Abstract: A PDA terminal is provided. The PDA terminal includes: a main body; a processor disposed in the main body; a memory accessible by the processor; and a display unit disposed on a front surface of the main body to display information processed by the processor. A rear cover detachable from the main body is disposed on a rear surface of the main body. After the rear cover is removed, a gun handle is usable in a state of being connected to a coupling part formed under the rear cover. Since the gun handle with a switch is usable in a state of being connected to the main body of the PDA terminal, the operation of the PDA operation can be more conveniently used in an industrial site or the like.
