Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a rotary play device for children installed in plazas such as department stores.

[Prior art]

Conventionally, in children's play areas such as department stores and amusement parks, there are play machines where you insert a coin and scoop up your favorite sweets from a casing, or machines where you match identical pictures divided on a drum by rotating the handle. A game machine such as a throttle machine in which players compete for points by playing the game is generally known. In these games, multiple rotating boards with independent rotations are simultaneously rotated in one operation, and each rotating board is stopped at random regardless of the player. If some pictures match by chance, music will be played and prizes will be given out. It was like a release.

Conventional rotary play devices do not have an input means that allows a child to select a picture of their own will or to select a stop position at a certain timing, and the operation is simple and does not have much variety, making it difficult for young children and children. It could not be said to fully satisfy my interests.

[Purpose of invention]

The object of the present invention is to provide a rotary game device in which the start-up at the start of rotation and the low-speed rotation before stopping are unexpected rotational movements.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention includes a ring portion having a picture, figure, etc. drawn on its periphery, a drive mechanism that rotationally drives the ring portion according to an initial condition such as insertion of a coin, a braking mechanism that brakes and stops the annular portion; the braking mechanism includes a disk that is fixed coaxially with the annular portion and has a small diameter recess formed on the outer periphery; a rotatable roller that rotates to engage the roller in the recess, a rotatable metal fitting connected to the rotary plate via a coil spring, and a rotatable metal fitting that is rotated by excitation. It is characterized by being comprised of a solenoid that causes

[Effect]

After inserting the coin, the motor 52 rotates and the drive mechanism 4
Due to the operation of 9, the annular portion 5 rotates with a slight delay in most cases. Next, even when the motor 52 stops rotating, the annular portion 5 continues to rotate due to inertia, and due to the stepwise deceleration action of the braking mechanism 63, the annular portion 5 moves rhythmically and comes to a stop. At this time, one picture on the annular portion 5 stops facing a predetermined reference position.

In the above embodiment, the arrow 6 drawn on the casing 1 was used to specify the stopping angle position of the annular portion 5, but instead of this, the arrow 6 is drawn on the casing 1 to specify the stopping angle position of the annular portion 5. A movable substantially rectangular surrounding plate 6a may be provided. The enclosing plate 6a and the descending/elevating mechanism 83 for the enclosing plate 6a will be explained below with reference to FIG.

Appropriate pictures, figures, etc. (not shown) are drawn on the surface of the surrounding board 6a. The surrounding plate 6a can be lowered and raised by a link mechanism which will be described later. That is, the metal fitting 73 is V-shaped, and one left arm 73a is attached to the pin 70.
and a plunger 76, one end of the other right arm 73b is rotatably supported by the pin 70, and the other end is rotatably connected to a draw rod 77.

Supported for free movement. One end of the rocking plate 80 and the upper end of the retractable rod 77 are rotatably connected by a pin or the like, and a push-up rod 81 integral with the surrounding plate 6a is pivoted to the other end of the rocking plate 80. Thus, the retraction rod 77 and the bracket 7
9. A link mechanism is constituted by the rocking plate 80 and the push-up rod 81, and when the solenoid 75 is not energized by this link mechanism and the spring 78 before inserting a coin into the coin insertion section 12. , the surrounding plate 6a is placed at a position separated from the annular portion 5. Then, when the solenoid 75 is energized and the metal fitting 73 rotates, the retracting rod 77 and the push-up rod 81 move up and down using the pivot point of the bracket 79 as a fulcrum, which lowers the surrounding plate 6a and finally closes the ring. It moves so that it overlaps the picture of a predetermined section drawn on the periphery of the section 5 in order to surround it.

Next, the operation of the present invention configured as described above will be explained.

Before inserting a coin into the coin insertion section 12, the solenoid 75 is off (Figs. 3, 4, and 5), and the roller 72 of the rotary plate 71 is in the raised position due to the link with the metal fitting 73, and the recess of the disc 65 65A, 65B, 6
5C, ... are separated from 65P (phantom line in Fig. 5). Then, when a predetermined coin (game coin or 50 yen coin, etc.) is inserted, the coin detection unit 2
7 sends a start signal to the control section 26. Then, the control unit 26 blinks the lamps 28 to 30,
Music such as "Toriyanse" is played from the speaker 13, and the rotation motor 52 is energized (FIG. 7). Therefore, the annular portion 5 begins to rotate below the surrounding plate 6,
The lamp 21 indicating the first time blinks. At this time,
3-5, rotation of motor 52 rotates output shaft 54 via gearbox 53. In FIGS. The screw 55 rotates idly together with the output shaft 54 until it comes into contact with the engagement screw 57, and after a predetermined time delay, the engagement screw 57
and rotates the input shaft 56. This rotation is transmitted to the cylindrical portion 61 via the sprocket 58, chain 68, and sprocket 66, and is also transmitted to the cylindrical portion 62, disk 65, and rotary encoder 67.
It also rotates. In this way, the annular portion 5 rotates to such an extent that the pictures 5a, 5b, and 5c of the crane, turtle, and rabbit can be distinguished, but because the rotation of the input shaft 56 is delayed, the annular portion 5 rotates against the player's wishes. Start rotating.

