PROBLEM TO BE SOLVED: To provide a part feeder of layout structure which feeds an electronic part arranged in a tray used in a part mounting device and is capable of absorbing a deformation in a guide rail caused by a temperature change. SOLUTION: Tray plates 2 where a tray is fixed respectively are housed in layers in a tray magazine, and when the tray plate 2 is drawn out through a draw part, a guide rail 21 on which the tray plates 2 are placed is mounted through an elliptical holes 24 so as to absorb expansion/shrinkage in the guide rail 21 caused by a temperature change, a stepped part 22a slightly longer than the thickness W of the guide rail 21 is provided to mounting stepped bolts 22 respectively so as to produce a gap S for mounting the guide rail 21. |
