A cleaning device includes a blade member, a holder, a vibration detection device, a heating device, and a control device. The exemplary sensing system includes an aperiodic fiber grating with an alternative refractive index modulation for such multi-function sensing and determination. In this way, the present invention realizes an information processing apparatus capable of easy modification of the setting image for setting printing conditions. The optical glass preferably has a yield point within a range from 550\xb0 C. The flexible element may be conformable to the natural spinal movement.
