PURPOSE: To continuously transfer the data of plural bytes of discontinuous addresses which are stored in a memory in a simple constitution.

CONSTITUTION: The bits of a register 24 are increased and the start address of the storage position of the information data D1 stored in a memory means 12 is set in a 1st counter 20. Meanwhile the end address of the data D1 is set in a 1st register 21. Then the transfer of the data D1 is started by a control means 4, and the start address of the storage position of the 2nd information data D4 which are continuously transferred is substituted for the counter 20 from a 2nd register 22 during the transfer of the data D1. Then the end address of the data D4 is substituted for the register 21 from a 3rd register 23.
