摘要:
A paper arranging device includes a driving roller and an idle roller disposed adjacent to each other to form a nip, a first sensor to sense a location of moving paper, and a lever having a first end which extends to a perimeter of the nip to block a tip of the paper moving toward the nip and the other end which extends to a perimeter of the sensor, the lever being rotatable with respect to a predetermined pivot axis between the first end and the second end of the lever. When the first end of the lever is pressed by the tip of the moving paper and reaches a first position, the first sensor determines that the tip of the paper is entering the nip and generates a first sensing signal. When the first end of the lever is pressed by the tip of the moving paper and reaches a second position at which the paper has proceeded farther than at the first position, the first sensor determines that the tip of the paper passes through the nip and generates a second sensing signal.

An image forming apparatus comprises a main body having a mounting portion and a sensing portion disposed on one sidewall of the mounting portion. A developing unit assembly has a plurality of developing units and a contacting portion is disposed on one of the developing units. The contacting portion selectively contacts the sensing portion. The bottom surface of the mounting portion is declined to block the contacting portion from contacting the sensing portion prior to the installation of all of the developing units on the mounting portion. The angle of the bottom surface becomes larger when going towards the interior of the mounting portion. The contacting portion is installed on only one developing unit, but whether the other developing units are mounted can be sensed by using the contacting portion, thereby avoiding the use of multiple contacting portions. An image forming apparatus fabricated with this structure is smaller, simpler, and has reduced manufacturing costs.

A multi-function peripheral including: a printing portion; a scanning portion reading an image from a document; a discharge portion disposed between the printing portion and the scanning portion, and loading sheets of print media on which images are formed; and a finisher installed on the discharge portion to post-process the print media, on which the image is formed. The finisher includes: a plurality of fixing units including a first fixing portion disposed on a lower portion of the finisher in order to prevent the finisher from moving upward and a second fixing portion that can rotate so as to prevent the finisher from moving in an attaching direction on the discharge portion.
