Description of the Related Art A battery checker has a pattern layer and a temperature-indicating ink layer formed on one side of a base film such as a strip of paper or a plastic film, and a conductive layer formed on the other side. This battery checker generates heat when voltage is applied between the terminals.
The temperature-indicating ink layer has the function of changing color in response to the heat conducted through the base film. The degree of change in the battery voltage is detected by the degree of change in the area of the temperature-indicating ink layer that is developing color.

In both cases, the temperature-indicating ink layer starts to develop or change color when the temperature reaches a predetermined temperature.

I end up. The degree of decrease in battery voltage can be detected by the degree of decrease in the area of the color-producing temperature-indicating ink layer, so in the case of ■, it is impossible to recognize the degree of decrease in battery voltage. It was extremely difficult to use.

たりして使用上不都合なことが多いものであった。[0005] In the case of (2), the battery voltage is sufficient at first, and the entire surface of the temperature-indicating ink layer develops color, and as the voltage is consumed, the color develops continuously and steplessly starting from the wider part of the heat generating part. A color display is performed in which the color area decreases. In this case, it is possible to recognize the degree of decrease in battery voltage. However, the color development of the temperature-indicating ink layer disappears continuously and steplessly in a so-called analog manner as the battery voltage decreases. Therefore,
It is difficult to understand the degree of change in the area of the colored portion, and it is not easy to recognize the degree of decrease in the colored area at a glance. The degree of change in battery voltage can be detected by the degree of change in the area of the color-producing temperature-indicating ink layer, so the degree of change in battery voltage in the case of ■ cannot be determined by relying on numbers on the scale. Naturally, it is not easy to visually recognize the remaining amount of voltage at a glance. As a result, while using the battery, it is often inconvenient to use the battery because it is almost time to replace the battery or the battery is past the time to replace it.

FIG. 3 is a cross-sectional view. A conductive layer 2 is formed on one side of the base film 1, and a pattern layer 3 and a temperature-indicating ink layer 4 are formed on the other side.

Further, when the heat generated in the conductive layer 2 is strong, it is preferable that the base film 1 has heat resistance.

The conductive layer 2 is a layer that connects a pair of terminal parts for inputting and outputting current without disconnection, and has a heat generating part that generates resistance heat by passing the current. The conductive layer 2 is made of conductive metal, metal compound, carbon, etc., and specifically, conductive paste film, conductive ink film, conductive coating film, vapor deposition thin film, ion plating film, sputtering film, etc. There are membranes, metal foils, plated membranes, etc.

It consists of 2. The planar shape of the heat generating portion 22 is such that its width changes in stages.

The shape may be one-sidedly tapered in five steps: a, 22b, 22c, 22d, and 22e (see FIG. 1). The width is constant within each stage. With such a shape, when a constant voltage is applied to the entire stage, the current passing through all stages is constant, so the amount of heat generated will differ for each stage depending on the width. Therefore, initially the entire thermochromic ink layer was colored, but as the voltage decreases, the colored parts of the thermochromic ink layer disappear step by step starting from the side corresponding to the wider width. become.

With this shape, the color development of the temperature-indicating ink layer 4 can be made to disappear step by step from both terminal portions, and finally disappear at the stage 22X.

The protective layer 5 is a layer that protects the conductive layer 2 from bending of the battery checker and from friction and corrosion of the conductive layer 2. Therefore, this protective layer 5 having breakage resistance, flexibility, cushioning properties, slip properties, etc. is effective against deterioration of the conductive layer 2. Furthermore, if the protective layer 5 is formed so as to cover the thinned portion of the conductive layer 2 that has been patterned, it is more effective against disconnection and damage of the conductive layer 5.

The pattern layer 3 may be formed as characters or symbols for appropriate purposes such as explaining how to read the color display of the temperature-indicating ink layer 4 or marking a scale.

The heat generating portion was formed between the terminal portions with three levels of thickness such that the width decreased by 4 mm every 10 mm in the direction between the terminal portions. A remaining amount scale is printed on the other side of the base film, and an ink containing a reversible temperature-indicating material made of thermochromic or chiral nematic liquid crystal is applied to the predetermined portions corresponding to each stage of the heat generating section. It was dried and allowed to change color at 40°C. When I checked the remaining voltage level of the AA batteries using this battery checker, I found that on the first day of use, the temperature of the heating part at the widest stage was 4.
When the temperature dropped below 0°C, the coloring of the temperature-indicating ink layer disappeared, and it was easy to see that there was only about one day's worth left. In fact, on the second day, the temperature of the second thickest heating part fell below 40°C and the coloring there disappeared. At this stage I could easily recognize that it was time to replace the battery.
