JPS54147842A - Recording paper conveyor of electrostatic recorder - Google Patents

Abstract

PURPOSE: To employ top developing system and reduce occupying area by forming an upward recording paper inverting guide bent path between a cutter and developing and fixing devices, providing recording paper conveying means in the bent path and forming the lower part of the bent path as the open part for recording paper buffer.

CONSTITUTION: Electrostatic recording paper 1 is formed of electrostatic latent images on its bottom face by a multistylus recorder 2 which is pulled by feed rollers 5 and synchronizes to the rollers 5. Following to this, the recording paper 1 goes through a cutter 6 and is led to a stationary paper guide 8 and a movable paper guide 7, where it is inverted to have its latent image face faced upward, thence the paper enters a developing device 11. Here, the latent images on the recording paper 1 are turned to sensible images by toner and the unfixed toner is fixed by the next fixing device 12, after which the paper is discharged onto a copy tray 13. The movable paper guide 7 is mounted to the lower edge of the outside circumference of the inversion bent path of the recording paper 1 movably to an axis 71 together with the stationary paper guide 8. When the leading end of the recording paper reaches the inlet rollers 9 of the developing part, the signal of a sensor 10 causes the rollers 9 to stop. As a solenoid 14 is energized, the rollers trun to open the lower part of the bent path.
