Abstract

The invention relates to the field of office equipment, and specifically to a scanner. The portable scanner of the invention comprises a scanner body and a power supply device, wherein the scanner body comprises a scanning and sensing system, and the power supply device comprises a USB power module, and a USB power interface which is connected to the USB power module. External equipment is connected to the USB interface through a USB cable by the scanner body, the external equipment transmits low-power electric energy to the USB power interface through the USB cable, the electric energy is transmitted to the USB power module through the USB power interface, and the USB power module converts the electric energy transmitted through the USB cable into high-power electric energy which is capable of driving the scanner body and then provides power for the scanner body. Because of adoption of the above technical solution, the portable scanner of the invention has the advantages of simple structure, compact appearance, and convenient using and carrying.

Description

technical field [0001] The invention relates to the field of office equipment, in particular to a scanner. Background technique [0002] A scanner is an instrument external to a computer that captures images and converts them into an electronic format that a computer can display, edit, store and output for analysis, distribution and archiving. Existing scanners are usually bulky and inconvenient to carry around at any time. Therefore, it is often set on a desk or next to a computer, connected to the computer through a USB cable, and sends the scanned information to the computer. Scanners are usually powered by mains power. If the mains power cannot be connected, the scanner cannot continue to work and is limited in use. [0003] In addition, the scanning sensing system in the scanner, that is, the scanning image acquisition part, is the core part of the whole scanner. Existing scanning sensing systems usually use charge-coupled devices to scan. This type of scanner requir...
