ろことが可能な枚葉紙収納装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a multi-stage sheet storage device that is applied to image recording devices such as copying machines and facsimile machines, and particularly relates to a multi-stage sheet storage device for storing sheets cut into various sizes. A sheet paper storage container capable of stacking a large number of individually stored sheet storage containers vertically in multiple stages, and exposing the upper surface of the paper sheet delivery side end of any sheet storage container as necessary. This invention relates to a storage device.

用される様になった。Conventional Image Recording Devices, such as electrophotographic copying machines, are becoming increasingly popular with models equipped with 7 multi-step reduction and enlargement functions, and such models require a wide variety of paper sizes and a large number of paper storage containers. A structure has come to be adopted in which copy sheets are arranged in multiple stages, and copy sheets of a desired size are automatically selected and transported by a paper transport means.

必要があり、複写作業能率が損なわれることになる。However, when paper storage containers are arranged in multiple stages, it is necessary to secure space between the upper and lower paper storage containers for the paper ejection means provided for each paper storage container, and the paper storage containers The paper storage depth becomes shallow, and the binding mechanism becomes cumbersome due to the need to move a large number of paper delivery means. If you want the paper storage depth to be large enough, prepare a number of cassette-type paper storage containers, make it possible to install a few of them into the copying machine, and select the paper storage container you need as appropriate. It is necessary to replace and install it, which impairs the efficiency of copying work.

ゼしぬる。Means and Effects for Solving the Problems In the present invention, in a sheet storage device for an image recording apparatus in which sheet storage containers are arranged in multiple stages, each sheet storage container is It is configured so that it can be moved diagonally upward on the opposite side from the paper delivery side, and in order to transport paper from storage containers other than the sheet storage container located at the top level, each sheet storage container must be moved diagonally upward. The binding means is operated so as to be able to separate and move the upper group located one stone above the target storage container and the lower group containing the target storage container, and by the subsequent operation of the drive means, the upper group and lower group are separated. The group is relatively displaced diagonally upward or diagonally downward, and a sheet conveying means is provided at a partially exposed target storage container position, and the sheet is conveyed out.

することが可能となり、装置構造も簡略化される。More than the effects of the invention, as is clear from the description of the embodiments, in the present invention, in an image recording apparatus in which sheet storage containers are arranged in multiple stages, each sheet storage container is Since the sheet storage container is configured so that it can be moved obliquely upward on the opposite side from the paper delivery side, the end of the delivery side of any sheet storage container can be exposed and set by the selective operation of the binding means and the operation of the drive means. It is possible to bring the sheet transport means to the exposed position of the sheet storage container and transport the sheets. Therefore, there is no need to provide a sheet ejecting means for each storage container, which greatly saves space compared to conventional multi-stage sheet storage containers, and allows for high-density storage of many types of sheets. This also simplifies the device structure.
