Claims

[Scope of Claim for Utility Model Registration] A lid that is rotatable between a closed position that covers the front operation panel of the device and an open position that faces the bottom of the device; A lid opening/closing mechanism for an operation panel comprising a rotation mechanism for rotating between a lid position and an open lid position, wherein the rotation mechanism is comprised of a motor, a worm gear mechanism comprising a worm and a worm wheel, and a worm. a rotating body that is provided coaxially with the worm on a fixed shaft that supports the worm and is rotated by the motor; a spring member that biases the rotating body toward the worm; A friction clutch formed between the worm and the worm makes the worm movable in the axial direction about the fixed shaft, and the axial force acting on the worm changes the direction of rotation of the worm during the lid opening operation. A lid opening/closing mechanism for an equipment operation panel configured to face in the opposite direction to the body.
