Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a radio telephone, and more particularly to a compact portable radio telephone that can be compressed into a small size and stored in a pocket, handbag, etc. when carried.

(Prior Art) In recent years, with technological advances in telecommunications and the like, portable wireless telephones equipped with various convenient functions have been commercialized. Portable radio telephones have been made smaller and more compact so that they can be easily stored in pockets, handbags, etc. when carried. FIG. 2 is a perspective view showing an example of the configuration of such a conventional portable radio telephone. In the figure, an antenna (antenna terminal) 11 for transmitting and receiving radio signals is provided on the top surface of a radio telephone main body 10 having a substantially rectangular parallelepiped shape.
is installed. Further, on the front part of the telephone main body 10, a receiver 12 and a transmitter 13 are provided in accordance with the positional relationship between the ears and mouth of the person using the radio telephone, and a push button dial is located in the center between these. 6 and a display section 5 for displaying the dial and the like.

The total length of the portable radio telephone constructed in this way is a', and if the antenna 11 is removed, the telephone main body 10
However, if the antenna 11 is removed, standby reception becomes impossible. In other words, conventional portable radio telephones require a minimum total length of a' to enable standby reception.

(Problems to be Solved by the Invention) However, the portable radio telephone having the above configuration has the following problems.

As shown in Fig. 2, the radio telephone always has a total length a' regardless of whether it is being carried or not, and this means that the distance between the receiver 12 and the transmitter 13 is similar to that of the human ear. Since this is determined by the positional relationship with the mouth and the antenna 11 is also fixed, the overall length had to be "a'". As a result, especially when carried, the radio telephone cannot be easily stored in a pocket, handbag, etc., and storage space is limited. For example, when carried in a briefcase or the like, there were many disadvantages such as decreased sensitivity. As described above, the above-mentioned wireless telephone cannot be said to have very good portable functions.

Furthermore, since the display section 5 and pushbutton dial section 6 provided on the front of the telephone main body 10 are exposed even when the phone is not in use, they are susceptible to shock and damage from the outside world, and as a result, the dials may be damaged due to external factors. There was a risk of malfunction.

Therefore, the present invention solves these conventional problems and creates a compact mobile phone with excellent telescoping functions that can be easily stored in a pocket or handbag by reducing the overall length when carried. The purpose is to provide wireless telephones.

(Means for Solving the Problems) In order to solve the problems of the prior art, the present invention configures a small portable radio telephone as follows.

The above-mentioned small portable radio telephone includes a radio telephone main body 1 comprising either a receiver 4 or a transmitter 7 and a radio telephone function section electrically connected to an antenna terminal 3 for transmitting and receiving radio signals; It is comprised of a housing case 2 which includes the other of the handset 4 and the transmitter 7 of the telephone main body 1 and movably accommodates the radio telephone main body 1 through an opening, and when in use,
The distance between the receiver 4 and the transmitter 7 can be set to a positional relationship suitable for operation, and the wireless telephone main body 1 can be housed in the housing case 2 when carried. The entire length can be expanded and contracted.

In a preferred embodiment of the present invention, the wireless telephone main body 1 is electrically connected to the wireless telephone function section. It is equipped with operating sections 5 and 6 for operating the radio telephone, and the operating sections 5 and 6 can be stored in the housing case 2 when carried.

(Function) According to the present invention, since the small portable radio telephone is constructed as described above, the function is as follows.

The above-mentioned small portable radio telephone has either a handset or a transmitter distributed between the main body of the radio telephone and the housing case, so that when it is normally carried, the main body of the radio telephone is housed in the housing case and compressed. Ru. Therefore, it can be easily stored in a pocket, handbag, etc. For example, if a pushbutton dial or display section is provided on the surface of the main body of the radio telephone, these are housed in a housing case and protected from the outside world.

Furthermore, when making a call, the entire length of the radio telephone is extended by moving the main body of the radio telephone from the accommodation case, and the distance between the handset and transmitter provided on each radio telephone main body and the accommodation case is adjusted depending on the operation. The positional relationship is suitable (for example, according to the distance between the user's ear and mouth).

As described above, according to the present invention, the small portable radio telephone can be expanded and contracted as required, thereby solving the problems of the prior art.

(Embodiment) An embodiment of the present invention is characterized in that when carried, the wireless telephone is compressed into a small size so that it can be stored in a pocket or handbag, and when used (for talking), it is expanded to make it easier to use. This figure shows a small portable radio telephone.

Hereinafter, a wireless telephone according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2. FIG. 1a is a perspective view showing a compact radio telephone when it is portable (including standby and reception), and FIG. 1b is a perspective view showing the radio telephone when it is extended when making a call. In FIGS. 1a and 1b, the same reference numerals are given to the same components as those in FIG. 2 used in the conventional explanation.

