2 is a predetermined time (for example, 1
(Every 0 mSec) to detect the state of charge. When the slave unit 2 is placed on the master unit 1 and is in a charged state, the charge state detection unit 22 checks whether or not the charge state is already detected (STEP 1). The charging terminal 1A of the master unit 1 , 1B, and 1C contact charging terminals 2A, 2B, and 2C of slave unit 2, respectively. When the charging terminals 1B and 2B come into contact with each other, a charging current is supplied from the charging current supply means 11 of the parent device 1 to the battery 21 of the child device 2, and the battery 21 of the child device 2 is charged. Also, charging terminals 1A and 2A
, The logic level of the charging terminal 2A of the slave unit 2 changes from "1" to "0" (STEP

When the state of the logical level "0" continuously overflows for a certain period of time T0 set by the timer 24, it is detected that the slave unit 2 has been charged (STEP 4). The timer 24 is used to prevent the detection from becoming unstable due to chattering when the charging terminals 1A to 1C and 2A to 2C come and go, and the set value T0 is several tens mSec to 100
It is set to about mSec.

題点を有していた。However, in the above-described conventional configuration, a horizontal cordless telephone (FIG. 3) in which a portable unit is placed sideways for charging is premised, and such a horizontal cordless telephone is used. In the above, it is thought that it is unlikely that the slave unit will be inadvertently shaken due to external factors except when the user intentionally lifts the slave unit when the slave unit is in the charged state. The vertical cordless telephone (FIG. 4), which is charged by charging, is less stable than the horizontal cordless telephone (FIG. 3). In addition to lifting the machine, external factors such as the touch of the user's body and the location of the phone may fluctuate, causing the handset to wobble carelessly and incorrectly recognizing the charging status There is. For example, a function that allows you to talk immediately without pressing the call button when the phone goes from a charged state to a non-charged state during an incoming call, and ends the call when you go from a non-charged state to a charged state during a call Function works continuously,
In the end, there is a problem that a period during which a call cannot be received may occur.

When the child device 2 is placed on the parent device 1 to be charged, the charging terminals 1A (first terminal), 1B (second terminal), and 1C of the parent device 1 are connected to the child device 2 respectively.
Contact terminals 2A (third terminal), 2B (fourth terminal) and 2C. At this time, the charging state detecting means 22 does not detect charging within the time T0 (STEP
1). When the charging terminals 1B and 2B come into contact with each other, a charging current is supplied from the charging current supply means 11 of the master unit 1 to the battery 21 of the slave unit 2, and the battery 21 of the slave unit 2 is charged. When the charging terminals 1A and 2A come into contact with each other, the logic level of the charging terminal 2A of the slave unit 2 changes from "1" to "0" (STEP 2).

4 starts to be counted (STEP 3), and when the state of the logic level “0” continuously overflows for a certain period of time T0 defined by the timer 24, it is detected that the slave unit 2 is in the charged state. (Step 4). The control unit 23 of the slave unit 2 determines that the charging state detection unit 22 has the timer 2
When it is detected from the non-charged state to the charged state due to the overflow of 4, the control when the non-charged state is changed to the charged state, for example, a function of terminating the talk state when the slave unit 2 is in the talk state. Perform control.

The logic level of the terminal 2A changes from "0" to "1" (STEP 5). When the logic level of the charging terminal 2A changes from the state of “0”, that is, the charging state, to the state of the logic level “1”, that is, the non-charging state, the charging state detecting means 22 of the child device 2 counts the second timer 25. Is started (STEP 6), and when the state of the logic level "1" continuously overflows for a certain period of time T1 defined by the timer 25, it is detected that the slave unit 2 is in the non-charged state (step 6).

〜10倍程度(数百mSec)とする。Here, if the set value T of the timer 25 is
1 is in the charging state, the handset 2 is shaky, and the charging terminals 1A and 2A
Is set to be shorter than the time when the mobile phone is separated, and when the mobile phone 2 is lifted during the incoming call, that is, when the mobile phone is switched from the charged state to the non-charged state, the mobile phone 2 does not need to press the talk button. It is assumed that the mobile phone has a function of making a call and a function of terminating the call when the mobile phone changes from a non-charged state to a charged state during the call. If the handset 2 fluctuates during charging and an incoming call, first, control is performed in a case where the handset is changed from a charged state to a non-charged state, that is, a function that allows a call to be made immediately without pressing a talk button is activated. Is in a call state. However, since the handset 2 immediately returns to the charged state, the control when the charged state is changed from the non-charged state to the charged state during the call, that is, the function of terminating the call works, and the call cannot be eventually picked up. That is, a defective period will occur.
Therefore, if the set value of the timer 25 is set to a value T1 longer than the time that the charging terminals 1A and 2A are separated due to the wobble of the slave unit, the above-described problem can be solved, and the user can be sure. Control unit 2 only when handset 2 is lifted
Numeral 3 controls when the state changes from the charged state to the non-charged state. This time T1 is about three times larger than T0 of the previous timer 24.
Approximately to 10 times (several hundred mSec).

のがある。As described above, the cordless telephone according to the present invention has a charge state after the first set value of the first timer corresponding to chattering or the like when the slave unit is connected to the master unit. Is detected, and when the slave unit is disconnected from the master unit, after the time of the second set value of the second timer corresponding to the temporary disconnection due to an inadvertent external factor, By configuring to detect that the charging status has ended, in addition to the user lifting the child device when the vertical type child device is in the charging state, external factors such as the user's If the handset is inadvertently shaken due to touching the body or the location of the phone, etc., it may be incorrectly recognized as being in a charged state. A function that allows you to call immediately without pressing the call button Next, the function of terminating the call when the state is changed from the non-charged state to the charged state during the call works continuously, thereby preventing a problem that a period during which a call cannot be received may be eventually generated. The practical effects are significant.
