Abstract: The soft-surfaced pressure roller is pressed vertically against a hard, heated roller - or vertically between two hard, heated rollers - when fixing is in progress. The present arrangement reduces this pressure while leaving the rollers in light contact and rotating at all other times. The driving gear of the lowest of the rollers is mounted on a pivoted frame on which it can drop down from the other rollers. It is raised when required on a pair of gear wheels mounted on a pivoted arm. When the pressure is required, an electrically operated clutch first holds the lowest of the auxiliary wheels on its axle - on which, till then, it had been free to turn. The drive on the raising wheel, which is in mesh with this lowest wheel, now turns the pivoted arm, raising the roller's driving gear on its pivoted frame.

Abstract: A sheet sorting device S in which sheets P are sorted with trays 41.....415 is being moved so that one of the trays, e.g. 44, corresponds to the sheet outlet 1,1 of an image forming apparatus C, is provided with a sheet conveying portion 14.....21 for causing sheets carried from the outlet 1,1 into the sheet sorting device S to be discharged out of the sheet sorting device S, thereby bypassing the device S and being passed into an adjacent sorting device S1 e.g. when the trays are full.

Abstract: A surface potentiometer has a conductive shield housing provided in proximity to a body to be measured, a cage-shaped chopper rotatable within the housing, and an electrode disposed further inwardly of the chopper. The chopper is rotated to induce in the electrode a voltage corresponding to the potential of the body to be measured, thereby measuring the surface potential of the body to be measured.

Abstract: PURPOSE:To improve the copying speed of an image forming device and to reduce the size by performing image formation through an electric system for the 1st time, switching a conveyance path and using a transfer material after transfer as an original, and forming an original image directly on a photosensitive body for the 2nd and succeeding times. CONSTITUTION:When an image processing part 42 receives an external electric signal, a rotary mirror 9 is positioned at a chained-line position under the control of a control part and the electric signal is converted into an exposure image by a laser scanner 43; and the image is formed on a drum type photosensitive body 2, transferred to the transfer material S, and fixed by a fixing part 22. The transfer material is guided to a flapper 33 positioned at a full-line position, and guided to the conveyance path 32 and conveyed to an original platen 3. When a detection sensor 31 detects the passing of the rear end of the transfer material, the flapper 33 is positioned at a broken-line position. Then, the rotary mirror 9 is positioned at a full-line position, the transfer material S mounted at a specific position is used as an original for the 2nd and succeeding copying processes to take copies not through the electric system E, and the transfer material S after transfer is discharged to a discharge tray 27.

Abstract: PURPOSE:To accommodate a sheet in reversed state into a tray from a discharge transport passage by installing a reversal transport passage between a pair of rollers and the discharge transport passage and installing a pair of transport rollers which can be revolved normally and reversely, in close to the reversal transport passage. CONSTITUTION:The captioned apparatus is constituted of guides 32 and 33 for receiving the sheet transported from a pair of rollers 23 and 25, reversal transport passage 35, two pairs of transport rollers 36 and 37 at the front and rear which are arranged close to the transport passage 35 and consist of two rollers 36a, 36b, and 37a, 37b which can be revolved normally and reversely, and a discharge transport passage 40 equipped with a pair of discharge rollers 39 consisting of two rollers 39a and 39b on the downstream side, and the normal and reverse revolution of the pair of transport rollers 36 and 37 are controlled by a sheet detecting sensor 41. Therefore, the sheet transported from the pair of folding rollers is introduced into the reversal transport passage 35 from the top edge side, and after the whole sheet is introduced, the sheet is transported into the discharge transport passage from the rear edge by the reversal of the pair of transport rollers 36 and 37, and the sheet is reversed.

Abstract: PURPOSE:To prevent the breakage and early abrasion by upwardly transferring the trunnion accommodated at the scooping-up position of a supporting frame in succession by the scooping-up projection of a transfer groove by the revolution of a transfer ring, thus permitting the certain transfer of the trunnion without using a spring. CONSTITUTION:When a copying paper sheet is loaded, the right and left transfer apparatuses 13 and 13' revolve at an equal speed on the basis of the detection of a paper-passing detecting switch, and a transfer ring 29 revolves in the direction A, and the trunnion 15a of a bin tray 3a on the uppermost stage at the position close to a slot 29a is scooped-up by a scooping-up projection 29b and engaged with the slot 29a, and the trunnion 15a is transferred upward along a guide groove 36 by the slot 29a, accompanied by the revolution of the transfer ring 29. When the trunnion 15a is transferred upeard, it contacts with the upper surface of a supporting frame 39, which is slid by the diameter portion of the trunnion, and also the lower trunnions 15b-15e are suspended onto the supporting frame 39, and the trunnion 15b of the bin tray 3b on the second stage is held in the vicinity of the transfer ring 29.
