PURPOSE: To enable efficient check-out by putting a commodity of the next customer on the supporting plane of a work station by that customer while performing the check-out transaction of a preceding customer.

CONSTITUTION: A work station 10 has two safety panels 12 and 14 and forms a place in L-shaped structure where an operator 18 enters. A passage instruction pole 22, to which a telephone set is fitted, is arranged at one end of L-shaped structure. There is a counter 28 adjacently to the pole 22 and this becomes a holding table for moving commodity from a shopping curt in order to wait check-out. While the operator 18 performs the processing of the preceding customer, the next customer can put his/her own commodity onto the counter 28, the operator can easily perform the check-out of purchased commodity of the next customer, and time can be saved.
