DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for attaching a display device such as a CRT to a game board of a pachinko machine.

[0002]

2. Description of the Related Art In recent years, a relatively large display device such as a CRT or a liquid crystal display is attached to the center of a game board in a pachinko machine. There is something that decides whether or not. This display device tends to be larger and larger with the diversification of games, and therefore, it takes more time to mount the display device. In particular, a large display device such as a CRT that protrudes greatly behind the pachinko machine is provided with a pachinko machine and a display device during transportation from the viewpoint of preventing damage during transportation and increasing the number of pachinko machines loaded per truck. In some cases, the pachinko machines are transported separately and installed in a pachinko hall, and then a display device is attached to the game board of the pachinko machine from the back.

In order to simplify the mounting work of this display device, a mounting lever is rotatably mounted on the back side of the game board, and the display device is mounted by sandwiching the mounting frame of the display device with the mounting lever. There is something like that.

[0004]

However, since a large number of components are assembled on the back side of the pachinko machine, there is little empty space around the display device.
Therefore, when the display device is mounted, there is a disadvantage that a space for rotating the mounting lever is narrow, and mounting workability is poor.

The present invention has been made in view of such circumstances, and accordingly, it is an object of the present invention to provide a pachinko machine capable of extremely easily mounting a display device even when an empty space around the display device is narrow. An object of the present invention is to provide a mounting structure of a display device of a machine.

[0006]

In order to achieve the above-mentioned object, according to the first aspect of the present invention, there is provided a mounting structure for a display device of a pachinko machine, wherein the display device is detachably attached to a game board of the pachinko machine from behind. A load receiving member for supporting the load of the display device on the back side of the game board, and engaging and holding the display device supported by the load receiving member detachably from behind. A coupling mechanism is provided, and this engagement mechanism is provided with an engagement hole formed in a member fixed to the back side of the game board, an insertion hole formed in a mounting frame of the display device, and an insertion hole. And an engaging projection inserted from the rear and detachably inserted into and engaged with the engaging hole from the rear.

With this configuration, when the display device is mounted, the display device is received and supported by the load receiving member, and the engaging projection inserted from the rear into the insertion hole of the mounting frame of the display device is fixed to the game board. What is necessary is just to insert and engage in the engaging hole of the member made. In this case, since the load of the display device is received and supported by the load receiving member, the engagement projection only needs to prevent the display device from being pulled backward, and the load applied to the engagement projection is small. Therefore, even with the engagement force between the engagement projection and the engagement hole,
By combining with a load receiving member, a relatively heavy display device can be stably mounted and fixed. Moreover, since the work of inserting and engaging the engaging projection into the engaging hole only requires pushing the engaging projection from the rear of the mounting frame of the display device, even if the empty space around the display device is narrow, the display can be performed. The installation work of the device is extremely simple.

In this case, the engaging projection is formed into a slotted cylindrical shape, and a wedge member is inserted from the rear into the inside thereof so that the engaging projection is mounted when the display device is mounted. The wedge member may be pushed into the engagement protrusion while the child is inserted into the engagement hole, so that the engagement protrusion is pushed out and engaged with the engagement hole. With this configuration, the engagement state between the engagement protrusion and the engagement hole is locked by the wedge member, and a strong engagement force is obtained.

According to a third aspect of the present invention, the load receiving members are provided so as to protrude rearward at two locations corresponding to the left and right sides of the display device, respectively, and are formed on the mounting frames on the left and right sides of the display device, respectively. The display device may be positioned by fitting each load receiving member into the notch. With this configuration, the load receiving member receiving the load of the display device also functions as a positioning member for positioning the display device, and the structure for positioning is simplified.

Further, a guide portion for guiding the attachment / detachment of the display device may be formed at the rear end of the load receiving member. With this configuration, the display device can be smoothly guided to the load receiving member by the guide portion at the time of mounting.
