Abstract

A sheet accommodating device includes a housing; a sheet accommodating portion configured to accommodate a sheet and detachably mountable in the housing, the accommodating portion including, a supporting member supporting the accommodating portion so as to be rotatable relative to the housing, a movable member movable relative to the supporting member along the supporting member, a first urging member urging the movable member in a moving direction of the supporting member, a regulating member movable in a direction crossing with the moving direction of the movable member, and a second urging member urging the regulating member so as to protrude it from the movable member. The housing is provided with an engageable member engaged with the regulating member.

First claim

What is claimed is:

1 . A sheet accommodating device comprising:
a housing; a sheet accommodating portion configured to accommodate a sheet and detachably mountable in said housing, said sheet accommodating portion including, a supporting member supporting said sheet accommodating portion so as to be rotatable relative to said housing, a movable member movable relative to said supporting member along said supporting member, a first urging member urging said movable member in a moving direction of said supporting member, a regulating member movable in a direction crossing with the moving direction of said movable member, and a second urging member urging said regulating member so as to protrude it from said movable member, wherein said housing is provided with an engageable member engaged with said regulating member.

2 . A sheet accommodating device according to claim 1 , wherein said supporting member includes a support rail extending along a mounting and dismounting direction of said sheet accommodating portion.

3 . A sheet accommodating device according to claim 1 , wherein said first urging member includes a spring having one end portion fixed to said supporting member and the other end portion fixed to said movable member.

4 . A sheet accommodating device according to claim 3 , wherein said first spring is compressed by contacting between said engageable member and said regulating member.

5 . A sheet accommodating device according to claim 4 , wherein said regulating member includes an accommodation regulating portion projecting from said regulating member, and said accommodation regulating portion being contactable to a lower guide portion provided on said supporting member.

6 . A sheet accommodating device according to claim 5 , wherein said accommodation regulating portion is in contact with said lower guide portion in a state that engageable member and said regulating portion are in contact with each other and said first spring is compressed.

7 . A sheet accommodating device according to claim 6 , wherein said movable member is provided with an opening capable of accommodating said accommodation regulating portion.

8 . An image forming apparatus comprising:
a main assembly; an image forming station provided in said main assembly and configured to form an image on a sheet; a feeding unit configured to feed the sheet to said image forming station; a sheet accommodating device configured to accommodate the sheet fed to said feeding unit, said sheet accommodating device including, a sheet accommodating portion configured to accommodate a sheet, said sheet accommodating portion including, a supporting member supporting said sheet accommodating portion so as to be rotatable relative to the main assembly, a movable member movable relative to said supporting member along said supporting member, a first urging member urging said movable member in a moving direction of said supporting member, a regulating member movable in a direction crossing with the moving direction of said movable member, and a second urging member urging said regulating member so as to protrude it from said movable member, wherein said main assembly is provided with an engageable member engaged with said regulating member.

9 . An apparatus according to claim 8 , wherein said supporting member includes a support rail extending along a mounting and dismounting direction of said sheet accommodating portion.

10 . An apparatus according to claim 8 , wherein said first urging member includes a spring having one end portion fixed to said supporting member and the other end portion fixed to said movable member.

11 . An apparatus according to claim 10 , wherein said first spring is compressed by contacting between said engageable member and said regulating member.

12 . An apparatus according to claim 11 , wherein said regulating member includes an accommodation regulating portion projecting from said regulating member, and said accommodation regulating portion being contactable to a lower guide portion provided on said supporting member.

13 . An apparatus according to claim 12 , wherein said accommodation regulating portion is in contact with said lower guide portion in a state that engageable member and said regulating portion are in contact with each other and said first spring is compressed.

14 . An apparatus according to claim 13 , wherein said movable member is provided with an opening capable of accommodating said accommodation regulating portion.
