PURPOSE:To enable accurate feeding and recovering of a tray with a simple construction by loading and unloading a microplate depending on own gravity of a pawl. CONSTITUTION:Trays are tiled up on a holding frame of a feeder and an operation button is depressed. A motor 32 starts to lift a push up plate 29. The plate 29 turns a pawl plate and reaches the top pushing it open released from the engagement with the trays. As with the rotation of a crank plate 33, the push up plate 29 starts lowering holding the trays, the pawl plate turns upward by its own gravity inserting the tip thereof between retaining projections of the trays on the lowest and subsequent stages and passes a pawl retained on the push up plate 29 separating from stacked matters. Then it retains the subsequent trays to hold the whole of stacked matters. The tray separated is shifted with a shifting mechanism onto a push up plate of a recovery apparatus with an additional operation and stacked thereon driven with a thrust device. |