The small portable radio telephone according to this embodiment is comprised of a radio telephone main body 1 (hereinafter abbreviated as main body 1) and a housing case 2, as shown in FIGS. 1a and 1b.
The main body 1 has a substantially rectangular parallelepiped shape with a protrusion C having a length c formed on the upper part, a telescoping antenna 3 having a length b on the upper surface, and a receiver 4 in front of the protrusion C. A display part 5 and a pushbutton dial part 6 are mounted in the recessed part of the lower part of the protruding part C, and a radio telephone function part electrically connected to the antenna 3, display part 5 and pushbutton dial part 6 is arranged inside thereof. The total length thereof is shorter than the total length a' of the conventional portable radio telephone shown in FIG. This is because the transmitter 7 has been removed from the main body 1.

The storage case 2 is a rectangular parallelepiped-shaped container with one side open and a length d in order to store the main body 1,
A transmitter 7 is provided inside and below.

Normally, when carrying, the main body 1 is mostly stored through the opening of the storage case 2 as shown in FIG. , the receiver 4 is exposed from the housing case 2. In this state, the receiver 4 and the transmitter 7 do not need to be kept at a distance from the user's ear and mouth since the receiver is generally in standby reception mode. Therefore, the wireless telephone has a total length of “a”.
(=b+c+d)<a'" and is compressed into an extremely small size. Also, the display section 5 and pushbutton dial section 6 provided on the front of the main body 1 are housed in the housing case, so they are protected from the outside world. As a result, malfunction of the push button due to external causes can be prevented.

Next, when there is an incoming call (this can be notified by an alert sound, for example) or when you want to make a call yourself, press the pop-up button 8 provided on the side of the storage case 2, for example. As shown in Figure 1b, the main body 1 is slowly protruded by c',
The display section 5 and push button dial section 6 are exposed from the housing case 2. In conjunction with this, the antenna 3 is also slowly protruded from the main body 1 by b', making the total length of the antenna 3 "b+b'". Such a mechanism for protruding the main body 1 and the antenna 3 is as follows.
It can be configured by various well-known means. Alternatively, it is also possible to perform this protrusion manually. Furthermore, holding of the protruding main body 1 can be achieved, for example, by providing a flexible claw on the side surface of the main body 1 that engages with a groove provided on the inner surface of the storage case 2. In this way, when the main body 1 and the antenna 3 are made to protrude from the housing case by a length "c'+b'",
The total length of the wireless telephone is a′ (=b
+b'+c+c'+d), and the receiver 4 and the transmitter 7 have the same positional relationship as the ear and mouth of the user. Therefore, using the pushbutton dial section 6, the user confirms the dialing on the display section 5 and starts a call.

Incidentally, since the main body 1 protrudes from the storage case 2 during a call, the storage case 2 is almost empty, and this empty space can be used for the following purposes.

1. When making a call, the main body 1 is operated, so it can be used for heat dissipation.

2. When the wireless telephone is not carried around, for example in the office, at home, in a car, etc., a battery can be added to enable long-term use. Additionally, a cassette charger (AC charger from the mains supply or DC charger from the car's cigarette socket) can be inserted to allow charging or floating use of the battery.

As described above in detail, the small mobile radio telephone according to the present embodiment has a receiver 4 in the main body 1 and a transmitter 7 in the housing case 2, respectively, and by dispersing the functions, the entire length of the telephone when carried is “a
(<a')'', and when making a call, it can be expanded so that the receiver 4 and the transmitter 7 are in the exact positional relationship between the ear and the mouth.

(Effects of the invention) As explained above in detail, according to the invention,
When carried, the small portable radio telephone can be compressed and miniaturized by storing the main body of the radio telephone in a housing case, thereby making it easy to store in a pocket, handbag, or the like. Also, when making a call, by protruding the wireless telephone body from the housing case,
The overall length of the radiotelephone is extended, so that the distance between the handset and the handset can be adjusted to suit the ear-to-mouth relationship of the user.

Furthermore, during a call, the main body of the wireless telephone protrudes from the housing case, so that the housing case becomes almost empty, and this empty space can be used for the following purposes.

1. During a call, the wireless telephone itself is operated, so it can be used for heat dissipation.

2. When the said small portable radio telephone is not carried,
For example, when using the device in an office, home, car, etc., a battery can be added to enable long-term use. Furthermore, to enable charging or floating use of the battery, a cassette charger (AC charger from commercial power supply or DC charger from the car's cigarette socket) is required.
can be inserted.

As described above, according to the present invention, it is possible to provide a small portable radio telephone having excellent portable functions.
