So, because the shaft sleeve part 80 of the first lid 79 embeds in the second acceptance division 45B of the sidewall 36L of left, the shaft sleeve part 82 of development electrode 81 embeds in the second acceptance division 45B of the sidewall 36R of right, and therefore, the leading section of Delevoping cartridge 20 is moved downwards along with the flexure of the rearward end of drum box 1.
So the leading section of Delevoping cartridge 20 is contrary with the rearward end of Delevoping cartridge 20, move in the mode of floating upward relative to the leading section of drum box 1.
At this moment, as mentioned above, although the sticking department 54 in the locked portion 78 and securing rod 33 that there is Delevoping cartridge 20 situation about abutting, but, because securing rod 33 is limited to rock counterclockwise when front is seen, therefore, it is possible to guarantee that the leading section limiting Delevoping cartridge 20 is moved upward further.
7, technique effect
(1) above-mentioned bulging box 1, as shown in Figure 9, when securing rod 33 is positioned at latched position, securing rod guide portion 44 abuts with the right surperficial 53A in the posterior end portion of the lifting parts 53 of securing rod 33.
Thereby, it is possible to the front of restriction securing rod 33 rotates counterclockwise when seeing, can prevent from losing the cooperation of sticking department 54 relative to the locked portion 78 of Delevoping cartridge 20 of securing rod 33.
Consequently, the disengaging of Delevoping cartridge 20 from Delevoping cartridge installation portion 43 can stably be limited.
(2) above-mentioned bulging box 1, as shown in Figure 9, in the opposition side of the sidewall 36L of the left of support lock fixed pole 33, by securing rod guide portion 44, can limit rocking of securing rod 33.
Therefore, by clamping between the sidewall 36L and securing rod guide portion 44 of left, rocking of securing rod 33 can efficiently be limited.
(3) above-mentioned bulging box 1, in the situation of figure 9, when the leading section of Delevoping cartridge 20 is moved upward, the locked portion 78 of Delevoping cartridge 20 abuts with the sticking department 54 of securing rod 33.
So, securing rod 33 be subject to from the locked portion 78 of Delevoping cartridge 20 with the fitting portion 55 of turning axle 51 be fulcrum viewed from front time counterclockwise power.
At this moment, the interference ribs 56 of securing rod 33 abuts with the right surface of the sidewall 36L of the left of drum framework 31.So the operating portion 52 of securing rod 33 is limited to move to the left further.The posterior end portion of the lifting parts 53 of securing rod 33 abuts with the left surface of the securing rod guide portion 44 of drum framework 31.So the lifting parts 53 of securing rod 33 is limited to move to the right further.
Thereby, it is possible to limit rocking of securing rod 33 by above-below direction two side of the turning axle 51 of securing rod 33.
Consequently, can guarantee further to limit rocking of securing rod 33.
(4) above-mentioned bulging box 1, as shown in Figure 10 A, the distance D1 between the central axis A2 of the turning axle 51 of the securing rod 33 and rearward end 54A of sticking department 54 is shorter than the distance D2 between the central axis A2 of the turning axle 51 of securing rod 33 and the right surperficial 53A in the posterior end portion of lifting parts 53.
Therefore, as shown in Figure 9, when under the state being positioned at latched position at securing rod 33, the sticking department 54 of the 78 pairs of securing rods 33 in locked portion of Delevoping cartridge 20 applies power upward, can abut with the securing rod guide portion 44 of drum framework 31 than the right surperficial 53A of sticking department 54 from the posterior end portion of the farther lifting parts 53 of turning axle 51.
Therefore, the right surperficial 53A in the posterior end portion of lifting parts 53 is more farther from turning axle 51 than sticking department 54, can correspondingly with the power that the power applied than the Delevoping cartridge 20 pairs of sticking departments 54 is less, rocks counterclockwise when the front limiting securing rod 33 is seen.
Consequently, rocking of securing rod 33 can be limited efficiently further.
(5) above-mentioned bulging box 1, as shown in Figure 10 B, the lifting parts 53 of securing rod 33 is positioned at the top of securing rod guide portion 44 when being positioned at latch-release position.
Therefore, it is possible to do not occur with securing rod guide portion 44 to make securing rod 33 be positioned at latch-release position intrusively.
Consequently, securing rod 33 can be made smoothly to turn to latch-release position from latched position.
(6) above-mentioned bulging box 1, as shown in the enlarged view in Fig. 1, the rearward end of securing rod guide portion 44 has guide portion 44A, and guide portion 44A is along with forwards and to the left tilting.
Therefore, when securing rod 33 rotates from latch-release position to latched position, by guide portion 44A, the left of securing rod 33 to securing rod guide portion 44 can be guided.
Consequently, securing rod 33 can be made to rotate from latch-release position to latched position smoothly.
(7) above-mentioned bulging box 1, as shown in Figure 7 and Figure 8, when Delevoping cartridge 20 has been arranged on Delevoping cartridge installation portion 43, drum box grip part 42 has configured across compartment of terrain in the front of Delevoping cartridge grip part 76.
Therefore, when installing or unload bulging box 1 relative to apparatus body 12 etc., when the bulging box 1 of Delevoping cartridge 20 has been installed in operation, there is the situation not gripping separately bulging box grip part 42 together with Delevoping cartridge grip part 76.
In this case, because drum framework 31 bends, the cooperation of sticking department 54 relative to the locked portion 78 of Delevoping cartridge 20 of securing rod 33 may easily be lost.
But, even if in this case, as mentioned above, due to rocking of securing rod 33 can be limited by securing rod guide portion 44, depart from therefore, it is possible to stably limit Delevoping cartridge 20 from Delevoping cartridge installation portion 43.
