Title: Paper sheet feeding mechanism for printer
Inventor: UCHIMURA KOJI
IPC: B65H27/00
Filed: 1985-08-10
Abstract: PURPOSE:To permit the feed of the continuous paper in the range from thin paper to thick paper by forming the step difference in the circumferential direction and at a part in the axial direction on the cuter periphery of a bail roller and intermittently releasing the excessive fed portion of a platen roll which is accumulated when the thin continuous paper is fed. CONSTITUTION:At least one stop difference 5a, 5a' larger than the thickness of thin paper is installed in the circumferential direction and a part in the axial direction of a bail roller 5, 5'. Then, though a thick paper sheet A2 is strongly pressed by the circumference of the bail roller 5, 5', in case of a thin paper sheet A1, slip is generated at the step difference part 5a, 5a' at least one time during revolution. The generation of excessive tension force is suppressed by releasing the accumulated excessively fed portion. Therefore, the feeding of continuous sheet of paper in a wide range from thin paper to thick paper is permitted by varying the position of the bail roller 5, 5'. Further, operation is facilitated, and the paper feeding faculty is not deteriorated with the simple constitution.

Title: Picture transmitter
Inventor: TAKEI MASAHIRO
IPC: H04N19/895
Filed: 1987-07-15
Abstract: PURPOSE:To prevent production of noise by stopping at least operations other than memory write for example during a period storing a video signal in a picture memory so as to eliminate the mixture of clock/beat in a frozen video signal. CONSTITUTION:When a CPU 12 commands the start of freeze of a video signal to a memory control circuit 46, the memory control circuit 46 gives a control signal changing an operation mode to stop all required clocks for the CPU to the CPU 12 via a line 61. When a reproduction mode switch 82 designates field reproduction, a luminance signal Y is stored in a memory M0 and only in the case of a color field transmission mode, line sequential color difference signal (R-Y)/(B-Y) is stored in a memory M1. With the monochroic frame transmission mode designated, only the luminance signal of one field is stored in the memory M0. Thus, no undesired beat signal is mixed to the video signal frozen in the picture memory.
