Description
Technical field
The present invention relates to a kind of black board teaching auxiliary devices, belong to teaching field.
Background technique
With being kept reforming to education, the education of students must increasingly be paid close attention to by people.On classroom, teacher
It is not possible that exhaustive looks after each student to the degree of understanding of knowledge, need to be reviewed in time under students class.It is past
Cause students cannot be timely by under relevant knowledge record, after class too much toward the knowledge point lectured on classroom by teacher
It cannot effectively review, seriously affect the learning efficiency of student.
Summary of the invention
The purpose of the present invention is to provide a kind of black board teaching auxiliary devices, right under the premise of guaranteeing that teacher normally gives lessons
Content on blackboard is scanned and records, and is played back after class by content of the projector to scanning, avoids attending class because of teacher
Excessive velocities and cause student not record the case where taking down notes.
Technical scheme is as follows to achieve the above object:
A kind of black board teaching auxiliary device includes electronic control unit (1), projector (2), synchronizer (3), blackboard eraser (4), rises
Bar (5), blackboard (6), inductive layer (7), pedestal (8), switch (9), scanner (10) drop；It is characterized in that, the synchronizer (3)
One end blackboard eraser (4) are installed, the other end of synchronizer (3) installs scanner (10), and synchronizer (3) is mounted on elevating lever (5)
On, vertical motion is done under the effect of contraction of elevating lever (5)；The inductive layer (7) and blackboard (6) are combined together, inductive layer
(7) for incuding the writing signal on blackboard (6)；The scanner (10) is used to scan on inductive layer (7) and comes from blackboard (6)
On writing signal simultaneously pass through scanner (7) by induction come writing signal be transferred in electronic control unit (1), electronics control
The writing signal that scanner (10) scans is transferred on projector (2) by unit (1) processed.When pressing lower switch (9), scanner
(10) vertical motion is done downwards simultaneously along elevating lever (5) under the action of synchronizer (3) with blackboard eraser (4), in scanner
(10) and blackboard eraser (4) move downward during writing signal in scanner (10) scanning inductive layer (7) on blackboard (6)
Simultaneously by scanner (7) by induction come writing signal be transmitted in electronic control unit (1)；Blackboard eraser (4) is transported downwards
The writing on blackboard is wiped in dynamic process；When synchronizer (3) reaches bottommost along elevating lever (5), blackboard eraser
(4) and scanner (10) also moves to blackboard (6) bottom together, while scanner (10) completes entire scanning process, scanner
(10) all writing signals of scanning are all transmitted in electronic control unit (1)；Blackboard eraser (4) is by all writings on blackboard
It is wiped.When pressing lower switch (9) again, scanner (10) and blackboard eraser (4) are under the action of synchronizer (3) along lifting
Bar (5) does vertical motion simultaneously upwards, and scanner (10) does not work during the motion, and blackboard eraser (4) is during the motion again
It is secondary that blackboard is cleaned, stop fortune when synchronizer (3), blackboard eraser (4) and scanner (10) reach blackboard (6) top
It is dynamic.Student can pass through projector (2) by the content that electronic control unit (1) scans scanner (10) whenever necessary after class
It launches on blackboard (6), the leakage detection taken down notes after class is filled a vacancy.
Advantages of the present invention:
1, scanner (10) moves under the action of synchronizer (3) simultaneously with blackboard eraser (4), it is ensured that the knowledge point on blackboard
Do not omit.
2, the knowledge point that scanner (10) scans is stored in electronic control unit (1), can be with when in need
When by projector (2) release, not by time restriction.
Detailed description of the invention
Fig. 1 is a kind of teaching auxiliary device top view of the present invention.
Fig. 2 is a kind of teaching auxiliary device left view of the present invention.
Specific embodiment
1, electronic control unit；2, projector；3, synchronizer；4, blackboard eraser；5, elevating lever；6, blackboard；7, inductive layer；8,
Pedestal；9, it switchs；10, scanner.
It is described further below with reference to attached drawing is implemented.
As shown in Figure 1 and Figure 2, a kind of black board teaching auxiliary device include electronic control unit 1, projector 2, synchronizer 3,
Blackboard eraser 4, elevating lever 5, blackboard 6, inductive layer 7, pedestal 8, switch 9, scanner 10；It is characterized in that, the one of the synchronizer 3
End installation blackboard eraser 4, the other end of synchronizer 3 install scanner 10, and synchronizer 3 is mounted on elevating lever 5, in elevating lever 5
Vertical motion is done under effect of contraction；The inductive layer 7 and blackboard 6 are combined together, and inductive layer 7 is used to incude the word on blackboard 6
Mark signal；The scanner 10 is used to scan the writing signal on blackboard 6 on inductive layer 7 while passing through scanner 7 will
The writing signal that induction comes is transferred in electronic control unit 1, and the writing signal that electronic control unit 1 scans scanner 10 passes
It is defeated on projector 2.When pressing lower switch 9, scanner 10 and blackboard eraser 4 under the action of synchronizer 3 along elevating lever 5 simultaneously
Vertical motion is done downwards, scanner 10, which scans, during scanner 10 and blackboard eraser 4 move downward comes from blackboard on inductive layer 7
Writing signal on 6 simultaneously by scanner 7 by incude come writing signal be transmitted in electronic control unit 1；Blackboard eraser 4 exists
The writing on blackboard is wiped during moving downward；When synchronizer 3 reaches bottommost along elevating lever 5, blackboard
Wiping 4 and scanner 10 also move to 6 bottom of blackboard together, while scanner 10 completes entire scanning process, and scanner 10 will be swept
All writing signals retouched all are transmitted in electronic control unit 1；Blackboard eraser 4 wipes all writings on blackboard.When
When pressing lower switch 9 again, scanner 10 and blackboard eraser 4 do vertical fortune along elevating lever 5 under the action of synchronizer 3 upwards simultaneously
Dynamic, scanner 10 does not work during the motion, and blackboard eraser 4 during the motion again cleans blackboard, works as synchronizer
3, stop motion when blackboard eraser 4 and scanner 10 reach 6 top of blackboard.Student can pass through electronic control whenever necessary after class
The content that unit 1 scans scanner 10 is launched by projector 2 onto blackboard 6, and the leakage detection taken down notes after class is filled a vacancy.
The embodiment of the present invention is described above, without departing from the principle and spirit of the present invention, can carry out
Modification, replacement and deformation.
