The 24 can be closed, and the inlet 24 can be opened when swinging forward in a manner of separating from the beverage supply unit 23.
　飲料供給部２３は、表示部２１の下方側に凹部を設けることにより構成してある。この飲料供給部２３は、ノズル２５、ステージ２６、後壁２７、側壁２８及び載置部２９を有している。 The beverage supply unit 23 is configured by providing a recess on the lower side of the display unit 21. The beverage supply unit 23 has a nozzle 25, a stage 26, a rear wall 27, a side wall 28, and a mounting unit 29.
　ノズル２５は、飲料生成部１１で生成された飲料を鉛直方向の下向きに吐出するものである。ステージ２６は、ノズル２５の下方域に設けてある。このステージ２６には、ノズル２５から吐出されてカップＣに供給されなかった飲料を通過させる通過孔２６ａが形成してあり、その下方には飲料を貯留するためのトレイ（図示せず）が設けてある。後壁２７は、ステージ２６の後面を覆うものである。側壁２８は、ステージ２６の両側面を覆うものである。 The nozzle 25 discharges the beverage produced by the beverage generation unit 11 downward in the vertical direction. The stage 26 is provided in the lower region of the nozzle 25. The stage 26 is formed with a passage hole 26a through which a beverage discharged from the nozzle 25 and not supplied to the cup C is passed, and a tray (not shown) for storing the beverage is provided below the passage hole 26a. There is. The rear wall 27 covers the rear surface of the stage 26. The side wall 28 covers both side surfaces of the stage 26.
　載置部２９は、図４に示すように、例えば樹脂材により成形したもので、左右一対となる態様で上方に向けて突出する取付片２９ａに形成された取付孔を貫通する揺動軸部材２９ｂが、側壁２８に架設されることで、揺動軸部材２９ｂの中心軸回りに揺動軸部材２９ｂとともに揺動可能に設けてある。 As shown in FIG. 4, the mounting portion 29 is formed of, for example, a resin material, and is a swinging shaft member that penetrates a mounting hole formed in a mounting piece 29a that projects upward in a paired manner on the left and right. Since 29b is erected on the side wall 28, it is provided so as to be swingable together with the swing shaft member 29b around the central axis of the swing shaft member 29b.
　この載置部２９は、底部２９ｃ及び後壁部２９ｄ，２９ｅを有している。底部２９ｃは、カップＣを載置させるためのものである。後壁部２９ｄ，２９ｅは、底部２９ｃに対して左右一対となる態様で互いに離隔した態様で設けてある。これら後壁部２９ｄ，２９ｅは、前方に向けて相互間隔が漸次増大するように設けてある。後壁部２９ｄ，２９ｅの間であって載置されるカップＣの後方には、開口部３０が形成されている。また、開口部３０の上部には、後壁部２９ｄ，２９ｅを連結する連結部２９ｆが設けられている。 The mounting portion 29 has a bottom portion 29c and rear wall portions 29d and 29e. The bottom 29c is for placing the cup C on it. The rear wall portions 29d and 29e are provided so as to be separated from each other in a pair of left and right with respect to the bottom portion 29c. The rear wall portions 29d and 29e are provided so that the mutual distance gradually increases toward the front. An opening 30 is formed behind the cup C placed between the rear wall portions 29d and 29e. Further, in the upper part of the opening 30, a connecting portion 29f for connecting the rear wall portions 29d and 29e is provided.
　載置部２９は、常態においては、図示せぬ付勢手段により付勢、あるいは自重により、図５に示すように底部２９ｃが前方に向かうに連れて漸次上方に傾斜する傾斜姿勢となるものである。載置部２９は、図５に示すように、底部２９ｃにホット飲料専用のカップＣが載置された場合にも傾斜姿勢を維持する。すなわち、載置部２９は、載置されたカップＣの内部が空の場合には傾斜姿勢となるものである。 In the normal state, the mounting portion 29 is in an inclined posture in which the bottom portion 29c gradually inclines upward as shown in FIG. 5 by urging by an urging means (not shown) or by its own weight. be. As shown in FIG. 5, the mounting portion 29 maintains an inclined posture even when a cup C dedicated to hot beverages is placed on the bottom portion 29c. That is, the mounting portion 29 is in an inclined posture when the inside of the mounted cup C is empty.
