  • Patent number: 10347068
    Abstract: A capacitance detection device includes a first electrode and a second electrode that at least partially face each other on opposite sides of a transfer path. An oscillator circuit forms an electric field between the first electrode and the second electrode. A detection circuit detects a change in capacitance between the first electrode and the second electrode. At least one of the oscillator circuit and the detection circuit is included in each of a first board and a second board. The first board is disposed such that a side surface of the first board faces the first electrode in an electric field direction, and the second board is disposed such that a side surface of the second board faces the second electrode in the electric field direction.

  • Patent number: 9407217
    Abstract: When a switch is set to off, and a switch is set to on, the voltage of a SigOut terminal is stabilized with a reference voltage, and a bias voltage is applied to a capacitor. Changing the switch from on to off, with the bias voltage retained in the capacitor, a detection signal which is input via a SigIn terminal is amplified with the reference voltage as a reference, and an amplified signal is output from the SigOut terminal.

  • Patent number: 9396366
    Abstract: A magnetic sensor device includes magnetic detection elements arrayed along a line intersecting the relative movement direction of a medium, and a magnet applying a bias magnetic field to the magnetic detection elements with a line of magnetic force in the constant direction. The magnetic sensor device detects a magnetic field change when a medium with a magnetic pattern passes through the bias magnetic field as an electric signal through the magnetic detection elements and reads the magnetic pattern of the medium. A plurality of reading switches is connected to the respective magnetic detection elements and an output line common to the magnetic detection elements. The magnetic sensor device includes a shift register closing the reading switches sequentially one by one to transfer the outputs from the magnetic detection elements sequentially one by one to the output line.

  • Patent number: 9244135
    Abstract: A magnetic sensor device includes a first magnet and a second magnet that are disposed on mutually opposing sides of a conveyance path, and one of poles of the first magnet faces an opposite pole of the second magnet. The first magnet and the second magnet generate a cross magnetic field whose strength in a spacing direction, which is orthogonal to a conveying direction, is within a predetermined range. An AMR element is located in a magnetic field in which the strength of the cross magnetic field in the spacing direction is within a predetermined range, and detects, as change in a resistance value, change in the cross magnetic field caused by an object to be detected. A multilayer board outputs the change in the resistance value detected by the AMR element to a processing circuit.

  • Patent number: 7995252
    Abstract: An image reading apparatus includes an illuminating optical system having light sources arranged in a line and a light guide member guiding rays of light from the light sources to illuminate a document which passes through a document reading position near a light emergent surface of the light guide member. An image reading optical system includes a rod lens array to read light passing through the document, and a cylindrical lens array in the light emergent surface of the light guide member. Ridge lines running along a subscanning direction on the light guide member are aligned in a scanning direction.
