<p>PURPOSE:To clearly detect the state of a movable sheet, and not to increase the manhour of an assembling or an adjustment by arranging a conduction element and a resistance element on a circumference centering a turning shaft, and connecting either of the two elements to an adjacent member according to the turning of the sheet. CONSTITUTION:Each of rotors 24-27 turns by the page-turning of each of movable sheets 6-9, and the adjacent member, that is, the member connected to other rotors 24-27, an interior side supporting body 22, or a stator 32, is switched from a conductor 59 to a resistor 60. And assuming that the resistance of the resistor 60 is, for example, as (r), a resistance RX is almost '0', but, when each of the movable sheets 6-9 is page-turned to a left tablet part 2 in order starting from the above state, the resistance RX changes in order as r 2r 3r 4r. At such a time, by supplying a constant current I with a constant current circuit consisting of a R1, a R2, and a Tr, a voltage V at a connecting conductor 45, that is, a terminal rises by a prescribed value according to the page-turning. And by supplying its output voltage V to an A/D converter 91, a digital value PD which represents the state of the page-burning at that time can be obtained.</p> |
