Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to electronic warranty cards.

[0002]

2. Description of the Related Art A conventional electronic guarantee is shown in FIG. FIG.
Is an example of a warranty card for camera film. This guarantee is used for one box containing a plurality of 35 mm films. It is mainly used by each vendor from the manufacturer to the delivery to the retail store to manage in storage box units. The electronic warranty (1) in FIG. 4 is provided with a status history display (2) such as a current time display, a current status display, a status history display (graph) and a comprehensive evaluation display (expressed as an attenuation rate). In the display, output results of information detected by sensors such as a temperature sensor, a humidity sensor, and an illuminance sensor are arithmetically processed and displayed. The state history display (graph) can be switched to humidity or illuminance. The display changeover switch (3) is used for the changeover. Each time the switch is pressed, the temperature, humidity, and illuminance are switched and displayed. Since the comprehensive evaluation display calculates and displays the output from each sensor of temperature, humidity and illuminance, it is displayed while changing momentarily according to the comprehensive judgment result of each output regardless of the state of the selection switch.

[0003]

The electronic warranty shown in FIG. 4 is added to the storage box for the product (35 mm film) and carried to a retail store. When an electronic guarantee is used as a guarantee for managing the state of delivery in units of the storage box, the role of the guarantee is completed when the retail store receives the storage box. If the guarantee is provided for the purpose of guaranteeing the period until the storage box is opened, the role of the guarantee is completed at the time of opening. Generally, a guarantee is provided for a product for the purpose of guaranteeing the product within a limited period within a certain period of time and / or a certain condition. If the term of the product guaranteed by the electronic warranty is sufficiently short compared to the life of the electronic warranty itself, it is possible to reuse the electronic warranty. However, it is feared that the conventional electronic warranty will not operate normally when it is reused due to the influence of being added to a product and transported.

[0004]

The electronic guarantee of the present invention is
In addition to recording and displaying the state history, storing a check pattern for inspecting the function of the electronic warranty, and starting the state history recording when a signal matching the check pattern is given. It is characterized in that it has a function of validating a command, or that a memory for storing the check pattern is detachable from the electronic warranty.

[0005]

The electronic warranty has a check pattern for checking its function, and has a function of activating a command for starting the state history recording when a signal matching the check pattern is given. By doing so, when the electronic warranty is reused, the work of confirming its function can be surely performed. Further, by making the memory for storing the check pattern detachable, the check pattern can be kept secret, so that the confirmation work becomes more reliable.

[0006]

FIG. 1 shows a first embodiment corresponding to claim 1 of the present invention. The electronic warranty (1) is provided with a state history display (2 '), a display changeover switch (3'), a warning light (4), a temperature sensor (5) and an auxiliary temperature sensor (5 '). . When the electronic warranty is actually added to a product, the temperature of the temperature sensor and the temperature of the auxiliary temperature sensor are compared, and if the mutual measurement temperature difference is within a predetermined range, the product is normally measured. It recognizes and records and displays the history, and when it is out of the range, it recognizes that it is abnormal and blinks the warning light. The cause of the above abnormality may be a failure of the electric circuit of the electronic warranty itself, but it may also be an external factor that happens to be cold air blown to the position of the temperature sensor and the temperature is extremely lower than the position of the auxiliary temperature sensor. . The electronic warranty is set so that history recording and display will continue even if an abnormality occurs. When the warning light is flashing, the display changeover switch is operated to scroll the state history display to confirm the time and state of the abnormality.

The reset switch (6) in FIG.
It has a function of starting history recording and display by pressing the electronic warranty when attaching it to a product. When attaching to frozen foods, for example, when attaching the electronic guarantee written at room temperature to frozen foods, the temperature sensor of the electronic guarantee must be able to accurately measure the temperature of the frozen foods.
It takes about a minute. Since it is preferable to press the reset switch immediately before attachment in consideration of workability, this electronic guarantee certificate for frozen foods incorporates a delay circuit so that history is recorded 2 minutes after the reset switch is pressed. When it is used as a warranty, its meaning will be faint if it is unnecessarily reset while it is attached to the product. In order to prevent this reset operation on the way, the reset operation can be performed only once unless a special procedure is taken.

