Abstract
A main frame (22) of a printer comprises a horizontal bottom plate (23e) and walls (23a to 23d) to form a box-shaped enclosure defining an inner space (23f). At least one of the walls is offset from the respective edge (104a to 104c) of the bottom plate to form an outer space (106) above the bottom plate (23e). A platen (8) and a carriage (10) are positioned in the inner space (23f) and fixed to the walls (23b, 23c) of the main frame (22). A controller board (3) and a power unit (4) are positioned in the outer space (106). An upper cover (13) has a top plate (13e) and walls (13a to 13d). The controller board (3) and the power unit (4) are positioned between the walls (13a to 13d) of the upper cover ( 13) and the walls (23a to 23d) of the main frame (23). The main frame (22) is formed by integral molding, and provides rigidity required for holding the platen (8) and the carriage (10), while collision or interference between the platen and the carriage (which move mechanically) and the controller board and the power unit is prevented.
