FIELD: detectors.
SUBSTANCE: in accordance with one implementation variant, the beverage preparing machine includes a beverage pouring apparatus, a cup placement area located under the beverage pouring apparatus, a light source configured to transmit light through a section of the cup placement area, and a receiver configured to receive at least part of the light transmitted by the light source. The processor determines whether the transparent cup is sufficiently inserted into the cup placement area, or whether said cup is at the required height, by detecting either a recess in the level of intensity of part of the light received by the receiver, or an inverted recess in the level of intensity of the light transmitted by the light source. After determining that the transparent cup is insufficiently inserted or is not at the required height, the processor prevents the spilling of the beverage from the beverage pouring apparatus.
EFFECT: ensured detection of a transparent cup.
