Abstract
Abstract A first and second filing apparatus comprises a main memory, a first time-division reading circuit for reading the data to output plural sets of data, a semiconductor memory, a second time-division reading circuit, a transmission circuit, and a control circuit responsive to external signal for transmitting desired data from the main memory when transmission frequency is low level. When the frequency exceeds a given value, first apparatus copies the data in the semiconductor memory. In the second apparatus, at every given interval data is stored in the semiconductor memory in order of the frequency. A third apparatus comprises a main memory, a reading circuit, a distribution circuit, transmission circuit, and a control circuit. When the frequency exceeds a given level, the control circuit receive the demand signal but waits until a given interval has passed or given number of receiving demand signals then the distribution circuit distribute a data to plural channel of transmission circuit. A fourth filling apparatus comprises plural main memories and the time-division reading circuits, and a control circuit for copying data in one main memory to other main memory when transinission frequency exceeds a given level.
