Description:
TECHNICAL FIELD 
       [0001]    The present invention relates to a mouse. 
       BACKGROUND ART 
       [0002]    With development of computers, small and portable mice are gaining more and more popularity in the market. However, it is often inconvenient to operate mice that are too small. When a user operates a mouse, he/she needs to not only operate functional keys but also control movements of the mouse. Excessively small mice can often only accomplish operation by means of strength of fingers of the user, and this easily causes fatigue of the user and malfunctions. 
         [0003]    To solve the aforementioned problem, China Patent ZL200720119517.8 “Fingerstall Type Mouse” discloses a small mouse, in which a body of the mouse is a small flat board and for convenience of operating the mouse by a user, a fixed shell is disposed on the flat board to cover fingers of an operating hand of the user so as to facilitate the user to accomplish moving and positioning of the mouse. However, the fingerstall shell that is fixedly disposed not only adds the volume of the mouse but also makes it difficult for most of users to comfortably and conveniently operate the mouse because fingers of the users are often much different from each other in thickness. 
       SUMMARY OF THE INVENTION 
       [0004]    The technical problem to be solved by the present invention is to provide a mouse that has a small volume and is convenient to operate. 
         [0005]    The objective of the present invention is achieved through the following technical solution: 
         [0006]    The present invention provides a mouse comprising a base, functional keys disposed on the base, and an optical transmitting and receiving device configured to transmit and receive data information, wherein the mouse further comprises a finger-back pressure plate movable connecting to the base. 
         [0007]    Through the aforesaid technical solution, when a user uses the optical mouse, the finger-back pressure plate hinged with the base is opened to press the finger-back of an operating hand. In this way, when moving the optical mouse, the user can easily and conveniently operate the optical mouse without applying a too large force thereon by means of his/her fingers. 
         [0008]    To further improve cooperation between the operating hand of the user and the finger-back pressure plate, in some embodiments provided by the present invention, the finger-back pressure plate is formed with a finger-back through-hole thereon. When the user operates the mouse and the finger-back of the operating hand is pressed by the finger-back pressure plate, a finger-back portion of the operating hand corresponds to the finger-back through-hole. In this way, when the finger-back pressure plate is rotated at a certain angle relative to the base and presses the finger-back of the operating hand of the user, an arched portion of the finger-back of the operating hand passes through the finger-back through-hole. Thus, the finger-back through-hole  210  also provides a certain force for moving the mouse. 
         [0009]    In some embodiments provided by the present invention, the mouse may further have the following characteristics: 
         [0010]    In order to facilitate the user to operate the mouse even when the finger-back pressure plate is not opened, functional key through-holes are formed at positions on the finger-back pressure plate corresponding to the functional keys. Thus, when the finger-back pressure plate is closed, the user controls the functional keys via the functional key through-holes by means of the fingers of the operating hand so as to use the mouse. 
         [0011]    Protrusions are disposed on the functional keys for increasing sensitivity and a friction force between the fingers of the operating hand and the functional keys. 
         [0012]    A cushion is disposed at the side of the finger-back pressure plate corresponding to the finger-back. 
         [0013]    The finger-back pressure plate is rotatably connected to the base. 
         [0014]    The finger-back pressure plate is movably connected to the base via a pressure plate hinge disposed between the base and the pressure plate; the functional keys are disposed at the side of the base adjacent to the pressure plate hinge, and the functional keys include a left functional key and a right functional key. The mouse can be operated by either a left hand or a right hand. The aforesaid hinge connection may also be replaced with a pivot connection, a detachable connection and the like. 
         [0015]    The mouse further comprises a scroll wheel disposed at a side of the base, and the scroll wheel is a scroll gear wheel, a rough-surface wheel or a sliding touch key. 
         [0016]    The optical transmitting and receiving device comprises a light source, an optical system mirror and a reflected-light receiving device provided with an optical lens, which are disposed in an optical component case; and light emitted by the light source is irradiated to a reflecting surface through the optical system mirror, then reflected by the reflecting surface and received by the reflected-light receiving device. 
         [0017]    The mouse further comprises the optical component case, at least the light source, the optical system mirror or the reflected-light receiving device of the optical transmitting and receiving device are contained in the optical component case, and the optical component case is movably connected with the base. In this way, when the optical component case is rotated at a certain angle relative to the base, a distance between the optical transmitting and receiving device and the reflecting surface is increased, thereby improving a resolution ratio and sensitivity of the mouse. 
         [0018]    The reflecting surface is often a surface that supports the mouse to move thereon. 
         [0019]    The reflected-light receiving device often has a lens. When the optical component case is received in the optical component case groove within the base, the lens of the reflected-light receiving device and the reflecting surface have a small distance there-between, and a focal length of the lens often extends beyond the reflecting surface actually, resulting in an unsatisfactory focusing effect. However, when the optical component case is rotated at a certain angle relative to the base and has an increased distance from the reflecting surface, the area irradiated by the light source through the optical system mirror is increased and the reception focusing effect and the resolution ratio are improved. Of course, an optical system having a short focal length may also be employed to solve the aforesaid technical problem that the optical component requires to be moved to increase the distance from the reflecting surface. 
         [0020]    The light source is an electronic component that emits visible light, infrared light or laser light. 
         [0021]    At a position on the base corresponding to the optical component case is formed an optical component case groove for accommodating the optical component case. 
         [0022]    The mouse may be connected in a wireless or wired way. When the mouse is connected in the wireless way, the mouse comprises a wireless transmitting device and a wireless receiving device. The wireless receiving device is pluggable into and removable from a computer via for example a USB interface and is configured to be wirelessly connected between the mouse and the computer. Some computers may already have a wireless receiving system (e.g., a Bluetooth system) built therein, and can be wirelessly connected with this mouse. The mouse is formed with a wireless receiving device groove for receiving the wireless receiving device. The wireless transmitting device is connected with a circuit board of the mouse. 
         [0023]    The wireless connection can be accomplished by using infrared light, high-frequency radio, Bluetooth and the like. 
         [0024]    Of course, the mouse of the present invention may also be connected with the computer in the wired way. 
         [0025]    Compared to the prior art, the present invention has the following advantages: the mouse is more convenient to operate while being small in volume and portable; meanwhile, there is no need to additionally apply a down force, thereby avoiding malfunctions and allowing the user to use the mouse easily for a long time.
