  Among hotels, especially in hotels located adjacent to the international airport (hereinafter referred to as international airport hotels), the following special circumstances exist. In other words, at international airport hotels, the ratio of foreigners to customers is overwhelmingly high. Therefore, it cannot be expected that the customer has a specific membership card, but on the other hand, most of the check-ins are presented with a passport. In many countries, the passport uses paper as a medium, and the spread of IC etc. cannot be expected so much. In this case, in accordance with the law, it is necessary to have a passport presented at the time of check-in, and a staff member at the front desk copies the page including the photo (or creates image data) and saves it. In addition, transit customers often have a contract with a specific hotel for each arriving plane, so hundreds of customers are concentrated at the same time for check-in. Furthermore, it is more realistic to have a certain number of staff members waiting at the front of the hotel in preparation for various troubles.

  As described above, according to the study of the present inventor, at an international airport hotel, rather than simply automating the entire front desk of the hotel, check-in confirmation processing and issuance of a room key (card key) It is more realistic to automate processing to some extent.

  Preferably, in the room key issuing system of the present invention, the check-in system further includes display means for displaying the acquired reservation information. The result of the character recognition includes at least a nationality. The display means displays the acquired reservation information in the official language of the country based on the nationality included in the character recognition result.

  According to the room key issuing system of the present invention, character recognition is performed by extracting image information of the second area including characters from the image information of the first area including the photograph read from the passport, and performing OCR processing on the extracted image information. (Acquire character information), acquire reservation information based on the result of character recognition, and issue a room key based on the reservation information. Accordingly, image data of a page including a passport photo can be created and stored in accordance with the law without human intervention. Further, it is possible to perform check-in confirmation processing by acquiring reservation information without human intervention, and it is possible to perform room key issuing processing for issuing a room key.

  According to the room key issuing system of the present invention, the read image information of the first area is temporarily stored in the storage unit, but is deleted from the storage unit after acquiring the reservation information. As a result, the image data of the passport photo can be saved, while the image information can be deleted from the check-in system to protect the personal information.

  According to the room key issuing system of the present invention, the acquired reservation information is displayed in the official language of the country based on the nationality included in the character recognition result. Thereby, the hotel customer can confirm the reservation information accurately, and the check-in confirmation process can be smoothly performed to prevent the occurrence of trouble in advance.

  FIG. 1 shows an example of the configuration of the room key issuing system of the present invention. The room key issuing system is a passport check-in system that reads a passport 4 and automatically issues a room key such as a card key 5. The room key issuing system includes a check-in system 1, a hotel front system 3, and a network 2 that connects them. The network 2 includes, for example, the Internet, an in-house LAN (Local Area Network), and the like.

  The check-in system 1 is a computer that automatically performs check-in for hotel customers, and is provided in a hotel check-in counter or the like. The check-in system 1 includes a reading processing unit 11, an image information storage unit 14 as an image information storage unit, a reservation information processing unit 15 as a reservation information acquisition unit, a card key issuance processing unit 16, an image scanner 17, and a display device 18. A card key issuing device 19 is provided. The reading processing unit 11 includes an image information processing unit 12 and an OCR processing unit 13 as a character information recognition unit. The reading processing unit 11 (particularly, the image information processing unit 12) and the image scanner 17 constitute a reading unit that reads image information. The card key issuing processor 16 and the card key issuing device 19 constitute issuing means for issuing a card key. The reservation information processing unit 15 and the display device 18 constitute display means for displaying reservation information.

  The hotel front system 3 is a computer that manages various front services of a hotel, and is provided in a hotel front or a management room. The hotel front system 3 includes an image information management unit 21, a reservation information management unit 22, an image information master (file) 23, and a reservation information master (file) 24. The image information management unit 21 and the image information master 23 constitute an image information management unit. The reservation information management unit 22 and the reservation information master 24 constitute reservation information management means.

  When the hotel customer inserts the passport 4 into the image scanner 17, the image scanner 17 reads the image information 141 in the first region R1 of the passport 4 as shown in FIG. 141) is transmitted to the reading processing section 11.

  The region R1 is a page (region including a photo) on which the photograph of the person is pasted in the passport 4, and is usually the last page of the passport 4. The electronic data (image information) on this page is required by law. As shown in FIG. 2A, the region R1 includes the region R2 in the bottom column. The region R2 is a region including characters, and usually includes a description (character string) in 2 to 3 lines of alphabet. This description consists at least of name and nationality.

