Abstract

The invention relates to the field of control equipment, in particular to a trackball brief report table, which comprises an outer shell which is hollow in the internal portion, wherein a mounting cavity is formed in the outer shell; an operation assembly which is used for sensing the operation of an operator and sending an operation signal and comprises a cursor adjusting piece, wherein the cursor adjusting piece is installed on the outer shell, and the cursor adjusting piece is provided with an operation part exposed out of the outer shell and a signal transmission part located in the outershell; and a control module which is mounted in the mounting cavity and is used for receiving an operation signal and sending the operation signal to an external receiver so as to realize movement ofa cursor. Compared with the prior art, the trackball brief report table has the advantages that the cursor is controlled by arranging the cursor adjusting part, so that an operator can control the external receiver conveniently, and compared with the prior art that only front-back page turning of PPT can be achieved, the PPT page turning device is wider in use occasion and easier and more convenient to operate.
