Abstract
Abstract An image forming apparatus which forms an opening larger in width than recording paper at the bottom of a casing in condition of normal use, the casing constituting a body housing therein main components, and which is provided with a guide means constituting part of a passing route of the recording paper in condition of normal use and constructed to be capable of projecting at one end from the opening at the bottom of the casing. Hence, in the apparatus, even when the recording paper jams in the casing, a user can take out the jammed paper therefrom without dividing the casing and inserting fingers of a user into the casing. Accordingly, the apparatus, which can adopt integral construction not dividable, is realizable of being small-sized lightweight, and inexpensive to produce, and of saving the manhour for assembly, improving reliability, and reducing the failure occurrence rate.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
218 words
An image forming apparatus provided in a casing having relative to the operating position of said apparatus, top, bottom, front, back, and right and left side surfaces, said apparatus comprising: a latent image holder; a developing means which develops latent images formed on said latent image holder so as to form toner images thereon; a transfer means for transferring said toner images formed on said latent image holder to a recording paper; a fixing means for fixing onto said recording paper said toner images transferred to said recording paper by said transfer means, so that a portion along the bottom of said casing is used as a passing route for said recording paper, characterized in that at the bottom of said casing an opening is formed having a larger length in the direction perpendicular to the passing direction of said recording paper than a width of said recording paper; a handle(s) mounted on the front of said casing, said casing being adapted to be capable of standing on its back side, for permitting access to said opening in the bottom of said case for removal of jammed paper; and guide means for said recording paper mounted within said casing above said opening, said guide means constituting a portion of said passing route and being rotatable toward said opening.
Claim 2
Dependent Claim
218 words
An image forming apparatus provided in a casing having relative to the operating position of said apparatus, top, bottom, front, back, and right and left side surfaces, said apparatus comprising: a latent image holder; a developing means which develops latent images formed on said latent image holder so as to form toner images thereon; a transfer means for transferring said toner images formed on said latent image holder to a recording paper; a fixing means for fixing onto said recording paper said toner images transferred to said recording paper by said transfer means, so that a portion along the bottom of said casing is used as a passing route for said recording paper, characterized in that at the bottom of said casing an opening is formed having a larger length in the direction perpendicular to the passing direction of said recording paper than a width of said recording paper; a handle(s) mounted on the front of said casing, said casing being adapted to be capable of standing on its back side, for permitting access to said opening in the bottom of said case for removal of jammed paper; and guide means for said recording paper mounted within said casing above said opening, said guide means constituting a portion of said passing route and being rotatable toward said opening.
