An image forming apparatus having a front loading paper feeding member is described which has an improved jam removing mechanism. The apparatus includes a sheet holding section having sheet trays arranged in a vertical direction for holding copy sheets. A conveying section is included for conveying a sheet sent from one sheet tray of the sheet holding section to an image forming section. A connecting member is included in the conveying section to allow the sheet trays to be drawn out from the body of the image forming apparatus conjointly with the conveying section. Other connecting members may be included to connect the sheet trays together. Further, a door member including a sheet tray may be included in the apparatus.

Image forming apparatus having a front loading paper feeding member with

An image forming apparatus which facilitates the input and output of copy paper. One embodiment includes an image forming apparatus with paper supply trays, a development area, a console and a sorter. By pressing a transparent paper mode key on the console, normal and projector paper are sequentially fed from the trays to the development area and then to the sorter. The sorter is set in one of three modes by a sorter instructor. A manual key on the console allows an operator to set the instructor to position the sorter in any one of the three modes. The pressing of the transparent paper mode key or the detection by a detector of transparent paper in the feeding tray results in the instructor setting the sorter in a non-sort mode despite the sort instructor having been previously set in a different mode. Also, another embodiment of the invention includes a judging device for judging whether a cover copy mode or a page numbering mode has been inputted to the copying assembly and, if so, then the sorter instructor sets the sorter in a sort mode. Another embodiment uses a selecting device to match the detected size and orientation of the transparent paper with a similar detected size in one of a plurality of cassettes containing non-transparent paper. An additional embodiment features rear and face discharging modes which, when set, result in a predetermined positioning and sequencing of the transparent projector and normal paper.

Image forming apparatus having means for coordinating the input and

An image forming apparatus which has a contact glass, an original transporting part for transporting a sheet of original onto the contact glass, an optical exposure system for scanning the sheet of original placed on the contact glass by reciprocating movement below the contact glass, an image forming part for forming an image of the original obtained by the optical exposure system on a recording sheet, and a part for supplying the recording sheet to the image forming part. The original transporting part comprises an original storing part for storing sheets of original; means for transporting a sheet of original from the original storing part onto the contact glass; means for detecting the passage of the sheet of original, provided in the sheet transporting means; and means for outputting an original-exchange completion signal to the image forming apparatus after the passage detecting means detects the passage of the sheet of original and before the sheet transporting means positions the sheet of original onto a predetermined portion of said contact glass. The recording-sheet supply part comprises means for judging whether a next sheet of original to be transported to the contact glass exists; means for transporting a recording sheet to the image forming part; and means for controlling the transporting means whereby the recording sheet transporting means is begun before the optical exposure system starts to return, if a next sheet of original exists.

Transporting apparatus for sheets of original and recording-sheet

An apparatus for sorting and transferring sheets comprises storing means for storing a stack of sheets, first transferring means for transferring a sheet located at an end of the stack of the sheets from the storing means in a first direction, and second transferring means for transferring the next sheet located at the end of the stack of the sheets from the storing means in a second direction. The first and second directions are different from each other. The apparatus for sorting and transferring the sheets is applied; for example, to an automatic original transferring apparatus and a temporary storing tray of a copying machine.

Apparatus for sorting and transporting sheets

An electrostatic copying apparatus capable of both-surface copying includes a main copying system and a document sending device for conveying a document to be copied through an exposure area. The main copying system includes a copying paper conveying device defining a copying paper conveying passage, an image forming device for forming an image on copying paper conveyed through the paper conveying passage, a copying paper returning device defining a copying paper returning passage for returning copying paper having the image formed on one surface and a paper re-feed device for receiving the copying paper returned through the paper returning passage and feeding it again to the paper conveying passage. According to a first aspect, improvement is made in the paper re-feed device, and according to a second aspect, a document feed device in the document sending device is improved. There is also provided a sheet material feeding device which can be conveniently applied to the paper re-feed device or the document feed device. The sheet material feeding device includes a first feed device for feeding sheet materials in the stacked state from the uppermost one and a second feed device for feeding the sheet materials from the lowermost one.

Electrostatic copying apparatus capable of copying on both surfaces

An electrostatic copying apparatus which can form an image on both surfaces of a copying paper as required. The apparatus includes a copying paper conveying passage, a copying paper feeding means for feeding a copying paper sheet to the paper conveying passage, a conveyance controlling means disposed adjacent to the downstream end of the paper conveying passage, a copying paper discharging passage extending from its upstream end adjacent to the downstream end of the conveyance controlling means, a copying paper reversing passage extending from its upstream end adjacent to the downstream end of the conveyance controlling means, a copying paper returning passage extending from its upstream end adjacent to the upstream end of the conveyance controlling means, a copying paper re-feeding passage, and a copying paper re-sending means for re-sending a copying paper returned through the paper returning passage to the paper conveying passage through the paper re-feeding passage.
