It becomes a state and gives a posture detection signal to the control unit 40. On the other hand, when the mounting unit 29 is in the upright posture, the posture detecting unit 32 is turned off by interposing the detected unit 32c between the light emitting unit 32a and the light receiving unit 32b, as shown in FIG. , The output of the posture detection signal to the control unit 40 is stopped.

The door open / close detection unit 33 is provided in the vicinity of the inlet 24 of the beverage supply unit 23, and is composed of, for example, an optical sensor or the like. The door opening / closing detection unit 33 detects the opening / closing of the entrance 24 by the opening / closing door 22, and more specifically, detects whether or not the entrance 24 is closed, that is, the opening / closing door 22 is closed. .. The door open / close detection unit 33 gives the control unit 40 a detection result of whether or not the open / close door 22 is closed.

The door opening / closing lock mechanism 34 is provided in the vicinity of the inlet 24 of the beverage supply unit 23. The door opening / closing lock mechanism 34 holds a closed state of the opening / closing door 22 that closes the entrance 24, and regulates the opening / closing door 22 from swinging forward. It can be selectively switched between a release state that allows swinging forward. The door opening / closing lock mechanism 34 is switched according to a command given from the control unit 40.

The control unit 40 supplies electricity to the above-mentioned beverage generation unit 11, display unit 21, cup detection unit 31, posture detection unit 32, door open / close detection unit 33, door open / close lock mechanism 34, imaging unit 60, and light irradiation units 61 and 62. The operation of each of these units is comprehensively controlled according to the programs and data stored in the storage unit 41 which is also electrically connected.

The control unit 40 may be realized by, for example, a processing device such as a CPU (Central Processing Unit) executing a program, that is, by software, or by hardware such as an IC (Integrated Circuit). Alternatively, it may be realized by using software and hardware together.

The control unit 40 has a determination unit 40a. The control unit 40 is within the imaging range of the captured image with respect to the imaging control unit 60a in the imaging unit 60 after the cup C is mounted on the mounting unit 29 and before the imaging image is captured by the imaging unit 60. The correction image in the correction frame that reflects only the extending portion 51 is imaged, and the white balance adjustment and the exposure adjustment related to the imaging of the captured image are performed based on the correction image. After that, the image pickup control unit 60a acquires an image captured image including at least the cup C in a state where the white balance is adjusted and the exposure is adjusted. Further, the control unit 40 causes the light irradiation units 61 and 62 to irradiate light when the correction image and the captured image are captured by the image pickup unit 60.

FIG. 9 is a diagram showing an example of the captured image D captured by the imaging unit 60. As shown in FIG. 9, the captured image D includes an image region DC of the cup C and an image region D51 of the extending portion 51. The correction frame W for acquiring the correction image is an image frame that displays only the image area D51 that is the image of the extending portion 51. When determining the cup type of the cup C based on the captured image D based on color information, pattern information, or the like, the image of the identification frame W1 in the image area DC of the cup C is used.

The determination unit 40a classifies the cup C as a cup dedicated to hot beverages when the detection result of the posture detection unit 32 is an inclined posture, and when the detection result of the posture detection unit 32 is an upright posture, the cup C is classified as a cup dedicated to hot beverages. A determination is made to classify the cup as a cup dedicated to cold beverages, and further, a beverage type of the cup C is determined based on an image captured by the imaging unit 60.

<Beverage supply control processing>
Next, the beverage supply control processing procedure by the control unit 40 will be described with reference to the flowcharts shown in FIGS. 10 and 11.

As shown in FIG. 10, the control unit 40 first determines whether or not the cup detection unit 31 has detected that the cup C is mounted on the mounting unit 29 (step S101). If the presence of the cup C is not detected (step S101: No), this determination process is repeated.

When it is detected that the cup C is present (step S101: Yes), the control unit 40 determines whether or not the opening / closing door 22 is closed based on the detection result of the door opening / closing detection unit 33 (step S102). ). If the opening / closing door 22 is not closed (step S102: No), the determination process of step S102 is repeated.

When the opening / closing door 22 is closed (step S102: Yes), the control unit 40 performs a cup determination process (step S103).

