Abstract: A first construction of a tray for electronic parts according to the present invention is provided with an engaging cut-out corner portion which is formed by cutting a corner portion of a table-like flat portion which is arranged diagonally with respect to a-cut-out corner portion. A second construction of a tray for electronic parts according to the present invention is provided with a pawl engaging protruding portion which is formed on a step-like peripheral edge portion above a cut-out portion. In a third construction of a tray for electronic parts according to the present invention, when two trays are stacked up so that the top faces thereof face each other, an engaging first-shaped protrusion which is formed around a predetermined pocket of one tray engages an engaging second-shaped protrusion which is formed around a predetermined pocket of the other tray.

Abstract: A tray (1) has an upper surface (3) an upper surface provided with a plurality or pockets (10) for containing parts (50) in a regular, longitudinal arrangement at a predetermined pitch in a single row. The tray (1) has a pair of longitudinal first side surfaces (6A, 6B), and teeth (30) are arranged at equal intervals on the first side surfaces (6A, 6B). Pins (35) driven by a linear driving mechanism are fitted in grooves (38) between the adjacent teeth (30) to feed the tray (1) accurately in the longitudinal direction. A tray assembly of a desired capacity can be formed by combining a necessary number of the trays (1) in a transverse arrangement by engaging the teeth (30) of the tray (1) with the grooves (38) of the adjacent tray (1).

Abstract: A parts transporting tray (1) has a rectangular body, a plurality of parts receiving pits (6) formed in the upper face of the body, rows of detention means (2) each formed along one of perimeters of the body such that the adjacent trays can engage one with another, and a locking means (5) for keeping engaged the detention means of the adjacent trays. Each row consists of an upper and lower series of recesses (3) and protrusions (4) alternating one another at a constant pitch and being of a half thickness of the body. The protrusions on one perimeter are staggered with respect to those on the other perimeter, and each protrusion having a hooking portion (4a) facing transverse sides of the tray's body. The protrusions on one tray can loosely fit in the recesses on the other tray, and the trays are caused to slide relatively so that the protrusions on the neighboring trays engage with the recesses when a desired number of the trays are disintegratively connected one to another.

Abstract: A metal pallet of this invention comprises a plurality of longitudinal frames each including a pair of metal plate members each having a plurality of furrows formed along the longitudinal direction thereof and a plurality of support members interposed between the metal plate members to couple the same vertically, the longitudinal frames being arranged parallel to one another, and a plurality of transverse frames each having a plurality of furrows formed along the longitudinal direction thereof and arranged parallel to one another on the upper surfaces of the longitudinal frames at right angles thereto.
