<p>PURPOSE:To enable the deletion, addition, etc. of the data in memories to be made easily with no limitations by providing an input memory which stores the input data from a keyboard and a correction-output memory which corrects the input data and outputs the data to an external memory. CONSTITUTION:A working memory consists of a correction-output memory 1 and an input memory 2. The data encoded in a keyboard circuit part 4 are successively stored into the memory 2 from its top address. When the memory 2 gets full, the data inputting is inhibited and the entire content of the memory 2 is moved into the memory 1, after which the inputting of the data is permitted. After the memory 1 is made full, the data are outputted to an external memory 3. A bignning code is beforehand stored in the last address of the memory 1 and an end code in the address next to the last of the memory 2. The deletion of the data is accomplished by carrying the data from the first address up to the end code of the data to be deleted, and the addition of the data is accomplished by carrying the data up to the beginning code before the address to be interrupted with the data by 1 word then storing the data to be added.</p> |
