AI Technical Summary
Technical Problem
Media feeding devices face challenges in appropriately feeding multiple types of media due to issues such as jamming or double feeding caused by excessive pressure, and media slipping due to insufficient pressure.
Method used
A medium feeding device with a mounting table that can be raised or lowered, a pick roller, and a pressing member that applies pressure to the pick roller, adjusting the pressure based on the medium's speed and position to prevent jamming and slipping.
Benefits of technology
The device effectively feeds various types of media by dynamically adjusting the pressure on the pick roller, reducing jamming and slipping, and ensuring reliable media transport.

Abstract
To provide a medium feeding device, a medium feeding method, and a control program capable of appropriately feeding a plurality of types of media.SOLUTION: A medium feeding device includes: a pick roller that is disposed above a placement table, is provided so as to be capable of raising, and feeds a medium placed on the placement table; a pressure member that can apply a downward pressing force to the pick roller; and, when a tip of the medium does not reach a predetermined position within a predetermined time after the start of feeding the medium, or when a moving speed during feeding of the medium is equal to or lower than a predetermined speed, a control part that raises the placement table so as to press the medium placed on the placement table against the pick roller. The pressure member does not apply the pressing force to the pick roller when the pick roller is arranged at a first position, and applies the pressing force to the pick roller when the control part raises the placement table and the pick roller is arranged at a second position higher than the first position.SELECTED DRAWING: Figure 4
