Abstract
PURPOSE: To make small the size and make light in weight, by using the carriage drive motor or the print wheel drive motor as the drive source of the memory unit, reducing the drive source for the entire typewriter and various circuits attached to the drive source.
CONSTITUTION: The code signal corresponding to the key operated among a number of keys, is produced from the keyboard 21, and signal is outputted to the print hammer drive circuit 24 and the print wheel drive circuit 23 from the conrrol circuit 22 in response to this signal to turn the print wheel 4, desired character-element 5 is moved th the print position, and print operation is executed with the hammer 6. After that, signal is outputted to the carriage drive circuit 25, the carriage 2 is shifted by one character with the carriage drive motor 3, the signal is temperarily stored in RAM26, and the print data is stored in the magnetic disc 14 via the magnetic head 13 from RAM26. Further, as the drive source relatively interlocking with the head 13 and the disc 14, the drive motor 3 is used for small size and light weight for entire unit.
