It is equipped with a microphone and speaker for enabling the above, a handset that fits the ear and mouth and has good acoustic coupling, and is configured as a very easy-to-use telephone. Generally, the key telephone C0 is installed in a fixed place such as a desk and used when it is in such a fixed position, and when it is separated from the fixed position, it cannot be taken out and used. do not do. The mobile phone D0 has basic functions such as a calling function, a receiving function, and a call function equivalent to a single phone, and is a mobile phone used when leaving a fixed position. The mobile phone D0 plays an auxiliary role to the button phone C0 and is premised on being used during movement, and sacrifices ease of use or comfort for downsizing. In this type of key telephone device, a convenient button telephone C0 is used at a fixed position, and a portable telephone D0 is used when leaving the fixed position to achieve a call regardless of location and time. However, it is not convenient to prepare two types of telephones and use them properly according to the purpose.

In order to solve this, there is a conventional usage mode of a button telephone device as shown in the system configuration diagram of FIG. In FIG. 15, the portable telephone D0 is connected via the wireless base station B1 that is wire-connected to the main device A1 of the button telephone device.

With such a configuration, the portable telephone E used at the fixed position
0 can be taken out to the destination as it is, and in that case, since it is connected to the main device A1 via the radio base station B1 or B2, it is not necessary to properly use the telephone depending on the purpose of use.
Further, there is an advantage that the cordless telephone C0 shown in FIG. 14 can be made cordless, leading to labor saving in wiring work. However, since the mobile phone E0 selects various functions in addition to the normal dial keys, a large number of function keys are required and the size becomes large. This is a fatal drawback for a mobile phone, which requires miniaturization and weight reduction. Therefore, the portable telephone E0 is miniaturized by reducing the dial keys, the function keys, and the display screen of the LCD. However, by realizing the downsizing, it is difficult to operate a small key, it is difficult to identify the display screen due to the small LCD, and by further reducing the shape, the transmitter and the receiver can be heard. You will not be able to make comfortable calls because you will not contact your mouth in the optimal state. Also, considering the situation of using the telephone, it is considered that the opportunity to use the telephone at the fixed position occupies most of the time, and the case where the telephone is taken out and used at the destination is very small.
Nevertheless, the portable telephone E0 must be downsized as a telephone that attaches importance to the function as a mobile device, and cannot perform a multifunctional operation like the button telephone C0 shown in FIG. 14, so that it is frequently used. The phone becomes inconvenient to use in a fixed position.

When the mounting signal 98 is "L" and not mounted, the power key signal 90 is output as the power key valid signal 90a. Also,
Power key signal 9 when the mounting signal 98 is "H"
All 0 inputs are invalidated, and the power key valid signal 90a is not output. Reference numeral 81 is a power supply control signal generation circuit, which outputs a power supply control signal 92 when either the power supply key valid signal 90a or the forced power-on signal 91 is input. 8
Reference numeral 2 denotes a closing time determination circuit, which removes chattering and the like included in the power supply control signal 92.
The charging time of 2 is measured, and when a predetermined time (for example, 1 second) or more has elapsed, a charging valid signal 93 is output. Reference numeral 83 denotes a release time determination circuit, which measures the release time (for example, 1 second) of the power supply control signal 92 from the end of pressing the power key 16 and outputs a release valid signal 94 when a predetermined time or more has elapsed. Reference numeral 84 is an identification signal generating circuit, which is a power key 16
An identification signal 95 for identifying whether the operation of turning on or off the power is generated. The identification signal 95 is set by the release valid signal 94. Reference numeral 85 denotes a hold signal generation circuit, which sets the power hold signal 96 by the turn-on valid signal 93 and clears the power hold signal 96 by the restoration signal 97. 86 is a restoration signal generating circuit, which is an identification signal 95.
When the closing valid signal 93 is input in the state where is set, the recovery signal 97 is generated. Reference numeral 87 denotes a compulsory permission / inhibition determination circuit, which does not output the forced power-on signal 91 when the power supply holding signal 96 is already set, and outputs the mounting signal 98 when the power supply holding signal 96 is cleared. Output as. 88 is a power supply switch,
Power is supplied while the power key signal 90 is being pressed and the power holding signal 96 is in the set state, and power supply is stopped when the power holding signal 96 is cleared.

