<p>PURPOSE:To feed recording sheets of paper one after another without impairing the paper quality by providing possibility of taking out in the direction perpendicular to the sheet feeding, and making disengagement of heaving of a bottom plate and separation of a feed roller upward simultaneously at the time of taking out. CONSTITUTION:When a sheet feed cassette C is set in the accommodation position, a boss 31 turns an operational lever 9 clockwise, and meantime a step 33 moves clutch-A 24 in the direction of pressing. The power system is actuated when a light shutting plate 32 changes over a photo-sensor S2 into Off, and the clutch begins rotating in the specified direction. As a result, a heave lever 21 heaves a bottom plate 30 to put the recording sheets P in the inclined condition. On the other hand, a feed roller 1 sinks with rotation of the operational lever 9 to come in contact with the oversurface of the recording sheets P, but is pushed back by the rise of the recording sheets P due to heaving of the heave lever 21, and the feed roller 1 maintains its transporting attitude while held at the specified pressure contacting angle in the position where a light shutting plate 8A has put a photo-sensor S1 in Off.</p> |
