However, if the lead cam groove is tilted in the whole
range, the lead cam rotates under the influence of
weight of bin unit when the bin stops. So as to
prevent this rotation, the lead cam groove has the
horizontal part as shown in the figure below. When
the bin unit stops, the lead cam position sensor (PI20)
detects the position so that the roller is located on the
horizontal part.
The lead cam center position sensor (PI21) is
provided to detect the center position of horizontal
part of lead cam. It is used to synchronize with the
stapling operation and to ensure smooth stapling.
