<p><P>PROBLEM TO BE SOLVED: To enable an operator to easily perform state checking operation of detectors before or after maintenance operation, and to evade malfunction of the detectors after the maintenance operation as much as possible. <P>SOLUTION: On a display part 70A formed on the upper surface of a grip 70 of a component supply unit 6, 7-segment display units 77 are formed as a display means correspondingly to right and left lanes. A lower segment 91 is blinked at a short interval in accordance with the feeding operation of a storing tape C. By checking the display state of the lower segment 91, an operator can check the operation states of seam detectors 102, i.e. whether the seam detectors 102 are normally operated or not. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
