Toner cartridge having first protrusion that transmits sound by engaging second protrusion on image forming apparatus

1. A toner cartridge inserted in an image forming apparatus along a first direction said cartridge comprising:

a toner cartridge main body which includes an end surface provided along the first direction and contains toner therein;

a discharging opening provided adjacent to the end surface which discharges toner;

a shutter which is movable in accordance with the movement of the toner cartridge along the first direction to open/close the discharging opening; and

a first protrusion provided adjacent to the end surface to apply vibration to the toner cartridge and transmit sound by engaging a second protrusion provided in the image forming apparatus and changing the position relative to the second protrusion in accordance with the movement of the toner cartridge along the first direction, the first protrusion being protruded in a second direction perpendicular to the first direction and provided along a third direction perpendicular to the first direction and the second direction.

2. The toner cartridge of claim 1 , wherein the second protrusion is a flexible member.

3. The toner cartridge of claim 1 , wherein the first protrusion applies the vibration and transmits sound by friction between the first protrusion and the second protrusion.

4. The toner cartridge of claim 1 , wherein the first protrusion applies the vibration and transmits sound when the shutter completely opens the discharging opening.

5. The toner cartridge of claim 1 , wherein the first protrusion faces the second protrusion when the shutter slides with respect to the first direction.

6. The toner cartridge of claim 1 , wherein the first protrusion is a rigid body.

7. A toner cartridge inserted in an image forming apparatus along a first direction, said cartridge comprising:

first means for containing toner therein, the first means including an end surface provided along the first direction;

second means for supplying the toner, the second means being provided adjacent to the end surface which discharges toner;

third means for moving in accordance with the movement of the toner cartridge along the first direction to open/close the second means; and

fourth means for applying vibration to the toner cartridge and transmitting sound by engaging a fifth means provided in the image forming apparatus and changing the position relative to the fifth means in accordance with the movement of the toner cartridge along the first direction, the fourth means being provided adjacent to the end surface and protruded in a second direction perpendicular to the first direction and provided along a third direction perpendicular to the first direction and the second direction.

8. The toner cartridge of claim 7 , wherein the fifth means is a flexible member.

9. The toner cartridge of claim 7 , wherein the fourth means applies the vibration and transmits sound by friction between the fourth means and the fifth means.

10. The toner cartridge of claim 7 , wherein the fourth means applies the vibration and transmits sound when the third means completely opens the second means.

11. The toner cartridge of claim 7 , wherein the fourth means faces the fifth means when the third means slides with respect to the first direction.

12. The toner cartridge of claim 7 , wherein the first means is a rigid body.

13. An image forming apparatus, which has a toner cartridge inserted therein along a first direction, said apparatus comprising:

a toner cartridge main body which includes an end surface provided along the first direction and contains toner therein;

a discharging opening provided adjacent to the end surface which discharges toner;

a shutter which is movable in accordance with the movement of the toner cartridge along the first direction to open/close the discharging opening;

a first protrusion which is provided adjacent to the end surface and protruded in a second direction perpendicular to the first direction and provided along a third direction perpendicular to the first direction and the second direction, the first protrusion applying vibration to the toner cartridge and transmitting sound by engaging a second protrusion; and

the second protrusion which is provided in the image forming apparatus and engages with the first protrusion and changes the position relative to the first protrusion in accordance with the movement of the toner cartridge along the first direction.

14. The image forming apparatus of claim 13 , wherein the first protrusion applies the vibration and transmits sound by friction between the first protrusion and the second protrusion.

15. The image forming apparatus of claim 13 , wherein the first protrusion applies the vibration and transmits sound when the shutter completely opens the discharging opening.

16. The image forming apparatus of claim 13 , wherein the second protrusion faces the first protrusion when the shutter slides with respect to the first direction.

17. The image forming apparatus of claim 13 , wherein the second protrusion is provided along the third direction.

18. The image forming apparatus of claim 13 , wherein the second protrusion is a flexible member.
