DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a date printing printer 1 according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram for explaining the overall configuration of the date printing printer 1. Reference numeral 10 denotes a radio clock module. The radio clock module 10 includes a receiving unit 11 that receives a standard time radio wave, and a radio clock unit 12 that extracts time information from the received radio wave and converts the time information into a standard time code in the region of use. 32 is an I / O unit. The time code output from the radio clock module 10 is latched and transmitted to the CPU 31, and data and print commands output from the CPU 31 described later are transmitted to the printer. 31 is a CPU, and 33 is a ROM. The CPU reads the standard time code from the input port of the I / O unit 32 according to the program recorded in the ROM 33, calculates the expiration date by adding the set best days, and displays the result together with the print command. Output to the output port of the I / O unit 32. Reference numeral 20 denotes a printing printer. The printer 20 includes a printer control unit 21 that generates a control signal to be sent to a printer head and a print ribbon supply mechanism based on print data and a print command instructed via the I / O unit 32, and the control signal The printer mechanism unit 22 indicates a printer head or ribbon supply mechanism that operates based on the printer head.
[0010]
Among these components, all other components except the printer mechanism unit 22 are accommodated in a black box module 30 having tamper resistance. Therefore, the user of the printing printer 1 must open the black box module 30 in order to perform an operation such as replacing the ROM 33 in which the program is recorded in order to improperly print the expiration date or the manufacturing date. At that time, the printing apparatus 1 itself is destroyed. A typical example of the tamper resistant device is an IC card used for recording a secret key for an electronic signature. If you try to steal the secret key, the IC card will be destroyed and you will not be able to use it again. The black box module 30 is similar to this, and the radio clock module 10, CPU 31, I / O unit 32, ROM 33, and printer control unit 21 are configured as a physically integrated structure such as being housed on a single printed circuit board. When attempting to remodel the interior by opening 30, each component itself or their connection is destroyed and cannot be repaired.
[0011]
The date printing printer 1 having the configuration of FIG. 1 always prints the expiration date based on the time calibrated with the standard radio wave according to the program built in the ROM 33.
[0012]
50 is an example of a processed food packaging bag. This product is assumed to be sold in units of this bag 50. 51 is a quality display. 52 is an expiration date display. The expiration date display 52 may be directly printed on the bag 50 by an ink jet printer or the like. However, as shown in FIG. 2A, the expiration date is printed on the hologram processing ribbon 521 and the standard time is displayed. The expiration date display may also be printed with a guarantee mark 522 indicating that the expiration date is printed based on a clock. In this case, the printer 20 is provided with a printer mechanism unit 22 that prints the expiration date and the guarantee mark on the hologram processing ribbon 521 and affixes them to the bag 50.
[0013]
A printer that uses the hologram processing ribbon 521 as an ink ribbon has a rarity, and if the character printed on the hologram processing ribbon is falsified, the hologram ribbon itself is damaged. A certain amount of trust can be given to the deadline display. Further, since the guarantee mark 522 directly guarantees that the expiration date display 52 is displayed by a printer whose time is calibrated, the consumer can purchase the product with the mark 522 with peace of mind. it can.
[0014]
FIG. 2B is a modification of the expiration date display 52. The guarantee mark 522 is omitted. As described above, since the consumer can put a certain amount of confidence in the display of the expiration date printed on the hologram processing ribbon 521, the expiration date printed on the hologram processing ribbon 521 is a special printer whose time is calibrated. 2 is effective, the expiration date display 52 in the form of FIG. 2B is also effective.
[0015]
FIG. 2C shows another modification. A case where the expiration date and the guarantee mark 522 are printed directly on the bag 50 without using the hologram processing ribbon 521 is shown. If the guarantee mark 522 is printed, the expiration date display 52 may be in the form of FIG. 2C if it can be considered that the time is printed by a special printer calibrated. The guarantee mark 522 is printed with the serial number of the black box module 30 of the date printing printer 1 (having an authorization number certifying that the supervisory authority has confirmed the operation of the black box module 30). The reliability of 522 can be improved.
【The invention's effect】
[0016]
As described above in detail, by using the printing printer according to the present invention, with regard to the quality display of foods and processed foods, the display of the best-before date that has been printed from the correct time and the best-before date is linked to the standard time. There is a remarkable effect that it can be provided.
