An image playback apparatus has a recording section which records shot images, and a display section which displays the images. The system and method extend the common mode voltage range of functional devices beyond the supply rails of the functional device, while keeping the differential signal loss to a minimum. The motor may be activated by a processor based on the control signal provided by the remote control. A coupling arrangement connects the front portion to the rear portion so that when the front portion is in the raised position along the seat back the front portion is in the lowered position, in which at least part of it is retracted under the rear portion. The adjusting member holds a distal portion of the cartridge at a distance with respect to a distal portion of the cartridge holder.
