Description

The present invention relates to a structure for storing a battery of an electronic device using a dry battery or a rechargeable battery as a power source.

Some electronic devices driven by power supplied from a dry battery or a rechargeable battery use a cylindrical dry battery or a rechargeable battery (hereinafter referred to as a cylindrical battery). Some cylindrical batteries have different diameters and lengths, such as single type (R20 in Japanese Industrial Standards (JIS)), single type (same, R14), and single type (same, R6). To do. Therefore, when the battery storage unit of the electronic device has a structure that can store only one type of cylindrical battery, the capacity of the cylindrical battery stored in the battery storage unit is lost, and a cylindrical battery of the same size is stored. If not, the electronic device cannot be used.

Among such electronic devices, especially in disaster prevention radio receivers installed in homes that receive disaster prevention radio from municipalities, there is no replacement cylindrical battery, and emergency broadcasts regarding disasters such as earthquakes and heavy rain with disaster prevention radio receivers It becomes a big problem that it becomes impossible to receive. In order to solve such a problem, it is possible to reduce a risk that the disaster prevention radio cannot be received by providing a battery storage unit that can use cylindrical batteries of different sizes in an electronic device.

Moreover, it has the 1st holding member provided in the battery storage part so that rotation was possible in the up-down direction, and has the 2nd holding member provided in the battery cover so that rotation was possible up and down.

  The battery housing part is provided with a first holding part for holding the single battery and a second holding part for holding the single battery. Further, the battery lid is provided with a first pressing part for pressing the single battery and a second pressing part for pressing the single battery. A first storage area for storing the single battery is formed by the first holding part and the first pressing part. In addition, a second storage area for storing the single battery is formed by the second holding part and the second pressing part. Furthermore, a region for storing the AA batteries is formed by the first holding member and the second holding member moved to the first storage region.

  The battery storage unit described above stores the AA batteries in the region formed by the first holding member and the second holding member when the user uses the AA batteries. In addition, when the user uses a single battery or a single battery, the first holding member and the first holding member are rotated by rotating the first holding member and the second holding member in either the upper or lower direction. The single battery is stored in the first storage area formed by the above, or the single battery is stored in the second storage area formed by the second holding portion and the second pressing portion.

  Also, when a single battery is stored in the first storage area, it protrudes into the second storage area, and when a single battery or AA battery is stored in the second storage area, it protrudes into the first storage area. The simultaneous storage preventing member prevents the cylindrical batteries of different sizes from being stored at the same time.
