Work device and image recording apparatus equipped with the work device

A work device, comprising:

• a movable member configured to reciprocate in a certain direction;
• a lengthy member which is connected to the movable member at a first-end-side portion near to a first end thereof, so as to extend in a first direction, and is elastically curved toward a second direction different from the first direction so that a second-end-side portion near to a second end thereof is fixed at a prescribed position, the lengthy member being operable to follow a reciprocating movement of the movable member;
• and
• a guide member having a first guide surface extending along the second direction, a second guide surface extending in a third direction that intersects the second direction, and a third guide surface contiguous to the first guide surface and the second guide surface,
• wherein the third guide surface is configured such that a boundary point in the lengthy member transits on the third guide surface from the first guide surface toward the second guide surface when the lengthy member contacting the first guide surface moves so as to come into contact with the second guide surface following the reciprocating movement of the movable member, the boundary point defining a boundary between a region of the lengthy member that is in contact with the third guide surface and a region of the lengthy member that is not in contact with the third guide surface.
