PURPOSE:To decrease display space in the display state, by achieving display of light emitting elements of key input inputting each commodity through the display on an ECR main body when an invertory is a preset number or lower and succeeding display until the commodity reaches the number of inventory. CONSTITUTION:With the operation of a set mode switch 16 of a mode switch 15 connected to a CPU8 of an ECR, numerical information inputted from a numerical information input means 1 is preset to an inventory storage area (a) and an inventory lower limit area (b) of a memory 10. At each registration, the transaction data from the means 1 is inputted to the CPU8 and the quantity as a result of the transaction is subtracted from the inventory of each commodity stored in the memory 10 and the result is compared with the content of the area (b), and the content stored in the area (a) is controlled with an input and output control means 12. In case of transaction control of the means 12, the inventory of the memory 10 decreased from the inventory lower limit is detected at a display designating means 18, and based on the result of detection, display means L1-Ln are displayed near a function key group 3. |
