  In addition, a guide piece 24 a for smoothly guiding the game ball B from the second straight guide path 24 to the discharge guide path 25 is provided below the second straight guide path 24.

As shown in FIGS. 3 and 4, the game ball B passes through the first corner portion 22 and the second corner portion 23 on the second straight guide path 24, that is, on the downstream side of the second corner portion 23. A detection sensor 27 for detecting the game ball B that collides with the side walls of the corner portions 22 and 23 and whose rolling speed is reduced is provided.
By reducing the rolling speed of the game ball B, the detection sensor 27 can detect the game ball B more reliably.

As shown in FIG. 3 and the like, the inner corner portion 23 a that is the inner peripheral side of the second corner portion 23 is provided with a capturing portion 28 that can capture the filamentous intruder X that enters the guide path 20.
By providing the catching portion 28 in the inner corner portion 23a of the second corner portion 23, it is possible to prevent the game ball B from passing the detection sensor 27 many times illegally. The surface of the inner corner portion 23a has an arc shape so that the game ball B can easily flow down.

  As shown in FIGS. 5 and 6, the capture portion 28 has a sawtooth-shaped cut portion 28 a, and when an illegal act is performed as shown in FIG. 6, the thread-like intruder X is formed in the cut portion 28 a. It has a hooked shape. For example, the illegal game ball attached to the tip of the thread-like intruder X is allowed to pass through the detection sensor 27 by pulling or loosening the intruder X in a state where the illegal game ball is inserted into the start winning opening 19. When an illegal act is performed, the intruder X is caught or cut by the cut portion 28a. As a result, it is possible to prevent an illegal winning action (got action) and to leave a trace of the illegal action (see FIGS. 5 and 6), thereby making it easier to grasp the illegal winning action.

The capturing portion 28 has a wide gap (in the left-right direction in FIG. 6B) on the surface side of the inner corner portion 23a so that the thread-like intruder X can easily enter, and on the back side (in FIG. 6B). As it advances in the upward direction, it has a cut portion 28a that is narrower (thinner) so as to easily capture the thread-like intruder X.
Moreover, since the capture part 28 becomes asymptotically narrow (thinner) from the surface side toward the innermost cut part 28a, the thread-like intruder X is smoothly guided by the cut part 28a, and has a shape that is easy to catch. ing.

  In addition, since the start winning device 13 is a visible transparent member, the game ball B that has entered the start winning port 19 flows down the first straight guide path 21, and the first corner portion 22 and the second corner. By colliding with the inner wall of the part 23, the rolling speed is reduced, and then the state of passing through the detection sensor 27 and flowing down to the second straight guide path 24 can be visually recognized.

Thereafter, the game ball B that has passed through the second straight guide path 24 flows down the discharge guide path 25 toward the discharge port 26.
Thereby, the detection sensor 27 reliably detects the passage of the game ball B, and a predetermined number of game balls B are paid out as a prize (prize ball) without excess or deficiency.

As described above, the start winning device 13 can visually recognize the flow mode of the game ball B, and on the upstream side of the detection sensor 27 that detects the game ball B, the first corner portion 22 and the first corner portion 22 that reduce the flow rate of the game ball B are provided. Since the second corner portion 23 is provided with a catching portion 28 for catching an illegal game ball with a fishing line (invader X) attached to the inner corner portion 23a of the second corner portion 23, the components are integrated. It has been simplified.
Thereby, for example, in order to reliably detect the game ball B by the detection sensor 27, it is necessary to separately provide a configuration for decelerating the flow speed before entering the start winning device 13 and a configuration for capturing the illegal game ball. Disappears.

Although the embodiment of the present invention has been described above, the following modifications and changes can be made to the present embodiment without departing from the spirit of the present invention.
(1) The guide path 20 is provided with a first corner portion 22 and a second corner portion 23 and two corner portions in order to reduce the rolling speed of the game ball B flowing down. One may be used, and if three or more are provided, the rolling speed can be further reduced.
(2) The catching portion 28 may be provided also in the inner corner portion 22a of the first corner portion 22, and by providing a plurality of catching portions 28, an illegal winning action is surely prevented.
(3) The catching portion 28 may have any shape as long as it captures the thread-like intruder X. For example, the catching portion 28 is stacked in a vertical direction, and further shifted to the left and right so that the cut portions 28a do not overlap. Arrangement may be made to reliably prevent illegal prize winning acts.
