Provided is a device housing made of materials containing at least an electrically conductive material, an image reading device, and an electrostatic capacitance detection device that can achieve electrical connection with a relatively small space while preventing deformation of the device housing. The device housing includes a housing made of materials containing at least an electrically conductive material and including an electrically conductive surface in at least part of the surface of the housing, a ground conductor being present on a plane different from the plane including the electrically conductive surface, and a ground auxiliary conductor disposed over a level difference existing between the plane including the electrically conductive surface and the plane including the ground conductor. The ground auxiliary conductor is an electrically conductive sheet to connect the electrically conductive surface to the ground conductor electrically.

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.

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.

Capacitive sensor

An image sensor unit includes: a visible light cut filter that is arranged between a first light source and a first light guide and blocks light including visible light having wavelengths longer than those of ultraviolet light; a lens body that condenses light generated on a reading target by light radiated from the first light guide and light radiated from a second light guide; a line sensor that receives the light condensed by the lens body; and an ultraviolet light cut filter arranged between the lens body and the line sensor and blocks ultraviolet light.

In one embodiment, a charged particle beam writing method is for writing a pattern in a writing area on a substrate by irradiating a charged particle beam onto the substrate while moving the substrate to write stripes sequentially, each of the stripes having a width W and shapes obtained by dividing the writing area by the width W. The method includes performing S times (S is an integer greater than or equal to two) strokes, each of the strokes which is a process writing the stripes in a multiplicity of 2n (n is an integer greater than or equal to one) while shifting a reference point of each of the stripes in the width direction by a preset stripe shift amount and changing a moving direction of the substrate for each of the stripes, and writing while the reference point of the stripes in the each of the strokes in the width direction of the stripes is shifted by a preset stroke shift amount in each of the strokes.

A lighting device includes a rod-shaped light guide, a light guide holder, and an opening optically communicating with the hole. The opening is formed in a first flat surface opposite to a surface into which an end surface of the light guide is inserted. The device also includes a housing, a light source base plate, and a base plate protection layer being formed on a region of the light source base plate other than at least a region on which a light source element is formed. At least one of the light source base plate and the second flat surface of the base plate protection layer is pressed against the housing or the first flat surface at a position at which light emitted by the light source element enters the end surface of the light guide exposed from the opening.

Sheet identification sensor

A magnetic sensor device includes a magnet to form a magnetic field in a conveyance path of a detection target, a magnetoresistance effect element to output a change in the magnetic field as a change in a resistance value, a casing to enclose or hold the magnet and the magnetoresistance effect element, a cover to cover the magnetoresistance effect element and form a conveyance path surface that is a surface along the conveyance path, and a signal amplification board having a signal amplification IC disposed on an intersection surface that intersects the conveyance path surface. The signal amplification IC amplifies the change in the resistance value that is output by the magnetoresistance effect element. The change in the resistance value depends on the change in the magnetic field caused due to conveyance of the detection target on the conveyance path surface.

The opening () 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 () are nearer to the sensing target in Z-axis direction than the two short sides.
