The present invention relates to an apparatus for detecting a state that a base material of a coffee vending machine is sold out, including: a base material container (10) having an openable and closeable cover (15); a weight (21) in the lower end of the cable (24) supported to the cover; and a detection means (20) generating a signal by tension of the cable (24), caused by the weight (21), thereby detecting an exhaustion state of a base material in the manner of receiving a sensor at a location spaced from the base material inside the base material container mounted in the coffee vending machine to prevent a concern about malfunction and a reduction in durability. |
