An apparatus for marking an edible object, comprising: a carrier means (20, 30) for conveying the edible object, a detecting means (210, 310) for detecting the edible object, a marking means (220, 320) for forming a marking pattern (M1, M2) on the edible object, and a marking inspecting means (230, 330) for inspecting the marking pattern (M1, M2) formed on the edible object, the carrier means (20, 30) sequentially conveying the edible object to the detecting means (210, 310), the marking means (220, 320), and the marking inspecting means (230, 330) while holding the edible object, wherein the detecting means (210, 310) and the marking inspecting means (230, 330) each comprise an irradiating part (212, 232, 312, 332) for irradiating the edible object and an imaging part (214, 233, 314, 334) for capturing an image of the edible object, characterised in that the detecting means (210, 310) captures an image of the edible object to acquire orientational data indicating orientation of the edible object; the marking means (220, 320) forms the marking pattern (M1, M2) in accordance with the orientation of the edible object based on the orientational data; the marking inspecting means (230, 330) captures an image of the edible object, extracts marking pattern data, and compares the marking pattern data with reference pattern data based on the orientational data acquired by the detecting means (210, 310) to thereby inspect marking accuracy, wherein an angle (α) between an irradiating direction and an imaging direction in the detecting means (210, 310) and an angle between an irradiating direction and an imaging direction in the marking inspecting means (230, 330) are mutually different. a carrier means (20, 30) for conveying the edible object, a detecting means (210, 310) for detecting the edible object, a marking means (220, 320) for forming a marking pattern (M1, M2) on the edible object, and a marking inspecting means (230, 330) for inspecting the marking pattern (M1, M2) formed on the edible object, the carrier means (20, 30) sequentially conveying the edible object to the detecting means (210, 310), the marking means (220, 320), and the marking inspecting means (230, 330) while holding the edible object, wherein the detecting means (210, 310) and the marking inspecting means (230, 330) each comprise an irradiating part (212, 232, 312, 332) for irradiating the edible object and an imaging part (214, 233, 314, 334) for capturing an image of the edible object, characterised in that the detecting means (210, 310) captures an image of the edible object to acquire orientational data indicating orientation of the edible object; the marking means (220, 320) forms the marking pattern (M1, M2) in accordance with the orientation of the edible object based on the orientational data; the marking inspecting means (230, 330) captures an image of the edible object, extracts marking pattern data, and compares the marking pattern data with reference pattern data based on the orientational data acquired by the detecting means (210, 310) to thereby inspect marking accuracy, wherein an angle (α) between an irradiating direction and an imaging direction in the detecting means (210, 310) and an angle between an irradiating direction and an imaging direction in the marking inspecting means (230, 330) are mutually different. the carrier means (20, 30) sequentially conveying the edible object to the detecting means (210, 310), the marking means (220, 320), and the marking inspecting means (230, 330) while holding the edible object, wherein the detecting means (210, 310) and the marking inspecting means (230, 330) each comprise an irradiating part (212, 232, 312, 332) for irradiating the edible object and an imaging part (214, 233, 314, 334) for capturing an image of the edible object, characterised in that the detecting means (210, 310) captures an image of the edible object to acquire orientational data indicating orientation of the edible object; the marking means (220, 320) forms the marking pattern (M1, M2) in accordance with the orientation of the edible object based on the orientational data; the marking inspecting means (230, 330) captures an image of the edible object, extracts marking pattern data, and compares the marking pattern data with reference pattern data based on the orientational data acquired by the detecting means (210, 310) to thereby inspect marking accuracy, wherein an angle (α) between an irradiating direction and an imaging direction in the detecting means (210, 310) and an angle between an irradiating direction and an imaging direction in the marking inspecting means (230, 330) are mutually different.
