Patent number: 7284752Abstract: A sheet post-processing device of the present invention includes a jam-disposal mechanism for moving a moving section which is provided opposite to a staple tray to the outside of the device. That is, in the sheet post-processing device, since a portion of the moving section can be moved to the outside, it is possible to form a space in front of the staple tray. Thus, it is easy to perform the jam-disposal by using the space. Further, since the staple tray is not moved in forming the space, consistency of placed sheets is not lost. Further, since it is not required that a space to perform the jam-disposal is prepared inside the device in advance, it is easy to miniaturize the device. Thus, the sheet post-processing device of the present invention is a compact sheet post-processing device by which the jam-disposal can be performed without losing the consistency of a sheet bundle placed on the staple tray.Type: GrantFiled: October 20, 2004Date of Patent: October 23, 2007Assignee: Sharp Kabushiki KaishaInventors: Jinichi Nagata, Shigeki Hayashi, Kiyoshi Tokishige, Toshiki Ogita, Toyoaki Nanba

Patent number: 6708972Abstract: A plurality of bin units are provided with respective gates and, hence, it is possible to sufficiently narrow the clearance between the gates and the bodies of the bin unit. When the gate provided at each bin unit is expanded to lie toward a conveying path, the front edge of the gate becomes put into a dent portion of a sidewall of an image-forming apparatus. For this reason, any clearance or protrusion causing jamming of recording paper is not formed in a branch path extending from the conveying path to a discharged paper tray through the gate and, hence, it is possible to guide recording paper from the conveying path into each bin unit by means of the gate smoothly.Type: GrantFiled: March 4, 2002Date of Patent: March 23, 2004Assignee: Sharp Kabushiki KaishaInventors: Toshiki Ogita, Shigeki Hayashi, Naofumi Okada, Jinichi Nagata, Kiyoshi Tokishige, Toyoaki Nanba

Patent number: 6695303Abstract: A paper feeder includes: a multiple number of paper feed cassettes arranged abreast at approximately the same level in the sheet feed direction. These paper feed cassettes are formed into a unibody structure so that they can be pulled out altogether. The more upstream a paper feed cassette is located with respect to the sheet feed direction, the higher the level of the upper surface of the paper feed cassette is arranged. This arrangement affords a space over the downstream paper feed cassette, in which a feed path for recording paper picked up from a paper feed cassette located on the upstream side can be arranged.Type: GrantFiled: February 6, 2002Date of Patent: February 24, 2004Assignee: Sharp Kabushiki KaishaInventors: Naofumi Okada, Shigeki Hayashi, Toyoaki Nanba, Jinichi Nagata, Toshiki Ogita, Kiyoshi Tokishige

Publication number: 20020121734Abstract: A plurality of bin units 91 forming a bin unit assembly are provided with respective gates 97 and, hence, it is possible to sufficiently narrow the clearance between the gates 97 and the bodies of the bin unit 91. When the gate 97 provided at each bin unit 91 is expanded to lie toward a conveying path 93, the front edge of the gate 97 becomes put into a dent portion 92a of a sidewall 92 of an image-forming apparatus 1. For this reason, any clearance or protrusion causing jamming of recording paper is not formed in a branch path extending from the conveying path 92 to a discharged paper tray 99 through the gate 97 and, hence, it is possible to guide recording paper from the conveying path into each bin unit 91 by means of the gate 97 smoothly.Type: ApplicationFiled: March 4, 2002Publication date: September 5, 2002Inventors: Toshiki Ogita, Shigeki Hayashi, Naofumi Okada, Jinichi Nagata, Kiyoshi Tokishige, Toyoaki Nanba
