Title: Device and method for controlling printing head
Inventor: TAKAHASHI TORU
IPC: B41J25/308
Filed: 1991-12-24
Abstract: PURPOSE:To enhance precision in the setting of a gap between the tip of a printing head and the upper face of a printing blank form. CONSTITUTION:A stepping motor 11 is controlled on the basis of a command of rotation, a command of the direction of rotation and a command of strong excitation time sent from a command part 20 for rotation of a motor. In this case, when a printing head driven by the stepping motor 11 is moved at least to a platen side, the strong excitation time of the stepping motor 11 is controlled so as to be gradually reduced in accordance with the transfer rate from shaft of movement. In such a way, rotation disturbance of the stepping motor 11 accompanied with the quick change of driving torque at a time of changeover of impressed voltage can be minimized. The necessity for relaxing the step-out decision value more than required amount can be obviated. Precision in the setting of a gap between the printing head and the upper face of the printing blank form can be enhanced.

Filed: 1998-12-02
Abstract: PROBLEM TO BE SOLVED: To obtain a primitive moving method which facilitates positioning operation for a primitive by rotating the primitive by a conversion matrix and aligning the primitive with a space feature point. SOLUTION: To move the primitive to an arbitrary position in an arbitrary direction, a three-dimensional model generating tool is provided with a two-point matching and moving function. The two-point matching movement is a function for aligning two points on the primitive with an arbitrary point in a space. When two points (a) and (b) and space feature points a' and b' at movement destination are specified from the primitive to be moved, the quantity of parallel movement for putting the points (a) and (a') one over the other is found. The primitive is moved in parallel by using the parallel movement quantity. Then a conversion matrix for matching segments ab and a'b' with each other is found. The primitive is rotated by the conversion matrix. Then the primitive is aligned with the space feature point.  Thus, the parallel movement and rotation are performed at the same time to reduce a manipulated variable for primitive application.
