Abstract

PURPOSE:To reduce a lateral given installation space and to eliminate problem on the safe specification of a sorter rest supporting a sorter, by a method wherein the sorter is situated to the upper part of a laser printer and adjacently to a reversing device. CONSTITUTION:Arrangement of a laser printer 1, a cabinet 2, a mass feed unit 3, and a reversing device 4 is the same as that of a conventional type. But, instead of a sorter 5 being supported to a sorter rest by means of the side of a laser printer system, the sorter 5 is situated to the upper part of the laser printer 1 and adjacently to the reversing device 4. Differentially from a duplicator, the laser printer 1 is provided on its upper surface with no moving part and therefore, the above arrangement is practicable. This constitution sharply reduces lateral given installation space, eliminates a sorter rest 6, and removes a problem on safety specification.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a laser printer for printing video data.
A cabinet containing a printer controller that controls the system of the laser printer and various options through an interface with a host computer, a large-volume paper feed unit that is removable from the cabinet and supplies a large amount of printing paper to the printer, and a laser. The present invention relates to a laser printer system including a reversing machine for receiving printed paper from a printer, reversing it as necessary, and discharging it, and a sorter for receiving and sorting the paper from the reversing machine.

Due to its low price, laser printer systems have become popular for a variety of uses, from output means for large computers to output devices for word processors and the like in general offices. This has led to the problem of installation space.

In conventional laser printer systems, the sorter is usually installed on the paper output surface of the printer, ie, on the side of the entire system, as in a copying machine. The arrangement of such a conventional laser printer system will be explained with reference to the drawings.

In FIG. 2, the laser printer system includes a laser printer 1, a cabinet 2 in which the laser printer is placed, a mass paper feed unit 3 for supplying a large amount of printing paper to the laser printer 1, and a large amount of printing paper from the laser printer 1. The apparatus is provided with a reversing machine 4 DEG for receiving sheets of paper, reversing the sheets as necessary, and discharging the sheets, and a sorter 5 for receiving and sorting the sheets discharged from the reversing machine 4. 6 is a sorter stand that supports the sorter 5.

The laser printer 1 includes two paper feed cassettes IA and IB that accommodate paper of different sizes. The internal structure of the laser printer 1 is conventionally known, and therefore
I won't go into details. The discharge lower of the printed paper is connected to the paper feeder 8 of the reversing machine 4.

The cabinet 2 has the laser printer 1 placed therein and also houses a printer controller therein, and this printer controller performs system control of the laser printer, various options, etc. through an interface with a host computer.

The large-volume paper feed unit 3 is removably attached to the cabinet 2 and stores a large amount of paper, and each paper can be fed into the printing process of the laser printer 1 by a paper feed mechanism 9.

The reversing machine 4 uses a roller switching mechanism 10 to reverse or not reverse the printed paper introduced from the paper feeder 8 and sends it to the sorter 5, or sends it upward through the roller switching mechanism to a paper output tray using a discharge roller 11. 12 Discharge onto the top. 13 is a bin equipped on the sorter 5.

As shown in FIG. 2, the sorter 5 is disposed on the side of the laser printer system, as in a copying machine, and is supported by a sorter table 6.

A laser printer system with a sorter is a large model such as a high-speed machine, and if the sorter is installed on the side as described above, the installation space will become large and problems will arise regarding the safety standards of the sorter stand that supports the sorter. There is.

SUMMARY OF THE INVENTION The present invention aims to eliminate the above-mentioned disadvantages in laser printer systems of the type described in the technical field.

The above objects are achieved in accordance with the present invention by locating the sorter on top of the laser printer adjacent to the inverter.

tip (sha) The present invention will be described in detail below with reference to the accompanying drawings.

The laser printer system according to the present invention shown in FIG.
Regarding the arrangement of the laser printer 1, the cabinet 2, the bulk paper feed unit 3, and the reversing machine 4.

This is the same as shown in FIG. What is different from Figure 2 is that
The point is that the sorter 5 is arranged above the laser printer 1 and adjacent to the reversing machine 4. Unlike a copying machine, a laser printer has no movable parts on the top surface of the printer, so the above arrangement is possible. By comparing FIG. 1 and FIG. 2, it can be clearly seen that the required lateral installation space for the laser printer system of the present invention is significantly reduced and the sorter table 6 is no longer required.

Japan-U.S. The present invention has made it possible to significantly reduce the installation space of a laser printer and to reduce problems related to safety standards.
