  • Patent number: 10576760
    Abstract: A printer has a roll of a paper and a cutter. The cutter includes a stationary blade provided and a movable blade. The movable blade is movable in an up-down direction with respect to the stationary blade between a first position and a second position. The stationary-side cutting tooth is located at a position higher than a guide surface. The movable-side cutting tooth is located, with respect to the guide surface, at a lower position when the movable blade is located at the first position, at a higher position when located at the second position, and at a third position, which is between the first and second positions, when the roll is attached to an accommodating part of the printer. When located at the third position, at least a part of the movable-side cutting tooth is located at a higher position than the lower end of the guide surface.

  • Patent number: 9290024
    Abstract: The disclosure discloses a printer comprising a feeder, a printing head, a movable blade, a blade receiving member, a constant voltage circuit, a route switching device, and a switching control portion. The constant voltage circuit outputs a constant voltage to a secondary side based on a primary-side voltage supplied from a battery. The route switching device switches a current supply route from the battery to a motor to either one of a first route by which the constant voltage on the secondary side from the constant voltage circuit is supplied from the battery, and a second route by which the primary-side voltage is supplied without passing through the constant voltage circuit. The switching control portion controls the route switching device so that, triggered by non-detection of execution of the partial cutting, the current supply route is switched from the first route to the second route.
