  • Publication number: 20160264281
    Abstract: Provided is a label feeding device that is capable of efficiently peeling and feeding liner-less labels one by one, said liner-less labels comprising multiple labels that are arranged, without using release paper, such that each label is bonded to the surface of a label thereunder at an overlapping section while being displaced from the lower label at a displaced section. The labels are moved by means of a conveyor (8) that has on a surface thereof protrusions or grooves to which the labels are temporarily attached, and the conveyor bends at a peeling part (9), thereby peeling off the displaced section (5) of the upper label from the conveyer. A slider (13) that presses the lower label against the conveyor surface is movably disposed at the peeling part, thereby preventing the lower label from being peeled off from the conveyor. The displaced section projecting from the conveyor is pinched by a claw mechanism (12) and carried to a label ejection slot (11).

  • Patent number: 9112468
    Abstract: An audio device prevents an excessive volume output in a case such as when a set of headphones is replaced or a power supply is turned ON from OFF. A mute control circuit includes a switch that detects insertion of a headphone plug and a switch that detects a volume position. When no insertion of a headphone plug is detected, a mute mode is activated to output no audio signals. When insertion of a headphone plug is detected and it is not detected that the volume position is set at a mute position or near to the mute position, the mute mode is maintained, while when it is detected that the volume position is set at the mute position or near to the mute position, the mute mode is canceled.