　ところで、図５に示したように、ホット飲料専用のカップＣが載置される場合、底部２９ｃはカップＣの底面に接している。また、後壁部２９ｄ、２９ｅは、互いに前方に向けて相互間隔が漸次増大するように設けてあるので、それぞれがカップＣの外周壁部の一部に接している。これにより、載置部２９は、カップＣを傾斜した姿勢で転動することを規制した状態で、つまり位置決めした状態で保持することができる。 By the way, as shown in FIG. 5, when the cup C dedicated to hot beverages is placed, the bottom 29c is in contact with the bottom surface of the cup C. Further, since the rear wall portions 29d and 29e are provided so that the mutual distance gradually increases toward the front of each other, each of the rear wall portions 29d and 29e is in contact with a part of the outer peripheral wall portion of the cup C. As a result, the mounting portion 29 can be held in a state in which the cup C is restricted from rolling in an inclined posture, that is, in a positioned state.
　載置部２９は、傾斜姿勢にある場合、水平面Ｇに対して傾斜角αで底部２９ｃが傾斜している。すなわち、ノズル２５が鉛直方向の下向きに飲料を吐出するので、載置部２９は、ホット飲料専用のカップＣの中心軸Ｃ１がノズル２５の吐出方向（鉛直方向）Ｈに対して後方に傾斜角α（２０°～４５°）で傾斜している。そして、傾斜角αで傾斜姿勢にある場合、ノズル２５から吐出される飲料がカップＣの内周壁部の任意個所に当接することを許容している。 When the mounting portion 29 is in an inclined posture, the bottom portion 29c is inclined at an inclination angle α with respect to the horizontal plane G. That is, since the nozzle 25 discharges the beverage downward in the vertical direction, the mounting portion 29 has an inclination angle of the central axis C1 of the cup C dedicated to the hot beverage to the rear with respect to the discharge direction (vertical direction) H of the nozzle 25. It is tilted at α (20 ° to 45 °). Then, when the beverage is in the inclined posture at the inclination angle α, the beverage discharged from the nozzle 25 is allowed to come into contact with an arbitrary portion of the inner peripheral wall portion of the cup C.
　載置部２９は、図６に示すように、底部２９ｃにコールド飲料専用のカップＣ、すなわち重量が予め決められた大きさ（例えば１００ｇ程度；以下、所定値ともいう）以上となるカップＣが載置された場合、カップＣの中心軸Ｃ１がノズル２５の吐出方向Ｈ（鉛直方向）に平行となる起立姿勢となるものである。また、載置部２９は、ホット飲料専用のカップＣの内部にノズル２５より飲料が投入される結果、投入量の増大に応じてカップＣの重量が所定値以上となる場合、カップＣの中心軸Ｃ１がノズル２５の吐出方向Ｈに平行となる起立姿勢となるものである。 As shown in FIG. 6, the mounting portion 29 has a cup C dedicated to cold beverages, that is, a cup C having a weight equal to or larger than a predetermined size (for example, about 100 g; hereinafter, also referred to as a predetermined value) on the bottom portion 29c. When mounted, the central axis C1 of the cup C is in an upright posture parallel to the discharge direction H (vertical direction) of the nozzle 25. Further, the mounting portion 29 is the center of the cup C when the weight of the cup C becomes equal to or more than a predetermined value as a result of the beverage being charged from the nozzle 25 into the cup C dedicated to the hot beverage.

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.
　扉開閉ロック機構３４は、飲料供給部２３の入口２４の近傍に設けてある。この扉開閉ロック機構３４は、入口２４を閉成する開閉扉２２が閉となる状態を保持させて、開閉扉２２が前方に向けて揺動することを規制するロック状態と、開閉扉２２が前方に向けて揺動することを許容する解除状態との間で択一的に切替可能なものである。扉開閉ロック機構３４の切り替えは、制御部４０から与えられる指令に応じて行われる。 The door opening / closing lock mechanism 34 is provided near the entrance 24 of the beverage supply unit 23.

Alternatively, it may be realized by using software and hardware together.
　制御部４０は、判定部４０ａを有する。制御部４０は、載置部２９にカップＣが載置された後、撮像部６０による撮像画像の撮像前に、撮像部６０内の撮像制御部６０ａに対して、撮像画像の撮像範囲内に延在部５１のみを映す補正枠内の補正用画像を撮像させ、補正用画像をもとに撮像画像の撮像に関するホワイトバランス調整及び露光調整を行わせる。その後、撮像制御部６０ａは、ホワイトバランス調整及び露光調整された状態で、少なくともカップＣを含む撮像画像を取得する。また、制御部４０は、撮像部６０による補正用画像及び撮像画像の撮像時に、光照射部６１，６２による光照射を行わせる。 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.
