Description
2319417 i PORTABLE RADIO APPARATUS
BACKGROUND OF THE INVENTION
The mresent invention relates to a portable radio communication apparatus, and more particularly to an antenna arrangement for a portable radio communication apparatus.
In a conventional typical portable radio apparatus, an antenna and a receiver are disposed on an upper portion of the portable radio apparatus body. In particular, the receiver is fixed to the portable radio apparatus body, and a transmitter is provided in a lower portion of the body. In such a conventional portable radio apparatus, since the receiver is brought in close contact with the ear when calling, the antenna inevitably approaches the human head.
15' Thus, during calls m-ade with the antenna close to the human head, the radio waves transmitted from or received by the antenna are adversely affected by the head, as a result of which there arise such problems that the radiation pattern o'iL the transmitted radio waves gets warped, radio waves transmitted from certain directions are difficult to receive, and the reception sensitivity is liable to deteriorate.
- 2 Conventionally, as a portable radio apparatus in which such problems are solved, there has been known a structure in which an antenna is disposed on a side portion or on a lower portion of the apparatus body, as shown in Japanese Laid Open Patent Application Nos Sho 63-67032 and Hei 4127723. Further, as a different type, there has been proposed a portable radio apparatus having a structure in which radio waves are not radiated in the vicinity of the head, as disclosed in Japanese Laid Open Patent Application No Sho 59-92629.
SUMMARY OF THE INVENTION
An object of at least the preferred embodiments of the present invention is to provide a novel portable radio apparatus which is capable of reducing the influence of the human head on radio waves transmitted from or received by an antenna as much as possible when calling.
The present invention provides a portable radio apparatus, comprising a body, a receiver provided in said body, and an antenna capable of being freely accommodated in and drawn out from said body, said antenna being previously formed in a curved shape and bent in a direction in which said antenna is spaced apart from said receiver when said antenna is drawn out from said body and in use is directed away from the operator's head. With such a structure, at the time of calling, when the receiver is drawn out from the portable radio apparatus body to the human ear side so as to be brought into contact with the ear, since the antenna is away from the head to a certain degree, the influence of the head on the radio waves transmitted from or received by the antenna is reduced.
In most embodiments, the antenna projects out of a plane substantially parallel to the side of the operator's head.
As used herein the terms "receiver" and "transmitter" may include the complete receiver or transmitter, or just the transducer portion thereof (loudspeaker or microphone) or any intermediate combination of the transducer and part or all of its associated electronic circuitry, the remainder of the circuitry for example being housed in the body portion of the apparatus.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Figs. 1A and 1 B show, as an example of a portable radio apparatus, a radio apparatus, a portable telephone in which an antenna 2 is withdrawably accommodated in a portable radio apparatus body 1. A receiving portion 8 on which a receiver 3 is mounted is fitted by means of a hinge portion 7 to an upper portion of the body 1, and a transmitter 4 is provided on a lower portion of the body 1. In a non-call state, the antenna 2 is accommodated in the portable telephone body 1, and also the receiver 8 is in close contact with the portable telephone body 1 so that the portable transceiver body is compact. In a call state, as shown in Fig. 1B, the antenna 2 is drawn out from the portable telephone body 1, and the receiving portion 8 can be raised up from the portable telephone body 1 to,the ear of the user by rotation of the hinge 7.
Fig. 2 is a diagra-m showing an operating condition of the portable telephone. As shown in the figure, when the receiver 3 of the body 1 is brought into close contact with the ear, the antenna 2 can be kept far apart from the head 5 of the user in commarisDn with a conventional operating condition shown in Fig. 3.
Figs. 4A and 4B show an example of a mechanism in which, when the antenna 2 is drawn out from the portable telephone body 1 in a call state, the receiving portion 8 is can be automatically moved away from the portable telephone body 1.
