Claims

[Claims for Utility Model Registration] 1. A device comprising a device body and an opening/closing housing attached to the device body so as to be able to freely pivot between an open position and a closed position, and the opening/closing housing includes a pinion portion that rotates integrally with the device body. is provided, and a rack is mounted on the main body of the device that engages with the pinion portion and moves as the pinion portion rotates, and the biasing force that biases the opening/closing housing toward the open position is applied to the device body. A housing opening/closing mechanism characterized in that the housing opening/closing mechanism is configured to operate easily. 2. The housing opening/closing mechanism according to claim 1, wherein the device main body is provided with a support shaft, and the pinion portion of the opening/closing housing is rotatably mounted on the support shaft. 3. The rack is in a first position when the opening/closing housing is in the closed position, and is located in a second position when the opening/closing housing is in the open position, and the rack is not moved beyond the second position. The housing opening/closing mechanism according to claim 1 or 2, which is provided with a blocking means for preventing the above. 4. The housing opening/closing mechanism according to any one of claims 1 to 3, wherein the rack is connected to a biasing means for biasing the opening/closing housing toward the open position.
