Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a tray device, and more particularly, to positioning of a tray in a tray attached to a main body of a copying machine, for example. For example, there are trays for feeding paper and trays for discharging paper, but the same applies in both cases. Further, the paper feed tray includes a tray that can load a plurality of sheet materials (original documents, copy paper, etc.), and a tray into which a single sheet can be inserted manually (manual feed tray).

[Conventional technology]

Conventionally, the paper feed/discharge tray of a copying machine has been attached by inserting a dowel provided on the paper feed/discharge tray into a hole formed in the copying machine.

However, if the dowels were not completely inserted, the paper feed/discharge tray would be dislocated during use or would be installed in a crooked state, making it impossible to carry the paper normally.

[Purpose of invention]

The present invention has been made in view of the drawbacks of the above-mentioned conventional examples, and an object of the present invention is to provide a tray device that is easy to install.

〔Example〕

FIG. 1 shows one embodiment of the present invention, where 1 is a copying machine body, 1a and 1b are holes attached to the copying machine body, and 2 is a paper feed tray. 2a and 2b are dowels that fit into the holes 1a and 1b, and the width of the hole 1b and dowel 2b in the X direction is a size that allows the dowels to be fitted in the X direction to position the paper feed tray in the X direction when the dowels are inserted into the holes. It is becoming. The paper feed tray 2 is housed and assembled as shown in the figure using support pins and springs (not shown).

In Figure 2, rotate the support pin (not shown) 90° upward from the state in Figure 1, and
The dowels 2a and 2b are inserted into the dowels 2a and 2b and set so that paper can be fed. 3a and 3b are guides that are slid along the groove 2a to match the width of the paper, and 4 is copy paper.

FIG. 3 is a diagram showing the dowel 2a section, and the third
Figure a shows the state shown in Figure 1 above. The paper feed tray 2 has a pin 6 attached to the main body with a dowel 2a.
It is supported by being inserted into the groove 2c of the section. Figure 3b is 90° from the state of Figure 3a around the support pin 6.
It shows how it is rotated. FIG. 3c shows the state shown in FIG. 2, in which the dowel 2a is inserted into the hole 1a. The paper feed tray 2 is supported by support pins 6 and the bottom surface of the guide 5 of the main body 1.

FIG. 4 is a diagram showing the dowel 2b portion, and the fourth
Figure a shows the state shown in Figure 1 above. The spring 7 is hung on the dowel 2b portion and the main body fixing portion 8.
A spring 7 prevents the paper feed tray 2 from moving in the direction of the arrow in the figure unless a force stronger than the spring force is applied. However, if it is moved a little, it will turn in the direction of the arrow due to the toggle action of the spring 7. FIG. 4b shows the state shown in FIG. 4a rotated by 90°.
At this time, the paper feed tray 2 is pulled in the direction of the arrow in the figure by the spring 7. FIG. 4c shows a state in which the dowel 2b of the paper feed tray 2 is inserted into the hole 1b by the spring 7.

Conversely, if the sheet tray 2 is slightly rotated in the direction of the arrow as shown in FIG. 4b, it will be in the state shown in FIG. It will be in the state shown in Figure a (stored).

Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments. For example, although one spring is used in this embodiment, a plurality of springs may be used. Also, when installing the paper feed tray, 3
I used the dowel and hole shown in the picture, but you can use other methods as well. Also, although the spring and the positioning dowel are made to match, they do not have to be made to match.

In this embodiment, a paper feed tray is used, but a paper discharge tray may also be used.

In this embodiment, hole 1b and dowel 2b were used for positioning the paper feed tray, but dowel 2b was made longer than dowel 2a, and dowel 2b was first aligned with hole 1b.
After the paper input tray is positioned, dowel 2
You may also make it so that a goes into the hole. By doing so, the mounting can be performed reliably. At this time, it goes without saying that the dowel, hole, etc. should be tapered to make it easier for the dowel to fit into the hole.

[Effect of idea]

As explained above, by using a spring in the tray device, the tray can be completely inserted, there will be no installation defects, and the tray can be installed simply by raising it.

Furthermore, in this invention, the spring has a toggle characteristic, so when the tray is installed, the spring force acts in the installation direction, and when the tray is stored, the spring force acts in the storage direction from the middle, so the tray Switching can be done smoothly, and the installed state and stored state can be maintained reliably.

In addition, by adopting the configuration as in this embodiment,
The tray can be integrated with the main body and can be folded down when not in use, saving space.

Furthermore, when it comes to personal copying, etc., it is conceivable to move the copying machine, but by integrating the tray with the main body, there is no fear of losing the tray when moving.

Claims (1)

[Claims for Utility Model Registration] In a tray device that can be freely inserted into the main body of an image forming apparatus and that can select between a non-use state in which the insertion is released and a use state in which it is inserted, a support means having a support pin 6 and a groove 2c, which is rotatably and slidably supported on the main body, and which allows the tray to be in a substantially vertical position when not in use, and to be in a substantially horizontal position when in use; fitting means 1a, 2a, 1b, and 2b that engage the apparatus main body and the tray in a fitted state to hold the tray in a substantially horizontal position; one end engages with the apparatus main body and the other end engages with the tray; When in use, the tray is urged in a substantially horizontal direction, but when the tray is rotated, the other end acts to urge the tray into the vertical position. A tray device comprising a toggle spring 7.
