Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to a paper storage device, and more particularly to a paper storage device for storing paper such as recording paper or manuscripts for facsimile and copying machines.

BACKGROUND OF THE INVENTION In recent years, there has been a particularly strong demand for office machines such as facsimile machines and copying machines to be smaller and lighter.

As a result, in the past, the tray for storing recording paper or original documents was not built into the machine body, but was attached in a manner that protruded from the machine, and the machine body was generally made smaller accordingly.

As a result, even if the main body of the machine is made smaller, the installation space during use becomes larger due to the protrusion of a portion of the tray, and there is a drawback that the machine is not miniaturized in an actual sense.

Further, rolled paper such as thermal recording paper used in facsimiles and the like has a strong curling pattern, and has the disadvantage that it is difficult to store the paper in an orderly manner on a linear tray surface as in the past.

Recently, in response to the demand for downsizing of machine bodies, there has been a trend to reduce the outer diameter of paper while keeping the same length, and for this reason, methods have been adopted to make the core diameter as small as possible.

As a result, the curling becomes more noticeable, and there is a strong desire to develop a paper storage method that can deal with this.

FIG. 1 shows an example of facsimile loading equipped with a conventional paper storage device of this type.

A document tray 3 for storing documents 2 is provided on the left side of the main body 1 of the machine.

Further, on the right side of the machine main body 1, there is provided a recording paper tray 6 for storing the recording paper 5 fed out from the roll after being cut.

↓ As a result, even if the machine body was made smaller, there was a problem that the actual installation space could not be made smaller due to the protrusion of both trays 3 and 6.

In Fig. 1, the reference numeral 4 denotes an optical system for reading information from a document, 7 a thermal head for recording on thermal recording paper fed out from a roll, and 8 a thermal head for pressing the recording paper against a thermal head. A platen roller 9 transports the recording paper, a cutter 9 cuts the recording paper 5 into a predetermined length, for example, A4 length, and an electrical unit 10 includes a power supply device and the like.

In addition, if the trays 3 and 6 are forced to be installed in one side of the machine body 1, the re-drive system for originals and recording paper will be concentrated on one side, which will reduce the space efficiency inside the machine and complicate the drive system. This not only leads to a decrease in reliability, but also a significant increase in costs.

The present invention has been made in order to eliminate the above-mentioned conventional drawbacks, and by eliminating the paper ejection tray of the conventional configuration, the actual installation space itself can be reduced, and the mechanism can be made simpler. The purpose is to provide a paper storage device.

EXAMPLES Hereinafter, the present invention will be explained in detail based on examples shown in the drawings.

FIG. 2 illustrates an embodiment of the present invention, in which the members labeled with the same numbers as in FIG. 1 are the same members as in FIG. 1.

In this embodiment, as shown in FIG. 2, the protrusion of the storage tray 6 for the recording paper 5 is eliminated, and in its place a new storage tray 6' having a wedge-shaped groove is provided inside the machine.

This storage tray 6' is provided with a second blocking member 11 made of a plastic plate fixed to a frame (not shown) of the main body l.
A first blocking member (the first and second blocking members are not necessarily plates) is rotatably fixed to the lower end of the blocking member 11 by a pin 12 and is positioned downstream in the paper conveyance direction. It does not have to be a shape, for example, it may be made of a plurality of wires arranged in the vertical direction (in short, it is sufficient if it is a member that can prevent the movement of the recording paper).

A click mechanism (not shown) is provided between the main body and the first blocking member to lock the first blocking member in the state shown in FIG. When opened, it is locked by the lower outer case 1-1 of the main body 1 in the state shown by the dashed line.

When the first blocking member 13 is open, the ejected recording paper 5 moves along the first blocking member 13, so that it forms an ejection guide section.

When the length of the recording paper is short or, conversely, when it is not long, it is preferable to use the first blocking member B in the open state.

