Send to.
Furthermore, as another embodiment, information indicating the customer's age or age group is acquired from the mobile terminal 4 as the customer's attribute, and recipe information having the most suitable content for the customer is transmitted to the mobile terminal 4. That is, if the customer is a relatively young customer, the recipe information including the detailed contents is transmitted to the mobile terminal 4 of the customer, and if the customer is a middle-aged or elderly customer, the recipe information expressed in a simple content is transmitted. It transmits to the customer's portable terminal 4.

  In the next step S14, recipe information matching the customer's attribute is read from the recipe information file 15c. This is for changing the expression of the recipe information to be transmitted to the mobile terminal 4 according to the customer attribute. For example, the recipe information file 15c shown in FIG. 5D is prepared corresponding to a plurality of languages. That is, in the example of FIG. 5D, the recipe information is expressed in Japanese, but the same contents are prepared in languages such as Korean, English, Chinese, etc. In step S14, in step S13, Recipe information expressed in a language corresponding to the language used as a customer attribute is read from the recipe information file 15c. The read recipe information is stored in a predetermined memory area of the RAM 14.

In the next step S15, the read recipe information is transmitted to the mobile terminal 4 of the customer by the short-range communication unit 16. Thereby, the customer's portable terminal 4 receives the recipe information transmitted from the electronic shelf label 1 by the short-range communication unit 16 and displays it on the display unit.

In FIG. 12, recipe names, ingredients, and how to make are displayed as recipe information in Japanese.
FIG. 13 shows a display example (Korean notation) of recipe information on the mobile terminal 4 of the customer. In the example of FIG. 12, in step S13, the customer attribute indicating the language used “Korean” is acquired from the portable terminal 4, and in step S14, the recipe information expressed in Korean is read from the recipe information file 15c and carried. The case where it transmitted to the terminal 4 is shown. That is, in the case of a customer who uses Korean, recipe information expressed in Korean is transmitted to the mobile terminal 4 of the customer. In FIG. 13, recipe names, ingredients, and how to make are displayed as recipe information in Korean.
FIG. 14 shows a display example (in English) of recipe information on the customer's mobile terminal 4. In the example of FIG. 12, in step S13, a customer attribute indicating the language used “English” is acquired from the portable terminal 4, and in step S14, recipe information expressed in English is read from the recipe information file 15c and the portable terminal 4 is read. Shows the case of being sent to. That is, in the case of a customer who uses English, recipe information expressed in English is transmitted to the mobile terminal 4 of the customer. In FIG. 14, recipe names, ingredients, and how to make are displayed as recipe information in English.
Thus, in this embodiment, since the recipe information expressed in the language according to the language used by the customer is transmitted from the electronic shelf label 1 to the customer's portable terminal 4, the customer immediately receives the acquired recipe information. Can be understood and used.

  In step S16, the system waits for a response signal transmitted from the customer's mobile terminal 4 to be received by the short-range communication unit 16. That is, in step S15, recipe information is transmitted from the electronic shelf label 1 to the customer's portable terminal 4, and when the customer's portable terminal 4 receives the recipe information, the customer's portable terminal 4 transmits a response signal to the electronic shelf label 1. . In this case, it is assumed that the customer's mobile terminal 4 is also provided with a short-range communication unit equivalent to the short-range communication unit 16 of the electronic shelf label 1.

In step S17, it is determined whether or not the transmission of the recipe information to the customer mobile terminal 4 is completed, that is, whether or not the response signal transmitted from the customer mobile terminal 4 is received by the short-range communication unit 16. . If it is determined in step S17 that the transmission is not completed (step S17; NO), the process returns to step S16 and a response signal is waited.
If it is determined in step S17 that the transmission is completed (step S17; YES), the recipe transmission process shown in FIG. 7 is terminated.

  Next, the traceability transmission process executed by the electronic shelf label 1 will be described with reference to FIG. In this traceability transmission process, in response to the customer operating the traceability key 11b provided on the electronic shelf label 1, the CPU 10 of the electronic shelf label 1 reads the traceability information stored in the storage unit 15 and reads the traceability information read out. The information is transmitted to the customer's mobile terminal 4 by the short-range communication unit 16. FIG. 8 is a flowchart showing the operation of the traceability transmission process. This traceability transmission process is executed under the control of the CPU 10 of the electronic shelf label 1.

First, in step S21, it is determined whether or not “traceability key operation?”, That is, whether or not the recipe key 11b of the input unit 11 has been operated by the customer. If it is determined in step S21 that the traceability key 11a is not operated (step S21; NO), step S21 is repeatedly executed. If it is determined in step S21 that the traceability key 11b has been operated (step S21; YES), the process proceeds to step S22.
In step S22, mutual communication with the customer's portable terminal 4 is performed as in step S12 of FIG. That is, the CPU 10 of the electronic shelf label 1 transmits a request signal for requesting transmission of attribute information indicating the customer's attribute to the customer's mobile terminal 4 from the short-range communication unit 16, and in response thereto, the mobile terminal 4 Is received by the short-range communication unit 16, and the received attribute information is stored in a predetermined memory area of the RAM 14. After execution of step S22, the process proceeds to step S23.

In step S23, as in step S13 of FIG. 7, the CPU 10 determines the customer attribute based on the attribute information stored in a predetermined memory area of the RAM 14. In this embodiment, customer attributes include, for example, the language used by the customer (Japanese, Korean, English, Chinese, etc.), whether the customer is a customer, customer age or age group. means. In the present embodiment, the representation of the traceability information transmitted to the mobile terminal 4 is changed according to the customer attribute determined in step S23.
For example, as one embodiment, information indicating a language used is acquired from the mobile terminal 4 as a customer attribute, and traceability information expressed in a language used by the customer is transmitted to the mobile terminal 4. That is, in the case of a customer who uses Japanese, traceability information expressed in Japanese is transmitted to the mobile terminal 4 of the customer, and in the case of a customer who uses Korean, the traceability information expressed in Korean is transmitted to the customer's mobile phone. In the case of a customer who uses English, traceability information expressed in English is transmitted to the mobile terminal 4 of the customer.
