Patent number: 8139960Abstract: An image-forming device includes an electrophotographic image-forming section, a receptacle, a detecting unit, a shielding member, a drive mechanism. The electrophotographic image-forming section transfers developer onto a recording sheet to form developer image thereon. The receptacle collects developer not transferred onto the recording sheet. The receptacle includes a detection portion. The detecting unit detects light passing through the detection portion. The shielding member is movably disposed in the detection portion to move between a first position blocking the light to be detected by the detecting unit and a second position allowing the light to pass through the detection portion. The drive mechanism moves the shielding member between the first position and the second position in a direction different from a vertical direction.Type: GrantFiled: November 4, 2008Date of Patent: March 20, 2012Assignee: Brother Kogyo Kabushiki KaishaInventors: Yoshiyuki Okazaki, Takeshi Yamanaka

Patent number: 8023856Abstract: A belt is disposed in a main body and moves circularly to transport a recording medium placed thereon. A cleaning roller contacts an outer surface of the belt for removing extraneous matter deposited on the outer surface of the belt. A pair of backup rollers is disposed in opposition to the cleaning roller with the belt interposed between the backup rollers and the cleaning roller. The pair of backup rollers contacting the belt at first and second positions and the cleaning roller contacting the belt at a third position where the third position is interposed between the first and second positions. A holder rotatably holds the pair of backup rollers. Rotational axes of the backup rollers are kept parallel to each other. An urging unit urges the backup rollers toward the cleaning roller. A driving unit is supported on the main body and moves the holder to change a distance between the pair of backup rollers and the cleaning roller.Type: GrantFiled: October 22, 2008Date of Patent: September 20, 2011Assignee: Brother Kogyo Kabushiki KaishaInventor: Yoshiyuki Okazaki

Patent number: 7957834Abstract: Calculating a rotation center point on a plane of rotation of a positioning device by using a manipulator. The positioning device positions a workpiece by rotating the plane of rotation. The calculating includes a first step of obtaining location information of a predetermined position on the plane of rotation, a second step of rotating the plane of rotation of the positioning device 180 degrees, a third step of obtaining location information of the predetermined position on the 180-degree rotated plane of rotation, and a fourth step of calculating a point bisecting a straight line as the rotation center point of the plane of rotation of the positioning device from the location information obtained in the first step and the location information obtained in the third step, the straight line connecting the predetermined position of the first step and the predetermined position of the third step.Type: GrantFiled: January 17, 2007Date of Patent: June 7, 2011Assignee: Panasonic CorporationInventors: Yoshiyuki Okazaki, Masaya Hirayama
