  • Patent number: 10663906
    Abstract: A printer includes a casing, a print mechanism disposed inside the casing, and a paper tray. A conveying route extends from the tray to the print mechanism, with a first roller disposed adjacent the tray to feed a sheet from the tray to the conveying route. A second roller is disposed in the conveying route and conveys the sheet fed by the first roller to the print mechanism. A driving source provides a driving source to the first roller and the second roller. A controller is configured to, in response to a printing request, apply the driving force from the driving source to the first and second rollers such that the first and second rollers rotate. In response to a magnitude of a load of the driving source, the controller applies the driving force to the second roller such that the second roller rotates, and the controller does not apply the driving source to the first roller such that the first roller does not rotate.
