Abstract
In the copying apparatus, recording paper with an image on one side thereof formed in an image forming section is inserted into an auto document unit. In the auto document unit the recording paper is inverted upside down, while intervals of a plurality of sheets of recording paper are adjusted at predetermined positions, on an inverting path bent to form upper and lower stages.
Claims23
A copying apparatus having an image forming section that forms an image on recording paper and an auto document unit that inverts upside down the recording paper with the image formed thereon to return to said image forming section, said auto document unit comprising:
- an inverting path which takes in the recording paper with the image on one side thereof from said image forming section, and which inverts the recording paper upside down by a path bent to form upper and lower stages;
- a plurality of rollers that feeds the recording paper while adjusts intervals between a plurality of sheets of the recording paper at predetermined positions on said inverting path;
- a lower cover that covers a part of a lower path of said inverting path;
- and
- an upper cover having a first cover that covers an upper path of said inverting path and a second cover that covers an other area of said lower path of said inverting path except the part that said lower cover covers, said first cover and said second cover being integrated into said upper cover.
A copying apparatus having an image forming section that forms an image on recording paper and an auto document unit that inverts upside down the recording paper with the image formed thereon to return to said image forming section, said auto document unit comprising:
- an inverting path which takes in the recording paper with the image on one side thereof from said image forming section, and which inverts the recording paper upside down by a path bent to form upper and lower stages;
- a plurality of rollers that feeds the recording paper while adjusts intervals between a plurality of sheets of the recording paper at predetermined positions on said inverting path;
- an upper cover having a first cover that covers an upper path of said inverting path and a second cover that covers a part of a lower path of said inverting path, said first cover and said second cover being integrated into said upper cover;
- and
- a lower cover which is attached to said upper cover to be opened or closed with respect to said upper cover, and which covers an other area of said lower path of said inverting path except the part that said second cover covers,
- wherein said lower cover is opened from said upper cover by a weight thereof when said upper cover is opened.
A copying apparatus having an image forming section that forms an image on recording paper and an auto document unit that inverts upside down the recording paper with the image formed thereon to return to said image forming section, said auto document unit comprising:
- an inverting path which takes in the recording paper with the image on one side thereof formed in said image forming section, and which inverts the recording paper upside down by a path bent to form upper and lower stages;
- a plurality of feeding rollers that feeds the recording paper while adjusts intervals between a plurality of sheets of the recording paper at predetermined positions on said inverting path;
- a discharging roller that discharges the recording paper from said inverting path;
- and
- an incline correcting guide that corrects an incline of the recording paper before said discharging roller discharges the recording paper.
A copying apparatus having an image forming section that forms an image on recording paper and an auto document unit that inverts upside down the recording paper with the image formed thereon to return to said image forming section, said auto document unit comprising:
- an inverting path which takes in the recording paper with the image on one side thereof formed in said image forming section, and which inverts the recording paper upside down by a path bent to form upper and lower stages;
- a plurality of feeding rollers that feeds the recording paper while adjusts intervals between a plurality of sheets of the recording paper at predetermined positions on said inverting path;
- a lower cover that covers a part of a lower path of said inverting path;
- an upper cover having a first cover that covers an upper path of said inverting path and a second cover that covers an other area of said lower path of said inverting path except the part that said lower cover covers, said first cover and said second cover being integrated into said upper cover;
- a discharging roller that discharges the recording paper from said inverting path;
- and
- an incline correcting guide that corrects an incline of the recording paper before said discharging roller discharges the recording paper,
- wherein said second cover of said upper cover forms a part of an upper surface of said lower path of said inverting path, while forms an area corresponding to said incline correcting guide, and has on its surface faced to the recording paper a form of waves along a direction for feeding the recording paper.
A copying apparatus having an image forming section that forms an image on recording paper and an auto document unit that inverts upside down the recording paper with the image formed thereon to return to said image forming section, said auto document unit comprising:
- an inverting path which takes in the recording paper with the image on one side thereof from said image forming section, and which inverts the recording paper upside down by a path bent to form upper and lower stages;
- a plurality of feeding rollers that feeds the recording paper while adjusting intervals between a plurality of sheets of the recording paper at predetermined positions on said inverting path;
