BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an office machine desk for mounting an office machine such as an impact printer that generates vibration.

[0002]

2. Description of the Related Art Conventionally, a desk of this type has a deck fixed to an upper part of a support, and a cushioning member is placed on the deck in order to mount an office machine such as an impact printer which generates vibration on the deck. I was supposed to put an office machine on it.

[0003]

However, if the cushioning member is interposed between the deck and the office machine, the vibration is not sufficiently absorbed, and the cushioning member is installed on the same desk or another desk connected to the desk. The vibration is transmitted to another deck and the other deck vibrates. In this case, the vibration of another deck caused by the vertical vibration of the office machine is suppressed to a certain extent by being suppressed by the support, etc., but the vibration of another deck caused by the horizontal vibration of the office machine is large. When a visual display device or the like is placed on another deck, there is a problem that the screen vibrates and it becomes very difficult to see characters and figures on the screen, which hinders the use of the device. The present invention has been made to solve the above problem, and an object thereof is to provide a desk for an office machine that absorbs vibration of an office machine placed on a deck.

[0004]

In order to achieve the above object, a structural feature of the invention according to claim 1 is that an office machine desk in which a deck is supported at a predetermined height by a support, The holder is fixed to the upper part of the support, and the end portion of the deck is hung by a suspender hanging from the holder.

Further, the structural feature of the invention according to claim 2 is that, in the desk for an office machine of the invention according to claim 1, at least one of between the suspending tool and the holder or between the suspending tool and the deck is elastic. This is due to the interposition of members.

Further, a structural feature of the invention according to claim 3 is that in the desk for an office machine of the invention according to claim 1, the holder is composed of an elastic member.

[0007]

In the device according to claim 1 configured as described above, when an office machine such as an impact printer that generates vibrations is placed on the deck, the lateral vibration of the office machine causes the vibration. The deck makes a pendulum motion via a hanger. In this case, since the natural frequency of this pendulum motion is different from the natural frequency generated by the office machine, the pendulum motion is damped and its amplitude does not become so large. As described above, the pendulum movement absorbs the lateral vibration of the office machine that greatly affects the vibration of another deck provided on the same desk or the connected desks, and the lateral vibration is absorbed through the holder and the support body. It is not transmitted to the other deck. As a result, even if a visual display device or the like is placed on the other deck, the device will not vibrate, and the visual display device or the like will not be used.

Further, in the inventions according to claims 2 and 3, the elastic member absorbs not only the horizontal vibration but also the vertical vibration of the office machine. Therefore, according to the inventions according to claims 2 and 3, since the vibration of the office machine is further absorbed as compared with the invention according to claim 1, the vibration transmitted to another deck due to the office machine. Can be smaller.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an entire office machine desk according to the embodiment. This desk is provided with a pair of bases 12, 12 connected by a connecting plate 11, and each base 1
A pair of support columns 13 and 13 which are vertically erected above 2 and 12 are integrally connected at their lower ends. Stays 14 and 14 are fixed to intermediate portions of the columns 13 and 13, and a deck 15 is fixed to the stays 14 and 14. Stays 16 and 16 are also provided on the upper ends of the columns 13 and 13.
Is fixed, and a base 17 is fixed on the stays 16, 16. A pair of holders 18, 18 made of a rigid material such as iron and having a long U-shaped cross section are fixed to the upper surface of the left and right ends of the base 17 along the edges of the base 17. The holders 18 and 18 are provided with hanging mechanisms 20, 20, 20, 20 respectively provided at the end portions of the upper surface portions 18a.
The deck 30 is suspended by the four corners.

As shown in detail in FIGS. 2 and 3, these suspending mechanisms 20 are provided with a chain 21 of a predetermined length hanging from the upper surface 18a of the holder 18, and the chain 21 suspends the deck 30. . The hole 18 is formed in the upper surface 18a of the holder 18.
a1 is formed, and a vibration isolating member 22 made of an elastic material such as rubber and formed in a stepped cylindrical shape is fitted into the hole 18a1. A washer 2 formed in an annular shape on the upper surface of the step of the vibration isolator 22
3 is placed, and a pin 24 extending in the diametrical direction and penetrating the uppermost ring of the chain 21 is fixed to the upper surface of the washer 23. On the other hand, a hole 30a is also formed in the deck 30, and a vibration damping member 25 formed in a stepped cylindrical shape with an elastic material such as rubber is also fitted in the hole 30a. An annular washer 26 is provided on the lower surface of the vibration isolator 25, and a pin 27, which extends in the diameter direction and penetrates the lowest ring of the chain 21, is fixed to the lower surface of the washer 26.

In the office machine desk configured as described above, if an office machine that generates vibration such as an impact printer is placed on the deck 30 and the office machine is operated, the vibration of the office machine will be reduced to the deck. 30 is transmitted. Due to the lateral vibration component of the business machine, the deck 30 makes a pendulum motion with the upper end of the chain 21 as a fulcrum, so that the lateral vibration component is not transmitted to the holder 18, the base 17, and the support column 13. Further, since the natural frequency of this pendulum motion and the natural frequency of the lateral vibration of the office machine are different, the pendulum motion of the deck 30 is attenuated and the amplitude of the motion does not increase. On the other hand, the anti-vibration members 22 and 25 absorb not only the horizontal vibration components of the office machine but also the vertical vibration components of the same machine. In this way, the lateral vibration of the office machine causes the pendulum motion by the chain 21 and the vibration isolating members 22 and 25 (particularly pendulum motion).
