In addition, the first output terminal and the second output terminal may be composed of different kinds of USB ports. Specifically, USB 2.0 Type A, USB 2.0 Type B, USB 2.0 Mini Type B ), USB 2.0 Micro Type B (Micro 5 pin), USB 3.0 Type A, or USB 3.0 Type B. In the case where the output terminal is composed of the above-described USB port, a separate cable is required to be connected between the wireless mouse and the external device to be charged. Since a cable is used, And the external device can be charged at the same time during use of the wireless mouse itself.

Meanwhile, the wireless mouse according to the present invention may be a structure capable of directly charging an external device when connected to an external device, and the output terminal may have a USB connector structure. When the wireless mouse is directly connected to an external device to be charged, it is not necessary to carry a separate cable, so that the wireless mouse can be used more easily.

As described above, when the output terminal has the structure of the USB connector, a wire electrically connecting the USB connector and the second battery cell is housed in the wire housing part in the mouse housing in a winding state, And a removable cover may be mounted on the cover.

Meanwhile, in order to allow the user to easily find out the remaining charge amount of the mouse according to the present invention, the user can easily supply the insufficient power when necessary, so that the low power state of the second battery cell is displayed on the outer surface of the mouse housing And the display unit may be formed of an LED. At this time, the low power state can be set in a range of 30% or less based on the fully charged state. Therefore, when the remaining charge amount of the second battery cell of the mouse drops to 30% or less of the fully charged state, the LED display unit may send a signal indicating that the battery is in the low power state .

The wireless mouse according to the present invention may be included in the device main body, but the device main body may be, for example, a notebook computer main body, a smart pad main body, a wearable electronic device main body, or a desk- .

Since the device body or devices are known in the art, a detailed description thereof will be omitted herein.

As described above, the wireless mouse according to the present invention employs the auxiliary battery in the empty space of the wireless mouse carried with the portable computer, so that the auxiliary battery can supply not only the power for the wireless mouse but also the power for the external device It is possible to solve the problem of volume and weight increase when a separate auxiliary battery is carried, and it is possible to supply power to the mobile device with an easy method, so that the problem of insufficient battery capacity can be solved easily .
