Scanning and printing all-in-one machine sharing power source

Abstract

The invention discloses a scanning and printing all-in-one machine sharing a power source, a first channel and a sharing channel form a scanning channel, a second channel and the sharing channel form a printing channel, a printing device is installed at the sharing channel, and a scanning device is installed at the first channel or the sharing channel; and a first paper guide roller is arranged in the first channel, a second paper guide roller is arranged in the second channel, a third paper guide roller is arranged in the common channel, the main driving mechanism drives the third paper guide roller to rotate, and the reversing mechanism selectively transmits power of the main driving mechanism to the first paper guide roller or the second paper guide roller through the third paper guide roller. The all-in-one machine not only can independently realize a scanning copying function and a printing function, but also can perform printing on scanned paper, and also can perform printing after scanning, so that the all-in-one machine is more convenient to use. Meanwhile, the first paper guide roller and the second paper guide roller can share one power source, a power source does not need to be arranged independently, cost is greatly reduced, and miniaturization can be achieved.

Description

technical field [0001] The invention relates to a scanning and printing all-in-one machine with a shared power source. Background technique [0002] Scanning and printing all-in-one equipment usually includes two main parts: one is a scanning device and the other is a printing device. According to different structures, the integrated scanning and printing equipment is generally divided into two types: the first type is the integrated scanning and printing equipment in which the scanning channel and the printing channel are not directly connected, and a typical example is a copier; the second type is the scanning channel and the printing channel. A scanning and printing integrated device connected by channels, a typical example of which is a waste ticket processing device. [0003] A copier may be taken as an example to illustrate the working process of the first type of integrated scanning and printing device. When the copier is working, the original file is first input in...

AI Technical Summary

Problems solved by technology

[0005] It can be seen from the working process of the above waste ticket processing equipment that the second type of scanning and printing integrated equipment only has the function of scanning and printing marks on the scanned media, but does not have the function of printing, and an additional printing device is required. Therefore, It is very inconvenient to use and increases the cost of use

[0006] Moreover, the existing printers often require different power sources to drive independent transmission systems when realizing different functions, resulting in complex structural design, and at the same time, the increase in power sources increases the cost
