Abstract

PROBLEM TO BE SOLVED: To prevent a harmful influence caused by breakage overturn and movement, by converting the vibrational energy of an earthquake into kinetic energy for moving an image forming device. SOLUTION: Respective mats 8 and 9 are arranged in specific positions on both sides in the longitudinal and lateral directions, to which a printer 1 can be moved, and a framing member 10 and a floor driven member 11 are incorporated in the mats 8 and 9. The framing member 10 and the floor-driven member 11, which are in the mat 9 can be connected to the mat 8 and incorporated after the printer 1 is put in the mat 8. The printer 1 and the mats 8 and 9 are kept at a fixed distance and even if the printer 1 is moved because of the earthquake, its energy is absorbed so that the printer 1 is stopped, because it is surrounded by the respective mats 8 and 9. The respective mats 8 and 9 are provided with the framing member 10 and the floor driven member 11, not to be moved. Thus, even if the printer 1 placed on a 2000-sheet feeding deck 4 is moved because of the energy of the earthquake, the moving amount can be regulated within a prescribed dimension, so that the occurrence of a failure in blocking an evacuation route, etc., can be prevented.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-seismic member and an anti-seismic structure of an image forming apparatus having a large-capacity sheet feeding device having a movable wheel.

[0002]

2. Description of the Related Art The Great Hanshin Earthquake occurred in January 1995, causing many casualties. Thereafter, various seismic members for earthquake countermeasures have been commercialized.

As one example, an earthquake-resistant member used in an image forming apparatus as office equipment is a type in which a table-type image forming apparatus and a desk on which the image forming apparatus are mounted are connected to each other when an earthquake occurs. There is an earthquake-resistant member that fixes the image forming apparatus so as not to move due to the vibration.

[0006] FIG. 6 is a schematic explanatory view showing a use state of one example. In FIG. 6, reference numeral 1 denotes a desktop type printer, reference numeral 2 denotes a desk on which the printer is mounted, and reference numeral 3 denotes an anti-seismic fixing member having an adhesive surface on both the printer 1 and the desk 2.

[0005] For example, as an example of an actual product, a safety fastener "Samrock" of Lion Office Equipment Co., Ltd.
(Product name) etc. are commercialized.

[0006]

However, in the above-mentioned conventional example, although it is effective as a seismic member for a tabletop type image forming apparatus, for example, a two-stage deck type having legs such as casters, etc. This is not effective in the case of an image forming apparatus installed on a large-capacity sheet feeding apparatus. because,
The legs are originally attached to make them movable, so fixing them for earthquake countermeasures would destroy the function of being movable.

[0007] There is generally much more opportunity to move an image forming apparatus during installation or jam clearance of an image forming apparatus having a large-capacity paper feeder than to encounter an earthquake that cannot be known when it will come. As expected, fixing the image forming apparatus does not correspond to reality. Also,
If the image forming apparatus with the cuff is fixed, the vibration energy is completely received when an earthquake occurs, and the possibility that the image forming apparatus is damaged or overturned is more likely to occur. There was a problem.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems. This type of image forming apparatus is damaged or moved by an overturn or the like when an earthquake occurs, or the evacuation passage is closed. It is intended to provide means for preventing the occurrence of adverse effects such as the above.

[0009]

SUMMARY OF THE INVENTION Accordingly, the present invention provides the above-mentioned object by providing an anti-seismic cushioning member or an anti-seismic member image forming apparatus of any of the following items. What we are trying to achieve.

(1) A shock-absorbing member for an image forming apparatus, which is arranged around an image forming apparatus mounted on a floor and fixed on the floor.

(2) The shock-absorbing member for an image forming apparatus according to (1), wherein the shock-absorbing member has a shock absorbing member on the surface and a frame member on the inside.

(3) An anti-seismic shock-absorbing member for an image forming apparatus, which is installed between the image forming apparatus and a wall surface close to the apparatus so as to be attachable and detachable.

(4) The shock-absorbing member for an image forming apparatus according to the item (3), wherein the shock-absorbing member can also buffer a torsional force.

(5) An image forming apparatus with an anti-seismic member, wherein the means for preventing the movement of the crawler installed at the bottom of the large-capacity sheet feeding device of the image forming apparatus operates when an earthquake occurs.

(6) An image forming apparatus with an anti-seismic member, wherein the overturn prevention member installed at the bottom of the large-capacity sheet feeding device of the image forming apparatus operates when an earthquake occurs.

[0016]

According to the present invention as described above, when an earthquake occurs, the moving range of the image forming apparatus equipped with the large-capacity sheet feeding device with a leg is restricted, and the vibration energy of the earthquake is applied to the image forming apparatus. By installing a cushioning member that absorbs the shock, and by installing a leg stopper and a fall prevention member that operates when an earthquake occurs, the vibration energy of the earthquake is positively converted to the kinetic energy that moves the image forming apparatus, thereby reducing the impact of the earthquake By restricting the movement range to a narrow range without being received directly, it is possible to prevent the occurrence of adverse effects such as damage to the image forming apparatus, which requires an indispensable function, and blocking of an evacuation passage due to overturning or movement. It becomes possible.

The screw 17 attached to the 2,000-sheet feed deck 4 is a component made of a material such as rubber as a member for increasing the coefficient of friction with the floor attached to the bottom of the adjuster 15, and is used in this embodiment. In the case of Example 3, thirteen are provided.

Reference numeral 18 denotes a shaft of the caster 7, which is attached to the bottom of the 2,000-sheet feed deck 4. Reference numeral 19 denotes a stopper for preventing the movement of the caster 7, which is a plate-shaped sheet metal attached to the center axis of the shaft of the caster 7. Reference numeral 20 denotes an operation rod of the stopper 19, which can be protruded in the direction of the arrow. Reference numeral 21 denotes an acceleration detection sensor (hereinafter abbreviated as “G sensor”) for detecting acceleration in the vertical direction (weight direction), which is built in the 2,000-sheet feeding deck 4.

6 is rotated in the direction of the arrow to increase the friction coefficient increasing member 17.
Is more strongly in contact with the floor surface FL. By doing so, the frictional force with the floor surface FL is increased, so that the adjuster 15 plays a role of not only preventing falling but also preventing movement.

The G sensor 21 activates the actuator 23 when detecting a longitudinal wave of the earthquake. As a result, the operating rod 20 moves in the guide 24 and protrudes in the direction of the arrow to push the stopper 19, so that the stopper 19 acts to move downward. By doing so, the casters 7 are also fixed.

In the third embodiment, the function of normally moving the caster 7 and the function of preventing the fall of the adjuster 15 are preserved, and the function of fixing these to the floor when an earthquake occurs is added. It has a feature that it is possible to prevent the problem that the printer 1 with the casters 7 moves significantly when an earthquake occurs and prevents an evacuation route from occurring.
