As shown in Figure 8, when described door 76 changed to open position, described sweep 97 of pulling out member 77 rotated counterclockwise around rotating shaft part 94.Here, the rotation of sweep 97 makes its outer wall surface 110 change into approximate horizontal state (referring to Fig. 8) from approximate vertical upright state (referring to Fig. 6).The length setting of pulling out the extension 96 of member 77 is a given size, thereby when sweep 97 had rotated, the placed side 98 that its outer wall surface 110 is arranged on housing 75 is the top slightly, and extends along fore-and-aft direction (left and right directions in Fig. 8).Be shown in an open position when middle at described door 76, this outer wall surface 110 is as guide surface, is used for print cartridge 63 is directed on the described placed side 98 of accommodating chamber 78 inside.In other words, describedly pull out member 77 and print cartridge 63 also is used for print cartridge 63 is inserted into described guiding elements of accommodating the chamber 78 from described accommodating the member that chamber 78 pulls out except being used for.
In the present embodiment, each door main body 89 is provided with two and pulls out member 77.That is to say that as shown in figure 10, these are pulled out member 77 and arrange relative to one another along the width of door main body 89.Arrange that so a pair of member 77 of pulling out allows that print cartridge 63 to be supported between them along width pulling out member 77.In addition, in the present embodiment, make these pull out spacing (width size) d1 (referring to Fig. 9) between the member 77 less than the width size d2 (referring to Figure 14) of print cartridge 63.The effect that limits size d1 and d2 like this will be discussed after a while.
As Fig. 6, Fig. 8, Fig. 9 and shown in Figure 10, promote retaining member 90 and be installed on the inner surface of door main body 89.On two sides that promote retaining member 90, be provided with protuberance 146, and in door main body 89, be provided with protuberance holding portion 147.Described protuberance 146 is arranged to from the side that promotes retaining member 90 outstanding.Described protuberance holding portion 147 by along the fore-and-aft direction of door main body 89 (with print cartridge be installed to accommodate in the chamber 78 or from accommodating the direction that chamber 78 is removed) groove that extends constitutes.Described protuberance 146 is coupled in the described protuberance holding portion 147 slidably, is supported along the mode that fore-and-aft direction moves with respect to door main body 89 according to allowing to promote retaining member 90 thereby promote retaining member 90.In other words, promoting retaining member 90 can be in its extrusion position (referring to Fig. 8) and its change between 89 retracted positions (referring to Fig. 6) of withdrawing from extrusion position towards door main body from the inner surface rise of door main body 89.As shown in figure 10, promoting between retaining member 90 and the door main body 89 helical spring 99 to be set.Therefore, promote retaining member 90 and be subjected to the elasticity loading at any time, thereby have the trend that is in described extrusion position, as shown in Figure 8.
As shown in Figure 6, when door 76 is taked the closed position, promote the front surface (the left hand surface among Fig. 6) of retaining member 90 contact print cartridges 63, and by being promoted to move to described retracted position relatively by print cartridge 63.Therefore, print cartridge 63 is pushed rearward by the elastic force that promotion retaining member 90 is subjected to described helical spring 99, thereby print cartridge 63 is remained under the state of locating with respect to housing 75.Therefore, prevent that reliably ink from leaking from the ink supply valve 115 of print cartridge 63.
In the present embodiment, promote retaining member 90 and form writing board shape.The wall surface 84 of this promotion retaining member 90 (in door 76 is in the closed position time the and the surface faced of the front surface of print cartridge 63) forms the plane, and is formed with a pair of projection 141 and 142 on this wall surface 84, as Fig. 5 and shown in Figure 10.Therefore, in the time of in door 76 is in the closed position, these projections 141 contact and are pressed against on the front surface of print cartridge 63 with 142.These projections 141 and 142 are arranged with prescribed distance along the width of door 76.Therefore, in the time of in door 76 is in the closed position, described projection 141 contacts the both sides of the coupling part 143 of print cartridge 63 with 142, do not contact but retaining member 90 is not pushed into coupling part 143.
