Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a document loading device in a facsimile machine, a copying machine, etc.

2. Description of the Related Art Conventionally, in facsimile machines and the like, a document loading unit is provided in a document feeding section, documents are set on the document loading device, and the documents are sequentially fed by a document feeding mechanism.

The conventional document stacking device is provided with a pair of document guides that are movable, moves the pair of document guides according to the document size, and contacts both edges of the document.
The document is configured to be regulated by a pair of document guides and sent out in the correct orientation.

For this reason, only one size of original can be set on the document loading device, so after feeding one size of original, a different size of original must be set and fed, which makes the operation cumbersome. I become confused.

For example, in the case of facsimile, it is inconvenient that documents of different sizes cannot be sent consecutively, and
When sending unattended at night, only one size of original can be sent.

The present invention has been made in view of the above-mentioned circumstances, and its object is to provide a document loading device that can simultaneously set documents of different sizes and send them out in the correct posture.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic perspective view of a facsimile.
The originals set on the original stacking device 2 are sequentially fed to the transmitting section 4 by the feeding mechanism 3, and are ejected from the ejection port 5 when the sending is completed.

As shown in FIG.
A pair of document guides 7, 7 is provided so as to be slidable left and right via a guide pin 9, and is configured to slide left and right depending on the document size.

As shown in FIG. 3, the document guide 7 has an L-shape with a bottom plate 10 and side plates 11.
The inner surface 11a of the bottom plate 10 serves as a guide surface, and the bottom plate 10 has a thin part 10' and a thick part 10'' with the stepped part 10a as a boundary. The delivery side portion 10''a is an inclined surface, and the delivery side end surface 10''b has the same thickness as the delivery side end surface 10'a of the thin wall portion 10'.

That is, in the document guide 7, the bottom plate 10 has two stages, forming a guide surface 11a and an auxiliary guide surface 10a.

Then, the guide surface 11a and the auxiliary guide surface 10a
The distance L ₁ between the two types of originals to be set is 1/2 of the size difference (difference in width) between the two types of original sizes to be set.

For example, as shown in FIG.
The auxiliary guide surface 10a is configured to match the A4 size original when the auxiliary guide surface 10a matches the B4 size original.

If the pair of document guides 7, 7 are positioned as shown in FIG.
An A4 size original can be set between 0' and 10', and a B4 size original can be set between 10'' and 10'.

After the A4 size original is sent out, the B4 size original is sent out one after another.

At this time, the feeding side end surface 10''b of the thick portion 10''
is located at the same position as the sending-out end surface 10'a of the thin wall portion 10', so that B4 size originals can be sent out smoothly.

Therefore, two types of originals, A4 size and B4 size, can be set at the same time and sent out one after another.

Note that when setting and sending out one type of original, by sliding the pair of left and right original guides 7, 7 left and right, it is possible to set and send out documents ranging from B5 size originals to A3 size originals. I can do it.

The present invention is as described above, and a small-sized original is positioned and placed between the thin parts 10' and 10' of the pair of original guides 7 and 7 by the facing stepped parts 10a and 10a. Side plates 11, 11 with large-sized originals facing each other across the thick parts 10'', 10''
The document can be positioned and placed using
Since the feeding side end surface 10''b of the paper has the same thickness and the feeding height position of small-sized originals and large-sized originals can be made the same, originals of different sizes can be set at the same time and sent out in the correct orientation. It becomes a loading device.

Therefore, when used for facsimile, originals of different sizes can be successively sent out and transmitted, which simplifies the transmission work.

Further, since the pair of movably provided document guides 7 are simply formed into an L-shape by the bottom plate 10 and the side plates 11 having a thin wall portion 10' and a thick wall portion 10'', there is no need to provide a particularly complicated mechanism. The cost is reduced, and originals of different sizes can be set by a simple operation of moving the pair of original guides 7, 7.

[Brief explanation of the drawing]

The drawings show an embodiment of the present invention; FIG. 1 is a schematic perspective view of a facsimile, FIG. 2 is a plan view of a document stacking device, FIG. 3 is a perspective view of a document guide, and FIG. 4 is a schematic perspective view of a pair of document guides. It is a front view of the positioned state. 7 is a document guide, and 10a and 11a are guide surfaces.

Claims (1)

[Claims] 1 The bottom plate 10 and the side plates 11 form an L-shape, and the bottom plate 10 has a thick part 10'' on the side plate 11 side and a thin part 10' that is integrally continuous with this thick part 10'' via a step part 10a. In addition, the delivery side portion 10''a of the thick wall portion 10'' is an inclined surface, and the delivery side end surface 10''b thereof is the delivery side end surface 1 of the thin wall portion 10'.
A pair of document guides 7, 7 having the same thickness as 0a'
The document stacking device is characterized in that the thin wall portions 10' of the document stacking devices are arranged such that the thin portions 10' thereof are movable toward and away from each other so that documents of different sizes can be set at the same time.
