Title: Damper device
Inventor: SUZUKI YASUAKI
IPC: F16F9/12
Filed: 2018-05-23
Abstract: To disclose an example of a damper device capable of increasing resistance force generated in the damper device when a load input to the damper device is increased.SOLUTION: A connection mechanism 30 is disposed to make a relative rotation speed of a first movable resistance portion 24 to a fixed resistance portion 22, lower than a predetermined rotation speed by adjusting a connection state of a second movable resistance portion 25 and a shaft portion 26. Thus shear resistance force is generated on a region where the fixed resistance portion 22 and the second movable resistance portion 25 are faced to each other, in addition to a region where the fixed resistance portion 22 and the first movable resistance portion 24 are faced to each other in a state that the second movable resistance portion 25 and the shaft portion 26 are connected. When the relative rotation speed of the first movable resistance portion 24 to the fixed resistance portion 22 is increased, the connection mechanism 30 connects the second movable resistance portion 25 with the shaft portion 26, thus the shear resistance force generated in the damper device is increased, and the relative rotation speed can be the predetermined rotation speed or less.SELECTED DRAWING: Figure 7

Filed: 2018-06-06
Abstract: PROBLEM TO BE SOLVED: To provide a game machine capable of reducing damage caused by a fraudulent act using a "dangling board".SOLUTION: In a Pachinko machine 10, a main control unit 110 counts the number of commands (the number of transmission commands) transmitted from the main control unit 110 to a voice lamp control unit 113 and adds the number of transmission commands to each command. In the voice lamp control unit 113, the number of transmission commands included in the received command is compared with the number of commands (the number of reception commands) received by the main control unit 110 counted at a side of the voice lamp control unit 113 to determine if they are identical. Thus, when the number of transmission commands is not identical to the number of reception commands, transmission of a fraudulent command from the "dangling board" can be detected.SELECTED DRAWING: Figure 29
