Patent number: 8478175Abstract: A control portion obtains a first difference in a movement amount between paper passing period and paper non-passage period of a transfer belt, and determines whether or not a first absolute value thereof is a first threshold value or more. In a case where the first absolute value is the first threshold value or more, a transfer belt unit positional adjustment motor is driven to adjust a first angle with respect to a first direction of a transfer belt unit with respect to a photoreceptor drum. In a case where the first absolute value is less than the first threshold value, a second absolute value of a second difference between a movement amount and a designed value set in advance of the transfer belt is obtained, and whether or not the second absolute value is a second threshold value or more is determined.Type: GrantFiled: July 14, 2011Date of Patent: July 2, 2013Assignee: Sharp Kabushiki KaishaInventors: Hiroyuki Murai, Toshiki Takiguchi

Patent number: 8259086Abstract: A touch panel capable of calculating touch position coordinates of an indicator with high accuracy in a desired detection time even if a large number of detection wire groups are provided. An oscillator circuit selects one of detection wires and selected by a circuit or the like according to a command from a detection control circuit and oscillates. A circuit counts an output signal from the oscillator circuit up to a first count value. A circuit measures a period of the count. A circuit determines that there is a touch when it detects the detection wire of which the measured period is equal to or higher than a threshold value and sends the detection wire giving a maximum value equal to or higher than the threshold value to a circuit as a touch detection wire.Type: GrantFiled: November 10, 2008Date of Patent: September 4, 2012Assignee: Mitsubishi Electric CorporationInventors: Masafumi Agari, Naoki Nakagawa, Seiichiro Mori, Hiroyuki Murai

Patent number: 8121530Abstract: In an image forming method, an electrostatic latent image formed on a surface of a photoreceptor is developed into a developer image with a developer, and a printing paper transported on a transfer belt is brought into contact with the surface of the photoreceptor so as to transfer the developer image onto the printing paper. The printing paper is transported in a proper transport direction, in which a projection generated in one direction on the printing paper as a result of cutting the printing paper in a printing paper manufacturing process does not face a surface of the transfer belt at a leading edge of the printing paper being transported on the transfer belt. In this way, even in the presence of the projection generated when the printing paper is cut, the printing paper naturally strips off from the surface of the photoreceptor, thereby preventing toner contamination caused by a striping claw in contact with the leading edge of the printing paper.Type: GrantFiled: February 9, 2011Date of Patent: February 21, 2012Assignee: Sharp Kabushiki KaishaInventors: Toshiki Takiguchi, Hiroyuki Murai, Masato Kuze, Yuji Kumagai
