Abstract:
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.
Abstract:
A paper roll device includes a casing, two rollers, a lever, a resilient component, a detecting module and a control module. The two rollers are installed inside the casing and for supporting a paper roll cooperatively. An end of the lever is disposed between the two rollers, and the lever pivots around a shaft. The paper roll sinks to contact the end of the lever, so as to push the end of the lever in a first direction. The resilient component is connected to the lever and for supporting the lever in a second direction opposite to the first direction. The detecting module is for detecting a position state of the other end of the lever, so as to generate a corresponding detecting signal. The control module is electrically connected to the detecting module and for determining a using state of the paper roll according to the detecting signal.
