Claims
- 1. A recording apparatus for recording data on a recording medium, said apparatus comprising:
- a conveyance passage through which a recording medium passes;
- recording means capable of moving along said conveyance passage through which the recording medium passes and recording data on the recording medium;
- conveyance means for conveying the recording medium through said conveyance passage;
- moving means for moving said recording means along said conveyance passage;
- a driving source for generating driving power;
- first transmission means for transmitting the power from said driving source to said conveyance means;
- second transmission means for transmitting the power from said driving source to said moving means;
- shifting means for selectively connecting and disconnecting said first transmission means and said driving source while maintaining a connection between said driving source and said second transmission means; and
- control means for controlling both a medium conveyance process in which the recording medium is conveyed by transmitting the power from said driving source to said medium conveyance means via said shifting means and a recording means movement process in which said shifting means does not transmit the power to said medium conveyance means and said driving source is operated so as to correct the amount of the movement of said recording means which has been moved as a result of the medium conveyance process.
- 2. A recording apparatus according to claim 1, wherein said shifting means comprises a serration gear, a clutch gear and a solenoid.
- 3. A recording apparatus according to claim 1, wherein said second transmission means also serves as a portion of said first transmission means.
- 4. A recording apparatus according to claim 1, wherein said first transmission means comprises a bevel gear and an intermediate gear.
- 5. A recording apparatus according to claim 1, wherein said second transmission means comprises a bevel gear.
- 6. A recording apparatus according to claim 1, wherein said recording means comprises a daisy wheel.
- 7. A recording apparatus according to claim 1, wherein said recording means includes a discharge port and uses ink in an ink jet recording method in which thermal energy is utilized so as to discharge the ink through said discharge port to record.
- 8. A recording apparatus according to claim 1, wherein said recording means includes discharge ports and electrothermal converters and discharges ink through said discharge ports by growth of bubbles due to film boiling caused by heat energy generated by said electrothermal converters.
- 9. A recording apparatus for recording data on a recording sheet, said recording apparatus comprising:
- a conveyance passage through which a recording sheet passes;
- a carriage capable of moving along said conveyance passage through which the recording sheet passes;
- recording means mounted on said carriage for recording data on the recording sheet;
- a driving source for generating driving force;
- sheet conveyance means for conveying the recording sheet;
- carriage moving means for moving said carriage by the force supplied from said driving source;
- power transmission means for transmitting force from said driving source to said sheet conveyance means;
- shifting means for selectively transmitting the force to said sheet conveyance means via said power transmitting means; and
- control means for controlling both a sheet conveyance process in which the recording sheet is conveyed by transmitting the force from said driving source to said sheet conveyance means via said shifting means and a carriage movement process in which said shifting means does not transmit the force to the sheet conveyance means and said driving source is operated so as to correct the amount of the movement of said carriage which has been moved as a result of the sheet conveyance process.
- 10. A recording apparatus for recording data on a recording sheet, said recording apparatus comprising:
- a conveyance passage through which a recording sheet passes;
- a carriage capable of moving along said conveyance passage through which the recording sheet passes, said carriage movable between a stop position and recording positions;
- recording means mounted on said carriage for recording data on the recording sheet;
- a driving source for supplying a driving force;
- sheet conveyance means for conveying the recording sheet;
- carriage moving means for moving said carriage by the force supplied from said driving source in increments of at least a minimum printing resolution;
- power transmission means for transmitting the force from said driving source to said sheet conveyance means;
- shifting means for selectively transmitting the force to said sheet conveyance means via said power transmission means; and
- control means for controlling both a sheet conveyance process in which the recording sheet is conveyed by transmitting the force from said driving source to said carriage moving means and said sheet conveyance means via said shifting means and a carriage movement process in which said shifting means does not transmit the force to the sheet conveyance means and said carriage is moved, wherein said driving source is operated in the carriage movement process such that said carriage moving means moves said carriage to a desired recording position, even if the distance between a position to which said carriage is moved in said sheet conveyance process and the desired recording position is less than the minimum printing resolution of said carriage moving means.
- 11. A recording apparatus for recording data on a recording sheet, said recording apparatus comprising:
- a conveyance passage through which a recording sheet passes;
- a carriage capable of moving along said conveyance passage through which the recording sheet passes;
- recording means mounted on said carriage for recording data on the recording sheet;
- a driving source for supplying a driving force;
- sheet conveyance means for conveying the recording sheet;
- carriage moving means for moving said carriage in increments of at least a minimum printing resolution by the force supplied from said driving source;
- power transmission means for transmitting the force from said driving source to said sheet conveyance means;
- shifting means for selectively transmitting the force to said sheet conveyance means via said power transmitting means; and
- control means for controlling each of a sheet conveyance process is which the recording sheet is conveyed by transmitting the force from said driving source to said carriage moving means and said sheet conveyance means via said shifting means, and a correction process in which said shifting means does not transmit the force to the sheet conveyance means, wherein said driving source is operated in the correction process to a degree to compensate for the distance said carriage moves in said sheet conveyance process, even if the distance between a position of said carriage at the end of said sheet conveyance process and a desired recording position is less than the minimum printing resolution of said carriage moving means, and a carriage movement process in which said driving source is, after said correction process, operated to a degree to move said carriage to the desired recording position.
- 12. A recording apparatus according to any one of claims 9, 10 and 11, wherein said recording means comprises a daisy wheel.
- 13. A recording apparatus according to any one of claims 9, 10 and 11, wherein said recording means includes a discharge port and uses an ink jet recording method in which thermal energy is utilized so as to discharge ink through said discharge port to record.
- 14. A recording apparatus according to any one of claims 9, 10 and 11, wherein said recording means includes electrothermal converters and discharge ports and discharges ink through said discharge ports by growth of bubbles due to film boiling caused by heat energy generated by said electrothermal converters.
- 15. A recording apparatus according to any one of claims 9, 10 and 11, further comprising an individual table and a common table, wherein said carriage movement process is performed by said control means selecting data from the individual table and the common table.
- 16. A recording apparatus according to any one of claims 9, 10 and 11, wherein said control means comprises an individual data table exclusively used for removing backlash.
