The operation of the portable telephone in the embodiment will be explained below.
When the portable telephone main body 100 and the operating unit 200 are combined, the power switch 110 of the portable telephone main body 100 is operated to switch on or off the power of the portable telephone main body 100. In this case, data is sent and received between the portable telephone main body 100 and the operating unit 200 with the connecting terminal 111 of the portable telephone main body 100 and the connecting terminal 208 of the operating unit 200 connected with each other.
On the other hand, when the portable telephone main body 100 and the operating unit 200 are separated from each other, the power switch 110 of the portable telephone main body 100 and the power switch 207 of the operating unit 200 are operated to switch on or off the power of the portable telephone main body 100 and the operating unit 200, respectively. In this case, data is sent and received between the portable telephone main body 100 and the operating unit 200 by transmitting and receiving an infrared signal between the transmitting-receiving section 108 of the portable telephone main body 100 and the transmitting-receiving section 205 of the operating unit 200, where both the transmitting-receiving sections 108 and 205 are preferably composed of a light-emitting element such as an infrared lightemitting diode and a light-receiving element such as a phototransistor.
To make a call from the portable telephone, the portable telephone's user inputs a telephone number of a called party by using the keypad or a contraction key of the operating unit 200 and then pushes down the calling key. By pushing down the calling key, a call signal and a telephone number of the called party are transmitted from the transmitting-receiving section 205 of the operating unit 200 to the transmitting-receiving section 108 of the portable telephone main body 100. Thereby, the portable telephone main body 100 gets into the calling state, setting a telephone circuit though radio to a base station to allow a conversation with the called party.
On the other hand, when the portable telephone receives a call, the portable telephone's user pushes down the calling key of the operating unit 200, thereby a call-reaching response signal is transmitted from the transmitting-receiving section 205 of the operating unit 200 to the transmitting-receiving section 108 of the portable telephone main body 100. Thereby, the portable telephone main body 100 responds to a call signal from a base station, setting a telephone circuit though radio to the base station to allow a conversation with a caller.
To finish the communication, the portable telephone's user pushes down the ring-off key of the operating unit 200, thereby a ring-off signal is transmitted from the transmitting-receiving section 205 of the operating unit 200 to the transmittingreceiving section 108 of the portable telephone main body lug0.
Thereby, the portable telephone main body 100 conducts a ring-off operation to break the radio telephone circuit to the base station.
A portable telephone in the second preferred embodiment will be explained in FIG.3, wherein like parts are indicated by like reference numerals as used in FIG.2. FIG.3 shows a state that an operating unit 200 is released from a portable telephone main body 100.
The portable telephone main body 100 is provided with a speaker 106 on the top and a microphone 107 on the bottom, which are disposed with an interval corresponding to an average distance between an ear and a mouth of man.
The operating unit 200 can be releasably mounted between the speaker 106 and the microphone 107. The operating unit 200 is provided with an input section 201 and a display 202. The input section 201 is composed of keys, for example, a calling key, a ring-off key and a keypad, by which a user operates the portable telephone. The display 202 is composed of a display unit such as a liquid crystal display, which displays data input from the input section 201 or data received from the portable telephone main body 100.
The operating unit 200 is provided with a transmittingreceiving section 205 on the upper side, where data is transmitted and received to and from the transmitting-receiving section 108 of the portable telephone main body 100. The transmitting-receiving section 205 is preferably composed of a light-emitting element such as an infrared light-emitting diode for transmitting a infrared signal and a light-receiving element such as a phototransistor for receiving a infrared signal.
Also, the operating unit 200 is provided with a connecting terminal 208(not shown) disposed at a position corresponding to a connecting terminal 111 on the back side.
The portable telephone main body 100 is provided with the transmitting-receiving section 108 and the connecting terminal 111 on the front side, where data is transmitted and received to and from the transmitting-receiving section 205 of the operating unit 200. The transmitting-receiving section 108 is preferably composed of a light-emitting element such as an infrared lightemitting diode for transmitting a infrared signal and a lightreceiving element such as a phototransistor for receiving a infrared signal.
In the second eniodiment, there are provided the two transmitting-receiving sections 108, 108. One is disposed at a position that corresponds to the transmitting-receiving section 205 when the operating unit 200 is mounted on the portable telephone main body 100. By this transmitting-receiving section 108, the transmission and reception of data between the portable telephone main body :00 and the operating unit 200 can be performed without using the connecting terminals 111, 208. The other is disposed on the top corner, whereby infrared rays from the operating unit 200 are easy to receive and the reach of the infrared rays can be therefore enlarged.
When the portable telephone's user wants to make a memo of some information such as a telephone number while talking on the telephone, he can operate the keys of the operating unit 200.
Thereby, the contents of the key operation can be stored in the memory 203 through CPU 204. At this time, the user can make a memo by using the operating unit 200 without keeping the portable telephone main body 100 away from his ear and mouth, i.e., without interrupting the talking since the operating unit 200 can be separated from the portable telephone main body 100.
Meanwhile, when the contents of the key operation are registered as a contraction dialling, the user can easily make a call by using the contraction dialling.
Optionally, the contents of the key operation can be stored in the memory 103 of the portable telephone main body 100 by transferring them through CPU 204, the transmitting-receiving section 205, the transmitting-receiving section 108 and CPU 10Q to the memory 103.
Though, in the above embodiments, the infrared communication is used between the transmitting-receiving sections 108 and 205, a low-power radio wave communication may be used therebetween.
When the operating unit 200 is mounted on the portable telephone main body 100, the power may be supplied from the portable telephone main body 100 to the operating unit 200 through the connecting terminals 111 and 208 through which data is usually transmitted and received.
Although the invention has been described with respect to specific embodiment for complete and clear disclosure, the appended claims are not to be thus limited but are to be construed as embodying all modification and alternative constructions that may be occurred to one skilled in the art which fairly fall within the basic teaching here is set forth.
