0) and the auxiliary power source mounting part (11) are covered by individual lids (12), (13), and each of these lids (12), (13) is itself. Of 2
Individual engaging pawls (14), (15) and screws (16), (1
7) and is fixed by one of the lids (1
When 2) or (13) is removed, only the covered battery (1) or (2) can be removed.

[0005]

However, both batteries (1) and (2) can be structurally simultaneously removed in any of the devices. For example, the device operating battery (1) can be removed.
There is a danger that the memory protection battery (2) will be completely removed and replaced at the same time, and in that case, there will be a serious problem that the stored contents of the memory will be lost. In addition, in any of the devices, it is possible to cover even after forgetting to install a new battery after removing the battery (1) or (2) when replacing the battery, and even in this case, the battery remains. The stored contents of the memory will be lost when the battery is exhausted. Moreover, when replacing the battery, a tool for removing and installing the screws (3), (8), and (17) is required, and there is a drawback that complicated removal work is required.

Therefore, according to the present invention, only one of the two types of batteries can be attached and detached, and the other battery cannot be attached and detached unless a new battery is attached, and the battery can be easily operated without any tools. It is a technical object to provide a battery mounting device having a configuration capable of quickly attaching and detaching the battery.

[0007]

As a technical means for achieving the above object, the present invention has a battery mounting device configured as follows. That is, in a battery mounting device that stores a device operation battery and a memory protection battery in an electrically connected state in the main power source mounting portion and the auxiliary power source mounting portion, respectively, the main power source mounting portion and the auxiliary power source mounting portion are simultaneously provided. A battery lid to be covered is rotatably provided, and a single battery insertion / removal hole that selectively fits each power supply mounting portion is formed in the battery lid by rotation. Each of them has an elastic body that normally holds the battery pressed by the lid in an electrically connected state to the battery terminal and inserts the battery insertion / removal hole into the hole when the battery insertion / removal hole is aligned with the power source mounting portion. It is characterized in that it is provided with a biased battery holder.

Further, in a battery mounting device for accommodating a device operation battery and a memory protection battery in an electrically connected state in the main power source mounting portion and the auxiliary power source mounting portion, respectively, the main power source mounting portion and the auxiliary power source mounting portion. A battery lid is provided rotatably at the same time, and a single battery insertion / removal hole is formed in the battery lid, which is selectively fitted to each power supply mounting portion by rotation, and each power supply is attached. In the mounting part,
It is also possible to provide a battery terminal formed of an elastic conductor that is inserted into the hole by a restoring force when the hole for inserting and removing the battery is aligned with the power source mounting portion.

[0009]

In normal operation, the battery lid is positioned such that the battery insertion / removal holes are spaced apart from any power supply mounting portion, and the battery is pressed by the battery lid in each power supply mounting portion to electrically connect to the battery terminals. In addition, each power supply mounting portion is covered by a single battery cover. Then, for example, when the device driving battery is replaced due to exhaustion, if the battery lid is rotated and the battery insertion / removal hole is aligned with the main power source mounting portion, the lid covering of the main power source mounting portion is released. Therefore, in the former device, the battery holding portion that holds the battery is pushed up into the battery insertion hole by the urging force of the elastic body such as the spring, and the battery is automatically pushed out. Then
The battery terminal extends into the battery insertion / removal hole by the restoring force of itself and pushes out the battery. In this state, the rotation of the battery lid is prevented by inserting the battery holding portion or the battery terminal into the battery insertion / removal hole. Therefore, it is possible to surely prevent forgetting to install the battery, and the battery lid does not rotate unless a new battery is installed in the main power supply installation part, and there is a single battery insertion hole for the two types of battery installation parts. Therefore, the two types of batteries cannot be taken out at the same time. That is, if you also want to replace the memory protection battery next time, insert a new battery into the main power supply mounting part and push down the battery holding part or the battery terminal with the battery below the battery lid to insert or remove the new battery. Insert the battery into the main power supply unit and insert the main power supply unit into the electrical connection state to rotate the battery cover, then align the battery insertion / removal hole with the auxiliary power supply unit and follow the same procedure as above. Replace the memory protection battery.
