Description of the Invention: [Technical Field] The present invention relates to a measuring apparatus, and more particularly to a measuring apparatus for performing flatness measurement. [Prior Art] In the process of injection molding and baking of the front and back cover of the notebook computer, the plane yield is large;; it is the difficulty of the control of such a process, and the degree of deformation of the plane is straight = the product f of the product is printed. Measurement is especially important. ^: The method of measuring is to stand the test panel on the side of the fixture, the test panel is close to the upper and lower edges, and the two locating pins are attached from the θ * tight / α, The position of the gap is determined whether the flatness conforms to the specification plate::; the gap between the reference surface of the fixture and the fixture is determined to be in contact with the reference surface of the fixture, and the positioning method is inconvenient and the measurement is inconvenient. The result is not quantified, if it needs to be matched with the thickness gauge measurement, that is, by the thickness (4) of the insertion gap to help define, this method has low measurement efficiency and large measurement error. [Invention content]: It is necessary to provide an easy measurement and The flatness measuring device with accurate measurement results, and the flatness measuring device for measuring the flat type of the component to be tested, including the platform for supporting one side of the device to be tested, the bracket of the platform, and one for A measuring system that measures the flatness of the component to be tested and is placed at the appropriate position of the bracket. The measuring system includes a measuring instrument. I. 5, f. The measuring table of the elastically telescopic crown and the control unit. Τ The adjusting component's one end of the measuring portion abuts against the appearance of the measuring meter, and tightens the fine tuning component to push the measuring portion to move toward the object to be tested to contact the component to be tested, and The table # abutting against the measuring portion is also elastically extended toward the direction to be measured, and the measuring table displays the moving distance of the measuring portion according to the length of the crown extending, thereby measuring the flatness of the device to be tested.
