It has become.

  As the IC tag 6, a known passive IC tag as described above is applied, but an active IC tag may be used.

  Next, the structure of the reader unit 7 will be described with reference to FIGS. 3 to 5. The reader unit 7 is a main body formed of a stainless steel plate material, which is a metal material, in a box shape having a horizontally long rectangular shape with an upper surface opened. It is comprised from the part 7a and the mounting part 7b arrange | positioned so that the upper surface opening of the main-body part 7a may be obstruct | occluded, and the sushi plate 3 can be mounted in an upper surface. In the present embodiment, the main body portion 7a is made of a stainless steel material, but may be made of a metal material other than stainless steel, or may be made of a material other than a metal material capable of shielding electromagnetic waves. It may be.

  The main body portion 7a is composed of a bottom wall 20 and a side wall 21 standing from its peripheral edge, and a flange portion 22 extending substantially horizontally outward is continuously provided from the upper end of the side wall 21 by bending. . The flange portion 22 is formed in an annular shape at the upper peripheral edge of the main body portion 7a.

  Inside the main body 7a, a substrate cover 17 that accommodates a leader substrate 16 on which a control circuit 14, a storage unit, and the like are mounted is disposed at a corner portion. A material 18 (not shown in FIG. 3) is disposed. The wiring K extending from the control circuit 14 is inserted to the outside through an insertion hole (not shown) formed in the side wall of the main body 7 a and is connected to the control unit 10 of the control unit 8.

  As shown in FIG. 3, the antenna 15 is annularly arranged along the inside of the side wall 21 in the main body 7a, that is, along the periphery of the upper surface opening of the main body 7a. As shown in FIG. 5, the flange portion 22 is disposed at substantially the same height. That is, since the flange portion 22 extending in the horizontal direction is disposed along a straight line that faces in a direction substantially orthogonal to the axis of the antenna 15, the electromagnetic wave from the antenna 15 is transmitted to the body portion 7 a. It can be effectively attenuated near the outside.

  A cover member 23 made of a synthetic resin material is disposed above the antenna 15, and the upper surface opening of the main body portion 7 a excluding the upper surface of the substrate cover 17 is closed. A closing plate 24 made of polyethylene and a work plate 25 are disposed.

  The closing plate 24 and the work plate 25 are formed in a plate shape that is substantially the same shape as the outer peripheral edge of the flange portion 22 in plan view. The closing plate 24 is formed by adhering the peripheral edge of the lower surface of the closing plate 24 and the upper surface 22a of the flange portion 22 in a water-sealed state with a rubber packing 26 as a sealing material so that the upper surface opening of the main body portion 7a is closed. The main body 7a is fixed to the main body 7a, thereby preventing water or the like from entering the main body 7a in which the control circuit 14, the antenna 15 and the like are built.

  On the other hand, the work plate 25 placed on the upper surface of the closing plate 24 has a flat upper surface 25a, and a plurality of (eg, ten) sushi dishes 3 can be placed on the upper surface 25a. It has a size (see FIG. 7C). Further, since it is provided so as to be detachable from the closing plate 24, it can be washed in a state of being detached from the closing plate 24 when the upper surface 25a serving as a cooking surface becomes dirty. Thus, by providing the work plate 25 detachably on the upper part of the closing plate 24, the working plate 25 can be cleaned without damaging or damaging the closing plate 24 fixed to the main body portion 7a in a water-sealed state. It can respond by exchange.

  Next, the ID reading status of each sushi plate 3 by the reader unit 7 configured as described above will be described with reference to FIG.

  FIG. 6 shows a state in which the control circuit 14 of the reader unit 7 is driven and electromagnetic waves are transmitted from the antenna 15. In this way, the electromagnetic wave is transmitted so as to spread in the circumferential direction about the axis of the antenna 15 as indicated by the dotted line in the figure. The antenna 15 is arranged at the upper part in the main body part 7a configured in a box shape whose upper surface is opened by a stainless steel plate, which is a metal material, so that the upper surface 25a of the work plate 25 arranged at the upper part of the main body part 7a. There is no metal material or the like that interferes with electromagnetic waves in the entire area, and almost the entire area of the upper surface 25a of the work plate 25 becomes a readable area, so that it is stored in the IC tag 6 of the sushi plate 3 placed on the upper surface 25a. The ID can be read reliably.

