Under the situation in the fixator 8 that recording medium cartridge 100 is inserted recording medium drive device, the locking protrusion 108 (Fig. 5) that provides in the engagement protrusion 115b of the locking bar 115 of closer 110 and the mechanism's part 106 of container 101 is meshed, and closer 110 is locked to make-position, is used for closed light hole 101h.
When opening the lid 5 of electronic installation 1, fixator 8 rotates and enters the state (Fig. 8) that can insert recording medium cartridge 100 with respect to frame 7 simultaneously on pivot.
When beginning that recording medium cartridge 100 inserted the fixator 8 of recording medium drive devices, for example as shown in figure 18, when recording medium cartridge 100 is inclined upwardly slightly with respect to fixator 8, the surrounding edge of the container 101 of recording medium cartridge 100 contacts the double duty stiffening rib 30e of the front end place formation that connects surface 30 slidably, and recording medium cartridge 100 is imported into fixator 8.Therefore, recording medium cartridge 100 can insert fixator 8 reposefully.
When beginning with recording medium cartridge 100 insertion fixators 8, for example as shown in figure 19, when recording medium cartridge 100 is downward-sloping slightly with respect to fixator 8, the surrounding edge of the container 101 of recording medium cartridge 100 contacts receiving trap 35 slidably, guiding surface 35a and 35a or guiding surface 44 that 35 upper end forms, 44 (Figure 14), and recording medium cartridge 100 is imported into fixator 8.As a result, recording medium cartridge 100 can be inserted into fixator 8 reposefully.
When beginning with recording medium cartridge 100 insertion fixators 8, further when downward-sloping at recording medium cartridge 100 with respect to fixator 8, as shown in figure 20, the receiving portion 35b that the arc surface 101a contact of container 101 admits the inside end place on surface 35 and 35 to form, 35b, so recording medium cartridge 100 is not inserted into fixator 8.As a result, the user can understand recording medium cartridge 100 and inserted fixator 8 mistakenly.In addition, receiving portion 35b, 35b form the curved surface of recurvate gracefulness, so that can avoid admitting the destruction or the scratch of surface 35,35 and container 101.
When beginning with recording medium cartridge 100 insertion fixators 8, for example as shown in figure 21, recording medium cartridge 100 with respect to fixator 8 on the left and right directions skew or when left and right directions tilts, the arc surface 101a of container 101 contacts the insertion guide 31b and the 32b of the front end place formation of side 31 and 32 slidably, and recording medium cartridge 100 is imported into fixator 8.
Even not being provided with, the side 31 of fixator 8 and 32 places do not insert guide 31b and 32b, when beginning with recording medium cartridge 100 insertion fixators 8, when recording medium cartridge 100 on left and right directions with respect to fixator 8 skew or when tilting, recording medium cartridge 100 sliding contact sides 112,112 leading edge imports fixator 8 with recording medium cartridge 100.
Recording medium cartridge 100 inserts fixator 8 from above-mentioned arc surface 101a, but there are interval and container 101 to have arc surface 101a in the middle of protuberate 33 and 34, therefore as shown in figure 22, recording medium cartridge 100 tilts with the back state downward slightly with respect to fixator 8 sometimes.But, because contacting of recording medium cartridge 100 and bridge joint protuberate 33 and 34 protrusion detent 43 prevented the protrusion towards the bottom of fixator 8.In addition, be arranged at and be right after before the recoding/reproduction unit that constitutes by optical pickup apparatus 18, dish platform 16 etc. owing to protrude detent 43, avoided between container 101 and the recoding/reproduction unit contact and can be by the reliability of this recoding/reproduction cells to improve recoding/reproduction operation.Again, protruding detent 43 is arranged near the core between the side 31 and 32 of fixator 8, so the part that is easy to most protrude downwards in container 101 as the core of left and right directions contacts with protruding detent 43, to prevent the downward protrusion of recording medium cartridge 100 from space between protuberate 33 and 34 reliably.
When recording medium cartridge 100 was inserted into fixator 8 and contact protrusion detent 43, as shown in figure 23, container 101 sliding contact continuously protruded the second guide 43b and the first guide 43a of detent 43 and is rearwardly guided.As a result and since container 101 with protrude contacting of detent 43, can suitably and reliably recording medium cartridge 100 be inserted fixators 8, and not hinder the smoothly mobile of recording medium cartridge 100 in the fixator 8.
