  • Publication number: 20140239113
    Abstract: There are provided a roll sheet conveying apparatus and a sheet conveying control method wherein it is possible to control motor driving for conveying a roll sheet at appropriate timing to keep constant the tension of the sheet to be conveyed without performing a special identifying operation. For this feature, a relationship between friction load torque on the roll sheet and the mass of the roll sheet is previously stored in a storing unit, whereby the moment of inertia of the roll sheet can be detected at appropriate timing during printing. As a result, the optimum tension of the sheet to be conveyed can be maintained by appropriately adjusting the driving control of a sheet feeding motor and a conveying motor without performing a special identifying operation.

  • Publication number: 20120263514
    Abstract: This invention has been made to cause a printing apparatus for conveying roll paper and performing printing to simultaneously attain a stable conveyance accuracy and prevent skewed conveyance independently of LF roller driving conditions and disturbance conditions that variously change as the roll paper state changes. For this purpose, a feed motor is used as a load generator for the roll paper. A section from a conveyance operation by the LF roller to the next conveyance operation is divided into a plurality of sub-sections. A feed mechanism is controlled by switching between a feeder load generation section and a feeder load zero section for each sub-section.
