发明名称 Sheet feed device for a selectable print speed image forming device having a time delayed pick-up roller
摘要 In a sheet feed device for image forming equipment, a sheet feed section and a register section are each provided an exclusive drive arrangement. The sheet feed section starts feeding a sheet toward the register section in response to a feed start signal generated in an image forming section. The time for causing the sheet feed section to stop feeding a sheet or the time for causing the register section to start driving the sheet is delayed in matching relation to a print speed. As a result, the sheet feed section provides a sheet with a sufficient slack while the register section brings the sheet into accurate register with an image and can change the position of an image on the sheet in the top-and-bottom direction.
