Description

[Detailed Description of the Invention] This invention relates to an auxiliary table in a sheet feeding device.

It is desirable that office equipment such as copying machines and facsimile machines occupy a small amount of space, and that the shape of the main body does not interfere with operator operation or passage.

However, for devices such as facsimile machines that are equipped with a sheet mounting table for recording sheets or originals, it is possible to reduce the size of the entire device in order to reduce the space it occupies. The tray has a structure in which it protrudes outward from the main body of the apparatus, and this protruding tray may actually become an obstacle to the operator's operation or passage. In order to solve this problem, a conventional tray is known in which a sheet mounting table (tray) is configured to be detachable from the apparatus main body, and is inserted into the apparatus main body only when the sheet mounting table is used.

However, the stated purpose of the above-mentioned tray cannot be achieved unless the tray is attached and detached each time it is used and after use. This ends up causing trouble for the operator.

In consideration of these points, for example, as shown in FIG. 1, due to the miniaturization of the apparatus, the extending portion of the sheet mounting table 2, which has a structure that protrudes outward from the apparatus main body 1, is attached to the main body 1. In contrast, a sheet mounting table has been proposed that includes an auxiliary table 3 that is foldable and openable.

This auxiliary table 3 can be folded away from the main body 1 of the machine, as shown by the chain line in FIG. It has various effects such as the space it occupies is reduced, the strength balance due to its shape is improved, and it is extremely easy to handle.

However, as is clear from Figure 1, this auxiliary table is shaped like a writing desk, so it is difficult for the operator to take notes or align the leading edges of sheets placed on it. be.

Although the above-mentioned auxiliary table 3 has the strength for placing sheets for its original purpose, if it is used for other purposes as mentioned above, its hinges etc. may be deformed or destroyed. It has been confirmed through experiments that this is the case. In order to solve these problems, an auxiliary table as shown in FIGS. 2 and 3 was previously proposed by the present invention.

The auxiliary tables 3 and 30 shown in FIGS. 2 and 3 are both configured to separate from the apparatus main body 1 when an overload of a predetermined value or more is applied thereto.

That is, the auxiliary table 3 shown in FIG. 2 has a hinge portion 3a formed in a crab-like shape,
An auxiliary table 3 configured to be elastically fitted onto a support shaft 4 horizontally suspended at the upper end of a sheet mounting table 2, so that the auxiliary table 3 can be opened/closed and attached/detached to/from the main body 1 of the apparatus. It is.

The auxiliary table 30 shown in FIG. 3 also has a pair of ears 31 and 32 formed on its base 30a.
(see FIG. 4), the engaging portion 51a of a pair of engaging members 51 and 52 is fixed to the lower surface of both sides near the end of the sheet mounting table 20. , 52a and the engaging portions 51a, 52a
, the support shaft 40 is inserted into each spring 9 from below.
The auxiliary table 30 is made up of a pair of locking members 61 and 62 that are elastically engaged by the elastic forces of 1 and 92, and the auxiliary table 30 can be opened/closed and detached from the main body 10 of the apparatus. be.

This auxiliary table 30 is different from the above-mentioned auxiliary table 3, which completely falls off and separates from the apparatus main body 1, so there is a concern that it may be damaged due to falling.
When the auxiliary table 30 is detached from the apparatus main body 10, the holding part 100 formed at the end of the sheet mounting table
By holding the support shaft 40, there is an effect that the auxiliary table 30 itself is prevented from falling.

In this way, the auxiliary tables 3 and 30 shown in FIGS. 2 and 3 separate from the main body of the device when they are overloaded, so that their hinges or support shafts are not affected by the overload. , the risk of destruction or deformation is eliminated. However, as mentioned above, although the configuration in which the auxiliary table is removable from the main body of the device is an extremely important means of protecting the auxiliary table and the main body of the device, the operator cannot notice this from the external appearance of the device. Therefore, there is a risk that the auxiliary table may be used as a desk without knowing that it will separate from the main body of the device.
In this case, the auxiliary table may appear to be in poor condition, or items placed there may fall, making the operator uncomfortable. Taking all of these points into consideration, the auxiliary table must be constructed so that it can be opened and closed freely and integrated with the sheet mounting table of the main body of the device, and that there is no risk of it being used for purposes other than its original purpose. , or a shape is desirable.

The purpose of this invention is to prevent the sheet mounting table from being used for purposes other than its original purpose in view of the various problems mentioned above, and to prevent the use of the sheet mounting table from being inappropriate if it is used for other purposes. The objective is to provide an auxiliary table that allows the operator to notice this.

If the above-mentioned auxiliary table is used for purposes other than its original purpose, such as as a writing table or a storage stand, there are ways to make the operator aware that the use is inappropriate, such as by checking the top surface of the auxiliary table. A warning display using irregularities, many small holes, or designs or letters is mainly used to appeal to the operator's eyes, and a sensor such as a micro switch, reed switch, or pressure-sensitive element is installed on the underside of the auxiliary table. A conceivable method would be to use an auditory means to detect the presence of an overload and notify the operator using a lamp or a buzzer. This idea is
The feature is that the overload on the auxiliary table is detected by the operator's sense of touch.

