Description
Technical field
The present invention relates to instructional device field, and in particular to a kind of education and instruction equipment.
Background technology
In modern teaching, it is often necessary to the manuscript of boss is scanned and recognized on classroom and forms editable text immediately
Original text.Such as Application No.：201520328339.4, the existing scanning to manuscript uses area array CCD, and polylith area array CCD is solid side by side
One overall face recognition unit of composition on one piece of bottom plate is scheduled on, the height of face recognition unit is adjusted by being arranged on side
Knucle-gear and handle drives, using unilateral handle drives, there are problems with for it：Unilateral handle drives side Knucle-gear rotates,
Since polylith area array CCD face battle array is larger, during moving up and down, its balance is unstable, easily makes polylith area array CCD both sides
Translational speed is uneven, influences to use.
The content of the invention
In order to solve the above-mentioned technical problem the present invention provides a kind of education and instruction equipment.
The present invention is achieved through the following technical solutions：
A kind of education and instruction equipment, including area array CCD, be located at the supporting rack at area array CCD both ends, be arranged on supporting rack
Pinion and the first Knucle-gear being meshed respectively with pinion, the second Knucle-gear, further include what is be meshed with the second Knucle-gear
3rd Knucle-gear, first Knucle-gear, the 3rd Knucle-gear are socketed in shaft and are socketed with adapting rod in two shafts,
Two adapting rods are parallel and two adapting rods between be connected with operation lever.First Knucle-gear, the 3rd knuckle-tooth of this programme
Adapting rod is socketed with the shaft of wheel, drives adapting rod to rotate by operation lever, since two adapting rods are parallel to each other and the
Commutation of two Knucle-gears to rotation direction, it is ensured that the Knucle-gear at area array CCD both ends rotates synchronous, guarantee area array CCD both ends shifting
Dynamic synchronism, improves stability and balance that area array CCD is adjusted.
Preferably, for the ease of the operation to operation lever, handle is vertically and fixedly provided with the operation lever.
Further, the handle is arranged on the midpoint of operation lever.
Preferably, in order to avoid supporting rack departs from Knucle-gear, the bottom of support frame as described above is provided with limiting device.
Further, the limiting device is limited block.
Preferably, in order to make adapting rod not influence to operate, the angle between the adapting rod and Knucle-gear is more than 30 degree
And less than 60 degree.
Compared with prior art, the present invention have the following advantages and advantages：
1st, the present invention synchronizes area array CCD both ends driving, improves stability and balance that area array CCD is adjusted.
Brief description of the drawings
Attached drawing described herein is used for providing further understanding the embodiment of the present invention, forms one of the application
Point, do not form the restriction to the embodiment of the present invention.
Fig. 1 is the structure diagram of the present invention.

Embodiment 1
A kind of education and instruction equipment as shown in Figure 1, including area array CCD 1, be located at the supporting rack 2 at 1 both ends of area array CCD, set
The first Knucle-gear 31, the second Knucle-gear 32 put the pinion 4 on supporting rack 2 and be meshed respectively with pinion 4, further include
The 3rd Knucle-gear 33 being meshed with the second Knucle-gear 32, first Knucle-gear 31, the 3rd Knucle-gear 33 are socketed in shaft 5
Be socketed with adapting rod 6 in upper and two shafts 5, two adapting rods 6 are parallel and two adapting rods 6 between be connected with behaviour
Make bar 7.First Knucle-gear 31, the second Knucle-gear 32, the specification of the 3rd Knucle-gear 33 are identical.
Handle 8 is vertically and fixedly provided with the operation lever 7.
The handle 8 is arranged on the midpoint of operation lever 7.
The bottom of support frame as described above 2 is provided with limiting device 9.
The limiting device 9 is limited block.
Angle between the adapting rod and Knucle-gear is more than 30 degree and less than 60 degree.
Above-described embodiment, has carried out the purpose of the present invention, technical solution and beneficial effect further
Describe in detail, it should be understood that the foregoing is merely the embodiment of the present invention, be not intended to limit the present invention
Protection domain, within the spirit and principles of the invention, any modification, equivalent substitution, improvement and etc. done, should all include
Within protection scope of the present invention.
