Abstract

Abstract In a printer which comprises a mechanical unit having a platen (8) a carriage (10) on which a print head (9) is mounted, and other mechanical components, a controller board (3) and a power unit (4) connected via connectors to the respective mechanical components (22b) of the mechanical unit, and an upper cover covering these from above, a main frame (22) comprising a mechanical component attachment section which has a horizontal bottom and walls erected from the bottom surface to form a box-like enclosure, and on which mechanically functioning components are attached, and a fastening section (22c) provided at the periphery of the mechanical component attachment section for fastening the controller board (3) and power unit (4), is formed by integral molding from a plastic material. Suitable plastic materials are ABS resin, PPO resin, PC/ABS polymer alloy resin, or ABS/PBT polymer alloy resin that is reinforced with glass fiber.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 115 words
A printer comprising: a mechanical unit having a platen, a carriage on which a print head is mounted, and other mechanical components; a controller board and a power unit connected via connectors to the respective mechanical components of the mechanical unit; and an upper cover covering these from above; wherein a main frame comprising a mechanical component attachment section which has a horizontal bottom and walls erected from the bottom surface to form a box-like enclosure, and on which mechanically functioning components are attached, and a fastening section provided at the periphery of the mechanical component attachment section for fastening the controller board and power unit, is formed by integral molding from a plastic material.
Claim 2
Dependent Claim 44 words
The printer of claim 1, wherein said main frame is formed, by injection molding, from ABS resin reinforced with glass fiber, PPO resin reinforced with glass fiber, PC/ABS polymer alloy resin reinforced with glass fiber, or ABS/PBT polymer alloy resin reinforced with glass fiber.
Claim 3
Dependent Claim 23 words
The printer of claim 1, wherein said mechanically functioning components include a platen, and a carriage on which a print head is mounted.
Claim 4
Dependent Claim 21 words
The printer of claim 1, wherein the mechanically functioning components are attached to the walls of said mechanical component attachment section.
Claim 5
Dependent Claim 49 words
The printer of claim 1, wherein said walls of the mechanical component attachment section comprises a front wall, a rear wall, and a pair of side walls, and said power unit is disposed adjacent said rear wall, and said controller board is disposed adjacent one of the side walls.
Claim 6
Dependent Claim 98 words
A printer comprising: a mechanical unit (21) including a platen, and a carriage on which a print head is mounted; a controller board (3) and a power unit (4) for driving the mechanical unit (6); and a cover (13) covering said board and units, characterised by a main frame (22) comprising a mechanical component attachment section (22b) for components of the mechanical unit, and a fastening section (22c) provided at the periphery of the mechanical component attachment section for receiving the controller board and power unit, the main fram being formed by integral molding of a plastics material.
