Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an information input device for inputting multiple items of information to an information processing device through key operations, and particularly relates to an information input device for inputting multiple items of information into an information processing device by key operations, and particularly for rolling up multiple page sheets with input information into a roll. The present invention relates to an 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 Publication No. 159126/1983,'' published on December 15, 1974.

This consists 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 function indications of input keys are fixed at regular intervals on the circumference of the rotating shaft, and this is replaced with the main body of the device. It consists of a removable structure similar to a town Noh play. 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 section. 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 and presses a desired input key, the key signal from the input key is transmitted along with the page sheet identification signal from the page selection key and the page sheet member identification signal generated when the page sheet storage section is accommodated. It is encoded and input to the information processing device as input information. By the way, in this conventional device, in consideration of the replaceability of the page sheet members, the entire page sheet storage section is constructed as a cartridge, which can be attached and removed from the main body of the device. In reality, it includes four rotating shafts for spanning the endless belt that holds the page sheet in the winding direction, and a side plate that forms the storage case, and because it is heavy and large, it is difficult to replace it. This was troublesome and required a large space for security.

Furthermore, in the past, since the page sheet storage section was located below the keyboard section, the keyboard section had to be removed before replacement, which made handling cumbersome.
In order to solve these conventional drawbacks, the present applicant
We proposed a multi-item information input device (Japanese Patent Application No. 55-23135, -23136, 23137) effective February 26, 2013.

After automatically rotating the desired page sheet 140 by a predetermined angle as shown in the figure and winding up the desired page sheet 140 on the guide plate 75 (state in FIG. 13), the specified desired page sheet of this time is set in the state shown in FIGS. 10 and 14. be done.

Thereafter, the winding shaft 91 is driven to rotate in reverse as shown in FIGS. 11 and 15, and when the rotation by a predetermined angle is completed, the page of the desired page sheet 140 is selected as shown in FIG. 12. Next, the operation of exchanging the page sheet member 14 wound around the winding shaft 91 will be explained.

When replacing the page sheet member 14 in the state shown in FIG. 12, first the push button switch 5 dedicated to page sheet member replacement in the page selection key group A is switched.

Then, in the same way as described above, the winding shaft 91 is automatically rotated by a predetermined angle as shown in FIG. 10, passes through the winding state (the state shown in FIG. 13), and then is set to the state shown in FIG. 16. In FIG. 16, the other end of the first page sheet 140' passes through the guide plate 11 and is located in the guide passage 13, and the second end of the first page sheet 140'
The other end is locked to the shaft 94, which is the fifth
As explained in the figure, in this page sheet member 14, when winding, the first page sheet 140' and the last page sheet 1 are used.
This is obtained because 40〃 is the state in which one page sheet is removed. Then, from the state shown in FIG. 16, the winding shaft 91

Return to operating state. In this state, one end of the page sheet member 14 is led out from the exchange port 4, and the operator can easily remove it. 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. Along with this, the stepping motor 100 rotates in the forward and reverse directions by a predetermined number of steps to select a page or discharge and replace a page sheet member. Next, regarding the identification means for the selected page sheet, an example thereof is shown in FIG.
This will be explained with reference to FIG.

In FIG. 18, 152a and 154a are light emitting elements and light receiving elements for detecting the first row of holes 144 for page sheet identification, and 152b and 154b are light emitting elements for detecting the second row of holes 145 for page sheet identification. Light receiving element, 152
c and 154c' are light emitting elements and light receiving elements 156a and 156 for detecting the column holes 143 for page sheet member identification;
b, 156c, and 156d are inverter circuits; 157 is an AND circuit; 158 is a D-type flip-flop circuit whose D terminal is held at a constant potential H for temporarily suspending the page pulse generated by the first column hole 144; 159 is 15
160 is a D-type flip-flop circuit for temporarily holding the sheet member pulse generated by the identification column hole 143;
This is a counter circuit which is a storage means for counting the output signal from 60 using clock pulses of a constant period.

Further, in FIG. 19, the pulse waveform A is the output waveform of the inverter circuit 156a, B is the output waveform of the inverter circuit 156b, E is the output waveform of the inverter circuit 156c, C is the output waveform of the flip-flop circuit 158, and D is the AND Output waveform of circuit 157, F is flip-flop circuit 1
60 output waveforms.

