Publication number: 20220116512Abstract: An electronic document managing apparatus for managing an electronic document includes a hardware processor. The hardware processor obtains the electronic document and manages an approval state of the obtained electronic document. In response to receiving an instruction to output the electronic document, the hardware processor refers to the approval state. The hardware processor permits the output of an approved electronic document only when all of a predesignated approver has approved the electronic document, the approved electronic document being the electronic document bearing a seal image of all of the approver. The hardware processor does not permit the output of the electronic document bearing any of the seal image when any of the approver has not approved the electronic document yet.Type: ApplicationFiled: September 13, 2021Publication date: April 14, 2022Applicant: KONICA MINOLTA, INC.Inventor: Kosuke MASUMOTO

Patent number: 10740879Abstract: There are provided an image reader, a noise canceller, and an image processor. The image reader reads an image, outputs image data, and generates a horizontal synchronization signal. The noise canceller generates a noise-canceling signal to eliminate a noise entering a horizontal synchronization signal and eliminates a noise from a horizontal synchronization signal. The image processor captures effective image data out of image data transferred from the image reader correspondingly to a timing when the horizontal synchronization signal changes from a first signal level to a second signal level. The noise canceller generates a noise-canceling signal from a noise detection signal or image data generated in the image reader.Type: GrantFiled: January 10, 2019Date of Patent: August 11, 2020Assignee: KONICA MINOLTA, INC.Inventor: Kosuke Masumoto

Patent number: 10564904Abstract: An image forming apparatus causes an image forming portion to perform image forming processing based on a security job issued by an output-permitted user, in a case where an outsider-use-possibility calculated by an outsider-use-possibility calculation portion becomes equal to or smaller than a predetermined threshold value on the basis of information of a movement trajectory of the output-permitted user and also the output-permitted user has been detected in an output-process-start area. Accordingly, it is possible to enhance the convenience for the output-permitted user while ensuring the security of the output product based on the security job issued by the user.Type: GrantFiled: May 17, 2017Date of Patent: February 18, 2020Assignee: Konica Minolta, Inc.Inventor: Kosuke Masumoto

Patent number: 9986122Abstract: When other user is using an image forming apparatus before an output-permitted user having issued a security job reaches the image forming apparatus, security is lowered and also it takes some time until processing of security job is completed. The image forming apparatus notifies the output-permitted user of information indicating that other user is using the image forming apparatus in a case where the other user present near the image forming apparatus (own apparatus) is using the image forming apparatus. With this arrangement, the output-permitted user can know whether or not the other user is using the image forming apparatus before the output-permitted user reaches the image forming apparatus.Type: GrantFiled: November 18, 2016Date of Patent: May 29, 2018Assignee: KONICA MINOLTA, INC.Inventor: Kosuke Masumoto

Patent number: 9898211Abstract: A nonvolatile memory control device performs data reading/writing control on partitions of a rewritable nonvolatile semiconductor memory. The device includes an erase cycle counting unit, a read cycle counting unit, a data reading/writing unit and a control unit. The erase cycle counting unit counts the number of erase cycles in total per partition. The read cycle counting unit counts the number of read cycles that same data is read per partition. When the number of erase cycles of a first partition is equal to or larger than a predetermined number of erase cycles, and a second partition having a smaller number of erase cycles and a larger number of read cycles than the first partition is present, the control unit controls the data reading/writing unit to exchange data in the first partition and data in the second partition.Type: GrantFiled: December 11, 2015Date of Patent: February 20, 2018Assignee: KONICA MINOLTA, INC.Inventors: Kosuke Masumoto, Takashi Hasebe
