Abstract

A portable storage device with handwritten input device is provided. The portable storage device comprises a storage device and an input device. When the storage device is electrically connected to a host end, an execution program installed in the host end can read coordinates data and the displacement data stored in a flash memory of the storage device and then analyzes and integrates the coordinates data and the displacement data and calculates the coordinates to convert into corresponding text or image files.

Claims

1. A portable storage device with handwritten input device, comprising:

a storage device, comprising a flash memory, a microprocessor electrically connected to said flash memory, a receiving module and a data transmission interface, wherein said data transmission interface is electrically connected to a host end, said microprocessor and said receiving module; and

an input device, comprising a touch device for generating touch signals, displacement signals and coordinates data, and a transmission module for transmitting signals to said receiving module.

2. The portable storage device with handwritten input device as claimed in claim 1, wherein said data transmission interface comprises an IEEE1394 (Institute of electrical and electronic engineers standard bus interface), a USB (universal serial bus), a SATA (serial advanced technology attachment), an IDE (integrated device electronics) or a SCSI (small computer standard interface).

3. The portable storage device with handwritten input device as claimed in claim 1, wherein said flash memory comprises an AND type, a NAND type or a NOR type.

4. The portable storage device with handwritten input device as claimed in claim 1, wherein said receiving module comprises a SPI (serial peripheral interface) or a UART (universal asynchronous receiver/transmitter).

5. The portable storage device with handwritten input device as claimed in claim 1, wherein said receiving module and said transmission module communicate in wired or wireless transmission mode.

6. The portable storage device with handwritten input device as claimed in claim 5, wherein said wireless transmission mode between said receiving module and said transmission module comprises infrared, ZigBee or blue-tooth.

7. The portable storage device with handwritten input device as claimed in claim 1, wherein said host comprises an execution program for analyzing, processing or compressing data.

8. The portable storage device with handwritten input device as claimed in claim 1, wherein said touch device comprises a button, a fine-adjustment switch or a pen point of a handwritten pen.
