摘要： PROBLEM TO BE SOLVED: To prevent decolorizing processing from being insufficiently executed with respect to a medium by detecting the temperature change of a power thermistor and judging the discontinuity of a lamp according to the detected result. SOLUTION: It is discriminated whether the temperature of a decolorizing processing part detected by a temperature sensor 44 is equal to or under the minimum value of processing optimum temperature or not when the supply of an AC power source to the halogen lamps 28 and 30 is ON-state. When it is under the minimum value, the decolorizing processing is executed while keeping up the ON-state of the lamps. Besides, it is judged whether the temperature of the decolorizing processing part arrives at the maximum value of the processing optimum temperature(Tmax) or not. When it becomes equal to or over Tmax, the ON/OFF control of the lamps is executed. By such control, the lamps are returned to be the normal ON-state when the temperature of the decolorizing processing part becomes the minimum value of the processing optimum temperature again. Thus, the discontinuity states of the power source lamps for decolorizing can be detected even when the decolorizing processing part is set under a high-temperature environment.

摘要： PROBLEM TO BE SOLVED: To provide a photoreactive and decolorable one-dimensional color toner for printing by an electrophotographic method capable of forming full- color images with high resolution. SOLUTION: This toner is a photoreactive one-dimensional color toner for printing by the electrophotographic method contg. >=3 kinds of dye component particles in which >=3 kinds of decolorable dyes and decoloring agents corresponding to the respective dyes are adjacently incorporated. The toner forms the full-color image by the decoloration of the decolorable dyes of the irradiated parts by irradiation with light of the wavelength of the absorption wavelength regions of the respective decoloring agents. Such toner is produced by polymerizing a mixture contg. the decolorable dyes, decoloring agents and thermoplastic resin formable monomers to respectively prepare the dye component particles, then kneading the respective dye component particles in combination in a thermoplastic resin which is the same as the thermoplastic resin described above or different therefrom and pulverizing the mixture.

摘要： PURPOSE: To simplify the structure of a device and also facilitate its operation by setting an operation tool under the condition of a coloring or discoloring effect state relative to the recording paper when the detection part detects projection light higher than the strength in a part. CONSTITUTION: A heat sensitive recording pen 2 as an operation tool is constituted of a heating body 20, a hollow light conduit 61 provided in the pen, a light incident hole 60 for letting light into the light conduit 61 from the outside, and a light receiving element 62 provided on the distal end of the light conduit 61. The light receiving element 62 passes through the light incident hole 60 and light conduit 61 and produces signal voltage according to the strength of incident light. The comparator circuit 64, when the output voltage value of the light receiving element 62 is beyond the voltage of the standard voltage generating circuit 63, generates control signals being transmitted to the input voltage to the output by a heat body control circuit 23, and when the output voltage value of the light receiving element 62 is below the voltage of the standard voltage producing circuit 63, it generates signals for interrupting the transmission of the input voltage to the output.

摘要： PURPOSE: To eliminate the adherence of dusts such as edge dusts, etc., and to improve the printing quality by providing a heat sink having a thermal head, and cleaning means disposed substantially in the same plane as the head. CONSTITUTION: A heat sink 18 is moved down toward a sheet at the time of printing, and a thermal head 22 is brought into contact with the sheet via a thermal ribbon. Any dot 22a is selectively energized while scanning a carrier 10, and the predetermined part of the ribbon is melted to print the sheet. Since cleaning means 26 is mounted at the sink 18, the means 26 rises and scans in synchronization with the head 22, and suitably cleans the sheet by a simple structure. The means 26 is mounted at the front position of the head 22 in the scanning direction, and head 22 passes after the means 26 cleans, and hence the possibility of the print failure is further reduced.
