JP 2008-191101 A

  The article inspection apparatus having the inspection function as described in Patent Document 1 is widely used for inspecting the quality of products in the field of food production, for example. The number of persons who can perform operations that affect the inspection results is usually limited to predetermined qualified persons. For this reason, when performing such an important operation, it is necessary to confirm that the worker is a predetermined qualified person, and personal authentication means such as the inspector determination means described above are required.

  However, in the case of performing personal authentication using an authentication card, such as the inspector determination means of the article inspection apparatus of Patent Document 1, the operator performs the authentication operation while holding the card or the like. Although it is convenient for work to hold the card etc. exposed outside, such as hanging a card etc. from the neck, this can not deny the possibility of losing the card etc. and mixing in the raw material, at the site of food production This is not a preferred embodiment.

  In addition, workers engaged in food production wear lab coats and gloves for hygiene reasons, so do not carry cards etc. exposed outside, and put them in lab coats hygienically. Is also preferable. However, holding an authentication card in a lab coat, taking it out and holding it over the authentication device is extremely complicated as a work operation, and each time the card is worn with a gloved hand. There are many hygiene issues to touch.

  Furthermore, as personal authentication means, in addition to such authentication cards and tags, each worker's personal data including operation qualification is encrypted with bar code, QR code (registered trademark), etc. Although a technique given to the worker is also conceivable, according to the authentication means using these cards, tags, barcodes, etc., it is necessary to provide a reading device in the apparatus. However, if such a reading apparatus is provided in an article inspection apparatus, the outer shape of the apparatus becomes complicated, and raw materials and the like are likely to adhere and cause contamination, which is not a preferable method in the field of food production. Furthermore, as a personal authentication means, a method of inputting a password by an input means such as a numeric keypad is conceivable, but it is a hygienic problem to operate the input means many times with a hand wearing gloves. In addition, it is a cumbersome operation in the field of food production that requires frequent personal authentication.

  On the other hand, when the operator performs the authentication operation as described above or inputs any instruction to the apparatus, it is necessary to confirm whether or not the operation has been appropriately performed. However, in a food manufacturing factory, which is the site of food manufacturing, the operation sound of the machine is loud, it is difficult to hear the electronic sound of input confirmation, and there has been a demand for means that can reliably recognize the operation result without relying on voice or the like.

  The present invention has been made in view of the various problems described above, and since the outer shape is not complicated, it is hygienic that foreign matter is less likely to adhere to it, and communication with an operator with high operability without bothering. It is an object of the present invention to provide an article inspection apparatus that can immediately visually confirm the operation result.
