PURPOSE: A pop-up device is provided to prevent damage even when an opening angle between an upper plate and a lower plate is bigger than 90 degrees and to minimize separation between the upper plate and the lower plate when the pop-up device is folded. CONSTITUTION: A pop-up device comprises the first stage part(1300) and a fixing means. The fixing means fixes the first stage part, an upper plate(1100), and a lower plate(1200) to be opened. The fixing mean comprises a stage front plate(1330), a stage side plate(1320), and a stage support plate(1350). A stage support plate is connected with an end on the inner side of the stage side plate and on one side of the first stage plate comprising the side of the first stage part. The side is adhered to be fixed and the other end is extended to be fixed on the first stage lower surface. On the stage support plate, a recess(1351) is formed as a part of the left and right inside of the front end is receded. |
