摘要:
In a feed roller for mixing a developer and feeding it to a developing roller, a first mixing wing (40) parallel to a rotating shaft (43) is provided, a second spiral-shape mixing wing (41) is diagonally provided in a manner to cross the first wing (40), and a spiral-shape groove (42) for feeding a powder is formed on the one side located on the forward section with respect to rotating direction and being the powder scraping-up side of the both sides of said second mixing wing (41), along said second mixing wing (41), so as to enhance the feed performance, lateral-mixing performance and lateral-feed performance of the feed roller.
摘要:
An exposure apparatus having a first mirror frame movement hampering means (47) for hampering the movement of a first mirror frame (4) in the exposing direction. The first mirror frame movement hampering means (47) comprises a closure (50) mounted on an operating opening (44) on the main body and a movement hampering member (52) mounted on the closure (50) and positioned near a linking portion (36) of a driving device (26) for the first mirror frame (4) and at a position at which it can interfere with movement of the first mirror frame in the exposing direction. The movement hampering member (52) is mounted on the closure (50) such that its position is adjustable freely within a predetermined range in the direction of reciprocating movement of the first mirror frame (4).

The present invention relates to a device for driving optical units for scanning a manuscript and in the going travel of the optical units (10, 14) they are driven by means of a first pulse motor (43) exhibiting the low-noise and high-torque characteristics within the revolving range in the going travel while in the returning travel of the optical units (10, 14) they are driven by means of a second pulse (45) motor exhibiting the low-noise and high-torque characteristics within the revolving range in the returning travel, whereby not only the optical units (10,14) can carry out the desired travel in both the going travel and the returning travel but also the noises generated during the travel of the optical units (10, 14) can be reduced as far as possible.
