Abstract

PURPOSE:To eliminate the necessity of changing over a size indicating means by automatically indicating the size of a sheet material which is housed in the loading in the title for a copier or the like, while one of the device proper and either one of a laterally regulating plate or a rear edge direction regulating plate, with a paper sheet size indicating means, and also providing the other one with an indicating panel. CONSTITUTION:An indicating needle 111 is attached to a rear edge position regulating plate 4. Consequently, when a cassette proper 1 is loaded with paper sheets 3 and the rear edge positions of the paper sheets 3 are regulated by the rear edge position regulating plate 4, the indicating needle 111 moves to a position corresponding to the size of the paper sheets 3. On the other hand, a paper sheet size indicating panel 112 is attached to the cassette proper 1 in its position corresponding to the indicating needle 111 so as to indicate the size of the paper sheets 3 ranging from B5 to A3, in such a way as the position of the tip portion 111a of the indicating needle 111 shows the size of the paper sheets 3.

Description

Detailed Description of the Invention [Industrial Application Field] The present invention is a method for sequentially feeding sheet materials such as recording sheets that are installed in equipment such as a printer, a copying machine, or a printing machine and stored in a stacked state. The present invention relates to a paper feeding sheet material stacking device that can feed paper.

[Prior Art] FIG. 4 shows a sectional view of a paper feed cassette, which is an example of a conventional paper feed sheet material stacking device.

This paper feed cassette is a so-called universal cassette that can load and store sheet materials of various sizes. 1 is a cassette body, and when it is installed in a device body 9 such as a printer or a copying machine, an intermediate plate 2 for loading sheet materials presses a sheet material 3 against a paper feed roller 6 by a spring 7 to determine the paper feeding position. It is kept constant. 1
0 is a cover of the cassette, and 4 is a rear end position regulating plate for regulating the rear end position of the sheet material 3, which slides on the guide 5 in the direction of the arrow according to the size of the sheet material to be loaded.

In addition, the width direction regulation plate 8 that regulates the width direction position of the sheet material 3 is also provided with another width direction regulation plate (not shown) located opposite to the width direction regulation plate 8.
In conjunction with this, it similarly slides in a direction perpendicular to the plane of this drawing in accordance with the sheet material size.

[Problems to be Solved by the Invention] However, the conventional example shown in FIG. 4 has the following problems.

When sheet materials of various sizes are loaded into a cassette and then loaded into a printer, copying machine, or the like for use, it may become unclear what size sheet materials are inside the cassette. Insert the cassette again into the device body 9.
Even if the sheet material in the cassette is visible after removal from the cassette, it is often difficult for the user to remember or for another user to determine the size of the sheet material by looking at it.

On the other hand, some models have labels attached to the outside of the cassette to indicate the size of the sheet material, but the user must replace the labels each time a different size sheet material is set. There were complications such as having to

The present invention has been made in view of the above problems, and its purpose is to enable the size of the stored sheet materials to be easily determined from the outside, and to enable the user to switch the size display means. An object of the present invention is to provide a feeding sheet material stacking device that eliminates complexity.

[Means and effects for solving the problem] The present invention displays the size of the sheet materials loaded inside in conjunction with either a width regulating plate or a rear end position regulating plate that moves according to the size of the sheet material. By adding the mechanism, the user can easily know the size of the currently stored sheet material.

[Example] A first embodiment according to the present invention is shown in FIG.

FIG. 1 is a cross-sectional view of the paper feed cassette, where 1 is the cassette body which is the main body of the device, 2 is the middle plate for loading sheet materials,
A spring 7 presses the sheet material 3 against the paper feeding roller 6 to keep the paper feeding position constant. Reference numeral 9 denotes the main body of the equipment such as a copying machine or printer, IO the cover of the cassette, and 4 a rear end position regulating plate for regulating the rear end position of the sorting material. Slide in the direction of the arrow. A display needle 111 is attached to the rear end plate regulating plate 4 and moves in the direction of the arrow in conjunction with this. The display board 112 has one display needle for each size of sheet material.
The size of the sheet material is written at the position indicated by the tip 111a of No. 11. That is, when the rear end position regulating plate 4 is aligned with the rear end of the stored sheet material 3, the tip portion 111a of the indicator needle 111 automatically indicates the current sheet material size on the display board 112. In addition, the display hand Il
The entire cassette body 1 or only a portion of the cassette body 1 is formed with holes or a transparent material so that the cassette body 1 and the display plate 112 can be visually recognized from the outside.

[Other Embodiments] Next, other embodiments of the present invention will be described. The other embodiments differ from the first embodiment only in the display mechanism for displaying the size of the sheet material, so only the different parts will be explained.

A second embodiment according to the invention is shown in FIG.

In FIG. 2, a display plate 212 is attached to the rear end position regulating plate 4 and is movable in the direction of the arrow in conjunction with this. Further, the cassette body 1 is provided with a display window 211, and on a display board 212, the current sheet material size is written for each sheet material size at a position that matches the display window 211. With this configuration, the user can always visually recognize only one type of sheet material size, resulting in a display that is easier to distinguish.

FIG. 3 shows a third embodiment of the present invention.

In FIG. 3, a rack 311 is attached to the rear end position regulating plate 4. As shown in FIG. On the other hand, a circular display plate 312 is provided on the cassette main body l. The rack 311 can rotate around the shaft 313, and its outer periphery is a gear.
It meshes with the. When the rear end position regulating plate 4 is aligned with the rear end of the sheet material, the display plate 312 rotates in conjunction with this. At this time, the size of each sheet material is written on the cover plate 312 at a position that matches the display window 314 provided in the cassette body 1.

In each of the above embodiments, the size of the sheet material is displayed in conjunction with the rear end position regulating plate, but the same effect can be obtained by using a configuration in conjunction with the widthwise regulating plate. As described above, the present invention is not limited to just one type or configuration, and various modifications and configurations are possible.

In addition, in the above embodiment, the present invention was applied to a cassette type paper feeding sheet material loading device installed in equipment such as a printer, but it is installed integrally with equipment such as a printer, and driven by a driving means such as a motor. The present invention can also be applied to other types of paper feed sheet material stacking devices such as a deck type in which the intermediate plate is displaced depending on the remaining amount of sheet material.

[Effects of the Invention] As explained above, by adding a mechanism that displays the size of the sheet material stored inside in conjunction with the width regulating plate or the rear end regulating plate that moves according to the size of the sheet material. The following effects can be obtained.

(1) You can always check the size of stored sheet materials.

(2) When replacing the sheet material with a sheet material of a different size, the size display can be automatically changed.
