Title: IMAGE ACQUISITION DEVICE AND APPARATUS FOR MAKING A BEVERAGE, COMPRISING SAID IMAGE ACQUISITION DEVICE
Abstract:
An image acquisition device (4) for a capsule, usable in an apparatus (1) for making a beverage that uses the capsule. The device (4) comprises an optical sensor (42) facing an image capture zone (40) in which said capsule is located or passes, at least one light emitting element (44) for lighting the image capture zone (40), a box-shaped casing (5) surrounding an inner chamber (50) in which the optical sensor (42) is housed. The box-shaped casing (5) comprises a front wall (51), that is made of transparent material and is interposed between the optical sensor (42) and the image capture zone (40), and lateral walls (52, 53, 54, 55) that are connected to the front wall (51) and laterally delimit the inner chamber (50). At least one lateral wall (52) of the box-shaped casing (5) is coupled to the light emitting element (44) and has a lighting surface region (521) that is outside the inner chamber (5) and is facing the image capture zone (40), the lateral wall (52) being a light guide designed to transmit, inside it, the light emitted by the light emitting element (44) to said lighting surface region (521). The image capture zone (40) is lit by light projected from the lighting surface region (521) of the light-guide lateral wall (52).
