[Effect of the idea]

This invented charger allows you to easily remove the battery by sliding the ejection member sideways. It also has the advantage of being easy and quick to take out. That is, the removal member should be placed sideways. When it slides, the inclined surface of the ejection member presses the bottom of the battery and removes the battery from the storage compartment. This is because it can be made to stand out.

[0022] In addition, unlike conventional chargers, you can insert your fingers into both sides of the storage compartment to insert the battery. Does not require a recess to grab. The structure allows the removal member to slide sideways, making it easy to remove batteries. It can be taken out. For this reason, the width should be relatively narrow so that the battery can be removed smoothly. It has the advantage of being able to

[0023] Furthermore, the charger of this invention requires a recess at the bottom of the storage compartment to push the battery into. Not required. Therefore, there is no need to design the storage section deeply. At the bottom of the storage compartment, A space is required to install an ejection member that slides horizontally below the battery. deer However, as shown in Figure 1, the ejection member does not push the battery when it is inserted. There is no need to raise it, and the parts other than the slope can be designed to be considerably thinner. For this reason, this The invented charger also has the advantage of not being very thick overall.
