Abstract: The present invention relates to an original document processing apparatus for conveying and delivering mounted original documents to a prescribed position that includes a conveyance section, an original document delivery section and a reverse-delivery section having a reverse path for looping and reversing the original document conveyed from the conveyance section to return the original document to the conveyance section, a first conveyance path route leading from the conveyance section through the reverse path to the conveyance section, a second conveyance path route branching at midway of the first conveyance path route to the original document delivery section, a third conveyance path route leading from the conveyance section to the original document delivery section. The reverse-delivery section has a first deflector for selectively introducing the original document conveyed from the conveyance section to the first conveyance path route and the third conveyance path route.

Abstract: The present invention relates to an original document processing apparatus for conveying and delivering mounted original documents to a prescribed position comprising a conveyance section, an original document delivery section and a reverse-deliver section having a reverse path looping and reversing the original document conveyed from the conveyance section to return the original document to the conveyance section, a first conveyance path route leading from the conveyance section through the reverse path to the conveyance section, a second conveyance path route branching at a midway of the first conveyance path route to the original document delivery section, a third conveyance path route leading from the conveyance section to the original document delivery section. The reverse-deliver section has first deflection means for selectively introducing the original document conveyed from the conveyance section to the first conveyance path route and the third conveyance path route.

Abstract: A belt supporting device includes a first support member for supporting a belt pulley, the member having a smaller width than that of the outer peripheral surface of the pulley, an endless belt wound on the pulley, a second support member for forming between the endless belt wound on the pulley and the second support member a space for extracting the endless belt in the axial direction of the pulley, and a positioning member located movably in and out of the space to maintain the space by entering the space and to thereby position the first and second support members.

Abstract: The present invention provides an automatic original supplying apparatus in which originals are stacked on an original tray as an original bundle and the originals in the original bundle are separated one by one from an uppermost one or from a lowermost one by a separation portion disposed at one side of the original tray. The apparatus comprises a guide passage for directing the original bundle to the separation portion, and a guide member provided at a tip end of the guide passage for upward and downward pivotal movement so that, when the originals are separated from the uppermost one, the guide member is rocked upwardly to protrude upwardly from the guide passage in an inclined fashion to thereby push a tip end of the original bundle to be directed to said separation portion, and, when the originals are separated from the lowermost one, the guide member is rocked downwardly to be retarded from the guide passage.

Abstract: The present invention provides a mold releasing elastic roller having an insulating elastic layer; an insulating and mold releasing surfacial layer formed on said elastic layer; and a primer layer for adhering the elastic layer and the mold releasing surfacial layer, the primer layer containing a material of low resistance.