When the first blocking member 13 is closed (the state shown by the solid line in FIG. 3(A)), a loop-shaped record is formed between the upper end of the first blocking member 13 and the outer upper case 1-2 of the main body 1. A gap 1-3 is formed that is sufficient for the paper 5 to be discharged.

In addition, when the first blocking member is closed, the first and second blocking members form a storage section with a V-shaped cross section, but it does not necessarily have to be V-shaped, and both members form a storage section at the lower end. The walls may be slightly apart.

Further, when the first blocking member 13 is closed, the angle formed by the recording paper 5 and the blocking member 13 is such that the recording paper 5 is
It is sufficient that the angle is obtuse so that it comes into contact with and is smoothly guided into the storage section (downward).

In the case of this embodiment, since the distance between the recording paper 5 leaving the paper guide path 14 and reaching the second blocking member 13 is short, the angle formed by the recording paper conveying direction and the second blocking member 13 is also small. It is an obtuse angle.

The leading edge 5' of the recording paper 5 (see FIG. 3 (A)) is introduced into the wedge-shaped groove of the storage tray 6', and the recording paper 5 is continuously fed out at the same time as it is gripped at the bottom of the groove. By using the elasticity of the paper to invert the rear end and send it out of the device, storage is completed with the leading end of the recording paper 5 being held inside the machine and the rear end hanging down outside the machine. ,
The operation can be linked to storing the next recording paper.

The series of operations described above will be explained with reference to FIGS. 3 to 6.

FIG. 3(A) is an explanatory diagram of the recording section of the facsimile apparatus of the present invention.

First, the thermal recording paper 5 wound into a roll is heated by the thermal head 7 in accordance with the impression, and image information is recorded on the surface -J2 of the recording paper 5.

Thereafter, the recording paper 5 is conveyed by the rotation of the platen roller 8, passes through the cutter 9, and its tip is wedge-shaped.
Alternatively, it is introduced into a tray 6' having a V-shaped groove.

At this time, the tip 5' becomes wedged in the bottom of the groove due to the wedge effect, as shown in FIG. 4.

When the recording paper is continuously fed out in this state, the gap 1-
3, the recording paper is discharged in a loop shape, and finally it curls and hangs down outside the machine body 1 as shown in FIG.

In this state, when the cutter 9 operates and cuts off the rear end of the recording paper, the recording paper hanging outside the machine as shown in Fig.
It is reversed in the direction of the arrow due to its own weight, and reaches the state shown in FIG. 6 in which the tip end 5' is held in the wedge-shaped groove i and the rear end hangs down outside the machine.

This series of operations of the recording paper 5 is repeated, and the recording sheets accumulate in the tray 6'.

If configured as in this embodiment, multiple recording sheets]・
The information side can be arranged in the order of pages and stored in the tray 6', which not only improves the installation space but also greatly improves operability such as handling of recording paper. effective.

Also, the first blocking member 13 forming this wedge-shaped groove
Open as shown in the chain line in Figure 3(B) and remove the external tray 11.
By connecting the two, there is also the effect that more recording paper sheets can be stored.

Further, unlike the conventional method of placing recording paper on a tray, the tray holds only the leading edge, so it is possible to store even extremely long recording paper.

In addition, since the paper can be introduced into the tray immediately after passing through the cutter, there is no need for paper ejection rollers, making the mechanism simple and expected to significantly reduce costs and improve reliability.

In addition, by opening a portion of the tray depending on the amount of recording paper stored and connecting an external tray, the structure can accommodate a large amount of recording paper.

In addition, the effect of making it easier to take out small pieces of paper contained in a receipt can also be obtained.

In the embodiment described above, only an apparatus that cuts continuous paper has been described, but it is of course applicable to an apparatus that uses pre-cut paper.

Effects As is clear from the above explanation, according to the present invention, by inserting the leading edge of the recording paper into the groove and inverting the trailing edge outside the machine so that it hangs down, the paper can be printed without protruding a special tray from the main body of the machine. The installation space of the machine can be significantly reduced,
Moreover, it is possible to store the recording paper in a well-aligned state regardless of the winding of the recording paper.
