WIPO Patent Application WO/2022/009458
Kind Code:

Abstract:
The present invention comprises: an opening/closing lid (16) that openably/closably covers an opening section provided in a region cover (23) covering a first region that constitutes a preprocessing device; a support arm (35) that connects to a support shaft (37) inside the first region and that is rotatably supported by the support shaft (37); and an openness retaining mechanism (30) that retains the support arm (35) such that the opening/closing lid (16) is retained in a fully open position when the distal end of the opening/closing lid (16) is at a position higher than a predetermined reference height, and that releases the retaining of the support arm (35) such that the opening/closing lid (16) moves to a fully closed position automatically when the distal end of the opening/closing lid (16) is at a position lower than the reference height, whereby the opening/closing lid (16) is retained such that the distal end is higher than the support-shaft (37) side in the fully open position and such that the support-shaft (37) side is higher than the distal end in the fully closed position, can be stably maintained in an open position, and can be moved to the fully closed position in accordance with urging from above.