  On the other hand, in the vicinity of the outer side of the main body part 7a, the electromagnetic wave transmitted from the antenna 15 interferes with the side wall 21 of the main body part 7a and the flange part 22 extending outwardly from the side wall 21 and is attenuated. That is, the electromagnetic wave does not interfere with the metal material in the upper region of the upper surface 25a, which is the region immediately above the main body portion 7a, but the electromagnetic wave in the position near the outside of the main body portion 7a is attenuated by the interference with the flange portion 22. Since electromagnetic waves do not easily reach the vicinity of the IC tag 6 of another sushi plate 3 (such as the sushi plate 3 loaded on the right side in FIG. 6) placed near the outside of the main body 7a. Reading the ID stored in the tag 6 is prevented.

  In order to attenuate the electromagnetic wave in the position near the outside of the main body portion 7a in this way, it is conceivable to make the side wall 21 thick. However, making the wall thickness increases not only the weight but also the manufacturing cost. Therefore, it is possible to reduce the weight by using the flange portion 22 extended outward in order to place the closing plate 24 on the main body portion 7a, and to effectively reduce electromagnetic waves in the vicinity of the outer side of the main body portion 7a. Can be attenuated.

  Next, FIG. 7 shows a procedure for registering before supplying information (quantity, variety, amount, etc.) relating to sushi prepared by cooking with the reading device 5 comprising the reader unit 7 and the control unit 8 to be supplied to the restaurant. This will be explained based on. Here, according to the situation of the sushi being circulated and conveyed in the circulation conveyance path 1a, the cook cooks, for example, “large Toro (480 yen)” for a plurality of dishes and puts it in the circulation conveyance path 1a. The case where it supplies to a restaurant is demonstrated as an example.

  In addition, cooking of sushi to be supplied to restaurants and registration work such as varieties and quantity information are performed by the cook as determined by the state of the sushi that has been introduced into the circulating transport path 1a and being transported in a circulating manner as in this embodiment. It is not limited to a thing, You may be performed according to the order from a restaurant, etc.

  As shown in FIG. 7A, the cooking table 4 is provided with the reader unit 7 and the control unit 8 as described above, and a plurality of sushi plates 3 are located near the reader unit 7. Are arranged in a loaded state. The plurality of sushi plates 3 include four types of sushi plates 3a to 3d (for example, sushi plate 3a is a 120-yen plate, sushi plate 3b is a 240-yen plate, sushi) The plate 3c is a 350-yen plate and the sushi plate 3d is a 480-yen plate). The amount information is registered in advance in the management computer 9 in association with each ID stored in the IC tag 6 provided in the various sushi dishes 3a to 3d.

  When the cook cooks and supplies “Large Toro (480 yen)”, first, the control unit 8 is activated, and the cook ID that can identify the cook to cook on a predetermined registration screen (not shown) or the like. By inputting necessary items such as, a registration screen as shown in FIG. 7A is displayed on the display 11.

  Next, the type of sushi to be supplied (type of material) is registered. Here, since the “Large Toro (480 yen)” material 32 and the material IC card 30 prepared for each type of material 32 are supplied to the cook by the bat 31, FIG. As shown in b), by placing the material IC card 30 on the upper surface 25a of the work plate 25, the card ID stored in the placed material IC card 30 is read by the reader unit 7, The read card ID is transmitted to the management computer 9 via the control unit 8.

  In the management computer 9, since the type of material is registered in the database (not shown) in association with the card ID of various types of IC cards, the material type information (material name) registered in association with the received card ID. And money amount information) are extracted, and the extracted material type information is returned to the control unit 8 together with the card ID.

  The control unit 8 that has received the material type information and the card ID extracts the material name and money amount information included in the received material type information and displays them on the registration screen. Here, as shown in FIG. 7B, “large toro” is displayed in the “name of material” item, and “480 yen plate” is displayed in the item of “plating plate”.

  In this embodiment, the type of sushi to be supplied (type of material) is registered by reading the material IC card 30 with the reader unit 7 and based on the type information registered in association with the read card ID. However, without using such a material IC card 30, for example, it may be possible to register by selecting a sushi variety (material type) using the switch 12 a of the control unit 8 or the like. .

  If sushi is supplied by an order from a restaurant, for example, order information is transmitted from an ordering device (not shown) to the control unit 8, and the sushi varieties included in the transmitted order information are automatically selected. It may be registered.

  Next, the cook takes out the material IC card 30 from the upper surface 25a, and places a plurality of sushi plates 3d, which are 480 yen plates, on the upper surface 25a of the work plate 25 (here, 10). Here, the ID stored in the IC tag 6 of each sushi plate 3d placed on the upper surface 25a of the work plate 25 is read by the reader unit 7, and corresponds to each ID based on the read ID. The amount information is confirmed by the management computer 9, and the quantity of the read ID is calculated and displayed on the registration screen. As shown in FIG. 7C, when 10 sushi dishes 3d are placed on the upper surface 25a, “480 yen dish” is displayed in the “type of dish” item, “10” is displayed in the item.

