摘要： An inkjet printer that automatically expels bubbles trapped at a filter―which removes foreign materials from ink supplied to the inkjet head―to eliminate ink discharge problems caused by trapped air bubbles. Ink (40) is supplied through ink-supply-line part (23), filter (24), and ink-intake opening (202) to inkjet head (2) of inkjet printer (1). If a bubble (30) in ink (40) becomes trapped at the top surface (24a) of filter (24), the bubble (30) is separated from the filter top (24a) by the buoyancy of the ink (40). When the bubble (30) separates from the filter top (24a), it forms a spherical bubble (30A). This spherical bubble (30A) then rises through conically shaped ink-path-connection part 222 and ink-supply-line part 23. The internal volume of ink-path-connection part 222 is less than 1.1 times the volume of a sphere internally tangent to ink-supply-line part 23. Therefore, bubble (30A) freely rises through ink-supply-line part 23. Print defects that occur when a bubble (30) is trapped at the filter top are, therefore, prevented.

摘要： In a print wheel selection type compact printer print wheels (3) are mounted on a print wheel shaft (1) to be rotated into specific angular positions for type selection. A print wheel spring (2) is arranged between each print wheel (3) and the print wheel shaft (1) and forms part of a clutch mechanism to either couple the respective print wheel (3) to or release it from the print wheel shaft (1). One or more indentations (1a, 1e) are provided in the print wheel shaft (1) for each print wheel (3) and adapted to be engaged by or disengaged from a protrusion (2a) of the print wheel spring (2). The leading surface in the direction of rotation of said print wheel shaft (1) of the profile of one or both of the indentation (1a) of the print wheel shaft (1) and the protrusion (2a) of the print wheel spring (2) comprises at least two surfaces of different slants.
