DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a multi-item information input device for inputting multi-item information to an information processing device by key operations, and particularly relates to a multi-item information input device for inputting multi-item information into an information processing device by key operations, and in particular, a multi-item information input device for inputting multiple page sheets with input information into a roll. The present invention relates to a multi-item information input device which can be miniaturized and which can be rotated in forward and reverse directions to select and switch desired page sheets.

As a conventional device of this type, there is a multi-item information input device disclosed in ``Japanese Unexamined Patent Application Publication No. 159126/1983,'' published on December 15, 1974. This is composed of a page sheet storage section, a page sheet switching mechanism section, and a keyboard section for input operations. The page sheet storage section has a rolled page sheet member in which a plurality of flexible page sheets with input key function indications are fixed at regular intervals on the circumference of the rotation axis, and this is replaced with the main body of the device. It has a structure in which it is housed in a detachable manner as much as possible. Then, when the operator presses a desired page selection key on the keyboard section, the stepping motor of the page sheet switching mechanism section is activated, and the rotating shaft connected thereto is rotated at a predetermined angle in the opposite direction to the page sheet winding direction. After the desired page sheet is rotated and the other end surface of the desired page sheet is positioned at the page sheet output port to be in the set state, the rotating shaft is then rotated in the page sheet winding direction to input the desired page sheet into the keyboard unit. A function display is automatically displayed on the bottom surface of the key to provide a function display for the input key. In this state, when the operator looks at the function display through the keyboard and presses a desired input key, the key signal from the input key is converted into a page sheet identification signal from the page selection key and a page sheet generated when the page sheet storage section is stored. It is coded together with the member identification signal and input to the information processing device as input information. By the way, in this conventional device, since the desired page sheet is led out below the keyboard, the information items displayed on the page sheet are far away from the operator, and the operation directionality is strong, making it difficult to operate.

Next, the page selection operation of the above-mentioned Honda item information input device will be explained with reference to FIGS. 8 to 15. In this figure, the same reference numerals as those mentioned above represent the same contents.

First, regarding the winding operation of the page sheet member 14, first insert the desired page sheet member 14 into the guide passage 13 from the exchange port 4 as shown in FIG. It is brought into contact with the winding shaft 91 and set in a state in which winding is possible as shown in FIGS. 6 and 7.

Next, when the predetermined push button switch 5 of the page selection key group A corresponding to the selected page sheet 140 is pressed and switched, the stepping motor 100 is automatically driven as shown in FIG. 8, and the gear 101 is rotated in the direction of the arrow c. Then, the drive shaft 92 is rotated by a predetermined angle in the direction of arrow d via the gear 102. Also, the drive shaft 92
When the belt 93 rotates, the belt 93 rotates in the directions of arrows e and f, and the winding shaft 91 rotates by a predetermined angle in the direction of the arrow g. Furthermore, as the winding shaft 91 rotates, the page sheet member shown in FIG. 6 is rotated around the winding shaft 91 as shown in FIG. It is wound up. When the rotation of the winding shaft 91 by a predetermined angle in the g direction is completed, the desired page sheet 140 is set in a state where only the other end thereof is latched to the guide plate 11, as shown in FIGS. 8 and 12.

Subsequently, from this state, the stepping motor 10 is automatically activated.
0 is driven to rotate in the opposite direction, as shown in FIG.
1. The drive shaft 92, belt 93, and winding shaft 91 rotate in the direction opposite to that of FIG. 8 as indicated by arrows h, i, j, k, and l. When the winding shaft 91 rotates in one direction that is opposite to the winding direction (g direction) of the page sheet member 14, the desired page sheet 140 is moved in the direction of arrow m and other pages as shown in FIGS. 9 and 13. Sheet 140 is led out in the direction of arrow n. When the rotation of the winding shaft 91 by a predetermined angle in one direction is completed, the desired page sheet 14 is rotated as shown in FIG.
0 covers each push button switch 5 of the input key group B and is led out to a guide passage 76 on a guide plate 75 to give a function display to each push button switch, and the other page sheet 140 is accommodated in the guide passage 13. The page selection operation is completed.

When the other push button switch 5 of the page selection key group A is pressed from the state shown in FIG. 10, the winding shaft 91 automatically rotates by a predetermined angle as shown in FIG. After winding up the desired page sheet 140 (the state shown in FIG. 11), the specified current desired page sheet 140 is set to the states shown in FIGS. 8 and 12. After that, the winding shaft 91 is moved to the ninth
When the desired page sheet 140 is reversely rotated as shown in FIG. 13 and rotation by a predetermined angle is completed, the page of the desired page sheet 140 is selected as shown in FIG. 10.

Next, the page sheet member 1 is wound around the winding shaft 91.
The exchange operation of No. 4 will be explained.

When replacing the page sheet member 14 in the state shown in FIG. 10, first the push button switch 5 dedicated to page sheet member replacement in the page selection key group A is switched. Then, similar to the above, the winding shaft 91
is automatically rotated by a predetermined angle as shown in FIG. 8, passes through the winding state (the state shown in FIG. 11), and then is set to the state shown in FIG. 14. Figure 14 is the first page sheet 1 of the volume.
The other end of 40' passes through the guide plate 11 and is located in the guide passage 13, and the end of the roll page sheet 14
0″ other end is locked to the shaft 94,
As explained in FIG. 5, in this page sheet member 14, the first page sheet 140' is
This is obtained because one page sheet is removed between the end page sheet 140'' and the end page sheet 140''.
From the state shown in FIG. 14, the winding shaft 91 is driven to rotate in the reverse direction as shown in FIG. 13 and returns to the winding operation state shown in FIG. 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 control drive of the stepping motor 100 is as follows.
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 responds to a preset positive pulse (to move the winding shaft 91 in the winding direction G).
(pulse for rotating the winding shaft 9) and a negative pulse (pulse for rotating the winding shaft 9
1 in the reverse winding direction l) is continuously applied to the stepping motor 100. 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 ends of the base sheet 141 touch the support stands 151 and 153 of the sheet detection section 15.
However, at this time, a set of light emitting elements 152
and the light receiving element 154 to detect the identification hole 143,
This generates a predetermined page sheet member identification signal. Further, 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, thereby identifying a predetermined page sheet. A signal is generated. The page sheet member identification signal and the 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,
This designates the corresponding code registered in the memory within the encoder circuit, and the code signal is output to an external device.

As described above, the present invention has a structure in which only the page sheet member is replaced, unlike the conventional method.
The handleability is extremely improved, and an inexpensive and highly versatile multi-item information input device can be provided.

In addition, since the desired page sheet is led out above the input switch of the keyboard section, the information items on the page sheet are closer to the operator and easier to see.
Improved operability and stable page selection operations can be obtained.

Furthermore, since the lid that forms the selection page sheet guide path between the keyboard section and the keyboard section is made of a hard material, the distance between the paths can be easily made uniform, and unnecessary external forces caused by operational errors can be prevented by the lid. The practical effects of this are remarkable, as it is possible to prevent the paper from being directly added to the selected page sheet, and to suppress the occurrence of damage to the page sheet.
