Publication number: 20200021694Abstract: An image forming apparatus includes the following. A measuring unit measures a physical property of media as a target on which an image is formed. An image forming operator forms an image on the media. A hardware processor controls an operation of the image forming operator and extracts a candidate of a type of media based on a measured result by the measuring unit. An operation receiver receives input to specify one type from the candidate extracted by the hardware processor. The hardware processor controls the image forming operator to form on the media an identification image determined according to a combination of the extracted candidates.Type: ApplicationFiled: June 21, 2019Publication date: January 16, 2020Inventors: Satoshi OGATA, Yumiko IZUMIYA, Kazutoshi YOSHIMURA, Tatsuhiro NOUTOMI, Sayaka OGASAWARA

Patent number: 10175625Abstract: A sheet conveying apparatus has a reference roller, a detection roller, and a detection sensor. The detection roller can move, and makes contact with the reference roller, facing the reference roller. The detection sensor outputs a signal corresponding to the displacement of the detection roller. The sheet is conveyed to a nip portion of the pair of rollers. At this time, the timing when an edge portion of the sheet being conveyed passes through the nip portion is detected. In response to the timing detected, the thickness of the sheet is detected, based on the signal output from the detection sensor.Type: GrantFiled: September 16, 2016Date of Patent: January 8, 2019Assignee: Konica Minolta, Inc.Inventors: Kazutoshi Yoshimura, Takashi Watanabe, Akinori Kimata, Shiro Umeda

Patent number: 9182722Abstract: A serial tandem image forming system is described which is capable of inhibiting both the degradation of image quality and the reduction of the productivity. This system consists mainly of the control units of upstream and downstream apparatuses. When a preceding sheet differs from the subsequent sheet in sheet type, a control unit for controlling the image forming system has the subsequent sheet stand by at a paper stop roller of the upstream apparatus, and performs the operation of switching the operating states of the upstream and downstream apparatuses in accordance with the sheet type of the subsequent sheet. Also, the control unit predicts the timing of finishing the switching of the operating state, and then re-starts the conveyance of the subsequent sheet, in advance of finishing the switching of the operating state, by controlling the paper stop roller on the basis of the predicted finishing timing.Type: GrantFiled: September 2, 2014Date of Patent: November 10, 2015Assignee: KONICA MINOLTA, INC.Inventors: Katsuyuki Ikuta, Katsunori Takahashi, Kenichi Hayashi, Kazutoshi Yoshimura, Tatsuhiro Noutomi

Patent number: 9042742Abstract: An image forming apparatus receives setting of an object to be adjusted, on an adjustment object selection screen when selecting an adjustment mode. After the object to be adjusted is set, camera(s) photograph(s) the object to be adjusted so that the image forming apparatus obtains photographed data of current object to be adjusted. Next, the apparatus searches photographed data of the object to be adjusted in the ideal state thereof from the database. Name of the object to be adjusted and related information in the photographed data agree with those of the photographed data of current object to be adjusted. The higher ranked related information is preferentially searched and it is determined whether or not pieces of the higher ranked related information thus preferentially searched agree with each other.Type: GrantFiled: November 20, 2013Date of Patent: May 26, 2015Assignee: KONICA MINOLTA, INC.Inventors: Kazutoshi Yoshimura, Katsunori Takahashi, Hiroyuki Watanabe, Kenichi Hayashi, Keigo Ogura, Takahiro Yokoya, Kenji Tamaki

Patent number: 9031429Abstract: A sheet of paper is set on a paper-supplying portion of a top surface gloss processing apparatus while its top surface is faced upward. A gloss level sensor measures gloss level of the top surface of the sheet of paper. Data of this measurement is compared with a previously set threshold value. Based on this comparison, it is determined whether or not the gloss processing has been performed on the top surface thereof. When determining that the gloss processing has been already performed, a warning message such that the gloss processing has been already performed on the top surface of the sheet, of paper is displayed on a screen. On the other hand, when determining that the gloss processing has not performed, the top surface gloss processing apparatus performs the gloss processing on the top surface thereof.Type: GrantFiled: February 7, 2013Date of Patent: May 12, 2015Assignee: Konica Minolta, Inc.Inventors: Teruo Shimao, Toshie Shimao, Katsunori Takahashi, Kenji Tamaki, Kenichi Hayashi, Yumiko Izumiya, Kazutoshi Yoshimura

Publication number: 20130206064Abstract: A sheet of paper is set on a paper-supplying portion of a back surface gloss processing apparatus while its top surface is faced upward. A gloss level sensor measures a gloss level of a back surface of the sheet of paper. Data of this measurement is compared with a previously set threshold value. When this measurement result does not exceed the threshold value, it is determined that the gloss processing has not been performed on the back surface thereof. It is then determined whether or not the presently set operation mode is a top surface gloss processing mode. When determining that the present operation mode is not the top surface gloss processing mode, the operation mode is automatically changed from a presently set back surface gloss processing mode to the top surface gloss processing mode.Type: ApplicationFiled: February 7, 2013Publication date: August 15, 2013Applicant: KONICA MINOLTA BUSINESS TECHNOLOGIES, INC.Inventors: Satoshi SHIMAO, Katsunori TAKAHASHI, Kenji TAMAKI, Kenichi HAYASHI, Yumiko IZUMIYA, Kazutoshi YOSHIMURA
