FIG. 12 shows a perspective view schematically illustrating an embodiment of a card-type device (refer to Patent Document 1, for example). A card-type device 40 has a wireless communication function, and includes a circuit board 41, a flat housing 42 which accommodates the circuit board 41, and an antenna structure body 43 which is disposed outside of the housing 42 and which performs wireless communication utilizing radio waves. The antenna structure body 43 includes an antenna turning shaft 44 at a base end thereof, and the antenna turning shaft 44 projects from the antenna structure body 43. The housing 42 has a through-hole on one side which allows the antenna turning shaft 44 to be inserted into the housing 42. The housing 42 also has inside thereof a bearing (not shown) which receives the antenna turning shaft 44. With this configuration of the card-type device 40, the antenna structure body 43 turns on the antenna turning shaft 44, and the shaft 44 acts as the axis of turn. For example, when the card-type device 40 is used by being inserted into a card slot of an information terminal apparatus such as a personal computer, the antenna structure body 43 is turned so as to stand on an upper surface of the housing 42 as shown by a dashed line in FIG. 12. Thereby, the sensitivity to radio waves for transmission/reception is enhanced. On the other hand, when the card-type device 40 is detached from the card slot of the information terminal apparatus and is carried about, the antenna structure body 43 is turned into an accommodated flat position to be laid flat as shown by a solid line in FIG. 12. Thus, the card-type device 40 is readily carried.

In the configuration of the card-type device 40 shown in FIG. 12, in order to turn the antenna structure body 43 from the flat position to the upright position, the antenna structure body 43 is turned upward manually, for example, drawn up using a nail. The manual operation of turning the antenna structure body 43 upright is troublesome, and therefore, the device 40 is not user-friendly.
