<p>PURPOSE:To reset a cursor to an arbitrary location with one switch operation by resetting a display cursor to the reset coordinates of a coordinate register based on a reset pulse with a control part. CONSTITUTION:The outputs of an X direction moving counter 2 and a Y direction moving counter 3 are transmitted also to a coordinate register 8 and when a trigger pulse is inputted by a trigger switch 6, the count values of X and Y are latched here. Reset coordinates which is the output of the coordinate register 8 are transmitted to a control part 5 and when a reset pulse is inputted from a reset switch 7 to the control part 5, a cursor can be reset to the reset coordinates outputted from the coordinate register 8. Thus, the cursor is reset to an arbitrary position with hardware.</p> |
