Description

[Detailed Description of the Invention] [Technical Field] The present invention is applicable to, for example, a copying machine, a facsimile machine,
The present invention relates to a sheet storage device attached to a printing press or the like, and particularly to a storage device that can store large-sized sheet materials without occupying much space.

[Prior art]

FIG. 1 is a side view of a copying machine capable of making large size copies such as A1 size and A2 size. Base 1
A tray 3 is attached to the copying machine 2 placed on the machine.

This tray 3 is designed to have a size that can accommodate large-sized transfer paper 4A discharged from the copying machine 2, is tilted downward, and is integrally provided with a curved or bent stopper 5 at the tip. ing. If the tray 3 is tilted steeply, the transfer paper 4A may gain momentum as it slides on the tray 3 and fly out of the tray 3, or the leading edge of the transfer paper 4A may come into contact with the stopper 5 and then fall onto the tray due to momentum or its own weight. It falls to the opposite side from 3 and falls off. Therefore, in order to prevent this from happening, the conventional tray 3 is sloped relatively gently and the stopper 5 is also made long. In this way, since the tray 3 itself is large and has a small inclination angle with respect to the horizontal plane, the distance L from the mounting position of the tray 3 to the tip of the stopper 5 is inevitably long, and the area occupied by the tray 3 is large, which is disadvantageous in terms of space. It was hot.

〔the purpose〕

SUMMARY OF THE INVENTION It is an object of the present invention to provide a sheet storage device that eliminates the drawbacks of the prior art, occupies a small area, and prevents the sheet from buckling or falling off.

〔composition〕

In order to achieve this object, the present invention provides a tray that is steeply inclined downward from a mounting base, a stopper that receives the leading end of a sheet conveyed onto the tray, and a stopper that is located above the receiving surface of the tray. A plurality of anti-buckling members are provided in the tray, the one in the center is short and the ones on both sides are long, and the anti-buckling members are arranged relative to the tray so that the vertical direction of the anti-buckling members intersects the vertical direction of the tray. It is characterized by being located.

Next, embodiments of the present invention will be described using FIGS. 2 to 6.

As shown in FIG. 2, a tray 6 facing downward and steeply inclined is attached near the paper discharge port of the copying machine 2. As shown in FIG. A tray support bar 8 is installed between two brackets 7, 7 fixed to the copying machine 2, and the upper end of the tray 6 is rotatably supported by the tray support bar 8. The tray 6 is made of a thin metal plate, and a large size stopper 9A for receiving the large size transfer paper 4A is integrally formed at its lower end. Further, an oval size stopper 9B equipped with a magnet is magnetically attached to a predetermined position on the receiving surface of the tray 6, and the oval or medium size transfer paper 4B is received by this stopper 9B.

Two slope holding members 10, 10 are provided below the brackets 7, 7, and the steep slope of the tray 6 is maintained by tray supports 11 bent inwardly. . A hanging bar 12 is installed at the tips of the inclined holding members 10, 10, and is spaced apart from the receiving surface of the tray 6 by a predetermined height. On both sides of this bar 12, there are elongated buckling prevention members 13A made of wire whose tips extend above the stopper 9A for large size, and in the middle of the bar 12, the tips extend near and above the stopper 9B for small size. A short buckling prevention member 1 made of wire that extends up to
3B are each suspended rotatably.
When the anti-buckling members 13A and 13B rotate around the hanging bar 12, their lengths are adjusted so that they do not collide with the opposing stoppers 9A and 9B. When there is no transfer paper 4A, 4B on top, the tips of the buckling prevention members 13A, 13B are in contact with the receiving surface of the tray 6. Therefore, the anti-buckling members 13A and 13B are inclined at a larger inclination angle than the tray 6, or are suspended vertically, and their vertical direction (longitudinal direction) is the same as the vertical direction (longitudinal direction) of the tray 6. ) intersects with

When storing the large size transfer paper 4A on the tray 6, the small size stopper 9B is removed from the tray 6 as shown in FIG. Copy machine 2
The copied transfer paper 4A that comes out of the paper discharge port first comes into contact with the short buckling prevention member 13B, which is sloped more steeply than the long buckling prevention member 13A, and descends while sliding on the surface of the short buckling prevention member 13B. , interposes between the tray 6 and the tip of the short buckling prevention member 13B. Then, the transfer paper 4A slides along the receiving surface of the tray 6, and then gets inserted between the tray 6 and the tip of the elongated buckling prevention member 13A, and stops when the tip comes into contact with the stopper 9A. If another transfer paper 4A is already stored on the tray 6, this transfer paper 4A is
The buckling prevention members 13B and 13A are successively inserted between the buckling prevention members 13B and 13A.

