In the present invention, when sorting in a copy paper sorting apparatus (hereinafter, simply referred to as a `` sorter '') having a plurality of stacked bin trays, the bin tray for storing paper and the upper bin tray adjacent thereto are provided. The present invention relates to a bin tray driving apparatus of a sorter for lifting a spaced portion by a predetermined interval, and more particularly, to a bin tray driving apparatus of a sorter having a slide bin tray separator, which enables smooth paper storage with little power.

In general, the sorter includes a plurality of stacked bin trays. In order to store and load copy paper in each of the bin trays, the sorter is adjacent to the bin tray at regular intervals when the copied paper is discharged from the copier body. Open the upper bin tray so that the discharged paper can be loaded smoothly. After the paper is discharged, the copied paper is sequentially stored in the plurality of bin trays by returning the upper bin tray adjacent to the bin tray to its original state.

Looking at the bin tray feeder of the conventional sorter, U.S. Patent Nos. 3,788,640 and 4,738,443 use the large cam gear to handle the individual transfer of bin trays to provide paper storage space and the entire transfer of laminated structure. Patent Nos. 4,328,963, 4,332,377 and 5,035,412 use one transfer wheel or cam gear and spring for them, and in the case of Nos. 4,337,936, 4,878,6655, 5,082,257 and 5,088,709 It is proposed to use a gear, two or three transfer wheels, but limit the distance between the top and bottom bin trays using guide means or levers.

In addition, in the bin tray conveying apparatus disclosed in US Patent No. 5,178,382 by the applicant, the entire tray is used to transfer the bin trays, thereby reducing the instantaneous overload generated during bin tray transfer, but individually transferring the bin trays. When driving the means, there was a problem in that all bin trays located above the bin tray should be lifted together.

On the other hand, US Patent No. 4,843, 434 employs a BIN OPENING FINGER to expand the space between adjacent bin trays to accommodate the paper discharged from the copier as one structure for improving the problem. In this case, the upper and lower guide pull plate driving morty and the motor for driving the empty opening finger are provided, respectively, and the upper and lower guide plates are gradually stopped. It is to control through the separate motor and the ring belt and the sensor, the paper discharge position of the upper and lower feed rollers were to be changed at the same time during the shanghai of the upper and lower guide plates. However, in this case, since the guide plate driving mode and the empty opening finger driving motor must be provided and controlled as described above, the configuration is complicated, and the larger the number of bin trays provided, the more paper is discharged. The length of the guide plate for supplying to each empty tray had to be formed longer, thereby requiring a large space, there is a problem that the volume is large.

As described above, in all conventional structures, since a predetermined paper storage space is formed by lifting all the bin trays located above the bin tray in which the paper is stored, not only power loss but also a lot of noise are generated. Since some or all of the loads of the entire bin tray transfer, in which the load is changed depending on the position of the bin tray, are added to the individual transfer means for providing the paper storage space, the individual transfer means always has a maximum size load. It has technical challenges that it must be acceptable and configured to perform certain actions regardless of load changes.

Therefore, the present invention has been devised to solve the above problems, but adopts a rack (RACK) structure to move the plurality of bin trays stacked in a row, a plurality of empty pin guide racks on the rack It is to provide a bin tray driving apparatus of the sorter to perform the bin tray separation operation to form a shanghaidong and paper storage space of the rack as a single motor so that each of the bin trays are independently covered.
