  • Publication number: 20220368030
    Abstract: A ground plane is disposed on or in an inner layer of a dielectric substrate. Moreover, a feed line is disposed on or in the dielectric substrate. A first antenna element and a second antenna element are supported on the dielectric substrate. The first antenna element and the second antenna element include a first radiating element and a second radiating element connected to the feed line, respectively, and are disposed on a same side when seen from the ground plane. With a height of the ground plane being a reference, a top portion of the second antenna element is located higher than a top portion of the first antenna element. There is provided an antenna device of which the band can be expanded and of which the internal space of the casing can be effectively utilized.

  • Patent number: 7050204
    Abstract: An optical reading apparatus and a multifunction-type image forming apparatus, with a minimized thickness in a cabinet height direction and a housing shaped along an upper shape of discharge tray of the image forming apparatus provided thereunder. The optical reading apparatus comprises: platen glass defined with one end and the other end, on an upper surface of which an original document is placed; an optical reading unit that translates between the both ends on a lower surface of the platen glass, for obtaining image data by irradiating an original document surface with light through the platen glass; a control circuit board connected to the optical reading unit, for processing an electric signal; and a housing wherein a side on the side of the other end is thicker than a side on the side of the one end.

  • Patent number: 6937367
    Abstract: The digital copier comprises a document table for supporting a document, a document tray for receiving documents, a line sensor for reading an image from each document in units of lines parallel to a main scanning direction, a sensor transporter for transporting the sensor to scan the document on the table from one reading surface edge in the sub-scanning direction during the table-document reading mode, a document feeder for feeding each document received in the tray such that the document is scanned from another reading surface edge in the sub-scanning direction during the feeder-document reading mode, and a processing section for processing a reading result of the sensor. Particularly, the processing section has a controller for controlling the read start timing to compensate for a read range which may deviate with respect to an identical effective reading area of each document between the reading modes.

  • Patent number: 6501919
    Abstract: When an instruction to start copying is provided, a CPU estimates heat time required until the temperature of a heater of a printer reaches an operating temperature. The CPU also estimates read time required for reading an original document by a scanner. Then, the CPU subtracts the read time from the heat time to obtain standby time and causes the scanner to start reading the original document when the standby time elapses from when the instruction to start copying is provided.
