Abstract
Abstract An optical recording device for producing images as a whole at a predetermined scale size includes a beam oscillator for producing a beam, a scanner for line-scanning the beam produced by the beam oscillator, a recording mechanism for receiving the line-scanned beam in the form of a scanned spot and for recording an image formed by the scanned spot, and a variably sized aperture for receiving the beam and determining the size of the scanned spot.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
90 words
An optical recording device for printing scanned images as a whole at a predetermined scale size comprising: a beam oscillator for producing a beam; scanning means for line-scanning the beam produced by the beam oscillator; means for receiving the line-scanned beam in the form of a scanned spot and for recording an image formed by the scanned spot; and aperture means for varying the size of said line-scanned beam and thereby varying the size of printing dots formed by said scanned spot to enhance resolution of a printed scaled image.
Claim 2
Dependent Claim
90 words
An optical recording device for printing scanned images as a whole at a predetermined scale size comprising: a beam oscillator for producing a beam; scanning means for line-scanning the beam produced by the beam oscillator; means for receiving the line-scanned beam in the form of a scanned spot and for recording an image formed by the scanned spot; and aperture means for varying the size of said line-scanned beam and thereby varying the size of printing dots formed by said scanned spot to enhance resolution of a printed scaled image.
Claim 3
Dependent Claim
57 words
An optical recording device as claimed in claim 1, including control means for changing the size of the aperture means according to a scale factor set for the image to be formed so that the scanned spot size is set to be the same scale size as the predetermined scale size of the image as a whole.
Claim 4
Dependent Claim
32 words
An optical recording device as claimed in claim 1, including control means for changing the size of the aperture means independent of the scale factor set for the image to be formed.
Claim 5
Independent Claim
71 words
A method of printing scanned images as a whole at a predetermined scale size comprising: generating a beam; line-scanning the beam onto a recording material in the form of a scanned spot; varying the size of the scanned spot and printing dots formed by said scanned spot in accordance with a predetermined scale size of the recorded image as a whole to thereby enhance the resolution of the printed scaled image.
Claim 6
Independent Claim
71 words
A method of printing scanned images as a whole at a predetermined scale size comprising: generating a beam; line-scanning the beam onto a recording material in the form of a scanned spot; varying the size of the scanned spot and printing dots formed by said scanned spot in accordance with a predetermined scale size of the recorded image as a whole to thereby enhance the resolution of the printed scaled image.
Claim 7
Dependent Claim
35 words
The method of claim 4 wherein the step of determining the size of said scanned spot is carried out by controlling an optical aperature through which said beam passes prior to forming the scanned spot.
