The present invention eliminates or suppresses slipping of a board with a simple configuration. A conveyer (20) is provided with: a transfer belt (21), which transfers printed boards (M) one by one in the transfer direction of the printed boards (M) from a transfer start position; a belt protrusion (24), which is provided on the transfer belt (21) such that the belt protrusion protrudes therefrom, and which prevents each printed board (M) from slipping by being in contact with the printed board (M); a board detection sensor (S), which is provided at the transfer start position, and which detects whether there is the printed board (M); a servo motor (23) that drives the transfer belt (21); and a CPU that controls the servo motor (23). The CPU starts to drive the servo motor (23) when the board detection sensor (S) detected the printed board (M), and until the printed board (M) is transferred from the transfer start position to a mounting position where an electronic component is mounted on the printed board (M), the CPU brings the belt protrusion (24) into contact with an end surface (DE) of the printed board (M), said end surface being in the downstream in the printed board transfer direction, then, the CPU stops driving the servo motor (23) when the printed board (M) is transferred to a mounting position. |
