Patent number: 11593574Abstract: In a printer, a controller controls a printing portion to execute a sample print to print on a sheet a plurality of barcodes. Each of the plurality of barcodes is represented by a received barcode data and printed in a different printing condition. The controller controls a reading portion to read the plurality of barcodes printed on the sheet in the sample print process to obtain a plurality of sets of scan data corresponding to respective ones of the plurality of barcodes. The controller performs a quality determination process to determine qualities of the plurality of printed barcodes based on the respective ones of the plurality of sets of scan data, and a printing condition setting process to set a printing condition based on the qualities determined in the quality determination process. The set printing condition is to be used to print a barcode by the printing portion.Type: GrantFiled: March 25, 2021Date of Patent: February 28, 2023Assignee: BROTHER KOGYO KABUSHIKI KAISHAInventors: Mitsuru Nakamura, Hideyuki Kusunoki, Yuji Sato, Keita Koyama, Katsunori Sakai, Akidi Yoshida, Ayaka Oba

Patent number: 9832336Abstract: In an image-reading device, a counting unit counts a number of clock cycles of a spread-spectrum clock as a counter value. A correcting unit corrects one of the counter value and a reference clock cycle number based on a phase detected by the phase detecting unit when the counting unit counts. A comparing unit compares the counter value and the reference clock cycle number and determines whether the counter value and the reference clock cycle number satisfy a prescribed relationship. A time length setting unit sets a length of at least one of a reading time and an irradiation time based on: a timing when the counting unit starts counting to set the time length; and a timing when the comparing unit determines that the compared values satisfy the prescribed relationship, such that the time length set by the time length setting unit remains constant.Type: GrantFiled: October 26, 2011Date of Patent: November 28, 2017Assignee: BROTHER KOGYO KABUSHIKI KAISHAInventor: Hideyuki Kusunoki

Patent number: 8614841Abstract: In an image-reader, the first counter is configured to count a first count value based on a first clock. The second counter is configured to count a second count value based on a second clock. The first reading unit is configured to read a first surface of a document sheet based on the first count value. The second reading unit is configured to read a second surface of the document sheet based on the second count value. The second surface is opposite surface of the first surface. When the first count value reaches a prescribed first value, both the first counter value and the second count value are reset.Type: GrantFiled: March 29, 2011Date of Patent: December 24, 2013Assignee: Brother Kogyo Kabushiki KaishaInventor: Hideyuki Kusunoki

Patent number: 8330989Abstract: A print control device includes a data acquiring section, a print control section, a preview-image output control section, and a print-ratio acquiring section. The data acquiring section acquires image data. The print control section controls a printing device to print an image based on the image data on a sheet. The preview-image output control section outputs preview images at a plurality of print ratios. The preview images are indicators of print results to be obtained when the printing device prints, on the sheet, the image based on the image data at the respective print ratios. The print-ratio acquiring section acquires print-ratio specifying information through an input device that can be operated by a user, after the preview-image output control section outputs the preview images. The print control section controls the printing device to print, on the sheet, the image based on the image data at a print ratio specified by the print-ratio specifying information.Type: GrantFiled: December 7, 2009Date of Patent: December 11, 2012Assignee: Brother Kogyo Kabushiki KaishaInventor: Hideyuki Kusunoki

Patent number: 8284228Abstract: An image forming apparatus includes an exposing unit and a first processing component. The first processing component is configured to generate a first data and a second data. The first data causes the exposing unit to blink in accordance with image data. The second data sets a blink mode of the exposing unit. The image forming apparatus also includes a second processing component connected to the first processing component through a first signal line. The second processing component is configured to receive the first data and the second data from the first processing component and perform blink control of the exposing unit based on the first data and the second data. The exposing unit is connected to the second processing component through a second signal line. The image forming apparatus thus can remedy a defect in data communication to the exposing units.Type: GrantFiled: February 11, 2009Date of Patent: October 9, 2012Assignee: Brother Kogyo Kabushiki KaishaInventor: Hideyuki Kusunoki
