However, in the conventional parts supply apparatus, if the vibration of the straight rail is weak or the vibration time is short, the parts will remain between the straight rail and the part receiving section, resulting in an incomplete delivery state. There is When the reciprocating means is actuated while such a part is in an incomplete delivery state, the part is caught between the linear rail portion and the part receiving portion which moves away from it. Therefore, the conventional parts supply apparatus has a problem that the parts are likely to be incompletely delivered to the parts receiving section, and the parts cannot be supplied to the next process. Also, in order to solve this problem, it is conceivable to install an arrival confirmation sensor that detects whether or not the parts have been delivered to the parts receiving section in the correct posture. There was also the problem of becoming
