Abstract

The electronic typewriter with a carriage supporting a front wheel, has a sentence memory and display, for word processing. A print pressure table controls hammer duration (using a counter) depending on the character size, for uniform print density. A print pitch table controls print pitch, and ribbon feed (using a counter), according to character width. The front wheel can be exchanged according to character size/pitch, the table outputs being multiplied by coefficients depending on the wheel to reduce memory size. Feedback through an RC circuit is used near the target position in positioning the front wheel, and also the carriage. Carriage position is indicated on one of three scales according to pitch selected. Sheet feed can be controlled (using a counter) from the keyboard, via the sentence memory. A counter can scan the keys, a two bit latch corresponding to an actuated key being set to prevent repeated output of the corresponding count, the latch being then decremented on each scan. The display has a secondary character generator for characters not common to all countries.
