  • Publication number: 20240066898
    Abstract: A printing device 1 includes a print section 8 for printing on a continuous medium M, a pair of holding sections 3 each having an insertion section 15 configured to be inserted into one of a first winding core of the wound medium M or a second winding core for winding the medium M from an outer side in an extending direction of the winding core, and a support section 19 for supporting the holding section 3, wherein the support section 19 is disposed closer to the print section 8 than the holding section 3 in a first direction, which is a direction from the holding section 3 toward the support section 19, of directions perpendicular to the extending direction of the winding core. By adopting the printing device 1 having such a configuration, it is possible to configure the printing device 1 to be lowered.

  • Patent number: 9446609
    Abstract: A cutter device includes a cutter configured to cut a material to be cut; a carriage having a cutter and moving in a widthwise direction with respect to a feeding direction of the material to be cut; and a guide unit configured to guide the carriage in the widthwise direction and, assuming that the movement of the carriage when the cutter cuts the material to be cut is an outward route, a homeward route of the cutter of the carriage is different from the outward route of the cutter, and is shifted from the outward route toward one material to be cut which moves first in the direction away from the other material to be cut in the feeding direction immediately after the cutting from between the materials to be cut divided into two parts.

  • Patent number: 9302510
    Abstract: A medium loading device includes a support unit having shaft members mounted on both end portions of a roll paper and flange member and a loading portion where the roll paper with the support unit is loaded. The loading portion includes a rotary driving portion as a driving source to rotate the roll paper, a rotation shaft to transmit torque of the rotary driving portion to the roll paper via the shaft member, and an operation portion that moves the rotation shaft between a transmission position to transmit the torque to the roll paper and a non-transmission position not to transmit the torque to the roll paper. In an axial direction of the roll paper when the roll paper is loaded into the loading portion, the operation portion is disposed between the position where the shaft member is located when the roll paper is loaded and the rotary driving portion.
