An image forming apparatus including a power transmission unit having a driving source, at least one image receptor which is rotatably driven by the driving source and on which a latent image is formed by exposure, and a power transmission unit which transmits power from the driving source to the image receptor. The power transmission unit includes an image receptor axial gear formed on the same axis as the image receptor, and a plurality of intermediate gears which transmits the power from the driving source to the image receptor axial gear. The number Tn of teeth of an n-th one of the plurality of intermediate gears with respect to the image receptor axial gear satisfies the following Inequality: (I/Rn)−0.2≦Tn≦(I/n)+0.2, where, Rn is a reduction ratio from the n-th intermediate gear to the image receptor axial gear and I and n are a natural number.

A handler for sorting semiconductor chips after they have been tested includes a loading unit for loading chips to be tested and an unloading unit for unloading chips that have been already tested. Chips arrive in trays at the loading unit, and a loading picker removes the chips from the tray. When a tray is empty, it is moved over to the unloading unit by a tray transfer mechanism so that tested chips can be placed back into the tray. The tray transfer mechanism rotates the empty trays upside down as it is moved from the loading unit to the unloading unit to ensure that the tray is completely empty before it arrives at the unloading unit.

A skew adjusting apparatus is provided for an image forming apparatus having a plurality of skew adjusting parts arranged in a plurality of laser scanning units, respectively. The automatic skew adjusting apparatus comprises a driving source, an actuating part arranged on a driving shaft of the driving source so that the actuating part can be selectively connected with one of the skew adjusting parts depending on a position of the driving source. The actuating part actuates the connected skew adjusting part as the driving shaft rotates. A positioning part moves the driving source and a power transmission part transmits or cuts off the power of the driving source to the positioning part so as to move the driving source or stop the movement of the driving source.
摘要:
A wet-type image forming apparatus includes an intermediate transfer medium for receiving images which are formed in a plurality of photosensitive media and overlapped thereon to form an image and transferring the image to a print medium. The intermediate transfer medium runs along a predetermined path. A drying unit heats the intermediate transfer medium to evaporate part of carrier included in the image on the intermediate transfer medium before the image is transferred onto the print medium. A cooling unit cools the heated intermediate transfer medium after the image is transferred onto the print medium by making the intermediate transfer medium directly contact a coolant.
