Abstract: The present invention discloses an improved foot pad structure of a mouse, including: a mouse housing, having a top surface and a bottom surface; at least one foot pad, disposed on a bottom surface of the mouse housing, and made of a ceramic material or a glass material for providing wear-resisting, low friction, low worn-out features as well as an easy sliding operation while sliding on a plane, so as to give a smooth movement with a better displacement operability, and enhance practicability, cost effectiveness and product competitiveness.

Abstract: The present invention discloses a palm support structure of a mouse, and the palm support structure includes an ergonomic auxiliary body installed on a lateral edge or a rear position of a mouse body and combined with the mouse body. When a user operates the mouse, the user's palm is attached onto a surface of the mouse body surface, and the user's two outer fingers of the palm or the user's wrist are supported by the auxiliary body, such that the fingers or the wrist will not touch a tabletop directly to provide a comfortable operation of the mouse for users.

Abstract: A wireless cursor indicating device includes a first body and a second body combined with each other. The first body includes a containing space for containing a control circuit and a wireless receiver, and ends of the first and second bodies include a positioning member and a wheel, and a latch is disposed between the first and second bodies, such that the first and second bodies can be turned with respect to each other by the fixing member and wheel to define a closed status when the first and second bodies are stacked with each other or an open status when the first and second bodies are disposed alternately with each other. The first and second bodies can be disposed alternately with each other by the effect of the latch, such that a containing space is exposed to facilitate users to access or storage objects in the containing space.

Abstract: A wireless cursor indicating device includes a first body and a second body combined with each other. The first body includes a containing space for containing a control circuit and a wireless receiver, and both sides of the first and second bodies include a sliding track and a sliding groove embedded with each other, and an elastic member and a limit member are embedded between the first and second bodies, so that the first and second bodies can be slid with respect to each other by means of the sliding track and sliding groove to define an OFF state or an ON state. With the operation of the elastic member and limit member, the first and second bodies in the ON state can be pulled by the elastic member without being disposed alternately, and only the containing space will be exposed for an easy access by users.

Abstract: An input device adaptable to a cabled or a wireless mouse includes a receiver connected to a PC via transmission cable and provided on its slope a first latch, a second latch being disposed on a slope of a wireless mouse that contains a charging battery; both latches being locked to each other for the PC to charge the wireless mouse when the battery power in the wireless mouse is at low lever without interrupting the connection between the wireless mouse and the receiver.

Abstract: A mouse is internally provided with a data processor for the mouse to read data stored in a memory card, and an I/O interface for connecting the data processor to a microcontroller in the mouse. The microcontroller is connected to a coordinate output circuit normally provided in a mouse, and to a computer via a Universal Serial Bus (USB) interface. Whereby, the mouse not only functions like a normal mouse, but also enables direct data transmission between a memory card and a computer via the mouse without the need of an external data processor. The mouse also facilitates access of data having middle to small volume from a computer and storage of the accessed data into a memory card that is portable to any place for use. High-volume compact discs and expensive apparatus for such purpose, such as recording machine, CD-ROM, MO, etc., could be saved.
