1. An image reading device comprising:
a board including a plurality of imaging elements arranged along a scanning direction; and
a housing including a plurality of optical components arranged along the scanning direction and a plurality of housing components arranged al mg 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 top surface thereof on a same plane and to have a first clearance therebetween,
the first clearance has a crank shape when viewed from a direction through which light enters each of the plurality of optical components,
each of the plurality of housing components is fixed to the board at a position to transmit light through the optical component to focus onto the corresponding imaging element, and
each of the plurality of housing components has a surface facing the board and is fixed to the board at a region including a center of the surface.
