Abstract
Abstract An electronic copying machine of the shell-type with a main body having an upper unit and a lower unit. The upper unit is provided with an original tray on which originals to be copied after being automatically fed to an exposure table are disposed. The upper unit is connected to the lower unit by a connecting part, in such a way that the upper unit can be swung by a predetermined angle in relation to the lower unit. The original tray is slanted, with its front end being made lower than its back end, to thereby form an elevation angle equal to or larger than the predetermined angle, in relation to the horizontal face. Even if the upper unit is swung by the predetermined angle, in relation to the lower unit, to expose the inside of the copying machine when a paper jamming trouble occurs the original tray is not slanted until its back end is made lower than the horizontal face, thus preventing the originals from sliding down from the back end of said original tray.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
129 words
An image forming apparatus, comprising: a main body having a first unit and a second unit which are separable from each other; connecting means for connecting the first and second units to each other in such a way that the first unit is swingable by a predetermined angle in relation to the second unit; and disposing means having a disposing face on which sheets to be fed to the first unit are disposed, attached to the first unit, and said disposing face is slanted by an elevation angle equal to or larger than said predetermined angle, and in a direction which is the reverse of that in which the first unit is swung in relation to the second unit, when the first unit is closed to the second unit.
Claim 2
Dependent Claim
129 words
An image forming apparatus, comprising: a main body having a first unit and a second unit which are separable from each other; connecting means for connecting the first and second units to each other in such a way that the first unit is swingable by a predetermined angle in relation to the second unit; and disposing means having a disposing face on which sheets to be fed to the first unit are disposed, attached to the first unit, and said disposing face is slanted by an elevation angle equal to or larger than said predetermined angle, and in a direction which is the reverse of that in which the first unit is swung in relation to the second unit, when the first unit is closed to the second unit.
Claim 3
Dependent Claim
34 words
An image forming apparatus according to claim 1, wherein said connecting means includes a shaft provided to the first unit, and a supporting part provided to the second unit to rotatably support the shaft.
Claim 4
Dependent Claim
43 words
An image forming apparatus according to claim 2, wherein said connecting means includes a stopper section which is brought into contact with the second unit to define the predetermined angle by which the first unit is swung in relation to the second unit.
Claim 5
Dependent Claim
49 words
An image forming apparatus according to claim 1, wherein between said first and second units a passage for feeding sheets of paper is formed and can be easily exposed by swinging the first unit in relation to the second unit when a paper jamming trouble is to be solved.
Claim 6
Dependent Claim
76 words
An image forming apparatus according to claim 1, wherein said first unit includes a handle which serves to lock the first unit to the second unit when the first unit is seated on the second unit; whereby, when the handle is lifted to unlock the first unit from the second unit, the first unit can be swung in relation to the second unit, to form the predetermined angle between the first unit and the second unit.
Claim 7
Dependent Claim
51 words
An image forming apparatus according to claim 1, wherein said disposing means includes an original tray on which originals are disposed, the first unit includes an exposure table where the originals are exposed, and an originals-feeding device for automatically feeding the originals stacked on the original tray toward the exposure table.
Claim 8
Dependent Claim
29 words
An image forming apparatus according to claim 6, wherein said original tray includes guide plates for guiding the orignals in the originals feeding direction, erected from both sides thereof.
Claim 9
Dependent Claim
40 words
An image forming apparatus according to claim 1, wherein said main body includes a cover for covering the first and second units as a single unit, and wherein said cover can be uncovered to expose the first and second units.
