PURPOSE:To enable free selection according to the purpose of inspection and measurement by accomplishing measurement of weight with a spring or the like and measurement of bulk with a photoelectric switch or the like simultaneously. CONSTITUTION:Springs 3 and 3' and 4 and 4' are provided between vertically mobile upper plate 1 and a fixed lower plate 2. There are arranged a recoil plate holder 5 adapted to freely adjust the height at one end in the center of the upper plate, spring seats 6 and 6' for recoil plates at one end in the center of the lower plate, a recoil plate spring 7, a base 8 for the recoil plates, a shaft 9 for the recoil plates, an adjustable recoil plate or stopper bars 10 and 10' and a recoil plate anchor shaft 22 for fixing the center of the recoil plates. The right and left ends of the recoil plates 10 and 10' are supported with recoil plate supports 11 and 11'. A switch mount plate 18 and a switch 19 capable of freely adjusting the position are also mounted on the upper plate 1 while a switch side plate 20 is mounted on the lower plate 2 to start transmission and recording of signals with the sliding of the switch 19. |
