Patent ID: 8040282

Claim:
A card-type device comprising: a housing; a circuit board within the housing; an antenna body disposed outside of the housing; a turning shaft connected to the housing and configured to allow the antenna body to turn between a first position in which the antenna body stands substantially upright relative to a surface of the housing and a second position in which the antenna body lies substantially flat relative to the surface of the housing; an antenna turning member configured to apply an urging force to the antenna body in a direction in which the antenna body turns toward the substantially upright position on the turning shaft; a locking mechanism that includes a locking projection positioned on one of the antenna body and the housing, and a corresponding locking portion positioned on the other of the antenna body and the housing, the locking portion being fitted to the locking projection when the antenna body is in the second position and which stops the antenna body from turning in a direction toward the first position due to the urging force applied by the antenna turning member; and a locking elastic member configured to apply an urging force to the antenna body in a locking direction along the turning shaft; wherein in a state in which the locking projection is fitted to the locking portion, when the antenna body moves along the turning shaft in an unlocking direction, the locking projection is released from the locking portion, and the antenna body turns in the direction toward the first position.
