[0002]

2. Description of the Related Art FIG. 19 is a perspective view of a conventional cathode ray tube device.

In FIG. 1, reference numeral 100 denotes a CRT device, 10 denotes a CRT, 11 denotes a display screen of the CRT, and 12 denotes a neck of the CRT. Reference numeral 4 denotes a deflection yoke which is inserted into the neck 12 of the cathode ray tube 10. Reference numeral 4a denotes a DY spacer, 2 denotes an explosion-proof band attached to the front peripheral portion a of the cathode ray tube 10, and the explosion-proof band 2 is formed in a ring shape having a length slightly smaller than the front peripheral length of the cathode ray tube 10, The explosion-proof band 2 is heated and is fitted to the cathode ray tube 10 by fitting it into the cathode ray tube using expansion caused by heating. Since the CRT 10 is made of glass, the explosion-proof band 2 is most effectively attached by such shrink fitting. Reference numeral 103 denotes a fitting for mounting to a cabinet or the like, which is welded or integrally formed to the explosion-proof band 2.
103a is a flange portion having a hole 103b for screwing.

[0004]

Such a conventional CRT device 100 is mounted on a thick cabinet 2 for mounting.
FIGS. 20 to 22 show the case of attaching to the device 1 and will be described below.

FIG. 20 shows a state in which the CRT device 100 is inserted into the opening 21a opened in the cabinet 21 from the rear surface R of the cabinet 21 and is screwed on the rear surface R of the cabinet 21 with the flange portion 103a of the mounting bracket 103. It is sectional drawing. In the figure, 108 is a screw, 109 is a rear cover, and 122a is a decorative frame. As described above, in the conventional cathode ray tube device, since the position of the mounting flange portion 103a is on the explosion-proof band, the width of the explosion-proof band 2 or the width from the front end of the cathode-ray tube 10 to the formation position of the flange portion 103a is compared. If the width of the cabinet is large, the front surface of the cathode ray tube device is retracted from the front surface of the cabinet, and there is a problem that the visibility is reduced.
In addition, since the rear portion of the cathode ray tube device 100 protrudes greatly on the back side of the cabinet, when there is not enough room on the back side, for example, when using the pachinko machine, a working path is provided on the back side of the pachinko machine. However, since this passage is narrow, there is a problem that such a protrusion on the rear side is obstructive.

FIG. 21 shows a case where the CRT 10 is mounted on the cabinet 2.
1 is a cross-sectional view showing a state in which the front panel 1 is inserted from the front side and is screwed on a front side F of the cabinet by a flange portion 103a. In this case, the decorative frame 122b having a larger size than that shown in FIG. 20 is required to blindly cover the flange portion 103a, so that the area (effective area) of the front surface of the cabinet 21 that can be effectively used is reduced. This is not suitable especially when it is desired to increase the effective area for hitting nails or providing a winning opening or the like as much as a decorative plate of a pachinko machine. An accessory circuit such as a drive circuit board of the CRT 10 or an accessory component or the rear cover 109 is caught by the opening 21a, and
1a cannot be passed through, so these mountings
After inserting the cathode ray tube 10 from the front of the cabinet, it is necessary to carry out the work of mounting on the rear side R of the cabinet, and there is a problem in workability.

It is sectional drawing which shows the state fixed in the intermediate position of a. In the drawing, reference numeral 121b denotes a back metal fitting, and 122c denotes a decorative frame.
In such a case, because of the presence of the flange portion 103a,
An opening 21 having the same size as that shown in FIGS.
In order to accommodate the CRT in a, a CRT having a size smaller than that shown in FIGS. 20 and 21 must be used, which causes a problem that the visibility is reduced.

Further, the mounting position of the flange portion 103a of the conventional cathode ray tube device 100 is
00, that is, it is biased toward the front side from the center of gravity of the CRT device, so that the weight balance when the CRT device is mounted on the cabinet 21 is poor. There is a problem with reliability. Further, an excessive force is applied to the attached cabinet, and the cabinet may be warped. This is particularly problematic when the panel is mounted at a substantially intermediate position on a large-area plate, such as a pachinko board decorative plate. That is, if an excessive force is applied to the decorative plate, the decorative plate may be warped, or the mounting angle of the decorative plate or the pachinko machine may be deviated, and the state of the ball may change.

