つとなり製造工程が簡単になるとともに。A thermal paper is brought into contact with the metal electrode, and a wavelength of 7801I is applied.
Ugly GaAJ! An As semiconductor laser was irradiated from the transparent electrode side to record a desired image on the thermal paper. The applied voltage at this time was 20V, the laser output was 5mV, and the printing speed was 1
[Effects of the Invention] According to the configuration of the present invention, element isolation is unnecessary and the drive power supply is reduced to one.
This also simplifies the manufacturing process.
任意場所に記録できるため、解像度が向上する。The resolution is improved because it can be recorded in any location.
