Abstract
An imaging system includes a conveyor device to convey a sheet material along a conveyance path, a deformation tolerance portion located along the conveyance path, and a measurement device located in the deformation tolerance portion. The deformation tolerance portion includes a space to accommodate a bending of the conveyed sheet material. The measurement device measures a bending amount of the sheet material.
Claims15
An imaging system comprising:
- a conveyor device to convey a sheet material along a conveyance path;
- a deformation tolerance portion located along the conveyance path, wherein the deformation tolerance portion includes a space to accommodate a bending of the sheet material conveyed;
- and
- a measurement device located in the deformation tolerance portion, to measure a bending amount of the sheet material.

An imaging system comprising:
- a cassette to store a sheet material;
- a conveyor device to convey the sheet material along a conveyance path according to a conveying speed;
- a deformation tolerance portion located along the conveyance path to accommodate a bending of the sheet material in a direction that is angularly offset from the conveyance path;
- a first ultrasonic sensor located at an entrance of the deformation tolerance portion, to detect a leading edge of the sheet material at a detection timing;
- a second ultrasonic sensor located in the deformation tolerance portion, to measure a bending amount of the sheet material;
- an environmental sensor to measure a humidity inside the deformation tolerance portion;
- and
- a controller to determine a stiffness index of the sheet material based on the conveying speed of the conveyor device, the detection timing of the leading edge of the sheet material, the bending amount of the sheet material, and the humidity inside the deformation tolerance portion.