Opposite with above description, sometimes when being inserted into fixator 8 as shown in figure 24 the state that makes progress slightly with the back of recording medium cartridge 100 tilt.At this moment, the end edge sliding contact of the upside of the arc of container 101 surface 101a connects the basal surface of the core on the left and right directions on surface 30, i.e. the basal surface of part 30d, but the stiffening rib 37 that this part 30d place not have formation to be recessed into.As a result, the end edge of the upside of container 101 will can not enter any recessed stiffening rib 37 and hinder in the fixator 8 the level and smooth of recording medium cartridge 100 to move.Recording medium cartridge 100 can be suitably and is inserted the constant intensity that fixator 8 is kept fixator 8 simultaneously at least reliably.
In addition, as shown in figure 25, form the open side stiffening rib 38 of the edge of opening place formation of the opening 30a that connects surface 30, so that with the opposite side of first and second protuberates 33 and 34 on outstanding, so the end edge of the upside of container 101 contact openings side stringer 38 and can guarantee that the level and smooth of recording medium cartridge 100 move not.
Among Figure 26, when recording medium cartridge 100 was further inserted fixator 8, the closer opening member 32d that side 32 places of fixator 8 are provided inserted the insertion groove 105 of recording medium cartridge 100.At this moment, the release prodger 42 of the closer spring 40 that adheres on the side 32 of fixator 8 is reduced on the outside surface of side 112 of closer 110 and slides on side 112.As a result, make closer spring 40 elastic deformations.
As shown in figure 27, when recording medium cartridge 100 is further inserted fixator 8, the back of the body edge of the side 112 of closer opening member 32d contact closer 110.Simultaneously, the release prodger 42 that rides up on the side 112 of closer 110 is inserted functional hole 112a by the recovery of elasticity of spring 41.When release prodger 42 was inserted functional hole 112a, the promotion part 115a of locking bar 115 was pushed by release prodger 42, and locking bar 115 pivots at the bias force of bias spring.As a result, discharge engagement protrusion 115b and the engagement that locks protrusion 108, and discharge the locking of the closed position of closer 110.
At this moment, as shown in figure 28, except closer opening member 32d, also the posture keeper 32e that the back is provided with inserts the insertion groove 105 that forms in the container 101.As a result, therefore closer opening member 32d and the posture keeper 32e media box 100 of flatly holding the record in fixator 8 can guarantee the suitable insertion state of recording medium cartridge 100.
In addition, closer opening member 32d reduces number of components except being maintained fixed the unit of the posture of recording medium cartridge 100 in the device 8 as also being used as the unit of opening closer 110 simultaneously thereby can improve function.
As shown in figure 29, when the locking of the closed position that discharges closer 110, the back edge of closer opening member 32d contact side 112, therefore when from here with recording medium cartridge 100 further during insertion fixator 8, closer 110 relatively moves forward with respect to container 101, and opens closer 110.
When recording medium cartridge 100 is inserted fixator 8, protrusion prevents that the engagement protrusion 39b of spring 39 from temporarily inserting the engagement recess 101j that forms among the side 101b, but edge of opening the moving and the first sloping edge 39c of sliding contact engagement protrusion 39b backward of the front side of engagement recess 101j by recording medium cartridge 100, spring 39a is outwards departed from, and will mesh protrusion 39b and take out engagement recess 101j.
As shown in figure 30, finish under the state that is inserted into fixator 8 at recording medium cartridge 100, closer 110 moves to open position.As mentioned above, by toggle spring 109, closer 110 is at the direction upper offset opposite with above direction of insertion, and closer 110 is held in aperture position.
As shown in figure 31, finish under the state that is inserted into fixator 8 at recording medium cartridge 100, protrusion prevents that the engagement protrusion 39b of spring 39 is inserted into the release recess 101k that forms among the side 101b.As a result, protrusion prevents that the bias force of spring 39 is not applied to the container 101 of recording medium cartridge 100, and can avoid preventing the unwanted tension force of spring 39 to recording medium cartridge 100 from protrusion.
