Mouse capable of freely switching right and left key

A mouse allows free shift between the left and right press keys, which is achieved by a hardware circuit consisting of two symmetric transistor circuits arranged side by side and a control switch (30) that controls the working status of the transistor circuits. When the first transistor circuit is in operation under the control of the switch, signals generated by the left and right press keys are transmitted through the first transistor circuit (201) to the left and right input pins of a corresponding integrated chip (50), and vice versa, when the second transistor circuit (202) is in operation under the control of the switch, signals generated by pressing the left press key is transmitted to the input pin of the right press key (402), while signals generated by pressing the right press key (102) is transmitted to the input pin of the left press key, thus realizing free shift between the left and right press keys of the mouse through the switch. With the invention, the shift between the ...

Display with peripheral interface and computer system thereof

The invention relates to a computer system, comprising a displayer and a host computer, wherein the displayer comprises at least one external interface for connecting an external device of the computer system to receive an external signal, and an integrated interface to be connected with an external interface. The computer system also comprises an external signal transmission line, wherein one end of the external signal transmission line is connected with the integrated interface of the displayer, while the other end of the external signal transmission line is connected with the host computer for transmitting the external signal received by the external interface of the displayer to the host computer. The computer system can allow a plurality of external interfaces to be arranged on the displayer, so that wired external devices can be directly connected to the displayer through the external interfaces, infrared signals transmitted by external infrared devices can be received directly through ...
