PROBLEM TO BE SOLVED: To provide a print mechanism capable of realizing heating and pressurizing at low cost and being miniaturized. SOLUTION: This print mechanism comprises a paper feeding mechanism (36) for relatively conveying a sheet medium (40) by a friction force to the face of the sheet medium (40), a low temperature thermal head (37) for partially heating the face of the sheet medium (40) at a low temperature, a pressurizing mechanism (70) for controlling a pressure to be partially applied to the face of the sheet medium (40), and an intermediate/high temperature thermal head (38) for partially heating the face of the sheet medium (40) at an intermediate or high temperature after applying the low temperature heat and the pressure thereto. The pressurizing mechanism (70) can control at least two grades of a high pressure condition and a low pressure condition with the pressure lower than that in the high pressure condition and is disposed between the low temperature thermal head and the intermediate/high temperature thermal head.
