大なるものである。 [Detailed Description of the Invention] The present invention relates to a charger for a cylindrical storage battery, such as an alkaline storage battery, which makes it possible to charge a large storage battery and a small storage battery with the same charger. An embodiment of the present invention will be described below based on the drawings. Reference numeral 1 designates a charging base, on one side of which is formed a first storage section 3 for storing a large (for example, AA type) storage battery, and on the other side for storing a small (for example, AA type) storage battery.
A second storage section 4 is formed to store a storage battery. Furthermore, these storage sections 3 and 4 are communicated so that when a storage battery is stored in one, a portion of the storage battery is exposed to the other, thereby preventing storage batteries of different sizes from being charged at the same time. 5 is a common cathode contact piece that contacts the cathodes of the large and small storage batteries stored in the storage parts 3 and 4;
Reference numerals 6 and 7 are anode contact pieces that contact the anodes of the large storage battery and the small storage battery, respectively, and are connected to a resistor that regulates the charging current value according to the capacity of the storage battery in contact. 8 in the figure is a code. 2 is a charging circuit component, and a gap 9 is formed on the back surface of the first storage section 3 based on the difference in longitudinal dimension in the relationship between the first storage section 3 and the second storage section 4.
Built-in. In the charger of the present invention having such a structure, when charging a large storage battery, the large storage battery 10 is stored in the first storage part 3 as shown in FIG. 3, and when charging a small storage battery, the charger As shown in Figure 4, the small storage battery 2
0 is stored in the second storage section 4,
Each can be charged at a predetermined charging current value. As described above, according to the present invention, a first storage part for storing a large storage battery and a second storage part for storing a small storage battery are formed on both sides of the charging base, and a second storage part for storing a small storage battery is formed on both sides of the charging base. 1. By cleverly utilizing the void formed on the back side of the storage section and incorporating the charging circuit components into this void, we are able to provide a charger that can charge storage batteries of different sizes with a simple structure. This greatly contributes to the miniaturization of the device.
