The electronic device may have a slot for mounting an IC card, and the IC card may be inserted into the electronic card while being mounted on a tray. Using a tray for inserting an IC card improves waterproofness and a sense of unity in appearance of the electronic device.

The tray may need to be ejected from the electronic device in order to perform tasks such as changing a wireless communication network operator, roaming, or changing a memory card. A pin hole for inserting a tool such as an ejector pin is formed in the tray, and when a user inserts an ejector pin into the pinhole and presses it, a lever in contact with the tray is pressed to eject the tray.

7 is a plan view, an enlarged view, and a side view illustrating a second step of inserting the card tray 301 of the electronic device 101 according to the present invention.

8 is a plan view, an enlarged view, and a side view illustrating a first stage of an ejection operation of the card tray 301 of the electronic device 101 according to the present invention.

9 is a plan view, an enlarged view, and a side view illustrating a second stage of an ejection operation of the card tray 301 of the electronic device 101 according to the present invention.

Referring to FIG. 6 , in the first step of inserting the card tray 301, when the user inserts (PUSH) the card tray 301 from the outside, the card tray 301 is inserted into the card socket 401. And, the push head 511 may press one end of the card tray 301 by the elastic force of the elastic member 530 . Referring to FIG. 7 , in the second step, when the push bar 510 is inserted into the housing 520 as much as the first length D2, the elastic lug 512 of the push bar 510 extends to the housing 520. ) is caught inside, and the card tray 301 may not be pressed despite the elastic force applied to the push bar 510 by the elastic member 530 . In this step, the insertion operation of the card tray 301 may be completed.

The ejection operation of the card tray 301 may be started after the aforementioned insertion operation of the card tray 301 is completed. Referring to FIG. 8 , in the first step of the ejection operation, the user may additionally insert (PUSH) the card tray 301 to eject it. When the push bar 510 is further inserted into the housing 520 by the second depth D1, the elastic lug 512 may be released from being caught. Referring to FIG. 9 , the state in which the elastic lug 512 is caught in the housing 520 is released, so that the elastic member 530 presses the push bar 510 in the second step of the ejection operation, and thus the push head ( The card tray 301 may be ejected (EJECT) by operation 511 .

Referring to the side view (c) of FIG. 6, in the second step (STEP 2) of the card tray 301 insertion operation, when the user presses the card tray 301 in the -x axis direction to insert the card, The elastic lug 512 of the push bar 510 may move while being elastically deformed downward (a1 direction) along the hook-shaped first inclined surface 521a of the hooking portion 521 formed in the housing 520 . Referring to the side view (c) of FIG. 7 , in the second step of the insertion operation, when the card tray 301 is inserted by the first depth D2, the downward elastic deformation of the elastic lug 512 is partially released. , the elastic lug 512 may be moved upward (a2 direction in FIG. 7A) and caught on the hooking portion 521 by the snapping action. When the elastic lug 512 is caught on the hooking part 521, the elastic force applied to the push bar 510 by the elastic member 530 is not transmitted to the card tray 301, so the card tray 301 is in an inserted state. can keep

Referring to the enlarged view (b) of FIG. 6C, in the first step of ejecting the card tray 301, the user additionally presses the card tray 301 to insert the card tray 301 to the second depth D1. In this case, the elastic lug 512 of the push bar 510 may be formed on the second inclined surface 522a formed on the release part 522 of the housing 520 and/or on the portion of the elastic lug facing the second inclined surface. It can be moved while being elastically deformed in the lateral direction (for example, in the b1 direction) by the inclined surface 512a. Referring to the side view (c) of FIG. 8 , in the first step of the discharging operation, when the elastic lug 512 is elastically deformed laterally, the elastic lug 512 may be released from the jammed state. Therefore, the elastic lug 512 can escape from being caught by the hooking part 521 by snapping upward (for example, in the b2 direction) by the remaining elastic force in the z-axis direction. Thus, the push bar 510 may no longer be caught within the housing 520 . Therefore, in the second step of the ejection operation, the elastic force applied to the push bar 510 by the elastic member 530 is transmitted to the card tray 301, and the card tray 301 can be ejected in the x-axis direction. .

The tray ejection device 501, in which a push-lock push-release mechanism is implemented by such a snap action, has a space required for the rotational operation of the cam, as opposed to a cam or other mechanism similar thereto. Since it is not occupied, the space occupied inside the electronic device 101 is reduced. In addition, since the locking and releasing operations are performed with a minimal insertion process, the user can easily insert and eject the card tray 301 .
