A mechanism for reciprocating an original table of a copying apparatus, comprising a driving means for reciprocating the original table, and two clutch means for transmitting a driving force to said moving means, one of which is used when moving said original table forward and the other of which is used when moving said original table backward. The mechanism further comprises: one solenoid which is movably mounted; a change-over means for changing the position of the solenoid from a first position to a second position and vice versa in response to the movement of the original table; and a transfer means for actuating selected one of the clutch means in response to the operation of the solenoid, the selected one corresponding to the position of the solenoid.
