PURPOSE: A horizontal system having a beam generator is provided to have a laser generator examining the laser beam into slope diction of horizontal, vertical, and 45 degree, thereby measuring and displaying the horizontal, perpendicularity and slope of the measuring place. CONSTITUTION: A horizontal detecting element(200) embeds the bubble and is installed to the groove formed in upper side of the horizontal system body to horizontal direction. The perpendicular element(300) embed the bubble and is installed to the horizontal direction inside the horizontal system body and is read through cut-out unit included to the left and right both side of the horizontal system body. A laser generator(400) is installed to the one side of the upper part of the horizontal system body and the laser beam is fired. A power supply unit(600) supplies power the lighting device(500) and the laser generator.
