Description

  The present invention relates to a gaming machine such as a pachinko machine.

  In gaming machines such as pachinko machines, a game board is detachably assembled to an inner frame that can be opened and closed with respect to an outer frame, and a front frame is provided on the inner frame so as to be opened and closed. In recent years, in addition to conventional veneer game boards, acrylic game boards that are thinner than veneer game boards may be used in game boards. Acrylic game boards are transparent, and a production device is often used on the back side of the game board, so that a limited space can be expanded as much as possible to create a dynamic production board. Thinly set. The acrylic game board is thinner than the veneer game board because the cost is higher and the weight is higher. Then, in the game hall, when changing the base (changing the model), only the game board is replaced. However, when the inner frame is shared, it is necessary to make the board surface (front surface) of the game board constant because of the launch of the game ball. Therefore, when the game board is attached to the inner frame from the front, the rear face of the game board is used as a reference, so that the front position of the board surface is shifted and cannot be attached to the inner frame, which is versatile. Therefore, there is a need for a pachinko machine using an inner frame that can be used in common even when game boards having different thicknesses are used when the game board is replaced.

As such a gaming machine, for example, an adjustment member for adjusting the thickness dimension of the gaming board is provided on the back surface of the thin gaming board (acrylic) so that the gaming board and the adjusting member are both mounted on the gaming machine frame. By fixing, there exists a thing which makes the board surface (front surface) of a game board constant, and shares a game machine frame (refer patent document 1).
JP 2007-135686 A

  In such a gaming machine, a thin gaming board (acrylic) and an adjustment member are stacked to match the thickness dimension of a conventional gaming board (veneer), the board surface (front face) of the gaming board is made constant, and the inner frame The inner frame can be used in common even if the game boards have different thicknesses. However, in order to adjust the thickness dimension of the game board, an adjustment member is necessary, and the increase in the number of parts is not only costly but also troublesome to install.

  Further, since the adjusting member is provided between the inner frame and the game board, the space in the depth direction with respect to the gaming machine is inevitably narrowed, and the degree of freedom in structural design of the gaming machine is hindered.

  An object of the present invention has been made in view of the above circumstances, and even when the inner frame is shared, it is possible to use game boards having different thicknesses, while ensuring the internal space of the inner frame, The object is to provide a gaming machine to which a board can be easily attached.

In order to solve the above-described problem, a gaming machine according to the present invention described in claim 1
A first gaming board having a first thickness and a second gaming board having a second thickness that is thinner than the first thickness are each provided with an inner frame that is detachable from the front. ,
The inner frame abuts against the back surface of the first game board when the first game board is attached, and projects a predetermined height forward from the rear wall that supports the first game board. A protrusion housed in a space provided in the first game board in order to avoid interference with all or part of itself,
When the second game board is attached to the inner frame, the back surface of the second game board is in contact with the projecting portion and rises from the rear wall to support the second game board,
The front position of the second game board is formed in the same plane as the front position of the first game board.

According to the second aspect of the present invention, the protruding portion has a protruding shape, and is formed by a base protrusion rising from the rear wall, and an engaging protrusion protruding forward inside the front surface of the base protrusion. ,
The second game board is provided with a bottomed or penetrating engagement portion extending in the thickness direction corresponding to the engagement protrusion,
When the first game board is attached to the inner frame, the base protrusion engages with the space portion, and holds the position of the first game board in the board surface direction,
When the second game board is attached to the inner frame, the back surface of the second game board contacts the front surface of the base protrusion, and the engagement protrusion engages with the engagement portion, The position of the game board in the board direction is maintained.

  According to the gaming machine of the first aspect of the present invention, the rear wall of the inner frame is formed with a projecting portion projecting a predetermined height forward from the rear wall, and when the first game board is attached to the inner frame, The protrusion is housed in a space formed in the first game board. When the second game board is attached to the inner frame, the rear surface of the second game board comes into contact with the protruding portion, and the second game board is raised from the rear wall, so that the front position of the second game board is It is formed in the same position as the front surface of the first game board. According to this, when a thin second gaming board is attached by a simple structure in which only a protrusion is provided on the inner frame, the front position (board surface position) of the first gaming board is raised by raising the thickness. Since it can, the inner frame can be shared.

  In addition, since the projecting portion is formed on the inner frame, there is no need for an adjustment member for raising the height, the height relative to the second game board is adjusted, and it becomes possible to attach the game board to the inner frame. The score can be reduced. As a result, the cost can be reduced.

  Further, since the thin second game board is raised and attached by the projecting portion, the game board can be enlarged and the space in the game board unit can be expanded. As a result, the degree of freedom of structural design for the entire gaming machine can be increased.

  According to the gaming machine of the second aspect of the present invention, the projecting portion has a projecting shape that forms a base projection and an engaging projection, and when the first game board is attached to the inner frame, the base projection is a space portion. When the second game board is attached to the inner frame, the back surface of the second game board contacts the front surface of the base protrusion, and the engagement protrusion engages with the engagement portion. According to this, since the protruding portion is formed on the base protrusion and the engaging protrusion, the space portion of each game board, the penetrating or bottomed engaging portion is associated with the base protrusion and the engaging protrusion. Therefore, even when two game boards having different thicknesses are used, not only can the front positions be the same, but they can also be used for positioning in the board direction, so it is necessary to form a separate positioning on the inner frame. Disappear. As a result, an increase in cost can be suppressed.
