Problems solved by technology

[0015] However, in the existing image reading device shown in FIG. 5 , the flywheel 17 installed on the motor 15 is expensive, and there is a disadvantage of cost increase. If the weight 18 is installed on the transmission shaft 2, additional installation is required. area, there is a disadvantage that the device becomes larger

Embodiment 1

[0038] figure 2 It is a perspective view of the first embodiment of the anti-vibration device of the present invention. In addition, for this figure with figure 1 The same structural parts are given the same symbols, and therefore descriptions thereof are omitted. With reference to this figure, the weight 19-1 is composed of the following components: a first component 41, whose cross section is U-shaped; The first member 41 is wide; the third member 43 is provided at the other end of the first member 41 , and the first member 41 to the third member 43 are integrally formed.

[0039] However, it is also possible to use the first member 41 and the second member 42 as independent members, and adopt a mutually joined structure.

[0040] In addition, a hole (not shown) through which the screw 25 passes is formed in the third member 43 , and the weight 19 - 1 is attached to the CCD substrate 23 by the screw 25 through the hole. In addition, the installation position of the wei...

Embodiment 2

[0045] Figure 4 It is a perspective view of the second embodiment of the anti-vibration device of the present invention. In addition, for this figure with figure 2 The same structural parts are given the same symbols, and therefore descriptions thereof are omitted. Referring to the figure, the weight 19-2 is different in shape from the weight 19-1 in the first embodiment in that the fourth member 44 corresponding to the second member 42 in the first embodiment is formed as a flat plate. Other shapes are the same as the first embodiment.

[0046] According to the second embodiment of the present invention, since the fourth member 44 does not need to be bent, the number of steps can be reduced.

[0047] (industrial availability)

[0048] In this embodiment, as the shape of the weight 19, figure 2 and Figure 4 An example is shown in , but it is not limited to these. As long as the following conditions are satisfied, the present invention can also be applied to the canti...

Abstract

The invention discloses an image reading device with weight to assemble driving shaft, which is characterized by the following: assembling suspending arm beam-shaped weight (19) on the CCD base (23) of optical component (3) in the image reading device through screw (25). The weight (19) contains first component (41), which cross section displays U shape; second component (42), which is set on one end of first component (41) with U shape breadth broader than first component (41); third component (43), which integrates first, second and third component (41)-(43) on another end of first component (41).

Description

technical field [0001] The present invention relates to an image reading device and an anti-vibration device used therefor, and more particularly, to an image reading device such as a copier, a facsimile machine, an allied machine, and a scanner, and an anti-vibration device therefor. Background technique [0002] 5 is a plan view showing an example of the structure of a conventional image reading device, and FIG. 6 is a sectional view taken along line A-A' in FIG. 5 . [0003] With reference to Fig. 5 and Fig. 6, an example of existing image reading device, its structure comprises: drum 1; Drive shaft 2; Optical unit 3; Lighting unit 4; Mirror unit 5; Metal wire 6; Guide rail 7; Base plate 8; Glass 9; Lamp 11; Belt wheel 12 (12-1, 12-2); Mirror 13 (13-1~13-3); Timing belt 14; Motor 15; Belt wheel 16; Flywheel 17; Heavy A hammer 18 ; an imaging element substrate (as an example, a CCD (Charge Coupled Device) substrate, hereinafter referred to as a CCD substrate) 23 on which ...
