Title: Sheet weight-measuring device
Inventor: SENOO TOMONORI
IPC: B60N2/90
Filed: 2000-04-24
Abstract: PROBLEM TO BE SOLVED: To prevent a leaf spring mechanism from being broken by fatigue by minimizing stress being applied to the leaf spring for transmitting a load. SOLUTION: When a sheet load is applied to a bracket pin 3, the load is transmitted to a side arm 2 via a pin hole 2a. As a result, the side arm 2 is rotated with a base pin 4 as a center, and the load is transmitted to a Y arm 1 via a projecting part 1a of the Y arm 1 that is engaged to a long hole 2c. Since one end side of the Y arm 1 is restricted by the base pin 4, and the other is restricted by a sensor plate, a center lever is achieved and an upward load is applied to the center part for bending with both the end parts as a support and transmitting force in bending to the sensor plate. The Y arm 1 is a center lever. As a result, stress is dispersed, thus eliminating a part that is subjected to great stress, and hence increasing strength against fatigue fracture by repetitive load.