In other words, the purpose of this invention is that, for example, when an operator rests his or her hands or elbows on the auxiliary table or performs work such as aligning the head of the sheet on the auxiliary table, the auxiliary table will be The auxiliary table has a structure that either sinks into the sheet loading table or rotates slightly downward with respect to the sheet loading table, so that the operator can detect abnormal movement of the auxiliary table and prevent damage due to overload of the auxiliary table. The purpose is to prevent it.

This invention will be explained below with reference to an illustrated embodiment.

In FIG. 5, the reference numeral 10 indicates a main body of the sheet feeding apparatus, and the reference numeral 20 indicates a sheet mounting table which is substantially integrated with the main body 10 of the apparatus. As shown in FIG. 5, the auxiliary table 300 according to this invention has a
It is arranged so as to be foldable and openable with respect to the apparatus main body 10 by means of a hinge 400, and is configured as an extension of the sheet mounting table 20. By folding the auxiliary table 300 around the hinge 400 as shown in FIG. This eliminates the risk of this happening.

The hinge 400 is fixed to the end of an L-shaped bracket 401, as shown in FIGS. 6 to 8.

On the other hand, the auxiliary table 300 has a pair of ear pieces 301 and 302 facing each other (see FIGS. 6 and 9).
(see figure) are formed on both sides of the base end 300a, extending from the base end 300a.

The auxiliary table 300 has these pair of ear pieces 30
1,302, the sheet mounting table 20 is held in a state where both sides of the extending end of the sheet mounting table 20 are sandwiched.
Holes 21a and 22a drilled in both sides of the hole and holes 301 drilled in both ear pieces 301 and 302.
a, 302a (see Fig. 6), and insert a pair of brackets 4 into each of these holes.
By inserting the hinges 400 of No. 01 into the sheet mounting table 20, it is arranged to be foldable and openable with respect to the sheet mounting table 20.

In addition, each bracket 401 has its respective hinge 400 inserted into each of the above-mentioned holes, so that the respective base and the channel portion 20c (see FIG. 7) at the bottom of the extending end of the sheet mounting table 20 are connected to each other. , and are fixed in place by each screw 402. By rotating the auxiliary table 300 to the right in FIG. 5 about the hinge 400 from the folded position indicated by the chain line 300A in FIG. proximal surface 300b of
(See FIG. 9) correspond to each other via the buffer member 500, thereby reaching the open position shown by the solid line in FIG. The buffer members 500 are made of an elastic material such as rubber or cork, and several (three in the illustrated embodiment) are glued to the base end surface 300b of each recess 300c formed in the base end 300a of the auxiliary table 300. (See Fig. 9).

Therefore, in the above-mentioned auxiliary table 300 in the open position, one side of each buffer member 500 is
They are in contact with the extending end surfaces 20b of the sheet mounting table 20 (see FIG. 7).

Therefore, the auxiliary table 30 in this open position
If an overload is applied to the auxiliary table 300 as shown by the symbol W in FIG. 500 is compressed, the overload W is absorbed, and the auxiliary table 300
rotates slightly to the right about the hinge 400 in FIG. That is, the buffer member 500
immediately notifies the operator that the auxiliary table 300 cannot withstand the overload W due to being compressed by the overload W,
It serves to protect the auxiliary table 300 from damage.

As described above, since the auxiliary table provided by this invention can be opened and closed with respect to the sheet mounting table and is constructed integrally therewith, there is no fear that the auxiliary table will be damaged due to falling.

Further, even if an overload is accidentally applied to the auxiliary table, the buffer member notifies the operator that the load is too large, thereby eliminating the problem of damage. Furthermore, by providing the above-mentioned cushioning member, the impact caused by the collision with the sheet mounting table when the auxiliary table is opened is absorbed, so there is no impact noise or vibration caused by the impact, and the opening and closing of the auxiliary table is extremely quiet. become. This is extremely effective in extending the life of the hinge and auxiliary table.

Further, the base end of the auxiliary table is hinged to the extending end of the sheet mounting table, and when the auxiliary table is in the open position, the cushioning material provided at the base end is brought into contact with the extending end. As a result, except when a load is applied to the free end, it is fixed as an extension of the sheet loading table in the open position, preventing unnecessary rotation and preventing jamming of the inserted original. It can be prevented.

Note that a plurality of protrusions 303 are formed on the upper surface of the auxiliary table 300 in the above embodiment, and it is designed to prevent operations such as writing or aligning the head of the sheet from being performed on this upper surface. (See Figures 6 and 9).

Further, in the above embodiment, the auxiliary table is arranged with respect to the sheet mounting table using a hinge fixed to the bracket. A hinge 400A formed similarly to the hinge used when joining the band and the band may be used.

Furthermore, although the buffer member in the above embodiment is an elastic body such as rubber, for example, as shown in FIG. You may.

The buffer member may be fixed at the edge of the extending end surface of the sheet loading table, or it may be fixed from the sheet feeding device main body to the contact area between the sheet loading table and the auxiliary table. It may also be a protruding member (not shown).
