ABSTRACT

A laser test device for a laser selection includes a roll-to-roll unit, a
laser irradiation unit, and an inspection unit. The roll-to-roll unit includes
a supply roller for unwinding a substrate sheet and a winding roller for
rewinding the substrate sheet, and roll-to-roll unit transports the substrate
sheet at a predetermined speed. The laser irradiation unit includes a laser
oscillator, a scanner and an optical system, and irradiates a laser beam for
notching the substrate sheet being transported to thereby form a plurality of
extension tabs in the substrate sheet. The inspection unit is positioned at
the rear of the laser irradiation unit and obtains a magnified image of the
notched area of the substrate sheet being transported.
