Claim 8

An ink-jet printer as defined in claim 5 wherein said vessel includes a first reservoir containing an ink to be supplied to said recording head and a second reservoir containing the waste ink sucked from said recording head under the action of negative pressure, said reservoirs being connected to each other through said connection.

Claim 9

An ink-jet printer comprising capping means for sealingly closing the ink discharging tip of a recording head, a lever for moving said capping means between a first position in which said recording head is sealingly closed by said capping means and a second position in which said recording head is opened, and means for engaging said lever to inhibit it from moving when said lever is moved to a predetermined position in a predetermined direction and for releasing said lever when said lever is further moved in said predetermined direction.

Claim 10

An ink-jet printer comprising capping means for sealingly closing the ink discharging tip of a recording head, a lever for moving said capping means between a first position in which said recording head is sealingly closed by said capping means and a second position in which said recording head is opened, and means for engaging said lever to inhibit it from moving when said lever is moved to a predetermined position in a predetermined direction and for releasing said lever when said lever is further moved in said predetermined direction.

Claim 11

An ink-jet printer as defined in claim 7 further comprising means for sucking the tip of said recording head through said capping means, said sucking means being adapted to actuate when said lever is further moved from said predetermined position in said predetermined direction.

Claim 12

An ink-jet type printer comprising capping means for sealingly closing the ink discharging tip of a recording head, a vessel receiving chamber for detachably receiving a vessel in which an ink is contained, and means for detecting whether or not the vessel is received in said vessel receiving chamber and for inhibiting the release of said capping means from its closing position when it is detected that the vessel is not set within said vessel receiving chamber.

Claim 13

An ink-jet type printer comprising capping means for sealingly closing the ink discharging tip of a recording head, a vessel receiving chamber for detachably receiving a vessel in which an ink is contained, and means for detecting whether or not the vessel is received in said vessel receiving chamber and for inhibiting the release of said capping means from its closing position when it is detected that the vessel is not set within said vessel receiving chamber.

Claim 14

An ink-jet printer comprising capping means for sealingly closing the ink discharging tip of a recording head, means for sucking the tip of the recording head through said capping means, a first reservoir means containing an ink to be supplied to the recording head, a second reservoir means containing the waste ink sucked from the recording head under the action of said sucking means, a chamber receiving said first and second reservoir means, and means for detecting whether or not both said first and second reservoir means are received by said chamber and for inhibiting the release of said capping means from its closing position when it is detected that both said first and said reservoir means are not set within said chamber.

Claim 15

An ink-jet printer comprising capping means for sealingly closing the ink discharging tip of a recording head, means for sucking the tip of the recording head through said capping means, a first reservoir means containing an ink to be supplied to the recording head, a second reservoir means containing the waste ink sucked from the recording head under the action of said sucking means, a chamber receiving said first and second reservoir means, and means for detecting whether or not both said first and second reservoir means are received by said chamber and for inhibiting the release of said capping means from its closing position when it is detected that both said first and said reservoir means are not set within said chamber.

Claim 16

An ink-jet printer comprising capping means for sealingly closing the ink discharging tip of a recording head, means for sucking the ink discharging tip of said recording head through said capping means, a first ink reservoir means containing an ink to be supplied to the recording head, a second ink reservoir means for collecting the waste ink sucked from the recording head under the action of said sucking means, a chamber for receiving said first and second reservoir means, and means for detecting whether or not both said first and second reservoir means are received by said chamber and for inhibiting the actuation of said sucking means when it is detected that both said first and second reservoir means are not set within said chamber.

Claim 17

An ink-jet printer comprising capping means for sealingly closing the ink discharging tip of a recording head, means for sucking the ink discharging tip of said recording head through said capping means, a first ink reservoir means containing an ink to be supplied to the recording head, a second ink reservoir means for collecting the waste ink sucked from the recording head under the action of said sucking means, a chamber for receiving said first and second reservoir means, and means for detecting whether or not both said first and second reservoir means are received by said chamber and for inhibiting the actuation of said sucking means when it is detected that both said first and second reservoir means are not set within said chamber.

Claim 18

A function restoration suction device comprising means for drawing an ink from the tip of a recording head, a vessel for collecting the waste ink drawn by said drawing means, a vessel receiving chamber for detachably receiving said vessel, and means for permitting said vessel to collect the drawn waste ink when said vessel is mounted in said chamber and for inhibiting said vessel from collecting the waste ink when said vessel is not mounted in said chamber.

Claim 19

A function restoration suction device comprising means for drawing an ink from the tip of a recording head, a vessel for collecting the waste ink drawn by said drawing means, a vessel receiving chamber for detachably receiving said vessel, and means for permitting said vessel to collect the drawn waste ink when said vessel is mounted in said chamber and for inhibiting said vessel from collecting the waste ink when said vessel is not mounted in said chamber.

Claim 20
