The embodiment of the utility model provides a reading device, as shown in fig. 1 and 2, the reading device comprises a body 10, a shell 20, a camera 30 and an indicator light 40. The housing 20 is rotatably mounted at the rim of the body 10. In the case that the housing 20 rotates to the first position relative to the body 10, as shown in fig. 3 and 4, the camera 30 may be used for reading, and the visible light emitted by the indicator light 40 defines the guiding area a, where the guiding area a is located in the shooting area B of the camera 30. As shown in fig. 5, when the housing 20 is rotated to the second position with respect to the body 10, the camera 30 is in the housed state.

The body 10 is a main structure of the reader, and as shown in fig. 1, a housing 20 is provided at the center of the top of the body 10. The housing 20 is rotatable relative to the body 10. Optionally, the camera 30 and the indicator light 40 are both fixedly mounted to the housing 20. As the housing 20 rotates relative to the body 10, the camera 30 and indicator light 40 rotate therewith. As shown in fig. 4, the housing 20 rotates to a first position relative to the body 10, the camera 30 is located on the front surface of the body 10, and the camera 30 can capture an image of the object to be read downwards. At this time, the lens axis of the camera 30 forms a first angle with the front surface of the body 10, and the first angle is not greater than 180 °. As shown in fig. 5, the housing 20 is rotated to the second position with respect to the body 10, the camera 30 is in the stored state, and the indicator light 40 is rotated to the back of the body 10.

For example, the camera 30 rotates along with the housing 20, so that the central axis of the camera 30 is perpendicular to the back of the body 10, and the camera 30 can be used as a rear lens of the body 10. As another example, camera 30 rotates with housing 20 such that the center axis of camera 30 is perpendicular to the front of body 10. At this time, the camera 30 is used as a front lens of the body 10 for video or face recognition. For another example, the camera 30 rotates along with the housing 20 until the shooting direction of the camera 30 forms an obtuse angle with the front surface of the body 10, so as to shoot the object to be read, such as a human hand or a book.

When the housing 20 rotates to the first position relative to the body 10 and the indicator light 40 is turned on, as shown in fig. 3, the visible light emitted by the indicator light 40 defines a guiding area a, and the guiding area a is located in the shooting area B of the camera 30. According to the guidance of the indicator light 40, the user can quickly and accurately place the object to be read such as a book or a gesture in the effective identification area of the camera 30, so that the situation that the reading device cannot be used normally is avoided, and the use efficiency is improved. In practical applications, the guiding area a may be any shape such as a circle, a rectangle, etc. It should be noted that, the visible light emitted by the indicator light 40 may project the entire contour line of the guiding area a, or may project only a few key points or key line segments on the contour line, for example, the guiding area a is rectangular, and the indicator light 40 only indicates four corners of the rectangle. As long as the user can clearly know the guide area a defined by the user by means of the visible light emitted from the indication lamp 40.

In an alternative embodiment, the front of the body 10 of the reader is provided with a screen. In yet another alternative embodiment thereof, the reading device does not have a screen.
