Description

DETAILED DESCRIPTION OF THE INVENTION (1) Field of Industrial Application The present invention relates to an apparatus for storing a web of paper sent out from a computer printer in a fan-folded state. More specifically, the present invention relates to a lightweight, compact and compact device for folding and accommodating the output of a computer printer, which takes up little space on any desk space. Still more particularly, the present invention relates to an apparatus having an economical structure 2 for refolding and accommodating computer printouts in the same folding pattern as when they were delivered to the supply side of a printer.

(2) Prior art and paper folding devices are known and used in a wide range of applications. Typical applications include fan-folded paper or other forms of paper or printers. Alternatively, the data is fed to an equivalent device, printed and typically sent out from a computer. The data is processed at a screening speed. The feed paper is usually drawn from a carton or box to perform the printing operation. The paper is then fed through the output slot of the printer in a sorted or tangential manner and folded into a paper stacker or basket, but only if it has an odor or However, there are no commercially available or manufactured folding devices for personal computers or the like that are small and lightweight and do not require additional desk space or moving parts.

Most personal computers are used in gardens or offices, and these spaces are quite limited compared to the computer room designed for the computer and all its peripherals. Usually on one or two sides where the computer, monitor, keyboard and printer are against the wall! It is placed on a common desk or table with 2. Therefore, there is almost no space for the input of fan-folded paper, and there is also almost no space for equipment for processing the output from the printer below or around the desk. As a result, output is currently processed manually, which takes a lot of time and effort. In other methods, the output)
It is common practice to leave the Y exposed and collect the rear frame and fold it, but in this case there is a risk of damaging the output. Proposals have been made to eliminate the need for increased desk space, since the output from the printer requires additional space around or on the desk.
It does not solve the problem of output storage.

(5) Structure and Operation of the Invention According to the present invention, a paper folding device can be mounted directly on the printer in a manner that does not require additional desk space. If desired, the position of the printer can be raised to reduce the space required for the supply side carton storage below the printer. The present invention provides a simple 1-shaped member with a curved guide device 7 depending from a vertical rear part. This guide device accommodates the output of the printer and guides it through a curved path and downwardly toward the bottom of the L-shaped member forming the folded surface. Also in accordance with the invention, a proximal stop and guide device is provided which retains the wafers in the folded configuration in the carton or supply stack during refolding. The printer can be easily operated by simply manipulating the leading edge of the paper web printout.

(4) DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, a typical computer printer 1 is shown fed with a human-powered web 2 from a fan-folded stack of paper provided in the printer's supply 11111. As shown in the second figure, the folding section is designated by the symbol F. As is well known, 1 there are usually perforations in the side of the paper and the paper is driven in the printing mechanism 1 by a drive sprocket, indicated by the symbol.

However, it is within the scope of the present invention to use paper that does not heat the sprocket drive holes. If no drive sprocket is used, the paper is driven in the usual manner and by pressure rollers.

The paper folding device has a bottom part 7 forming a refolding surface.
An L-shaped folding member 4 is also constructed, which has a vertical rear part 5 with a slanted surface 6. bottom'@
7 has a shelf part 8 in the base direction, and a flat surface 9 in the base direction extending from the base of the bottom part 70 to the shelf part 8 is formed. An inclined proximal stop guide device 10 extends from the shelf B to the top of the notch 11 in the vertical rear part 5. Posts 12 are provided on both sides of the notch 110.

These posts hold a bin 15 on which a curved guide device 14 is suspended. The curved guide device 14 has a receiving edge 15 which is arranged to receive the leading edge LE of the output web 5 of the printer 1 as shown in the second figure and which has a curved path towards the delivery edge 16. Supported through.

In the embodiment shown in FIGS. 1 to 6, the delivery edge 16 of the curved guide device 14 is provided with a notch 18 and a swing flap 20 which is pivotably skinned by a rod 21. is provided. This flap is provided for public access and is not provided in the embodiments shown in FIGS. 7-10. Extending distally from the shelf 8 to the tip of the bottom 7 of the folding device is a flat surface 9, which serves as a refolding surface. This surface 9 has a tin line 27 extending at an upward angle from the shelf 8 towards the tip of the bottom 7. The depending flange 29 is located at the bottom most edge and is tightly attached to the end of the °C printer 1. The hanging post filter O is provided in the base direction of the bottom, that is, in the rear end, and is tightly attached to the end of the printer. In other embodiments, the bottom 7 could rest on top of the printer 1 or be provided with leg sockets to accommodate printers of various heights.

Referring now to Figures 2-6, a stack of folded papers S contained in a box B on the supply side of the printer is shown being fed into the printer. There is. The stack S is driven by a drive sprocket (D) and passes through the outlet into engagement with the receiving edge 15 of the curved guide member 14. It is well known in theory that the data printing operation can be performed at point H, and that holes can be provided in the 1111 section of the paper so that the paper can be driven by a pressure roller rather than a drive sprocket. The leading edge I, E of the exit web 5 is fed by hand into the receiving edge 15 of the curved guide device 14 and the exit edge 16 is also run out. At the exit edge, the leading edge LB is guided by a swing flap 20, as shown in FIG. As shown in Figure 1, the first folded part FU and the leading edge L are guided upward.
E projects towards the tip of the bottom 7 of the device. The leading edge can therefore be manipulated by hand and pushed back against the stop 10, as shown in FIG. The folding portion F U therefore descends onto the spline 27 at the tip of the bottom portion 7 . The rear folding section F D (which points downwards) falls towards the re-guiding device and the stop 10 due to the vehicle pressure. From this point onwards, the operation is completely automatic.

The purpose of the splines 27 is to fold the edges of the paper towards the edges of the flat surface 24 and force out the nitrogen between the folds, thereby giving the stack the same folded shape as it had on the supply side S of the box B. It is made to fold naturally.

If the first fold out of the printer is pointing downwards (for example, in the case of an FD), push this fold backwards and downwards. This allows F, l) to rest against the bottom of the folding guide 10' and extend the entire width across the rear part 5 of the L-shaped member, further eliminating the swinging flap. When the folding portion FD contacts the stop guide device 10, the leading edge 1. E is the spline 2 in the direction of the tip of the bottom part 7
Located above 7.

From now on, each folding part is automatically folded in the same folding pattern as was in box B on the supply side S of the printer.

(5) Effects The device of the present invention is small and compact, does not occupy much space, and has no moving parts. It is therefore very well suited for partial computers or terminals and printers used in homes and offices, and does not require additional space beyond that required by the equipment itself.

- Manually manipulate the printer enough to fold the last printed page when the print operation is finished. All pages printed separately from the refolded stack are then removed. It will be appreciated that the apparatus of the present invention can be used to process the entire length of a printer's output, and also to cut out printed pages while the printing operation is occurring.
