The slide operation groove 121 is formed through the cover plate 120 so as to correspond to the position where the operation means 230 is formed. The operating means 230 is inserted into the slide operation groove 121 and the operating means 230 is exposed to the outside of the main body 100. [ The slide operation groove 121 is formed so that the sectional area of the slide operation groove 121 gradually decreases from the outer side to the inner side of the main body 100. That is, the slide operation groove 121 is formed so as to be recessed inward of the main body 100, and the uppermost end of the slide operation groove 121 and the uppermost end of the operation means 230 are arranged on the same line. Therefore, the operating means 230 is not formed to protrude out of the cover plate 120, and the operating means 230 is caught by other means to prevent unexpected unlocking of the door. Also, since the slide operation groove 121 is formed so that its cross-sectional area gradually decreases from the outer side to the inner side of the main body 100, even if the width of the operation means 230 is small, the user can operate the slide operation groove conveniently.

4, the door fixing device according to the first embodiment of the present invention includes a first fixing means 300 and a second fixing means 300 on a metal plate 410 of a second fixing means 400, And the first fixing means 300 is coupled to the plate 410 by the magnetism of the first fixing means 300. [ Therefore, the moving plate 210 and the engaging member 220 coupled with the first fixing means 300 also maintain a fixed state. When the user moves the operation means 230 in the right direction of FIG. 4 by applying an external force to the operating means 230, the moving plate 210 and the engaging member 220 coupled thereto are moved, Protrudes out of the main body 100. At this time, the external force applied by the user to the operation means 230 should be stronger than the magnetic force of the first fixing means 300. [ The protruding latching member 220 is inserted into the latching groove 11 of the chassis 10 to fix the door. Since the first fixing means 300 is still in contact with the plate 410 even after the door is fixed, the moving plate 210 and the engaging member 220 are also held in a fixed state by the magnetism of the first fixing means 300 . That is, before the user applies an external force larger than the magnetic force of the first fixing means 300, the moving plate 210 and the engaging member 220 are kept in a fixed state, and the door is unintentionally Thereby preventing it from being opened. Further, the depth of the main body 100 to be embedded in the accommodation space 110 can be made very small, and the size of the fixing device can be reduced in size. In addition, since the magnetic material has no elasticity deterioration due to long-term use in an elastic member such as a spring, it is possible to prevent deterioration of locking function due to long-term use.
