1. An image reading device comprising:
a board including a plurality of imaging elements arranged along a scanning direction and a plurality of board components arranged along the scanning direction, each of the plurality of board components being mounted with at least one imaging element included in the plurality of imaging elements; and
a housing including a plurality of optical components arranged along the scanning direction and a plurality of housing components arranged along the scanning direction, each of the plurality of optical components being configured to focus light reflected by a reading target onto a corresponding imaging element included in the plurality of imaging elements, each of the plurality of housing components holding at least one optical component included in the plurality of optical components, wherein
the plurality of housing components are arranged to have a first clearance therebetween,
the plurality of board components are arranged to have a second clearance therebetween,
each of the plurality of housing components and a corresponding board component included in the plurality of board components are fixed to each other at a position to transmit light through the optical component to focus onto the corresponding imaging element, and
the first clearance and the second clearance are arranged to be staggered in the scanning direction.
