Abstract:
A reading processing apparatus for a temperature display device includes: an obtaining device obtaining an image of the temperature display device; a storage storing color fading information for each temperature; and a temperature estimation device estimating an ambient temperature of the temperature display device. The obtaining device includes a time information image indicating time information and a temperature information image displaying information about a temperature and an elapsed time by a change in color, and to which image pickup time information is added. The color fading information indicates a relation between a color changed by a temperature change, an elapsed time, and a temperature. The temperature estimating unit estimates the temperature to which the temperature display device is exposed by checking color information and elapsed time detected from the image against the color fading information stored in the storage.
Abstract:
A pressure-sensitive adhesive label including: a support layer; a pressure-sensitive adhesive layer disposed on the support layer; a function layer disposed on the pressure-sensitive adhesive layer; and a release layer disposed on the function layer, wherein the function layer is configured to be opened by heating to expose the pressure-sensitive adhesive layer. In this manner, by providing the release layer as the uppermost layer, the pressure-sensitive adhesive label can be prevented from adhering onto the thermal head, that is, the sticking can be prevented, and hence the position and shape of the opening of the function layer can be accurately controlled.
Abstract:
A pressure-sensitive adhesive label includes: a base; the pressure-sensitive adhesive layer provided on the base; and a thermosensitive film provided on the pressure-sensitive adhesive layer. The base is made of one of paper and a polyolefin-based polymer. The thermosensitive film is opened by heating to expose the pressure-sensitive adhesive layer. The thermosensitive film is opened to form an opening with a diameter equal to or more than 40 μm. The pressure-sensitive adhesive layer has a thickness in a range of from 20 μm to 300 μm. The pressure-sensitive adhesive label has pressure-sensitive adhesive strength with respect to the adherend of 1 N/(50 mm width) to 20 N/(50 mm width).
