed the sheet, a pressurization plate 70 is raised again to bring the sheet S into press-contact with the sheet feeding roller 51 to thereby impart a feeding force to the sheet, feeding the sheet reliably to the registration roller pair 57.

摘要： PROBLEM TO BE SOLVED: To provide a plurality of branch carrying passages of sheets as recording paper sheets, for responding to a trouble occurring in one of the branch carrying passages by using the other branch carrying passage so as not to halt the device and maintain its processing capability, and for allocating a branch carrying passage suitable for a thick or thin paper sheet to implement highly accurate image formation so as to print in high quality and improve its reliability. SOLUTION: A sheet S is fed from a paper feeding cassette 209 of a sheet feeding part. Switching between a first branch carrying passage 208 and a second branch carrying passage 209 is performed by operation of a branch carrying passage switch flapper 235 to guide the sheet S to either the first branch carrying passage 208 or the second branch carrying passage 209, and then the sheet S is carried to a photoreceptor drum 13 of the image forming part. The branch carrying passages are alternately switched, for example, the sheet S is carried by the first branch carrying passage 208, and then the next sheet S is carried by the second branch carrying passage 209.
