Assignee: RICOH COMPANY, LTD.
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G

Claim 0:
1. A spectral-characteristic acquisition apparatus comprising:
a conveyor including
a first conveyance roller pair;
a second conveyance roller pair downstream from the first conveyance roller pair in a conveyance direction;

a sensor configured to detect that an object conveyed in the conveyance direction has reached the second conveyance roller pair;
a pressurizer configured to apply pressure to the object;
a color data obtainer configured to obtain color data from the object at a position where the object stops moving; and
circuitry configured to
cause the pressurizer to apply pressure to the object in response to the sensor detecting that the object has reached the second conveyance roller pair,
cause the second conveyance roller pair to drive with a driving force greater than a driving force of the first conveyance roller pair in response to the pressurizer applying pressure to the object, and

estimate a spectral characteristic of the object based on the color data obtained by the color data obtainer.
