PROBLEM TO BE SOLVED: To provide a paper feeding device having a simple configuration and capable of reducing a carrying load when carrying recording media. SOLUTION: When a recording medium P is carried by both a feeding roller 10 and a carrying roller 13 so as to gradually reduce the curvature of the recording medium P, the feeding roller 10 is separated from the recording medium P via a paper feeding arm 33 due to action of an actuator 50. Therefore, pressure pressing the recording medium P by the feeding roller 10 is gradually reduced, and a carrying burden of the carrying roller 13 is gradually reduced. COPYRIGHT: (C)2007,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a package material causing no jam in a paper carrying passage, even if a printer performs paper feeding operation in a state of installing the package material in the printer regardless of the existence of storage of paper. SOLUTION: A downstream side edge part 51 in the paper carrying direction of a side plate B44 abuts on an end surface 22a of a guide member 20 when the side plate B44 tries to move to the downstream side in the paper carrying direction. Thus, the movement to the downstream side in the paper carrying direction of a bottom plate 43 connected to the side plate B44 is regulated. COPYRIGHT: (C)2007,JPO&INPIT

PROBLEM TO BE SOLVED: To provide an image forming device capable of effectively suppressing double feed of paper and reducing the number of components. SOLUTION: In this image forming device (thermal transfer printer), a control part 26 controls drive of a paper feeding motor 17 to carry paper 9 in the state where the paper 9 is pressed by a feeding roller 4 and a press roller 6. The control part 26 performs control such that a push-up member 14 is vertically rotated by driving a push-up member drive motor 18. In addition, after feeding the paper P by rotating a paper feeding roller 10 in the arrow C direction in the Figure 14, the control part 26 carries the paper 9 by 10.6 mm to the direction reverse to the paper feeding direction (the arrow Y direction in the Figure 15), by rotating the paper feeding roller 4 in the arrow E direction in the Figure 15 while lifting up the push-up member 14. After that, the control member 26 performs control so as to lower the push-up member 14. COPYRIGHT: (C)2007,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a recorder in which the footprint of its body is made to be a size approximately equal to an area of a recording sheet storage section and a united cartridge containing the recording sheet and an ink sheet can be loaded to the recorder without increasing the footprint of the body. SOLUTION: This recorder is constituted such that the cartridge 10 having the recording sheet storage section 2 can be detachably loaded to the recorder. The recorder is equipped with a sheet rotating means for rotating a recording sheet 5 around a shaft provided in parallel to a normal direction of the recording face when feeding the recording sheet 5 to an image forming section 20 from the cartridge 10. The longitudinal direction of the stored recording sheet is roughly perpendicular to the longitudinal direction of the recording sheet at a time when the recording is performed thereon on the image forming section 20.

PROBLEM TO BE SOLVED: To provide a feeder reliably preventing double feed of printed paper sheets. SOLUTION: A retard roller 13 for separating a paper sheet P1 at the highest position and second and subsequent paper sheets P2 to be fed by nipping the paper sheets between the feed roller 12 and the retard roller, and a guide face 10b for guiding a tip of the paper sheet to the downstream side are provided in the position opposing the feed roller 12 to feed the paper sheets. A recess 10d is formed in the guide face 10b, and after the tip of the paper sheet P1 at the highest position passes through a nip point between the feed roller 12 and the retard roller 13, a tip 14b of a return lever 14 is controlled to be located at the recess 10d. Thus, even when the tip of the second paper sheet P2 passes through between the feed roller 12 and the retard roller 13, the tip is abutted on the tip 14b of the return lever 14 to reliably prevent double feed of the second paper sheet P2.

PROBLEM TO BE SOLVED: To remove a jamming sheet easily. SOLUTION: An inverted transport device 13 for sheets is equipped with a U-turn path 13b having an approximately U-form inner side wall 13b2a for inverting in guidance a sheet fed from a feed hole and ejecting from an eject hole and outer side walls 13b1a and 13b3a confronting the inner side wall and an inverting main roller 13a and follower rollers 13a1 and 13a2 installed on the U-turn path 13b for transporting the sheet, wherein the outer side wall are each divided into an upstream portion 13b1a and a downstream portion 13b3a in the sheet transporting direction and supported capable of approaching and separating to/from the inner side wall. If the upstream portions 13b1a and downstream portions 13b3a are separated from the inner side wall 13b2a, the U-turn path 13b is opened to allow access for removing the jamming sheet.
