Patent ID: 8219020

Claim:
An image forming apparatus comprising: a housing having an image forming part configured to form an image on a recording sheet and an ejection portion configured to eject the recording sheet on which an image is formed; an upper sheet receiving portion disposed on an upper surface of the housing and configured to receive the recording sheet ejected from the ejection portion; a side sheet receiving portion disposed on a side of the housing and configured to receive the recording sheet ejected from the ejection portion; an extended sheet receiving portion configured to be attachable to and removable from both of the upper sheet receiving portion and the side sheet receiving portion; a first guide part disposed facing the ejection portion and configured to guide the recording sheet ejected from the ejection portion; and a second guide part disposed on the side sheet receiving portion and having a first state and a second state, the second guide part being configured to guide the recording sheet guided by the first guide part to the upper sheet receiving portion when in the first state and to guide the recording sheet guided by the first guide part to the side sheet receiving portion when in the second state, wherein, when the second guide part is in the first state, the second guide part engages the first guide part, wherein, when the second guide part is in the second state, the second guide part is disengaged from the first guide part and disposed downstream of a most downstream end of the first guide part in a direction in which the recording sheet is ejected, wherein the upper sheet receiving portion is configured to pivotally support the extended sheet receiving portion such that the extended sheet receiving portion pivots between a first position where the extended sheet receiving portion is retracted and a second position where the extended sheet receiving portion protrudes from the upper sheet receiving portion in the direction in which the recording sheet is ejected, wherein the side sheet receiving portion is configured to pivotally support the extended sheet receiving portion such that the extended sheet receiving portion pivots between a third position where the extended sheet receiving portion protrudes from the side sheet receiving portion in the direction in which the recording sheet is ejected and a fourth position where the extended sheet receiving portion is retracted, wherein, when the second guide part is in the first state, the upper sheet receiving portion and the extended sheet receiving portion in the second position receive the recording sheet ejected from the ejection portion, and wherein, when the second guide part is in the second state, the side sheet receiving portion and the extended sheet receiving portion in the fourth position receive the recording sheet ejected from the ejection portion.
