PURPOSE: A lens module of a bar code pen scanner is provided to increase the productivity by forming a light emitting diode capable of scanning light and a condensing lens capable of condensing reflected light as one module, and by cutting down the cost of production. CONSTITUTION: A light emitting diode(1) scans light. A lens(2) condenses reflected light. A condensing plate(4) condenses light to a slot(3). The light emitting diode(1), the lens(2) and the condensing plate(4) are combined with a module body(5). The module body(5) forms a cap assembling screw(7) on leading end. In addition, the module body(5) forms a case assembling screw(8) on after-edge. Grooves(9, 9') are formed on both sides of the leading end in the cap assembling screw(7). In addition, A connection terminal(11) of the light emitting diode(1) is inserted and combined into an assembling hole(10). The condensing plate(4) installed in the back of the cap assembling screw(7)is assembled by a combination ring(12).
