Paper roll device capable of detecting an open/closed state of a cover

摘要

The present invention discloses a paper roll device including a casing, a cover connected to the casing, a moving component, a first resilient component connected to the moving component, a lever pivoted to the moving component, a second resilient component, a detecting module and a control module. The first resilient component is for driving the moving component to move in a first direction. The lever pivots relative to the moving component as the moving component moves. The second resilient component is connected to a sensing portion of the lever and for supporting the lever in the first direction. The detecting module is for detecting a position state of the sensing portion of the lever, so as to generate a corresponding detecting signal. The control module is for determining an open/closed state of the cover relative to the casing according to the detecting signal.
