DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone,
In particular, it relates to the structure of a mobile phone.

[0002]

2. Description of the Related Art In recent years, the number of users of mobile phones has been increasing in accordance with changes in the social environment and business forms. In addition to the enhancement of functions, the use of mobile phones has become more compact and lighter. It is planned. For example, Japanese Patent Application Laid-Open
Japanese Patent No. 247,734 discloses a main unit in which a liquid crystal display unit is arranged on an inner surface, a receiving unit connected to one end of the main unit by a hinge mechanism and folded only in the inner surface direction, and the other of the main unit. A foldable mobile phone having a transmitting unit that is connected to an end by a hinge mechanism and that can be folded only in the inner surface direction is shown.

[0003]

In the above-mentioned conventional portable telephone, there is a physical limit to the miniaturization of each unit, including operational considerations, and it is difficult to reduce the size of each unit. In order to reduce the size, the receiving unit and the transmitting unit are foldably divided.
Due to this folding structure of the mobile phone, most of the liquid crystal display unit is hidden when folded, and it is not possible to check the display of the entire display unit. There is a problem that it does not become.

[0004] It is an object of the present invention to provide a portable telephone which realizes miniaturization by using an expansion / contraction structure without using a folding structure, and which has improved convenience so that the entire display unit can be checked during standby.

[0005]

A portable telephone according to the present invention comprises:
A structure in which a main body of a mobile phone is divided into a first main body and a second main body, the second main body is pushed into and accommodated in the first main body during standby, and the pushed-in second main body is pulled out and used during a call. The first main body includes a display unit for displaying various information.

A portable telephone according to the present invention comprises a hollow portion having a hollow inner surface, an open bottom surface, and a protrusion for projecting a tip of an antenna from the upper surface, and first stoppers provided at lower portions on both sides of the inner surface.
A first main body having a receiver and a display for displaying various information; a second stopper coupled to the first stopper on upper and lower sides on both outer sides of the outer surface; a transmitter and various operation inputs; A main unit having an operation unit comprising buttons and keys for performing the operation, a radio unit for transmitting and receiving radio signals, and a control unit for controlling each unit of the telephone, and slidably housed in the cavity of the first main unit. And;

The first and second stoppers are formed using magnets, and the first main body has projections on both sides of an inner surface for engaging with the second main body. The second main body may have a structure having grooves on both sides of the outer surface for engaging with the protrusions.

According to the present invention, the second main unit is housed in the first main unit during normal standby, and is pulled out and used during a call. This not only shortens the overall length of the mobile phone during standby and makes it possible to reduce the size of the mobile phone, but also eliminates the need to open the main unit when switching to a call. The display can be checked.

[0009]

Next, embodiments of the present invention will be described with reference to the drawings.

(A) is a perspective view showing a state of the mobile phone according to the embodiment of the present invention in a standby state, and (b) is a perspective view showing a part of the internal structure of (a).

Referring to FIGS. 1 and 2, the portable telephone comprises a main body 1 and a main body 2. The main body 1 has a hollow portion 9 with a hollow inner surface and an open bottom surface, and a hole 9 for projecting the tip of the antenna 3 from the upper surface. A stopper 10 is provided at the lower part on both sides of the inner surface, and a receiver 4 and a display unit 5 for displaying various information are provided.
The main body 2 is provided with stoppers 8 and 11 to be coupled to a stopper 10 of the main body 1 on upper and lower sides on both sides of the outer surface, a transmitter 7, an operation unit 6 including buttons and keys for performing various operation inputs, and a radio signal. Radio section for transmitting and receiving (not shown)
And a control unit (not shown) for controlling each part of the telephone.

The stopper is constructed by using a magnet, and when waiting, as shown in FIG. 2B, the stopper 10 and the stopper 11 are connected and fixed. On the other hand, as shown in FIG. The stopper 10 and the stopper 8 are connected and fixed.

FIG. 3A is a diagram showing the arrangement of signal lines inside the main body 1 of FIG. 1A. The connection of the signal line to the display unit 5 is performed using a flat cable 12 via a connection point 13 between the display unit and the flat cable, and a signal line from a connection point 14 between the flat cable and the printed circuit board to a lower part 15 of the printed circuit board. Is a printed circuit board 16.

FIG. 3B is a diagram showing the arrangement of signal lines when the main body 1 is viewed from below, and FIG. 3C is a diagram showing the arrangement of signal lines.
FIG. 5 is a diagram showing a state of wiring on a printed circuit board in FIG.
