Drawing apparatus

摘要

An image forming apparatus is provided that can surely position a unit in an apparatus body with a simple configuration where the number of components is small. A drawing apparatus, which draws a sheet feeding cassette as a unit to a predetermined position of the apparatus body to position it, includes : a leaf spring that is an elastic member to jump-buckle; an engaging unit disposed in the leaf spring; and an engaged unit engaged with the engaging unit. When the unit is loaded on the apparatus body, the engaging unit engages the engaged unit, the elastic member jump-buckles, and accordingly the unit is drawn to the predetermined position of the apparatus body.
