Abstract: PURPOSE: To enhance the process efficiency of the computer as well as to reduce the queuing time for the terminal unit to the process request by providing the scanner which performs scanning via the clock supplied and detects the process request.  
     CONSTITUTION: Scanner 6 carries out the cyclic counting via clock 5 to first turn line 6a-1 "H" against buffer 4-1 and then to have inquiry for the presence or absence of the process request. In case no process request exists, scanner 6 is counted up to turn next line 6a-2 "H". However, in case the process request exists and buffer 4-2 is set, line 4b is turned "H". And control circuit 8  transmits the "H" pulse to line 8a and loads the address corresponding to buffer 4-2. In case buffer 9 is idle, the address of buffer 7 is shifted to buffer 9 to make buffer 7 idle and then to repeat the above mentioned action. The scanning is carried out automatically at data input device 2, meanwhile computer 1 can progress the data process. Thus, the efficiency can be enhanced for the program process.
