<P>PROBLEM TO BE SOLVED: To surely attach/detach a driving roller to/from a main body in a transmission apparatus for transmitting the rotation of a motor installed in the main body to the driving roller which is attached to the main body so as to be attached/detached to/from the main body in an axial direction. <P>SOLUTION: The transmission apparatus is provided with: an internal gear 28 fixed to the driving roller 4; a driving shaft 31 rotationally driven by the motor 22; a supporting member 29 fixed to the main body 1 so as to rotatably support the driving shaft 31; and an external gear 35 fixed to the driving shaft 31. When the driving roller 4 is loaded to the main body 1, the serration 37 of the internal gear 28 is engaged with the serration 36 of the external gear 35, then, the rotation of the motor 22 is transmitted to the driving roller 4. The supporting member 29 is formed to a cylindrical shape so as to cover the outer periphery of the external gear 35, and the supporting member 29 functions also as a guide for guiding the internal gear 28 so that the serration 37 of the internal gear 28 fixed to the driving roller 4 may be engaged with the serration 36 of the external gear 35 in the case of loading the driving roller 4 to the main body 1. <P>COPYRIGHT: (C)2007,JPO&INPIT |
