Description

[Detailed Description of the Invention] This invention enables the battery to be replaced in an electronic device using a battery, such as a dry cell, without stopping the operation of the electronic device.

That is, in the case of an electric clock using dry batteries, the clock stops every time the battery is replaced, and the clock must be set correctly again, which is troublesome.

Also, when recording with a tape recorder using a battery, if the battery runs out and must be replaced, recording must be temporarily stopped, and important recording may become impossible. There is.

In such a case, the present invention is designed to allow battery replacement without stopping the operation of these electronic devices.

The following drawings illustrate this invention using three batteries 1a.

A case will be described in which lb and IC are connected in series.

In this invention, these batteries (hereinafter referred to as main batteries) 1
Main switches 2a, 2 for a, 1b, and IC, respectively.
b and 2C are connected in series to form a series circuit 3a.

3b and 3C, and further connect these to each other in series,
Auxiliary switches 4a, 4b, 4C and 5a are provided at both ends of each of these series circuits 3a, 3b, 3C, respectively.
.

5b, 5C so that the common auxiliary batteries 6 can be connected in parallel, and in connection with the operation of removing one of the main batteries, for example 1a, from a predetermined position, the removed main battery 1
While turning off the main switch 2a corresponding to a,
A pair of auxiliary switches 4a and 5a corresponding to the main battery 1a are respectively turned on.

For this reason, each of the main batteries 1a, 1b, and I
Storage parts 8a, 8 that individually store a, 1b, and IC
b.

8C, and the common auxiliary battery 6 can be similarly stored in an independent storage section 9.

FIG. 2 shows the storage section 8a for the battery 1a, and 10a is the battery 1a.
A contact point 10 is in contact with the positive terminal, and 10 b is a contact point in contact with the negative terminal, which is usually formed of a coil spring.

In order to switch the switches 2a, 4a, and 5a when the main battery 1a is attached or removed, for example, the above-mentioned triple switches 2a, 4a, and 5a are installed at the bottom of the storage section 7a.
Attach a switch device 11a having a
2 is controlled by attaching and detaching the main battery 1a, and is configured to perform switching control.

Although such a switch device 11a is well known,
A detailed explanation thereof will be omitted.

The storage parts 8b and 8C are similarly constructed.

In such a configuration, each main battery storage section 8a, 8b is now
, 8C, respectively, all the main switches and auxiliary switches are in the state shown in FIG. A voltage is obtained by connecting a, 1 b, and IC in series.

For example, if the main batteries are dry batteries each having a voltage of 1.5V, a voltage of 4.5V can be obtained in this example.

If you want to replace these main batteries 1a, 1bj C with new batteries, please use the auxiliary battery (new batteries are acceptable).
6 in the auxiliary battery storage section 9, one of the main batteries (for example, la) is removed (see FIG. 3).

In such a case, switches 2a, 4a, and 5a are the first
Switching from the state shown in the figure, terminal 13a - auxiliary switch 4a
-Auxiliary battery 6-Auxiliary switch 5a-Main switch 2b-Main battery 1b-Main switch 2C-Main battery LC - Terminal 13b A series circuit is formed, with the auxiliary battery 6 replacing the main battery 1a. is completed, terminals 13a-13b
Since almost a predetermined voltage can be obtained between the two, the electronic device can be used continuously.

Thereafter, by storing a new main battery 1a in the storage portion 8a, the state shown in FIG. 1 is returned again, and the electronic device can be used continuously in the same manner.

Next, the auxiliary battery 6 is stored in the auxiliary battery storage part 9. When the main battery 1b is removed from the storage part 8b in the same manner as described above, the switches 2b, 4b, and 5b are switched, and the auxiliary battery 6 is now the main battery. It will be in a state where it has been replaced with 1b.

When a new main battery 1b is stored in this storage portion 8b, the circuit shown in FIG. 1 is again formed.

In the same way, by finally replacing the main battery 1C, all batteries will be replaced with new ones, and during this time terminal 1
Normal voltage is always available between 3a and 13b, so electronic equipment has the feature of uninterrupted battery replacement.

Moreover, according to this invention, one auxiliary battery 6 is sufficient, and therefore, for electronic equipment, in addition to the storage part that stores the main battery, it is sufficient to provide a storage part that can store one auxiliary battery. have

In the above description, a case has been described in which three main batteries are used, but it is clear that the present invention is not limited to this.
