PROBLEM TO BE SOLVED: To automatically obtain data comprising the product names and the selling number of sold products and to manage selling by transferring the products at speed by which the read visual field range of a bar code reader provided in a route for carrying out the products outside a machine can be read and outputting data which is read. SOLUTION: The bar code reader 1 for reading the bar code of the product is provided for the route carrying out the products to a product carry-out port from a product column and a product transfer part 2 for moving the products by which the read visual field range can be read is provided. When a bar code reader control part 11 receives a product carry-out command signal from a product carry-out control part 21, it sets the bar code reader 1 to be a standby state. When the bar code reader 1 senses the shift of the product into the read visual field range, the reading of the bar code is instructed. Bar code data read by the bar code reader 1 is transmitted to a communication control part 31 and it is outputted to a selling management computer 4 at an external part through a line 3. |
