Description

  The present invention relates to a slot machine. In particular, the present invention relates to a structure of a slot machine including a variable display device (hereinafter referred to as a reel unit) having a plurality of mechanically driven reels as a variable display unit that variably displays a plurality of symbols.

  In general, in a slot machine, a plurality of reels on which a symbol row having a plurality of types of symbols displayed at predetermined intervals on an outer peripheral surface are arranged in parallel in a rotatable manner. A reel unit that variably displays a plurality of symbols is arranged at the center of the main body of the slot machine. The player can observe the design of each reel through the display window in front of the main body.

  For such a slot machine, while widening the field of view of the entire display unit, it is covered with a reel cover so that the inside of each reel and the end face of the reel are not visible to the player, and the front cover is easy to install the reel cover. There has been invented a slot machine that can cope with a change in the specifications of a housing to which the machine is attached (for example, see Patent Document 1).

  In the slot machine according to Patent Document 1, the display portion on which the design of each reel is displayed is formed by a maskless window without a mask that masks the gap between adjacent reels. A plurality of reel covers made of a strip-shaped member having an arc surface covering the gap between adjacent reels are provided inward in the depth direction on the back side of the maskless window. These reel covers have a width larger than the gap between the reels.

And the tip of the sandwiching piece of the reel cover is chamfered.

JP 11-114130 A

  The reel unit used in the slot machine according to Patent Document 1 has an advantage that a gap between the reels is covered with a reel cover, so that the inside cannot be easily seen by the player. Furthermore, even if the blur is noticeable due to the rotation of the reel, the end surface of each reel is not visible, so the player does not notice that there is a blur. That is, the appearance of the reel inside the display unit is not impaired. In addition, for the player who is playing the game, the center of the field of view is the display unit, but there are fewer factors that hinder the player's gaze on the symbols represented on the display unit (e.g., between reels or rotating reel blur) The player will not feel that visual concentration is hindered.

  In addition, the reel unit according to Patent Document 1 has a protrusion on one of the sandwiching piece of the reel cover and a cover mounting portion located between the reels, and a hole on the other. The cover can be easily attached to and detached from the cover attaching portion by fitting or detaching. Furthermore, since the front end of the sandwiching piece of the cover is chamfered, the resistance when the sandwiching piece of the reel cover sandwiches the cover mounting portion is reduced, and the reel cover can be easily attached.
