Problems solved by technology

[0006] However, if Figure 2B In the conventional technical means shown, its overly complex elastic structure 17 (a group of meandering metal sheets plus a helical spring connected to the two ends of the metal sheet) will increase the production cost, and the elastic structure 17 is attached to The assembly process of the drive belt 13 is quite complicated, and the additional thickness and width after assembly are not conducive to the arrangement of the scanner 1 space

Embodiment Construction

[0038] The driving belt described in the present invention is an annular structure composed of more than two sections of belt materials with different elastic coefficients, which are respectively the belt main body 21 and the elastic body 22, such as Figure 3A As shown, the modulus of elasticity of the elastic body 22 is lower than that of the belt main body 21 . According to the definition of elastic coefficient: elastic coefficient=(stress / strain), under the same tension, the elastic body 22 can provide a larger unit deformation than the belt main body 21 . Therefore, in addition to providing the same working function as the known driving belt, the driving belt also provides a length variation of the driving belt within an external force range. With the change of the length of the drive belt, the drive belt can be easily fitted to the roller set on the scanner housing, and the tension required for the drive belt to work can be obtained without additional sets.

Abstract

The present invention is drive belt and the platform scanning instrument therewith, and relates to optomechanical assembly driving in platform scanning instrument. The drive belt is one combination of over two sections of elastic material in different elastic coefficients, and has simple installation, less additional parts needed, high production efficiency and low production cost.

Description

technical field [0001] The invention relates to a driving belt and a flatbed scanner including the driving belt, in particular to a driving belt applied to a flatbed scanner. Background technique [0002] Please refer to figure 1 , the movement of the optical machine module 11 on the platform scanner 1 is driven by a driving mechanism 12 to drive a driving roller 15 to drive a driving belt 13, and the power generated by the driving mechanism 12 is converted into the power of the optical machine module 11. displacement. [0003] Please refer to Figure 2A , during the assembly process of the mechanism, when the drive belt 13 is to be installed and fixed on the active roller 15 and the other driven roller 16 on a scanner housing 14, the length of the drive belt needs to be stretchable to be slightly larger than that shown in the figure. a+b+c+d, so that the assembly can be completed smoothly. [0004] When the driving roller 15 is powered by the driving mechanism 12 to rot...
