2-6. Folding Plates
As the folding plate mechanism is more or less the same as the DF-520N, only important differences are described in
this section.
Overall view of folding plate mechanism
(1) Movement control of folding stopper
A slit plate (index plate) divided into 12 parts (pulses) is mounted to a screw shaft with a pitch of 1.5 mm (0.06").
The number of slits (pulses) is counted by two photointerrupters (index sensor) to control the moving distance
and direction of the folding stopper.
The minimum distance moved by the stopper is 0.125 mm (0.005") of one pulse of the above index plate.
The restricted value of each folding plate is shown below.
Limitations of length of folded plane
