  In this beverage supply control process, the control unit 30 determines whether or not the container detection unit 24 has detected that the container C is in the beverage supply unit 22 (step S110). That is, the container detection unit 24 detects whether or not the container C is placed on the stage 22b. When it is detected that the container C is present (step S110, Yes), the control unit 30 determines whether the open / close door 23 is closed based on the detection result of the door open / close detection unit 26 (step S120). ). On the other hand, when it is not detected that the container C is present (step S110, No), the control unit 30 repeats the determination process of step S110.

  When the opening / closing door 23 is not closed in step S120 (step S120, No), the control unit 30 repeats the determination process in step S120. On the other hand, when the open / close door 23 is closed (step S120, Yes), the control unit 30 locks the open / close door 23 in the closed state using the door open / close lock mechanism 27 (step S150). A determination process is performed (step S140).

  FIG. 7 is a flowchart showing the contents of the container type determination process in FIG. In the container type determination process, the control unit 30 turns on the LED 29a constituting the light source unit 29 and drives the actuator 28b of the cover mechanism 28 (steps S141 and S142). Thereby, while the inside of the drink supply part 22 is irradiated to LED29a, the cover main-body part 28a rotates against the urging | biasing force of a cover spring, and the imaging surface 25a of the imaging part 25 is exposed. That is, the imaging unit 25 can perform imaging through the imaging opening 22e. The control unit 30 acquires image information read and generated through the imaging unit 25 (step S143).

  And the control part 30 reads the correspondence table 31a from the memory | storage part 31 through the container determination process part 30a (step S144), and determines the kind of container C by image information and the correspondence table 31a (step S145). More specifically, it is determined whether or not the shape of the container C in the digitized information digitized from the image information matches the digitized information in the correspondence table 31a, and the type of the matched container C is determined.

  The control unit 30 that has determined the type of the container C in this way stops driving the actuator 28b and turns off the LED 29a (step S146, step S147). Thereby, only the urging | biasing force of a cover spring acts and the cover main-body part 28a rotates and coat | covers the imaging surface 25a of the imaging part 25, and irradiation of the drink supply part 22 is complete | finished. And the control part 30 returns a procedure after that, and complete | finishes the determination process of the kind of this container.

  The control unit 30 that has performed the container type determination process in this manner displays, on the display unit 21, the beverage corresponding to the type of container C determined in step S140 described above, that is, the display of the beverage to be supplied. The guidance display for guiding the touch of the input unit 21a on which the confirmation word is displayed is performed (step S150).

  Thereafter, the control unit 30 determines whether or not the input unit 21a is touched (step S160). When the input unit 21a is not touched (No at Step S160), the control unit 30 repeats the determination process at Step S160. On the other hand, when the input unit 21a is touched (step S160, Yes), the control unit 30 causes the beverage generation unit 11 to perform the process of generating and supplying the beverage to be supplied (step S170). Thereafter, the control unit 30 determines whether or not the beverage supply by the beverage generation unit 11 is completed (step S180). If the beverage supply has not been completed (step S180, No), the control unit 30 returns to step S170 and continues the process of generating and supplying the beverage. On the other hand, when the beverage supply is completed (step S180, Yes), the control unit 30 unlocks the closed state of the open / close door 23 by the door open / close lock mechanism 27 (step S190), and then returns the procedure. Then, the current beverage supply control process is terminated.
