摘要:
An adhesive label printer has a thermal activation device that thermally activates a thermally active adhesive layer of a thermally active adhesive sheet. The thermally active sheet has a recording surface formed on one side of a sheet-like base and the thermally active layer formed on the other side thereof. A recording device records information on the recording surface of the thermally active adhesive sheet. A platen roller conveys the thermally active adhesive sheet and has a roller portion made of least a fluorine atom containing rubber material.

A thermal activation device has a thermal head having heat generating elements for generating heat to heat a thermal activation sheet. A radiator absorbs and dissipates heat generated by the heat generating elements of the thermal head. The radiator has a portion disposed in contact with an introduction path along which the thermal activation sheet is introduced toward the thermal head for contacting the thermal activation sheet to preheat the thermal activation sheet as the thermal activation sheet advances in the introduction path.

A thermal activation method for a heat-sensitive adhesive sheet having a front end and a rear end. A heat-sensitive adhesive sheet is conveyed between a thermal head for generating heat and a platen roller by rotating the platen roller against the thermal head to thermally activate the heat-sensitive adhesive sheet. The thermal head is driven to cause the thermal head to generate heat in synchronization with conveyance of the heat-sensitive adhesive sheet by the platen roller so that the thermal head starts generating heat before the front end of the heat-sensitive adhesive sheet enters between the thermal head and the platen roller and while the platen roller rotates less than once between the point at which the thermal head starts generating heat and the point at which the front end of the heat-sensitive adhesive sheet enters between the thermal head and the platen roller.

In manufacturing method for a thermal head, concave portions, including a reference concave portion, are formed on a surface of a substrate so that a length of each of the concave portions other than the reference concave portion increases as a distance from the reference concave portion in a length direction increases and so that a width of each of the concave portions other than the reference concave portion increases as a distance from the reference concave portion in a width direction increases. A mark identifying the reference concave portion is formed on the surface of the substrate. An insulating film is thermally fusion bonded to the surface of the substrate including the concave portions formed thereon. Heating resistors are formed on the insulating film using a photo mask by aligning the photo mask with the substrate in accordance with the reference concave portion to form the heating resistors so as to be opposed to the plurality of concave portions.

A printer includes: a cutter unit for cutting a label sheet to obtain an adhesive label with a desired length by allowing the label sheet to pass through the cutter unit; an adhesive strength exhibiting unit for allowing the adhesive label to exhibit adhesive strength by heating the adhesive label; a sheet loosening unit placed on a downstream side of the cutter unit and an upstream side of the adhesive strength exhibiting unit in a sheet transporting direction; and a sheet-passage direction changing unit for changing the sheet-passage direction in the upstream sheet-passage part by changing a direction of the upstream sheet-passage part from a reference position at which a sheet-passage direction in the upstream sheet-passage part is placed on the same line as a sheet-passage direction in the downstream sheet-passage part to an inclined position at which the direction is inclined from the reference position.

A heating resistor element component has a substrate and an adhesive layer provided on the substrate and including an adhesive and gap members arranged substantially uniformly in the adhesive. A heat storage layer is laminated on the substrate through intermediation of the adhesive layer so that the gap members maintain a distance between surfaces of the substrate and the heat storage layer constant. At least one heating resistor formed on the heat storage layer has a heating portion that generates heat. A cavity is provided in a region of the adhesive layer and interposed between the surfaces of the substrate and the heat storage layer. The cavity functions as a heat insulating layer for regulating an inflow of heat from the heat storage layer to the substrate.

A heating resistance element component has a supporting substrate, an insulating film laminated on the supporting substrate, heating resistors arranged at intervals on the insulating film, a common wire connected to one end of each of the heating resistors, and individual wires each connected to another end of the each of the of heating resistors. A surface of the supporting substrate is formed with a first concave portion and a second concave portion. The first concave portion is arranged in a region opposed to heating portions of the heating resistors. The second concave portion is arranged at an interval in a vicinity of the first concave portion so that heat generated by the heating portions of the plurality of heating resistors is prevented from flowing into the supporting substrate.

A thermal head for expressing pressure-sensitive adhesive strength includes a heat-generating element on a principal plane of a substrate and heats a thermosensitive pressure-sensitive adhesive layer of a thermosensitive pressure-sensitive adhesive label. A thermally active component adhesion preventing layer that comes into sliding contact with the thermosensitive pressure-sensitive adhesive layer is formed on the principal plane of the substrate on an upstream side and a downstream side of the heat-generating element in a conveyance direction of the thermosensitive pressure-sensitive adhesive label, and a surface of the thermally active component adhesion preventing layer is formed along an outer circumferential surface of a second platen roller.
摘要:
Provided is an adhesive label that does not use release paper, is excellent in environmental resistance from the viewpoint of saving resources, is capable of controlling the position and area of an adhesive layer to be exposed with high precision so that adhesive strength is adjustable with ease depending upon the properties of an adherend. An adhesive label includes a support, an adhesive layer placed on the support, and a non-adhesive porous layer placed on the adhesive layer. The porous layer has a heat capacity smaller than that of the same material that is not porous, and hence, is opened with low heat energy, which is preferred for a portable label issuing device.
摘要:
A thermal head manufacturing method comprises a concave portion forming step of forming a concave portion on one surface of a supporting substrate, a bonding step of bonding a thin plate glass to the one surface of the supporting substrate where the concave portion has been formed in a manner that hermetically seals the concave portion and forms a hollow portion, a heating step of heating the supporting substrate and the thin plate glass which have been bonded together in the bonding step to thereby soften the thin plate glass and expand gas trapped inside the hollow portion, and a heating resistor forming step of forming a heating resistor on the thin plate glass so as to be opposed to the hollow portion. During the heating step, the thin glass plate undergoes plastic deformation, due to expansion of the gas inside the hollow portion, and rises toward an opposite side from the hollow portion, and a leveling step is carried out to level the outer surface of the plastically deformed thin glass plate.
