Abstract:
A pen-sized keyboard arrangement, for being connected with a PDA, a mobile phone, and other information products, comprising:a rolling mechanism including a base and a rolling pole pivotally connected with the base, the rolling pole defining an elongated cavity inside and defining a longitudinally extending elongated assembling groove therein, one end of the rolling pole being pivotally connected to the base, the other end thereof being rotated by a hand; a keyboard member at least including a pair of flexible PCBs, a flexible film sandwiched by the PCBs, and a mother board electrically connected to the flexible PCBs, a plurality of key-presses being printed on one flexible PCB, a touch pad being positioned on the other flexible PCB corresponding to the key-presses; a buffer being formed on each of the flexible layers to limit the movement direction of the flexible layers so that the flexible layers can only move in a direction of being rolled thereby absorbing the deformation of each flexible layer during the process of being rolled; a housing with a cavity inside including a pair of openings at opposite ends thereof for receiving the base and the rolling pole, and defining an elongated assembling slot corresponding to the assembling groove of the rolling pole; and an electrical connection unit at least including a connector for being electrically connected from the keyboard member to an information product.
