Abstract:
1. A post-processing apparatus configured to be connectable to an image forming apparatus main body, including: a transport path along which a sheet-like image forming medium is transportable in a predetermined transport direction; a loading part which includes a loading face on which the image forming medium is loadable and on which a penetration part penetrating to an opposite face of the loading face is formed, and which constitutes a part of the transport path; a first folding member which is disposed at a side of the opposite face in the loading part; which is disposed so as to be movable between an initial position at which a tip thereof is located at a predetermined position of the side of the opposite face and a protrusion position at which the tip thereof is inserted into the penetration part and is located at a predetermined position of a side of the loading face; and which moves from the initial position to the protrusion position in a state in which the image forming medium is disposed on the loading part, thereby moving the image forming medium while bending the image forming medium; a second folding member which is disposed at the side of the loading face in the loading part, and which sandwiches and receives the first folding member along with the bent image forming medium in a state in which the first folding member is located at the protrusion position; a drive mechanism which reciprocates the first folding member between the initial position and the protrusion position, and which includes: a position detecting unit which detects that the first folding member is located at a first position between the initial position and the protrusion position and that the first folding member is located between the initial position and the protrusion position, which is located at a second position nearer the protrusion position than the first position; a time information output part that is allowed to output time information; a time monitoring part which measures a moving time that is a time from when the position detecting unit detects that the first folding member is located at the first position to when the position detecting unit detects that the first folding member is located at the second position based on the time information from the time information output part, and which determines whether the moving time has elapsed by a predetermined time; and a rotational driving control part which controls the rotary drive part so as to switch the rotational driving direction to a backward rotational direction when the time monitoring part determines that the moving time has elapsed by the predetermined time.