  Note that the image scanner 17 may read the entire opened page of the passport 4. In this case, the image information processing unit 12 extracts the image information 141 of the predetermined region R1 from the read image.

  The hotel customer is instructed to insert the passport 4 into the image scanner 17 after opening the page of the passport 4. Instead of this, the image scanner 17 may be provided with means for turning the page of the known passport 4.

  When the read processing unit 11 receives the image information 141 from the image scanner 17, the image information processing unit 12 temporarily stores (stores) the image information 141 of the first region R1 in the image information storage unit 14. Then, the storage completion is notified to the OCR processing unit 13. By this storage, image information 142 is obtained in the image information storage unit 14. “Temporarily” means that the image information 142 of the first region R1 is deleted from the image information storage unit 14 by the image information processing unit 12, as will be described later. Deleted by customer check-in.

  As shown in FIG. 2B, the OCR processing unit 13 reads the image information 142 of the first region R1 from the image information storage unit 14, and extracts the image information 143 of the region R2 to be character-recognized therefrom. Since the size of the passport 4, the position of the photograph and the character string, etc. are determined in advance, the size of the area R1 and the position of the area R2 can be known in advance.

  In FIG. 2B, image information 141 and image information 143 are shown in association with each other in order to indicate the corresponding area. Further, the image information processing unit 12 may extract the image information 143 of the region R2 from the image information 142 of the image information storage unit 14.

  As shown in FIG. 2B, the OCR processing unit 13 performs well-known OCR processing (character recognition processing) on the extracted image information 143 to extract character information 144. In the region R2, since the character is usually printed clearly in alphabet, the character recognition rate is almost 100%. As described above, the character information 144 that is a result of character recognition includes the name and nationality. The OCR processing unit 13 sends the extracted character information 144 to the reservation information processing unit 15.

  The reservation information processing unit 15 requests the reservation information management unit 22 to make a reservation information inquiry based on the result of character recognition, and acquires the reservation information as a result of the inquiry from the reservation information management unit 22. Further, the reservation information processing unit 15 temporarily stores the read image information 142 of the first region R1 in the image information storage unit 14, and after acquiring the reservation information, temporarily stores it in the image information storage unit 14. The image information 142 of the first area R1 is deleted.

  Specifically, the reservation information processing unit 15 makes an inquiry about the reservation information 241 (see FIG. 4) using the character information 144 to the hotel front system 3 via the network 2. That is, as shown in FIG. 4, the reservation information processing unit 15 transmits an inquiry request for reservation information (241) together with the character information 144 to the reservation information management unit 22 of the hotel front system 3. And the reservation information processing part 15 acquires the reservation information corresponding to the said character information 144 by receiving the response according to the said inquiry request | requirement from the reservation information management part 22. FIG.

  Here, the reservation information management unit 22 stores a plurality of reservation information 241 in advance in the reservation information master 24 as shown in FIG. One piece of reservation information 241 stores information such as reception date, room number, stay schedule, meal, departure flight, check-in, etc. according to the name and nationality of the customer who made the reservation. The room number is assigned when the reservation is accepted. In international airport hotels, since many of the customers are usually transit, the stay schedule indicates the date of stay (usually only one day). Meals indicate whether or not breakfast is provided the day after staying. Since the departure flight is a transit, it indicates the flight of the departure flight on the day after the stay. Check-in indicates the presence or absence, and for example, “0” and “1” indicate a non-check-in state and a checked-in state, respectively.

  When the reservation information management unit 22 receives the inquiry request for the reservation information 241, the name and nationality in the plurality of reservation information 241 of the reservation information master 24 using the character information 144 (that is, name and nationality) included in the inquiry request. As shown in FIG. 4, one line (one record) of the reservation information master 24 including the nomination and nationality matching the name and nationality in the character information 144 is extracted. Based on the result of this extraction, the reservation information management unit 22 creates reservation information 241. In this example, the reservation information 241 includes a room number and a stay schedule in the extracted record. In FIG. 4, only the room number is shown for convenience of illustration.

  Note that the reservation information 241 may consist of the entire extracted record. Further, the reservation information 241 may be composed of the name, nationality, room number, and stay schedule in the extracted record. In this case, when the reservation information 241 is displayed on the display device 18, only the reservation information 241 can be displayed on the display device 18 without using the character information 144 as described later. The reservation information 241 may include at least a room number.

