| 1. An image recording apparatus comprising:
a linear encoder which includes a linear scale having a plurality of detectable portions angled at a predetermined pitch and
a detector which detects the plurality of detectable portions while being moved along the linear scale; and
a linear scale support device having a pair of support sections which support opposite ends of the linear scale, respectively,
so as to set up the linear scale in a tensioned state in a main scanning direction,
one of the pair of support sections including (a) a support member which is substantially rigid, which has a holding portion
that holds one of the opposite ends of the linear scale and which is movable such that the holding portion moves along a predetermined
path, and (b) an elastic member which biases the support member in a direction in which the holding portion moves away from
the other of the opposite ends of the linear scale.
