Sheet package producing system, sheet handling device, and fillet folding device

A sheet handling device comprising:

• a support means for supporting plural sheets stacked on one another;
• a moving means for moving said support plate along a moving path;
• and
• an orientation changing means for adjusting an orientation of said support plate so that the support means is held at an inclined position relative to the moving path when said moving means moves said support means, to prevent said sheets from being offset by influence of inertia on said support means.

A sheet handling device comprising:

• at least one support plate for supporting plural sheets stacked on one another;
• a moving mechanism for moving said support plate along a moving path;
• an orientation changer for adjusting an orientation of said support plate, to prevent said sheets from being offset by influence of inertia on said support plate while said moving mechanism moves said support plate, and
• a control unit for controlling said moving mechanism, initially to move said support plate in acceleration in an accelerating step, next to move said support plate at a regular speed in an regular speed step, and then to move said support plate in deceleration in an decelerating step, wherein:
• said orientation changer includes a first rotating mechanism for rotating said support plate about a first axis extending in an extending direction in which said support plate extends from said moving mechanism;
• and
• said first rotating mechanism being controlled by said control unit, actuated in said accelerating step, for inclining said support plate to position an upstream edge higher with reference to said moving path, and actuated in said decelerating step, for inclining said support plate to position a downstream edge higher with reference to said moving path.
