[Conventional technology]

Electronic devices such as cordless telephones are usually connected to a power source and are A base unit that sends and receives calls, displays incoming calls, etc. is installed separately from the base unit, and is powered by a rechargeable battery. The device is equipped with a handset that allows you to send and receive calls, display incoming calls, display the amount of battery charge, etc. this The base unit receives, sends, records, displays incoming calls, etc. using the power supply, so the amount of charge of the power supply There is no need to check etc.

0003 However, handsets use rechargeable batteries to receive, send, and display incoming calls. If you do not monitor the charge level of the rechargeable battery, the charge level of the rechargeable battery will become insufficient and you will not be able to continue making and receiving calls. There are times when I become unable to listen.

0004 One way to monitor the amount of charge of this rechargeable battery is to use a light emitting diode in the power supply circuit of the rechargeable battery.

When the light emitting diode 22 is reduced to one, the No matter how you choose the installation location, the display of indicator 14 will be on the front of handset 10. The problem is that even if you can see it, it becomes difficult to see from the rear or side. be.

0010 Moreover, since the light emitted from the light emitting diode 22 is linear, the two colors shown in FIG. In the light emitting diode 22, the vertical directivity characteristics of red 1 and green 2 are about 10 degrees each. The parallel directivity characteristics of Red 1 and Green 2 are each about 20°. (Figures 11 and 12), it is said that these lights cannot be properly monitored over a wide area. There's a problem.

[0011] In order to solve this problem, the present invention provides a light emitting device that displays the amount of charge of the rechargeable battery. The purpose is to obtain a handset of a cordless telephone that displays information in a diffused manner.
