In general, the term “portable communication device” refers to a device that a user can carry and perform wireless communication with a counterpart. Such portable communication devices are referred to as HHP, CT-2 cellular phones, digital phones, PCS phones and PDAs, and are classified into various types in appearance. For example, portable terminals are classified into bar-type, flip-type, or folder-type wireless terminals according to their appearance. Bar-type wireless terminal means that the single housing is configured as a bar-type, flip-type portable terminal means that the flip or cover is rotatably configured by a hinge device in the bar-type housing, folder-type portable The terminal means that the folder is configured to be rotatably connected to the single bar-type housing by a hinge device and to be folded. In addition, the portable terminal may be classified into a neck wearable type or a wrist wearable type according to a body wearing position or a wearing method. A necklace-type portable terminal means a portable method of wearing the terminal around the neck using a string, and a wrist-type portable terminal means a portable method of wearing the terminal on the wrist. In addition, portable terminals may be classified into rotation-type, sliding-type, and sliding / sliding swimg type wireless terminals according to the opening and closing method. The rotatable-type portable terminal means that two housings are rotatably connected and opened while facing each other, and the sliding-type portable terminal is one of two housings in which one housing is faced by longitudinal sliding movement. It means to open and close. In addition, the sliding / rotating type portable terminal refers to rotating one of the housings in the longitudinal direction after moving one of the two housings.
