〔Example〕

Embodiments of the present invention will be briefly described below.

In order to achieve the object of the present invention, it is necessary to carry out printing by transporting a plurality of sheets of printing paper from the automatic paper feeder to the printer main body independently or simultaneously in one suction operation.

For example, here we describe the case where two sheets of paper are sucked in at the same time.There is a pickup roller that is movable and located on the left and right to separate and transport the printing paper, and a roller that is in contact with the pickup roller and is necessary for separating the printing paper. In addition to the existing left and right paper storage hoppers that have separation pads that generate frictional force to hold printing paper, they are movable and can hold printing paper on both sides, and as above, the pickup roller and separation pad are also installed on the side. By adding a paper intermediate guide such as a paper intermediate guide and dividing the printing paper storage space into two,
It is possible to store various types of printing paper.

When each paper is to be sucked independently, a clutch is provided in the pickup roller section, and the paper to be sucked is selected while being switched by the clutch.

Regarding the combination of printing papers, the sum of the paper widths of the two types of printing papers to be stored is less than or equal to the maximum paper width that the automatic paper feeder can support. In addition, in order to accommodate printing paper of the maximum paper width that the automatic paper feeder can support, an additional paper intermediate guide is installed.
It should be easy to install and remove depending on the operator's handling, or it should be able to move freely up and down, or slide freely in the left and right directions.

Simultaneous printing of the same document, simultaneous printing of different pages of the same document,
For simultaneous printing of different documents, it is equipped with a memory that can store print data for multiple pages, and the received data is sequentially stored and edited in the memory, and printing is controlled based on the print mode. It is.
