The explanation of preferred embodiment
The preferred embodiments of the present invention are described below with reference to accompanying drawings.
Figure 1A and 1B and Fig. 2 A to 2D have represented the print cartridge outward appearance according to first embodiment of the invention.Fig. 3 and Fig. 4 are the perspective view of expression print cartridge assembling.Print cartridge 1 main by a box-like rectangular container casing 2 elongated, that have an open surfaces and the cap member 3 that is used for sealing this open surfaces form.Front (among this embodiment, on the basal surface of container casing 2 longitudinal direction upper offset position container casings 2) in print cartridge 1 direction of insertion is formed with an ink supply port 4.When inserting or extract print cartridge 1 out, be formed with locking member 5 and 6 on respectively as the container casing 2 in the relative wall top of front side and rear side.
Near the formed locking member 5 of ink supply port that is positioned at has a rotating fulcrum and the opened top that can outwards open at the fore-end (being positioned in this embodiment, the part of a little higher than print cartridge lower end) of direction of insertion.Formed another relative locking member 6 cooperates with locking member 5 to assist the fixing of print cartridge.
In this locking member 5 and 6 each all has one corresponding to the width that inserts mouthful width on the balladeur train, like this side surface of each locking member 5,6 just as leader with position at width qualification print cartridge.
In addition, below near the locking member 5 that is positioned at the ink supply port, be provided with a storage device 7.Storage device 7 has electrode 7a on the exposed surface of a plate, it is arranged in up and down two row, and the semiconductor memory element is installed on the back side of plate and with electrode 7a and links to each other simultaneously.On the other hand, below another locking member 6, be formed with valve storage chamber 8.
Near ink supply port 4, the middle section of container is formed with a slot part 9, slot part 9 extends at the front opening of print cartridge and along print cartridge insertion/extraction direction at least like this.Slot part 9 has such length and width, that is, front end at ink supply port 4 is arrived regulate print cartridge before the ink supply pin of balladeur train to make the open surfaces of ink supply port 4 perpendicular to the ink supply pin.
On the other hand, the balladeur train 100 that print cartridge is installed on it has a record head 101 in its bottom, and an ink supply pin that is communicated with record head 101 (a plurality of ink supply pin) 102, as shown in Figure 5.One print cartridge presses part (being a slice spring 103 among this embodiment) and is positioned at a zone that is separated with ink supply pin 102 zones of living in, and the while is formed with a location projection 104 and extends along print cartridge insertion/extraction direction between ink supply pin 102 and sheet spring 103.And electrode 106 is positioned on the sidewall 105 of ink supply pin 102 sides, and a groove 107 is positioned at the top of sidewall 105 to engage with a projection 5a of locking member 5.
By adopting said structure, as shown in Figure 6A, if when print cartridge 1 inserts balladeur train and ink supply port 4 is positioned at rear side and print cartridge 1 is pressed on the sheet spring 103, slot part 9 just is subjected to the restriction of projection 104.Therefore, although try hard to a rotatory force be imposed on print cartridge 1 (direction of Fig. 6 A arrow A) so that move under ink supply port 4 one side direction by the sheet spring 103 that is arranged in offset position, the position of print cartridge is limited at the insertion/extraction direction (being vertical direction among this embodiment) that is arranged essentially parallel to regulation.
When being placed on finger on the container casing 2 end face 2b and further print cartridge 1 being pressed to sheet spring 103 with one, print cartridge 1 produces a component with print cartridge 1 surface pressure that will have storage device 7 electrode 106 to balladeur train 100, because the end face 2b of container casing 2 forms a slope with θ angle, wherein the rear side of print cartridge 1 (being locking member 5 one sides) is higher.Therefore, when the electrode 7a of storage device 7 closely contacted with electrode 106, print cartridge was with regard to pressurized and insert ink supply pin 102.In this pressure insertion process, shown in Fig. 6 B, the whole elastic force of the projection 5a of locking member 5 opposing locking member 5 is absorbed in groove 107 then, and projection 5a just engages with groove 107 like this.Therefore, a tangible click passes to finger, makes the user feel that print cartridge has been fixedly mounted on the balladeur train 100.
Although locking member 6 also can have a projection similar with the projection 5a of locking member 5, only the projection 5a that is provided with on the locking member 5 of storage device 7 one sides can prevent the print cartridge setup error.This be because, if there is not the locking member 6 of storage device 7 one sides to produce a click, the user can conclude mistakenly that print cartridge has correctly been installed, although the locking member 5 of storage device 7 one sides also is not positioned at correct position, that is, locking member 5 is positioned at the position that does not also produce click.
Under the state that print cartridge is installed, because the position of print cartridge 1 on insertion/extraction direction is subjected to the restriction of the projection 5a of locking member 5, and print cartridge 1 surface with storage device 7 is subjected to the motive force of sheet spring 103 power of arrow A direction (among Fig. 6 A towards) to be pressed towards the electrode 106 of balladeur train 100, so produce what vibration during no matter printing, contacting all between print cartridge 1 and the balladeur train 100 kept securely.
On the other hand, when will remove print cartridge 1 with replacing or for similar purpose in balladeur train 100 time, locking member 5 is flexibly pressed to container casing 2, locking member 5 just rotates around a little higher than lower end and as the part of rotating fulcrum like this.As a result, the projection 5a of locking member 5 discharges in groove 107.When print cartridge 1 was extracted out under this state, print cartridge 1 was parallel to ink supply pin 102 and moves under the influence of the motive force of leaning on sheet spring 103 under the guiding of projection (guiding element) 104.Therefore, print cartridge 1 can move down from balladeur train 100 under the situation that is used for ink supply pin 102 without any bending force or similar masterpiece.