As shown in FIG. 5, near the lower end of the transfer paper 4A accommodated on the tray 6 is a long buckling prevention member 13A.
The short buckling prevention member 13B is sandwiched between the short buckling prevention member 13B and the intermediate portion of the short buckling prevention member 13B in a state where the short buckling prevention member 13B is slightly pressed at its leading end and its middle portion is pressed slightly by the leading end of the short buckling prevention member 13B. The large-sized transfer paper 4A is relatively heavy and falls at a relatively high speed toward the stopper 9A, so when it collides with the stopper 9A, a buckling phenomenon occurs particularly from the center to the lower end of the transfer paper 4A. easy. If the long buckling prevention member 13A and the short buckling prevention member 13B of different lengths are used together as in this embodiment, while the transfer paper 4A reaches the stopper 9A, the short buckling prevention member 13B The falling speed of the transfer paper 4A is significantly reduced by the sliding resistance, the interruption resistance between the tray 6 and the short buckling prevention member 13B, and the interruption resistance between the tray 6 and the long buckling prevention member 13A. Furthermore, the leading edge and center portion of the transfer paper 4A are buckling prevention members 13A and 13B, respectively.
Since it is pressed against the tray 6 by the transfer paper 4A, it is possible to effectively prevent the transfer paper 4A from buckling and falling off from the stopper 9A.

When storing an oval or medium size transfer paper 4B in the tray 6, an oval size stopper 9B is magnetically attached to a predetermined position on the tray 6. Tray 6
It is convenient if an index indicating the mounting position of the stopper 9B is attached in advance by printing on the receiving surface of the stopper 9B. The copied transfer paper 4B slides down along the receiving surface of the tray 6, gets caught between the tray 6 and the tip of the buckling prevention member 13B, and comes into contact with the stopper 9B and stops. Small or medium size transfer paper 4
Since paper B is light in weight and does not fall so fast, the falling speed is reduced by the interruption resistance between the tray 6 and the anti-buckling member 13B, and the vicinity of the leading end of the transfer paper 4B falls onto the anti-buckling member 13B. Since it is pressed against the tray 6 side by the screws, it is possible to effectively prevent buckling and falling off.

FIG. 6 is a diagram showing a modification of the tray 6 and the stopper 9. The tray 6 is formed by combining small-diameter rods at predetermined intervals to form a slatted shape so as to receive the transfer papers 4A and 4B, and the rods have elasticity. The stopper 9 is a plate-shaped member made of synthetic resin or the like, and has two or more engaging recesses 14 provided at the side end facing the tray 6 at intervals slightly narrower than the intervals between the bars of the tray 6. When attaching the stopper 9 to the tray 6, the bars of the tray 6 are brought together slightly as shown by the broken arrows, and after fitting into the engagement recess 14 of the stopper 9, the bars are released. Then, the stopper 9 is elastically supported by the tray 6 due to the restoring force of these bars. When the stopper 9 is to be removed, the bars of the tray 6 may be brought together inwardly and the stopper 9 may be removed in this state. This removable stopper 9 is mainly used as a stopper for oval size,
It may also be used as a stopper for large sizes.

In the above embodiments, the storage device for copied transfer paper of a copying machine has been described, but the present invention can also be applied to, for example, facsimile machines, transfer paper of printing machines, manuscripts, etc.
It can also be applied to storage devices for printed matter, etc.

〔effect〕

Especially large sheet-like objects are relatively heavy.
Since the falling speed is high, buckling tends to occur from the center to the lower end of the sheet when it collides with the stopper. In addition, especially when the tray is steeply inclined with a large sheet-like object, both end portions of the sheet-like object may be bent toward the opposite side of the tray.

Therefore, in the present invention, among the buckling prevention members having different lengths, a short buckling prevention member with a short length is arranged in the center, and long long buckling prevention members are arranged on both sides. Therefore, even if the sheet-like object is large in size, before its tip collides with the stopper, the falling speed is reduced by the sliding resistance with the short buckling prevention member and the long buckling prevention member, etc. Since the sheet member is supported at at least three locations, namely the central short buckling portion and the long buckling prevention members on both sides, the buckling phenomenon can be effectively prevented. In addition, since long anti-buckling members are placed on both sides, even if the tray is tilted steeply, the ends of both sides of a large sheet member will not bend toward the anti-buckling member. Objects can be stored in a flat state. Therefore, the area occupied by the tray can be made much smaller than that of the conventional tray, which is very advantageous in terms of space.
