US 5,927,706 A · Automatic original supplying apparatus

Abstract

The present invention provides an automatic original supplying apparatus in which originals are stacked on an original tray as an original bundle and the originals in the original bundle are separated one by one from an uppermost one or from a lowermost one by a separation portion disposed at one side of the original tray. The apparatus comprises a guide passage for directing the original bundle to the separation portion, and a guide member provided at a tip end of the guide passage for upward and downward pivotal movement so that, when the originals are separated from the uppermost one, the guide member is rocked upwardly to protrude upwardly from the guide passage in an inclined fashion to thereby push a tip end of the original bundle to be directed to said separation portion, and, when the originals are separated from the lowermost one, the guide member is rocked downwardly to be retarded from the guide passage.

Dependent claims

An automatic original supplying apparatus in which originals are stacked on an original tray as an original bundle, and the originals in the original bundle are separated one by one from an uppermost one or from a lowermost one by a separation portion, which supplies the originals one by one by frictional operation of a rotary means selectively acting upon the originals from above or below and which is disposed at one side of said original tray, comprising:

a guide passage for directing the original bundle to said separation portion;
and
a guide member provided at a tip end of said guide passage for upward and downward pivotal movement so that, when the originals are separated from the uppermost one, said guide member is rocked upwardly to protrude upwardly from said guide passage in an inclined fashion to thereby guide a tip end of the original bundle to be directed to said separation portion, and when the originals are separated from the lowermost one, said guide member is rocked downwardly to be retracted from said guide passage.

An automatic original supplying apparatus in which an original bundle is stacked on an original tray to be separated one by one from an uppermost sheet or from a lowermost sheet by a separation portion including a pair of upper and lower rotary members and disposed at one side of said original tray,

characterized by
a guide member provided rockably in an up/down direction, said guide member, when separating the originals from the uppermost one, rocking upwardly to be sloped upwardly so that at least a part thereof protrudes from the lower rotary member thereby guiding up a tip end of the original bundle to be introduced to the separating portion;
and said guide member, when separating the originals from the lowermost one, rocking downwardly to be retracted from the lower rotary member.

An automatic original supplying apparatus in which an original bundle is stacked on an original tray to be separated one by one from an uppermost original or from a lowermost original at a separating portion including a pair of upper and lower rotary members disposed at one side of the original tray, characterized by,

guide means a sloped state of which is switched in response to switching of the original separation from an uppermost original or a lowermost original, said guide means forming a slope for guiding a tip end of the original bundle to the upper rotary member rotating for feeding the original when separating the originals from the uppermost one, and said guide means releasing the slope when the original separation is switched to the lowermost one.
