A card-type device that includes an antenna body disposed on a housing and movable along a turning shaft between an upright position and a flat position. An antenna turning member applies an urging force to the antenna body in a direction in which the antenna body turns to the upright position. A locking projection projecting and a corresponding locking portion which is fitted to the locking projection when the antenna body is in the flat position, stops the antenna body from turning. When the antenna body moves in a direction in which the antenna body is to be unlocked, the locking projection is released from the locking portion, and the antenna body automatically turns toward the upright position by the urging force of the antenna turning member.
