Abstract

PURPOSE:To obtain accurately and easily a copy having a binding margin from an original which is set as normal, only with the operation of a knob by providing the binding margin setting knob. CONSTITUTION:In case of a copy which does not require a binding margin, the original is matched to a positioning guide 21, and a platen cover 13 is allowed to fall, and copying is performed. In case of a copy requiring a binding margin, a binding margin setting knob 20 is moved for an extent corresponding to the set binding margin after falling of the cover 13. In accordance with this movement, slide plate 14, an original retaining member 15, and the original are moved for the same extent accurately as one body. Since a guide depressing projection provided at the front end of the cover 13 presses the guide 21 downward before movement, the member 15 and the original are moved smoothly without hindrance. Copying is performed thereafter, and thus, the copy having the binding margin in one side is obtained accurately.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document moving device used for making copies having a binding margin.

[Prior art]

Conventionally, when making copies with a binding margin, as shown in Figure 1, the original (3) is shifted and centered on the original alignment guide (2) provided along one edge of the platen glass (11). However, such a set is not supported by the guide (
Since 2) has a step, it is not only difficult to set the cent itself, but also extremely difficult to set the stitching amount.

[Purpose of the invention]

The present invention is intended to solve the problems of the prior art, and its purpose is to easily and accurately move an original by a set amount and to easily make copies with accurate binding margins. An object of the present invention is to provide a document moving device that can be manufactured.

[Structure of the invention]

In order to achieve the above object, in the present invention, the document guide provided on one side of the platen cover is made to be tiltable up and down, and the document guide side of the platen cover is provided with a protrusion that tilts the document guide downward when the lid is closed. By moving the binding margin adjustment knob provided on the outer wall of the platen cover, the document can be moved relative to the platen glass by the set binding amount together with the document holding member provided inside the platen cover. The configuration is such that

〔Example〕

The present invention will be specifically described below based on embodiments shown in the accompanying drawings. 2 is a perspective view of a platen cover incorporating the document moving device according to the present invention, FIG. 3 is a side view of the platen cover, FIG. 4 is a sectional view taken along line 1-1 in FIG. 2, and FIG. FIG. 6 is an explanatory side view showing the engagement relationship between the moving document guide and the guide protrusion guide, and FIG. 6 is a view taken along the line nu--u in FIG.

In Figures 2 to 4, 00) is the copying machine main body (11).
), and a platen cover (13) that can be opened and closed up and down at one end with a hinge (12) is disposed on the platen glass QOI. The platen cover (13) is provided with a slide plate (14) and a document holding member (15) whose upper surface is fixed to the slide plate 1 (14), and the slide member (14) is attached to both sides thereof. (14a) are guide grooves (14a) provided on both side walls (13a) of the platen cover (13).
6). Also, the document holding member (
15) has a paper holding surface rough enough to cause sufficient friction with the original (17).

(18) is the - side wall (1) of the platen cover (13).
This is a guide hole for setting a binding margin provided in 3a), and the guide hole (18) has a binding margin setting scale (19) on its upper surface. Further, (20) is a binding margin setting knob that is slidably installed in the guide hole (18), and the base end of the knob (20) is fixed to the negative side (14a) of the slide plate (14). ing. With this configuration, the binding margin setting knob (
20) and move it by the amount of adjustment, when the document alignment guide (21) described later descends, the slide plate (
14) The document (17) is accurately moved by the set binding amount via the document holding member (15).

Further, in FIGS. 5 and 6, reference numeral (21) is a document alignment guide that is attached to one end of the platen glass 0ψ, which is on the side in the direction of movement of the slide plate (14). ) has its top surface (21a) connected to the platen glass (+0) when the platen cover (13) is opened.
The original mating surface (21b) protrudes from the top surface (10a) of 1.
is formed. In addition, the document alignment guide (21) can rotate up and down around the pivot pin (22), and this rotation is caused by the guide pressing protrusion (23) provided on the lower surface of the tip of the platen cover (13) pressing the upper surface (21a). As a result, the guide surface (21b) is located below the top surface (10a) of the platen glass (101). (24) is a return spring, (25)
is an over-rotation prevention pin.

Next, a copying operation procedure using the document moving device having the above configuration will be described.

First, for copies that do not require a binding margin, move the original fFI (31) to the document alignment guide (
21), and then the platen cover (13) is lowered to the closed state to perform copying.

On the other hand, if a binding margin is required, close the platen cover (13) as described above, then turn the binding margin setting knob (2).
0) by the set binding margin. Along with this, the slide plate (14), document holding member (15) and document (I
7) is also set accurately and moved by the margin. In addition,
Before this movement, the guide pressing protrusion (23) provided at the tip of the platen cover (13) is pressed against the document alignment guide (2).
1) is roughly pressed downward, the document holding member (15) and the document (17) can move smoothly without being hindered. If a copy is made thereafter, a copy with a binding margin on the negative side can be made accurately.

〔Effect of the invention〕

As described above, according to the present invention, copies with a binding margin can be easily and accurately made simply by aligning the original with the original guide as usual and then operating the binding margin setting knob.