As shown in figure 10, between lock construction element 91 and door main body 89, get involved helical spring 100.Therefore, this lock construction element 91 is subjected to loading from the elasticity that door main body 89 makes progress at any time.In addition, the end face 103 of the key part 133 of lock construction element 91 constitutes downward-sloping inclined surface.Therefore, as Fig. 8 and shown in Figure 6, at door 76 when open position is changed into the closed position, the apical margin part 130 (referring to Fig. 8) of the opening 88 of the described end face 103 contact housings 75 of lock construction element 91, and when door 76 rotated towards the closed position, lock construction element 91 was pushed relatively and inwardly is withdrawn in the door main body 89 by described apical margin part 130.In case door 76 has changed to the closed position with the position fully, then lock construction element 91 stretches out from door main body 89 once more, and described key part 133 engages (referring to Fig. 6) with housing 75.Specifically, the key part 133 of lock construction element 91 is coupled to (referring to Fig. 5 and Figure 11) in the lock construction element mating holes 83 that is arranged in the housing 75.At any time the elasticity loading that is subjected to described helical spring 100 owing to lock construction element 91 has the trend of stretching out from door main body 89, thereby in the closed position, so door 76 is maintained in the described position.
As Fig. 9 and shown in Figure 10, trip lever 92 forms rectangular plate shape, and is installed on the top of outer surface 105 of door main body 89.Office, bottom at trip lever 92 is provided with supporting pin 106.In addition, door main body 89 is provided with pin supported hole 107.Described supporting pin 106 is coupled in this pin supported hole 107, and trip lever 92 can rotate around supporting pin 106 thus.Specifically, trip lever 92 can be as shown in Figure 6 by standing and the rotation change position between the position of about 45 ° of (degree) (referring to Figure 11) and the position (referring to Figure 12) that trip lever 92 approximate horizontal keep flat that tilts, the position of outer surface 105 almost parallels of door main body 89, trip lever 92.When outer surface 105 almost parallels of trip lever 92 and door main body 89, the position of trip lever 92 is defined as " standing place ", trip lever 92 is defined as " neutral position " in the position that tilts about 45 ° the time, and the position of trip lever 92 when its approximate horizontal keeps flat is defined as " keeping flat the position ".On the end face 151 of trip lever 92, be marked with or be carved with arrow.This makes that the direction of operating of trip lever 92 is clear.
The bottom end surface 108 of trip lever 92 forms the regulation shape.This bottom end surface 108 constitutes cam, and it makes lock construction element 91 vertically slide when changing in the position of trip lever 92.The shape of described bottom end surface 108 is not particularly limited, and can be Any shape, as long as it makes when trip lever 92 rotates that described lock construction element 91 is as described below and equally slides.
Figure 11 is the cutaway view of refill unit 10, and the mode of operation of trip lever 92 is shown.Figure 12 is the enlarged drawing of the major part of Figure 11.
As mentioned above, the bottom end surface 108 of trip lever 92 constitutes cam.In the time of in the lock construction element mating holes 83 that lock construction element 91 is coupled to housing 75, in the time of promptly in door 76 is in the closed position with respect to housing 75, trip lever 92 can carry out moving (referring to Fig. 9 and Figure 10) with the rotation that described supporting pin 106 is the center in the zone between described standing place and neutral position.In the present embodiment, the position of centre of gravity of trip lever 92 is set for feasible: trip lever 92 will always have the trend to the neutral position motion under its deadweight effect, i.e. trend of moving to the position shown in Figure 11.
