Abstract
In a casing pivoting mechanism for a copying machine according to the present invention, the pivotal point of a casing is situated away from the position at which a torsion bar passes through the casing. By doing this, a greater urging force can be obtained with use of the same torsion bar as is used in a conventional mechanism. Also, the space within the casing can be widened for more effective utilization.
Claims2
A casing pivoting mechanism for a copying machine, comprising:
- a first casing block;
- a second casing block swingably coupled to the first casing block;
- and
- torsion bar means mounted between the first and second casing blocks, so as to urge the second casing block in a predetermined direction with respect to the first casing block,
- pivotal points of said first and second casing blocks being situated away from positions at which the torsion bar means passes through the first and second casing blocks,
- said torsion bar means being formed by twisting at least two torsion rods together at the middle portions thereof,
- one and the other end portions of one of said torsion rods engaging first engagement portions of the first and second casing blocks, respectively, and
- one and the other end portions of the other of said torsion rods engaging second engagement portions of the first and second casing blocks, respectively.
