Abstract: A camera module includes a housing, a reflective member positioned in the housing and changing a direction of light to a direction of an optical axis, a carrier carrying the reflective member and rotatable about a first axis with respect to the housing, and a first ball group disposed between the housing and the carrier, wherein the first ball group includes a main ball member providing the first axis of the carrier, and an auxiliary ball member disposed away from the first axis, and one or both of the housing and the carrier partially accommodates the auxiliary ball member, and includes an auxiliary guide groove extended in a circumferential direction of the first axis.

Abstract: A folded module includes a housing, a carrier provided in the housing, and a rotation holder provided on the carrier and including a reflective member. The carrier is rotatable, with respect to the housing, around a first axis formed by one rotating shaft ball, the rotation holder is rotatable with respect to the carrier around a second axis formed by two ball members, and the first axis and the second axis intersect each other, and the one rotating shaft ball and the two ball members are provided together on a plane on which both the first axis and the second axis are provided.

Abstract: A cleaning apparatus include a cleaning member to remove a waste toner remaining in a photoconductive medium and a housing to support the cleaning member, including a waste toner admission portion to provide a transfer path of the waste toner removed by the cleaning member, and a waste toner collecting portion to store the waste toner. The housing has a first thickness corresponding to the waste toner admission portion and a second thickness corresponding to the waste toner collecting portion so that the first thickness is smaller than the second thickness.

Abstract: An image developing apparatus includes an upper case; a lower case disposed on a lower side of the upper case, and internally housing a developing agent, and having an opening. A photoconductive drum is disposed on the upper case for forming an electrostatic latent image on a surface thereof. A charging roller is disposed on one side of an outer circumference of the photoconductive drum for charging the photoconductive drum. A developing roller having one part is exposed through the opening of the lower case to cooperate with the photoconductive drum for developing the electrostatic latent image. A scattering preventing unit disposed between the photoconductive drum and the developing roller, to prevent scattering of the developing agent supplied by the developing roller. The scattering preventing unit includes a blocking curtain which covers a part of the opening and having one side in contact with the outer circumference of the photoconductive drum.

Abstract: A developing unit includes a waste toner housing having an upper housing and a lower housing which face each other, at least one support unit to allow connection between the upper and lower housings, and to support facing surfaces of the upper and lower housings, and a toner housing which is disposed on a lower part of the waste toner housing and is spaced apart from the waste toner housing at a predetermined distance. Accordingly, the waste toner housing is prevented from being deformed by heat and pressure, and thus white lines on images, flowback of waste toner and insufficient cleaning, which are caused by interference with the light path due to deformation of the waste toner housing, can be reduced. Additionally, tolerance can be greatly reduced as a result of resolving the problem of deformation of the waste toner housing, so a developing unit having a smaller size can be provided.
