PURPOSE:To store and display a receiving data with a simple circuit by writing a received parallel data to an address part which is subjected to increment by a sequential start pulse in synchronizing with a strobe signal and reading the signal by the operation of a manual display selecting switch group. CONSTITUTION:An address counter 1 is subjected to increment by a start pulse signal and an address is applied to an RAM4 through a multiplexer 3. An input data is written sequentially in the RAM4 through a display selecting circuit 5 in synchronizing with the strobe signal inputted alternately with the start pulse signal. After the end of data receiving, the display selecting switch group 2 is operated, a data is read from the RAM4 besed on the generated address and displayed on a display device 6.
