Title: Thermal recorder
Inventor: FUKUI HIROSHI
IPC: B41J2/36
Filed: 1985-04-01
Abstract: PURPOSE:To enable uniform recording, by a method wherein driving voltage for a heating element group on the forward side with respect to a recording direction is set to be different from that for a heating element group on the backward side. CONSTITUTION:For example, in the case of printing 'C', when a group of heating elements DA1-DA8 for exclusive use in odd-numbered cycle are brought onto a line 51, a voltage of VAA is impressed on the elements DA2-DA6 to generate heat, thereby printing. Next, when the recording head 11 is moved rightward so that the elements DA1-DA8 are located on a line 54 while heating elements DB1-DA8 are located on a line 52, a voltage VBB is impressed on the elements DB1-DB7 for exclusive use in even-numbered cycle, thereby performing printing. In this case, the voltage VBB is determined in consideration of the residual heat in a heat-fusible ink ribbon warmed when the driving voltage VAA is impressed on the elements on the forward side. Then, an odd- numbered cycle is carried out to record as indicated by a line 55, and then even-numbered dots are recorded as indicated by a line 54. Accordingly, 'C' is completely printed.

IPC: B41J2/44
Filed: 1993-03-25
Abstract: PURPOSE:To extend the life of a light emitting diode by differentiating the gap positions between the printed circuit boards provided in the vicinity of one and other long sides of a base stand in the longitudinal direction of the base stand and setting the gaps in an obliquely crossing or stepped state in the longitudinal direction. CONSTITUTION:The position of the gaps 26 between light emitting diodes 16 provided at the position corresponding to the gap 12 of printed circuit boards 5a, 5b and the position of the gap 27 between the light emitting diodes 16 provided at the position corresponding to the gap 9 between printed circuit boards 4a, 4b are made different. When the temp. of this optical printing head rises, the optical printing head is bent in an upwardly protruding state at the part of the gap 26 by the difference in the coefficient of thermal expansion between a base stand 1 and the circuit board 5a but, since the gap 12 is shifted from the gap 9 of the circuit board 4a in the gap 26, there is no effect of heat strain due to the circuit board 4a. Therefore, the heat strain of the light emitting diodes 16 adjacent to the gap 26 is reduced by half as compared with conventional one and the mutual damage of the light emitting diodes 16 due to heat strain is not generated.
