Multi-function peripheral

Abstract

A multi-function peripheral (MFP) suited for printing/scanning a paper or a business card is provided. The MFP includes a body and a printing/scanning unit, a feeding roller, and a plurality of idle rollers disposed in the body. The body has a feeding path that the printing/scanning unit, the feeding roller, and the idle rollers are located thereon. The printing/scanning unit used for printing/scanning the paper or the business card on the feeding path. The idle rollers lean against the feeding roller respectively. A path length between two leaning points of any two adjacent idle rollers contacting the feeding roller is shorter than a size of the business card.

What is claimed is: 
     
         1 . A multi-function peripheral (MFP), adapted to print and scan a piece of paper or a business card, the MFP comprising:
 a body, having a feeding path;   a scanning/printing unit, disposed in the body and located on the feeding path, wherein the scanning/printing unit performs scanning/printing towards the paper or the business card passing through the feeding path;   a feeding roller, disposed in the body and located on the feeding path;   a plurality of idle rollers, disposed in the body and located on the feeding path, wherein the idle rollers respectively lean against the feeding roller, wherein on the feeding path, a path length of two leaning points of any two adjacent idle rollers contacting the feeding roller is shorter than a size of the business card.   
     
     
         2 . The multi-function peripheral as claimed in  claim 1 , wherein a dimension of the business card includes 5 cm×9.4 cm or 10 cm×9.4 cm. 
     
     
         3 . The multi-function peripheral as claimed in  claim 1 , wherein a diameter of the feeding roller is greater than or equal to  1 . 75  times a diameter of each of the idle rollers. 
     
     
         4 . The multi-function peripheral as claimed in  claim 1 , wherein the body further includes a paper entrance and a paper exit, the piece of paper or the business card respectively enters the feeding path through the paper entrance, and exits the body through the paper exit. 
     
     
         5 . The multi-function peripheral as claimed in  claim 4 , further comprising:
 a paper pick-up roller, located on the feeding path and adjacent to the paper entrance;   a paper dividing roller, located on the feeding path and between the paper pick-up roller and the feeding roller; and   a paper exit roller, located on the feeding path and adjacent to the paper exit.   
     
     
         6 . The multi-function peripheral as claimed in  claim 1 , wherein the body comprises:
 a base, having the feeding path;   a top cover, assembled to the base lifted or shut, so as to cover the feeding path; and   a flexible element, connecting the top cover and one of the idle rollers, wherein when the top cover is removed from the base, the idle roller is removed from the feeding path with the top cover, wherein when the top cover is assembled to the base, the top cover and the flexible element drive the idle roller to lean against the feeding roller.   
     
     
         7 . The multi-function peripheral of  claim 1 , wherein a hardness of the business card is greater than a hardness of the piece of paper. 
     
     
         8 . The multi-function peripheral as claimed in  claim 1 , wherein the feeding path includes at least one curve. 
     
     
         9 . The multi-function peripheral as claimed in  claim 8 , wherein the feeding roller is located at an area of the curve. 
     
     
         10 . The multi-function peripheral as claimed in  claim 9 , wherein a curvature radius of the feeding roller is less than or equal to a curvature radius of the curve.
