A cart includes a projecting load receiving platform mounted on a slide frame in turn mounted for vertical movement on a main frame. In addition, the fluid ejector head includes a sacrificial material filling the chamber that is planarized to the plane formed by the passivation surface. The disks are superior in mechanical properties and reliability. If a call origination is attempted from a phone connected to an access gateway, the SM will instruct the network to handle the call differently depending on whether the services should be offered based on the class 5 switch or the SM. This thermal oxide film is thereafter removed at least in an element forming region. The control unit switches directions of movement of the first carriage based on a result output from the home position sensor when the image reading device is returned to an active mode from an energy-saving mode, and detects a distance of movement of the first carriage based on the pulse.
