Title: Paper feeder for printer
Inventor: ISHII HIDEKAZU
IPC: B41J15/16
Filed: 1984-01-31
Abstract: PURPOSE:To prevent jamming from occurring, by a method wherein a traction roller rotated at a circumferential velocity higher than that of a tractor mechanism is brought into elastic contact with a platen when feeding a sprocket paper by a forced-feed system, and is separated from the platen when feeding the paper by a traction system. CONSTITUTION:When feeding the sprocket paper 4 by the forced-feed system, a traction frame 13 is turned downward, and is fixed by a plate 14, while the traction roller 27 is brought into elastic contact with the platen 1 because a tension arm 29 is energized by a toggle spring 32. In this case, since the circumferential velocity of the roller 27 is higher than that of the tractor mechanism 2 and the frictional force of the roller 27 is smaller than that of a pinch roller 6, the paper 4 does not sag. On the other hand, in the traction system, the frame 13 is turned upward, while the arm 29 is moved leftward by the spring 32 to separate the roller 27 from the platen 1, thereby weakening the paper-feeding action of the platen 1, and the paper 4 is fed at an accurate pitch by the tractor mechanism 2 located at an upper position and rotated clockwise.

IPC: H05K9/00
Filed: 1992-01-31
Abstract: PURPOSE:To attenuate a leakage component of a 1st local oscillation output and to reduce an antenna leakage level by arranging a 1st local oscillation circuit and an RF input terminal so as to have a large spatial distance. CONSTITUTION:The location of arrangement of a 1st local oscillator circuit (1stOSC) 15 incorporated to an UP section 10 is set to a location surrounded by shield plates 32, 33 arranged in parallel with a slit 31 and a shield plate 34 arranged at a right angle to the slit 31. Since an input terminal 11 for an RF signal and the 1st OSC15 are arranged on a diagonal line remotest from the slit 31 in a 1st block (UP section 10) of a square tuner case, leakage of part of an output of the 1st OSC15 is reduced to the input terminal 11. That is, since the spatial distance between the 1st OSC15 and the RF input terminal 11 is large, the antenna leakage level is reduced.
