摘要： An image forming apparatus includes a laser scanning unit that irradiates a light. A photoconductive medium forms thereon an electrostatic latent image using the light from the laser scanning unit. A developing roller transfers a developer onto the electrostatic latent image formed on the photoconductive medium to develop the electrostatic latent image. A transferring roller forms a transfer nip in tight contact with the photoconductive medium and transfers the developer attached on the photoconductive medium onto a paper passing through the transfer nip. A paper supplying part stacks the paper thereon. A pickup roller picks up the paper stacked on the paper supplying part. A paper edge sensor senses a top edge of the paper picked up by the pickup roller. The paper picked up by the pickup roller is directly supplied toward the transfer nip. A paper moving path is reduced, thereby minimizing the whole size of the image forming apparatus. Also, the number of parts is reduced, thereby decreasing material costs.

摘要： An apparatus and method for measuring a liquid level in a vessel using an acoustic wave. Acoustic tubes have first ends disposed vertically along a sidewall of the vessel for each of the liquid levels to be measured, and the tubes communicate with the inside of the vessel. Second ends of the tubes are connected to a common tube. A storage level sensor board generates the acoustic wave in the vessel, receives the acoustic wave propagated through the acoustic tubes and the common tube, and determines the level of liquid in the vessel based on the received acoustic wave.

摘要： A method of detecting the amount of remaining sheets of paper in a paper feeding cassette of a printing apparatus, wherein the printing apparatus receives a paper feeding cassette having a knock-up plate on which paper is placed, and which pivots as paper is removed therefrom, a pickup roller installed in the printing apparatus which elastically moves up and down within a predetermined range to contact the paper, the pickup roller being made to rotate in close contact with the paper to sequentially feed the paper into the printing apparatus, a lifting mechanism which lifts the knock-up plate step by step according to the consumption of paper, thereby placing the loaded paper against the pickup-roller, calculating a difference in the number of operations of the lifting mechanism for lifting the knock-up plate toward the pickup roller when a maximum number of sheets of paper is loaded into the paper feeding cassette and when only a single sheet of paper is placed in the paper feeding cassette, calculating an amount of consumed paper per one operation of the lifting mechanism as a set value from the calculated difference, lifting the knock-up plate when the paper feeding cassette enters into the printing apparatus until the loaded paper closely contacts the pickup roller, and counting the number of operations of the lifting mechanism, and calculating the amount of paper remaining in the paper feeding cassette based on the number of operations counted and the set value calculated. As a result, a user is always able to roughly determine how many sheets of paper are left in the cassette, thereby avoiding situations where the printing job is stopped due to a lack of paper.

摘要： An image forming apparatus includes a printing unit and a shutter arm unit. The shutter arm unit includes a shutter arm that swings to first and second positions, and a stopper arm, connected to the shutter arm, which protrudes toward a transportation path when the shutter arm swings to the second position in which the stopper arm prevents extra sheets of recording media from moving along the transportation path. The force of the paper moving along the transportation path swings the shutter arm unit into the second position, a protrusion cam and an escape cam prevent an increase in the return load of the shutter arm, and a pair of ends of the shutter arm aligns the front end of the sheet of paper.
