Heat-sensitive graph and text reduction instrument

The utility model relates to a thermosensitive graph-text reducing instrument which is characterized in that the inside of a machine box (1) is provided with an insulating binding post (11) which is wrapped with an electrothermal wire (12), one end of which is connected with one end of a temperature control switch (10), the other end of which is connected with one end of a power socket (7) by a connecting line (13). The other end of the electrothermal wire (12) is connected with the other end of the power socket (7). The control end of the temperature control switch (10) is connected with a temperature sensor (14) by a signal line (15). The temperature sensor (14) is arranged at the casing body of the machine box (1). In addition, a paper-fixing board (9) is arranged on an arched faceplate (2), and a paper-fixing slot (16) is arranged between the paper-fixing board (9) and the arched faceplate (2). The utility model can be applied to the reduction and reappearance after the depigmentation and disappearance of
