Title: Sheet carrying device and image forming device
Inventor: WAKAHARA SHINICHIRO
IPC: B65H9/14
Filed: 1994-10-07
Abstract: PURPOSE: To register sheets with a high accuracy even if the sheets are carried at high speed by arranging plural cross-sectional semicircular rollers on the driving side of a sheet carrying means arranged upstream in the sheet carrying direction than a registering means. CONSTITUTION: When a sheet detecting sensor 4 detects the tip of sheets S separated and fed from a paper feeding separating part 3, after rotating so as to be driven always in the same positional relationship from the sheet tip, semicircular rollers 5a and 6a stop the sheets S in a non-holding condition, that is, in a position where notch surfaces of the driving side semicircular rollers 5a and 6a are opposed to driven rollers 5b and 6b. By constituting a device in this way, when a skew is corrected by active registering roller pairs 7, the sheet rear end side is not restricted by the roller pairs, and sheet carrying speed becomes fast, and even when an inter-paper space is not present, the sheets S can be continuously carried at the smallest interval while maintaining skew correcting accuracy with high accuracy.
