Abstract: An image photographing apparatus capable of maintaining the size of a sensor plate even in a case when the size of a shutter assembly is increased, the image photographing apparatus including a shutter assembly configured to control an amount of light entered, an image sensor disposed at a rear of the shutter assembly to change the light to an electrical signal, a sensor plate configured to support the image sensor, and a main frame configured such that the shutter assembly and the sensor plate are be mounted thereon, wherein the main frame includes a frame base, and a shutter mounting portion protrudedly formed from the frame base such that the shutter assembly is mounted in a sliding manner on the shutter mounting portion.

Abstract: An image photographing apparatus includes a main body including a lens unit, and a recording medium driving unit to drive a recording medium that records an image photographed through the lens unit, a recording medium cover openably attached to the main body of the image photographing apparatus to insert or to remove the recording medium to or from the recording medium driving unit, a locking unit to lock or unlock the recording medium cover, and a manual opening unit detachably attached to the main body of the image photographing apparatus to expose and allow the locking unit to be manually operated to remove the recording medium in a “no power” situation.

Abstract: An image photographing apparatus includes a main body and an external camera connected to the main body via a cable. The external camera includes a case having a receiving space, a cover rotatably connected to the case, and a camera module disposed in the receiving space. The camera module rotates when the cover rotates.

Abstract: A portable electronic device having a triaxial hinge structure which includes a first body, a second body, to rotate about a first hinge axis relative to the first body, a third body to rotate relative to the second body not only about a second hinge axis but also a third hinge axis, a first hinge unit, to enable the second body to rotate about the first hinge axis, a second hinge unit, to enable the third body to rotate about the second hinge axis, and a third hinge unit, to enable the third body to rotate about the third hinge axis.

Abstract: A microwave oven incorporating therein an air cooling system comprises an outer casing containing a cooking chamber and a compartment. The compartment is provided with an air intake opening. A magnetron and a high voltage transformer are positioned at upper and lower sides within the compartment, respectively. A cooling fan is disposed at a position near the high voltage transformer and forces cooling air around the microwave oven to enter the compartment through the air intake opening and to leave the compartment along a plurality of airflow routes. A screen plate is disposed between the high voltage transformer and the cooling fan and directs a part of the cooling air from the cooling fan to the magnetron so that the magnetron is directly cooled by the cooling air.
