Stapler movement control

A. Stapler movement operation
• Since the stapler /Fr [11] and the stapler /Rr [1] operate symmetrically, the explanation is
given of the stapler /Rr [1].
• The stapler movement motor [9] moves the stapler.
• When the stapler movement motor rotates as shown in [10], it drives the stapler drive
rack /Rr [8] backward with the stapler via the pinion gear [12].
• The stapler spring /Rr [6] always applies a rotational force to [7] on the stapler. However,
the stapler does not rotate because the height of the stapler guide roller [3] is restricted
to the same height as the stapler rotational shaft by the rack mounting platform [4].
• When the stapler moves backward, the guide roller is pressed into the flute [5] on the
rack mounting platform and the stapler rotates as much as the difference to the stapler
rotation shaft /Rr [2] so that the stapler moves to the one-corner stapling position.

B. Stapler movement control
(1) Size movement in 1 staple
• Transmitting the FNS signal from the main body, the stapler movement motor turns ON to
widen the distance between the staplers. It stops when they are positioned at the speci-
fied positions.
(2) 2 staples
• The staplers do not move because the stapling operation is performed at the home posi-
tion.
