<p>PROBLEM TO BE SOLVED: To make a recording device small-sized and lightweight and improve its operability when only the recording device is used by feeding the electric power for driving the recording device from a feeding device. SOLUTION: A power supply unit is large and heavy within units constituting a recording device 1 and a feeding device 2. It is desirous to make the recording device 1 lightweight in weight and small in size by providing no power supply unit on the recording device 1 in consideration of the portability of the recording device 1 and its installation at various installation sites for use. When the recording device 1 is used at a place near the feeding device 2, the power supply unit 10 of the feeding device 2 is utilized, a simple cord unit is used, thus cost performance is improved. When the recording device 1 must be used at a place apart from the feeding device 2 eventually, a power supply adapter can be separately prepared for use. The recording device 1 can be made small-sized and lightweight, and its operability for transportation and installation is improved at a low cost.</p> |
