ロール紙の検出機構。[Claims for Utility Model Registration] A hopper 1 having a tray 2 for holding a roll paper 10, a lever 5 rotatably held by a support 4, and a sensor 8 for detecting the rotation of the lever 5. and one side 10A of the roll paper 10
and a detector 3 disposed in the roll paper 10.
A spring 9 engaged with one end of the lever 5 moves the protrusion 6 formed on the tip 5A of the lever 5 into the rolled paper so that the other side 10A of the lever 5 is pressed against the inner wall 2A of the tray 2. The roll paper is brought into pressure contact with the side surface 10A of the roll paper 10, and as the roll diameter D of the roll paper 10 decreases, the pressure contact of the protrusion 6 is removed from the side surface 10A, so that the lever 5 is rotated and the detection is performed by the sensor 8. A detection mechanism for roll paper, characterized in that the tip portion 5A is provided with a contact surface 7 that comes into pressure contact with the side surface 10A when the pressure contact of the protrusion 6 is removed from the side surface 10A. .
