Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data processing device using a non-contact data storage body for performing automatic settlement of purchased commodities, for example, automatic settlement of dishes purchased at a cafeteria cafeteria.

[0002]

2. Description of the Related Art In recent years, cafeteria type cafeterias use a device for saving the labor of manually inputting the amount of money for each dish into a register device at the time of payment. As a device for such labor saving, the applicant of the present invention has filed Japanese Patent Application No. 6-
No. 93328 “Data processing device using non-contact data storage” is proposed. A data device that uses this non-contact data storage (hereinafter simply referred to as a data processing device, if necessary) automatically reads the purchase price of the dish and calculates the total amount, which is then placed on the container. When a desired dish is selected from a variety of prepared dishes, placed on a tray, and carried to a predetermined place of the settlement place, the purchase price of the dish is automatically read and the total price is calculated.

FIG. 6 is a diagram for explaining the overall configuration in which this conventional data processing device is applied to the calculation of purchase charges in a cafeteria cafeteria, and FIG. 7 is a block diagram showing the electrical configuration of this data processing device. It is a figure. In FIG. 6 and FIG. 7, in this example, the settlement counter 4 which is a settlement place for the purchase price of food is driven by the reader / writer 10 to form a service area (communicable area) by a plurality of transmission / reception coils. The coil unit 12 is arranged. A table 15 is provided near the settlement counter 4. A container 20a, 20b, 20 in which a plurality of desired dishes are placed on the tray 18 at a cooking place (not shown) by the user
c is placed and carried on the table 15. Further, when the user pays the bill, the tray 18 is moved to the billing counter 4.

Each of the containers 20a to 20c is provided with a data storage body 22a, 22b, 22c at the bottom thereof, and the amount data of the dishes is stored in advance. When the tray 18 is placed on the settlement counter 4, the amount data is read by driving the coil unit 12 from the reader / writer 10 and transferred to the register device 16. The register device 16 totalizes and displays the prices of a plurality of dishes. This total amount is paid in cash, or
A prepaid card, a postpaid card, a credit card, or the like is used, and payment is made through the reader / writer device.

Alternatively, payment is made through a host computer which is a higher-level device connected to the register device 16. In such a process, in the reader / writer 10 shown in FIG. 7, the control unit 10a receives a command indicating that the tray 18 is placed on the coil unit 12, for example, a command from a contact push switch or a non-contact optical switch. Recognizes by capturing by interrupt processing.

After that, the control unit 10a controls the transmission / reception coils 12a, 12b, 12c, 12 of the coil unit 12 through the reading unit 10b and the coil switching unit 10c.
Commands, address data, etc. are simultaneously modulated by FSK (Frequency Shift Keying) from d, 12e, and 12f and transmitted. The data storage bodies 22a to 22c, which have received the command, the address data, etc., sequentially convert the amount data stored here into pseudo random data signals and send them to the transmission / reception coils 12a to 12f.

The pseudo random data signal of the monetary amount data is controlled by the control unit 10a so that the reading unit 10b and the coil switching unit 10c cause the transmitting / receiving coil 1 of the coil unit 12.
2a to 12f are sequentially switched and transmitted, and input to the correlation calculation unit 10d in FIG. When the correlation calculating unit 10d obtains an autocorrelation exceeding a predetermined threshold value, the amount data obtained by restoring the high-level autocorrelation value bit is sent to the register device 16 through the control unit 10a.

As described above, in this settlement, although the name of the dish and the amount of the dish are automatically input to the cash register, the settlement time for delivering the total amount of cash becomes long. You can use prepaid cards, postpaid cards, credit cards, and pre- and post-payment payments by host computer processing for this payment, but in this case, it is necessary to arrange a dedicated reader / writer device to withdraw from these cards. , It takes a lot of time to operate it, and the settlement at the cafeteria cafeteria is delayed,
This leads to an increase in costs associated with the arrangement of the device.

[0009] As a proposal for improving the settlement delay as described above, there is the "settlement device" disclosed in Japanese Patent Laid-Open No. 4-350791. In this example of the publication, the settlement process is performed quickly and accurately by using a data carrier.
The tableware recognition data carrier using PROM etc. is provided in the tableware. Furthermore, a personal identification data carrier using an EEPROM storing a personal code read from a personal identification (ID) card by a card reader is arranged on a tray on which tableware is placed.

When the tray is brought to the settlement place, the tableware recognition data carrier and the individual recognition data carrier transmit the tableware recognition data and the individual recognition data to the inquiry data from the control unit, and the identified individual The settlement data for each is created, and the automatic settlement can be performed by a data processing device such as a computer.

[0011]

As described above, in the settlement device described in the above publication, the settlement data for each individual is created by the read tableware recognition data and the individual recognition data, and the automatic settlement is possible. , Has the following drawbacks. (1) The reader / writer device requires an input operation to read the personal code from the identification card, which requires time and labor for the operation, delays the settlement at a cafeteria cafeteria, and increases the cost associated with the placement of the reader / writer device. Will be invited. (2) The data read from the identification card by the reader / writer device is only the personal code, and the settlement data for each personal code is created by the data processing device and the settlement such as actual cash delivery will be performed at a later date. In other words, automatic payment at the time of purchase using a prepaid card, a postpaid card, a credit card, etc. which are widely used is impossible. (3) Since the reader / writer device reads only the personal code from the identification card, various data processing cannot be performed. For example, it is impossible to reduce the amount of money with a prepaid card, add with a postpaid card, perform billing processing with a credit card, and record a purchased product on a card, so that the degree of freedom of use of the device cannot be obtained.

The present invention solves the problems in the prior art as described above, and enables quick and reliable calculation of the total price of purchased commodities and automatic settlement thereof, and enables various data processing.
