Abstract

PURPOSE:To improve the operability of a retractable antenna and to prevent the generation of its damage or loss. CONSTITUTION:This portable telephone set 5 is provided with a call switch 1 for switching the ON/OFF of a call start to an internal circuit part 10, a retractable antenna 3 for transmitting/receiving radio communication waves and a sliding mechanism part 2 for automatically moving the antenna 3 whose leading part 31 is stored in a casing 51 when the switch 1 is in the OFF state from the surface 52 of the casing 51 to the outside up to previously determined length while sliding it when the switch 1 is in the ON state.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile phone.

[0002]

2. Description of the Related Art A conventional mobile phone is a mobile phone 5a as shown in FIG. 3A, which has an antenna structure in which an antenna 6a is previously attached to the outside, or FIG.
The mobile phones 5b and 5c shown in (B) and (C) have an antenna structure for pulling up the antennas 6b and 6c during use.

As shown in FIG. 3 (B), the mobile phone 5b has a structure in which the tip of the antenna 6b is protruded to such an extent that it can be easily pulled up. As shown in FIG. 3 (C), the mobile phone 5c has an antenna. It has a structure in which a recess 8 is formed so that the tip of 6c can be stored, and the antenna 6c is stored therein.

[0004]

This conventional mobile phone has a structure in which the antenna 6a is attached to the outside in advance in the mobile phone 5a as shown in FIG. It is inconvenient to carry it in a bag, etc., for example, there is a problem that the antenna 6a is caught in other luggage and is difficult to take out, and there is a risk that it may be broken. Furthermore, it cannot be carried in a jacket pocket. There were problems such as leprosy.

Even if the antenna is detachable or has a structure such as a plug-in type or a screw-in type, it may be difficult to mount the antenna, or the antenna may be lost or the screw thread may be worn out so that the antenna may be easily removed. There was a problem that it would end up.

The mobile phone 5b shown in FIG.
3 has the same problems as the mobile phone 5a shown in FIG. 3A, and the mobile phone 5c shown in FIG. 3C has no problem with the mobile phones 5a and 5b, but the antenna 6
Since c is housed in the recess 8, there is a problem that it is difficult to pull out the tip of the antenna 5c.

[0007]

The mobile phone of the present invention comprises:
A call switch for turning on and off the start of a call to the internal circuit part, a retractable antenna for transmitting and receiving radio call radio waves, and a retractable antenna having a tip portion inside the housing when the call switch is off. And a slide mechanism section that automatically moves while sliding the surface of the housing from the surface of the housing to a predetermined length when the call switch is turned on.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 shows an embodiment of the present invention, (A) is a block diagram of this embodiment, and (B) is a perspective view of this embodiment.

1 (A) and 1 (B), a mobile telephone 5 according to the present embodiment has a call switch 1 for switching on / off of activation of a call to an internal circuit section 10 and transmission / reception of radio call radio waves. And the retractable antenna 3 whose tip 31 is inside the housing 51 when the call switch 1 is off, and the retractable antenna 3 which performs a predetermined length (2 to 3) from the housing surface 52 when the call switch 1 is on.
cm) and a slide mechanism section 2 for automatically moving while sliding to the outside.

Next, the operation of this embodiment will be described.

In the portable telephone 5 of this embodiment, the call switch 1 is in the off state in the standby state, so that the retractable antenna 3 is stored in the housing 51 as shown in FIG. 1 (B).

When the call switch 1 is turned on when the internal circuit section 10 emits a ringing tone when an incoming signal is detected, or when the call switch 1 is turned on at the time of making a call, the slide mechanism section is passed through the control line 4. Starts up on 2. Slide mechanism section 2
The retractable antenna 3 has the tip 31 of the housing surface 5
The retractable antenna 3 is automatically moved while being slid to the outside from 2 to a predetermined length (2 to 3 cm). After this movement is stopped, the retractable antenna 3 is moved to the housing 51 by pulling the tip 31.
Can be pulled from.

When the call switch 1 is turned off after the end of the call, the slide mechanism unit 2 is activated, the retractable antenna 3 is housed in the housing 51, and the tip end portion 31 is removed when the activation of the slide mechanism unit 2 is stopped. If pressed, the tip portion 31 is also stored in the housing 51, the tip portion 31 does not protrude from the housing surface 52, and the state shown in FIG. 1B is restored.

The mobile phone 5 in the state shown in FIG.
Since the retractable antenna 3 is stored in the housing 51, the retractable antenna 3 can be stored in a bag or the like.
Will not be damaged or lost.

[0016]

As described above, according to the present invention, the call switch for turning on / off the call to the internal circuit portion, the retractable antenna for transmitting / receiving the radio call radio wave, and the call switch for off are provided. In the state, the retractable antenna with the tip portion inside the housing is provided with a slide mechanism portion that automatically moves while sliding outward from the surface of the housing to a predetermined length when the call switch is on. Since the retractable antenna can be carried in the case when it is put in a bag or the like, it is possible to prevent the retractable antenna from being damaged.

Further, since the retractable antenna is inside the housing when the call is off, and automatically comes out on the surface of the housing when the call is on, the antenna is easy to use and can be prevented from being lost. There is an effect that can be done.
