A scopes heating device includes a bag having first seal lines that divides the bag into a first chamber at one side and a second chamber at an opposite side, a heat storage/release material accommodated in the bag and flowing between the first chamber and the second chamber for storing/releasing heat energy, a fixation device mounted on the bag for securing the bag in a folded condition where the first chamber and the second chamber are stacked up, and an actuator bendable to generate oscillation waves for causing the heat storage/release material to produce a temperature rise and then to release heat for pre-heating scopes that are set between the first chamber and the second chamber after the bag having been folded up.
