  That is, the reel lock mechanism 14 includes a lock member contact surface of a lock member engaging portion 15 provided on the reel member 13 (an annular convex portion 13b formed on the outer periphery of the tip end portion of the bearing tube 13a of the reel member 13). A surface having a steep angle with respect to the circumferential surface of the reel member 13 is received by the lock member 16 to prevent the reel member 13 from rotating in the wire feeding direction (the closing direction of the lid portion 6). Further, when a rotational force is applied to rotate the reel member 13 in the wire feeding direction with a force larger than the spring force of the lock member pressing spring, the lock member 16 resists the spring force and engages with the lock member. The reel member 13 is released from the lock member contact surface of the joint portion 15 to release the lock, and the reel member 13 is allowed to rotate in the wire feeding direction.

  Note that the positional relationship between the two locking member engaging portions 15 of the reel member 13 and the locking member 16 is such that the protruding length of the rod antenna 12 is predetermined by the reel member 13 with respect to the main body case 2. When the reel member 13 rotates in the wire feeding direction until the value reaches the value, the lock member contact surface of one of the lock member engaging portions 15 of the reel member 13 is received by the lock member 16, and the reel member 13 is When the main body case 2 is rotated substantially 180 degrees from the antenna protruding state, that is, the antenna retracting wire 18 is wound around the reel member 13, and the rod antenna 12 is pulled out at the leading end of the knob 12a. When the lock member engagement surface 15 of the lock member engaging portion 15 on the opposite side of the reel member 13 is stored in the lid portion 6 with the lock portion being stored, It is set to be received by 16.

  On the other hand, the bearing tube 13a provided at the center of the reel member 13 is provided with a spring force of the lock member pressing spring on the shaft member 11, that is, the lock member against the peripheral surface of the annular convex portion 13b of the reel member 13. Thus, the reel member 13 is constrained by the reel lock mechanism 14 when the lid portion 6 is opened and rotated. And rotate integrally with the lid 6 without any change.

  Although not shown in the figure, a control unit including a microphone element, a power supply unit, a key input unit, a transmission / reception circuit, and the like is provided in the main body case 2, and in the lid case 7. A liquid crystal display element, a speaker element, a solid-state imaging element, and a drive circuit thereof are provided.

  The antenna lead-in wire 18 also serves as an antenna connection wiring. The drive circuit for the liquid crystal display element and the solid-state image sensor and the antenna lead-in wire 18 are leads (not shown) formed on the reel member 13 and the shaft member 11, for example. It is connected to the control part in the main body part case 2 through a flexible lead provided through the through part.

  Further, the cellular phone of this embodiment includes means for detecting the retracting and protruding of the rod antenna 12, and the antenna storing / protruding detecting means is, for example, a part of the outer periphery of the reel member 13 opposite to each other. That is, the switch operating projections 19 projecting from two portions that are shifted by the same angle as the opening / closing rotation angle (substantially 180 degrees) of the lid 6, and provided in the lid case 7, The microswitch 20 is turned on by one contact of the operating projection 19 and turned off by the other contact.

  In this cellular phone, when the received radio wave is weak in the state in which the rod antenna 12 is stored and there is a possibility of causing a transmission / reception error, the mobile phone displays the fact on the display unit 8 without starting transmission / reception. A function of starting transmission / reception when the rod antenna 12 is projected is provided.

  As shown in FIG. 1, the mobile phone is used by rotating the lid 6 so as to project outward from the main body 1 and projecting the rod antenna 12 as necessary. The lid 6 is closed and rotated so as to overlap the front surface of the main body 1 after use.

  When the lid 6 is closed and rotated, the reel member 13 in the lid case 7 is locked to the main body 1 by the reel lock mechanism 14 so as not to rotate. Therefore, the lid 6 With the closing rotation of the antenna, the antenna retracting wire 18 is wound around the reel member 13, and the rod antenna 12 protruding in use is retracted and stored in the lid portion 6.

  That is, this mobile phone connects the base end of the rod antenna 12 provided in the lid case 7 and the reel member 13 rotatably provided in the lid case 7 by the antenna lead-in wire 18, and A reel lock mechanism 14 is provided for locking the reel member 13 to the main body 1 in a rotation-prevented state when the lid 6 is closed, and the lid case 7 is opened when the lid 6 is opened. The rod antenna 12 projecting outward is wound around the reel member 13 locked by the reel lock mechanism 14 with the lid 6 being closed and rotated, and the antenna pull-in wire 18 is taken up. 6, according to this mobile phone, the rod antenna 12 is automatically bent and folded in conjunction with the closing rotation of the lid portion 6. It can be stored without causing.

  The mobile phone may be used without projecting the rod antenna 12. In this case, the reel lock mechanism 14 causes the main body 1 to move to the main body 1 as the lid 6 is closed. On the other hand, the antenna pull-in wire 18 is wound around the reel member 13 locked in the rotation prevention state.

  However, at this time, since the pulling knob 12a at the tip of the rod antenna 12 is received by the end surface of the lid case 7, the antenna retracting wire 18 is tensioned as the lid 6 is closed. The tension of the antenna pulling wire 18 acts on the reel member 13 in the same manner as the rotational force that rotates the reel member 13 in the wire feeding direction with a force larger than the spring force of the lock member pressing spring. Since the lock member 16 is separated from the lock member contact surface of the lock member engaging portion 15 of the reel member 13 against the spring force to release the lock of the reel member 13, the reel member 13 is As the cover 6 is closed and rotated, the cover 6 rotates integrally with the cover 6.

  Therefore, when the cellular phone is used without protruding the rod antenna 12, the antenna retracting wire 18 is not further wound around the reel member 13 as the lid portion 6 is closed, so that the rod antenna The lid 6 can be closed and rotated without applying an excessive load on the antenna 12, the antenna retracting wire 18, and the reel member 13.

  Further, when the lid portion 6 is opened and rotated when the mobile phone is used, as described above, the reel member 13 has a friction between the bearing tube 13a and the shaft member 11 provided in the main body case 2. Because the force rotates together with the lid portion 6 without being restrained by the reel lock mechanism 14, the antenna retracting wire 18 is drawn out from the reel member 13 and is loosened when the lid portion 6 is rotated. There is nothing.

  When the rod antenna 12 is projected, the reel lock mechanism 14 rotates the reel member 13 in the wire feeding direction to release the lock of the reel member 13 when the rod antenna 12 is projected, and the rod The antenna 12 can be projected out of the lid 6 without difficulty.

  That is, the rod antenna 12 is pulled out of the lid 6 by pulling the pulling knob 12a at the tip, and when the rod antenna 12 is pulled with a certain force or more, the lock member 16 becomes the reel member. Since the reel member 13 is released from the lock member engaging portion 15 and the lock of the reel member 13 is released, the rod antenna 12 can be pulled out from the reel member 13 by pulling out the antenna retracting wire 18 without difficulty.

  In the mobile phone of this embodiment, the reel member 13 is provided so as to be rotatable about the shaft member 11 provided perpendicularly to the front surface of the main body 1 in the direction around the axis. Of the case of the main body and the lid, the diameter of the reel member 13 is increased without increasing the thickness of the lid portion case 7 provided with the reel member 13, and the winding and feeding length of the antenna retracting wire 18 are increased. It can be ensured sufficiently according to the predetermined antenna protrusion and retracting stroke.

  In addition, the mobile phone is provided with the lid 6 so as to be capable of opening and closing in a direction along a plane parallel to the front surface of the main body 1 around the shaft member 11, and the reel member 13 is provided on the shaft member 11.
