PURPOSE:To prevent a thin pallet from projecting outside a frame by enlarging a range within which the pallet is capable of being positioned. CONSTITUTION:A pair of holding levers 11A, 11B capable of holding the blocks to be held, which are provided to be projected from the underside of a pallet, are arranged on an elevator frame 3 provided with roller conveyor devices 7, at a specified interval in the pallet conveying direction so that they can freely turn about a supporting pin crossing the pallet conveying direction at right angles. An interlocking link arm for turning the holding levers 11A, 11B on the mutually opposite directions is put in connection between both holding levers 11A, 11B, and also a motor-driven jack 13 for turning holding levers is connected to one side holding levers 11A through an interlocking shaft 12 and plural levers and links so that it can be freely on or off, and the holding levers 11A, 11B are set so that their upper ends at released positions are situated below the blocks to be held. |
