20110080571 | RECORDING MEDIUM IMAGING APPARATUS - A recording medium imaging apparatus includes an irradiation unit configured to irradiate a recording medium with light, an imaging unit configured to capture reflected light which is irradiated by the irradiation unit and reflected by the recording medium as a surface image, and a reference plate which includes a background that reflects light irradiated by the irradiation unit, and a mark that has a different reflectance ratio to the background, wherein the imaging unit captures reflected light reflected by the reference plate as a surface image and includes a control unit that determines a type of the recording medium based on the surface image of the reference plate and the surface image of the recording medium. | 04-07-2011 |
20110142459 | RECORDING MEDIUM DETERMINATION APPARATUS AND IMAGE FORMING APPARATUS - The timing of obtaining an output value for use in a determination of a recording medium is generated from a received ultrasonic wave and a waveform generated by delaying the ultrasonic wave, whereby it is possible to reduce an influence of a reflection wave from the peripheral members and an influence of a change in the environment to improve the accuracy of determination of the recoding medium. | 06-16-2011 |
20130236206 | POWER SUPPLY DEVICE AND IMAGE FORMING APPARATUS - The power supply device includes a transformer, a switching unit for driving a primary side of the transformer, a detection unit for detecting an output corresponding to a current flowing on the primary side, a transmission unit for transmitting an output voltage from a secondary side to the primary side, and a control unit for controlling an operation of the switching unit in accordance with an output from the transmission unit, in which, when a switching frequency for driving the switching unit falls within a predetermined frequency range including a resonant frequency of the transformer, the control unit controls the switching unit so as to shorten a turn-ON time of the switching unit in accordance with an output from the detection unit. | 09-12-2013 |
20130293907 | IMAGE FORMING APPARATUS - The image forming apparatus includes an image forming unit for forming an image on a recording material; an original read unit for reading an original at a read position facing a conveyance path in which the recording material and the original are to be conveyed selectively, and a control unit for switching a position of the original read unit to a position different from the read position during a period in which the recording material is being conveyed along the conveyance path. | 11-07-2013 |
20130293909 | IMAGE FORMING APPARATUS - The image forming apparatus includes a conveyance path that is used to convey a recording material to form an image on the recording material, a reading unit that reads an original conveyed in the conveyance path, and a control unit that controls a recording material conveyance operation to selectively convey the recording material and the original to the conveyance path. | 11-07-2013 |
20130293937 | READING APPARATUS - A reading apparatus including:
| 11-07-2013 |
20140079456 | IMAGE FORMING APPARATUS FOR PERFORMING A DOCUMENT READING OPERATION AND A PRINTING OPERATION IN PARALLEL - When images of a plurality of document sheets are to be read and formed on a plurality of recording materials, an image forming apparatus performs control to convey a document sheet and a recording material at one of a recording material conveyance speed and a document conveyance speed, whichever is lower. | 03-20-2014 |
20140079457 | IMAGE FORMING APPARATUS WITH AUTOMATIC DOCUMENT FEEDER - An image forming apparatus performs control to parallelly achieve document image reading by a reading unit and image formation by an image forming unit for forming on a recording material a document image read by the reading unit. | 03-20-2014 |
20140105625 | RECORDING MEDIUM DETERMINATION APPARATUS AND IMAGE FORMING APPARATUS - The timing of obtaining an output value for use in a determination of a recording medium is generated from a received ultrasonic wave and a waveform generated by delaying the ultrasonic wave, whereby it is possible to reduce an influence of a reflection wave from the peripheral members and an influence of a change in the environment to improve the accuracy of determination of the recoding medium. | 04-17-2014 |
20140320877 | IMAGE FORMING APPARATUS - An image forming apparatus includes a first conveying path guiding a sheet such that the sheet passes through the image forming portion, a second conveying path guiding the sheet on which the image is formed by the image forming portion to the first conveying path. A document is fed to the second conveying path and the image forming apparatus includes a first drive transmission portion transmitting a drive force to the image forming portion and a second drive transmission portion transmitting the drive force to a document feeding portion, a conveyance portion and a document discharge portion. | 10-30-2014 |
20140320940 | IMAGE FORMING APPARATUS - An image forming apparatus includes a sheet feed portion configured to feed a sheet, an image forming portion configured to form an image on the sheet, a first conveying path configured to guide the sheet fed from the sheet feed portion such that the sheet passes through the image forming portion, a second conveying path configured to guide the sheet on which the image has been formed on one surface thereof by the image forming portion to the first conveying path again, a document feed portion configured to feed a document to the second conveying path, an image reading portion configured to read an image of the document fed by the document feed portion, and a control portion configured to control the sheet feed portion and the document feed portion such that the document and the sheet are conveyed on the second conveying path in a sequence in which the document and the sheet are mixed in a case where an operation of forming images respectively on both surfaces of a plurality of sheets overlaps with an operation of reading images of a plurality of documents. | 10-30-2014 |
