徴とするロール紙のニアエンド検出機構。In a near-end detection mechanism that detects the near-end of a roll paper using a state detection mechanism using a Hall element, - the roll paper 1 contacts a part of the outer periphery of the roll paper and follows changes in the outer diameter of the roll paper; This roll paper pressing means applies a predetermined pressure, and is connected to the roll paper pressing means via a toggle mechanism, so that the roll paper pressing means rotates following the change in the diameter of the roll paper, and the rolled paper a near-end detection lever configured to move around the outer periphery and be repelled and reversed by a toggle mechanism when the outer diameter of the roll paper reaches a predetermined diameter; a tip of the near-end detection lever is moved and the toggle mechanism is configured; 1. A near-end detection mechanism for roll paper, comprising a near-end detection Hall element that is actuated by an applied magnetic field and detects a near-end when reversed.
