PURPOSE:To decrease the number of operation members and to reduce the whole device in size and the cost thereof by providing control means for operating plural sheet feed means and the second sheet feed means with a designated relation therebetween. CONSTITUTION:Sheets fed out from the upper and lower sheet feed cassettes are transported to a transfer portion by a sheet feed roller 22. A lever 26 is co-operated with clutch 24 to check the transmission of turning force to a roller 17 when a solenoid 31 is not operated. As at this time, the lever does not act upon clutches 23, 25, the turning force is transmitted to rollers 16, 22. When a solenoid 32 is operated, a lever 27 transmits the turning force to the roller 16, and checks the transmission of turning force to the rollers 17, 22. Subsequently, when the solenoid 31 is operated, and the solenoid 32 is not operated, the transmission of turning force to the rollers 16, 17, 22 is reversed. Accordingly, the rollers 16, 17, 22 can be controlled by combination of operation and non- operation of the solenoids 31, 32 of the leaves 26, 27 to feed out sheets in one cassette and transport same to a transfer portion. Thus, the rollers can be controlled by two operating members and two levers, so that the number of parts can be decreased. |
