Fact 4: Hence, in tabbed paper insertion mode, in order to execute
continuous copying without generating paper jamming and
with good processing efficiency, when an ordinary paper or
tabbed paper are fed continuously respectively, it can be done
with the paper feeding interval Ta or paper feeding interval Tb
which corresponds with ordinary papers or tabbed papers, however,
when the papers are switched between the ordinary paper and
tabbed paper, it is necessary that the ordinary paper or tabbed
paper are fed by special Paper feeding interval Ta', Tb' different
from above described Ta, Tb. (Sugiyama: translation; p 32 l.17 to
p 33 l. 2)
From the disclosure of Sakamaki we make the following findings of fact:
Fact 1: The present invention relates to generally a device for detecting
the jamming of a copy material in a photocopying machine or the
like and more particularly a device for detecting the jamming of
copy material in a photocopying machine. (col. 1, ll.4-6)
Fact 2: One of the objects of the present invention is therefore to
provide a device for detecting the jamming of copy material
in a photocopying machine or the like capable of giving a warning
signal upon the occurrence of jamming in the whole path of the
copy material through the photocopying machine or the like by
detecting a difference between a reference time interval required
for the copy material to pass through the whole path and an actual
time interval required. (col.1, ll. 51-59)
Fact 3: The device for detecting the jamming of copy paper in a
photocopying machine in accordance with the present invention
is characterized by the fact that the difference between a reference
time interval counted by a timer 5 (See FIG. 2) which is actuated
in synchronism with the actuation of the switch 3 and an actual
time interval from the time when the switch 3 is actuated to the
time when the switch 4 is actuated is used to detect whether the
jamming of copy paper exists or not in the photocopying machine.
