Recently used a lot. In addition, mobile phones and cordless phones, which are lighter and smaller than car phones, have been put to practical use. Such a portable communication device naturally needs a power source for transmission / reception or various kinds of display, and for this reason, it has a built-in battery. As a battery for such an application, a battery having a small shape and a large capacity is required for downsizing of a device, and at present, a Ni-Cd battery is often used.

Various problems occur such that communication cannot be performed and display is not performed. Therefore, a method may be considered in which when the battery level is low, a warning to that effect is given by a display or the like, and the user is prompted to replace the battery. In this case, it goes without saying that communication cannot be performed while the battery is being replaced. However, according to the principle of communication, it is necessary to be able to communicate at any time and at any time, and it is not preferable that the communication be interrupted even when the battery is replaced. Further, even if the user can know that the battery level is low, the battery cannot be replaced without a new battery. This is a serious problem especially in the case of portable communication devices.

することができる。Next, the operation of this embodiment will be described with reference to the flow chart shown in FIG. In the normal communication operation, that is, in the state where the above-mentioned transmission / reception operation is performed, the changeover switch 24 is connected to the main battery 21 side, and power is supplied from the main battery 21 to each unit via the voltage regulator 25. During this communication operation, the CPU 17 detects the remaining amount of the main battery 21 by, for example, passing a current from the power source to the standard load and monitoring the voltage, and determines whether or not this is the specified value or more (steps S1 and S2). .. As a method of detecting the remaining battery level, other methods such as accumulating operating time may be considered. When a secondary battery is used as the main battery 21, the output voltage slightly changes depending on the number of times of use, and the discharge curve is different for each battery. Therefore, the history of battery use is always stored and the history of that battery is stored. By monitoring the remaining battery level with reference, it is possible to accurately estimate the remaining battery level only by monitoring the voltage.

い。Here, when the remaining amount of the main battery 21 falls below a specified value, a warning that the battery is exhausted is given by the display unit 19 or the speaker 15 based on an instruction from the CPU 17, and the changeover switch 24 is also provided. Is switched to the side of the auxiliary battery 22, and power is supplied from the auxiliary battery 22 to each part via the voltage regulator 25 (steps S3 to S4). The fluctuation of the power supply voltage at the time of switching the battery is absorbed by the stabilizing operation of the voltage regulator 25, and it is possible to prevent the operation of each unit from becoming unstable or causing a malfunction. The voltage regulator 25 may be replaced with a simple smoothing circuit. Further, a dedicated voltage regulator may be incorporated for a particularly important circuit.

続けられる。Next, the CPU 17 determines whether or not the main battery 21 has been replaced, and whether or not the replaced new main battery is normal and is supplying a predetermined power supply voltage (steps S5 to S6). If the result of this determination is that the main battery 21 has been replaced and it is normal, the CPU 17 switches the changeover switch 24 to the main battery 21 side, and power is again supplied from the main battery 21 via the voltage regulator 25. (Step S7). Also in this case, the voltage regulator 25 prevents the power supply voltage from changing when the auxiliary battery 22 is switched to the main battery 21. At the same time when the power source is switched to the main battery 21, the auxiliary battery 22 is charged by the output from the main battery 21 via the charging circuit 23 (step S8). The above operation is continued until the CPU 17 determines in step S9 that the communication is completed.

Not only does communication become impossible when the data is exhausted, but the contents of the memory 17, which is generally volatile, may disappear, and information such as the speed dial stored in the memory 17 may be lost. Therefore, after the warning is issued in step S10, the operation is continued until the auxiliary battery 22 consumes a predetermined constant amount of power, and then the communication operation is forcibly cut off (step S11).

Since the switching is performed, it is possible to avoid disconnection of communication until the main battery 21 is replaced, and it is possible to solve the problem that the call is disabled during the call.

Since the battery is charged by the user, the user does not have to be aware of the presence of the auxiliary battery 22 built in the mobile phone in advance, and does not need to be careful about charging the auxiliary battery 22. The auxiliary battery 22 is not limited to one, and a dedicated auxiliary battery may be provided for an important circuit.
