摘要:
A shuttle apparatus for a printer having a print shuttle unit driven to reciprocate. The print shuttle unit includes a print shuttle provided with a print head and movable along a guide device. A row of permanent magnets are attached to the print shuttle, and a row of electromagnetic coils are secured to a stationary member so as to face the permanent magnets across a gap. The coils and the permanent magnets constitute a linear motor for reciprocating the print shuttle unit along the guide device. A balance shuttle unit having approximately the same weight as that of the print shuttle unit is disposed so that the center of gravity of the balance shuttle unit travels on a line approximately the same as the line of travel of the center of gravity of the print shuttle unit. The balance shuttle unit is driven to reciprocate in linked relation to the print shuttle unit in parallel but reverse in direction to the print shuttle unit.

An information processing apparatus creates drawing data using print setting information and print data. The information processing apparatus includes: a converting module that converts the print setting information to apparatus setting information handled in the information processing apparatus; a control mode determining module that analyzes the print setting information to thereby determine a control mode applicable when the drawing data is created; a drawing data creating module that creates drawing data using the apparatus setting information and the print data; and a creating module control module that controls the drawing data creating module according to the control mode.

Disclosed is a shuttle mechanism of a dot line printer including a printing shuttle unit making a reciprocating motion to perform dot printing and a balance shuttle unit making a motion in a direction opposite to the kinetic motion of the printing shuttle unit. This shuttle mechanism is constructed of a linear motor in which a movable unit for the reciprocating motion and a magnetic circuit are separated. With this construction, the movable unit can be decreased in weight. Therefore, the high-speed reciprocating motion can be made, and high-speed printing is thereby attainable. The balance shuttle unit is disposed under the printing shuttle unit. The apparatus can be thereby made compact.

A pair of feed rollers for sending an ink ribbon into a ribbon case have a number of grooves on the circumferential faces thereof such that opposed grooves do not mesh with each other. A heater is disposed in a travel path for the ink ribbon, for heating the ink ribbon to prevent deterioration of the drawability of the ink ribbon drawn by the pair of feed rollers.
