Description

[Detailed Description of the Invention] This invention relates to a multi-item information input device in which a plurality of flexible sheets on which items are written are used to input a large number of item information, and in particular, the flexible sheet The present invention relates to a multi-item information input device that prevents mistakes in selecting flexible sheets even when the thickness of the sheet changes, and allows only desired flexible sheets to be delivered to an input section.

As is well known, a sheet-replaceable multi-item information input device, which is one type of input device, increases the number of items that can be input by using multiple flexible sheets with items written on them, and when used, The system is configured to inform the operator of input items by selecting a desired one from among these flexible sheets and presenting it on the input board surface, as shown in Figure 1a. A flexible sheet 1 _-1 , ..., 1 _-o on which a large number of items are written is wrapped around a winding frame 2 and stored.
When in use, these flexible sheets 1 are rotated in the direction opposite to the storage direction as shown in FIG.
_-1 , ..., 1 _-o is rewound, a desired one is separated by the separation rod 3, and it is fed out to the input section 6 consisting of a transparent film 4 and a switch sheet 5, and the operator It is designed to present items that can be entered.

By the way, in such a multi-item information input device 7, the side plates 9, 10 of the conventional sheet storage case 8
Fixed pulleys 14, 15, 16 are rotatably supported on shafts 11, 12, 13 fixed to A movable pulley 18 rotatably supported at the tip of an arm 17 presses the guide belt 19 against the winding frame 2 around which the flexible sheets 1 _-1 to 1 _-o are wound. Since I was trying to hold down the flexible sheets 1 _-1 to 1 _-o ,
When the thickness of each flexible sheet 1 _-1 to 1 _-o is increased, the sheet portion 21 consisting of the winding frame 2 and the flexible sheets 1 _-1 to 1 _-o is thickened as shown in Fig. 2a. The winding diameter becomes larger. Therefore, in this case, the fixed pulleys 15 and 16 on the separating rod 3 side press the periphery of the sheet portion 21 via the guide belt 19, so a large torque is required when rotating the winding frame 2. Moreover, if the winding diameter of the sheet portion 21 is even larger, it becomes impossible to rotate the winding frame 2.

Furthermore, when the thickness of the flexible sheets 1 _-1 to 1 _-o is made thinner, the winding diameter of the sheet portion 21 becomes smaller as shown in FIG. A triangular gap 2 between 16 and 16
3 and 24 are formed, the winding frame 2 is rotated in the direction of arrow B until the end of the desired flexible sheet, for example, the flexible sheet 1 _-1 comes off the fixed pulley 15, and then the winding frame 2 is rotated. When the desired flexible sheet 1 _-1 is fed out by rotating in the direction opposite to arrow B, the flexible sheet 1 _-o corresponding to the page before this flexible sheet 1 _-1 is inserted into the gap 23. At this point, the flexible sheet 1 _- o was no longer restrained by the fixed pulley 15, and the flexible sheet 1 _-o was unrolled overlapping the flexible sheet 1-1.

In view of the above points, this invention is capable of keeping the driving torque of the reel constant even when the thickness of the flexible sheet changes, and also allows the flexible sheet to be turned over excessively and unrolled double. It is an object of the present invention to provide a multi-item information input device that can prevent users from being
