  • Patent number: 8011844
    Abstract: A printer is disclosed. The printer includes a main body which contains a paper roll container where a paper roll is loaded, a lid for closing an opening section of the main body through which opening section the paper roll is loaded in the paper roll container, a letter printing mechanism which is formed when the lid is closed, and a detecting arm disposed on a rear surface of the lid for detecting a near-end state of the paper roll. When the paper roll is loaded in the paper roll container and the lid is closed, an arm main body of the detecting arm contacts an outer circumferential surface of the paper roll. When the paper roll reaches the near-end state, the detecting arm does not contact the outer circumferential surface of the paper roll and is moved, and a switch disposed at the main body becomes OFF.
