Abstract
Abstract In an ink liquid supply system for an ink jet system printer, an ink liquid reservoir, an air trap, a pump, an air chamber and an electromagnetic cross valve are made of resin blocks. Conduit means associated with the above-mentioned elements are formed in said resin blocks, whereby the elements are communicated with each other when the resin blocks are fixed to each other.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
160 words
In an ink liquid supply system for an ink jet system printer which emits ink droplets from a nozzle toward a record receiving member, selectively deflects said ink droplets by a deflection means, and prints desired symbols on said record receiving member with said deflected ink droplets, said ink liquid supply system being provided with an ink liquid reservoir for containing the ink therein and a pump for supplying the ink liquid from said ink liquid reservoir to said nozzle, the improvements comprising: a modular assembly including at least one synthetic resin base block; internal conduit means formed in said base block and terminating at the surfaces thereof in connectable configurations; ink supply system components mounted on said base block at selected ones of said connectable configurations; said components being interconnected through said conduit means internally of said base block; and external connecting means on said base block for interconnecting said modular assembly into a said ink jet system printer.
Claim 2
Dependent Claim
160 words
In an ink liquid supply system for an ink jet system printer which emits ink droplets from a nozzle toward a record receiving member, selectively deflects said ink droplets by a deflection means, and prints desired symbols on said record receiving member with said deflected ink droplets, said ink liquid supply system being provided with an ink liquid reservoir for containing the ink therein and a pump for supplying the ink liquid from said ink liquid reservoir to said nozzle, the improvements comprising: a modular assembly including at least one synthetic resin base block; internal conduit means formed in said base block and terminating at the surfaces thereof in connectable configurations; ink supply system components mounted on said base block at selected ones of said connectable configurations; said components being interconnected through said conduit means internally of said base block; and external connecting means on said base block for interconnecting said modular assembly into a said ink jet system printer.
Claim 3
Dependent Claim
94 words
The invention defined in claim 1, wherein said ink supply system components in said modular assembly include: an ink reservoir; an ink pump for taking ink from said reservoir having an intake interconnected therewith through a said base block; series connected filter means, accumulator means and control valve means fed by said pump means and mutually interconnected one with the other through a said base block; and coupling means in said modular assembly for interconnecting said control valve means with said ink reservoir and the said ink nozzle in said ink jet system printer.
Claim 4
Dependent Claim
42 words
The invention defined in claim 2, wherein said ink liquid reservoir and said pump are mounted on a common base block; and wherein said series connected filter means, accumulator means and control valve means are mounted on a second common base block.
Claim 5
Dependent Claim
46 words
The invention defined in claim 2, wherein said ink liquid reservoir and said pump are mounted on respectively individual base blocks each having said internal conduit means therein; and said base blocks being interconnected to communicate said pump means with said reservoir through internal conduit means.
