PURPOSE:To easily connect the electrical transmission systems of paper supply units which are freely extended in a device main body by making the best use of the merit of plastic which is light in weight and inexpensive and which can be variously molded. CONSTITUTION:The paper supply units 25 and 26 formed of the structure body made of the plastic are provided at the lower part of the device main body 1 so as to be freely extended and coupled. Besides, electrical contact parts 28 and 33 for transmitting signals which are brought into contact with and connected to the device main body 1 side or the signal supply means 31 and 32 of the preceding unit 25 are directly formed at one part of the units 25 and 26. Thus, the connection of the electrical transmission systems can be also secured only by extending and coupling the unit 25 or 26 and the need of the troublesome connection of a harness is eliminated. |