While the annular portion 5 is rotating, the lamp 21 above the LED display portion 17 at the center of the display surface 2 blinks to notify that this is the first operation. At this time, press the crane, turtle, and rabbit push buttons 8 on the operation surface 4.
-10 lamps 28-30 are also blinking, and music is being emitted from the speaker 13.

Next, when the player presses one of the pushbutton switches 8 to 10, a stop signal is transmitted to the control section 26 to stop energizing the motor 52, and at the same time, the solenoid 75 is energized. At this time, the annular portion 5 is still rotating due to inertia, and in FIG.
3 rotates counterclockwise to rotate the rotating plate 71 counterclockwise, and the roller 72 descends to the disk 65.
However, since the annular portion 5 is rotating due to inertia, the roller 72 is fitted into one of the recesses 65A to 65P, for example, which is fitted first.
Passing over the concave portions 65A, 65B, 65C, ...65P in sequence, the convex portions 65a, 65b, 65c, ...65p
Climb onto the next recess 65A, 65B, 65C,
...65P, and then the next convex portions 65a, 65
b, 65c, ... 65p. While repeating this oscillation, the coil spring 74 finally
The resilient force overcomes the rotational force due to inertia, and the roller 72 fits into one of the recesses 65A, 65B, 65c, . . . 65P. That is, the annular portion 5 is decelerated in stages and comes to a complete stop.

At this time, the arrow 6 will point to one of the crane, turtle, rabbit, and star pictures 5a, 5b, 5c, and 5d on the annular portion 5. The state in which the rotation of the annular portion 5 is decelerated and stopped is achieved by pressing one of the push button switches 8 to 10 described above, thereby stopping the rotation of the motor 52 and giving the operator a temporary sense of stopping. However, since the annular portion 5 continues to rotate due to inertia, it rotates against the operator's will. In other words, the screw 55 of the output shaft 54 and the input shaft 56
The engagement screw 57 is disengaged and rotates on its own, and the annular portion 5 is gradually decelerated and comes to a complete stop. Therefore, the stop of the annular portion 5 is not as regular as when it is started, so the stop time cannot be predicted, and it is possible to add variety and diversity to the game.

On the other hand, the control section 26 decodes the position of the rotary encoder 67 rotating in synchronization with the rotation of the annular portion 5, calculates a score, and displays it on the LEDs 17-20. Then, score (4 points, 5 points, 6 points and
10 points) is equal to or higher than the winning prize score, the control section 26 sends a rotation signal to the motor 92 (FIGS. 6 and 7), and the ejection disk 88 is intermittently rotated about the mounting shaft 93. Due to this rotation, the notch 89
The prize 93 that falls and is surrounded moves as the ejection disk 88 rotates, and the prize 93 meets the notch 89 of the ejection disk 88 at a position where the notch 89 and the ejection port 86 overlap, that is, at a position directly below the shielding plate 87. Since the discharge ports 86 of the baskets 85 coincide, the prize 93 will be discharged to the prize outlet 14'. Incidentally, since the shielding plate 87 blocks the following prize 93, the prize 93 does not pass through the ejection disk 8.
With the intermittent rotation of 8, prizes are taken out one by one from the prize exit 14'.
will be released. Also, prize 93 after release
operates the actuating piece, and this detection signal is sent from the microswitch to the control section 26 to stop the rotation of the motor 92.

In this way, after the first push button operation is completed, the solenoid 75 is de-energized by the timer built in the control unit 26, and all mechanisms return to their original starting state, and when a coin is inserted, the solenoid 75 is de-energized. The ring portion 5 begins to rotate and the above-described operations are repeated to enter a state where the game can be enjoyed.

[Effect of idea]

As explained above, according to the present invention, it is possible to select a picture in which the annular part starts rotating later than expected and come to a stop position, and then operate the switch. Further, since the annular portion comes to a stop after a gradual and irregular deceleration state, it is possible to provide a game device that has an unexpected movement that is contrary to the player's intention.
