Zusammenfassung: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. 【課題】コストを低減することが容易な光学検査装置及び製函装置を提供する。【解決手段】光学検査装置2は、ブランクシートAを搬送方向Bに搬送する第1搬送機構3と、第1搬送機構3の搬送方向下流側に離間して配置され、ブランクシートAを第1搬送機構3から受け取って搬送する第2搬送機構4と、照明部5,6と、光が照射されたブランクシートAを撮像位置P3で撮像する撮像部7とを備え、放出位置P1と受入位置P2との間の離間距離がブランクシートAの搬送方向に沿う長さLの1/3に満たず、照明部5,6は、光を出力する光源51,61と、光源51,61から出力された光が、第1搬送機構3と第2搬送機構4とが互いに対向する領域で第1搬送機構3と第2搬送機構4とに挟まれた空間である離間空間Sを介してブランクシートAに照射されるように光を導びく導光部材52、ハーフミラー63とを含んだ。【選択図】図3
