The portable electronic device of claim 9, wherein the support member has a first holding groove, the upper cover case has a second holding groove, the torsion element is a torsion spring and comprises: a torsion spring body a fixed end connected to the torsion spring body and disposed in the second holding groove; and a free end connected to the torsion spring body and disposed in the first holding groove. The portable electronic device of claim 9, wherein the first engaging structure is a hook, the upper cover housing has a second engaging structure, and the second engaging structure is a card slot, the activity The device further includes: a pushing portion protruding from the other side of the body, when the movable member rotates relative to the cam member and moves toward the first engaging structure, the pushing portion pushes against the hook, so that The hook leaves the card slot. The portable electronic device of claim 11, wherein the cam member has a first cam circumference and a second cam circumference, and when the abutting portion abuts the first cam circumference, and the upper cover housing is opposite to the When the base housing is rotated and opened, the movable member rotates relative to the cam member, and the abutting portion The abutting portion drives the body to move toward the first engaging structure and compresses the elastic member, and the body drives the pushing portion to push against when the first cam periphery rotates to abut the second cam periphery. The hook is such that the hook leaves the slot. The portable electronic device of claim 12, wherein the movable member rotates relative to the cam member when the abutting portion abuts the second cam periphery and the upper cover housing is rotatably closed relative to the base housing. And the elastic member provides the elastic force to move the movable member to the cam member to move and reset when the abutting portion rotates to abut against the circumference of the first cam, and the pushing portion is away from the Card slot. The portable electronic device of claim 13, wherein the first cam circumference is a plane, the second cam circumference is a curved surface, and one end of the first cam circumference is connected to the rotating shaft, and the first cam circumference is The other end extends outwardly of the shaft, and the second cam periphery is coupled to the other end of the first cam circumference. The portable electronic device of claim 9, wherein the supporting mechanism further comprises: a guiding member, one end is disposed on the upper cover housing, and the other end is movably disposed on the body of the movable member, and the The elastic member is sleeved on the guiding member. The portable electronic device of claim 9, wherein the upper cover case has a side wall, and the support member is adjacent to the torsion element when the torsion element is rotated to deform to enable the support member to support the upper cover case. One side stops against the side wall.