　図９は、撮像部６０によって撮像される撮像画像Ｄの一例を示す図である。図９に示すように撮像画像Ｄには、カップＣの画像領域ＤＣと延在部５１の画像領域Ｄ５１とが含まれる。補正用画像を取得するための補正枠Ｗは、延在部５１の画像である画像領域Ｄ５１のみを映す画像枠である。なお、撮像画像ＤをもとにカップＣのカップ種別を色情報や模様情報等によって判定する場合、カップＣの画像領域ＤＣ内の識別枠Ｗ１の画像を用いるようにする。 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.
　判定部４０ａは、姿勢検出部３２の検出結果が傾斜姿勢である場合、カップＣはホット飲料専用のカップであると分類し、姿勢検出部３２の検出結果が起立姿勢である場合、カップＣはコールド飲料専用のカップであると分類する判定を行い、さらに、撮像部６０が撮像した撮像画像をもとに、カップＣの飲料種別を判定する。 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 cold beverage-only cup, and further, the beverage type of the cup C is determined based on the captured image captured by the imaging unit 60.
＜飲料供給制御処理＞
　次に、図１０及び図１１に示したフローチャートを参照して制御部４０による飲料供給制御処理手順について説明する。 <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.
　図１０に示すように、制御部４０は、まず、カップ検出部３１によりカップＣが載置部２９に載置されたと検出されたか否かを判定する（ステップＳ１０１）。カップＣが有ると検出されない場合（ステップＳ１０１：Ｎｏ）には、本判定処理を繰り返す。 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.
　カップＣが有ると検出された場合（ステップＳ１０１：Ｙｅｓ）、制御部４０は、扉開閉検知部３３の検知結果をもとに、開閉扉２２が閉であるか否かを判定する（ステップＳ１０２）。開閉扉２２が閉でない場合（ステップＳ１０２：Ｎｏ）には、ステップＳ１０２の判定処理を繰り返す。 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.
　制御部４０は、開閉扉２２が閉である場合（ステップＳ１０２：Ｙｅｓ）には、カップ判定処理を行う（ステップＳ１０３）。 When the opening / closing door 22 is closed (step S102: Yes), the control unit 40 performs a cup determination process (step S103).
　その後、制御部４０は、表示部２１に対して、カップ判定処理で判定した種類のカップＣに対応した飲料、すなわち供給すべき飲料（ホットカフェラテ飲料又はアイスカフェラテ飲料等）の表示と、確認の文言が表示された入力部２１ａのタッチを案内する案内表示を行う（ステップＳ１０４）。 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).
　その後、制御部４０は、入力部２１ａがタッチされたか否かを判定する（ステップＳ１０５）。入力部２１ａがタッチされない場合（ステップＳ１０５：Ｎｏ）、制御部４０は、ステップＳ１０５の判定処理を繰り返す。一方、入力部２１ａがタッチされた場合（ステップＳ１０５：Ｙｅｓ）、制御部４０は、扉開閉ロック機構３４を用いて開閉扉２２を閉状態にロックし（ステップＳ１０６）、飲料生成部１１に対して、供給する飲料の生成及び供給の処理を行わせる（ステップＳ１０７）。 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).
　その後、制御部４０は、飲料生成部１１による飲料供給が終了したか否かを判定する（ステップＳ１０８）。飲料供給が終了していない場合（ステップＳ１０８：Ｎｏ）には、制御部４０は、ステップＳ１０７に戻って飲料の生成及び供給の処理を続行する。 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.
　一方、飲料供給が終了した場合（ステップＳ１０８：Ｙｅｓ）には、制御部４０は、扉開閉ロック機構３４による開閉扉２２の閉状態のロックを解除し（ステップＳ１０９）、本処理を終了する。なお、上記の処理は所定期間ごと繰り返し行われる。 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.
　図１１は、図１０に示したステップＳ１０３のカップ判定処理の処理手順を示すフローチャートである。図１１に示すように、制御部４０は、まず、姿勢検出部３２から姿勢検出信号の入力が有るか否かを判定する（ステップＳ２０１）。 FIG. 11 is a flowchart showing a processing procedure of the cup determination process in 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).
　姿勢検出信号の入力が有る場合（ステップＳ２０１：Ｙｅｓ）、制御部４０は、判定部４０ａを通じて載置されたカップＣがホット飲料専用のものと判定する（ステップＳ２０２）。 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).
　その後、撮像制御部６０ａは、光照射部６１，６２による光照射のもと、撮像部６０が補正枠Ｗ内の補正用画像、すなわち延在部５１の画像を取得し、撮像部６０に対するホワイトバランス調整及び露光調整の補正処理を行う（ステップＳ２０３）。その後、撮像制御部６０ａは、補正処理された状態の撮像部６０によって撮像画像Ｄを取得する（ステップＳ２０４）。 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).