The CRT device of the present invention has been made in view of such circumstances, and a display screen of the CRT device protrudes from the front surface of the cabinet to ensure good visibility and to the rear side of the cabinet. The present invention provides a CRT device capable of suppressing the amount of protrusion of the CRT, reducing the restrictions on mounting, and effectively using the front surface of the cabinet, a method of mounting the CRT device, and a pachinko machine with the CRT device. It is.

1a is a mounting flange, and 31b is a hole through which a mounting screw or a positioning dowel is inserted. If the mounting member 31 is loose, the auxiliary member 31 d is provided between the mounting members 31.
You only have to attach.

In FIG. 7, 32 is a mounting member, 32b is a hole for a mounting screw or a positioning dowel, and has the same configuration as that of FIG. 6 except that it does not have a flange portion.

In FIG. 8, reference numeral 33 denotes a mounting member having a sleeve structure; 33b, holes for mounting screws and positioning dowels;
Reference numeral 3h denotes a notch formed to facilitate attachment of the DY spacer 4a.

The mounting member 33 is used for attaching to the CRT 10 without using the explosion-proof band 2.
In the same manner as described above, the shape is formed into a ring shape and the length is slightly smaller than the peripheral length of the front surface of the cathode ray tube, and is fastened to the front peripheral portion a of the cathode ray tube 10 by shrink fitting.

The width 1 of the mounting member 33 is formed to be about the position of the center of gravity of the CRT device 1 from the front end of the CRT device 1 in the same manner as described above. Since this width 1 is about 5 times as large as the width l 'of the explosion-proof band 2, heat diffusion is likely to occur and it takes time to shrink fit. This point is the same as the embodiment shown in FIGS. This can be solved by the example.

In FIG. 9, reference numeral 34 denotes a mounting member having a sleeve structure, 34a is a flange portion, 34b is a hole for screwing or positioning dowels, 34e is a shrink fit which prevents heat diffusion during heating.

I do. The width l of the longitudinal portion 36g is the same as that described above, and the width l 'of the fastening portion 36f is formed to be approximately the same as the width of the explosion-proof band 2.

FIG. 12 is a perspective view showing a state in which the rear cover 9 is attached to the CRT device 1, wherein 7 is a dowel for positioning, and 8 is a screw for attaching.

The CRT device 1 is attached to a cabinet or the like with the rear cover 9 attached in this manner.

FIG. 13 is a perspective view showing a state where the CRT device 1 of the present invention is attached to the decorative plate 21 of the pachinko machine 40, and FIG. 14 is a front view of the pachinko machine 40 to which the CRT device 1 of the present invention is attached. is there.

As shown in the figure, the pachinko machine 40 is provided with a metal frame 41 holding a transparent glass plate on the front surface of the decorative plate 1 provided with a large number of nails and winning holes, and on the lower front surface thereof. It has a well-known structure including a ball receiving tray 42, a spare ball receiving tray 43, a hit ball firing dial 44, and the like. An opening 21a of an appropriate size is formed substantially at the center of the decoration plate 21, and a CRT device is formed in the opening 21a. 1 display screen unit 11
Is facing.

The decorative plate 21 is made of a plywood having a width l ″ of about 20 mm in thickness for driving nails, and an opening 21 a for inserting the CRT device 1 into a substantially central portion of the decorative plate 21. The cathode ray tube device 1 is inserted into the opening 21a of the decorative plate 21 from the back and screwed in. The front part of the cathode ray tube device 1 projects approximately 17 mm from the decorative plate 21. In this case, since the width 1 of the mounting member 3 is about 56 mm and the width of the decorative plate 21 is about 20 mm, the amount of protrusion of the cathode ray tube device 1 can be adjusted to about 36 mm by adjusting the mounting position on the back surface. Can be adjusted.

Reference numeral 22 denotes a decorative frame which covers a protruding portion of the front surface of the decorative plate 21 of the cathode ray tube apparatus 1. The decorative frame 22 has a large area (effective area) for nailing the decorative plate 21. It is formed and fitted so as to closely fit the periphery of the front surface. A light emitting element such as an LED for illumination may be incorporated in the decorative frame 22. In this case, the decorative frame 22 is mounted around the cathode ray tube 10 with a margin for a circuit board for light emission.

