IMAGE FORMING APPARATUS
First Claim
1. An image forming apparatus comprising:
- a main body;
a document board pivotably mounted to the main body so as to open and close an upper side of the main body while being pivoted; and
a shock absorber to reduce impact generated when the document board closes the upper side of the main body, wherein;
the shock absorber comprises a link pivotably mounted, at a first end thereof, to the document board while guide protrusions are formed at a second end thereof opposed to the first end, and a guide slot formed so that each guide protrusion is movable, and the guide protrusion moves from a first end side of the guide slot to a second end side thereof opposed to the first end side according to closing of the document board; and
the guide slot applies a pressure, which is gradually increased upon progression from the first end side of the guide slot to the second end side thereof, to the guide protrusion.

Abstract
An image forming apparatus includes a main body, a document board to open and close an upper side of the main body while being pivoted, and a shock absorber to reduce impact generated when the document board closes the upper side of the main body, wherein the shock absorber includes a link pivotably mounted, at a first end thereof, to the document board while guide protrusions are formed at a second end thereof, and a guide slot formed so that each guide protrusion is movable. Since the guide slot applies a pressure gradually increased from the first end side of the guide slot to the second end side thereof, to the guide protrusion, a speed of the guide protrusion and a pivoting speed of the document board are restricted below a certain speed when the upper side of the main body is closed through the document board.

9. An image forming apparatus comprising:
-
a main body; a document board pivotably mounted, at one end thereof, to the main body so as to open and close an upper side of the main body; and a shock absorber to reduce impact generated when the document board closes the upper side of the main body, wherein; the shock absorber comprises a link pivotably mounted, at a first end thereof, to the document board while guide protrusions are formed at a second end thereof opposed to the first end, and a guide slot formed so that each guide protrusion is movable, and the guide protrusion moves from a first end side of the guide slot to a second end side thereof opposed to the first end side according to closing of the document board; and the guide slot comprises a first guide portion arranged at the first end side of the guide slot to apply a first pressure to the guide protrusion, and a second guide portion arranged at the second end side of the guide slot to apply a second pressure higher than the first pressure to the guide protrusion. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. An image forming apparatus comprising:
-
a document board; and a shock absorber to reduce impact generated when movement of the document board opens and closes the image forming apparatus, wherein; the shock absorber comprises a link pivotably mounted, at a first end thereof, to the document board while guide protrusions are formed at a second end thereof opposed to the first end, and a guide slot formed in a guide member so that each guide protrusion is movable in the guide slot; and the guide slot applies a pressure to the guide protrusion, which is gradually increased upon progression of the guide protrusion from one end of the guide slot to the other end of the guide slot.
