Abstract

A removable unit is for being connected and assembled to a main unit. An apparatus includes the removable unit and the main unit. The removable unit includes an outer housing portion and a base portion. The base portion includes a base body and a latch structure. The latch structure includes a fulcrum section, at least one latch section, a pressing section and a longitudinal section. The latch section is coupled to a latch corresponding section of the main unit, and the pressing section is exposed on an apparatus surface. When the pressing section is pressed by a user, a pressing stroke of the pressing section is greater than a latch stroke of the latch section. When the pressing stroke is greater than a pressing threshold stroke, the latch stroke is greater than a latch threshold stroke, and the removable unit is able to be removed from the main unit. Accordingly, it is advantageous in avoiding mis-unlocking by the user to mis-remove the removable unit from the main unit.
