Abstract: The counter contains a counting member with a rotational shaft extended from the counting member; a base member for positioning the counting member with the rotational shaft extended outside the base member; a cover member with an opening that is jointed to the base member to house the counting member in between and to expose the digits of the counting member by the opening; and a pressing member sleeving over the rotational shaft for engaging the counting member. The counter is structurally simple, convenient to use, not powered by a battery, and of a lower production cost.
