Abstract: An operation panel is integrated into a conveying unit, and the operation panel and a conveying roller are displaced with respect to each other in a sheet width direction crossing a sheet conveying direction. The operation panel and the conveying roller are located in a manner at least partly overlapping each other in the sheet conveying direction and a height direction in the conveying unit. Further, the operation panel and the conveying roller are at least partly located within a range of a width of a sheet conveying area by the conveying unit.

Abstract: An image forming apparatus includes a frame in which a carriage configured to reciprocate along a predetermined direction is disposed, and a unit disposed to be openable with respect to the frame. A first engaging portion is formed on the image forming apparatus. The image forming apparatus is capable of restricting a movement of the carriage at least in the predetermined direction with use of a securing component including a second engaging portion engageable with the first engaging portion. When the securing component is attached to the carriage, and then the unit is closed with the first engaging portion and the second engaging portion engaging with each other, the securing component is sandwiched and fixed between the frame and the unit.

Abstract: A part engaging structure having sufficient intensity while reducing the use amount of material, and having high positioning accuracy is provided. An engaging structure allows a protruding portion formed at a first part to be received by a receiving portion formed at a second part and engages the first part with the second part. The protruding portion is formed of a structure body having a plurality of ribs combined in a polygonal shape lacking part of sides, and at least two of corner portions of the polygon of the structure body contact an inner surface of the receiving portion.
