NOVELTY - The mouse (200) has a mouse body (201) generating a wireless signal, and a wireless signal receiver (202) for receiving the wireless signal. A battery receptacle is provided within the mouse body for accommodating a battery. A battery cover (206) is pivotally coupled to the mouse body. A receiver holder (207) is fixed on the battery cover for accommodating the signal receiver. The receiver holder is located within the mouse body when a battery access inlet (205) of the receptacle is sheltered by the battery cover. The receiver holder is exposed when the battery access inlet is exposed.    USE - Wireless mouse for holding a wireless signal receiver for a personal computer.    ADVANTAGE - The mouse allows the receiver holder to be exposed when the battery access inlet is exposed, so as to facilitate insertion/removal of the wireless signal receiver into/from the receiver holder of the mouse body without using a doorlock element. The wireless signal receiver is connected to the universal serial bus (USB) port of the computer, so that the signals generated from the mouse can be transmitted to the computer via the wireless signal receiver. The mouse minimizes probability of losing the wireless signal receiver even when the ribs are loosened or the clamping effect is reduced. The mouse avoids usage of additional connecting wire to be connected with the computer, so that the use of the mouse is more convenient. The mouse enables wireless peripheral device such as wireless earphone and wireless keyboard to be communicated with the computer according to a wireless transmission technology.    DETAILED DESCRIPTION - The wireless signal receiver is electrically connected to a personal computer through a universal serial bus (USB). The receiver holder is made of plastic material.
