BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a case locking device of a portable terminal, and more particularly, to a case locking device of a portable terminal configured to be detachable and exchanged with a case of a terminal in response to a pressing.

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, wireless terminals are classified into bar-type, flip-type, or folder-type wireless terminals according to their appearance. The bar-type wireless terminal means that the single housing is configured as a bar-type, and the flip-type wireless terminal means that the flip or cover is rotatably configured by the hinge device in the bar-type housing. The terminal means that the folder is configured to be rotatably connected to the single bar-shaped 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 wireless terminal refers to a portable method of wearing a terminal around a neck using a string, and a wrist-type wireless terminal refers to a portable method of wearing a terminal to a wrist. In addition, the wireless terminal may be classified into a rotation-type or sliding-type wireless terminal according to an opening and closing method. The rotatable wireless terminal means that two housings are rotatably connected and opened while facing each other, and the sliding-type wireless terminal is one of two housings, in which one housing is faced by longitudinal sliding movement. It means to open and close. The variously classified wireless terminals listed above will be readily understood by those of ordinary skill in the art.

In addition, such a portable communication device has been rapidly spread and used with the radical development of information and communication technology as it enters the information society, and is becoming a necessity of life.

The portable communication device has been gradually reduced in weight and size in order to facilitate carrying, and recently, small portable terminals are enough to fit in the palm of a hand.

There is a tendency to emphasize the appearance design of the mobile terminal especially among young people, and to decorate the mobile terminal beautifully by attaching various ornaments or dolls with a strap.

Various kinds of ornaments of such portable terminals are established as a business, and manufacture and sell the ornaments of portable terminal devices.

The portable terminal plays a role of representing itself by attaching ornaments, that is, accessories (accessory) made of ornaments such as preferred toys, strings, and rings to the terminal to decorate their own personality and fashion.

In addition, younger generations who are sensitive to fashion tend to see and purchase the appearance design of mobile phones. To meet this trend, mobile phones of various colors and shapes have been developed.

In the case of the conventional mobile terminal, a method of inducing a change in gloss by processing after spraying a specific color and a method of inducing two color changes according to the change of light have become mainstream in the mobile phone market.

However, the conventional portable terminal is sprayed with a specific case of the exterior case, when processing, if the user wants to change to a different color with a new terminal to change itself, or the case is made of stickers and textiles or leather materials There is a problem in that the cost due to the purchase of a separate new terminal and the auxiliary case to be used by combining the case. Since the auxiliary case is inserted into the case of the terminal and coupled, it is difficult to separate when changing to another auxiliary case.

In addition, the conventional portable terminal has a disadvantage in that the case of the portable terminal, such as discoloration, partial damage and scratches, or the design of the long-term use of the mobile terminal has a long time use.

Accordingly, the present invention is to solve the above-mentioned conventional problems, an object of the present invention, by configuring a case locking unit for detaching the exterior case from the terminal in accordance with the pressing on a predetermined position around the side of the terminal, the exterior case of the terminal It is to provide a case locking device of a mobile terminal to facilitate the exchange of.
