摘要： PROBLEM TO BE SOLVED: To eliminate transfer error of data by providing a paper discharge guide in a printer such that a printed sheet can be guided not to fall down to a communication path between a communication element and an information unit thereby preventing a printed sheet from intercepting an optical signal path. SOLUTION: When a transfer sheet 17, e.g. a thermal sheet is set on the outer circumferential part of a round platen 7 from a sheet inserting part 20 and printing is started, the transfer sheet 17 is loaded automatically and fed while being printed between a thermal line head 18 and the round platen 7. Subsequently, the transfer sheet 17 is passed above the round platen 7 while touching a sheet guide 19 and discharged under a state where the printing face is directing downward in front of a sheet insertion guide 23. The sheet guide 19 has a concave end part on the inlet part 19-2 side thereof so that the transfer sheet 17 can be guided smoothly. According to the arrangement, a printed sheet is prevented from being discharged to rear to a printer and intercepting the optical signal path of an infrared communication sensor 16.

摘要： PURPOSE:To prevent the forced rising and falling of the head part of a thermal transfer printer by setting the contact angle of a thermal head with a platen corresponding to the displacement between the center the width of an ink ribbon and printing center. CONSTITUTION:Since an ink ribbon 3 is forcedly allowed to fall when printing is applied only to the upper stage of an ink ribbon, the contact angle of a thermal head 3 and a platen 1 is set so as to be inclined by theta deg. in the forcedly rising direction of the ribbon 3. Since the ribbon 3 is forcedly allowed to rise when printing is applied only to the lower stage of the ink ribbon 3, the contact angle of the thermal head 3 and the platen 1 is set so as to be inclined by theta deg.in the forcedly falling direction of an ink ribbon 4. Concretely, the angle & of inclination is pref. set to theta-(1/4-10/4)DELTA1 when the displacement between the center of the width of the ink ribbon 4 and printing center is set to DELTA1mm. By this constitution, the forced rising and falling of the ink ribbon 4 at the part of the thermal head can be prevented.

摘要： PURPOSE:To facilitate the control of production and the pressing force of an oil coating quantity regulating blade. CONSTITUTION:A heat-resistant rubber plate 106b whose leading edge part 106c being a contact part with a heating roller 101 is convexly curved in a longitudinal direction is provided on a leaf spring 106a to constitute the oil coating quantity regulating blade 106, and the leading edge part 106c convexly curved of the rubber plate 106b is allowed to press-contact with the roller 101 by the elasticity of the leaf spring 106a, thereby the uniform contact state is obtained by comparatively weak pressing force and the accuracy of the oil coating quantity regulating blade is released and the pressing force is reduced. Since the leading edge part 106c is formed like a fine circular arc, the frictional resistance with the roller 101 is reduced, and the increase of the driving load of the roller 101 is reduced, even when the pressing force of the blade 106 is set high. The stable oil coating quantity is controlled, and a trouble such as the depletion of oil is prevented from occurring.
