An image forming apparatus includes a developing device, a plurality of feeding and delivering paths through which a printing medium is delivered to the developing device, a feeding roller unit which forms a developing and delivering path in which the plurality of feeding and delivering paths are joined and delivers the printing medium to the developing device, and a guide unit which guides the printing medium passing through the plurality of feeding and delivering paths to the feeding roller unit and is rotatably provided to expose the plurality of feeding and delivering paths to the outside. In the above configuration, the printing medium jam problems inside the image forming apparatus are easily cleared.

Image forming apparatus

A semiconductor device includes a single crystalline substrate, an electrical element and an optical element. The electrical element is disposed on the single crystalline substrate. The electrical element includes a gate electrode extending in a crystal orientation &#x3c;110&#x3e; and source and drain regions adjacent to the gate electrode. The source region and the drain region are arranged in a direction substantially perpendicular to a direction in which the gate electrode extends. The optical element is disposed on the single crystalline substrate. The optical element includes an optical waveguide extending in a crystal orientation &#x3c;010&#x3e;.

Semiconductor devices and methods of manufacturing the same

According to an example embodiment, a conductive paste includes a conductive powder, a metallic glass having a supercooled liquid region, and an organic vehicle. The metallic glass may include an alloy having a disordered atomic structure that includes at least two metals. An electronic device and/or solar cell may include an electrode formed using the conductive paste. An electrode formed using a conductive paste according to example embodiments may have lower contact resistance than an electrode formed using a conductive paste that includes glass frits instead of a metallic glass.

Conductive paste and electronic device and solar cell including an electrode formed using the conductive paste

An image forming apparatus includes a structure to lift or lower a paper loading tray without a separate drive source while preventing damage to constituent elements even under an abnormal situation in that excessive force is transmitted to the paper loading tray. The image forming apparatus includes a paper feeding cassette including a paper loading tray and a lifting member to lift or lower the paper loading tray, the paper feeding cassette being detachably coupled to the body, a power intermittence device to intermit power to be transmitted from a drive source provided in a body of the image forming apparatus to the lifting member, and a power transmission device to transmit the power transmitted through the power intermittence device to the lifting member by use of at least one worm gear. The image forming apparatus further includes a safety lever having one end to cooperate with a pickup roller assembly. The other end of the safety lever is pivotally rotatable between a first position where the other end of the safety lever restrains the power intermittence device so as not to transmit power to the lifting member and a second position where the other end of the safety lever is spaced apart from the power intermittence device so as to transmit the power to the lifting member.
