However, in the former mounting method, there is a danger that an operator may pinch his hand between the lower edge of the facsimile machine and the upper edge of the deck.

In the latter method, the facsimile is laid down, which is difficult for a user to carry out.

The present invention has been made in consideration of such a problem in the conventional combination, and provides an optional device that allows a user to easily and safely install the optional device under an apparatus body such as a facsimile machine. The purpose is to do.

[0008]

According to the present invention, when an elastic member is disposed on an upper surface and is combined with an apparatus main body, the elastic member is brought into a state in which an upper portion abuts on a bottom portion of the apparatus main body, and the apparatus main body is formed. This is an optional device that exerts a biasing force that lifts the upward.

Further, the present invention further has a lock means which can lock both the devices simply by pushing down the option device when the device main body is combined with the optional device.

[0010]

According to the present invention, when the optional device is first placed on the floor and placed thereon while holding the lower portion of the device body by hand, the elastic member present on the upper surface of the optional device becomes
Since the upper portion comes into contact with the bottom of the device main body and lifts the device main body upward, the device main body is placed on the optional device while slightly rising from the optional device. As a result, when the operator pushes down the apparatus main body from above with his / her hand, the operator can completely combine the two without being caught between the apparatus main body and the optional device.

Further, when assembling the optional device to the apparatus main body, the locking means automatically locks both apparatuses only by pushing down the apparatus main body.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the optional device according to the present invention. In the case of the present embodiment, the deck 1 as an example of the optional device supplies a large amount of sheets to the copying machine body 2. That is, the deck 1 has a box shape, and the upper wall 1a is formed slightly inside the upper edge 1b. Inside the lower part of the upper wall 1a, a cassette for storing a large amount of paper, a paper feed roller, and the like are incorporated (not shown). Reference numeral 1c denotes a slit formed on one side of the upper wall 1a for feeding a sheet to the copying machine main body 2. Six compression springs 3 are arranged on the upper wall 1a. In the vicinity of the upper end edge 1b on the right side in the drawing, two holes 4 for penetrating screws are formed.

On the other hand, the copying machine main body 2 has
The skirt 2a is slightly recessed inward, and its hem 2a is fitted into the upper edge 1b of the deck 1. Further, two screw holes 5 are formed in the skirt portion 2a on the right side in the drawing.

Next, a method of combining the copying machine main body 2 and the deck 1 in the above embodiment will be described.

First, an operator places the deck 1 on the floor. Then, the copying machine body 2 is lowered onto the upper wall 1a of the deck 1. At this time, the work is easier if the bottom wall of the copying machine body 2 is supported by hand. Then, the bottom wall of the copying machine main body 2 is placed on a spring 3 attached to the upper wall 1a of the deck 1. As a result, the copying machine body 2 can be placed on the deck 1 even if the worker does not support the copying machine body 2. At this time, since there is a gap between the bottom wall of the copying machine main body 2 and the upper edge 1b of the deck 1, there is no need to worry about the hand being pinched between them.

Therefore, the operator presses the upper side of the copying machine body 2 by hand, and fits the skirt 2a of the copying machine body 2 into the upper edge 1b of the deck 1 against the repulsive force of the spring 3. go. With the left hand holding the copier main body 2 in such a manner, the screw 6 is passed through the hole 4 and screwed into the screw hole 5 using a driver with the right hand, and the copier main body 2 is placed on the deck 1. Combine to

As described above, since the copying machine main body 2 can be placed on the deck 1 while being slightly lifted by the spring 3, there is no danger of catching hands.

FIG. 2 is a perspective view showing another embodiment of the present invention.

In this embodiment, a hook is used in order to save time for screwing the screw 6. Optional device 1
The rod 7 is rotatably bridged to the upper edge 1b of the rod. Two hooks 8 are fixed to the rod 7 in a state of being erected.
The holding plate 9 is fixed in the horizontal direction. Further, a compression spring 10 is provided between the holding plate 9 and the upper wall 1b. That is, the spring 10 constantly urges the holding plate 9 upward. Therefore, the hook 8 is urged to rotate a predetermined amount in the counterclockwise direction in the drawing. Further, the end of the rod 7 slightly projects outside the deck 1, and an elliptical handle 11 is fixed thereto.

On the other hand, a concave portion (not shown) is formed in the bottom wall of the copying machine main body 2 for engaging the hook 8 thereof.

When such a deck 1 is used, the copying machine main body 2 is gradually lowered from above the deck 1 and placed on the spring 3 as in the case of FIG. Then, when the copying machine body 2 is pressed from above by hand, the bottom wall of the copying machine body 2 descends while slightly rotating the hook 8 clockwise, and finally the projection of the hook 8 Thereby, it enters into the concave portion of the bottom wall and is locked. Thus, the copying machine main body 2 is combined with the deck 1.

When removing the copying machine main body 2 from the deck 1,
Turn the handle 11 clockwise by hand. As a result, the hook 8 rotates clockwise against the urging force of the spring 10, and the projection of the hook 8 comes off the concave portion of the bottom wall of the copying machine main body 2. Then, since the spring 3 always pushes the bottom wall of the copying machine body 2 upward, the copying machine body 2 naturally lifts up. Therefore, the operator only has to put his hand under the copier 2 and lift it.

As described above, in this embodiment, the copying machine body 2
By simply pressing down, it can be easily combined with the deck 1.

Incidentally, the apparatus main body in the present invention includes:
Not limited to the copying machine, any other device such as a facsimile and a printer may be used.

The optional device of the present invention is not limited to the deck, but can be applied to other optional devices.

The elastic member of the present invention is not limited to a compression spring, but may be a leaf spring or another member having elasticity. The material is not limited to metal, but may be plastic or the like.

The locking means of the present invention is not limited to a hook, a spring, or the like, and other locking means may be used. In short, when the apparatus main body is combined with the optional apparatus, the locking means can be locked to the apparatus main body.

[0029]

As apparent from the above description, according to the present invention, when the elastic member is arranged on the upper surface and assembled,
Since the elastic member comes into contact with the bottom of the apparatus main body at the upper portion and exerts an urging force for lifting the apparatus main body upward, the operator can manually move the elastic body between the apparatus main body and the optional device. The advantage is that you do not have to worry about being pinched.

Further, according to the present invention, when the apparatus main body is combined with the optional apparatus, the apparatus further includes a locking means which can lock both the apparatuses by simply pushing down the optional apparatus. It can be more easily realized.