In this identification circuit, the light receiving elements 154a, 154b, 1
54c operates when the light from the light emitting elements 152a, 152b, 152c passes through each hole of the first row hole 144, second row hole 145, and identification row hole 143, and sends a slit pulse corresponding to the slit width to the inverter circuit. 156a, 156b,
156c.

The output terminal Q of the flip-flop 158 is set by sequentially inputting the page pulses shown in FIG. 19A to the input terminal T. In addition, the clear pulses (the first
The reverse pulse train (in FIG. 9B) clears the Q output for each pulse in FIG. 19A, so that the output pulses as shown in FIG. 19c are sequentially input to the counter circuit 159 and counted. Flip like this. Since the flop 158 is set by the page pulse shown in FIG. 19A and sequentially cleared by the clear pulse shown in FIG. A
(7) Do not count extra pulses even when doing G). or,
When the flip-flop 160 receives the synchronized pulses E and C in FIG. 19 at its input/output terminals D and T, it sends out an output pulse as shown in FIG. 19F from its output terminal Q to the counter circuit 161. It is counted.

Furthermore, the first hole 144a of the first row hole 144 and the second row hole 14
Since the first holes 145a in FIG.
, B are generated, and by the pulses H and I, pulses as shown in FIG. 19D are input from the AND circuit 157 to the counter circuits 159 and 161.

This pulse is a resetting pulse by which the counts of the counter circuits 159 and 161 are reset at a constant cycle and set to the initial state. The identification signal in this identification circuit is generated by the pulses H and I of FIGS. 19A and B when the page sheet member 14 is hooked onto the winding shaft 91 and wound by page selection. The counter circuits 159 and 161 are set to the initial state by the first reset pulse of C.

From this state, the winding shaft 91 is controlled to rotate several times (two revolutions in the embodiment) until the page sheet member 14 is wound up and the desired page sheet set state as shown in FIGS. 10 and 14 is reached. During this winding, the counter circuit 161
is the flip-flop 1 based on the presence/absence data of the identification column hole 143 obtained in synchronization with the page pulse of FIG. 19A.
60 output pulses (FIG. 19F) are sequentially counted, and the count value until the next second reset pulse is applied is outputted to an external device as a page sheet member identification signal. still,
This identification signal is always output every time the page sheet member 14 rotates once. Similarly, the counter circuit 159, which is set to the initial state by the first reset pulse, is first set to the second reset pulse.
The output pulses of the flip-flop 158 (FIG. 19C) until the reset pulse is applied are sequentially counted, and this value is calculated based on the winding state of the page sheet member 14 (the page sheet member 14 is completely wound around the winding shaft 91). output to an external device as the state taken).

Then, the counter circuit 159, which was set to the initial state again by the second reset pulse, sequentially counts the output pulses of the flip-flop 158 until the third reset pulse is applied again, and this value is used to identify the selected page sheet. It is input to an external device as a signal. From this state, the counter circuit 159 calculates the number of output pulses of the flip-flop 158 until the winding shaft 91 rotates once in the reverse direction and the selected page sheets shown in FIGS. 10 and 14 are derived as shown in FIGS. 12 and 15. This value is counted and input to an external device as a page sheet display state. In this way, the counter circuit 1
59 sends out a page sheet member winding state signal, a selected page sheet identification signal, and a selected page sheet display state signal, and uses the selected page sheet identification signal and the page sheet member identification signal from the counter circuit 161 described above. The external device can identify which type of page sheet member is attached and which page sheet is selected, and this makes it possible to identify the code signal that is generated when the push button switch 5 is pressed. . The multi-item information input device according to the present invention has a cartridge configuration in which the page sheet member is detachably attached to the page selection reel and replaced, so that the cartridge is small and lightweight, and easy to handle, and can be stored easily. The space is also small.

Moreover, in the multi-item information input device of the present invention, at least two rows of transparent holes for page sheet identification are provided in the side portion of the base sheet, and each transparent hole in the first row hole and the second row hole in the two rows is provided with a plurality of transparent holes for page sheet identification. By arranging the light holes in a staggered pattern and detecting them with each sensor part, a page identification signal can be obtained by a combination of page pulses and clear pulses, and when page pulses occur frequently due to unnecessary external vibrations when selecting a page, etc. However, its practical effects are remarkable, such as being able to achieve more reliable page sheet identification without detecting extra pulses.