Fig. 4A shows a state in which the antenna 2 is accommodated in the portable telephone body 1, whereas Fig. 4B shows a state in which the antenna 2 is drawn out from the body 1. A cord 18 is attached to the end of the antenna 2-and wound on the periphery of a pulley 15 via a roller 16. A gear 11 is fixed to the pulley 15 which rotates with the gear 11, whereas a gear 12 whi-ch interlocks the gear 11 is fixed to the receiving portion 8. A hinge 7 is provided on the receiving portion 8 in such a manner that the receiving portion 8 is rotated by 6 - rotation of the gear 12. A spiral spring 13 is fitted to the hinge 7 in such a manner that a clockwise rotational force is always exerted on the receiving portion 8 by the elastic force of the-spiral spring 13 so that force is applied to the receiving portion 8 in the direction in which the receiving portion 8 is accommodated ii-r the portable telephone body 1. A spring-like claw 17 for stopping the antenna 2 is disposed on the antenna 2 so that the antenna 2 is not retracted again when it is 10 drawn out. from the body 1.
In the portable telephone thus constituted, when the antenna 2 is draw-in out, the cord 18 is drawn in the direction indicated by an arrow (see Fig. 4B), to thereby make the pulley 15 rotate in the direction indicated by an arrow. As a result, the rotates so that the hinge 7 gear 12 as well as the gear 11 which supports the receiving portion 8 is rotated against the clockwise rotational force applied by the spiral spring 13, whereby the receiving portion 8 is rotated so as to be move away from the body 1 and be raised up as shown in the Fig. 4B. When the antenna 2 has been drawn out, force is exerted on the antenna 2 in a direction in which the antenna 1 is drawn in. However, since the antenna 2 is stopped by the claw 17, the receiving portion 8 is also kept apart from the body 1.
Figs. SA and 5B show another portable telephone.
7 In the figures, a portable telephone body 1 includes an antenna 2, a receiver 3 on an upper portion thereof, and a transmitter 4 on a lower portion thereof. In a non-call state, the antenna 2 is accommodat-ed in the portable telephone body 1, and the receiver 3 is also accommodated in the portable telephone body 1 so that the portable telephone is made compact. On the other hand, in a call state, as shown in Fig. 5B, the antenna 2 is drawn out and a receiving portion 8 per se containing the receiver 3 therein projects from the portable telephone body 1, as shown in Fig. 5B. Therefore, when the receiver 3 is brought into close contact with an ear of an operator, since the upper portion of the portable telephone body 1 is moved away from the ear, the antenna 2 is also inevitably moved away from the head of the operator.
The receiving portion 8 may be modified as shown in Figs. 9A and 9B. The receiving portion 8 shown in Figs. 9A and 9B is fitted by means of a hinge to the body 1 so that it freely projects from the body 1.
The antenna 2 and receiver 3 may be drawn out by hand, and fixed with respect to the portable telephone body 1 by a spring like claw. Alternatively, as in the mechanism shown in the Figs. 4A and 4B, there can be provided a mechanism in which the antenna 2 is - 8 drawn out to automatically project the receiver 3 from the Portable telephone body 1 to the human ear.
Embodiments will be described in which an antenna is drawn out from the back, the side or the like of a portable telephone body to remove the influence of the human head on the antenna.
Referring to Fig. 6, a portable telephone body 1 includes a front surface 21 with a receiver, a back surface 22 opposed to the front surface 21, and an upper surface 24 which is nearest the receiver among surfaces adjacent to the front surface 21 and the back surface 22. An antenna 2 is previously formed in a curved shape so as to be bent in a direction in which the antenna 2 moves away from the receiver (front surface 21) when it is drawn, and projects from the upper surface 24 of the body 1. Further, as shown in Fig. 7, an antenna 2 may be projected from a middle portion of the back surface 22 of the portable telephone body 1.
Further, as shown in Fig. 8A, in the case of the portable telephone shown in Fig. 6, the antenna 2 is in its pre-formed curved shape when the antenna 2 projects from the portable telephone body 1. On the other hand, when the antenna 2 is accommodated in the portable telephone body 1, as shown in Fig. 813, the antenna 2 is inserted into a straight tube 30 disposed in interior of the body 1, thus being accommodated in the body 1. Also, the antenna 2 of the portable telephone shown in Fig. 7 is accommodated in the body 1 in the same manner.
