Abstract

PURPOSE: To make needless at all any complex interface such as giving and taking of data between plural number of microprocessors by enabling double control of a printing wheel motor and of the keyboard scanning by using a single microprocessor.
CONSTITUTION: After the speed A of a printing wheel motor having reached the level f3 through acceleration, the motor is rotated at a high normal speed, and then, while its speed being reduced to the level f1, the keyboard scanning (the timing of keyboard scanning B) is conducted. Since f1 is smaller than f2, which is the self- starting frequency of the motor, it does not occur that any false action is caused by the motor out of regulated order, even if the frequency and the width of time are changed due to the state of the keyboard scanning. It is true that the type-selecting time by the rotation of the printing wheel motor is somewhat reduced, but it is as little as about 20%. Therefore, it causes no great difficulty at all.
