<p>PROBLEM TO BE SOLVED: To provide an optical inspection apparatus and a box making apparatus in which costs can be easily reduced.SOLUTION: An optical inspection apparatus 2 comprises: a first transfer mechanism 3 which transfers a blank sheet A in a transfer direction B; a second transfer mechanism 4 which is disposed separately on a transfer direction downstream side of the first transfer mechanism 3, receives the blank sheet A from the first transfer mechanism 3 to transfer it; illumination parts 5, 6; and an imaging part 7 which images the blank sheet A irradiated with light at an imaging position P3. The separation distance between a discharge position P1 and a reception position P2 is less than 1/3 of a length L along the transfer direction of the blank sheet A. The illumination parts 5, 6 comprise light sources 51, 61 for outputting light, light guide members 52 which guide light so that the light emitted from the light sources 51, 61 are irradiated on the blank sheet A via a separation space S being a space sandwiched by the first transfer mechanism 3 and the second transfer mechanism 4 in a region where the first transfer mechanism 3 and the second transfer mechanism 4 face each other, and half mirrors 63.</p> |
