PROBLEM TO BE SOLVED: To enable prevention of operation stop of an electronic component mounting device, by storing in a memory a value obtained by dividing a stored count value by a predetermined number of electronic components mounted on one printed wiring board, then retrieving the minimum value thereof, and sequentially displaying the minimum value on a monitor. SOLUTION: A signal outputted from an electronic component feed detection sensor every time an electronic component is mounted onto a printed wiring board 3 is sequentially subtracted from a first memory at a memory address selected in accordance with a BCD code. Then, a quotient by a predetermined number of electronic components mounted on one printed wiring board from the same component cassette 68 is calculated, and the result thereof is stored in a second memory corresponding to the address. The minimum value of the result is retrieved and sequentially outputted to a monitor 16. Thus, replacement of electronic components can be efficiently carried out by displaying the number of remaining electronic components. |
