    摘要: An illumination device and an image reading device are characterized by including: a rod-shaped light guide extending in a longitudinal direction and configured to guide light entering from an exterior and emit the light as linear light from a lateral surface; a light guide holding portion having a hole into which an end surface of the light guide is inserted; a supporter supporting the light guide holding portion slidably along the longitudinal direction; and a housing supporting or housing the light guide, the light guide holding portion and the supporter, at least the supporter being fixed to the housing, a direction of sliding of the light guide holding portion being restricted to the longitudinal direction by a supporter-side concave-convex portion that is a supporter-side groove portion or a supporter-side protruding portion at least one of which is formed on the supporter along the longitudinal direction.

    摘要: A magnetic sensor device includes: a magnet; a magnetic-resistance-effect-element mounted substrate on which a magnetic-resistance-effect-element mounted body is mounted on a surface thereof opposite to a surface thereof facing the magnet, the magnetic-resistance-effect-element mounted body extending in the longitudinal direction of the magnet; a case that accommodates or retains the magnet and the magnetic-resistance-effect-element mounted substrate; and a magnetic shield that covers the case except for the surface of the magnetic-resistance-effect-element mounted substrate on which is mounted the magnetic-resistance-effect-element mounted body. The magnetic shield covers the case at a position corresponding to the surface of the magnetic-resistance-effect-element mounted substrate facing the magnet, or from the position corresponding to the surface of the magnetic-resistance-effect-element mounted substrate facing the magnet to a side of the case opposite to the magnet.

    摘要: A magnetic field generator disposed on one surface side of a sheet-shaped object-to-be-detected contains a magnetic component. The magnetic field generator includes a first magnetic pole part that forms a first magnetic pole, and a second magnetic pole part that forms a second magnetic pole with reverse polarity of the first magnetic pole. The magnetic field generator generates a cross magnetic field that crosses the object-to-be-detected. An MR element is disposed between the first magnetic pole part and the object-to-be-detected. The resistance value of the MR element changes according to a change in a component of the cross magnetic field in a conveying direction. The position of the MR element in the conveying direction is position shifted along the conveying direction from the center position of the first magnetic pole part in the conveying direction, and located between both ends of the first magnetic pole part in the conveying direction.

    摘要: Light guides emit light from the side surface thereof toward the subject to be read, the light emitted to one end surface of each of the light guides. A frame is frame shaped, the frame houses the light guides and a lens, the frame including light guide holders that support a first to-be-supported section on the side surface of the light guides. A cover covers at least a part of one opening of the frame, and does not restrict light from passing through between the light guides and the subject to be read, the cover including light guide holders that support a second to-be-supported section opposite of the first to-be-supported section on the side surface of the light guides. The light guides are fixed inside the frame by the flange portion including the light guide holders provided by the frame and the light guide holders provided by the cover.
