Abstract: The present invention discloses a UV sterilization fresh-keeping box, including an accommodating box and a UV sterilization device removably disposed on a top side of the accommodating box. The accommodating box includes a box body with a storage space, and a lid disposed on the box body. The lid has a light transmission part to allow UV light to pass through, and a first assembling part disposed on a peripheral side of the light transmission part. The UV sterilization device includes a case, a UV module disposed in the case, a control module electrically connected to the UV module, and a second assembling part disposed on a bottom side of the case. The UV sterilization device is mounted onto the lid by combining the second assembling part with the first assembling part. The UV module is controlled by the control module to emit UV light towards the light transmission part, so as to sterilize the storage space.

Abstract: A safe sterilization unit includes a bearing portion, a light source portion and at least one safety switch. The bearing portion includes two surfaces corresponding to each other; the light source portion is configured to generate sterilization light, and is disposed on one surface of the bearing portion; and the safety switch is disposed on one side surface, provided with the light source portion, of the bearing portion, and is connected with the light source portion. The safety switch is disposed to sense light to generate a sensing message, and to regulate power supply of the light source portion according to the sensing message.

Abstract: An image scanning method is applied in an image scanning device which includes an input tray and a paper feeding sensor. The method detects whether there are papers on the input tray in step one. If there are papers, step two is executed. Otherwise, the method ends and an error is reported. In step two, papers are separated and fed. Whether the papers contact the paper feeding sensor is detected in step three. The method executes step four if the papers contact the paper feeding sensor, and ends the method with an error message otherwise. In step four, the method scans and detects whether an image of a fed edge of each of the papers is abnormal. If the image is abnormal, the method ends and an error is reported. Otherwise, scanning continues.
