Sheet feeding apparatus

A recording system comprising:

• feeding means including a pair of rollers forming a nip therebetween, each of said pair of rollers being rotatable in both directions, for selectively nipping and feeding a sheet in a first direction and a second direction opposite the first direction;
• a tray disposed downstream of said feeding means in the second direction to stack the sheet fed in the second direction by said feeding means;
• guide means for guiding the sheet, said guide means being disposed between said feeding means and said tray and being shiftable between a first position near said nip to direct the sheet from said tray toward the nip thereby to feed the sheet in the first direction by said feeding means, and a second position further away from said nip than said first position to permit advance of the sheet fed by said feeding means in the second direction to said tray;
• shifting means for selectively shifting said guide means between said first position and said second position, said shifting means including manually operated means for being moved by manual operation and converting means for mechanically converting a movement of said manually operated means to a shift of said guide means from the second position to the first position;
• drive transmission means for driving said shifting means, said drive transmission means including a frictional clutch including a pair of clutch members engageable with each other with a pressure for transmitting a drive force from a drive source to said shifting means, the pressure between said pair of clutch members decreasing when said shifting means shifts said guide means to the second position;
• and
• recording means for recording an image on a sheet fed by said first feeding means, wherein when the guide means is shifted to the first position, and a sheet is manually set on said tray and guided to the nip by said guide means, the sheet is fed in the first direction by said feeding means.

A recording system comprising:

• feeding means including a pair of rollers forming a nip therebetween for pinching a sheet, each of said pair of rollers being rotatable in both directions for selectively feeding the sheet in a first direction and a second direction opposite to the first direction;
• guide means for guiding the sheet, said guide means being shiftable between a first position near the nip to direct the sheet toward the nip thereby to feed the sheet in the first direction by said feeding means, and a second position further away from the nip than said first position to permit advance of the sheet fed by said feeding means in the second direction;
• recording means for recording an image on the sheet fed by said feeding means;
• and
• shifting means for selectively shifting said guide means between said first position and said second position, said shifting means including manually operated means for being moved by manual operation and converting means for mechanically converting a movement of said manually operated means to a shift of said guide means from the second position to the first position.

• a tray disposed downstream of said feeding means in the second direction to stack the sheet fed in the second direction by said feeding means;
• guide means for guiding the sheet, said guide means being disposed between said feeding means and said tray, said guide means including;
• a first guide member shiftable between a first position near to direct the sheet from the tray toward the nip thereby to feed the sheet in the first direction by said feeding means, and a second position further away from the nip than the first position to permit advance of the sheet fed by said feeding means in the second direction to the tray;
• shifting means for selectively shifting said first guide member between the first position and the second position, said shifting means including manually operated means for being moved by manual operation and converting means for mechanically converting a movement of said manually operated means to shift said first guide member from the second position to the first position;
• a second guide member for guiding the sheet;
• a third guide member having one side end connected to said second guide member and another end connected to said first guide member, said third guide member being shiftable in accordance with a shift of said first guide member;
• and
• drive transmission means for driving said shifting means, said drive transmission means including a frictional clutch including a pair of clutch members engageable with each other with a pressure for transmitting a drive force from a drive source to said shifting means, the pressure between said pair of clutch members decreasing when said shifting means shifts said guide means to the second position.
