Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a paper feed cassette device, and more particularly to a paper feed cassette device that can be applied to an apparatus equipped with a paper feed device such as a copying machine or a printing machine.

(Prior art) Conventionally, from the idea of effectively utilizing office space, in order to minimize the installation area, paper feed cassettes for storing paper were completely housed within the main body of devices such as copying machines and printing machines. In the conventional apparatus configured as described above, there are roughly two types of means for displaying the size of paper stored in the paper feed cassette. One method is to use electrical means to detect the size of the paper feed cassette or paper and display it on the display board of the operation section of the main body of the device. 8, a through hole 12 is formed in the front part of the frame 11 of the paper feed cassette 10, and a receiving hole 13 is formed inside the frame 11 corresponding to the through hole 12. A dice-shaped display member 14 with a paper size written on the circumference is housed in the receiving hole 13, and the display surface corresponding to the paper size is
It is positioned toward the through hole 12 side so that the paper size can be confirmed from outside the paper feed cassette 10.

However, both methods are costly, and in order for the user to know the paper size stored in the device, the user must go near the device and check the small letters displayed on the display board of the operation section. Nakatsuta. Further, in the latter case, if the user forgets to replace the display member 14, the paper size and the displayed size value will not match, which may lead to an operational error by the next user.

(Purpose) The purpose of the present invention is to provide a paper feed cassette device that solves the problems of the prior art described above and allows the user to easily and reliably check the paper size in the paper feed cassette at all times. shall be.

(Configuration) In order to achieve the above purpose, the present invention stores paper inside the device, feeds paper while stored in the device main body, and changes the internal paper size even when removed from the device main body. Further, in a paper feed cassette device equipped with a paper size display device that can display the paper size even when the paper size is stored in the device main body, the paper feed cassette that stores the paper, and the paper feed cassette of the device main body that stores the paper feed cassette are provided. a larger cassette tray, and the paper size display device includes:
It consists of a connecting lever whose one end is rotatably supported by the paper feed cassette, a horizontal part rotatably provided at one end of the connecting lever, and a display plate perpendicular to the horizontal part, The paper feed cassette is provided with a receiving part for receiving one side of the connection lever, and the cassette tray is provided with a receiving part for receiving one side of the horizontal part. displaying the display board on the outside of the paper feed cassette by folding the paper size display device;
When displaying the size on the cassette tray, the paper size display device is extended and displayed outside the cassette tray. The present invention will be specifically described below based on one embodiment of the present invention.

1 to 6 show an embodiment in which the present invention is applied to a copying machine.

That is, as shown in the perspective view of FIG. 1, the copying machine main body 1 consists of a document setting section 1a, a paper ejecting section 1b, an operating section 1c, etc. as is well known, and a paper feeding section is located on the same side as the operating section 1c. A cassette tray 1d capable of storing cassettes 2 is provided in and out of the main body 1 at will.

As shown in the perspective view of FIG. 2, the cassette tray 1d stores therein a paper feed cassette 2, which will be described later, with the cassette cover 2a removed.
Paper 3 is exposed in the cassette tray 1d. After the cassette tray 1d is housed in the main body 1, the paper feeding operation is performed in the same manner as in the known method.

As shown in the perspective view of the paper feed cassette 2 shown in FIG. 3, the paper feed cassette 2 consists of a tray section 2b on which paper 3 is placed, and the cassette cover 2a fitted onto the tray section 2b. paper 3 on the front side.
A display board 4 which is a display device for displaying the size of is arranged. Therefore, this display board 4
is relatively large and large enough for the user to easily and reliably check the paper size.

In addition, as shown in FIG.
By placing the display board 4 on top so that it faces forward, it becomes easy to select paper feed cassettes 2 with different paper sizes.

Next, the support mechanism of the display board 4, which is a display device, and its operation will be explained with reference to FIGS. 5 and 6.

Fig. 5 shows the paper feed cassette 2 stored in the cassette tray 1d of the main body 1 with the cassette cover 2a removed. Movement of cassette 2 to the left is prevented. The front side 2c of the paper feed cassette 2 has a cassette tray 1d.
In this state, the display board 4 is placed at a distance from the front side surface 1e, which serves as a receiving portion for receiving one side of the horizontal portion 4b.
The display board 4 is placed on the stepped portion 1f of the paper feed cassette 2 so that it can be seen from the front surface of the paper feed cassette 2.

The display board 4 has a substantially "shaped" shape when viewed from the side, with a vertical portion 4a engaged with the front side surface 1e, and a horizontal portion 4b.
is rotatably supported by one end of the connecting lever 6, and the other end of the connecting lever 6 is rotatably pivoted to the upper end of the front side surface 2c of the paper feed cassette 2.

Therefore, when the paper feed cassette 2 is stored in the cassette tray 1d as described above, the user can check the paper size from outside the main body 1 by placing the display plate 4 on the stepped portion 1f of the cassette tray 1d. .

Further, when the paper feed cassette 2 is taken out from the cassette tray 1d, the cassette cover 2a is fitted, and the paper feed cassette 2 is to be moved to an appropriate location, the connecting lever 6 is rotated clockwise as shown in FIG. When the display plate 4 is folded onto the connecting lever 6, the display plate 4 is folded onto the receiving part 2d formed at the upper part of the front side surface 2c of the paper feed cassette 2 via the connecting lever 6.
The horizontal part 4b of the display board 4 will be placed on it.
The vertical portion 4a is located at the front of the paper feed cassette 2. Therefore, even when the paper feed cassette 2 is taken out from the cassette tray 1d as described above, the display board 4
By placing the paper on the tray 2d of the paper feed cassette 2, the user can check the paper size from outside the paper feed cassette 2.

In FIGS. 5 and 6, 2e is the paper feed cassette 2 that serves as a receiver when the cassette cover 2a is fitted.
7 is an escape hole formed in the cassette cover 2a to position the display plate 4 in front of the paper feed cassette 2.

In this way, in this embodiment, the paper feed cassette 2 can be detected when it is removed from the main body 1 and when it is stored in the main body 1 by using a simple mechanism and the same display board 4 without using any special electrical means. The paper size can be easily displayed outward when the paper size is pressed, and the operation of the display board 4 is simple and there is no possibility of operator error.
The next user will no longer have to copy the paper incorrectly by using the wrong paper size.

(Effects) As explained below, the present invention can provide a paper cassette with a simple configuration that always displays the paper size inside the paper cassette externally and allows the user to easily and reliably check the paper size. .
