Information processing apparatus and its control method
First Claim
1. An information processing apparatus, which simulates a behavior of a sheet-like printing medium having a flexibility when the printing medium is conveyed in a conveying path including a convey roller pair, comprising:
- setting means for setting a condition including an information associated with a rigidity of the convey roller pair that consist of a first roller and a second roller arranged in the conveying path;
contact area shape formation means for forming a shape along a surface shape of the first roller having a higher rigidity than the second roller as a shape of a contact area where the first roller and a second roller contact each other when a rigidity ratio of the first roller to the second roller based on the condition set by said setting means is not less than a predetermined value; and
simulation means for simulating the behavior of the printing medium when the printing medium is conveyed in the conveying path on the basis of the shape of the contact area.

Abstract
When the convey behavior of a flexible medium conveyed in a conveying path is analyzed by simulation, a design support apparatus of this invention executes 1) processing for approximating a nip on a model to an actual nip, 2) processing for matching a feature point of a drive chart with a calculation step upon making a numerical calculation for solving a motion of a flexible medium using the drive chart, and 3) processing for reflecting velocity variations due to deformation of a convey roller pair, thus implementing a simulation with high accuracy. When the design support apparatus of this invention is used, even a designer who does not have expert knowledge on simulation can analyze the convey behavior of the flexible medium conveyed in the conveying path with relatively higher accuracy.
