Claims

[Scope of utility model registration request]

Multiple nozzles are installed around the rotating head,
In an inkjet printer that prints by moving paper in the direction of the rotation axis of the head, an ink holder that holds a plurality of solid inks is installed at the top of the head, and an ink feed solenoid is used to ink the solid ink at the bottom. An ink stopper is provided to prevent ink from falling, and an ink holding section is provided above the ink stopper to temporarily hold the next solid ink, and a shape or position is provided for each ink tank below the ink feed solenoid. A different detent rod and a detent rod hole for inserting the detent rod into the ink tank are provided, and when the detent rod is inserted into the detent rod hole, the ink stopper is driven to release the solid ink at the lowermost part. A safety device for an ink feed mechanism, characterized in that the next solid ink is held in the ink holding section while being fed into an ink tank.
