Title: Scanning optical system for image scanning recorder
Inventor: WAKIMOTO ZENJI
IPC: G02B13/00
Filed: 1988-04-20
Abstract: PURPOSE:To reduce an aberration and to obtain high resolving power, even if the effective scanning length is enlarged, by placing a galvanomirror in the vicinity of a focal position of a concave mirror, constituting the concave mirror of a back mirror, or placing a null lens by turning its concave surface to the galvanometer, at this side of the reflecting surface side of the concave mirror. CONSTITUTION:A galvanomirror 8 is used as a deflector, placed so that a value which has subtracted a distance between the final surface of an image forming lens 7 and the galvanomirror 8 from a distance between the final surface of the image forming lens 7 and an image forming point by its lens 78 become roughly equal with the focal length of the concave mirror 15, and the curvature of image becomes extremely small thereby. Also, a back mirror is used as the concave mirror 15, or a null lens is provided additionally at this side of the concave mirror 15, and a coma aberration and an astigmatism generated in the reflecting concave surface are corrected. In such a way, even if the effective scanning length is enlarged enough, a spherical aberration is obviated to the extent that is can be disregarded, and also, this system has high resolving power, and can perform easily the correction of aberrations, which cannot be performed easily by that which uses an ftheta lens.

Inventor: SAITO MIE
IPC: H04N1/411
Filed: 1986-04-30
Abstract: PURPOSE:To shorten the transmission time by providing a reception control means with a calculating part and a reception control part. CONSTITUTION:At the time of receiving the recording start instruction from a reception control part 10, a restoring device 13 reads out a compressed code 17 stored in a transmission buffer memory 12 and restores it to obtain an original picture signal 18. The picture signal 18 is sent to a picture recorder 14 to obtain a recorded picture. Since the recording start is decided in accordance with the number of scanning lines stored in the transmission buffer memory 12, the code consumption time is calculated in a calculating part 11 and is made constant. The best value is easily calculated in accordance with the transmission speed and the compression rate, and the transmission buffer memory 12 is prevented from being empty even if the number of generated codes is changed by the change of the compression rate, and unnecessary codes are not stored. Thus, the transmission time is shortened.
