A POS (Point Of Sales) system which employs a purchased commodity accommodating and transporting apparatus having a self scanning function is improved in that a total amount of money for commodities loaded on a shopping cart or in a shopping basket or unit prices of the individual commodities can come to a knowledge of a customer before the commodities are transported to a settlement POS terminal thereby to prevent possible shopping of an amount of money greater than an estimate to allow smooth shopping and that commodities are printed in a sorted condition for different groups to facilitate confirmation of purchased commodities by a customer. A display section is provided on the purchased commodity accommodating and transporting apparatus and displays the prices of commodities obtained by retrieval of a commodity price file in accordance with commodity code information read by a commodity code reading section and a total value of the prices of the commodities.

An address extension system is provided for generating a physical address by summing a segment starting point address and an offset. Conventionally, the content of a segment register is shifted by a predetermined amount and summed to the offset, and the address space and the segment starting point address are fixed. In contrast, the present address extension system includes a register for storing shift amount data and the shift amount is set in the register and shifted. An address extension system is also proposed wherein the shift amount is written in a predetermined bit of the segment register. As a result, the address space can be extended and the segment starting point address can be arbitrarily set.
