Abstract
A scanner with a built-in microcontroller is provided for decreasing the delay of transmission. The scanner includes: an image-picking device for picking digital data of a plurality of image lines, a microcontroller electrically connected to the image-picking device for continuously detecting whether the image-picking device is ready to scan a second image line after a first image line is picked and send out a digital data which have been picked, and an interface device electrically connected to the image-picking device and a universal serial bus (USB) for receiving the digital data sent out by the image-picking device and transmitting the digital data to a data processing device through the USB.
Claims3
A scanner with a built-in microcontroller to decrease the delay of transmission comprising:
- an image-picking device for picking digital data of a plurality of image lines;
- a microcontroller electrically directly connected to said image-picking device for continuously detecting whether said image-picking device is ready to scan a second image line after a first image line is picked, and for sending out digital data which have been picked, and if said image-picking device is not ready, said microcontroller causing said digital data to wait for said image-picking device to be ready;
- and
- an interface device electrically directly connected to said image-picking device and a universal serial bus (USB) for receiving said digital data sent out by said image-picking device and transmitting said digital data to a data processing device through said USB.
