Abstract: A portable type image forming apparatus has a body with an upper and lower body members which are coupled by a hinge. A locking mechanism for locking the upper and lower members is provided at one side face of said upper body and lower body. At least one handle is provided for transporting the apparatus at the side face of the body opposite to the side face receiving the hinge. An auxiliary locking mechanism for locking the upper and lower members when the handle is held during transport is also provided.

Abstract: An image forming apparatus includes a detachable sub-assembly consisting of a latent image holder drum and cleaning means in a unitary assembly, whereby after the sub-assembly is removed from the image forming apparatus, the cleaning device and latent image holder drum can be individually separated from the sub-assembly. Also, a peel-off device is mounted on the sub-assembly for peeling recording paper away from the latent image holder drum.

Abstract: An electrophotographic copying machine includes a support plate for receiving originals of documents to be copied, the support plate being mounted for sliding laterally in reciprocation along the upper surface of the housing or body of the machine; a handle attached to a side or end of the housing farthest from the center of gravity of the machine for facilitating carrying of the machine, and lifting of the machine to stand on the opposite end or side; a pair of cushions mounted at opposite ends of the opposite side for protecting the body and the top of a sheet feed tray protruding therefrom when the machine is standing on the opposite side of and a lock member for restraining the original support plate from sliding out of the body when the machine is being transported or standing on the opposite end, whereby the lock member engages a power switch for preventing operation of the machine during restraining of the support plate.

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.

Abstract: A relatively small and lightweight electrophotographic apparatus includes a support plate for receiving originals, whereby the support plate reciprocates laterally between the front and back sides of the housing for the apparatus, wherein the center of gravity of the apparatus is biased away from the dimensional center of the housing or body toward the one of the front and back sides which the original support plate more greatly extends beyond and away from the body during reciprocation for scanning of originals, whereby even when heavy originals are placed on the original support plate, the apparatus does not tilt or incline away from its resting surface, even when the original support plate is in greatest extension beyond the body or housing. A handle, sheet feed cassette, and sheet feed tray are all mounted on or through one end of the housing to prevent the latter two from dropping out during transport, thereby facilitating transport.
