[Prior art]
A pachinko gaming machine, which is a type of ball-and-ball game machine, is provided with a display device (display means) for displaying and changing a plurality of special symbols related to the game. The game state shifts to the big hit state according to the stop mode of the plurality of special symbols when stopped.
[0003]
That is, when the special symbols are changed, the gaming machine sequentially stops, for example, three special symbols in the reach effect, and the three special symbols are finally stopped in a predetermined stop mode (generally, all three special symbols are mutually stopped). When the same symbol is stopped), it is displayed that the gaming state shifts to the big hit state.
[0004]
The reach effect refers to an effect that is executed when the game state is the reach state, and the reach state is a condition that the already stopped special symbol satisfies the condition of being in the jackpot state, and the remaining one to be finally stopped. Or, it refers to a state in which a big hit state may be displayed depending on a stop mode of a plurality of special symbols.
[0005]
Here, in some gaming machines, a speaker is installed in a normal gaming state, particularly in a reach effect, in order to enhance the interest of the player by voice. The sound from the speaker of the gaming machine is set to have a relatively large volume so that the sound reaches the player's ear without being drowned by the noise emitted from the many gaming machines in the gaming state.

Also, in the hall, which is a game hall, speakers are installed to provide various guidance to the player, and the sound from the speakers here is relatively loud so that the sound reaches the player's ears without fail. Is set to
[0007]
Vibration of a speaker installed in such a game machine or a speaker installed in a hall causes a small vibration of the glass plate via the glass plate holding frame, and a so-called chattering sound is generated between the glass plate and the frame.
[0008]
Here, for example, Japanese Patent No. 2556662 discloses a glass frame for a pachinko game machine in which a front cover is made of synthetic resin, and a metal plate is formed on a glass plate holding frame made of synthetic resin instead of metal. ing. It is stated that such a configuration can prevent illegal acts such as making a hole from the front surface with a baked wire while reducing costs due to resinification.
