Abstract:
1. An image recording apparatus, comprising: a platen which is adapted to support a recording sheet that is fed in a sheet-feed direction; a recording head which is movable along the platen, in a head-movement direction perpendicular to the sheet-feed direction, so as to record an image on the recording sheet; a frame assembly including a main frame which supports the platen, and at least one slide-base member which is supported by an upper portion of the main frame and which supports the recording head such that the recording head is slideable on said at least one slide-base member along the platen; at least one positioning device which positions said at least one slide-base member relative to the main frame in at least one horizontal direction and a downward direction, such that said at least one slide-base member is permitted to be displaced relative to the main frame in an upward direction; and at least one biasing device which includes at least one elastic member that produces an elastic force and is removable from the frame assembly, and which, in a state in which said at least one positioning device permits said at least one slide-base member to be displaced relative to the main frame in the upward direction, biases said at least one slide-base member toward the main frame by pressing, based on the elastic force produced by said at least one elastic member, an upper surface of said at least one slide-base member in at least the downward direction, wherein said at least one positioning device positions said at least one slide-base member relative to the main frame, such that in a state in which said at least one elastic member is removed from the frame assembly, said at least one slide-base member is permitted to be removed from the main frame in the upward direction.
