Processing apparatus comprising a cassette member temporarily swingable to vertically hold a plurality of substrates

Claim 2

A processing apparatus comprising a processing chamber defining a processing hollow space, means coupled to said processing hollow space for processing a sheet-like unprocessed substrate to provide a processed substrate, an inlet chamber defining an inlet hollow space, a first cassette member for holding a stack of unprocessed substrates in said inlet hollow space with each unprocessed substrate kept substantially parallel, means for transferring one substrate from said stack at a time into said processing chamber, an outlet chamber defining an outlet hollow space, means for transferring the processed substrate from said processing hollow space into said outlet hollow space, and a second cassette member for receiving the transferred substrate in said outlet hollow space as a stack of processed substrates with each processed substrate kept substantially parallel, wherein the improvement comprises moving means coupled at least to a selected one of said first and said second cassette member for reversibly moving the selected cassette member between a home position and a temporary position, said selected cassette member holding the substrates with each substrate kept substantially horizontal and vertical when moved to said home and said temporary positions, respectively.

Claim 3

A processing apparatus comprising a processing chamber defining a processing hollow space, means coupled to said processing hollow space for processing a sheet-like unprocessed substrate to provide a processed substrate, an inlet chamber defining an inlet hollow space, a first cassette member for holding a stack of unprocessed substrates in said inlet hollow space with each unprocessed substrate kept substantially parallel, means for transferring one substrate from said stack at a time into said processing chamber, an outlet chamber defining an outlet hollow space, means for transferring the processed substrate from said processing hollow space into said outlet hollow space, a second cassette member for receiving the transferred substrate in said outlet hollow space as a stack of processed substrates with each processed substrate kept substantially parallel, wherein the improvement comprises moving means coupled to at least a selected one of said first and said second cassette members for reversibly moving the selected cassette member between a home position and a temporary position, said selected cassette member holding the substrates with each substrate kept substantially horizontal and vertical when moved to said home and said temporary positions, respectively; said selected cassette member comprising a cassette for holding the stack of substrates and having a specific point not lower than the center of gravity of the selected cassette member moved to said home position together with the stack of substrates, wherein: said selected cassette member further comprises first and second substantially horizontally aligned rod members fixed to said cassette above said specific point when said selected cassette member is moved to said home position; said moving means comprising: driving means for reversibly vertically driving said first and said second rod members; and a limitation bar horizontally protruded so that said first rod member is urged against said limitation bar while it is driven upwardly by said driving means; said selected cassette member being put into and out of said temporary position when said first rod member is driven upwardly into contact with said limitation bar and downwardly out of contact with said limitation bar, respectively.

Claim 4

A processing apparatus comprising a processing chamber defining a processing hollow space, means coupled to said processing hollow space for processing a sheet-like unprocessed substrate to provide a processed substrate, an inlet chamber defining an inlet hollow space, a first cassette member for holding a stack of unprocessed substrates in said inlet hollow space with each unprocessed substrate kept substantially parallel, means for transferring one substrate from said stack at a time into said processing chamber, an outlet chamber defining an outlet hollow space, means for transferring the processed substrate from said processing hollow space into said outlet hollow space, a second cassette member for receiving the transferred substrate in said outlet hollow space as a stack of processed substrates with each processed substrate kept substantially parallel, wherein the improvement comprises moving means coupled to at least a selected one of said first and said second cassette members for reversibly moving the selected cassette member between a home position and a temporary position, said selected cassette member holding the substrates with each substrate kept substantially horizontal and vertical when moved to said home and said temporary positions, respectively; said selected cassette member comprising a cassette for holding the stack of substrates and having a specific point not lower than the center of gravity of the selected cassette member moved to said home position together with the stack of substrates, wherein: said selected cassette member further comprises first and second substantially horizontally aligned rod members fixed to said cassette above said specific point when said selected cassette member is moved to said home position; said moving means comprising: driving means for reversibly vertically driving said first and said second rod members; and a limitation bar horizontally protruded so that said first rod member is urged against said limitation bar while it is driven upwardly by said driving means; said selected cassette member being put into and out of said temporary position when said first rod member is driven upwardly into contact with said limitation bar and downwardly out of contact with said limitation bar, respectively.

Claim 5

A processing apparatus as claimed in claim 2, wherein said first rod member comprises: a horizontal rod having a first and a second end and fixed at said first end to said cassette in alignment with said second rod member; and an arm extended perpendicularly from said second end in a horizontal plane when said selected cassette member is put in said home position; said arm being urged to said limitation bar while said first and said second rod members are moved upwards by said driving means.

Claim 6

A processing apparatus as claimed in claim 3, wherein said driving means comprises: holding means for rotatably holding said rod and said second rod member; and guide means for guiding said holding means for vertical movement of said holding means.

Claim 7

A processing apparatus as claimed in claim 4, wherein said guide comprises: a threaded rod vertically extended transversely of said limitation bar; and means for rotating said threaded rod; said holding means having a threaded inside surface engaged with said threaded rod.
