In a speech synthesizer, speech speed is selectable by a switch which selects the number of repetitions of a basic waveform or equivalent parameters thereof.

Speech synthesizer with variable speed of speech

An electronic calculator with a dot matrix display panel capable of displaying characters, symbols or other patterns is implemented with a central processor unit (CPU). More particularly, when the length of characters is in excess of the capacity of the display panel, those characters are shifted dot by dot on the display panel in the running fashion. Numbers are displayed digit by digit, preferably.

Dot matrix type running display panel for use in electronic calculators

A display device disclosed herein includes a dot matrix type liquid crystal display panel capable of displaying not only digits but characters in the form of a matrix. Digit of character information is stored within a memory forming part of a CPU and shifted digit by digit or character by character while the display device is in operation. In other words, the digits or characters are shifting or running at each given length of time. The present device makes it possible of displaying numerals, characters, symbols and the like of a length more than the capacity of the display panel.
