Publication number: 20100149576Abstract: The present invention provides a technique that can prevent an increase in power consumption due to intermittent execution of print jobs with low execution priorities and contribute to a reduction in CO2 emission. The technique is to discriminate content of a received print job, cause a storage medium to temporarily store, in a predetermined storage area, a print job discriminated as having first content with a low execution priority and cause an image forming apparatus to execute, together with the print job having the first content stored in the predetermined storage area, a print job discriminated by the job discriminating unit as having second content that should be more preferentially executed than the first content.Type: ApplicationFiled: December 15, 2009Publication date: June 17, 2010Applicants: KABUSHIKI KAISHA TOSHIBA, TOSHIBA TEC KABUSHIKI KAISHAInventor: Kazushige MORIHARA

Patent number: 7224931Abstract: The CPU of the image forming apparatus sets up an ADF reading magnification in the ADF driving unit including the motor and the motor driver referring to the first magnification conversion table in the memory of the system unit when reading a document image while a document is being moved. Further, the reading magnification that is also in the ADF driving unit is also set in the specific document detection unit. The specific document detection unit makes the pattern matching as to whether the read image data is that of a specific document using the magnification dictionary (specific image data) that is set and outputs a detection signal as the result of the matching to the CPU. As that time, the CPU controls the output of the applicable read image data by a printer according to the detection signal.Type: GrantFiled: December 10, 2004Date of Patent: May 29, 2007Assignees: Kabushiki Kaisha Toshiba, Toshiba Tec Kabushiki KaishaInventors: Naoaki Ide, Kazushige Morihara

Publication number: 20060275062Abstract: A fixing apparatus comprising a heating roller, a coil provided in the heating roller and configured to generate a high-frequency magnetic field, and capacitors and that constitute a resonant circuit, jointly with the coil. The resonant circuit is excited, sequentially (or alternately) at a plurality of frequencies which are nearly equal to the resonance frequency of the resonant circuit.Type: ApplicationFiled: August 14, 2006Publication date: December 7, 2006Inventor: Kazushige Morihara

Patent number: 7139495Abstract: If a temperature of a heat roller 12 rises abnormally, a thermostat 54 operates. When the thermostat 54 operates, a conduction path to an excitation coil 91 of a relay 90 is cut off so that a normally open contact 92 of the relay 90 can be operated. When the normally open contact 92 operates, the supply path of a drive signal supplied from a frequency variable oscillator 81 to a transistor 63 is cut off. By the cut-off, a high-frequency current does not flow through coils 14a to 14c; therefore, induction heating with respect to the heat roller 12 is stopped.Type: GrantFiled: December 23, 2003Date of Patent: November 21, 2006Assignees: Kabushiki Kaisha Toshiba, Toshiba Tec Kabushiki KaishaInventors: Kazushige Morihara, Hiroshi Nakayama
