[0060] Figure 1A It is a schematic view viewed from above of the end surface inspection device 10 provided with the first processing image data obtaining mechanism 21 and the second processing image data obtaining mechanism 22 and moving the honeycomb structure 1 to obtain image data. Figure 1B as well as Figure 1C It is a diagram showing a part of the end face inspection device 10 viewed from the lateral direction. in addition, Figure 1B It is for the first treatment to obtain the first end surface 2a while irradiating the light 12 with the angle k formed between the axis a perpendicular to the mounting surface 3 of the honeycomb structure 1 of the present invention being 40° or more. The image data method is explained in the figure. in addition, Figure 1C The second processing image of the first end surface 2a is obtained while irradiating the light 12 having an angle k smaller than 40° with the axis a perpendicular to the mounting surface 3 of the honeycomb structur...

[0071] Figure 2A It is a figure which shows 2nd Embodiment of the end face inspection apparatus 10. As shown in FIG. In the second embodiment, an arrangement mechanism 23 , a first light source 11 a, a second light source 11 b, and an imaging device 13 are included. In the second embodiment, the honeycomb structure 1 is arranged at a predetermined position, and the first image data for processing and the second image data for processing are obtained. Also in this embodiment, disposing the honeycomb structure 1 at a predetermined position includes not only placing the honeycomb structure 1 at the predetermined position in a stationary state but also passing through the predetermined position while moving.
[0072]The placement mechanism 23 (stage 14) arranges the honeycomb structure 1 having porous partition walls that define the plurality of cells 5 at a predetermined position so that the second end surface 2b serves as the placement surface 3. 4. The plurality of compartme...

[0082] use Figure 2B as well as Figure 2C A third embodiment will be described. The end surface inspection device 10 of the third embodiment includes an arrangement unit 23 , a first processing image data acquisition unit 21 , and a second processing image data acquisition unit 22 . In addition, an inversion device 28 for inverting the honeycomb structure 1 up and down is included.
[0083] Such as Figure 2B As shown, in the third embodiment, two honeycomb structures 1 are placed on a table 14 as a set and moved. First, the second processing image data of the first end face 2 a is obtained by the second processing image data obtaining means 22 , and the first processing image data of the first end face 2 a is obtained by the first processing image data obtaining means 21 . Thereafter, the honeycomb structure 1 is inverted up and down by the inverting device 28, and image data for processing is similarly obtained for the second end face 2b.
