PURPOSE:To replace sheets members one by one and on the whole, and to simplify the structure of an input device by fitting sheet members detachably by a sheet holder, and winding free ends of the members around nearly the same circumference. CONSTITUTION:A pin 33 provided to the channel-sectioned holder 32 of the sheet holder 31 of a multiitem information input equipment is run through two holes 2b made at one end of sheet members 2; the tip of the pin 33 is fitted in a pin receptacle 34, and one-side ends of the members 2 are held stacked. A sheet- wound rotary body 41 is a rotary drum which increases in the radius of the circumferential surface graudally during one turn in the circumferential direction, and on the boundary line between a mximum and a minimum radius part, a stepped part 42 high enough to match with the holder body 32 is formed. At the upper part of the stepped part 42, a groove 43 is formed, and a locking member 35 and a coupling part 36 provided on the back surface of the member 2 are stored while exposed from the circumferential surface of the rotary drum. Thus, the one-by-one and simultaneous replacement of the members 2 is facilitated to simplify the structure of the input device. |
