A call request is transmitted from the transmission / reception unit 45.

<Operation of Embodiment>
The detailed operation of the telephone 100 having such a configuration will be described with the control unit 44 as an axis.
When the user is winding the band 30 around the arm while the main body 10 is mounted on the base 20, the attachment / detachment detection signal is “Low”. When the attachment / detachment detection signal is “Low”, the control unit 44 places the telephone 100 in a standby state.

  In the standby state, the control unit 44 can receive an incoming call from another person. When there is an incoming call, the transmission / reception unit 45 outputs a message to that effect to the control unit 44. Upon receiving the output, the control unit 44 instructs the incoming call notification circuit 48 to perform incoming call notification. In response to the instruction, the incoming call notification circuit 48 notifies the user that there is an incoming call. In response, the user removes the main body 10 from the base 20. At the time of this removal, the movable contact 46c constituting the contact mechanism 46a of the attachment / detachment detection unit 46 is released from being pushed up by the attachment / detachment detection protrusion 23 provided on the base 20, so that the contact of the contact mechanism 46a is closed. A signal “Hi” is output from the attachment / detachment detection signal circuit 46b.

  When the output signal of the attachment / detachment detection unit 46 becomes “Hi”, the control unit 44 causes the transmission / reception unit 45 to transmit an incoming call response to the called party. As a result, a line is established between the telephone 100 and the called party, and the telephone 100 enters a telephone conversation state. The user makes a call by placing the speaker 42 on the back surface of the main body 10 removed from the base 20 against the ear. When the call is finished and the user wears the main body 10 on the base 20, the output signal of the attachment / detachment detection unit 46 becomes “Low”. When the control unit 44 detects a change in the output signal of the attachment / detachment detection unit 46 to “Low”, the control unit 44 returns the telephone 100 to the standby state.

Next, a case where the user makes a call from the telephone 100 will be described.
The user removes the main body 10 from the base 20 when he / she wants to make a call with another person using the telephone 100. As a result, since the attachment / detachment detection signal becomes “Hi”, the control unit 44 enters a telephone number input waiting state. In this state, when the user operates the operation buttons 41 one by one and sequentially inputs each digit of the telephone number of the called party, a series of number recognition signals are sent from the number recognition unit 41a to the control unit 44. Based on the series of number recognition signals, the control unit 44 obtains the telephone number of the call destination and transmits a call request including the telephone number from the transmission / reception unit 45. In response to this call request, an incoming call is made to the other party, and when the other party sends an incoming call response, a line is established between the telephone 100 and the other party, and a call can be established between them. The user of the telephone 100 attaches the main body 10 to the base 20 when desiring to end the call. As a result, the output of the attachment / detachment detection unit 46 becomes “Low”, and the control unit 44 detecting this returns the telephone 100 to the standby state.
As described above, the control unit 44 inputs the input signal when the two conditions of completion of inputting the telephone number of the predetermined number of digits by the operation button 41 and the attachment / detachment detection signal “Hi” are satisfied. Since the call request including the received telephone number is transmitted from the transmission / reception unit 45, the telephone number of the other party to be called by the operation button 41 may be specified with the main body 10 mounted on the base 20. At this time, the control unit 44 transmits a call request from the transmission / reception unit 45 when the main body 10 is detached from the base 20.

  As described above, the telephone 100 according to the present embodiment performs an operation corresponding to an off-hook of a normal telephone by removing the main body 10 from the base 20, and corresponds to an on-hook of a normal telephone by being attached to the base 20.

Furthermore, the operation button 41 may be provided in the form of a knob on the side surface of the main body, such as a crown on a wristwatch, without being provided around the display unit 12. Further, instead of such mechanical telephone number designation, a mode in which a voice recognition circuit is provided in the main body 10 and the user designates the telephone number by voice may be used.

  Note that the telephone 100 according to the present embodiment is similar in appearance to a wristwatch or the like that has been conventionally worn on the wrist, so that even if integrated with them, the effect is not hindered. For example, if digital display time information or the like is displayed on the display unit 12, a function equivalent to a digital display wristwatch is provided to the user. In this case, the control unit 44 may perform control so that information about time or time is displayed on the display unit 12 only when the telephone 100 is in a standby state. Further, an analog display clock may be provided in the display unit. In this case, the display unit 12 does not need to be configured by an LCD or the like, and the display unit 12 is formed with a long hand, a short hand, a second hand, a dial, and the like similar to a normal analog wristwatch. In this way, since the display unit 12 always displays the clock, there is no difference in appearance from the wristwatch.
