2, the action of present embodiment and effect
As mentioned above, in the laser printer 1, when toner cartridge 40 was not in the toner cartridge container cavity 71 in the development section 30 that is installed on processing unit 20 (hereinafter being called " toner cartridge 40 is installed in the processing unit 20 ") this state, the opening/closing lever 113 of processing unit 20 did not engage with each side direction teat 54 of the inner housing 42 of toner cartridge 40.The rotation of this restriction inner housing 42, thus can prevent that the inner peripheral wall 51 of inner housing 42 from inadvertently opening and closing first toner discharging opening 49 of shell body 41.
When toner cartridge 40 is installed in the processing unit 20, each side direction teat 54 engages with opening/closing lever 113 its corresponding carriers 117, and inner housing 42 each second radially teat 57 and toner cartridge container cavity 71 gate 111 its corresponding to be joined 139 engage, clip gate 111 thus.
This state allows, activity with opening/closing lever 113, rely on side direction teat 54 to rotate inner peripheral wall 51, promptly open and close first toner discharging opening 49, second teat 57 and the 3rd teat 63 Rotary grates 111 radially radially with dependence combines with side direction teat 54 promptly open and close toner guiding port 88.
Therefore, when toner cartridge 40 is in installment state in processing unit 20, when opening/closing lever 113 moves to the lever open position, the inner peripheral wall 51 of inner housing 42 turns to the toner open position, gate 111 turns to the developer open position, and toner guiding port 88 and 49 openings of first toner discharging opening.This allows the toner guiding port 88 and first toner discharging opening 49 to communicate with each other, allow the inside of toner cartridge 40 its inner housings 42 and the inside in development section 30 its development chambeies 72 to communicate with each other in addition, thereby toner can be supplied in the development chamber 72 of processing unit 20 from toner cartridge 40.
When toner cartridge 40 is in the state that is installed on the processing unit 20, opening/closing lever 113 moves to the lever off-position, make inner peripheral wall 51 and gate 111 turn to toner off-position and developer off-position respectively, thereby the toner guiding port 88 and first toner discharging opening 49 are intercepted.This prevents that toner from leaking when allowing toner cartridge 40 to remove in the middle of the processing unit 20 in the middle of the toner guiding port 88 and first toner discharging opening 49.
When toner cartridge 40 is in the state that removes in the middle of processing unit 20, gate 111 be not sandwiched in toner cartridge 40 second radially teat 57 and the 3rd radially teat 63 is between the two, therefore, even if opening/closing lever 113 actions, gate 111 can not rotate yet, thereby toner guiding port 88 can keep intercepting.Inner peripheral wall 51 does not rotate when toner cartridge 40 is in the state that removes in the middle of processing unit 20 as mentioned above as for 40 of toner cartridges, thereby first toner discharging opening 49 can keep intercepting.
Therefore, can prevent that toner cartridge 40 and processing unit 20 from leaking with simple composition.
In addition, can be provided with each side direction teat 54, each second teat 57 and each the 3rd teat 63 this simple composition radially radially, described opening and closing action above realizing with toner cartridge 40 to first toner discharging opening 49 and toner guiding port 88.
Thereby, under toner cartridge 40 is installed on state in the processing unit 20, each side direction teat 54, each second radially teat 57 and the 3rd radially teat 63 can make inner peripheral wall 51 and gate 111 stable rotation.When inner housing 42 rotations are opened for making first toner discharging opening 49, each side direction teat 54, each second radially radially not interference of 63 pairs first toner discharging opening of teat 49 of teat 57 and the 3rd, thereby this first toner discharging opening 49 and guiding port 88 can reliably be communicated with each other, and toner is supplied to the development chamber 72 of processing unit 20 from toner cartridge 40 reliably thus.
In addition, the inner housing 42 with inner peripheral wall 51 is that each outside edge wall 46 supports in rotatable mode by the two side of shell body 41 on Width, can stablize thus to open and close first toner discharging opening 49.
In sum, inner peripheral wall 51 and gate 111 are supported in two lateral ends sides of toner cartridge 40 and processing unit 20 respectively with rotary way, thereby first be not provided with extra mechanism in escape hole 49 and the guiding port 88, thus toner cartridge 40 and processing unit 20, be that first escape hole 49 and guiding port 88 can be combined closely under toner cartridge 40 is installed on state in the processing unit 20 each other specifically.Therefore, in this configuration, toner leakage may take place between the two in toner cartridge 40 and processing unit 20 hardly.In addition, in this configuration, have a space to be formed at two side (right wall 69 and the left wall 70) central part between the two of developer housing 62 in the processing unit 20, toner cartridge 40 can more easily pass in and out this processing unit 20 during toner cartridge 40 was installed and removed with respect to processing unit 20.
In addition, when processing unit 20 was in installment state in main casing 2, toner cartridge 40 can be installed and remove with respect to processing unit 20.Specifically, the toner cartridge container cavity 71 that holds toner cartridge 40 is arranged at the front side of processing unit 20, thereby opens when making installing port 6 open when the protecgulum 7 of main casing 2, and toner cartridge 40 exposes in the middle of installing port 6.
Thereby when for replaced color powder box 40 toner cartridge 40 being installed and removing with respect to main casing 2, for instance, processing unit 20 does not need to install and remove with toner cartridge 40, improves operability thus.
In addition, toner cartridge 40 is provided with guiding lever 44, because guiding lever 44 restriction inner peripheral walls 51 did not rotate when toner cartridge was in installment state in processing unit 20, thereby can eliminate this worry of the inner peripheral wall 51 undesirable rotations of generation, first toner discharging opening 49 can keep intercepting, and can prevent that toner from leaking in the middle of toner cartridge 40.On the other hand, under toner cartridge 40 is installed on state in the processing unit 20, the restriction that inner peripheral wall 51 rotates is removed by guiding lever 44, thereby first toner discharging opening 49 is open, toner can be supplied to the development chamber 72 of processing unit 20 reliably from toner cartridge 40.
Guiding lever 44 comprises wobble component 92, and this wobble component 92 can be swung at first state and second state between the two with the clamping force of wobble component 92.Under first state, first junction surface 132 of first restrictions 94 of wobble component 92 and inner peripheral wall 51 the 4th radially teat 94 engage, and under second state, the rearward end of second restrictions 95 of wobble component 92 and the inner peripheral wall 51 of inner housing 42 connect, and can limit inner peripheral wall 51 thus and rotate.Under first state and second state third state between the two, first junction surface 132 and the 4th radially teat 99 joint between the two discharges, and the rearward end of second restrictions 95 does not connect with the inner peripheral wall 51 of inner housing 42, can remove the restriction that inner housing 42 is rotated with respect to shell body 41 thus.
