Sheet feed device and image forming apparatus

A sheet feed device comprising:

• a housing having a side;
• a sheet storing portion configured to store one or more sheet members;
• a conveyance path formed inside the housing and configured to guide a sheet member conveyed from the sheet storing portion;
• an outside cover rotatably supported with a lower end thereof as a fulcrum by the housing, and configured to be positioned at a first closing position to close the side of the housing, and at a first opening position to open the side of the housing;
• an inside cover disposed more inside of the housing than the outside cover and rotatably supported with a lower end thereof as a fulcrum by the housing, and configured to be rotationally moved between a second closing position at which to close the conveyance path when the outside cover is at the first closing position, and a second opening position at which to expose the conveyance path when the outside cover is at the first opening position;
• a coupled portion provided on the inside cover and configured to be coupled with the outside cover;
• a first coupling portion provided on the outside cover and configured to, when the outside cover is rotationally moved in an opening direction from the first closing position toward the first opening position, be coupled with the coupled portion and cause the inside cover to be rotationally moved toward the second opening position, and after the inside cover starts to be rotationally moved toward the second opening position, release coupling with the coupled portion;
• and
• a second coupling portion provided on the outside cover and configured to, when the outside cover is further rotationally moved toward the first opening position after the first coupling portion releases the coupling with the coupled portion, be coupled with the coupled portion and hold the outside cover at the first opening position.
