PROBLEM TO BE SOLVED: To store information data without reserving/releasing area in a memory and to store the information data, even if a reception speed of a multi-frame signal is fast. SOLUTION: A received data storage control section 1 stores received data included in a multi-frame signal to a storage memory 3 every time it receives the data, compares information data consisting of the received data received this time with the information data received precedingly and aborts the information data received this time, by overwriting information data which is to be received next on the information data received this time, when they are identical. A received data read analysis section 2 confirms the sequence of the information data that are stored in the storage memory 3 and received precedingly and writes a head storage address of the information data received precedingly to the storage memory 3 to an analysis end management table 4, when the sequence is normal.
