Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a monitor device provided with image display means such as a cathode ray tube.

[0002]

2. Description of the Related Art Conventionally, there has been proposed a monitor device provided with an image display means such as a cathode ray tube and configured to display a predetermined image.

This monitor device has an outer casing composed of a chassis for supporting the cathode ray tube and a cover member for covering the cathode ray tube and the chassis. In addition to the cathode ray tube, an electronic circuit portion for supplying a video signal to the cathode ray tube is housed in the outer casing. In this monitor device, an image corresponding to the image signal is displayed on the display surface of the cathode ray tube by supplying a power source and an image signal to the electronic circuit section. The display surface of this cathode ray tube is exposed to the outside through an opening provided in the outer casing.

By the way, this monitor device may be used by being hung from a ceiling in a room through a supporting stay member. In particular, a medical monitor device for displaying an image of an endoscope or the like is often hung from the ceiling and used.

When the monitor device is suspended from the ceiling, first, the monitor device chassis is welded or joined using a number of mounting screws.
Attach the lower end of the stay member. The monitor device is suspended from the ceiling by attaching the upper end side of the stay member to a support member fixed to the ceiling.

[0006]

By the way, in the case where the monitor device is suspended from the ceiling as described above, the above-mentioned monitor device including the above-mentioned cathode ray tube and the like is sufficiently supported so as to support the mass thereof. It is necessary to make the joint between the chassis and the stay member strong.

Therefore, the work of joining the chassis and the stay member is complicated. Further, in order to strengthen the joint between the chassis and the stay member, it is necessary to increase the area occupied by the stay member for mounting the stay member on the outer surface portion of the chassis. Cannot be realized.

Further, in this monitor device, since the chassis and the stay member cannot be easily attached and detached, the stay member once attached to the chassis remains as it is when it is attached. , Used for a long time. That is, it is difficult to movably attach the monitor device to the stay member. Therefore, when the direction of the display surface of the cathode ray tube is displaced, it is difficult to displace the mounting angle of the monitor device with respect to the stay member. Therefore, it is necessary to provide the stay member with a movable portion. Therefore, the structure of the stay member becomes complicated.

Therefore, the present invention has been proposed in view of the above circumstances, and it is easy to attach and detach a stay member used when it is hung from the ceiling, and the stay member is movable. It is an object of the present invention to provide a monitor device that can be attached and that enables the stay member to be downsized and simplified.

[0010]

In order to solve the above-mentioned problems and achieve the above-mentioned object, a monitor device according to the present invention has a chassis for supporting image display means and a nut mounting hole provided in the chassis. And a press nut into which a bolt for inserting the support stay member to the chassis and attaching the supporting stay member to the chassis is screwed.

[0011]

In the monitor device according to the present invention, the press nut into which the bolt for mounting the supporting stay member is screwed is driven into the nut mounting hole provided in the chassis supporting the image display means. Since it is attached to the chassis, it is firmly attached to the chassis even though it is attached by an easy process.
