Description

[Detailed description of the invention] This invention has two casings that can be opened and closed via a hinge etc., and each casing has independent functions such as a radio receiver and a game watch. This invention relates to a multi-purpose composite electrical device that includes electronic components.

BACKGROUND ART In combination-type composite electric equipment, such as a combination of a radio receiver and a game watch, batteries with different characteristics are generally used depending on the functions of the electronic components in each housing. Specifically, radio receivers use regular AA batteries or AAA batteries, and game watches use button batteries. This is because the electronic components of the game watch consume less power and the voltage changes relative to power consumption are constant. However, button batteries are sometimes difficult to obtain, especially depending on the region of export.
Since it is expensive, it is desired to take this situation into consideration and to make it possible to use the battery on the radio receiver side in common with the game watch. In that case, it is conceivable to simply connect the two electrical devices using a power cord, but it is not preferable to easily connect the two batteries when their characteristics are different. That is, if both electric devices are connected with the button battery still inserted, there is a risk that a backflow will occur from the button battery to the radio receiver side, resulting in a disadvantage that the button battery will be significantly consumed.

This idea was made in view of the above circumstances,
The purpose is to replace the inexpensive or easily available batteries used in one of two types of electrical equipment, each with independent functions, with the expensive or difficult-to-obtain batteries used in the other electrical equipment. It can be used as a substitute, and when connecting both electrical devices with a power cord, make sure that the battery of the electrical device being supplied cannot be connected without removing the battery of the electrical device that is being supplied, so that unexpected accidents caused by reverse flow of the battery should be avoided. An object of the present invention is to provide an electrical device characterized in that it prevents wear and tear.

Hereinafter, embodiments of this invention will be described based on the drawings.

FIG. 1 shows an example of the electrical device of this invention, which is a combination of a radio receiver and a game watch. In other words, this electrical equipment
It has a first casing 1 and a second casing 2 which are connected to each other so as to be openable and closable via the first casing 1, and the first casing 1 includes electronic components (not shown) for a radio receiver and its power supply. For example, an AA battery 3 is built-in, and on the other hand, the second housing 2 is built-in an electronic component for a game watch (not shown) and a button battery 4 as its power source. In this case, as shown in FIG. 2, the AA battery 3
A first jack 7 is disposed to be connected to the button battery 4 at the bottom of the second housing 2, and a cord 8 is connected to an electronic component for the game watch (not shown) in the storage area for the button battery 4 at the bottom of the second housing 2. A second jack 9 is provided. In addition, a battery cover 10 that is detachable from the second housing 2 is attached to the storing portion of the button battery 4, and a chamber 11 formed by the battery cover 10 and the second housing is attached. A button battery 4 is stored in the button battery 4.

On the other hand, reference numeral 12 denotes a power cord, at one end of which a first plug socket 13 is attached which is detachably connected to the first jack 7, and at the other end the second jack 9 is attached. A second plug socket 14 is attached to the second plug socket 14 to be detachably connected to the second plug socket 14. Power cord 1 configured like this
2 is used to operate the electronic parts on the game watch side using the AA battery 3 on the radio receiver side. In this case, as shown in FIG. The second jack 9 and the second plug socket 14 are not connected unless the button battery 4 of the body 2 is removed. Therefore, when using this power cord 12 to supply the voltage of the AA battery 3 on the radio receiver side to the electronic components on the game watch side, the button battery 4 on the game watch side must be removed, and the button Connect both electrical devices with the battery 4 installed, and connect the button battery 4.
There is no risk of consumption due to backflow of the battery, and the advantage is that the AA battery 3 on the radio receiver side can be used in common to enjoy game watching.

Note that although the above embodiment describes a composite electrical device that combines a radio receiver and a game watch, this combination does not necessarily have to be used; for example, an electrical device that uses AA batteries and a button battery may be used. Any combination of electrical equipment with different types of batteries may be used, such as a radio receiver and a calculator, a radio receiver and a clock, a radio receiver and a tape recorder, etc. A combination of these is possible.

As explained above, according to the electrical equipment of this invention, an inexpensive or easily available battery used in one of two types of electrical equipment, each having independent functions, can be used in the other electrical equipment. It can be used as a substitute for expensive or difficult-to-obtain batteries, and in addition, when connecting both electrical devices with a power cord, it is possible to connect them without removing the battery from the electrical device being supplied. The use value of the battery is remarkable because it provides excellent effects such as being able to prevent unexpected battery consumption due to backflow.

Claims (1)

[Scope of utility model registration request] An electrical appliance that has two housings connected through a connector such as a hinge, and each housing contains electronic components that have independent functions and a battery that is the power source for driving the electronic components. In the device, one of the first cases includes a first jack connected to a battery in the first case;
A second jack connected to the electronic components in the second housing is disposed in the battery storage section of the other second housing, and a power source having a plug socket that is detachably connected to each of the jacks. When using the power cord to operate the electronic components in the second housing using the battery voltage in the first housing, the power cord must be connected to the plug socket of the power cord unless the battery in the second housing is removed. An electrical device characterized in that connection to a jack in a second casing cannot be made.
