Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
52 words
A nozzleless ink jet printer comprising: a propagation element (1) having an edge (1c) to which ink is supplied and a propagating surface (1a) for leading a surface acoustic wave to said edge (1c); and surface acoustic wave generating means (2) for generating a surface acoustic wave in said propagating surface (1).
Claim 2
Dependent Claim
52 words
The nozzleless ink jet printer as claimed in claim 1, in which said propagation element (1) has edges (1j) to which ink is supplied provided for respective propagation paths on said propagation surface (1a), the width of each edge (1j) being smaller than the propagation width of the respective surface acoustic wave.
Claim 3
Dependent Claim
39 words
The nozzleless ink jet printer as claimed in claim 1, in which said propagation element (1) has a crack (1d) extending across said propagating surface (1a), and the edge (1c) of said crack (1d) is employed as said edge.
Claim 4
Dependent Claim
46 words
The nozzleless ink jet printer as claimed in one of the preceding claims, in which said propagation element (1) has an end face (1b) to which ink is supplied by surface tension, said end face (1b) forming an angle with respect to said propagating surface (1a).
Claim 5
Dependent Claim
32 words
The nozzleless ink jet printer as claimed in one of the preceding claims, further comprising ink collecting means (5c; 71), disposed in front of said edge (1c) for collecting excess ink droplets.
Claim 6
Dependent Claim
45 words
The nozzleless ink jet printer as claimed in claim 1, further comprising a belt-shaped ink bearer (44) in sliding contact with said edge (14c) in such a manner that said ink bearer (44) is movable in a direction of movement of a recording medium (S).
Claim 7
Dependent Claim
33 words
The nozzleless ink jet printer as claimed in one of the preceding claims, in which said propagation element (1) is longer than a recording region (S) and is arranged near a platen (P).
Claim 8
Dependent Claim
33 words
The nozzleless ink jet printer as claimed in claims 1 to 5, in which said propagation element (12) and surface acoustic wave generating means (22) are movably arranged (93) in a recording region.
Claim 9
Dependent Claim
39 words
The nozzleless ink jet printer as claimed in one of the preceding claims, in which said surface acoustic wave generating means (2) comprises at least one pair of comb-shaped teeth-interleaved electrodes (2a, 2a) formed on said propagating surface (1a).
Claim 10
Dependent Claim
29 words
The nozzleless ink jet printer as claimed in one of the preceding claims, in which said surface acoustic wave generating means comprises at least one wedge type vibrator (6).
Claim 11
Dependent Claim
43 words
The nozzleless ink jet printer as claimed in one of the preceding claims, in which bias exciting wide surface acoustic wave generating means and a plurality of surface acoustic wave generating means operating according to recording signals are arranged on said propagating surface.
Claim 12
Dependent Claim
46 words
The nozzleless ink jet printer as claimed in one of the preceding claims, comprising wide surface acoustic wave generating means (2) and a plurality of suppressing means (35) for attenuating unwanted parts of a surface acoustic wave generated by said wide surface acoustic wave generating means.
Claim 13
Dependent Claim
69 words
A nozzleless ink jet printer comprising: a propagation element (12) having a propagating surface (12a) for leading a surface acoustic wave to an edge (12c) thereof and an end face for leading ink to said edge by surface tension; and surface acoustic wave generating means (22) which is other than said propagation element (12), said surface acoustic wave generating means (22) being acoustically coupled to said propagation element (12).
Claim 14
Dependent Claim
45 words
The nozzleless ink jet printer as claimed in claim 13, in which said propagation element (12) is coupled to said surface acoustic wave generating means (22) in such a manner that said propagation element (12) is separable from said surface acoustic wave generating means (22).