FIG. 15 is a partial sectional view taken along the line CC of FIG. A back metal fitting 21b for attaching the CRT device 1 is attached to the back surface of the decorative plate 21, and the positioning dowel 7 of the CRT device 1 is inserted into a hole formed in the back metal device 21b, and a screw is attached. 8, both are fixed. Thereby, the CRT device 1 is fixed to the decorative plate 21. By adjusting the size of the rear metal fitting 21b, the amount m of projection of the CRT device 1 from the front surface of the decorative plate 21 can be adjusted.

Further, since the CRT device 1 is attached to the decorative plate 21 at a position substantially at the center of gravity, the CRT device 1 has good stability against vibration and impact and has high reliability at the time of attachment. Further, since no excessive force is applied to the decorative plate 21, it is possible to prevent the decorative plate 21 from warping or the mounting angle of the decorative plate 21 or the pachinko machine 40 from being changed. Therefore, a relatively heavy cathode ray tube device can be attached, and no problem occurs even if a cathode ray tube having a size larger than the 6-inch cathode ray tube employed in the present embodiment is employed.

Further, since the front surface F of the cathode ray tube 10 projects from the decorative plate 21, the length n of the rear surface R of the cathode ray tube device 1 can be kept small, so that the space is limited to the rear space like a pachinko machine. It can be adopted without any problem even for certain types. In the case of the present embodiment, a 6-inch type CRT is used for the CRT device 1. In this case, the protrusion amount n on the back of the pachinko machine 40 can be set to about 150 mm. We were able to attach without any problem. Further, since the projection amount n is small, even if the pachinko machine 40 is transported while the CRT device 1 is attached to the pachinko machine 40, the CRT device 1 does not hit and be damaged.

Further, since the width 1 of the mounting member 3 is increased and the CRT device 1 is fixed on the rear side R of the decoration plate 21, the CRT device is mounted on the back of the decoration plate 21 of the pachinko machine 40. It is only necessary to insert it from the front and fix it to the rear surface with screws or the like, so that the mounting work and the removing work can be made very easy. In the case of replacing with a CRT device, the replacement operation can be greatly simplified.

Further, since the size of the decorative frame 22 can be reduced as compared with the case where the decorative frame 21 is fixed on the front face F, an effective area for hitting a nail or providing a winning opening or the like is increased. In addition, since the front surface of the decorative plate 21 is not damaged by screwing or the like, it is possible to prevent the decorative plate 21 from being cracked or out of order due to the damage.

Further, as compared with the case where the CRT device is fixed in the middle of the opening 21a of the decorative plate 21, such a structure requires extra space for inserting the flange portion 3a for attachment into the opening 21a. For this reason, it is not possible to employ a large cathode ray tube having the full size of the opening 21a, but according to the present embodiment, a cathode ray tube having the full size of the opening 21a can be adopted.
The display screen can be enlarged, and the visibility can be improved.

FIG. 16 is a perspective view of a CRT device 1 ′ having no mounting member 3.

In the drawing, reference numeral 10 denotes a CRT, 11 denotes a display screen of the CRT 10, 12 denotes a neck of the CRT 10, 2 denotes an explosion-proof band, and 4 denotes a deflection yoke.

51 is a wire to be hooked on the hook 50a, 52 is a decorative frame, 53 is a wire fastening bolt, 58 is a mounting screw, and the metal tube 50, the wire 51 and the bolt 53 are used to mount the CRT 10 from the rear side of the CRT 10.
2, the CRT device 1 ′ is fixed to the decorative plate 21. Thus, the CRT device 1 '
Is the cabinet 21 by the decorative frame 52 and the wire 51.
And the amount of projection of the CRT device 1 ′ at the front surface of the decorative plate 21 can be adjusted by changing the length of the decorative frame 52.

With this mounting method, FIG.
The CRT device 1 ′ having no mounting member 3 as shown in (1) can be mounted on the decorative plate 21 of the pachinko machine 40 with good visibility and with a small amount of protrusion on the back surface.
