Claims

[Claims for Utility Model Registration] 1. A pressing device in a thickness measuring device that measures the thickness of a workpiece on a workpiece mounting table 1a by pressing a gripper 2 disposed above the workpiece, comprising: A rotation amount enlarging mechanism 30 that enlarges and transmits the amount of rotation of the rotating shaft 3 to which the gripper 2 is attached;
A pressing device in a thickness measuring device, which is provided with a rotation measuring meter 6 for measuring the amount of rotation. 2. The amount of rotation of the rotating shaft 3 to which the gripper 2 is attached is measured by a rotation meter driven by the rotation amount enlarging mechanism 30, and the electrical signal at this time is stored in the memory circuit A, 10, 16, and then, The data obtained by adding the thickness tolerance by the calculation circuits 11 and 17 is stored in the memory circuits B, 12 and 18, and this data is compared with the data sequentially sent from the latch circuits 9 and 15 to the judgment circuits 13 and 19.
A thickness discriminating device in a thickness measuring device that compares the thickness and outputs an over or under NG signal when the thickness is outside the tolerance.
