1. Field of the Invention
The present invention relates to a paper roll device, and more specifically, to a paper roll device capable of notifying an amount of the paper roll actively.
2. Description of the Prior Art
A conventional paper roll device, such as a lottery machine, a receipt machine or an ATM machine, often has a paper roll for sheathing a shaft as a paper feed mechanism. However, a detecting mechanism of detecting an amount of the paper roll is more complicated with the paper feed mechanism without the shaft. For example, in order to ensure whether the paper roll is run out, a cover of the conventional paper roll device is designed to be transparent, so that a user can see through the transparent cover to check the paper roll. In addition, an end portion of the paper roll can be marked, such as painting a red line, and the user knows that the paper roll is run out when the paper marked with the red line is conveyed out of the machine. That is, the conventional paper roll device cannot notify the user that the paper roll is run out early. Therefore, it is an important issue to design a paper roll device capable of notifying the user of the amount of the paper roll actively.

The paper roll device of the present invention is to dispose the lever capable of pivoting, and the paper roll contacts the end of the lever. The paper roll pushes the end of the lever gradually after consumption, so that the other end of the lever moves relatively. The detecting module disposed at the other end of the lever detects movement of the other end of the lever and sends the corresponding detecting signal to the control module. The control module determines whether the detecting signal corresponds to the alert value, so as to determine that the using state is the low amount state. Therefore, it solves the problems that the conventional paper roll device cannot actively notify the user that the paper roll is run out or is about to run out.
