DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fall prevention mechanism for an image processing apparatus, and more particularly, to a fall prevention mechanism for an image processing apparatus which prevents a vertically long image processing apparatus from falling and facilitates maintenance.

[0002]

2. Description of the Related Art For example, conventionally, radiation image information of a subject such as a human body is temporarily recorded on a stimulable phosphor by using a stimulable phosphor (stimulable phosphor), and the radiation image information is stored. Is reproduced on a photographic photosensitive material such as a photographic film, or a CRT or the like is output as a visible image. The stimulable phosphor is composed of radiation (X-ray, α-ray, γ-ray,
(Electron beam, ultraviolet ray, etc.) refers to a phosphor that stores a part of this radiation energy and emits stimulated emission according to the energy accumulated by irradiation of excitation light such as visible light. This stimulable phosphor is usually used as a sheet-like stimulable phosphor sheet because of its easy handling.

In the above-described system, for example, a loading section in which a stimulable phosphor sheet in which radiation image information of a subject is recorded in advance via a cassette or a magazine, and a stimulable phosphor sheet in which radiation image information is recorded are provided. A reading unit that photoelectrically reads the radiation image information by irradiating the excitation light, and an erasing unit that erases the radiation image information remaining on the stimulable phosphor sheet after reading the radiation image information are integrally incorporated, A so-called built-in type radiation image information reading apparatus for circulating or reciprocating the stimulable phosphor sheet in the apparatus has been adopted.

[0004] By the way, as this type of radiation image information reading apparatus has become widespread, it has been made as compact as possible.
That is, there is a strong demand for space saving. For this purpose, it is preferable to reduce the installation area as much as possible. As a result, the radiation image information reading apparatus itself must have a vertically long structure.

In this case, since the center of gravity is located at the upper part due to the vertical structure, it is necessary to avoid that the radiation image information reading apparatus of this type falls due to a large vibration or a careless collision. To this end, a method is conceivable in which the radiation image information reading device is fixed to anchor bolts projecting from the floor surface via screws or the like. However, according to the conventional method of fixing the radiation image information reading apparatus with the anchor bolts as described above, when repairing or performing maintenance for failure, the handling is extremely complicated. That is, since this type of device requires a maintenance from the front, side, back, or top of the device because the internal structure becomes complicated with the downsizing, the device is bolted. There are often local restrictions that maintenance can only be performed from the front or one side by being fixed.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to overcome this kind of inconvenience, and it is possible to reliably prevent the image processing apparatus from overturning and to easily perform maintenance. An object of the present invention is to provide a fall prevention mechanism for an image processing apparatus.

[0007]

In order to achieve the above object, the present invention provides a first member fixed to a floor, and a first member extending in a direction perpendicular to the first member. A space for accommodating the image processing apparatus from the second member, a third member laid on the second member, and a top plate fixed to the second member or the third member; Further, a fourth member for preventing the movement of the image processing device is detachably provided on the first member, and the top plate or the second member is tilted on the top of the image processing device. It is characterized in that a holding member for blocking is attached.

In the above configuration, if the fourth member is removed from the first member, the image processing apparatus can be easily taken out from the overturn prevention mechanism. As a result, the image processing apparatus can be maintained from any direction, and in the event of a failure, the image processing apparatus can be easily moved and repaired. The image processing apparatus for which maintenance or repair has been completed is housed in a space defined by the first member, the second member, the third member, and the top plate, and securely holds the fourth member in the first member. The image processing apparatus itself can be easily fixed by being fastened to the member, and it is also useful for prevention of falling. In this case, when a holding member for holding the top of the image processing apparatus is attached to any of the top plate, the second member, and the third member, the image processing apparatus can be fixed more stably. 1
Described invention).

When the plate is projected from the second member in parallel with the top plate, for example, a keyboard for a personal computer can be stored in a storage space formed between the top plate and the top plate. It is preferable to cooperate with the personal computer body mounted on the apparatus (the invention according to claim 2).

Further, if the second member is provided with a storage means for storing a cassette for an image processing apparatus, an image is recorded,
Alternatively, it is suitable for storage and handling of a cassette containing a stimulable phosphor sheet before recording (the invention according to claim 3).

Therefore, a mechanism for preventing the image information reading device 10 from falling down employs the following configuration. The overturn prevention mechanism 70 is provided with the first overturning mechanism 70 so as to secure an interval slightly larger than the side length of the image information reading apparatus 10.
And a second leg member 72b (first member). Columnar members 74a, 74b (second members) extend vertically upward from one end of each of the leg members 72a, 72b, and the columnar members 74a, 7b.
A top plate 76 is fixed to the upper end of 4b. The area of the top plate 76 is preferably large enough to sufficiently cover the top of the image information reading device 10. On the other hand, the columnar member 74a,
74b, the leg members 72a, 72b and the top plate 76
The first back transverse member 78 and the second back transverse member 80 (third member) are bridged between the columnar members 74a and 74b. A front cross member 82 (fourth member) is detachably bridged to the other ends of the leg members 72a and 72b. More specifically, the front transverse member 82 has a first tongue piece 84a and a second tongue piece 84b at both ends thereof, and is provided on the first and second tongue pieces 84a and 84b. If the screw 85 is screwed into the hole not to be screwed and its tip is screwed to the leg members 72a, 72b, the front horizontal member 82 is engaged with the leg members 72a, 72b. Therefore, the leg members 72a, 72b and the columnar members 74a, 74
The space b for accommodating the image information reading device 10 is defined by b, the rear horizontal members 78 and 80, and the top plate 76.

Can be removed from the overturn prevention mechanism 70. Then, the image information reading device 10 can be easily taken out to the front horizontal member 82 side. For example, the image information reading device 10 which has been repaired or maintained and inspected has a front horizontal member 8.
In a state where 2 is removed, it is accommodated in the space between the top plate 76 of the overturn prevention mechanism 70 and the leg members 72a, 7b. At this time, it is preferable that the back surface of the image information reading device 10 be firmly in contact with the back transverse members 78 and 80. In this case, the image information reading device 10 may be fixed by extending the adjuster bolt 68 toward the floor, but there is no particular problem even if the adjuster bolt 68 is not used. This is because the image information reading device 10 may be arranged in the space by the front horizontal member 82. Then, a screw 85 is inserted into the tongue pieces 84a and 84b of the front horizontal member 82 to secure the tightness between the leg members 72a and 72b and the front horizontal member 82, and the image information reading apparatus 10 is turned over by the overturn prevention mechanism. 7
It is prevented from being led out from 0 or falling down. As described above, the keyboard 96 can be housed between the plate body 94 and the bottom surface of the top plate 76, and various articles such as a display can be mounted on the top surface of the top plate 76 as necessary. Can be placed. Furthermore, a cassette to be used in the image information reading device 10 or a cassette after the image reading has been completed can be temporarily stored in the holding member 98 provided on one of the columnar members 74a and 74b.

[0025]

As described above, according to the present invention, a vertically long image processing apparatus having a relatively high center of gravity can be firmly positioned and fixed. Therefore, even when a large vibration is caused or an unexpected collision occurs and the image processing apparatus is about to fall, the front horizontal member (the fourth member) and the top plate sufficiently prevent the fall. Moreover, since the image processing apparatus can be easily taken out by removing the front horizontal member (fourth member), it is possible to easily repair or maintain the image processing apparatus. Furthermore, according to the present invention, since the overturn prevention mechanism has a relatively simple configuration and the space is not so large, an effect is obtained that the image processing apparatus can be securely fixed even in a narrow place.
