Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an input device that allows an operator to efficiently input various types of data to a processing device without having to worry about coding or complicated operations.

That is, the present invention is an input device in which each key of a group of data keys is defined by a display displaying the names of various items of data to be input, and by changing this definition, various data can be input.

Each time the definition of a group of data keys is changed, this input device treats this as a page and specifies the input data based on the page information and the defined data key, and if the data is of a greater variety, multiple pages are combined into one book. Alternatively, a plurality of files may be provided, and information from the book or file, page information, and data key may be used to specify the information.

The present invention relates to such an input device, and particularly to a system in which a display body defining each key of a group of data keys is moved between reels by a drive mechanism to change the definition of a group of data keys and to select a page. This allows the target page to be accurately stopped at a predetermined position for key definition.

That is, after the target page is stopped at a predetermined position for key definition, it is subsequently checked again whether the target page is at the predetermined position.

As shown in FIG. 1, the drive mechanism for the display in this type of input device is such that reels (take-up rollers) 2 and 3 are linked to drive motors 4 and 5, respectively, and the display 1 is moved between the reels 2 and 3. to drive the reel.

For example, by driving the drive motor 4 (stopping the drive motor 5) and winding up the display body 1 with the reel 2 (using the reel 3 as a feed reel), the display body 1 moves in the direction of arrow A, and vice versa. By driving the drive motor 5, the display body 1 moves in the direction of arrow B.

6 and 7 indicate rollers. Then, when the display body 1 is moved, each page of each key definition item page written on the display body 1 is read by an optical reader consisting of a light emitting element 8 and a light receiving element 9, and the drive mechanism is stopped by reading the target page. It is something that makes you

In the case of such a reel drive system, the reel diameter changes equivalently depending on the amount of display material wound on the reel, causing a change in speed, and the inertia of the reel also changes, so it is difficult to locate the desired position. Even if you control the motor or apply a mechanical brake to stop the motor immediately, it is very difficult to bring the motor to a predetermined stop position, and the stop position fluctuates.

In this display, key definition items are written and data keys are defined in relation to keys, so if the stop position of the display changes as described above, the relationship between key definition items and data keys will change in various ways. This has the serious problem of not being able to accurately define data keys.

Therefore, in this type of input device, there is a need for a device that can accurately control the display body to a stop position.

The present invention was proposed in order to solve the above-mentioned problems associated with this type of input device, and the present invention will be described in detail below.

FIG. 2 is a configuration diagram of the display body. Names of various items of data to be input in the longitudinal direction are displayed on the display body 1, and input items are displayed as pages in order to change the definition of a group of data keys. It is divided into many groups, and one person and one person have it.
B is that page.

A page mark (page code) 21.2 indicating each page in relation to the key definition item pages IA, IB...
1 . . . and stop position timing marks 22, 22 . . . for issuing a deceleration instruction and a stop instruction.

The stop position timing mark 22 is a mark having a constant length 1) in the longitudinal direction of the display body 1.

On the other hand, an optical mark reading device for detecting the page mark 21 and the stop position timing mark 22 is provided in connection with the display body 1.

As is clear from FIG. 3, this configuration has light emitting diodes 31a to 31e for page marks at positions corresponding to the page marks 21 above where the display body 1 passes, and light emitting diodes 31a to 31e for page marks at positions corresponding to the mark 22 for stop position timing. mark 22
Light emitting diodes 32a and 32b for stop position timing are provided with an interval 1 having a length of 1).

On the other hand, in the lower part L through which the display body 1 passes, there are light receiving diodes 33a to 33e and 34a, 34 corresponding to the light emitting diodes 31a to 31e and 32a, 32b.
Set b and L.

Then, from the light emitting diode 32a and the light receiving diode 34a, the signal TA is also transmitted to the other 32b, 3.
A signal TB is derived from 4b.

FIG. 4 shows a control circuit configuration for controlling the display 1,
FIG. 4 will be explained below.

2.3 is a reel (take-up roller) for moving the display body 1, and drive motors 4 and 5 are arranged in correspondence with each other.
Driven by.

When the display body 1 is moved in the direction of arrow A, the drive motor 4 is driven, and the reel 2 is used as a take-up reel and the reel 3 is used as a feed reel.

At this time, the drive motor 5 is stopped.

Further, when the display body 1 is moved in the direction of arrow B, the drive motor 5 is driven, and the reel 3 is used as a take-up reel, and the reel 2 is used as a feed reel.

41 is a drive circuit for the drive motor 4, and 42 is a drive circuit for the drive motor 5.

Both drive circuits 41 and 42 are supplied with voltage via a control transistor 44 from a voltage source 43 that causes high-speed rotation, and are also supplied with voltage via a control transistor 46 from a voltage source 45 that causes low-speed rotation. .

