Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone,
In particular, the present invention relates to a mobile phone having a structure in which a rod antenna can be stored in a housing. 2. Description of the Related Art FIGS. 2 (a) and 2 (b) are side views showing use states of first and second examples of a conventional portable telephone. [0003] The housing 1b of the portable telephone in FIG.
Is thinner than the housing 1a of the mobile phone shown in FIG. [0004] For example, in FIG. 2A, a rod-shaped antenna 2a is a part of a surface of a housing 1a of a portable telephone when the user uses the earpiece 3 with his / her ear in contact with the ear. First surface 6 with axis facing user's temporal
And the outer side thereof is stored substantially parallel to the second surface 7 opposed thereto. Therefore, when the rod-shaped antenna 2a is pulled out, the distance between the element 8 at the tip of the antenna 2a and the first and second surfaces 6 and 7 is substantially constant. In FIG. 2B, this interval is substantially constant. [0006] As the size of portable telephones has been reduced, it has become increasingly important to reduce the thickness of the housing in consideration of, for example, the ability to store in a pocket. On the other hand, as shown in FIG. 2, a rod-shaped antenna generally provided in a portable telephone is pulled out to the upper surface when the earpiece 3 is put on the ear, so that the first antenna shown in FIG.
As can be seen from the above example and the second example shown in FIG. 4B, the thinner the housing, the closer the element at the tip of the antenna is to the temporal region of the user. Since the head of a human body has a property of absorbing radio waves, the effect is more liable to be affected as the antenna element is closer to the head, and the actual antenna gain is reduced. Therefore, in the structure of the conventional portable telephone, the area in which the portable telephone can be used is reduced, or the line is cut off at the moment when the portable telephone receives an incoming call and touches the earpiece to the ear. There was a problem. A portable telephone according to the present invention comprises:
The features are as follows. That is, the portable telephone of the present invention has a receiver and
And the transmitter on the first side facing the user's temporal
Equipped and can be stored in the housing and pulled out from the upper surface
A mobile phone comprising a rod-shaped antenna on an upper surface of the housing.
Thus, with the tip portion pulled out of the housing,
A second surface opposing the first surface from the first surface to the outside of the first surface;
The rod-shaped antenna element, which is tilted in the direction of
It is characterized by having. Next, the present invention will be described with reference to the drawings. FIG. 1 is a side view showing an embodiment of the mobile phone of the present invention. The rod-shaped antenna 2 which can be stored in the housing 1 of the mobile phone has an upper surface 4 when the earpiece 3 is used with the earpiece in contact with the ear.
Attached to. When the rod-shaped antenna 2 is housed in the housing 1 as shown by a broken line, the rod-shaped antenna 2 is inclined with respect to the first surface 6 facing the user's temporal region and the second surface 7 facing the outside. When the rod-shaped antenna 2 is pulled out, the element 8 at the tip of the rod-shaped antenna 2 is attached so as to be away from the first surface 6 as shown by a solid line. That is, in this state of use, since the element 8 moves away from the temporal region of the user, a decrease in the gain of the antenna 2 due to the user's head can be suppressed. Note that a transmitting section 5 is provided below the housing 1. As described above, in the portable telephone according to the present invention, the stowable rod-shaped antenna is housed obliquely in the housing, and when it is pulled out, the element at the tip of the bar-shaped antenna is placed on the side of the user. Since the user is kept away from the head, the influence of radio wave absorption by the user's head is suppressed to a small extent, and a call can be made with the substantial gain of the antenna kept high. Therefore, there is an effect that the available area is expanded as compared with the conventional portable telephone.

Claims (1)

(57) [Claim 1] A receiving unit and a transmitting unit are provided on a first surface facing a temporal region of a user of a housing, and can be housed in the housing and can be housed from above. A mobile phone provided with a rod-shaped antenna to be pulled out on the upper surface of the housing, wherein the element at the tip of the rod-shaped antenna is in the first position in a state where the rod-shaped antenna is pulled out from the housing, before the element is pulled out . A mobile phone, which is away from the first surface in a direction from a surface outside the first surface to a second surface opposite to the first surface.
