Title: Image recording method
Inventor: SAWANO MITSURU
IPC: B41J2/35
Filed: 1991-07-16
Abstract: PURPOSE:To provide an image recording method designed to reduce as best as possible the influences of mixing of colors when monochromatic images are overlapped in printing. CONSTITUTION:The density of a color to be recorded to an image already recorded on a thermosensitive recording material 12 is predicted from the actually-measured value of a densitometer 28. When the predicted image density is not larger than the density of the generating color measured or expected from the image data to be recorded, recording is not carried out. If the density of the generating color expected from the image data to be recorded is larger than the predicted density, the image data to be recorded is corrected to lessen the recording energy so as to make the density of the image to be recorded equal to the density of the generating color expected from the image data to be recorded. Accordingly, the increase of the image density for every recording time is prevented and mixing of colors can be restricted to be minimum.

Abstract: PROBLEM TO BE SOLVED: To reduce the frictional loss and vibration of a shaft and to prevent noise incident to vibration by setting the number of grooves at the inside radial part of a porous bearing to satisfy a specific relationship with the number of poles of a motor magnet and armature. SOLUTION: The number of poles A of a motor magnet 1 is 8, the number of poles B of the armature having a coil 4 is 6, and the the number C of grooves 6 formed in the inside radial part 5 of bearing 2 is 7.
