Under the control of the control unit 23, 2 is a fixed time (for example, 1
It is activated every 0 mSec) to detect the state of charge. When the child device 2 is placed on the parent device 1 and enters the charging state, the charging state detection means 22 checks whether or not the current charging state has already been detected (STEP 1), and the charging terminal 1A of the parent device 1 is checked. , 1B and 1C are in contact with 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 to charge the battery 21 of the child device 2. Also, charging terminals 1A and 2A
By the contact with and, the logic level of the charging terminal 2A of the handset 2 changes from "1" to "0" (STEP

When the state of the logic level "0" continuously overflows for a certain time T0 set by the timer 24, it is detected that the handset 2 is in the charging state (STEP 4). The timer 24 is for preventing the detection from becoming unstable due to chattering when the charging terminals 1A to 1C and 2A to 2C come into contact with each other, and the set value T0 is several tens msec to 100 msec.
It is set to about mSec.

題点を有していた。However, the conventional configuration as described above is premised on the horizontal cordless telephone (FIG. 3) in which the cordless handset is placed horizontally for charging, and such a horizontal cordless telephone is used. In addition, it is considered that the handset does not wobble inadvertently due to external factors except that the user intentionally lifts the handset when the handset is in a charged state. As for the vertical cordless telephone (Fig. 4) that is charged by charging, the stability of the cordless handset is lower than that of the horizontal cordless telephone (Fig. 3). In addition to lifting the device, external factors such as touching the user's body or wobbling the place where the phone is installed may inadvertently wobble the handset and erroneously recognize the charging status. There is. For example, if you change from the charging state to the non-charging state while receiving an incoming call, you can immediately call without pressing the call button, and then end the call when you change from the non-charging state to the charging state during a call. Function to work continuously,
In the end, there was a problem that a period during which an incoming call could not be picked up might occur.

Here, the charging state detecting means 22 of the child device 2 determines that the charging terminal 2A is in the charging state when the logic level of the charging terminal 2A is "0" and is in the non-charging state when it is "1", and the normal charging terminal 2A is It is assumed to be at the logic level "1". Further, it is assumed that the charge level notification means 12 of the parent device 1 outputs a logic level "0".

変化する(STEP2)。Under the control of the control unit 23, the charge state detecting means 22 detects the charge state at regular time intervals as in the conventional example. When the slave unit 2 is placed on the master unit 1 and is in a charging state, the charging terminals 1A (first terminal), 1B (second terminal) and 1C of the master unit 1 are respectively the slave unit 2
Of the charging 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 base unit 1 to the battery 21 of the handset 2, and the battery 21 of the handset 2 is charged. Further, the contact between charging terminals 1A and 2A changes the logic level of charging terminal 2A of slave unit 2 from "1" to "0" (STEP2).

4 starts to be counted (STEP 3), and when the state of the logic level "0" continuously overflows for a certain time T0 defined by the timer 24 or longer, it is detected that the handset 2 is in the charging state. Yes (STEP 4). In the control unit 23 of the cordless handset 2, the charge state detection unit 22 has
When it is detected that the charging state is changed from the non-charging state due to the overflow of 4, the control when the charging state is changed from the non-charging state, for example, the function of ending the talking state when the handset 2 is in the talking state, Take control.

The logic level of the terminal 2A changes from "0" to "1" (STEP5). The charge state detection means 22 of the slave unit 2 counts the second timer 25 when the logic level of the charge terminal 2A changes from the state of "0", that is, the charge state to the state of the logic level "1", that is, the non-charge state. (STEP 6), when the state of the logic level “1” continuously overflows for a certain time T1 or more defined by the timer 25, it is detected that the handset 2 is in the non-charged state ( STEP 7).

〜10倍程度(数百mSec)とする。If the set value T of the timer 25 is set,
When 1 is in a charging state, the child device 2 is wobbling and charging terminals 1A and 2A
It is set to be shorter than the time when and are separated from each other, and when the handset 2 is lifted while receiving a call, that is, when the handset goes from the charging state to the non-charging state, the call button is immediately pressed. It is assumed that it has a function of making a call to and a function of ending the call when the state of charge changes from the non-charged state to the charged state. If the handset 2 wobbles while charging and receiving a call, the control when the handset goes from the charged state to the non-charged state, that is, the function that enables a call immediately without pressing the call button works. Is in a call. However, since the handset 2 returns to the charging state immediately, the control when the non-charging state is changed to the charging state during the call, that is, the function of ending the call works, and eventually the incoming call cannot be received. There will be an inconvenient period.
Therefore, if the set value of the timer 25 is set to a value T1 that is longer than the time when the cordless handset is wobbled and the charging terminals 1A and 2A are separated from each other, the above-mentioned inconveniences can be solved and the user can be sure. Only when the handset 2 is lifted to the control unit 2
3 controls when the charging state is changed to the non-charging state. This time T1 is about 3 of T0 of the previous timer 24.
Approximately 10 times (several hundred msec).

のがある。As described above, in the cordless telephone of the present invention, when the slave unit is connected to the master unit, the charging state is reached after the first set value of the first timer corresponding to chattering or the like. When the slave unit disconnects from the master unit after detecting that it has entered, after the second set value of the second timer corresponding to the temporary disconnection due to careless external factors By configuring to detect that the charging state has ended, in addition to the user lifting the cordless handset when the vertically oriented cordless handset is in the charging state, external factors such as the user's If the handset touches or the location where the phone is installed wobbles carelessly, the cordless handset erroneously recognizes the charging status. With the function to call immediately without pressing the call button Next, when a call goes from a non-charged state to a charged state during a call, the function of ending the call works continuously, which eventually prevents a problem that there may be a period during which a call cannot be received. Its practical effect is enormous.
