Abstract
Abstract A recording apparatus is shown in which serial printing of characters is achieved on a radiation sensitive print medium, by means of a radiation beam, modulated and deflected so as to scan a print area and to sensitize elementary spots serially on the print medium, each character being formed by the combination of said elementary spots.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
162 words
Recording apparatus for fixedly, serially, recording symbols by means of an electromagnetic beam incident upon a movable recording medium sensitive to said beam, along a printline on said recording medium, each symbol being formed by a combination of elementary spots, comprising, in combination, modulating means for forming said elementary spots by controlling the intensity of said beam reaching said recording medium, first means deflecting said beam at an angle with respect to said printlinE, said first means comprising a disc having a plurality of slots for causing said beam to scan said recording medium forming vertical sections of said symbols, second means deflecting said beam in the direction of the printline for causing said beam to scan said recording medium forming horizontal sections of said symbols and to shift said beam to different symbol positions along said printline, and synchronizing means for synchronizing said first and second deflection means and said modulating means to serially record elementary spots upon said recording medium.
Claim 2
Dependent Claim
162 words
Recording apparatus for fixedly, serially, recording symbols by means of an electromagnetic beam incident upon a movable recording medium sensitive to said beam, along a printline on said recording medium, each symbol being formed by a combination of elementary spots, comprising, in combination, modulating means for forming said elementary spots by controlling the intensity of said beam reaching said recording medium, first means deflecting said beam at an angle with respect to said printlinE, said first means comprising a disc having a plurality of slots for causing said beam to scan said recording medium forming vertical sections of said symbols, second means deflecting said beam in the direction of the printline for causing said beam to scan said recording medium forming horizontal sections of said symbols and to shift said beam to different symbol positions along said printline, and synchronizing means for synchronizing said first and second deflection means and said modulating means to serially record elementary spots upon said recording medium.
Claim 3
Dependent Claim
14 words
Recording apparatus as defined in claim 1 in which said recording medium is photosensitive.
Claim 4
Dependent Claim
14 words
Recording apparatus as defined in claim 1 in which said recording medium is thermosensitive.
Claim 5
Dependent Claim
34 words
The recording apparatus of claim 1, wherein said recording medium is coated with a toner, and wherein said toner is adapted to be fixed to said medium by said beam at said elementary spots.
Claim 6
Dependent Claim
51 words
The recording apparatus of claim 1, wherein said recording medium comprises a print receiving medium and a transfer medium proximate thereto, wherein said elementary spots are recorded on said transfer medium, and further including means for transferring the pattern of said spots from said transfer medium to said print receiving medium.
Claim 7
Dependent Claim
51 words
The recording apparatus of claim 1, further including a storage member for storing data representing each symbol to be recorded along said line, and wherein said synchronizing means responds to the data in said storage member and to the instantaneous position of said beam for synchronizing said deflection and modulating means.
