The device includes an insertion unit having at least a volume smaller than an interior volume of a cup and a shape in which a lower end portion of the insertion unit comes in contact with a bottom portion of the cup when inserted into the cup. The insertion unit includes a first magnet sealed in a bottom portion of the insertion unit. The device also includes an outer fixed unit to be placed under the cup. The outer fixed unit includes a second magnet sealed in the upper portion of the outer fixed unit for interacting with the first magnet of the insertion unit and securing the insertion unit to the cup by a magnetic force between the magnets. ## Claims ### Claim 1 A device for adjusting the capacity of a beverage cup, comprising: an insertion unit having at least a volume smaller than an interior volume of a cup and a shape in which a lower end portion of the insertion unit comes in contact with a bottom portion of the cup when inserted into the cup, the insertion unit comprising a first magnet sealed in a bottom portion of the insertion unit; and an outer fixed unit configured to be placed under the cup, the outer fixed unit comprising a second magnet sealed in the upper portion of the outer fixed unit for interacting with the first magnet of the insertion unit and securing the insertion unit to the cup by a magnetic force between the magnets. ### Claim 2 (depends on 1) The device of claim 1, wherein the insertion unit is made of a transparent or opaque material. ### Claim 3 (depends on 1) The device of claim 1, wherein the outer fixed unit comprises: a sensor configured to sense a movement of the cup; a CPU configured to receive a signal indicating movement of the cup from the sensor and outputting an alarm generation signal when receiving two consecutive signals from the sensor within a threshold time; and a display unit configured to generate an alarm by an output of the alarm generation signal from the CPU. ### Claim 4 (depends on 1) The device of claim 1, wherein the outer fixed unit comprises: a sensor configured to sense a weight; a CPU configured to accumulate weight values that increase when a signal is received from the sensor indicating added weight, and output an accumulated weight value; and a display unit configured to display an output of the CPU indicating the accumulated weight value. ### Claim 5 (depends on 1) The device of claim 1, wherein the outer fixed unit comprises: an input unit configured to receive user input indicating information of an alcoholic beverage; a sensor configured to sense a weight; a CPU configured to accumulate weight values that increase when a signal is received from the sensor indicating added weight, calculating an actual amount of alcohol consumed based on the accumulated weight value and the user information of the alcoholic beverage, and outputting the actual amount of alcohol consumed according to the information of the alcoholic beverage input from the input unit with respect to the accumulated weight values; and a display unit configured to display an output of the CPU indicating the actual amount of alcohol consumed. ### Claim 6 (depends on 1) The device of claim 1, further comprising an alcohol measurement sensor configured to measure an alcohol content of the alcoholic beverage, wherein the outer fixed unit comprises: a sensor configured to sense a weight of the alcoholic beverage; a CPU configured to accumulate weight values that increase when a signal is received from the sensor indicating added weight, calculating an actual amount of alcohol consumed based on the accumulated weight value and the measured alcohol content, and outputting the actual amount of alcohol consumed with respect to the accumulated weight value; and a display unit configured to display an output of the CPU.
