发明名称 OPTICAL SCANNING APPARATUS AND IMAGE FORMING APPARATUS INCLUDING THE OPTICAL SCANNING APPARATUS
摘要 A leaf spring includes a first pressing portion that presses a reflection mirror supported by a mirror support, and an engagement portion that engages with an engagement portion provided on a housing. In a first state in which the engagement portions are engaged with each other, the first pressing portion presses the reflection mirror so that the reflection mirror is urged against the mirror support. When a state of the leaf spring is being changed to the first state from a second state in which the engagement portions are not engaged with each other, the leaf spring comes into contact with the engagement portion provided on the housing and rotates such that the engagement portion provided on the housing serves as a fulcrum.

主权项 1. An optical scanning apparatus comprising: a light source configured to emit a light beam; a deflector configured to deflect the light beam emitted from the light source so that a photoconductor is scanned with the light beam; an optical member configured to guide the light beam deflected by the deflector to the photoconductor; a housing configured to accommodate the light source, the deflector, and the optical member and including an engagement portion and an optical member supporting portion configured to support the optical member; and a leaf spring including a pressing portion configured to press the optical member supported by the optical member supporting portion, and including an engagement portion configured to engage with the engagement portion provided on the housing, the pressing portion presses the optical member so that the optical member is urged against the optical member supporting portion in a first state in which the engagement portion provided on the leaf spring is engaged with the engagement portion provided on the housing, wherein, when a state of the leaf spring is being changed to the first state from a second state in which the engagement portion provided on the leaf spring is not engaged with the engagement portion provided on the housing, the leaf spring comes into contact with the engagement portion provided on the housing and rotates such that the engagement portion provided on the housing functions as a fulcrum.
