The alignment plate 13 may function to move the print media such that the part, e.g., the sides of the print media to be stapled are disposed under the stapler 30.
The second tray 12 may be disposed in the first direction to be parallel to the first tray 11, and disposed under the first tray 11 so that the print media conveyed in the first direction are stacked on the first tray 11.
The conveyance apparatus 20 includes a driving motor 21 configured to generate a rotational force, a driving pulley 23 configured to receive the rotational force from the driving motor 21 through gears 22 to be rotated, a driven pulley 24 spaced apart from the driving pulley 23, a conveyance belt 25 hung on the driving pulley 23 and the driven pulley 24 to move around the driving pulley 23 and the driven pulley 24 according to rotation of the driving pulley 23, and a conveyance module 26 disposed at the conveyance belt 25 to be moved with the conveyance belt 25 and configured to convey the print media on the first tray 11 to the second tray 12.
According to an embodiment, the conveyance belt 25 includes a plurality, e.g., two conveyance belts 25 disposed in parallel and spaced apart from each other in a second direction such that the print media can be stably conveyed. The conveyance modules 26 may be installed at the two conveyance belts 25 at corresponding positions so that both sides of the print media on the first tray 11 simultaneously receive forces by the conveyance modules 26 to be conveyed.
According to an embodiment, the conveyance modules 26 may be disposed at the conveyance belts 25 to be spaced apart from each other in the longitudinal direction of the conveyance belts 25. The conveyance modules 26 disposed at the conveyance belts 25 alternately convey the print media on the first tray 11 to the second tray 12.
The main body 10 includes a support section 10a disposed at one side of the first tray 11 and configured to support, e.g., one end(s) of the print media stacked on the first tray 11. A through-hole 10b (see, for example, FIG. 4) may be formed in the support section 10a and through which the conveyance module 26 passes through the support section 10a in a first direction to enter the first tray 11, for example, from an upper side thereof. A slot 11a may be formed in the first tray 11 and through which the conveyance module 26 is able to move in the first direction while protruding over the first tray 11.
According to an embodiment, since the conveyance apparatus 20 includes the pair of conveyance belts 25 and the conveyance modules 26 are installed at the conveyance belts 25, through-holes 10b, e.g., two through holes and the slots 11a, e.g., two slots may be formed to correspond to the two conveyance belts 25.
As illustrated in FIG. 4, the conveyance module 26 includes a movable member 261 movably installed at the first tray 11 through the conveyance belt 25 in the first direction. A rotary member 262 may be rotatably installed at the movable member 261, and pass through the through-hole 10b according to movement of the conveyance belt 25 to move the first tray 11 in the first direction.
The movable member 261 may be configured to move with the conveyance belt 25 as one end thereof may be fixed to the conveyance belt 25 to move the conveyance belt 25. A first hinge section 261a, to which the rotary member 262 may be rotatably installed, may be provided at the other end of the movable member 261. A stopper section 261b configured to limit a rotational angle of the rotary member 262 may be provided, for example, at one side of the first hinge section 261a. 
A second hinge section 262a rotatably installed at the first hinge section 261a may be provided at one end of the rotary member 262. A protrusion 262b protruding in the first direction and configured to support the print media stacked on the first tray 11 may be formed at the other end of the rotary member 262. Accordingly, the rotary member 262 can rotate about the first hinge section 261a and the first hinge section 261a, which are rotatably installed, serving as a rotational center. The protrusion 262b of the rotary member 262 supports a side of the print media placed on the first tray 11 in a state in which the rotary member 262 is rotated.
The rotary member 262 may be rotated to support the print media on the first tray 11 while passing the through-hole 10b. The conveyance module 26 may be moved to move the print media in the first direction in a state in which the protrusion 262b of the rotary member 262 presses the print media.
A hooking member 263, for example, having a lower end extending to be disposed under a rotational center of the above-mentioned rotary member 262, may be provided at the rotary member 262 such that the rotary member 262 is rotated while passing the through-hole 10b. The main body 10 includes a hooking threshold member 14 protruding into the through-hole 10b to be hooked by the lower end of the hooking member 263. According to an embodiment, the hooking member 263 may be separately manufactured from the rotary member 262 and, for example, fixed to a side of the rotary member 262. The hooking threshold member 14 may be separately manufactured from the support section 10a and, for example, fixedly installed at the support section 10a. 
An exemplary operation of a print medium finishing apparatus according to an embodiment is described.
An exemplary print medium finishing apparatus receives the print media, on which image forming, for example, is finished, from the image forming apparatus P connected to the main body 10, and stacks the print media on the first tray 11.
When a set number of print media are stacked on the first tray 11, the two alignment plates 13 move to advance and retract in the second direction at both sides of the print media to align the print media stacked on the first tray 11.
When the alignment of the print media is terminated, the two alignment plates 13 move the print media to one side in the second direction such that the one sides of the print media to be stapled are disposed under the stapler 30. The stapler 30 is operated, for example, upward and downward, to staple, e.g., one sides of the print media after completion of movement of the print media.
After the stapling is terminated, a rotational force may be generated from the driving motor 21 to rotate the conveyance belt 25 around the driving pulley 23 and the driven pulley 24. As illustrated in FIG. 5, the conveyance module 26 may be moved in the first direction according to rotation of the conveyance belt 25 to pass through the through-hole 10b to protrude over the first tray 11.
During a process in which the conveyance module 26 passes through the through-hole 10b, an end, e.g., a lower end of the hooking member 263, provided at one side of the rotary member 262, may be hooked by the hooking threshold member 14 protruding into the through-hole 10b. Since the lower end of the hooking member 263 may be disposed under the rotational center of the rotary member 262, as illustrated in FIG. 6, the rotary member 262 may be hooked and rotated by the hooking member 263. As the rotary member 262 is rotated, the protrusion 262b of the rotary member 262 supports a side, e.g., the one sides of the print media stacked on the first tray 11.
The conveyance module 26 moves, e.g., continuously moves in the first direction, and the print media stacked on the first tray 11 are conveyed by the conveyance module 26 in the first direction to move to the second tray 12. Since the one sides of the print media are maintained while being supported by the protrusion 262b of the rotary member 262 even during a process of conveying the print media, disorder of alignment of the print media during the conveyance process is reduced.
According to an embodiment, while the hooking member 263 and the hooking threshold member 14 may be separately manufactured from the rotary member 262 and the support section 10a and then installed at the rotary member 262 and the support section 10a, respectively, an embodiment is not limited thereto. As illustrated in FIG. 7, a hooking member 2637 may be integrally formed, for example, with one side of the rotary member 262 during the process of manufacturing the rotary member 262. A hooking threshold member 147 may be integrally formed with the support section 10a during the process of forming the support section 10a. 
Although a few embodiments have been illustrated and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
