摘要： A paper supplying deck is insertable into and withdrawable from a paper supplying portion of a body resulting in electrical connection between the side of the paper supplying deck and the side of the body through a drawer-type connector when the paper supplying deck is inserted and interruption of such electrical connection when the drawer is withdrawn. The paper supplying deck has a paper carrying portion with a paper width setting mechanism and a variable resistor the resistance value of which is changed in dependence on the paper width setting mechanism, thereby changing an output paper width detecting voltage. On the wide of the paper supplying deck, a resistance which prevents the paper width detecting voltage from amounting to a power source voltage even though the resistance value of the variable resistor reaches a maximum value, is connected in series with the variable resistor. On the side of the body, a pull up resistance is connected with the connector to discriminate between voltages in the connector when the paper supplying deck is mounted and when the paper supplying deck is not mounted.

摘要翻译： 供纸台可插入和取出主体的供纸部分，当供纸台插入并中断时，通过抽屉式连接器在供纸台的一侧和主体的侧面之间电连接 当抽屉被抽出时，具有这种电连接。 供纸台具有带纸宽度设定机构的纸张承载部分和可变电阻器，其电阻值根据纸张宽度设定机构而改变，从而改变输出纸张宽度检测电压。 在供纸盘的宽度上，即使可变电阻器的电阻值达到最大值，阻止纸张宽度检测电压达到电源电压的电阻与可变电阻器串联连接。 在本体的一侧，当连接器供纸台安装时以及没有安装供纸台时，上拉电阻与连接器连接以区分连接器中的电压。
