    摘要: A thermal printer drive control apparatus of the type having a thermal print head comprising a plurality of heating elements provides for reliable cost effective thermal head temperature detection by means of producing multiple, different current flow intervals that are applied to binary data to produce data drive signals for the heating elements. The current flow intervals are based upon historical drive data derived from linear temperature conditions sensed at the thermal print head. This information is converted to a digitized representation for use in conjunction with a table placed in memory that provides predetermined current flow intervals based upon the digitized representation. Further, circuitry is provided to produce heating element drive signals having pulse widths based upon the determined current flow intervals.

    摘要: A paper cutter includes a blade extending in the width of a rolled paper, the blade having a linear edge and a serrated edge formed at an end of the linear edge. A paper guide for discharging the paper is disposed downstream from the cutter, the paper guide having an upper and a lower member and a discharge port at the downstream end thereof. A cutout section is formed at the upper member of the paper guide, and the position of the cutout section corresponds to the serrated blade edge in the width direction of the paper. The cutout section permits the paper to be grasped with fingers by the operator. When the paper is pulled, a force acts on the paper in a direction to press it against the serrated blade edge, cutting the paper from the edge.

    摘要: In an ink jet printer having pressure generate means for pressurizing ink inside the printer nozzles, either a first electric pulse of an amplitude enabling ink drop ejecting, or a second electric pulse of an amplitude lower than the amplitude of the first electric pulse for mobilizing ink inside a nozzle, is applied to each pressure generator synchronized to a reference signal of a single frequency. An ink drop is not ejected when a low amplitude second pulse is applied to a pressure generating means. Applying said second electric pulse instead stimulates ink around the nozzle so that high viscosity ink at the nozzle tip mixes with low viscosity ink deeper inside the nozzle, thereby lowering the overall viscosity of ink in the nozzle so that ink drop ejecting is easier.

    摘要: A technique is proposed for reducing leakage electromagnetic field that reduces the electromagnetic leakage from a connection point between a communication coupler and a signal transmission apparatus and that can conduct both communication and transmission of electric power. The signal transmission apparatus includes: a first sheet conductive body portion constituting a lower portion electrode; and a second sheet conductive body portion in a mesh shape which is laminated on the first sheet conductive body portion while a gap area is sandwiched therebetween and which includes an uneven mesh size area on which a sheet impedance is continuously changed.

    摘要: A wireless communication device (100) includes a first casing (10) and a second casing (20), and is switched between at least a first state and a second state by displacement of the first casing (10) and the second casing (20). The first casing (10) includes a first conductor (15) and a conductor element (36a) connected thereto. The second casing (20) includes a second conductor (25), and is connected to the first casing (10) so as to be rotationally displaceable with respect to each other around a perpendicular axis. In a first state, an opposite region (241) in the second conductor (25) and the conductor element (36a) are located at positions opposite to each other, and the conductor element (36a) and the second conductor (25) allow electrical conduction to each other at a predetermined frequency. In a second state, the electrical conduction state is different from that in the first state.