After that, the control unit 40 displays and confirms to the display unit 21 the beverage corresponding to the type of cup C determined by the cup determination process, that is, the beverage to be supplied (hot cafe latte beverage, ice latte beverage, etc.). Guidance display for guiding the touch of the input unit 21a on which the wording is displayed is performed (step S104).

After that, the control unit 40 determines whether or not the input unit 21a has been touched (step S105). When the input unit 21a is not touched (step S105: No), the control unit 40 repeats the determination process of step S105. On the other hand, when the input unit 21a is touched (step S105: Yes), the control unit 40 locks the opening / closing door 22 in the closed state by using the door opening / closing lock mechanism 34 (step S106), and the beverage generation unit 11 is contacted. The beverage to be supplied is produced and supplied (step S107).

After that, the control unit 40 determines whether or not the beverage supply by the beverage generation unit 11 has been completed (step S108). If the beverage supply has not been completed (step S108: No), the control unit 40 returns to step S107 to continue the process of producing and supplying the beverage.

On the other hand, when the beverage supply is completed (step S108: Yes), the control unit 40 unlocks the closed state of the opening / closing door 22 by the door opening / closing lock mechanism 34 (step S109), and ends this process. The above process is repeated every predetermined period.

FIG. 11 is a flowchart showing a processing procedure of the cup determination process of step S103 shown in FIG. As shown in FIG. 11, the control unit 40 first determines whether or not there is an input of the attitude detection signal from the attitude detection unit 32 (step S201).

When there is an input of the posture detection signal (step S201: Yes), the control unit 40 determines that the cup C placed through the determination unit 40a is dedicated to the hot beverage (step S202).

After that, in the image pickup control unit 60a, under the light irradiation by the light irradiation units 61 and 62, the image pickup unit 60 acquires the correction image in the correction frame W, that is, the image of the extension unit 51, and whites the image pickup unit 60. The balance adjustment and the exposure adjustment correction processing are performed (step S203). After that, the image pickup control unit 60a acquires the captured image D by the image pickup unit 60 in the corrected state (step S204).

That word, the determination unit 40a identifies the cup C dedicated to the hot beverage based on the image in the identification frame W1 of the captured image based on the color information and pattern information of the cup C (step S205). Return to step S103.

On the other hand, when there is no input of the posture detection signal (step S201: No), the control unit 40 determines that the cup C placed through the determination unit 40a is dedicated to the hot beverage (step S206).

After that, in the image pickup control unit 60a, under the light irradiation by the light irradiation units 61 and 62, the image pickup unit 60 acquires the correction image in the correction frame W, that is, the image of the extension unit 51, and whites the image pickup unit 60. The balance adjustment and the exposure adjustment correction processing are performed (step S207). After that, the image pickup control unit 60a acquires the captured image D by the image pickup unit 60 in the corrected state (step S208).

After that, the determination unit 40a identifies the cup C dedicated to the cold beverage based on the image in the identification frame W1 of the captured image based on the color information and pattern information of the cup C (step S209), and steps. Return to S103.

In the present embodiment, before the captured image of the cup C is imaged, the extending portion 51 is imaged to adjust the white balance and the exposure of the imaging unit 60, so that the image is not affected by the ambient light. Since the color information and the brightness information of the cup C can be accurately identified, the cup identification accuracy can be improved.

Further, since the light intensity of the light irradiation units 61 and 62 is larger than the light intensity of the ambient light, from this point as well, the cup identification accuracy is further improved without being affected by the ambient light when acquiring the captured image. Can be done.

In the above embodiment, the white balance adjustment and the exposure adjustment are performed based on the correction image of the extending portion 51 for each placement of the cup C, but the white balance adjustment is performed as necessary. You may do it.

Further, the white balance adjustment and the exposure adjustment may be performed without providing the light irradiation units 61 and 62 and without the light irradiation of the light irradiation units 61 and 62.

Further, in the above embodiment, the mounting portion 29 is used to put the cup C mounted on the mounting portion 29 into an inclined state or an upright state, and the posture detecting unit 32 detects whether the posture detecting unit 32 is in an inclined state or an upright state. By doing so, it was determined whether the cup C was a cup dedicated to hot beverages or a cup dedicated to cold beverages, but the cup identification was performed only by the captured image without providing the mounting unit 29 and the posture detecting unit 32. You may do it.
