Description

[Detailed description of the invention] The present invention is an automatic document feeder that automatically transports the original set in the paper feed section to the exposure section, and then ejects the original onto the exit tray. This relates to a take-out device.

Conventionally, it was thought that when the document eject button on an automatic document feeder was pressed, the bottom plate of the output tray would lift up and the original would be removed from the output tray, but the document guide did not move and only the bottom plate was lifted. The disadvantage is that the distance between the document guide and the raised bottom plate is narrow, making it difficult to remove the document.

The present invention provides a paper feed section for setting documents at the top of the document feeder, a paper output tray is provided below it, a bottom plate of an L-shaped document placement member is placed inside the paper output tray, and a A square-shaped document guide base is provided on the top of a vertical plate protruding from one end of the bottom plate, parallel to the bottom plate.
A shaft is fixed to the upper end of the vertical plate, and the document placement member is attached so as to be able to rotate upward around the shaft, and the document is taken out by grasping the document guide and lifting the document placement member upward. This method eliminates the drawbacks of the conventional method.

Next, each embodiment of the present invention shown in the accompanying drawings will be described in detail. FIGS. 1 and 2 show a first embodiment of the present invention, in which A is a document conveyance type copying machine and B is an automatic document feeder mounted on the contact glass on the upper surface of the copying machine. At the top of the automatic document feeder B, there is provided a paper feed section 1 for setting documents, and below the paper feed section 1 there is provided a paper discharge tray 2. 3 is the document placement member and the bottom plate 3
A mold locking portion 3b is integrally formed at one end of the a, and a shaft rod 3c is fixed to the upper end of the mold locking portion 3b.
is arranged in parallel above the bottom plate 3a, and its base is fixed to the mold locking part 3d. Then, the shaft rod 3c is placed and set on a receiving plate 4 protruding from the upper edge of one side of the paper discharge tray 2. The bottom plate 3a is located opposite to the bottom of the paper discharge tray 2.

Next, the effect will be explained. When a document is set on the paper feed section 1 and a start button (not shown) is pressed, the document is conveyed onto the contact glass of the copying machine A as shown by arrow a and exposed to light, and then transferred to the paper output tray 2 as shown by arrow b. The document is sent to the document guide 3d, enters the document discharge tray 2, and is stacked on the bottom plate 3a. When taking out a document, when the tip of the document guide 3d is lifted, the center of gravity of the bottom plate 3a is further back, so the bottom plate 3a is lifted around the shaft 3c, and the document on the bottom plate 3a can be easily taken out with the other hand. be able to.

FIG. 3 shows a second embodiment of the present invention, in which side fences 3e are provided on both sides of the bottom plate 3a of the document placement member of the first embodiment.
is provided. The position of this side fence may be freely changed.

In the above embodiment, the stackability can be improved by preparing several types of document guides and bottom plates with different shapes depending on the document size. Further, by using the second embodiment, it is possible to prevent the originals from scattering to the left and right when the originals are taken out.

According to the present invention, a paper feed section for setting documents is provided at the top of the document feeder, a paper output tray is provided below it, and a bottom plate of an L-shaped document placement member is disposed within the paper output tray. , a square-shaped document guide base is provided on the top of a vertical plate protruding from one end of the bottom plate, parallel to the bottom plate, a shaft is fixed to the top end of the vertical plate, and the document placement member is moved upward around the shaft. The document mounting member is attached so that it can be rotated, and the document can be taken out by holding the document guide and lifting the document placement member, so that the gap between the document guide and the bottom plate does not become narrow when taking out the document, making it easy to take out the document. Further, the mechanism for lifting the bottom plate as in the conventional case is not required, and the mechanism is simplified.
