Title:
INKLESS PRINTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/262442
Kind Code:
A1
Abstract:
An inkless printing device, comprising a frame (10), a bottom plate (20), a light-transmitting plate (30), and a laser emitter (40). The bottom plate is arranged at the bottom of the frame and is used for carrying paper to be printed; the light-transmitting plate is movably connected to the frame by means of the first driving mechanism (31); the first driving mechanism can drive the light-transmitting plate to move toward the bottom plate, so that the light-transmitting plate is attached to the bottom plate and presses the paper; the laser emitter can emit laser to burn and carbonize the paper through the light-transmitting plate. The inkless printing device can solve the problems in the prior art of printing failure and paper burning caused by a laser burning printing device being prone to excessive burning.
