Problems solved by technology

[0004] However, in the above-mentioned patents, the rotating shaft is directly inserted into the open shaft hole and the buckling action of the buckle structure will generate an additional radial force on the rotating shaft, resulting in increased friction between the shaft hole and the rotating shaft
If the open shaft hole is only set on one side of the back plate to install one end of the shaft, it will cause the shaft to be deflected, which will cause the paper feeding process to be unsmooth

Embodiment Construction

[0013] In order to improve the shortcomings of the above-mentioned prior art, the present invention designs the mechanism for fixing the replaceable friction wheel set on the shaft sleeve, which can avoid the use of additional parts to fix the friction wheel set, and avoid the friction on the rotating shaft of the friction wheel set. cause additional radial force.

[0014] FIG. 1 is a schematic diagram of an automatic paper feeder with replaceable friction wheel sets according to a first embodiment of the present invention. Figure 2 shows a partially enlarged view of Figure 1 . As shown in FIGS. 1 and 2 , the automatic paper feeder with replaceable friction wheel set of the present invention includes a housing 10 , a supporting component 12 , a first buckle structure 16 and a friction wheel set 20 . The casing 10 has a backboard 10A that can be opened and a base 10B that is pivotally connected to the backboard 10A. When feeding paper, the backboard 10A covers the base 10B, an...

Abstract

An automatic paper feeder with replaceable friction wheel consists of a rear panel enabling to be opened and a base case pin joint with it, support component with a shaft hole on shell, a first clutch buckle structure which rotary mounted on the rotary shaft, a friction wheel set including a rotary shaft, a friction wheel and a first shaft sleeve, a second clutch buckle structure setting on the first shaft sleeve and fastening with the first one . It features that the friction wheel set can be replaced by separating the second clutch buckle from the first one.

Description

technical field [0001] The invention relates to an automatic paper feeder with replaceable friction wheel sets, in particular to an automatic paper feeder that utilizes the locking method of the shaft sleeve to fix the rotating shaft of the friction wheel sets so that users can replace the friction wheel sets by themselves. device. Background technique [0002] The friction wheel set of the automatic document feeder on the traditional scanner is a consumable part for feeding paper, so it must be replaced after a period of use to maintain the proper paper feeding quality. However, the friction wheel set is usually fixed on the back plate of the automatic document feeder through a mounting component such as a C-shaped buckle. The disassembly of the C-shaped buckle is not easy for ordinary users to complete, so the user cannot replace the friction wheel set by himself. [0003] The Republic of China Patent Publication No. 547458, jointly assigned to the assignee of this case,...