The control transistor 44 controls the supply from the voltage source 43 in response to the gate output of the AND gate 47, and the control transistor 46 controls the supply from the voltage source 45 in response to the gate output of the AND gate 48. do.

Reference numeral 50 denotes a counter in which page information (target page information) regarding the desired key definition item page of the display 1 is stored.

51 is the page mark reading device (light emitting diodes 31a to 31e and light receiving diodes 33a to 3) shown in FIG.
The information of the current key definition item page defining the current data key group from 3e) is introduced from line L1, and the current page information is sequentially stored as the display body 1 moves. .

A comparator 52 compares the target page information of the counter 50 with the current page information of the counter 51 and derives a control signal for controlling the drive mechanism based on the comparison result.

That is, when the information from the counter 50 is A and the information from the counter 51 is B, when A>B, line L2
A high level signal is derived from the line L3 when A<B, and a high level signal is derived from the line L4 when A=B.

Line L2 of the comparator 52 instructs the drive circuit 41 to drive, and line L3 instructs the drive circuit 42 to drive.

Further, the line L4 is introduced through the AND gate 47 and the inverter 58, and is also input to the AND gate 48.

On the other hand, the counter 51 presets the current page information from the line L1 when there is an input signal from the OR gate 55, and counts up by introducing the output from the AND gate 53 when the display body 1 moves. The countdown is performed by introducing the output from 54.

The signal from line L2 and the TA signal shown in FIG. 3 are introduced to the input side of this AND gate 53.

Further, the signal from line L3 and the TB signal shown in FIG. 3 are introduced to the input side of AND gate 54.

Also, as input signals to the OR gate 550, the gate output from the AND gate 56 and the signal A output when the power is turned on.
TA is introduced on the input side of this AND gate 560.
, TB signal and ■ signal output from the control section are introduced.

As will be described later, the AND gate 56 serves as page confirmation instruction means for outputting an instruction signal for re-executing page confirmation.

Therefore, at the beginning of the operation, the counter 51 is set with the current page information from the line L1 by the signal AC, and then as the display body 1 moves, the display body 1 is moved in the direction of the arrow A when the comparator 52 indicates that A>B. In response to the detection of the signal TA, the AND gate 53 becomes conductive, and this output counts up and stores the current page information sequentially, and the comparator 52 detects that A<B.
When the display body 1 is moved in the direction of arrow B at the time of , the AND gate 54 becomes conductive in response to the detection of the signal TB, and this output counts down to sequentially store the current page information.

Reference numeral 57 denotes an AND gate that switches and controls the voltage sources 43 and 45 by using the analog gates 47 and 48 and the control transistors 44 and 46, and the signal from the line L4 and the TA and TB signals are introduced to the input side of this AND gate. A signal obtained by inverting this gate output is introduced into the input sides of ant-games 47 and 48, respectively.

The operation of this control circuit configuration will now be briefly explained.

When the power is turned on during operation, an AC signal is output to instruct the counter 51 to read the current page information via the OR gate 55.

In response to this instruction, counter 51 introduces and stores current page information from line L1.

Then, when the operator specifies a desired page, the control section causes the page information to be introduced and stored in the counter 50.

As a result, the comparator 52 compares the current page information of the target page information and the lines L2, L3, . A control signal is output to either L4.

Now, assuming that the relationship between the information A of the counter 50 and the information B of the counter 51 is A>B, a signal is output to the line L2 to instruct the drive circuit 41 to operate.

In addition, the input line from the AND gate 57 to the AND gates 47 and 48 is h because the line L4 is at a low level.
Since the signal is at a high level and the signal from the line L4 via the inverter 58 is at a high level, the AND gate 47 becomes conductive and turns on the transistor 44.

Therefore, the voltage is supplied from the voltage supply source 43 to the drive circuit 41, driving the drive motor 4, and the display body 1 moves in the direction of arrow A.

In this case, since the voltage supply source 43 is used for driving, high-speed driving is performed.

By this movement of the display body 1 in the direction of arrow A, the light emitting diodes 32a, 32b and the light receiving diodes 34a, 34
When the stop position timing mark 22 is read by b, and the comparator 52 shows that A>B, when the light emitting diode 32a and the light receiving diode 34a output the TA signal, the AND gate 53 becomes conductive and the signal is sent to the counter 51. The TA signal is introduced and counts up.

In other words, the counter 51 counts up and stores current page information every time a TA signal arrives.

Thereafter, when the comparator 52 detects A=B, the line L4 is set to high level.