When trip lever 92 has moved to the neutral position, the base portion 109 of above-mentioned bottom end surface 108 contact lock construction elements 91.Under this state, as shown in figure 11, trip lever 92 is attempted further to clockwise rotate under its deadweight effect.In other words, trip lever 92 is attempted along it the direction that lock construction element 91 promotes downwards to be rotated.But, because lock construction element 91 is subjected to the elasticity loading that above-mentioned helical spring 100 makes progress at any time, so lock construction element 91 can be separately owing to the weight effect of trip lever 92 not be moved, so lock construction element 91 protrudes upward from the top of door main body 89, and the position that engages with lock construction element mating holes 83 of maintenance.
But as shown in figure 12, if force this trip lever 92 is further rotated counterclockwise, for example, if attempt to change operating personnel's manipulation of print cartridge 63 and rotate trip lever 92, then trip lever 92 will move up to keeping flat the position.Move when keeping flat the position at trip lever 92, described bottom part 108 moves around described supporting pin 106 rotations, thereby promotes the described base portion 109 of lock construction element 91 downwards.Therefore, lock construction element 91 overcomes the elastic force of above-mentioned helical spring 100 and moves downward, and moves to the position that is withdrawn in the door main body 89.In case lock construction element 91 changes to this position, then door 76 locking is disengaged, and can make door 76 change into open position from the closed position.
Because lock construction element 91 is subjected to the elastic force of above-mentioned helical spring 100 consistently, so in case the revolving force that acts on the trip lever 92 disappears, in other words, in case operating personnel unclamp trip lever 92, then lock construction element 91 is taked the position of stretching out from door main body 89 maximums.Here, trip lever 92 is forced to move to above-mentioned standing place.That is to say that as shown in Figure 8, be shown in an open position when middle at door 76,92 of trip levers can be in the position that is accommodated in basically in the door main body 89.Therefore, as Fig. 1, Fig. 5 and shown in Figure 8, when changing print cartridge 63, trip lever 92 is in following state, that is, trip lever 92 is contained in the door main body 89 basically, thereby allow door 76 to turn to the approximate horizontal state, allow operating personnel to be easy to change print cartridge 63 thus around rotating shaft part 94.In addition, be arranged on the wall surface 84 of above-mentioned promotion retaining member 90 two projections 141 and 142 and described subsequently leader cooperation between sweep 97 also as at the guiding piece that print cartridge 63 is installed in when accommodating in the chamber 78.That is to say, print cartridge 63 is being inserted into when accommodating in the chamber 78, operating personnel only need the bottom surface of print cartridge 63 is placed on projection 141 and 142, and the leading edge portion of print cartridge 63 is placed between the sweep 97, only print cartridge 63 are promoted towards accommodating chamber 78 then.In addition, from accommodating chamber 78 when removing print cartridges 63, operating personnel only need pull out bottom surface up to print cartridge 63 from moving on projection 141 and 142 between the sweep 97.
In the present embodiment, because trip lever 92 is arranged in the above-mentioned neutral position in door 76 is in the closed position with respect to housing 75 time, promptly because trip lever 92 towards operating personnel's inclination, can be easy to handle trip lever 92 so its advantage is operating personnel.Now, because refill unit 70 is arranged on the front surface 71 of multi-function device 10, as shown in Figure 1, if trip lever 92 is arranged in place, described neutral position, if promptly it still turns forward, need guarantee that then bigger space is to hold refill unit 70 in multi-function device 10 inside.Therefore, refill unit 70 will need further inwardly to arrange from the edge of opening 73, therefore may need to increase the external dimensions of multi-function device 10.
But in the present embodiment, in the time of in door 76 is in the closed position with respect to housing 75, trip lever 92 can freely rotate between described neutral position and standing place, therefore refill unit 70 can be arranged near the edge of described opening 73.This be because: even refill unit 70 is arranged in the edge of opening 73, when open-close lid 72 is being closed, the inner wall surface of open-close lid 72 contacts described trip lever 92, and when open-close lid 72 was closed fully, trip lever 92 moved to described standing place when being promoted by open-close lid 72.Therefore, in the present embodiment, the Compact Design of multi-function device 10 is possible.
