Abstract
A multibeam recording apparatus comprises a scanner for scanning a recording medium with a plural number of beams, a beam detector for producing detection signals in response to the incident of every beam on the detector, a distributor for distributing the detection signals and a controller for controlling the start of recording with the beams individually by means of the distributed detection signals.
Claims18
A beam recording apparatus using a plural number of beams, said apparatus comprising:
- means for scanning a recording medium with said beams;
- beam detection means for receiving said beams and producing detection signals in response to receipt of said beams;
- a beam selection member, associated with said detection means, through which only one of said beams of said plural number of beams can pass at one time to be incident on said detection means;
- means for distributing said detection signals;
- and
- means for controlling the start of recording with said beams individually by means of said distributed detection signals.
A beam recording apparatus using a plural number of beams, said apparatus comprising:
- means for scanning a recording medium with said beams;
- a plural number of gates for individually controlling the respective outputs of said beams;
- beam detection means for receiving said beams and producing detection signals, the output of said detection means being connected in parallel to said plural number of gates.
- means for counting the number of times a beam is incident on a predetermined position and for generating an output indicative thereof;
- and
- means for making said gates open in response to said detection signals and to the output from said counting means.
A beam recording apparatus using a plural number of beams, said apparatus comprising:
- means for scanning a recording medium with said beams at the same time;
- means for counting the number of times a beam is incident on a predetermined position;
- and
- means for detecting the state of said beams in accordance with on whether said counting means counts to a predetermined number of counts within a predetermined time.
A beam recording apparatus using a plural number of beams, said apparatus comprising:
- means for scanning a recording medium with said beams;
- means for receiving said beams and producing detection signals;
- means connected to said receiving and producing means for sequentially generating control signals for controlling said beams individually in response to said detection signals;
- and
- means for detecting the state of said beams in accordance with whether the number of said control signals generated by said generating and controlling means corresponds to the number of said plural beams.
A beam recording apparatus using a plural number of beams, said apparatus comprising:
- means for scanning a recording medium with said beams;
- means for counting the number of times a beam is incident on a predetermined position and for generating a predetermined signal in response to the value of the count, and
- means for controlling the scanning with said beams individually in accordance with the output signal of said counting means.
