Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to telephones.

[0002]

2. Description of the Related Art FIG. 6 shows an example of a conventional portable radio telephone. In FIG. 6, reference numeral 1 is a housing of the telephone. A reception section 1R and a transmission section 1T are formed on the upper and lower parts of the front surface of the housing 1, respectively. This earpiece 1
A speaker 2 and a microphone 3 are arranged corresponding to the R and the transmitter 1T, respectively.

At the center of the front surface of the housing 1, a display 4 and a keyboard 5 which are composed of a liquid crystal display device or the like and which display a dialed telephone number and the like are arranged. In the keyboard 5, 5A is a ten-key used for dialing or the like, 5B is a send key for starting a call, 5C is an end key for ending a call, and 5D is a power key for turning power on and off.

An antenna 6 is attached to the upper end of the housing 1.

[0005]

In such a telephone, if the distance between the transmitter section 1T and the receiver section 1R is shortened in order to reduce the size, the position of the microphone 3 becomes far from the human mouth, and the clarity is improved. There is a disadvantage that it decreases.

Further, it is troublesome to search for the send key 5B because the call is started when an incoming call is received, and at the same time, it is troublesome to search for the end key 5C to end the call.

In addition, from the viewpoint of battery life, a light for illumination (not shown) is usually turned off, so it is necessary to turn on the light at the beginning of night use, which is troublesome. .

Further, since the send key 5B and the like are always exposed, there is a disadvantage that they are apt to be pressed by mistake.

In view of the above points, the present invention has an object to reduce the size without any inconvenience and to improve the usability for the user.

[0010]

As shown in, for example, FIGS. 1 to 5, the telephone of the present invention has a transmitter 1T or a receiver 1R attached to the main body 1 so as to be openable and closable, and is used in an open state during a call. The control means for controlling the illuminating means 14 for illuminating the vicinity of the keyboard 5 based on the output signal of the switch and the detection means 12, for example, the detection means for detecting the open / closed state of the transmitter 1T or the receiver 1R. And with.

[0011]

In the present invention, since the transmitter unit 1T or the receiver unit 1R is used in an open state during use, the transmitter unit 1T is used.
Even if the distance between the receiver and the receiver 1R is shortened, the distance becomes sufficient during a call, and the position of the microphone 3 can be brought close to the mouth of a human.

Illuminating means 1 for illuminating the vicinity of the keyboard 5 according to the open / close state of the transmitter 1T or the receiver 1R.
4 is controlled. Therefore, since the vicinity of the keyboard 5 is illuminated by the illumination means 14 when opened, it is convenient to use in a relatively dark place such as at night or in a car.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the telephone of the present invention will be described below with reference to FIGS. 1 to 5, those parts corresponding to those in FIG. 6 are designated by the same reference numerals, and a detailed description thereof will be omitted.

In this example, the transmitter 1T is attached to the main body of the housing 1 so as to be openable and closable around a shaft 11. Then, during a call, as shown in FIG.
T is opened and used. Further, as shown in FIG. 1, when the transmitter 1T is closed, the transmitter 1T covers the send key 5B, the end key 5C, and the power key 5D so as not to be exposed to the outside.

Further, in this example, as shown in FIG. 3, a lamp 14 for illuminating the vicinity of the keyboard 5 is provided at a predetermined position below the earpiece 1R. In FIG. 3, reference numeral 15 is a diffusion lens.

In FIGS. 4 and 5, reference numeral 12 is a switch which constitutes a detecting means for detecting the open / closed state of the transmitter 1T. As shown in FIG. 4, the switch 12 is in an off state without being pressed by the protrusion 13 when the transmitter 1T is closed, while the transmitter 12 is closed as shown in FIG. In the opened state, the protrusion 13 presses it to turn it on. And this switch 1
2 is connected to a system controller (not shown) having a microcomputer, and the operating state is controlled as shown in Table 1 according to the opening / closing of the transmitter 1T.

[0017]

[Table 1]

That is, at the time of an incoming call, when the transmitter 1T changes from the closed state to the open state, the call is started. Further, when the call is made from the open state to the closed state during the call, the call is ended. Further, at the time of waiting for an incoming call (idling), the lamp 14 is turned on when the transmitter 1T is changed from the closed state to the opened state, so that the vicinity of the keyboard 5 can be illuminated. On the contrary, the lamp 14 is turned on. Turned off.

This example is configured as described above, and the transmitter 1T
Is attached to the main body of the housing 1 so as to be openable and closable, and is used in an open state during a call. Therefore, even if the distance between the transmitter 1T and the receiver 1R is shortened, the call can be reduced. Sometimes the distance is sufficient, the microphone 3 can be brought close to the human mouth, and the inconvenience of lowering the clarity is eliminated.

When the transmitter 1T is opened during an incoming call, the call is started, when the transmitter 1T is closed during a call, the call is terminated, and when the incoming call is waited, the transmitter 1T is closed. When the 1T is opened or closed, the lamp 14 for illumination is turned on or off, respectively, which has the advantage of reducing the user's operation time, and the transmitter 1T is opened and put into use. At this time, the lamp 14 for illuminating the vicinity of the keyboard 5 is turned on, which is convenient for use in a relatively dark place such as at night or in a car. Further, when the transmitter 1T is closed, the send key 5B, the end key 5C, and the power key 5D are covered so as not to be exposed to the outside, so that an erroneous operation such as accidental pressing can be reduced. it can.

In the above embodiment, the transmitter 1T
Is openable and closable, but the transmitter 1R may be openable and closable. Further, in the above-mentioned embodiment, the opening / closing of the transmitter 1T is detected by turning on / off the switch 12, but the detecting means is not limited to this, and may be detected optically or magnetically, for example. You may do so.

Further, in the above-mentioned embodiment, the present invention is applied to a portable radio telephone, but it goes without saying that the present invention can be applied to a wired telephone as well.

[0023]

According to the invention described above, the transmitter or the receiver can be opened and closed with respect to the main body so that it can be used in an open state during a call, and the operating state can be changed depending on the opening and closing. Since it is controlled, it can be miniaturized without any inconvenience, and when it is opened and used, the vicinity of the keyboard is illuminated and it is convenient to use at night, in a relatively dark place such as in a car, The usability for the user can be improved.