  Here, when the amount information (480 yen plate) registered and displayed by the news item IC card 30 is different from the amount information of the sushi plate 3 actually placed and read on the upper surface 25a, a predetermined amount is set. Error notification (error sound output, error display on display 11, etc.) is performed and the registration process is interrupted, so the cook puts sushi 2 on the wrong sushi plate 3 Supply to food and drink is prevented. In particular, since a plurality of sushi plates 3 are registered and supplied at a time, before the sushi 2 is served, the amount information registered by the neta IC card 30 and the sushi placed on the upper surface 25a and read. Comparison with the amount information of the plate 3 is performed, and when the comparison result does not match, error notification is performed, thereby preventing troubles such as redoing the arrangement.

  After the sushi 2 has been placed on all the sushi plates 3d placed on the upper surface 25a, the cook has supplied the sushi plates 3 placed on the upper surface 25a to the customers. From the three supply categories “lane (circulation conveyance path 1a)” “order (dinner)” “take (takeout)” displayed on the registration screen in FIG. By selecting the item corresponding to the category that supplied 3d, and finally selecting the “Register” item, 10 dishes of “Large Toro (480 yen)” will be added to the “lane”, “order”, and “take” at a predetermined time. Supply information indicating that it has been supplied to one of them is transmitted to the management computer 9 together with each ID. For the same material type, the number of supplied sheets can be added sequentially until the “Register” item on the registration screen is selected.

  The management computer 9 that has received the supply information manages the supply status of the sushi to the customers based on the received ID and information on the type, amount, amount, etc. of the sushi 2 supplied to the customers included in the supply information. To do.

  As described above, in the reader unit 7 constituting the reading device 5 as an embodiment of the present invention, since there is no stainless material in the upper surface opening of the main body portion 7a made of stainless steel, If the sushi plate 3 is placed on the upper surface of the placing portion 7 b, that is, the upper surface 25 a of the work plate 25, information is transmitted between the antenna 15 of the reader unit 7 and the IC tag 6 of the sushi plate 3 by electromagnetic waves transmitted from the antenna 15. Is surely sent and received.

  Further, in the vicinity of the outer side of the main body portion 7a, the electromagnetic wave transmitted from the antenna 15 is attenuated by interference with the side wall 21 of the main body portion 7a and the flange portion 22 extending outward from the side wall 21. Information is prevented from being sent to and received from the IC tag 6 of another sushi plate 3 placed near the outside of the plate. Therefore, even when the reader unit 7 is used in the cooking table 4 on which the other sushi dishes 3 are arranged, the mounting portion 7b can be mounted on the main body without increasing the thickness of the side wall 21 of the main body portion 7a made of a metal material. Since the electromagnetic waves in the vicinity of the outside of the main body portion 7a can be attenuated by using the flange portion 22 to be placed on the portion 7a, the sushi 2 supplied to the eating and drinking customers can be managed accurately.

  In addition, since the antenna 15 is disposed at substantially the same height as the flange portion 22, the antenna 15 can be disposed as close as possible to the sushi plate 3 placed on the upper surface 25a. By arranging the portion 22 on a straight line that faces in a direction substantially orthogonal to the axis of the antenna 15 or along the straight line, it is possible to effectively attenuate electromagnetic waves in the vicinity of the outside of the main body portion 7a. .

  Further, the antenna 15 is disposed along the periphery of the upper surface opening of the main body portion 7a, so that a communication region can be provided over the entire upper surface 25a of the placement portion 7b.

  Moreover, since the mounting portion 7b is fixed to the upper surface 22a of the flange portion 22 in a water-sealed state via a rubber packing 26 as a sealing material, it is possible to effectively prevent water from entering the main body portion 7a. By increasing the width dimension of the flange portion 22 in this manner, the area sealed by the rubber packing 26 and the like is increased, and not only the stability of the closing plate 24 is improved, but also the electromagnetic waves in the vicinity of the outer side of the main body portion 7a. Can be attenuated more effectively.

  FIG. 8 is an enlarged cross-sectional view showing a main part of a reading apparatus as a modification of the present invention. In the above embodiment, the side wall 21 and the flange portion 22 attenuate the electromagnetic wave in the vicinity of the outer side of the main body portion 7a. For example, as shown in FIG. The extending vertical piece portion 22b may be provided continuously, and by doing so, a metal material is also present above the flange portion 22, so that the electromagnetic wave in the vicinity of the outer side of the main body portion 7a is further reduced. It can be effectively attenuated.

  Further, by extending the vertical piece 22b to the side surface of the work plate 25, the horizontal movement of the work plate 25 disposed on the upper surface of the closing plate 24 is restricted. There is no need to separately form a locking portion or the like for locking.
