IPC: A61M1/00
Filed: 2019-09-20
Abstract: To provide: a container housing device that prevents negative pressure from remaining in the container housing device and enables an opening/closing lid body to be opened easily when the opening/closing lid body is to be opened after negative pressure is generated in the container housing device by suction force of a suction source; a waste liquid reservoir comprising the container housing device; and a waste liquid suction system.SOLUTION: In a state in which an opening/closing operation member 63 takes a closing holding posture, the opening/closing operation member is held in a state of being disposed at a closed position of an opening/closing lid body 62 of a canister 6 and a vent valve 64 is disposed at a flow channel closing position for closing an air inflow passage 61231. When suction force of a suction source 2 is applied in this state, negative pressure is generated in a suction space S1 outside a liner 5 in the canister 6. On the other hand, when the opening/closing operation member 63's posture changes from the closing holding posture to an opening permission posture, the vent valve 64 moves from the flow channel closing position to a flow channel opening position for opening the air inflow passage 61231 in response to the posture change.SELECTED DRAWING: Figure 5

Title: Game machine
Inventor: ICHIHARA TAKUTO
IPC: A63F7/02
Filed: 2019-09-30
Abstract: To provide a game machine which has a function to variably display normal symbols and is capable of enhancing game amusement with respect to the function.SOLUTION: In a game machine, in normal symbol performance, "a specific combination of the same number mode" and "a non-specific combination of the same number mode" can be stop displayed. Although both the "specific combination of the same number mode" and "non-specific combination of the same number mode" are modes (the combination of the same number) in which symbols are the same, a normal symbol winning game is executed only when, of these, "the specific combination of the same number mode" is stop-displayed. That is, when "the non-specific combination of the same number mode" is stop-displayed, no normal symbol winning game is executed though "the combination of the same number" is stop-displayed. Thus, to a player who expects "the combination of the same number" to be stop-displayed, unexpectedness can be given, and game amusement can be enhanced.SELECTED DRAWING: Figure 25

Filed: 2019-11-11
Abstract: To provide a game machine capable of executing a performance without any feeling of incongruity even if internal information is reset.SOLUTION: A Pachinko slot machine executes a performance for suggesting a lottery state by using a performance stage, such as day, evening, and night, in a ball putout state "normal (advantageous section)". Although control is shifted to normal when a ball putout state "second AT" is completed in the Pachinko slot machine, a lottery state is cleared since an advantageous section is also completed when the second AT is completed. Immediately after completion of the second AT, a lottery state is not set, thus preventing execution of a performance for suggesting the lottery state. Therefore, after completion of the second AT, a completion screen of the second AT is maintained until control is shifted to an advantageous section and a lottery state is set. When control is shifted to an advantageous section and a lottery state is set, a performance stage, such as day, evening, and night, is displayed according to the lottery state.SELECTED DRAWING: Figure 386