  As shown in FIG. 4, the reservation information management unit 22 transmits the extracted reservation information 241 as a response to the reservation information processing unit 15 that is the inquiry source. If there is no reservation information 241 that matches the character information 144 in the reservation information master 24, the response is an error notification. In addition, for customers of a specific nationality, when their names are written in alphabets, they often have the same name. Therefore, even when there are a plurality of matching reservation information 241, the response is an error notification. In addition, the reservation information management unit 22 sends the character information 144 included in the inquiry request to the image information management unit 21.

  The display device 18 displays the acquired reservation information 241. That is, after acquiring the reservation information 241 as described above, the reservation information processing unit 15 displays the acquired reservation information 241 together with the character information 144 on the display device 18 as shown in FIG. When a customer who looks at the display device 18 presses a confirmation button (not shown), the reservation information processing unit 15 requests the image information processing unit 12 to transmit the image information 142.

  FIG. 5A shows an example of a screen displayed on the display device 18. That is, the name (NAME), nationality (NATIONALITY), date of stay (DATE), and room number (ROOM NUMBER) are displayed in a predetermined language (for example, English). The name and nationality are obtained from the character information 144 and expressed in alphabets. The date of stay and the room number are obtained from the reservation information 241 and expressed in numbers.

  On the other hand, when an error notification is received instead of the reservation information 241, the reservation information processing unit 15 displays a request (instruction) text for the customer on the display device 18. For example, a sentence “Please go to the front desk to proceed” is displayed in a predetermined language (for example, English). As a result, when the reservation information 241 does not exist or when a plurality of reservation information 241 exist, the customer checks in face-to-face with the clerk at the front desk.

  Note that this sentence may be displayed in the official language of the country based on the nationality included in the character information. In this case, the reservation information processing unit 15 is provided with the sentences corresponding to a plurality of nationalities in advance, and selects and compares sentences in any one or a plurality of languages according to the nationalities.

  Further, when the confirmation button is not pressed within a predetermined time (for example, 20 to 30 seconds) from the display, the same display is performed from the viewpoint of crime prevention.

  When the image information processing unit 12 is requested to transmit the image information 142 from the reservation information processing unit 15, the image information management unit of the hotel front system 3 stores the image information 142 temporarily stored in the image information storage unit 14. After that, as shown in FIG. 2B, the image information 142 is deleted from the image information storage unit 14. As a result, the passport image information including personal information such as a photo, name, and nationality can be stored only in a predetermined area of the hotel front system 3, and the personal information can be protected.

  When the image information management unit 21 receives the image information 142 from the image information processing unit 12 of the check-in system 1, as shown in FIG. 5B, the image information management unit 21 stores the image information 142 together with the character information 144 included in the inquiry request. Store in the master 23. As a result, the image information 231 of the first area is permanently stored in the image information master 23. “Permanently” is, for example, a legally long storage period or a sufficiently long period compared to temporary storage in the image information storage unit 14. Thus, the image information master 231 can store the image information 231 of the page (area R1) including the passport photo for each customer checked in by the check-in system 1 using the passport.

  Note that the image information 231 of the region R1 also includes the image information 143 of characters printed in the region R2, as described above. Therefore, the storage of the character information 144 included in the inquiry request may be omitted.

  When the image information management unit 21 finishes storing the image information 231 of the first region R1 in the image information master 23, the image information management unit 21 notifies the reservation information management unit 22 of the completion. Upon receiving this notification, the reservation information management unit 22 changes the “check-in” information of the customer in the reservation information master 24 from “0” indicating incomplete to “1” indicating completion.

  As described above, when the transmission of the image information 142 ends, the image information processing unit 12 notifies the reservation information processing unit 15 of the end of transmission as a response to the request. In response to this notification, the reservation information processing unit 15 sends the reservation information 241 to the card key issue processing unit 16.

  The card key issuing processing unit 16 causes the card key issuing device 19 to issue the card key 5 based on the acquired reservation information 241. That is, when receiving the reservation information 241, the card key issuance processing unit 16 transmits an issuance command for the card key 5 to the card key issuing device 19 together with the reservation information 241. As shown in FIGS. 5C and 5D, the card key 5 is a card-type key and includes a magnetic recording unit 51 on the back surface thereof. When receiving the card key 5 issuing command, the card key issuing device 19 magnetically writes the reservation information 241 in the magnetic recording unit 51 of the card key 5 (creates the card key 5) as shown in FIG. This is issued to the customer.
