A lens array unit includes a lens array including a plurality of lenses, a first side plate, and a second side plate, the first side plate and the second side plate being configured to hold the plurality of lenses therebetween, and a frame made of resin and including a first supporting portion and a second supporting portion, the first supporting portion being in contact with an outside surface of the first side plate, the second supporting portion being in contact with an outside surface of the second side plate, the first supporting portion and the second supporting portion being configured to hold the lens array therebetween and support the lens array. The outside surface of the first side plate includes a plurality of first concave portions spaced from each other in an array direction of the lenses and configured to fit with the first supporting portion.

A scan assembly comprises a monolithic metal frame having an outer wall defining an interior frame portion. The interior frame portion has a scan region to support and at least partially house a scan unit to be movable within and relative to the scan region and has a control region to support and at least partially house a control panel. The outer wall has a first face exposed to the interior frame portion and an opposite second face to be directly exposed to an external environment.

Vision systems including a swappable camera and methods of making and using the swappable camera are disclosed. The swappable camera can include an alignment indicator storing alignment data representative of an array-housing alignment of a sensor array relative to a camera housing. The swappable camera can have a desired sensor array position. A region of interest that is concentric with the desired sensor array position can be determined using the alignment data and an image can be acquired using only pixels of the sensor array that are located within the region of interest.

The invention relates to an image reading apparatus and includes: scanning unit including a light source; a focusing mirror which reflects light from the light source on a reflecting surface portion; and a mirror holder which fixes the focusing mirror on fixing portions formed at both ends of the mirror holder, wherein, when the scanning unit is moved to read image information, the focusing mirror is formed such that the fixing portion is smaller than the reflecting surface portion in at least one of strength and rigidity.
