Front flip type

Compared to the slider cover type, this type has improved workability and size disadvantages. By occupying the cover that falls to the card side, it has a mechanism to hold down the card. As mentioned above, it has superiority in terms of size and workability, and is now being used more than the slider cover type. On the other hand, there are issues with the holding power when the card is tilted upwards, and if a strong holding power is required, it may be avoided.
