Abstract

PURPOSE:To obtain a confirming mechanism easy to insert an original and easy to confirm the position of insertion by providing an index to position the tip of the original to a specified position of an original guide and exposing the index part of the original guide. CONSTITUTION:A notched part 11 is formed in a part of armoring cover 9 that covers near an original insertion aperture 1 to expose a part of underlying original guide 6, and an index that forms an positional reference for inserting an original 3 is provided in the exposed part of the original guide 6. When an original is inserted until the tip of the original arrives at the position of index in the exposed original guide 6 from the original insertion aperture 1 by matching the side end of the original 3 with a reference guide 2, an original presence sensor detects the original. When a starting button is depressed, loaded originals 3 are sent out successively. As th notched part 11 is formed at the tip of the armoring cover, the original 3 can be inserted not only from the front of the original insertion aperture 1, but also from the notched part 11 in the direction shown by the arrow mark.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a document set in which it is possible to easily check whether a document is set in a predetermined position in a recording device such as a facsimile, printer, or electrophotographic copying machine. It concerns a confirmation mechanism.

<Prior Art> In a facsimile machine, when a document is inserted to a predetermined position, a document presence/absence sensor detects this.

After that, when the start button of the apparatus is pressed, the stacked originals are separated from the top and sent out one by one, and are transported at a constant speed by the reading platen roller.

In this case, if the document is not inserted to a predetermined position, the document presence/absence sensor cannot detect the document, and the apparatus will not operate even if the meta 2-to button is pressed. On the other hand, if the originals are inserted too deep, the stacked originals will not be separated and will be fed in duplicate by the reading platen roller.

For this reason, conventionally, in order to check whether or not the original has been inserted to a predetermined position, an indicator 12 is placed on the original guide 6 as shown in FIG.
111 is provided on the exterior cover 9 that covers the upper part of the indicator.
! A confirmation window 13 is provided, and it is confirmed by looking through the confirmation window 13 whether or not the original has been inserted to the index position.

<Problems to be Solved by the Invention> However, since the confirmation window 13 is provided on the exterior cover 9, in order to confirm the insertion state of the document through the window 13, the operator must stand up from his chair and move directly above the device. You have to look at the index position from the front, and if you don't think about the timing, the index 12 will be dark and difficult to check.Furthermore, when inserting the document, you will have to insert it from the front of the insertion slot. was there.

The present invention relates to a completely new technology developed to solve the above-mentioned conventional problems, and its purpose is to provide a document set confirmation mechanism that allows easy insertion of a document and easy confirmation of the insertion position. This is what we intend to provide.

<Means for Solving the Problems> One means for solving the above problems will be explained using a facsimile machine as an example.

FIG. 1 is an explanatory diagram of a document transport system of a facsimile machine incorporating a mechanism according to an embodiment of the present invention. When the document 3 is inserted while aligning the document 3 with the reference guide 2, the document presence/absence sensor 4 is pushed down and detects that the document 3 has been inserted. Then press the start button on the device (
When the pickup roller 5 is pressed (not shown), the pickup roller 5 descends and rotates, working in cooperation with the document guide 6 to separate the placed document 3 sheet by sheet from above and send it out to the right side of the drawing. The sent out document 3 is passed through the reading platen roller 7, the supply guide b pressed against the lower and upper parts of the reading platen roller 7 by springs a, and the ejection guide d attached to the ejection stay C, respectively, to the reading platen opening, - While being conveyed at a constant speed around the rough surface, image information is read by a small sensor 8, and the outer cover 9
The original document is discharged from a document discharge port IO provided in the document output port IO.

Further, as shown in FIG. 2, the exterior cover 9 is configured such that a notch 11 is formed in a portion covering the vicinity of the document insertion slot 1 so that a portion of the document guide 6 located below is exposed. An index 12 serving as a position reference for inserting the original 3 is provided in the exposed portion.

Note that the indicator 12 is provided at a position where the minimum width document 3a that can be conveyed by the apparatus is placed.

<Operation> Next, the case where a document is set in the facsimile machine configured as described above will be described.

When the original 3 is inserted through the original insertion slot 1 with its side edge aligned with the reference guide 2 until the leading edge of the original reaches the exposed index position of the original guide 6, the original presence/absence sensor 4 detects the original 3. After that, when the start button is pressed, the placed originals 3 are sent out one by one.

Furthermore, in the above configuration, since the notch 11 is formed at the tip of the exterior cover 9, the document 3 can be inserted into the document insertion slot.
Not only from the front, but also from the notch 1 as shown in Figure 3.
It is also possible to insert from 1 in the direction of the arrow in the figure.

<Example> In the above explanation, the one-side reference is used to guide one side of the placed document, and the upper separation method is used to separate one sheet at a time from the top. The same effect can be obtained by using the lower separation method.

<Effects of the Invention> As described above, the present invention provides an index for positioning the leading edge of a document at a predetermined position on the document guide, and is configured so that the index portion of the document guide is exposed, so that the index It can be seen not only from above but also from the front or side of the device. Therefore, when setting a document at the index position, there is no need to look down from directly above the device as in the conventional case, and there are no problems such as the index portion being dark and difficult to see, and it is possible to easily and reliably confirm that the document is set. This allows the operator to set the original f+! It is possible to read documents from the front of the device while sitting on a chair, and when inserting a document, it can be inserted not only from the front of the insertion slot as in the past, but also from the side of the notch, which provides excellent operability. It has the following.
