the reverse side of the film electronic component 10 can be perceived by the color perceptive sensor 2 when the film electronic component 10 is set in a wrong lying position as shown in fig3 b since the stage moving unit 4 moves the carrying stage 1 to position the film electronic component 10 at the predetermined color checking position the color of an optimum region predetermined region 10 a for the type of the film electronic component 10 can be perceived and hence the identification of the film electronic component 10 can be further stably achieved since the data on parameters including identification colors used for identifying film electronic components 10 color checking positions and color checking times for film electronic components 10 of different types are stored in the storage device 5 the operator needs to enter only data on the type of a new film electronic component 10 when the new film electronic component 10 is to be mounted on the glass substrate consequently the time necessary for adjusting the position of the sensor which must be performed by the known component identifying apparatus shown in fig4 can be reduced although the component identifying apparatus in the foregoing embodiment uses the original color of the film electronic component 10 for identifying the film electronic component 10 the film electronic component 10 may be provided with a color.
