Description

[Detailed description of the invention] The present invention provides a packaging case equipped with a battery consumption prevention device, and more specifically, a battery that has a clock function, such as an electronic desk calculator with a clock (hereinafter referred to as a clock calculator). The present invention relates to a packaging case equipped with a battery consumption prevention device for storing an electronic device having a battery consumption prevention device during the inventory period of the driving electronic device.

An electronic device will be explained below using a calculator with a clock as an example.

In recent years, the power consumption of various electrical components in electronic devices such as calculators has become smaller, making it possible to create calculators that do not require battery replacement for a long period of time.

Therefore, the battery is assembled into the calculator body and shipped without a battery cover.

In the case of a calculator that has a power switch that can be turned on and off, battery consumption during the inventory period can be prevented by shipping the calculator with the power switch in the off state.

However, in the case of calculators with a clock, the clock is always displayed, so if the power is turned off by mistake, the clock information will be incorrect, so to prevent the power from being cut off, it is common to not have a power switch. It is.

Therefore, if a product is shipped with a built-in battery, there is a risk that the battery will be exhausted before it reaches the final consumer (user).

In order to prevent battery consumption, conventional methods as shown in FIGS. 1 and 2 have been used.

FIG. 1 shows a calculator with a clock equipped with a display DIS and a group of input keys KEY, and inside the upper case 4 and lower case 5 are a circuit board 2 and a battery that supplies power to the circuit board 2. 1 is stored.

(See Figure 2).

An insulating sheet 3 is inserted between the power terminal provided on the circuit board 2 and one pole of the battery 1, and one end 3'
comes out from between the upper case 4 and lower case 5 of the calculator with a clock.

Since the battery 1 is pressed onto the field board 2 by the spring contact 6, the insulating sheet 3 will not normally come off unless you hold 3' in your hand and pull it out, thereby reducing the consumption of the batteries in stock. is prevented.

When the calculator is delivered to a consumer and used for the first time, the battery 1 is brought into contact with the power terminal on the print 2 via the contacts 6 by pulling out the insulating sheet 3.

By doing this, the calculator with a clock becomes ready for operation.

However, with this conventional method, it takes time for the consumer to pull out the insulating sheet, and it also requires a component (insulating sheet) that is completely unrelated to the original function of a calculator with a clock, which increases the cost of the product. There were drawbacks.

Therefore, the present invention was made in view of the above points, and it is possible to reliably prevent battery consumption while in stock, and furthermore, it is equipped with a clock that allows the power supply to be easily turned on when it is delivered to the consumer's hands. It is an object of the present invention to provide a packaging case equipped with a battery consumption prevention device capable of preventing battery consumption of electronic equipment.

Next, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

According to the present invention, as shown in FIG. 3, an insulating tongue piece 7' is formed integrally with the packaging case 7 that houses the calculator with a clock to prevent battery consumption.

This insulating tongue piece 7' is used to connect one pole of the battery 9 and the power terminal of the circuit board 10 when tightening the upper case 8a and lower case 8b of the clock calculator 8 with screws as shown in FIG. inserted in between.

After that, the upper case 8a and the lower case 8b are tightened with screws or the like, and the housing is stored in the packaging case 7 with the lower case 8b facing down.

This situation is illustrated in FIG. When the clock calculator 8 stored in the packaging case is delivered to a consumer after battery consumption is prevented in this way, the clock calculator 8 is removed from the packaging case 7, but at that time the insulating tongue piece 7' Since the clock is removed from the calculator 8, power is supplied from the battery 1 through the power terminal of the circuit board, and the functions of the calculator with a clock begin to operate.

As described above, according to the present invention, there is no need to pull out the insulating sheet as in the conventional method, and since the insulating tongue piece 7' is formed integrally with the packaging case 7, the number of parts can be reduced, compared to the conventional method. This has the effect of reducing manufacturing costs.
