Abstract: An image reading device (100) includes a lens array (4), a light receiver (6), and at least one light blocking member. The lens array (4) includes first lens bodies arranged in a line in a main scanning direction with predetermined spacing therebetween to converge light from a reading target. The light receiver (6) receives light converged by each first lens body. The at least one light blocking member is disposed between the light receiver (6) and an end of the lens array (4) proximate to the reading target at at least one position corresponding to the predetermined spacing in the main scanning direction. The at least one light blocking member blocks light from the reading target propagating between the first lens bodies, and each of the at least one light blocking member separates optical paths of light converged by ones of the first lens bodies adjacent to each other.

Abstract: A magnetic sensor device includes: a magnetic circuit for forming a magnetic field, a magnetoresistance effect element, and a heat dissipater. The magnetoresistance effect element outputs changes in the magnetic field as changes in a resistance value, and is arranged on a surface (of a +Z side) of the magnetic circuit at a conveyance path side thereof. The heat dissipater is arranged in close contact with the magnetic circuit at the opposite side thereof (−Z side) from the conveyance path.

Abstract: 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.

Abstract: 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.

Abstract: An optical member includes a lens array including lens bodies, and transmissive members. The transmissive members are made of a material having a uniform refractive index, and are disposed at positions nearer an object-to-be-read than the corresponding lens bodies are disposed or at positions farther from the object-to-be-read than the corresponding lens bodies are disposed. The transmissive members have a columnar shape extending along the optical axes of the lens bodies, and allow light incident through one end faces to exit through the other end faces. At least either ones of the lens bodies or the transmissive members are arranged with distances therebetween larger than errors in the arrangement of the lens bodies and the transmissive members.

Abstract: A magnetic sensor device (10) includes a magnetic sensor unit including a magnetoresistive element mounted on a sensor board extending in a longitudinal direction and a magnet (3) located on a surface of the sensor board opposite to a surface on which the magnetoresistive element is mounted, a housing supporting the magnetic sensor unit, a magnetic shield unit (4) covering side surfaces and a bottom surface of the housing, and a cover covering an upper portion of the housing. The magnetic shield unit (4) has an opening (4o) facing in Z-axis direction from the magnetoresistive element toward a transport path of a sensing target. The opening (4o) is defined by two long sides in the longitudinal direction and two short sides in a lateral direction. The two long sides of the magnetic shield unit (4) are nearer to the sensing target in Z-axis direction than the two short sides.

Abstract: An optical member includes a lens array including lens bodies, and transmissive members. The transmissive members are made of a material having a uniform refractive index, and are disposed at positions nearer an object to be read or at positions farther from the object to be read than the corresponding lens bodies are disposed. The transmissive members have a columnar shape extending along the optical axes of the lens bodies, and allow light incident through one end faces to exit through the other end faces. The optical axes of the lens bodies are deviated from the central axes of the transmissive members corresponding to the respective lens bodies at least in the sub-scanning direction, and an end face of the transmissive member to which an end face of each lens body is opposed is thereby an end face of the corresponding transmissive member.