The electronic warranty is used, for example, after being attached to a frozen product to a retail store and then peeled off at the retail store. If this electronic warranty can be reset again,
Can be reused at the next frozen food shipment. As mentioned above, it is necessary to prevent unnecessarily resetting on the way, and it is necessary to reconfirm normal operation because the reliability of the electronic warranty that has been placed in the distribution once and left is not reliable. In order to satisfy the above, in the electronic warranty shown in FIG. 1, the electronic warranty is returned to a state in which the reset operation can be performed by the following procedure.

A constant temperature is applied to each of the temperature sensor and the temperature auxiliary sensor. As an example of the method, there is a method of adding it to constant temperature soda. The temperature of the constant temperature soda is set to 3 at regular intervals.
Give different types. The heating pattern by the constant temperature soda is stored in the check pattern memory (7). The circuit is set so that the electronic warranty can be reset when the heating pattern of the constant temperature soda matches the heating pattern stored in the memory. For example, as shown in the graph of FIG. 2 (horizontal axis is time axis, vertical axis is temperature axis), three kinds of temperatures of (A), (I), and (U) are given according to the temperature pattern shown in the graph. The temperature measurement timing of the electronic warranty is ,,,,
Is the time point indicated by. For example, the interval is 1 minute. By accurately creating the temperature pattern shown in FIG. 2 with constant temperature caustic and comparing it with the contents of the check pattern memory of the electronic warranty, it is possible to check the measurement accuracy and reliability of the electronic warranty.

By making the heating pattern a pattern that cannot occur in the normal use state, it is possible to prevent the resetting state from being erroneously made in the state of being attached to a normal product. By making the patterns of the temperatures given to the temperature sensor and the auxiliary temperature sensor different, it is possible to easily create a temperature pattern that cannot normally occur.

Further, setting is made such that a resettable state is set when a specific temperature pattern appears within a certain period of time after pressing a switch such as the reset switch and the display changeover switch provided in the electronic warranty. This further reduces the possibility of accidental resetting during normal use.

In the state history display, in addition to displaying the temperature history and the presence / absence of contents to be warned during one transportation period of frozen food, the number of times the electronic guarantee is reset and used is also displayed.

FIG. 3 shows an example of a heating method for returning to the resettable state. It is the figure which looked at electronic guarantee (1) from the side. The temperature sensor (5) and the auxiliary temperature sensor (5 ') are arranged on the front and the back of the electronic certificate, and the temperature sensor and the auxiliary temperature sensor can be easily connected by the heating heater of the pen-shaped temperature measuring scissors (8). It is designed to be sandwiched. A specific temperature pattern is easily provided by the heater.

An embodiment corresponding to claim 2 of the present invention will be described with reference to FIG. The embodiment of the present invention is characterized in that the check pattern memory in FIG. 1 is removable. Depending on how it is used, the electronic warranty may be in the middle of not knowing how it was handled. For example, when an automobile manufacturer consigns a vehicle to a vehicle carrier and delivers the automobile, the electronic warranty during transportation is handled out of reach of the attached automobile manufacturer. In this case, if the check pattern is incorporated in the electronic warranty, there is a risk that it will be decrypted or altered. In order to prevent this, the check pattern memory is made removable so that, for example, the check pattern memory can be used by incorporating it in the electronic warranty only when the resettable state is reset It is effective to lose. As another example, the chuck pattern memory is kept built in even while the electronic warranty is attached to the product and used, but if in doubt, the check pattern memory can be easily replaced for inspection. It is possible to make it easy to put on and take off so that it can be done. By making the chuck pattern memory detachable in this manner, the reliability when the electronic guarantee certificate is reproduced and used is improved.

Although an example has been described above centering on a warranty card with a built-in temperature sensor as an electronic warranty card, the same can be done for humidity, impact, and chemical change amount as history measurement.

[0016]

[Effect of the Invention] Even if the electronic warranty of the present invention has a history of being used by being attached to a product in the past, a reset operation is performed so that it cannot be used again as a warranty unless the history recording and display functions are inspected. Since it has the function of suppressing, it is possible to reduce the risk of being reused without checking the function by mistake. Furthermore, by making the check pattern memory detachable, the function confirmation work can be performed reliably and easily.
