Patent number: 9736324Abstract: A sheet post-processing device is mounted in an image forming apparatus that includes an image reading unit and an image forming unit. The image forming unit is located under the image reading unit with a space therebetween. The sheet post-processing device includes: a first tray that is located in the space and houses a sheet ejected from the image forming unit; a post-processing unit that is located in the space and performs post-processing on a sheet in the first tray; a transfer member that, after the post-processing is performed on a sheet in the first tray, transfers the sheet to a front side of the image forming apparatus; and a second tray that is located closer to the front side of the image forming apparatus than the first tray and houses a sheet transferred by the transfer member.Type: GrantFiled: August 21, 2014Date of Patent: August 15, 2017Assignee: KONICA MINOLTA, INC.Inventors: Riichi Hama, Ryo Morita, Akiyoshi Johdai, Shinobu Seki, Naoya Nakayama, Masaki Matsui, Hidehito Kishi, Shigeki Nozawa

Patent number: 9609158Abstract: An image forming device having a printer unit, a post-processing unit, and an eject tray. The printer unit forms images on recording sheets, and the post-processing unit performs processing on a recoding sheet stack composed of one or more recording sheets output from the printer unit before the recording sheet stack is ejected onto the eject tray. The image forming device includes: a buffer unit that, while a first recording sheet resides in the post-processing unit for the post-processing, holds a second recording sheet therein, the second recording sheet output from the printer unit subsequent to the first recording sheet; and a reverse path that reverses recording sheets when the image forming device performs duplex printing. In a plan view of the image forming device taken along a vertical direction, the post-processing unit, the buffer unit, and the reverse path at least partially cover one another.Type: GrantFiled: September 16, 2015Date of Patent: March 28, 2017Assignee: Konica Minolta, Inc.Inventors: Masaki Matsui, Naoya Nakayama, Riichi Hama, Hidehito Kishi, Ryo Morita
