In this case, the knob is adapted to move the antenna back and forth through the base end of the antenna.
Since almost no load is applied to the tip of the antenna, the tip of the antenna does not fall off or bend and the antenna is not damaged, and the life of the antenna can be maintained for a long time.

According to a second aspect of the present invention, in the first aspect of the present invention, a slit is formed in the outer peripheral surface of the housing along a longitudinal direction of the storage section and communicates with the storage section. Are connected to the base end of the antenna through the slit.

According to the above configuration, the antenna can be smoothly moved in and out by moving the knob along the slit.

According to a third aspect of the present invention, in the second aspect, the case is formed in a vertically long box shape so as to fit in a palm, and the slit is formed on a side surface of the case. Features.

According to the above configuration, the knob can be operated by holding the housing with only one hand, and the operability is excellent.

According to a fourth aspect of the present invention, in any one of the first to third aspects, the knob is detachably connected to a base end of the antenna.

According to the above configuration, when the antenna is replaced, the connection between the base end of the antenna and the knob is released, the antenna is removed from the storage, and then a new antenna is stored in the storage. It is only necessary to connect the knob to the base end of the antenna, and the replacement can be easily performed.

According to a fifth aspect of the present invention, in the first aspect of the present invention, an engaging recess is formed at a base end of the antenna, and the knob is fitted into the engaging recess. The engaging recess is provided with an engaging projection that detachably engages with the engaging recess.

According to the above configuration, the knob can be easily connected to the base of the antenna simply by fitting the engagement protrusion of the knob into the engagement recess formed in the base of the antenna. And the connection can be easily released.

According to a sixth aspect of the present invention, in any one of the first to fifth aspects of the present invention, the housing is a mobile phone housing.

According to the above configuration, the mobile phone can be easily moved in and out without damaging the antenna.

[0019]

Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1 and 2 show a mobile phone according to an embodiment of the present invention. The mobile phone is provided along a storage unit 6 on a side surface of a case 1 formed in a vertically long box shape so as to fit in a palm. A slit 13 communicating with the portion 6 is formed, and a knob portion 14 is connected to the antenna base end portion 7b through the slit 13. FIGS. 5 and 6 show other configurations.
Are substantially the same as in the conventional example shown in FIG.

The knob portion 14 is made of a synthetic resin material, and as shown in FIGS. 3 and 4, a rectangular plate-shaped knob portion main body 14a which comes into contact with or approaches the side surface of the housing 1, and the knob portion main body. A pair of elastically deformable protrusions 14b which are integrally and protruded in parallel at a predetermined interval on the back surface of the protrusions 14a and are inserted into the slits 13, and a substantially triangular shape integrally formed at the tip of each of the protrusions 14b. The outer surface of each of the engaging protrusions 14c is an inclined surface 15 that is inclined inward toward the tip, and the rear end of the inclined surface 15 is
The protruding portion 16 protrudes outward from the outer side surface of b.

An engaging recess 17 having a substantially T-shaped cross section is formed on the side surface of the antenna base end portion 7b so as to face the knob portion 14. Reference numeral 18 denotes an elastically deformable dust infiltration prevention sheet made of a nonwoven fabric or the like closing the slit 13, and a cut 19 through which both projecting pieces 14 b can pass is formed in the center of the sheet over substantially the entire length of the slit 13.

In the above configuration, when the knob 14 is connected to the antenna base 7b in the housing 6, the knob main body 14a is gripped, and the two engaging projections 14c are engaged with the slit 13 through the slit 13. What is necessary is just to push in the recessed part 17. As a result, the inclined surface 15 of each engagement protrusion 14c is
7, the two projecting pieces 14b are elastically deformed inwardly so that the two engaging projections 14c are engaged with the engaging recesses 1.
5, the projection 16 of each engagement projection 14c is engaged with the inner surface of the engagement recess 17, and the knob 14 is securely attached to the antenna base end 7b. it can.

When talking, the user holds the housing 1 and pushes up the knob 14 with his thumb to cause the antenna 7 to protrude from the storage unit 6 (see phantom lines in FIGS. 1 and 2).
After the end of the call, contrary to the above, the thumb 7 may be pressed down with the thumb to retreat the antenna 7 into the housing 6.

In this case, the antenna 7 is moved back and forth via the antenna base end 7b by the knob portion 14. Since almost no load is applied to the antenna front end 7c, the antenna front end 7c falls off. The antenna 7 can be maintained for a long time without being damaged by the antenna body 7a being bent or bent. In addition, the knob 1 can be operated by holding the housing 1 with only one hand, and the operability is excellent.

When exchanging the antenna 7, the two projecting pieces 1
4b, the two engaging protrusions 14c are brought closer to each other, so that the engaging state between the protrusion 16 of each engaging protrusion 14c and the engaging recess 17 is eliminated, and the knob main body 14a is pulled. After the two engaging projections 14c are removed from the engaging recesses 17, the screwing of the retaining nut 9 is released,
The antenna 7 is removed from the storage unit 6 and a new antenna 7
After the retaining nut 9 is screwed into the storage portion 6, the engaging protrusion 14 c of the knob 14 may be fitted into the engaging recess 17 through the slit 13.

In the above-described embodiment, a portable telephone has been described as an example. However, the present invention is not limited to this, and can be applied to various types of communication devices with an antenna.

[0027]

According to the first aspect of the present invention, the antenna is moved back and forth through the base end of the antenna by the knob, and almost no load is applied to the front end of the antenna. The part does not fall off or the antenna bends without being damaged.
The life of the antenna can be maintained for a long time.

According to the second aspect of the present invention, the antenna can be smoothly moved back and forth by moving the knob along the slit.

According to the third aspect of the present invention, the handle can be operated by holding the housing with only one hand, and the operability is excellent.

According to the fourth aspect of the present invention, when the antenna is replaced, the connection between the base end of the antenna and the knob is released, the antenna is removed from the storage, and a new antenna is inserted in the storage. , And simply connect the knob to the base end of the antenna, and the replacement operation can be easily performed.

According to the fifth aspect of the present invention, the engaging portion is simply fitted into the engaging concave portion formed on the base end portion of the antenna, and the knob portion is easily inserted into the base end portion of the antenna. The connection can be made, and the connection can be easily released.
