Discription
Change in angle to prevent blurring. Refer to
Technical Report SP-1491.
Of the parts reported in Technical Report
SP-1540, only the inch line parts have been
eliminated.
The mylar reported in Technical Report
SP-1485, has been eliminated, and the lens
shaft holder has been changed to a single unit
type.
Change in shape of lens shaft holder in the
optical unit.
To prevent darkening of the rear edges of
copies made during reduction copy operations,
a sheet has been added to prevent the rear
edge of the copies from raising up.
To prevent blurring, the height of the brake
spring has been changed (7 ±0.1 → 6 ±0.5).
Refer to Technical Report SP-1544.

Lock sheets have been added to prevent
blurring.
Resistance has been added because the side
lamp occasionally does not illuminate due to
noise interference from the main motor during
manual feeding.
