Original handling apparatus

Claim 2

An original handling apparatus comprising: stacking means for stacking a bundle of originals; feeding means for separating the originals stacked on said stacking means one and for feeding the separated original; detecting means for detecting the thickness of the bundle of originals stacked on said stacking means; and control means for identifying over-stacking of the originals based on an output from said detecting means at the time when an operation of said feeding means is initiated, and for inhibiting the operation of said feeding means if the over-stacking of the originals is identifed.

Claim 3

An apparatus according to claim 1, wherein said feeding means further comprises circulating means for separating each original from the bundle or originals on said stacking means, feeding the separated original to an exposure position, removing the original from the exposure position after being exposed, and returning the exposed original onto said stacking means.

Claim 4

An apparatus according to claim 2, wherein said circulating means further comprises partitioning means, set on the bundle of originals stacked on said stacking means, for indicating one circulation of the originals.

Claim 5

An apparatus according to claim 3, wherein said detecting means is responsive to said partitioning means being placed on the bundle of originals, so as to detect if the bundle thickness is greater than a predetermined thickness.

Claim 6

An apparatus according to claim 4, wherein said detecting means detects a position of said partitioning means set on the bundle of originals.

Claim 7

An apparatus according to claim 5, wherein said control means inhibits operation of said feeding means when said detecting means detects that the position of said partitioning means exceeds a predetermined position.

Claim 8

An original handling apparatus comprising: stacking means for stacking a bundle of originals; carry means for separating and feeding each original from said stacking means to an exposing position, removing the original from the exposure after being exposing and returning the exposed original onto said stacking means; detecting means for detecting one circulation of the bundle of originals, said detecting means including partitioning means, set on the bundle of originals stacked on said stacking means and a sensor for sensing said partitioning means; drive means for driving said partitioning means for a predetermined period of time so as to set said partitioning means on the bundle of originals at the time when the operation of said carry means is initiated; and control means for inhibiting the operation of said carry means in the event that said sensor sensed said partitioning means a plurality of times during said predetermined period of time.

Claim 9

An original handling apparatus comprising: stacking means for stacking a bundle of originals; carry means for separating and feeding each original from said stacking means to an exposing position, removing the original from the exposure after being exposing and returning the exposed original onto said stacking means; detecting means for detecting one circulation of the bundle of originals, said detecting means including partitioning means, set on the bundle of originals stacked on said stacking means and a sensor for sensing said partitioning means; drive means for driving said partitioning means for a predetermined period of time so as to set said partitioning means on the bundle of originals at the time when the operation of said carry means is initiated; and control means for inhibiting the operation of said carry means in the event that said sensor sensed said partitioning means a plurality of times during said predetermined period of time.

Claim 10

An original handling apparatus comprising: stacking means for stacking a bundle of originals; carry means for separating and feeding each original from said stacking means to an exposure position, removing the original from the exposure position and returning the exposed original to said stacking means; detecting means for detecting one circulation of the bundle of originals; count means for counting each time an original is fed by said carry means from said stacking means; and control means, responsive to said count means and said detecting means, for controlling said carry means, wherein said control means stops the operation of said carry when the exceeds a predetermined number and said detecting means has not detected one circulation of the bundle of originals, and wherein the predetermined number corresponds to a maximum number of originals which can be stacked on said stacking means.

Claim 11

An original handling apparatus comprising: stacking means for stacking a bundle of originals; carry means for separating and feeding each original from said stacking means to an exposure position, removing the original from the exposure position and returning the exposed original to said stacking means; detecting means for detecting one circulation of the bundle of originals; count means for counting each time an original is fed by said carry means from said stacking means; and control means, responsive to said count means and said detecting means, for controlling said carry means, wherein said control means stops the operation of said carry when the exceeds a predetermined number and said detecting means has not detected one circulation of the bundle of originals, and wherein the predetermined number corresponds to a maximum number of originals which can be stacked on said stacking means.