12 and 13 are time charts for explaining the operation of the power supply controller 36. FIG. 12 shows the operation of turning on / off the power by pressing the power key 16 of the portable device 10, and FIG. 13 shows the operation of turning on / off the power of the portable device 10 when it is attached to the input / output auxiliary device 20. Is shown.

First, the operation of the power supply controller 36 will be described with reference to FIG. When the power key 16 is pressed, the power key signal 90 becomes "H" and is input to the power key determination circuit 80. At this time, since the mounting signal 98 is "L", the power key valid signal 90a is output and the power supply switch 88 is turned on. At the same time, the turn-on time determination circuit 82 starts measuring the turn-on time of the power key signal 90, and the "H" state of the power key valid signal 90a remains for a predetermined time (t ₁ : eg 1
When it continues for more than a second), the closing valid signal 93 is output. When the closing valid signal 93 is output, the power holding signal 96 is set to "H" in the holding signal generating circuit 85. After that, when the pressing of the power key 16 is released, the power key signal 90 becomes “L”, but the power supply signal 96 is kept at “H”, so that the power supply is maintained. At the same time, the release time determination circuit 83 starts measurement of the power key release time, and outputs the release valid signal 94 when the "L" state of the power key valid signal 90a continues for a predetermined time t ₂ (for example, 1 second) or longer. . When the release enable signal 94 is output,
The identification signal generating circuit 84 sets the identification signal 95,
It is stored that the next power key signal 90 is power off. Next, when the power key 16 is pressed and the power key signal 90 is generated, the power key valid signal 90a is generated in the same manner as above, the closing time t ₁ is measured, and when the closing valid signal 93 is output, the recovery signal The restoration signal 97 is created in the creation circuit 86, the power supply holding signal 96 is cleared in the holding signal creation circuit 85, and thereafter, the power supply key signal 90 becomes “L” and, at the same time, the power supply switch 88 stops the power supply. Power on / off is indicated by turning on / off the LED of the power key.

Next, referring to FIG. 13, a power-on / off operation when the portable device 10 is attached to the input / output auxiliary device 20 in a power-off state will be described. When the portable device 10 is attached to the accommodation portion 27a of the input / output auxiliary device 20, the attachment signal 98 becomes "H". In this case, since the power supply holding signal 96 has been cleared at this point, the compulsory availability determination circuit 87 outputs the mounting signal 98 as it is as the compulsory power-on signal 91. At the same time, the power-on time determination circuit 82 measures the power-on time t ₁ similarly to the power-on by pressing the power key 16, and when the power-on valid signal 93 is output, the power-holding signal 96 is set at that time. After that, the power supply switch 88 maintains the energized state.
Further, when the power holding signal 96 is set, the forced power-on signal 91 becomes "L", and the release valid signal 94 is output from the release time determination circuit 83 and the identification signal 95 is set after t ₂ as in the above. . Even if the power key 16 of the portable device 10 is erroneously pressed in this state, the power key determination circuit 8
Since the power key valid signal 90a is not output due to 0,
It does not affect the power control operation. Further, when the portable device 10 is pulled out from the housing portion 27a of the input / output auxiliary device 20, the mounting signal 98 becomes "L", but the power key signal 90 and the forced power-on signal 91 are not generated, so that the power control operation is performed. There is no change and the power supply continues. After that, portable device 1
When the power key 0 of 0 is pressed, the power supply is stopped by the power off operation of the portable device 10 as in FIG.

In addition to the case described with reference to FIG. 13, the portable device 10 in the power-on state is replaced with the input / output auxiliary device 20.
There is a case where it is attached to the accommodation portion 27a. In this case, when the mounting signal 98 becomes "H", the power holding signal 9
Since 6 has been set, the forced power-on signal 91 is not output and no change occurs in the power supply control operation. By configuring the power control unit 37 in this way, the power supply is not affected at all when the portable device 10 is mounted in the power-on state, and the power is forcibly turned on when the portable device 10 is mounted in the power-off state. I / O auxiliary device 20
When connected to the portable device 10 in any state
Can be turned on. Also, the portable device 1
When 0 is pulled out from the accommodating portion 27a of the input / output auxiliary device 20, the power-on state can be maintained. Therefore, even if the portable device 10 is detached or attached during a call, the power supply state does not change, and the control unit 33 can determine the presence or absence of the attachment by the attachment signal 98 and switch the operation.