　その語、判定部４０ａは、ホット飲料専用のカップＣに対し、撮像画像の識別枠Ｗ１内の画像をもとに、カップＣの色情報や模様情報などによってカップ識別を行い（ステップＳ２０５）、ステップＳ１０３にリターンする。 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.
　一方、姿勢検出信号の入力がない場合（ステップＳ２０１：Ｎｏ）、制御部４０は、判定部４０ａを通じて載置されたカップＣがホット飲料専用のものと判定する（ステップＳ２０６）。 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).
　その後、撮像制御部６０ａは、光照射部６１，６２による光照射のもと、撮像部６０が補正枠Ｗ内の補正用画像、すなわち延在部５１の画像を取得し、撮像部６０に対するホワイトバランス調整及び露光調整の補正処理を行う（ステップＳ２０７）。その後、撮像制御部６０ａは、補正処理された状態の撮像部６０によって撮像画像Ｄを取得する（ステップＳ２０８）。 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).
　その後、判定部４０ａは、コールド飲料専用のカップＣに対し、撮像画像の識別枠Ｗ１内の画像をもとに、カップＣの色情報や模様情報などによってカップ識別を行い（ステップＳ２０９）、ステップＳ１０３にリターンする。 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.
　本実施の形態では、カップＣの撮像画像を撮像する前に、延在部５１を撮像して撮像部６０のホワイトバランス調整及び露光調整を行うようにしているので、外乱光の影響を受けず、カップＣの色情報や輝度情報などを精度良く識別できるため、カップ識別精度を高めることができる。 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.
　また、光照射部６１，６２の光量は外乱光の光量よりも大きくしているため、この点からも、撮像画像の取得の際、外乱光の影響を受けず、カップ識別精度をさらに高めることができる。 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.
　なお、上記の実施の形態では、カップＣの載置ごとに、延在部５１の補正用画像をもとに、ホワイトバランス調整及び露光調整を行っていたが、ホワイトバランス調整は必要に応じて行うようにしてもよい。 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.
　また、光照射部６１，６２を設けず、光照射部６１，６２の光照射なしで、ホワイトバランス調整及び露光調整を行うようにしてもよい。 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.
　さらに、上記の実施の形態では、載置部２９を用いて、載置部２９に載置されたカップＣを傾斜状態あるいは起立状態にし、姿勢検出部３２が傾斜状態か起立状態かを検出することによって、カップＣがホット飲料専用のカップかコールド飲料専用のカップかを分類して判定するようにしていたが、載置部２９及び姿勢検出部３２を設けず、撮像画像のみによってカップ識別を行うようにしてもよい。 Further, in the above-described embodiment, the mounting unit 29 is used to bring the cup C mounted on the mounting unit 29 into an inclined state or an upright state, and the posture detecting unit 32 detects whether it 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.
＜変形例＞
　図１２は、変形例による補正用画像の補正枠Ｗ´を説明する説明図である。上記の実施の形態では、延在部５１の補正用画像をもとにホワイトバランス調整及び露光調整を行うようにしていたが、図１２に示すように、本変形例では、延在部５１の画像である画像領域Ｄ５１の一部、及び、カップＣの画像である画像領域ＤＣの一部のみを含む補正枠Ｗ´を形成し、この補正枠Ｗ´内の補正用画像を用いて、撮像部６０の露光調整を行うようにしている。なお、実施の形態と同様に、露光調整は、補正枠Ｗ´内の輝度平均を求めて補正する。また、カップＣのカップ識別は、識別枠Ｗ２内の画像をもとに行われる。 <Modification example>

The exposure of unit 60 is adjusted. As in the embodiment, the exposure adjustment is corrected by obtaining the brightness average in the correction frame W'. Further, the cup identification of the cup C is performed based on the image in the identification frame W2.
　本変形例では、カップ識別の対象であるカップＣの画像領域ＤＣが補正枠Ｗ´に含まれているため、安定した露光調整を行うことができる。 In this modification, since the image region DC of the cup C, which is the object of cup identification, is included in the correction frame W', stable exposure adjustment can be performed.
　なお、上記の実施の形態及び変形例では、いずれも標準反射率などの反射率をもつ延在部５１を用いるようにしていたが、これに限らず、延在部５１の表面に標準反射率などの反射率をもつパネルを別途配置するようにしてもよい。 In the above-described embodiments and modifications, the extending portion 51 having a reflectance such as the standard reflectance is used, but the present invention is not limited to this, and the standard reflectance is applied to the surface of the extending portion 51.
