<p>PURPOSE:To obtain a miniature electronic apparatus featuring the simplified key operation by installing the key to supply the information, the mode key to give plural different meanings to the input information and the means to designate the memory address of the input information according to the operation of the mode key. CONSTITUTION:Input key 1A, 2B and 3C function to supply the figures or alphabet letters, and alpha1 and alpha2 show the mode keys. Thus, the input is designated for the figures or the alphabet letters by the operation of the mode keys. In case the data of ABC123 is supplied, key 1A is operated after pushing down key alpha1. As a result, the contents of counter cnt is turned to 1, and the code signal of alphabet A is supplied to memory MIB from input control part ICB. In the same way, the signals of B and C enter memory MIB via operation of key 2B and 2C. Then figure codes are memorized in sequence into memory MIA from input control part ICA through operation of key 1A, 2B and 3C in that order after push of key alpha2. After this, the characters and figures are displayed via display circuit DP through designation by the mode key.</p> |
