Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted" and "connected" are to be interpreted broadly, e.g., as being either fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

As shown in fig. 1 to 5, an embodiment of the present invention provides a learning machine 100, which includes a housing, a display screen assembly 103 is disposed at an upper end of the housing, a circuit board assembly electrically connected to the display screen assembly 103 is disposed inside the housing, a camera 401 (shown by a dotted line in fig. 4) with a downward lens is disposed below the circuit board assembly, the camera 401 is electrically connected to the circuit board assembly, and the camera 401 is located at a central portion of the housing; the lower extreme of casing is equipped with two landing legs 201, and two landing legs 201 are relative to be located the left and right sides of camera 401, and the width of landing leg 201 in the fore-and-aft direction is 20-30 mm, and the distance of the preceding terminal surface of landing leg 201 and camera 401 axis 406 equals the distance of the rear end surface of landing leg 201 and camera 401 axis 406.

Based on the scheme, when the learning machine 100 is used, the supporting legs 201 slide on the paper surface of the book, the camera 401 reads characters on the paper surface, the width of the supporting legs 201 in the front-back direction is set to be 20-30 mm, the distance between the front end surfaces of the supporting legs 201 and the central axis 406 of the camera 401 is equal to the distance between the rear end surfaces of the supporting legs 201 and the central axis 406 of the camera 401, and when the front end surfaces or the rear end surfaces of the supporting legs 201 reach the edge of the book or the middle seam of the book, it can be guaranteed that the central cursor of the camera 401 located in the central position can still point to the most marginal characters.

It should be understood that, in general, pages of a book have a certain margin, left and right pages of the book have an outer margin and an inner margin, and the length of the margin is the distance between the text at the edge and the edge of the page. If the margin is large and the legs are narrow, the learning machine 100 can align the cross cursor at the center of the screen with the characters at the edges of the page at any margin position. As seen in fig. 4, the above object can be achieved as long as half b of the leg width W is not less than the inner pitch. Usually, the inner distance is about 10mm, and the characters have certain width, so that b is 10-15 mm. In other words, a leg width of 20-30 mm is suitable.

In this embodiment, as shown in fig. 1 to 4, the casing includes an upper casing 101 and a lower casing 102, the learning machine 100 further includes a power/confirmation key 104, a volume up/down key 105, a function key 106 (hidden opposite side, not shown), a TYPE _ C socket 107, a leg 201, a speaker sound release hole 202, an eject button 203, and an LED light supplement lamp set 204, and of course, the inside of the casing further includes electronic components such as a CPU and a memory.

Specifically, when the learning machine 100 of the present embodiment is used in a video real-time word-grabbing translation application, the leg 201 is automatically ejected by the ejection contact 301 when the ejection button 203 on the back side is pressed. The user continues to open the legs 201 by hand and the legs 201 will be locked in a stable state by the positioning mechanism in a position perpendicular to the lower body shell 102. The learning machine 100 further comprises a positioning blade 302 positioned on the supporting leg 201, a clamping groove notch 303 used for positioning is formed in the positioning blade 302, and a dustproof lens 304 is arranged below the camera 401.

As shown in fig. 4, after the legs 201 are opened, the user can slide on the book paper like using a magnifying glass with the learning machine 100 of the present embodiment held by the user. As seen in fig. 4, the bottom end face of leg 201 directly contacts paper 403, and the bottom end face of leg 201 makes paper 403 just above the object image focal plane of inner camera 401. Thus, the captured image on the paper surface 403 can be dynamically displayed on the display screen assembly 103 in real time without focusing at any time during use.

FIG. 5 shows an image displayed on display screen assembly 103, including image display area 501, paraphrase display area 504, and status indication area 505. A cross cursor 502 is drawn at the center of the image display area 501. If there is exactly a word (word or Chinese character) at the center cross cursor 502, the word will be "grabbed" and changed to the complementary color display, such as the black display area 503 in FIG. 4, indicating that the grabbed word is "way". At the same time, a simple paraphrase for the captured word way is displayed in the upper paraphrase display area 504. If necessary, pressing the confirmation key may instead display the detailed explanation full screen. Therefore, the word-grabbing translation in reading is real-time, and the word-grabbing translation is obtained in a visible mode and is very convenient.

The performance of the camera 401 is very important for the purpose of dynamically capturing words in real time by the learning machine 100 of the present embodiment. Because the longest length of the English word can reach 30mm, and the longest length of the combination of the phrases can reach 50mm, the horizontal shooting width of the learning machine 100 should reach 50-70 mm. Because the height of the legs 201 is substantially the subject distance of the camera 401, the subject distance of the camera 401 cannot be too large, otherwise the user experience will be poor due to the taller legs 201. Experiments show that the object distance of the camera 401 is more suitable in the range of 20-40 mm. Such a camera with a large viewing angle and a short object distance has a large shooting area and cannot be significantly distorted, and the requirement on the camera 401 is high.

As seen in fig. 4, since the camera 401 is disposed at the center of the lower case 102, the battery 404 (shown in dotted lines) can be disposed only at the front or rear of the lower case 102, which results in a heavy weight of the learning machine 100 when standing on the paper. Therefore, a weight metal block 405 (shown by a dotted line in fig. 4) should be provided at the other side of the lower case 102 opposite to the camera.

To sum up, the width of the leg 201 in the front-back direction is set to be 20-30 mm, and the distance between the front end surface of the leg 201 and the central axis 406 of the camera 401 is equal to the distance between the rear end surface of the leg 201 and the central axis 406 of the camera 401, so that when the front end surface or the rear end surface of the leg 201 reaches the edge of a book or the middle seam of the book, it can be ensured that the center cursor of the camera 401 located in the center can still point to the edge-most character.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
