Claims 1 and 5 (equivalent to the claims in Chinese patent documents) state that "the above-mentioned signal receiving device mainly consists of a signal processing circuit and a camera connected with it, and the above-mentioned laser pen mainly consists of a head light-emitting element and a light-emitting point circuit", but due to the use of the expression "mainly", how the above-mentioned device is constituted is not clearly defined (that is, it is unclear and incomplete). Therefore, Claims 2, 4, 6 and 7 citing Claims 1 and 5 are not explicitly stated.
Claims 1 and 5 describe "correspondence", but they do not clearly describe what it is. Therefore, Claims 2, 4, 6 and 7 citing Claims 1 and 5 are not explicitly described.
Claim 5 states that "the synchronous signal transmitter associated with the laser emitting point is connected with the above signal processing loop", but it does not explicitly state that there are multiple "laser pointers" and what the connection is related to, and the "synchronous signal transmitter" is included in the laser pointer and signal receiving device, so Claim 5 and Claims 5 and 7 citing it are not explicitly stated.
2. The inventions described in all claims within the scope of patent claims in this application are easy to be invented by technicians with conventional knowledge in the technical field to which this invention belongs. Therefore, according to paragraph 2 of Article 29 of the Patent Law, this application cannot obtain a patent right.

Inventions cited (i.e. comparison documents): Registration License AnnouncementNo.10-0823313 (April/July, 2008).
The technical scheme invented in claim 1 relates to a synchronous laser pen electronic whiteboard system, which comprises a laser pen. The laser pen is composed of a signal receiving and processing device consisting of a synchronous signal receiver, a receiving and processing circuit and a camera, a synchronous signal transmitter, a head light-emitting component and a laser pen circuit, which corresponds to the LED lighting device including a synchronous input part, a camera and a laser pen part (see the abstract and attached drawings 1 ~ 3).
However, the invention that the laser pointer in claim 1 is synchronized with the signal receiving device and the camera is automatic is somewhat different in structure. In the cited invention, the LED lamp and laser pen are used to make the laser emit light for a certain period of time, and the user moves the lighting equipment to the position where the camera takes pictures while watching the laser pen. Therefore, ordinary technicians can obtain the structure of the automatic synchronization laser pen and signal receiving device invented in claim 1 by simply changing the synchronization state, so the invention in claim 1 is easy for ordinary technicians to invent based on reference.
The technical feature of the inventive accessory of claims 2-4 relates to a synchronous transmitter, which is a simple structure of the LED action pulse generating mechanism based on the invention.
The invention of claim 5 relates to a synchronous laser pen electronic whiteboard system, which comprises a synchronous signal receiver, a signal receiving device consisting of a receiving and processing circuit and a camera, a synchronous signal transmitter, a head light-emitting component and a laser pen circuit, and corresponds to the LED lighting device comprising a synchronous input unit, a camera and a laser pen (see abstract, figure 1-3).
However, the invention of claim 5 is somewhat different in structure, because the laser pointer is synchronized with the signal receiving device and the camera is automatic. In the cited invention, the LED lamp and laser pen are used to make the laser emit light for a certain period of time, and the user can move the lighting equipment to the position where the camera takes pictures while watching the laser pen. Therefore, ordinary technicians can obtain the structure for synchronizing the laser pointer and the automatic signal receiving device invented in claim 5 by simply changing the synchronization state. Therefore, the invention in claim 5 is based on the cited invention.
The inventions of claims 6 and 7 add a structure related to the synchronous transmitter, which is easily obtained based on the LED action pulse generation mechanism in the cited invention.
Therefore, the invention in claim 1-7 is easy for ordinary technicians to invent based on reference (that is, it is not creative). The ending.
