is reversely rotated as shown in FIG. 16, and when the rotation by a predetermined angle is completed, the page sheet member 14 is discharged into the guide passage 13 and returns to the initial winding operation state. In this state, one end of the page sheet member 14 can be led out from the exchange port 4 and removed by the operator. Next, electrical control of the Honda item information input device will be schematically explained.

First, the stepping motor 100 is controlled and driven, and this is performed by a motor control circuit (not shown) mounted on the printed board 73.

That is, when the push button switch 5 of the page selection key group A is switched, the motor control circuit correspondingly generates a preset positive pulse (pulse for rotating the winding shaft 91 in the winding direction g) and a negative pulse. (pulses for rotating the winding shaft 91 in the reverse winding direction 1) are continuously transmitted to the stepping motor 1.
Apply to 00. In conjunction with this, the stepping motor 100 rotates a predetermined number of steps in the forward and reverse directions to select a page or discharge a page sheet member. On the other hand, multi-item information is output to an external device by a keyboard encoder circuit mounted on the printed board 73.

That is, when the page sheet member 14 is rolled up, the end of the base sheet 141 is introduced between the support stands 151 and 153 of the sheet detection section 15, but at this time, one set of light emitting elements 152
The identification hole 143 is detected by the light-receiving element 154, and a predetermined page sheet member identification signal is thereby generated. or,
The other set of light emitting elements 152 and light receiving elements 154 detect the detection hole 144 within the range in which the winding shaft 91 rotates by a predetermined angle when the push button switch of the page selection key group A is pressed, and thereby a predetermined page sheet identification signal is generated. . The page sheet member identification signal and page sheet identification signal are input to the keyboard encoder circuit together with the input key signal generated when the push button switch of input key group B is pressed, and thereby the corresponding code is registered in the memory in the encoder circuit. is specified, and the code signal is output to an external device. According to the present invention described above, since the desired page sheet is led out above the input switch of the keyboard section,
Since the information items on the page sheet are closer to the operator and easier to see, operability is improved and stable page selection operations can be achieved. Further, since the desired page sheet is guided upward, there is no need to use a special input switch such as a transparent switch, and an inexpensive device can be obtained.

Moreover, in the present invention, the winding shaft is rotated through the belt using the belt hanging shaft as the drive shaft, so if the operator sticks his finger on the desired page sheet or some heavy object is placed on the page sheet. Its practical effects are remarkable, such as when an abnormal load is placed on the page sheet due to the state in which the page sheet is placed, the winding shaft automatically slips, thereby eliminating damage to other parts.
