When sliding component 132 moves to rear side by the elastic force that is pressed opposing first helical spring 137 and second helical spring 154, first claw component 159 moves to end along initiating terminal in first groove 141, and further moves to end (the position C shown in Figure 18) from the initiating terminal of second groove 142.First claw component 159 that is arranged on position A does not move to the 9th groove 149 from position A, because have step 150 between first groove 141 and the 9th groove 149.

When first claw component 159 arrived the end (position C) of second groove 142, breech lock claw component 133 moved to end (position D) with first claw component 159 from initiating terminal by the elastic force of triple helical spring 161.When being applied to pressure on the sliding component 132 being disengaged under this state, sliding component 132 is moved along the direction of separating with side surface 124b by the elastic force of first helical spring 137 and second helical spring 154.At this moment, first claw component 159 moves to the end (position E) of the 4th groove 144 from position D.When first claw component 159 arrived the end (position E) of the 4th groove 144, breech lock claw component 133 moved to end (position F) from initiating terminal with first claw component 159 by the elastic force of triple helical spring 161 in the 5th groove 145.

When sliding component 132 moved to rear side by the elastic force that is pressed opposing first helical spring 137 and second helical spring 154, first claw component 159 moved to the end (position G) of the 6th groove 146 from position F.When first claw component 159 arrived the end (position F) of the 6th groove 146, breech lock claw component 133 moved to end (position H) from initiating terminal with first claw component 159 by the elastic force of triple helical spring 161 in the 7th groove 147.

As first claw component, 159 in-position H, and when having removed the pressure that is applied on the sliding component 132, sliding component 132 is moved along the direction of separating with side surface 124b by the elastic force of first helical spring 137 and second helical spring 154.That is, first claw component 159 moves and turns back to the initiating terminal (position A) of first groove 141 along the 8th groove 148 and the 9th groove 149.

Therefore, when sliding component 132 was operated and is pressed towards side surface 124b twice, first claw component 159 was advanced around latch locking groove 136a, and turns back to position A.That is, first claw component 159 by the first time press operation be directed to position F from position A, and by the second time press operation be directed to position A from position F.

The 3rd supporting member 157 is formed in the distal end of second supporting member 156 and partly extends, and the 3rd supporting member 157 has second claw component 162 that has columnar shape, as the outstanding mating component of lower surface that is formed in the distal end part.Second claw component 162 is designed to be mounted in the groove 163 in the ink shell 120 that is formed on above-mentioned print cartridge 118.In this embodiment, guide the groove 163 of second claw component 162 to be formed the componental movement path that is matched with latch locking groove 136a wherein with distance pro rata greater than envelope first claw component 159 from position H to position I from the shaft portion 158 of breech lock claw component 133.

That is, when print cartridge 118 is applied in and is pressed towards sliding component 132 so that print cartridge 118 is installed to cassette holder 113, first claw component 159 moves and moves to the position B in second groove 142 in first groove 141.Second claw component 162 moves with first claw component 159, and along mobile in the opposite direction with arrow Y side, and facing to first guiding groove 166 that is formed on the groove 163 in the ink shell 120.Therefore, when first claw component 159 in second groove 142 when position B moves to position C, second claw component 162 is directed into the position K in first guiding groove 166, as shown in figure 21.The position of sliding component 132 should be called as the installation site (second sliding position) as the second place.

When first claw component 159 when the position C of second groove 142 moves to the position D of three-flute 143, second claw component 162 is directed to the position L second guiding groove 167 from position K, as shown in figure 21.When first claw component 159 when position D moves to the position E of the 4th groove 144, second claw component 162 is directed to the position M second groove 142 from position L, as shown in figure 21.When first claw component 159 when position E moves to the position F of the 5th groove 145, second claw component 162 is directed to the position N second guiding groove 167 from position M, as shown in figure 21.

At this moment, print cartridge 118 is in it and is installed to state on the cassette holder 113.If print cartridge 118 is by withdrawing under this state, then print cartridge 118 can not be pulled down from cassette holder 113, because first claw component 159 cooperates with the side surface of the 5th groove 145 and second claw component 162 cooperates with lock part 164.

When exerting pressure by 118 pairs of sliding components 132 of print cartridge subsequently, first claw component 159 sequentially moves to position F, position G, position H, position I and position A as mentioned above.At this moment, second claw component 162 sequentially is directed to position N, position O and position P, and is directed into the position Q of the 3rd guiding groove 168, as described in Figure 21.As a result, second claw component 162 164 is pulled down from the lock part, and is extracted from the groove 163 that is formed on ink shell 120.Therefore, print cartridge 118 can be pulled down from cassette holder 113.

Then, for the printer 111 of being constructed as mentioned above, with the operation of explanation when mounting and dismounting print cartridge 118.

Under print cartridge 118 was not installed in state in the container cavity 124 of printer 111, sliding component 132 was positioned to extract and allows on the position, as Figure 19 and shown in Figure 20.Under this state, the user slides into new print cartridge 118 in the container cavity 124 of cassette holder 113 along Y direction, and thus, the side surface 118b of print cartridge 118 is against sliding component 132.At this moment, second claw component 162 is not positioned on the upper surface 120a of print cartridge 118, and is in the state that can not cooperate with the lock part 164 of print cartridge 118.

When the user further presses print cartridge 118 along arrow Y direction, the bias force of sliding component 132 opposing first helical springs 137 and second helical spring 154 moves along arrow Y direction.Then, first claw component 159 of breech lock claw component 133 moves along first groove 141 and second groove 142 of latch locking groove 136a, and second claw component 162 is directed to position K from the position J of groove 163.First claw component 159 is positioned in the end of second groove 142, position C.When first claw component 159 when first groove 141 and second groove 142 move, ink feed pin 126 penetrates the pin through hole 134a that is arranged in the housing parts 134, discharges among the port 121a with the ink that is inserted into print cartridge 118.Air inlet tube 127 is prevented from crooked state with it and is supported in the barrel portion 135 of sliding component 132, thereby is connected to the intercommunicating pore of print cartridge 118.Precision when therefore, the intercommunicating pore of print cartridge 118 is connected with air inlet tube 127 can be enhanced.

When first claw component 159 is positioned in position C, breech lock claw component 133 bias force by triple helical spring 161 with shaft portion 158 as pivot along direction of arrow rotation around the Z axle, and first claw component 159 moves along the three-flute 143 of latch locking groove 136a.As a result, first claw component 159 is positioned in the end of three-flute 143, i.e. position D.First claw component 159 is directed to position L with second claw component 162.
