Abstract

(57) [Abstract] [Purpose] To enable use of both dry batteries and rechargeable batteries in electronic equipment without preparing a casing for accommodating dry batteries. [Structure] A battery box 3 provided at a required position of an electronic device main body 2 has a shape into which a dry battery 4 can be directly loaded,
The battery pack 7 containing the rechargeable battery 6 has a shape that can be loaded into the battery box, and the dry battery and the rechargeable battery can be exchanged, which improves usability and reduces the shape of the battery box for storing the battery. ..

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a battery power source used as a power source for an electronic surveying instrument used outdoors or various portable electronic devices.

[0002]

[Prior Art]

 As a power source for electronic surveying instruments used outdoors or various portable electronic devices, there are dry batteries or rechargeable batteries represented by nickel-cadmium batteries.

Conventionally, in many of the electronic devices, both a dry battery and a rechargeable battery can be used. In order to be able to use both dry and rechargeable batteries, a battery box for storing dry batteries and rechargeable batteries is required on the side of the electronic device, which is generally economical or compact. With one battery box, dry batteries and rechargeable batteries can be selectively stored in the same battery box. In order to selectively store dry batteries and rechargeable batteries in the same battery box, the shape of the battery pack that is a set of multiple batteries or batteries in the stored condition must be the same for dry batteries and rechargeable batteries. I have to.

Therefore, a required number of dry batteries are housed in a casing so that they can be handled as a battery pack, and the shape of a battery pack containing a rechargeable battery is the same as that of the casing.

[0005]

[Problems to be solved by the device]

 However, when comparing dry batteries of equivalent capacity to rechargeable batteries, rechargeable batteries are smaller, so if you try to put both types of batteries in the same battery box, the battery box will contain the dry batteries. The shape is enlarged to fit the casing. Further, since this casing has to be prepared separately, there is a problem such as an increase in cost.

In view of the above situation, the present invention relates to a battery pack of an electronic device that can be used for both dry batteries and rechargeable batteries without preparing a casing for accommodating dry batteries. Is.

[0007]

[Means for Solving the Problems]

 According to the present invention, the shape of the battery box provided at the required position of the electronic device body is such that the dry battery can be directly loaded, and the battery pack containing the rechargeable battery can be loaded into the battery box. It is characterized in that it can be replaced with a battery.

[0008]

[Action]

 Dry batteries and rechargeable batteries can be selected appropriately according to the situation, improving usability, and because the dry batteries can be directly loaded, the shape of the battery box can be made small, and a casing for packing the dry batteries is not required. is there.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

In this embodiment, a laser measuring machine will be described in which a laser is emitted in a horizontal direction and is rotated about a vertical line to form a measurement reference plane by the laser.

The measuring machine main body 2 contains a rotatable laser projector 1, and a battery box 3 is provided below the measuring machine main body 2. The battery box 3 is formed so that the required number of dry batteries 4 can be directly loaded, and a contact is provided on the back surface of the lid 5 that closes the battery box 3 so that the dry batteries 4 can be stored in the battery box 3. By closing the lid 5 in this state, the dry batteries 4 are connected in parallel or in series so that they can be fed with power.

Next, a case where the above-mentioned laser measuring machine uses the battery pack 7 having the rechargeable battery 6 built therein as a power source will be described.

The outer shape of the battery pack 7 is the same as the battery storage space of the battery box 3. Since the rechargeable battery 6 is smaller than the dry battery 4, the battery pack 7 that houses the rechargeable battery 6 can have the same shape as the battery housing space as described above. A contact point (not shown) capable of contacting the contact point formed inside the battery box 3 is provided on the front end surface of the battery pack 7. Further, a charging connector 8 for charging the rechargeable battery 6 is provided at a required position of the battery pack 7.

By loading the charged battery pack 7 into the battery box 3, it is possible to supply power to the measuring device body 2. Further, as described above, since the dry battery 4 is directly loaded into the battery box 3, the shape of the battery box 3 is the minimum shape capable of accommodating the dry battery 4.

The rechargeable battery 6 can be charged by connecting it to a household power source via the charging connector 8.

Therefore, both the dry battery and the rechargeable battery can be appropriately selected and used according to the situation.

Although the laser measuring machine has been described in the above embodiment, it goes without saying that the invention can also be applied to other electronic devices.

[0018]

[Effect of the device]

 As described above, according to the present invention, both dry batteries and rechargeable batteries can be used, the battery storage space can be minimized, and a casing for packing dry batteries is not required. Therefore, it has an excellent effect of reducing the cost.
