[0036] Optical readers have a variety of application scenarios, and can be used in education, office environments, medical fields, and electronic reading. By magnifying and clearly displaying text, it helps users understand the contents of books, documents, labels, etc. more easily, and realizes the auxiliary reading function. Reading carriers have evolved from paper carriers to electronic carriers. Electronic carriers have more diverse needs in multimedia interaction. For example, during online teaching, the instructor and the user may need to interact online. The instructor can better understand the user's learning interests and learning status by observing the user's facial expressions. Users can better understand the teaching content by observing the instructor's facial expressions. However, optical readers magnify the content through reflection and refraction of light. In this process, the cameras on electronic carriers such as mobile phones and tablets usually cannot capture the user's facial image, which affects the teaching and interaction effects and reduces the user experience.

The interactive component 300 and the image acquisition component can include a camera, and the specific structure and model of the camera can be the same or different, and this application does not limit this.

[0050] In some embodiments of the present application, the optical reader may further include a controller, a processor, a communication module, a storage module and a power supply.

The input voltage specification of the power supply is adapted to the rated voltage of components such as the light source, the camera and the communication module.

[0051] In some embodiments of the present application, the first interactive component 300 includes a first camera, the image acquisition component includes a second camera, the optical reader also includes a camera adjustment component corresponding to the first camera and the second camera respectively, the first camera or the second camera is arranged on the corresponding camera adjustment component, and the camera adjustment component is used to adjust the position and rotation angle of the first camera or the second camera.

The camera adjustment component structures corresponding to the first camera and the second camera may be the same or different, and the present application does not limit this.

[0052] In some embodiments of the present application, the first camera is installed inside or outside the first interactive component.

[0053] In some embodiments of the present application, the second camera is arranged at a distance from the base within a range of 1 cm to 100 cm.

[0054] In some embodiments of the present application, the zoom-out magnification component includes at least one concave mirror. A concave mirror refers to a reflector with a curved surface whose surface shape is curved inward. When light is incident on the curved surface, the light reflected by the curved surface converges at the focus of the reflector. The extension line of the light allows the observer to see a positive virtual image, thereby achieving the purpose of magnifying the content on the reading carrier. The concave mirror has a small curvature radius, which makes it have a short focal length, which can meet the requirements of a more compact design and enhance the magnification effect of a specific target. By selecting a suitable concave mirror, the content on the reading carrier can be effectively magnified and the imaging quality can be improved.

[0055] In some embodiments of the present application, the curvature radius of the concave mirror ranges from 400mm to 600mm. The curvature radius determines the focal length of the concave mirror, that is, the distance from the mirror surface to the focus. By controlling the size of the curvature radius, the imaging effect can be controlled. For the optical reader in the present application, its main application scenario is desktop reading, and its length and width are between 300mm-400mm, and its height is between 500mm-600mm. When the curvature radius ranges from 400mm to 600mm, a better reading experience can be obtained.

[0056] In some embodiments of the present application, the collimating component 500 includes at least one semi-transparent and semi-reflective lens. When the zoom-out magnifying component is a concave mirror, the normal of the concave mirror is perpendicular to the reading carrier or is at a certain angle to the reading carrier. When the reading carrier is placed flat on the desktop, the user cannot directly observe the magnified reading content from the position of the window 200. Therefore, it is necessary to reflect the light to the position of the window 200 through the collimating component 500. The semi-transparent and semi-reflective lens can be arranged above the concave mirror and at a certain angle to the concave mirror, so that the user can observe the magnified reading content from the position of the window 200. The semi-transparent and semi-reflective lens and the concave mirror can be fixedly mounted on the fixed component 400, or they can have a certain degree of freedom, such as being rotatable, so as to adjust the imaging position to meet the usage needs of different users.

[0057] In some embodiments of the present application, the surface of the plane beam splitter is covered with a polarization beam splitter film, which can selectively reflect light in a specific direction, thereby reducing reflection loss and improving the efficiency of the optical system.

[0058] In some embodiments of the present application, the angle between the semi-transparent and semi-reflective lens and the incident light of the concave mirror ranges from 45° to 60°.

[0059] In some embodiments of the present application, the optical reader / writer further includes a light source, which is disposed on the base and is used to provide lighting for the reading carrier. The light source may be an LED lamp or a fluorescent lamp, and the number of light sources may be one or more. A plurality of light sources of different colors or brightness may be provided to meet the lighting requirements under different environmental conditions. The light source may be provided near the base 100 so that light may irradiate the reading carrier. When the reading carrier is a book or an electronic device without a backlight function, such as an ink screen reader without a backlight function, the light source may provide lighting so that the user can read normally under insufficient light conditions. If the ambient light is insufficient to meet the reading requirements, a light source may be provided outside the base 100 to meet the lighting requirements for reading.

[0060] In some embodiments of the present application, the optical reader / writer further includes a brightness adjustment component, which is electrically connected to the light source, and the brightness adjustment component is used to adjust the light intensity of the light source. Among them, the brightness adjustment component may include one or more of a knob, a button, a touch sensor or a remote controller. When the adjustment component is a remote controller, the wireless communication module and the receiver need to be integrated in the light source accordingly. When the light source is a fluorescent lamp, the brightness of the lamp can be changed by adjusting the resistance of the dimming resistor in the current circuit of the fluorescent lamp or adding a bidirectional thyristor component to the power supply circuit, and cooperating with the control circuit to control the current waveform. When the light source is an LED lamp, the ratio of the power-on time and the power-off time of the LED lamp can be changed by pulse width modulation (PWM), and the power supply of the LED can be quickly switched at a certain frequency to adjust the brightness of the light. The brightness can also be adjusted by adjusting the working current, working voltage or resistance value connected to the LED. The above brightness adjustment method or circuit can be implemented by existing technology and will not be repeated here.

[0061] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
