Abstract
A data processing device for writing various kinds of rule data easily and rapidly in a pixel image memory. Rule pattern store means stores a plurality of kinds of rule patterns in the line direction and a plurality of kinds of rules in the digit direction, the line and digit directions respectively being associated with those of an image data store area of the pixel image memory. Means is provided for selecting one of the rule patterns stored in the rule pattern store means and moving it to the pixel image memory. In response to a command entered through an input device, desired one of the rule patterns is selected and only a desired length of the selected rule pattern is moved.

A data processing device having input means, pixel image memory means for storing data corresponding to data to be displayed and control means for storing a particular line in the pixel image memory means in response to a command entered through the imput means, said data processing device comprising:
- particular line pattern store means for storing basic patterns representative of a plurality of particular lines extending in a first direction and a plurality of particular lines extending in a second direction, the first and second directions corresponding respectively to vertical and horizontal directions of an image data store area of the pixel image memory means;
- particular line pattern transfer means including pattern selecting means for selecting one of the basic patterns stored in said particular line pattern store means and including moving means for moving the selected basic pattern from said particular line pattern store means to the pixel image memory means;
- and
- position control means for positioning said selected pattern by storing the start address of the selected pattern, storing the start address of the line to be drawn in the pixel image memory means and causing the selected pattern to be moved into the pixel image memory means at sequential memory positions contiguous with the start address in memory.
