Abstract: A drive transmission mechanism includes an electromagnetic clutch and a drive output gear. The electromagnetic clutch includes a clutch shaft, a clutch input gear, a clutch idler gear, and a clutch output gear. The drive transmission mechanism transmits driving power using a first drive transmission path or a second drive transmission path. The first drive transmission path includes the clutch idler gear, a first idler gear, and a first output gear unit to transmit driving power to a rotated member connected to a first output gear unit irrespective of the energizing or the non-energizing an electromagnetic clutch. The second drive transmission path includes the clutch output gear, a second idler gear, and a second output gear unit to transmit driving power to a rotated member connected to the second output gear unit only when the electromagnetic clutch is energized.

Abstract: A liquid supply unit includes a first chamber, a second chamber, an opening/closing member, a biasing member, a pressing member and a flexible film member. The first chamber communicates with a liquid storage container, and the second chamber communicates with a liquid injection head. The opening/closing member changes a posture between a closing posture for closing a communication opening and an opening posture for opening it. The biasing member biases the opening/closing member in a direction toward the closing posture. The pressing member presses the opening/closing member in a direction toward the opening posture. The flexible film member is displaced based on a negative pressure generated in the second chamber. When a pressure receiving portion of the pressing member receives the displacement force from the flexible film member, the pressing member rotates about a pivot point and presses the opening/closing member against a biasing force of the biasing member.

Abstract: A liquid supply unit includes a first chamber, a second chamber, a wall portion, an opening/closing member, a flexible film member and a transmitting member. The wall portion includes a communication opening allowing communication between the first chamber and the second chamber. The opening/closing member changes a posture between a closing posture for closing the communication opening from the second chamber side and an opening posture. The flexible film member is displaced based on a pressure change of the second chamber. The transmitting member transmits a displacement force to the opening/closing member to be the opening posture when the second chamber is set to a negative pressure exceeding a predetermined threshold value, and transmits the displacement force to the opening/closing member to be the closing posture according to a displacement of the flexible film member when the second chamber is pressurized.
