摘要： An image reading device includes a board including a plurality of imaging elements arranged along a scanning direction, and a housing including a plurality of optical components that are arranged along the scanning direction and a plurality of housing components that are arranged along the scanning direction. Each of the plurality of optical components focuses light reflected by a reading target onto a corresponding imaging element, and each of the plurality of housing components holds at least one optical component. The plurality of housing components are arranged to have a clearance therebetween and each of the plurality of housing components is fixed to the board at a position to transmit light through the optical components to focus onto the corresponding imaging element.

摘要： 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.

摘要： An image reading device (1) includes a board (24) including a plurality of imaging elements (23) arranged along a scanning direction, and a housing (13) including (i) a plurality of optical components that are arranged along the scanning direction and (ii) a plurality of housing components (13a, 13b) that are arranged along the scanning direction. Each of the plurality of optical components focuses light reflected by a reading target onto a corresponding imaging element (23), and each of the plurality of housing components holds at least one optical component. The plurality of housing components (13a, 13b) are arranged to have a clearance therebetween and each of the plurality of housing components (13a, 13b) is fixed to the board (24) at a position to transmit light through the optical components to focus onto the corresponding imaging element (23).

摘要： The present disclosure relates to an image reading device having a highly-accurate structure that enables an easy increase in depth of field, that is, improvement in the depth of the field, without need for a change in basic characteristics of lenses. An overlap preventer (5) disposed between a lens array (1) and a sensor element array (3) to prevent overlap of images formed by lenses (2) is included. A slit section (5) that is the overlap preventer (5) includes multiple slit plates (7) arranged in a main scanning direction and extending in a sub-scanning direction to partition off a space, and the slit plates (7) are fixed to fixing plates (13).
