Title: Ribbon-feeding mechanism of color printer
Inventor: KAEDE YASUHIRO
IPC: B41J33/24
Filed: 1992-01-30
Abstract: PURPOSE:To shorten the period of time required for changing a printing color to promote the working efficiency of a color ribbon by computing the optimum feed rate of the color ribbon according to the width of a printing paper to be used and by controlling the rotational speed of a ribbon-feeding motor on the basis of the result of computation. CONSTITUTION:A controller 10 computes the optimum feed rate of a color ribbon by the use of an arithmetic unit 11 on the basis of the recognized width L3 of a printing paper P. The controller 10 feeds one pulse signal to a ribbon- feeding motor 6 whenever a pulse number fed from a motor-rotation detection sensor 9 reaches a computed pulse number, and the ribbon-feeding motor 6 rotates by one step at the time of receiving this pulse signal. Therefore, the rotational speed of the ribbon-feeding motor 6 is controlled by the periodic speed of the pulse signal fed from the controller 10. Thus, the color ribbon is used in the manner of avoiding waste, the length of the color ribbon for one color is smaller than the maximum print span of a printer, and the length of the ribbon wound at the time of changing a printing color shortens.

Filed: 1992-01-30
Abstract: PURPOSE:To obtain a height of a soldered part of an IC chip from a board and to improve reliability of its connection by providing a photoresist cured layer for controlling the height of the chip on the board. CONSTITUTION:A surface of the side formed with a land 5 of a board 4 is coated with photoresist 12, and a photomask is mounted at a predetermined position in close contact on the photoresist 12. The photoresist 12 is exposed through the photomask, thereby forming a cross-shaped cured layer 12a. Then, a solder bump 3 supplied to an electrode pad 2 of an IC chip 1 is aligned with the land 5 on the board 4, made to abut on the land 5, heated, and the bump 3 reflows. In this case, even if the chip 1 is sunk by its own weight, the height of the chip 1 on the board 4 at the time of mounting is controlled by the layer 12a of the photoresist 12 so that the solder is not laterally spread. Even when an interval of the lands 5 is narrow, generation of a bridge can be prevented.

Abstract: PURPOSE:To realize a gas-discharge type optical print head capable of forming a light source pattern with a high resolving power, by a method wherein, auxiliary discharge electrodes are disposed on one substrate provided with a cathode or an anode. CONSTITUTION:On the reverse side of a front substrate 16, a part of an anode 17 is extended outside the front substrate 16 so as to be at right angles to the longitudinal direction of a cathode 13. Both an auxiliary cathode 18 and an auxiliary anode 19 forming auxiliary discharge electrodes are disposed on the reverse side of the front substrate 16. While an auxiliary discharge is constantly carried out by using the auxiliary discharge electrodes 18, 19 provided on the front substrate 16 of one side, a voltage is applied between the desired cathode 13 and the anode 17. In this manner, the statistical lag at the start of discharge is inhibited, and a desired emission pattern can be obtained by generating a light-emission due to a gas discharge. Since the auxiliary discharge electrodes 18, 19 are formed only on the substrate 16 of one side, a substrate 12 of the other side can be provided only with the cathode 13 for a light source being closely arranged. In this manner, a gas-discharge type optical print head with a high-resolving power light source pattern can be realized.
