Abstract
A door opening and closing device has a rotational mechanism configured to switch a door between a closed position and an open position relative to a base member. The door opening and closing device includes a latch mechanism for latching the door in the closed position on the base member. The latch mechanism includes a latch device attached to the base member, a case disposed above the latch device, a slider slidably situated in the case above the latch device, and a latching member pivotally supported by the case and including a base end slidably connected with the slider and a tip configured to engage a portion of the door. When the door is moved to the closed position, the slider is moved by the door and is engaged with the latch device while the latching member is pivoted to engage the door.
