However, in the former assembling method, there is a risk that an operator may pinch his / her hand between the lower edge of the facsimile device and the upper edge of the deck.

Further, the latter method requires the user to lie down the facsimile, which is difficult for the user to carry out.

In consideration of the problems in the conventional combination, the present invention provides an optional device which allows a user to easily and safely incorporate the optional device into the lower side of a device body such as a facsimile device. The purpose is to do.

[0008]

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

Further, the present invention further has a lock means for locking both devices by simply pushing down the option device when the device body is assembled to the option device.

[0010]

According to the present invention, when the optional device is first placed on the floor and the lower side of the device main body is placed on the floor while being held by hand, the elastic member existing on the upper surface of the optional device becomes
Since the upper part is in contact with the bottom part of the device body and the device body is lifted upward, the device body is placed on the option device in a state slightly lifted from the option device. As a result, when the operator pushes down the apparatus body from above with his / her hand, the operator can completely combine the apparatus body and the option device without getting his / her hands caught.

Further, when the optional device is assembled to the device main body, the locking means automatically locks both devices by simply pushing down the device 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 an option 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 paper to the copying machine main 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 side of the upper wall 1a, a cassette for storing a large amount of paper, a paper feed roller, etc. are built in (not shown). Reference numeral 1c is a slit formed on one side of the upper wall 1a for feeding the paper to the copying machine main body 2. Six compression springs 3 are arranged on the upper wall 1a. Further, two holes 4 are formed in the vicinity of the upper edge 1b on the right side of the drawing for allowing a screw to pass therethrough.

On the other hand, the hem 2a of the copying machine main body 2 is
It is slightly recessed inward, and its hem portion 2a is adapted to be fitted in the upper edge 1b of the deck 1. Further, two screw holes 5 are formed in the skirt portion 2a on the right side of 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, the 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, it is easier to work 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 the spring 3 attached to the upper wall 1a of the deck 1. As a result, even if the operator does not support the copying machine main body 2, the copying machine main body 2 is placed on the deck 1. At that 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 pinching a hand between them.

Therefore, the worker presses the upper side of the copying machine main body 2 by hand and fits the hem 2a of the copying machine main 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 copy machine main body 2 in that way, use a screwdriver with the right hand to insert the screw 6 into the hole 4 and screw it into the screw hole 5 to place the copy machine main body 2 on the deck 1. To combine.

As described above, the main body 2 of the copying machine can be placed on the deck 1 in a slightly floating state by the spring 3, so that there is no danger of pinching the hand.

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

In this embodiment, a hook is used in order to save the trouble of screwing the screw 6. Optional device 1
A rod 7 is rotatably connected to the upper edge 1b of the rod. Two hooks 8 are fixed to the rod 7 in a standing state.
Further, the holding plate 9 is fixed in the horizontal direction. Further, a compression spring 10 is arranged between the pressing plate 9 and the upper wall 1b. That is, the spring 10 constantly urges the pressing plate 9 upward. Therefore, the hook 8 is biased to rotate counterclockwise in the drawing by a predetermined amount. Further, the end of the rod 7 is slightly projected to the outside of the deck 1, and an elliptic handle 11 is fixed thereto.

On the other hand, the bottom wall of the copying machine main body 2 is formed with a recess (not shown) in which the hook 8 is locked.

When such a deck 1 is used, when the main body 2 of the copying machine is gradually lowered from above the deck 1, it is placed on the spring 3 as in the case of FIG. Therefore, when the main body 2 of the copying machine is pressed from above by hand, the bottom wall of the main body 2 of the copying machine descends while rotating the hook 8 slightly clockwise, and finally the projection of the hook 8 is pushed by the force of the spring 10. Is inserted into the recess of the bottom wall and locked. As a result, 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 is disengaged from the bottom wall recess of the copying machine main body 2. Therefore, since the spring 3 constantly pushes the bottom wall of the copying machine body 2 upward, the copying machine body 2 naturally lifts upward. Therefore, the operator may put his / her hand under the copying machine unit 2 and lift it.

Thus, in this embodiment, the copying machine main body 2
You can easily combine it with Deck 1 simply by pressing.

The apparatus main body in the present invention is as follows.
Not limited to a copying machine, any other device such as a facsimile or a printer may be used.

Further, the option device according to the present invention is not limited to the deck but can be applied to other option devices.

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

The locking means of the present invention is not limited to hooks, springs, etc., and other locking means may be used. In short, when the device body is combined with the optional device, it can be locked to the device body.

[0029]

As is apparent from the above description, according to the present invention, when elastic members are arranged on the upper surface and are combined,
The elastic member exerts an urging force that lifts the apparatus main body upward with the upper portion abutting on the bottom of the apparatus main body, so that the operator can place a hand between the apparatus main body and the optional device. It has the advantage that you do not have to worry about being pinched.

Further, according to the present invention, when the main body of the apparatus is combined with the optional apparatus, the apparatus further has a locking means capable of locking both apparatuses by merely pushing down the optional apparatus. Therefore, the combination of the main apparatus and the optional apparatus can be combined. It can be realized more easily.
