An inkjet recording apparatus includes: a slider 30 movable back and forth with respect to a fixed base 4 disposed near a home position of an ink cartridge 10; a cap 20 which is attached to the upper part of the slider 30, formed of an elastic member that is opened on its upper end portion 21 so as to cover the head surface 11 of the ink cartridge 10, narrowed at the middle portion 22, and widened toward the lower end portion 23; and a cam mechanism 5 which changes the pressure inside the cap 20 from a positively pressurized status into a negatively pressurized status when the ink cartridge 10 moves within the home position, and at a standby state, maintains the negatively pressurized status so that the cap 20 adsorbs to the head surface 11.
A printer with a cap mechanism. The printer comprises a print head comprising a nozzle, a cap module comprising a cap and a hole, and a positioning module comprising a pin. When the print head moves in a first direction to push the positioning module, the pin escapes from the hole, whereby the cap module moving in a second direction enables the cap to cover the nozzle. When the print head moves in a direction opposite to the first direction, the pin enters the hole enabling the cap module to maintain a predetermined distance from the print head.