At this time, the light emitting diode 32a and the light receiving diode 34
a is the stop position timing mark 2 on the target page
This is when the TA signal is derived when 2 is read (
This TA signal is input to the counter 51 and the comparator 52 detects A-B), but since the light emitting diode 32b and the light receiving diode 34b are not yet in a state to read the stop position timing mark 22, the TB signal is not output.

Therefore, since the lines from the AND gate 57 to the AND gates 47 and 48 are at a high level, the AND gate 48 becomes conductive and the transistor 46 is turned on.

(At this time, the AND gate 47 is in a non-conductive state, and the transistor 44 is turned off.

) Therefore, the voltage is supplied from the voltage supply source 45 to the drive circuit 41, and the drive motor 4 is switched from high speed drive to low speed drive.

The display body 1 is moved at a low speed in this manner, and then the light emitting diode 32b and the light receiving diode 34b read the stop position timing mark 22 and the TB signal is output.

As a result, L4 and TA are on the input side of the AND gate 57.
, TB go high, and the line from AND gate 57 to AND gate 47.48 goes low.
level.

Therefore, AND gates 47 and 48 are both rendered non-conductive and transistors 44 and 46 are turned off, thereby cutting off power supply to drive circuit 41 and performing a stop operation.

In this case, the display body 1 is in a state where it is necessarily changed from high-speed movement to low-speed movement, and since the stopping operation is performed after this low-speed movement, the reel 2, 30 penetration is also small, so it is forced to stop immediately. be able to.

In other words, it can be accurately stopped at a desired position.

This display body 1 is stopped at a desired position, and the target page defines a group of data keys. At this point, for confirmation once again, the ■ signal is derived from the control section and the AND gate 56
conduction.

The AND gate 56 responds to a signal indicating the stopped state of the display body 1, that is, the TA and TB signals output when a predetermined page of the display body 10 is positioned at the stopped position, and receives an instruction signal ( This page confirmation instructing circuit means outputs a gate output).

This gate output is sent to the counter 51 via the OR gate 55.
is input to.

The counter 51 receives and stores current page information from line L1 in response to the input signal, and outputs the current page information to the comparator 52 again.

As a result, the comparator 52 compares the contents of the counters 51 and 50, and if A=B, this stopped state is maintained, and if A<
If B or A>B, the drive circuit will be controlled again.

The above page confirmation operation is performed when the count value of the current page information malfunctions (+1 or -l increase or decrease from the actual page information) due to noise etc. when the page selection means positions the display object to the target page at high speed. In some cases, even if the comparison circuit detects a match and stops the display, a page different from the desired page (a page located one page more or less than the desired page position) may be selected and the target page may not be selected. This is to avoid this problem, which occurs frequently.

Therefore, the page information (page code) where the display object is actually positioned in the page confirmation operation is fed back, and this fed back page information (page code) is compared again with the specified target position information to confirm the actual position. This allows you to confirm whether the target page of the display has been selected.

Note that when the comparator 52 detects A<B, a drive instruction is given to the drive circuit 42 to move the display body 1 in the direction of arrow B, and the AND gate 54 becomes valid and T
The counter 51 counts down every time the B signal arrives.

FIG. 5 shows another embodiment of the display body 1 shown in FIG. 2, in which a black printed portion 1 is provided on the side edge of the display body 10, and a key definition item page IA is provided in this portion.

A transparent page mark 21 indicating the page and a stop position timing mark 22.degree. 22 may also be provided in association with 1B, . . . .

As described above, the data input device of the present invention is provided with page marks that provide coded page information (page code) corresponding to each page of the display body, and is also provided with a detection means for detecting the page marks, as well as a detection means for detecting the page marks. In response to the destination page instruction for the key definition item page of the display body, the drive mechanism moves the display body in the direction of the target page by comparing the current key definition item page information and the target page information, and the display body is moved to the target page. The page selection means for controlling the key to the defined position sets the page information by the above-mentioned detection means when the power is turned on, and also performs a count-up or count-down operation by 1 for each page detected when the display body is moved. /Includes a down counter, a counter to which inputted target page information is set, and a comparator to which information from both of the counters is inputted, and causes the movement of the display object to be stopped based on the detection of coincidence by the comparator. Further, after the page selection means stops the display body upon detection of a match by the comparator, the page selection means again compares the page information at the stop position with the target page information based on the stopping operation. The device is equipped with a page confirmation instruction circuit that outputs an instruction signal to display the page, and after controlling the display to stop, feeds back page information (page code) where the display is actually positioned, and specifies the page information designated as the fed-back page information. By comparing the target position information again and confirming whether the target page of the display object is actually selected, the display object can be accurately stopped at the desired position. This makes it possible to accurately correspond to key definitions, thereby contributing to improved operability for the operator.
