Abstract
Abstract Ink jet printer shiftable along a sheet recorder. The printer has conventional deflection plates or electrodes which, when energized, create an electromagnetic field corresponding to the shape of the indicia to be recorded and cause the spray of ink issuing from the head to be deflected to assume the configuration of the magnetic field. The head is moved along a record sheet traveling about a roll and is connected to its carrier by plug in connections, to enable cleaning or exchanging of the head and to avoid all solder connections. The plug-in connections are so arranged to prevent the plugging forces from being transmitted to the recording head.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
123 words
In an ink jet recording device, a carriage shiftable along a record sheet, support and guide means for said carriage, a recording head including an ink jet nozzle and a series of deflecting plates extending thereacross in horizontal and vertical directions, mechanical and electrical slidable plug-in connections between said recording head and carriage mechanically connecting said recording head to said carriage and electrically connecting said deflecting plates, said electrical connections being energizable to create electromagnetic fields along said deflecting plates in conformance to the form of the indicia to be recorded, and all of said plug-in connections being arranged to remove all damaging forces to said recording head when plugging said recording head in or removing said recording head for cleaning or replacing.
Claim 2
Dependent Claim
123 words
In an ink jet recording device, a carriage shiftable along a record sheet, support and guide means for said carriage, a recording head including an ink jet nozzle and a series of deflecting plates extending thereacross in horizontal and vertical directions, mechanical and electrical slidable plug-in connections between said recording head and carriage mechanically connecting said recording head to said carriage and electrically connecting said deflecting plates, said electrical connections being energizable to create electromagnetic fields along said deflecting plates in conformance to the form of the indicia to be recorded, and all of said plug-in connections being arranged to remove all damaging forces to said recording head when plugging said recording head in or removing said recording head for cleaning or replacing.
Claim 3
Dependent Claim
109 words
In an ink jet recording device, a carriage shiftable along a record sheet and having a socket at its upper end having an internal cylindrical wall, a recording head including an ink jet nozzle and a series of deflecting plates extending thereacross in horizontal and vertical directions, said internal cylindrical wall of said socket having spaced chambers leading therefrom for respective of said deflection plates and energizing contacts for said deflection plates, said socket and chambers forming slidable plug-in connections electrically connecting said deflecting plates to energize said deflecting plates to create electromagnetic fields along said deflecting plates in conformance to the form of the indicia to be recorded.
Claim 4
Dependent Claim
109 words
In an ink jet recording device, a carriage shiftable along a record sheet and having a socket at its upper end having an internal cylindrical wall, a recording head including an ink jet nozzle and a series of deflecting plates extending thereacross in horizontal and vertical directions, said internal cylindrical wall of said socket having spaced chambers leading therefrom for respective of said deflection plates and energizing contacts for said deflection plates, said socket and chambers forming slidable plug-in connections electrically connecting said deflecting plates to energize said deflecting plates to create electromagnetic fields along said deflecting plates in conformance to the form of the indicia to be recorded.
Claim 5
Dependent Claim

In an ink jet recording device, a carriage shiftable along a record sheet, A support and guide means for said carriage, a recording head including an ink jet nozzle and a series of deflecting plates extending thereacross in horizontal and vertical directions, slidable plug-in connections between said recording head and carriage providing electrical connections to said deflecting plates, energizable to create electromagnetic fields along said deflecting plates in conformance to the form of indicia to be recorded, said carriage having at least one rigid ink supply line, said recording head having an ink supply nipple in direct alignment with said ink supply line, and a resilient sleeve carried by said recording head on said nipple so arranged as to be plugged into said rigid ink supply line upon plugging in the recording head to provide a leak-proof connection between said supply line and the recording head.
Claim 8
Dependent Claim
146 words
In an ink jet recording device, a carriage shiftable along a record sheet, A support and guide means for said carriage, a recording head including an ink jet nozzle and a series of deflecting plates extending thereacross in horizontal and vertical directions, slidable plug-in connections between said recording head and carriage providing electrical connections to said deflecting plates, energizable to create electromagnetic fields along said deflecting plates in conformance to the form of indicia to be recorded, said carriage having at least one rigid ink supply line, said recording head having an ink supply nipple in direct alignment with said ink supply line, and a resilient sleeve carried by said recording head on said nipple so arranged as to be plugged into said rigid ink supply line upon plugging in the recording head to provide a leak-proof connection between said supply line and the recording head.
Claim 9
Dependent Claim
81 words
The ink jet recording device of claim 5, including means shifting the carriage along the line of the record sheet, means supporting and guiding the carriage for movement in a rectilinear path, wherein the recording head has a base supporting said recording head in elevated relation with respect to said base, and the carriage has a recessed portion conforming to said base and forming a receptacle for plugging in the ink supply and energizing connections to said recording head from above.
Claim 10
Dependent Claim
89 words
The ink jet recording device of claim 6, wherein the recessed portion of the carriage forms a receptacle for a multi-contact electric plug and bushing and forms a support for an ink supply line leading downwardly therefrom beneath said carriage adapted to have an ink hose plugged in from below, wherein a rigid fluid conduit leads upwardly from said fluid connection into said base, and wherein a connecting sleeve is provided for plugging in said fluid connection to said recording head upon plugging said recording head into said base.
Claim 11
Dependent Claim
59 words
