The stirring barrel body has an opening. The receiving structure has a bean-through opening and an observation opening. The image capturing assembly has at least one image capturing device and a reflective surface which is disposed in the capturing scope of the at least one image capturing device and is tilted facing the at least one image capturing device and the observation opening. Therefore, the at least one image capturing device can capture an image inside the receiving structure through the reflective surface and the observation opening. Another bean roasting apparatus with an image capturing assembly is provided, wherein at least one image capturing device of the image capturing assembly can capture an image inside the receiving structure through the observation opening directly. ## Claims ### Claim 1 A bean roasting apparatus for beans, comprising: a stirring barrel body, comprising an opening; a receiving structure, disposed on a side of the stirring barrel body, and comprising a bean-through opening and an observation opening, wherein the bean-through opening is connected to the opening; and an image capturing assembly, disposed on a side of the receiving structure and comprising at least one image capturing device and a reflective surface which is disposed within a capturing scope of the at least one image capturing device and is tilted to face the at least one image capturing device and the observation opening; wherein the at least one image capturing device is configured to capture an image inside the receiving structure through the reflective surface and the observation opening; wherein the receiving structure further comprises an inclined or curved surface towards the stirring barrel body and connected to the bean-through opening, so that some of the beans can be continuously and temporarily received in the receiving structure through the opening of the stirring barrel body and the bean-through opening, and then slide downward and return back into the stirring barrel body through the bean-through opening and the opening of the stirring barrel body while the beans are roasting. ### Claim 2 (depends on 1) The bean roasting apparatus of claim 1, wherein the image capturing assembly further comprises a light emitting device facing the observation opening and configured to illuminate the inside of the receiving structure through the observation opening. ### Claim 3 (depends on 2) The bean roasting apparatus of claim 2, wherein the image capturing assembly further comprises a housing structure, the at least one image capturing device, the reflective surface and the light emitting device are disposed within the housing structure. ### Claim 4 (depends on 3) The bean roasting apparatus of claim 3, wherein the housing structure comprises a first opening and a second opening, the reflective surface facing the observation opening through the first opening and the light emitting device facing the observation opening through the second opening. ### Claim 5 (depends on 4) The bean roasting apparatus of claim 4, wherein the image capturing assembly further comprises two transparent components which are disposed at the first opening and the second opening respectively. ### Claim 6 (depends on 5) The bean roasting apparatus of claim 5, wherein the transparent component disposed at the second opening is glass or plastic. ### Claim 7 (depends on 5) The bean roasting apparatus of claim 5, wherein the image capturing assembly further comprises two sealing components which are disposed between the two transparent components and the housing structure respectively. ### Claim 8 (depends on 1) The bean roasting apparatus of claim 1, wherein the image capturing assembly further comprises a housing structure, the at least one image capturing device and the reflective surface are disposed within the housing structure. ### Claim 9 (depends on 8) The bean roasting apparatus of claim 8, wherein the housing structure comprises a first opening, and the reflective surface faces the observation opening through the first opening. ### Claim 10 (depends on 8) The bean roasting apparatus of claim 8, wherein the image capturing assembly further comprises a heat sink which is disposed on the housing structure. ### Claim 11 (depends on 1) The bean roasting apparatus of claim 1, wherein the image capturing assembly further comprises at least one protective lens which is disposed in front of the at least one image capturing device. ### Claim 12 (depends on 1) The bean roasting apparatus of claim 1, wherein the image capturing assembly is movably or detachably disposed on a side of the receiving structure. ### Claim 13 (depends on 12) The bean roasting apparatus of claim 12, wherein the image capturing assembly comprises a sliding component and a rotating component. ### Claim 14 (depends on 1) The bean roasting apparatus of claim 1, further comprising at least one microphone which is disposed on a side of the stirring barrel body. ### Claim 15 A bean roasting apparatus for beans, comprising: a stirring barrel body, comprising an opening; a receiving structure, disposed on a side of the stirring barrel body, and comprising a bean-through opening and an observation opening, wherein the bean-through opening is connected to the opening; and an image capturing assembly, disposed on a side of the receiving structure, and comprising at least one image capturing device, wherein the observation opening is disposed within a capturing scope of the at least one image capturing device, and the at least one image capturing device is configured to capture an image inside the receiving structure through the observation opening directly; wherein the receiving structure further comprises an inclined or curved surface towards the stirring barrel body and connected to the bean-through opening, so that some of the beans can be continuously and temporarily received in the receiving structure through the opening of the stirring barrel body and the bean-through opening, and then slide downward and return back into the stirring barrel body through the bean-through opening and the opening of the stirring barrel body while the beans are roasting. ### Claim 16 (depends on 15) The bean roasting apparatus of claim 15, further comprising a heat sink which is disposed on a side of the image capturing device.
