Abstract
An image forming apparatus includes LED heads protected from scratching. An optical head is mounted on an inner side of a lid pivotally mounted to a body of the apparatus. A protector is mounted to the lid. A mechanism is operatively coupled to the lid such that when the lid is positioned at an open position, the protector is at a protection position where the lid covers a light-emitting surface of the optical head and when the lid is positioned at an exposure position, the protector is at an exposure position where the lid does not cover the light-emitting surface of the optical head is. When the lid is pivoted past a position at which the lid forms an angle with the body, the mechanism begins to cause the protector to move from the protection position toward the exposure position.
Claims17
An image forming apparatus comprising:
- a body;
- a lid pivotally mounted to said body, said lid being positioned either at a first position where said lid closes an opening formed in said body or a second position where said lid opens the opening;
- an optical head mounted on an inner side of said lid;
- a protection member mounted to said lid, said protection member being positioned either at a third position where said lid covers a light-emitting surface of said optical head or at a fourth position where said lid does not cover the light-emitting surface of said optical head;
- a mechanism operatively coupled to said lid such that when said lid is pivoted relative to said body, said mechanism causes said protection member to be positioned either at the third position or at the fourth position;
- wherein when said lid is positioned at the first position, said protection member is at the fourth position;
- wherein when said lid is pivoted to a position at which said lid forms an angle with said body, said mechanism begins to cause said protection member to move from the third position toward the fourth position;
- Wherein when said lid is positioned at the second position, said protection member is at the fourth position.
An image forming apparatus comprising:
- a body;
- a lid pivotally mounted to said body, said lid being positioned either at a first position where said lid closes an opening formed in said body or a second position where said lid opens the opening;
- a light emitting diode head mounted on an inner side of said lid;
- a protection member mounted to said lid, said protection member being positioned either at a third position where said lid covers a light-emitting surface of said optical head or at a fourth position where said lid does not cover the light-emitting surface of said optical head;
- a mechanism operatively coupled to said lid such that when said lid is pivoted, said mechanism causes said protection member to be positioned either at the third position or at the fourth position;
- wherein when said lid is closed at the first position, said protection member is at the fourth position;
- wherein when said lid is pivoted to a position at which said lid forms an angle with said body, said mechanism begins to cause said protection member to move from the first position toward the fourth position;
- Wherein when said lid is pivoted to the second position, said protection member is at the fourth position.
