IPC: D02H13/00
Filed: 1988-06-13
Abstract: PURPOSE:To shorten a span of stopping time by installing a ratio control part in addition, keeping a ratio of each rotational frequency of a delivery motor and a winding motor at the time of stationary operation even during deceleration, and controlling either side to be followed up to the other. CONSTITUTION:When a relay contact Ry3 is closed and a decelerating command S3 is generated, a speed control part 10 controls a motor M1 for its deceleration in accordance with the specified sudden decelerating curve. On the other hand, a ratio control part 30 controls rotational frequency of a winding motor M2 subjected to a control system of a tension control part 20 to be followed up to that of a motor M1 subjected to a control system of the speed control part. At this time, each ratio of rotational frequencies of both these motors M1, M2 uses a ratio stored in stationary operation before the decelerating command S3 or rotational frequency stored in the stationary operation. Consequently, tension of a warp sheet S during decelerating action comes to a value approximate to the specified value during the stationary operation. Moreover, it is follow-up control by a speed control system excellent in quick-responsiveness, sudden deceleration can be done.

Title: Developing device
Inventor: HINO TAKU
IPC: G03G15/08
Filed: 1982-08-23
Abstract: PURPOSE:To prevent malfunction due to uneven distribution of toner, by providing a detecting member for the remaining amount of a developer which is made of a conductor to a side wall of a developer supplying means which contains the developer together with a developer carrier applied with an alternating bias voltage. CONSTITUTION:A conductor 9 arranged extending in the axial direction of a sleeve 1 along the side wall in a hopper 6 is coated with an insulating material 10. This conductor 9 has shielding effect which prevents the evial influence of the alternating bias voltage applied to the sleeve 1 from leaking out of the hopper 6. The conductor 9 induces a potential difference corresponding to the AC potential applied to the sleeve 1. This potential difference varies with the amount of toner T between the sleeve 1 and conductor 9. For this purpose, this output potential difference is led from a contact 11 to a detecting circuit for the remaining amount of toner, thereby detecting how much the toner is left.

Abstract: PURPOSE:To automatically correct the alignment of an edge of a sheet of recording paper so that the edge becomes parallel to the printing direction even when the paper is diagonally inserted, by a method wherein independent paper transfer devices, one for transferring the recording paper in the vertical direction and the other in the horizontal direction, are provided, and two or more rollers for transferring the recording paper in the line-direction are independently rotated. CONSTITUTION:A paper feed mechanism has line-direction paper feed rollers 2a and 2b and column-direction paper feed rollers 4, and paper detecting photo sensors 3a and 3b are attached parallel to a printer main body. When a sheet of recording paper 7 is diagonally inserted, there is a time lag between the time at which the photo sensors 3a, for example, first detects the edge of the recording paper 7 and the time at which the paper detecting sensor 3b detects it. At this time, the line-direction paper feed roller 2a located on the side of the paper detecting sensor 3a which first detects the edge of the recording paper 7 is stopped immediately after the paper detecting sensor 3a detects the edge of the recording paper 7. The line-direction paper feed roller 2b located on the opposite side is continuously rotated until the paper detecting sensor 3b detects the edge of the recording paper 7, and then stopped. In the case the paper detecting sensor 3b first detects the edge of the recording paper 7, the paper feed amount is adjusted in the same manner. When the correction is not complete at a time, the recording paper 7 may be repeatedly transferred up and down two or more times so that the correction is performed properly.
