Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a document reading device for reducing the occurrence of a strong visual effect called techno-stress ophthalmopathy of the operator when inputting by keyboard operation of OA equipment such as a word processor and a personal computer.

[0002]

[Prior Art]

 Generally, the input work of OA equipment is separated by looking at the screen of the visual display terminal (hereinafter abbreviated as VDT), looking at the keyboard, and searching for the characters to be input in the text of the manuscript. It gazes at an object placed in a closed position, which is extremely demanding on the worker's eyes. It is said that this work requires about 2.5 times more frequent eye movements than ordinary office work.

In the case of a Japanese word processor, there are many cases where three types of characters, Japanese and Western, are mixed in the sentence, and especially when the kana character conversion or the roman character conversion is performed, the correct conversion to kanji characters is not performed smoothly. Unlike the English typewriter, you cannot operate the keys while looking at the manuscript alone, and you must operate it while observing the screen. Also, it is necessary to judge whether the kanji is correct or not, so psychological stress is also an important task.

Except for a skilled key puncher, many word processors and personal computer users have to repeat the motion of shaking their heads to see a document placed at a distance, and the body moves accordingly, so that the keyboard is not operated. The position of the fingers of the player is easy to shift, and it is necessary to use nerves to squeeze the keys closely.

The Japan Ophthalmologist Association has named various symptoms caused by the rapid spread of OA devices such as personal computers and word processors as “technostress ophthalmopathy”, and has established a research group therefor. In terms of occupational health, one continuous work should not exceed one hour, and work rest time should be 10 to 15 minutes before and after the next work. Legal regulations have not been reached yet, but static fatigue should be excluded. The more I instruct.

Generally, the manuscript reading table is arranged at a position beside the VDT screen or the keyboard and is out of the field of view of the operator when the key is pressed. Especially when inputting with reading glasses with stepless perspective, the vertical focal length of the lens is narrow, so to read the characters on the original, you have to shake your head greatly and look straight from the front. The burden will be even greater. Moreover, since the entire text of the one-page manuscript can be seen, when the eyes are moved to the keyboard or the VDT screen and the manuscript is returned to again, it may be difficult to find where the text to be subsequently hit is found. It can be said that it is completely in vain to enter the text that has already been entered, and it is only an obstacle when typing.

[0007]

[Problems to be solved by the device]

 The present invention provides a reading apparatus for sequentially recognizing manuscript characters having a simple structure for reducing techno-stress and improving efficiency, so that a large number of OA equipment users can use the reading apparatus on a daily basis. The purpose is to reduce the adverse physical and mental effects that are occurring.

[0008]

[Means for Solving the Problems]

 To this end, the reading device according to the present invention has two manually or electrically driven document feeding and take-up rolls arranged parallel to the longitudinal direction inside and at least one line of the document between the two rolls. It is characterized in that it is a box body having corresponding elongated openings in the front longitudinal direction, and can be arranged in the vicinity of the VDT of the OA equipment by a mounting means such as a pillar provided on the box body.

The reading device described above is a device separate from the OA device, and is attached to the OA device at the time of use, but for the sake of further convenience, it is permanently installed in or on the OA device. The reading device, which can be attached to the OA device, is arranged parallel to the longitudinal direction, and can take a use position separated from each other and a storage position in which at least some of them overlap each other. Two original feeding / winding rolls, drive means for selectively rotating one of the two rolls in an OA device, rotation for connecting each of the two rolls and the drive means A force transmission means, and a document cover provided in the vicinity of one of the two rolls at a use position and having an elongated opening corresponding to at least one line of the document between the two rolls. There is.

When the manual feeding / winding roll is manually operated, a sprocket wheel is provided at least at one end thereof, and if a sprocket chain is attached to these sprocket wheels, a knob outside the box connected to the roll end is provided. One of the rolls can be manually operated via the to feed the original from one roll to the other. In the case of electric drive, by connecting a sprocket chain between the electric drive device and a sprocket wheel provided at one end of each roll, or by using another drive transmission means connecting each roll and drive means. Then, one roll is selectively rotated (the two rolls rotate in opposite directions), and the original is wound from one roll to the other roll.

The reading device of the present invention can be basically placed as it is on the upper surface of the VDT of the laptop OA device or in an intermediate space between the VDT and the keyboard. In a device in which the means is not provided in the OA equipment (hereinafter, referred to as an attachable device), a column is provided at or near the longitudinal end of the box, and the free end of the column is perpendicular to the column axis. By making a flat plate and inserting this flat plate under the OA equipment, the writing device can be easily and stably arranged near the VDT.

Further, in a device in which the roll driving device is built in the OA equipment (hereinafter, referred to as a built-in device), the roll can be permanently mounted, for example, below the VDT in a state where the storage position is fixed. When using, the roll should be pulled out to the use position. The document cover can be attached immediately above the other roll in the storage position even if one roll is pulled out to the use position.

When the box containing the roll is attached to the column, or when the roll is attached to the OA device body, the roll can be positioned in the vertical direction or the horizontal direction by using a hinge with a ball joint or the like. It is also possible to construct the strut with two telescopic members so as to adjust the length of the strut.

[0014]

[Function of the device]

 With the above construction, the reading apparatus of the present invention makes it possible to see at least one line at the beginning of the original after winding one sheet of the original sheet around the original roll or the opening of the original sheet cover. It is possible to wind one end of the document on the other take-up roll, take up the line after the input is finished, and display the next new line in the opening. This winding may be performed manually or by using a driving means such as an electric drive, and the driving means can be provided in the box or the column or in the OA equipment main body.

If the relative position between the roll and the VDT is changed by using a ball joint or a hinge with a ball joint to attach the document holding portion of the reading device to the column or the main body of the OA device, horizontal writing can be performed. It can be used for both manuscripts and vertical manuscripts. Nesting the short side of the box for a mounted device and the short side of the document cover for an embedded device so that the box or document cover is composed of two members That is, it is possible to change the number of lines of the manuscript visible from there.

Hereinafter, the device of the present invention will be described in more detail with reference to the drawings showing two embodiments (attachable type and built-in type) of the reading device according to the present invention.

[0017]

【Example】

 As shown in FIGS. 1 and 2, the mountable reading device according to the present invention has a box 1 for storing a document as a main part, and in the illustrated embodiment, the box 1 has a column 2. The box body 1 is arranged immediately below the VDT 3 of a word processor or personal computer having a laptop type VDT.

The box body 1 has a pay-out roll 4 and a take-up roll 5 which are arranged in parallel in the longitudinal direction at intervals corresponding to several lines of the document inside, and at both ends thereof, respectively. .. are mounted, and the sprocket wheels of rolls 4 and 5 are connected by a sprocket chain 7 (in FIG. 2, only the left sprocket wheel and sprocket chain are appear). A knob 8 is connected to the roll 4 and a knob 9 is connected to the roll 5 so as to project outside the box body 1.

The plate forming the front of the box body 1 can be opened and closed in the left-right direction or the up-down direction by a hinge, and the opening 10 corresponding to the number of lines of the document stored in the box body 1 is provided. , Provided in the longitudinal direction. The number of lines does not have to be specified particularly strictly, but about 3 lines is preferable in consideration of the winding frequency and the ease of confirming the location of the character to be input.

The support column 2 for supporting the box body 1 is attached via a ball joint 11 to an appropriate position on the back surface of the box body 1 (in FIG. 2, in the vicinity of the right end of the axis passing through the center of the back surface in the longitudinal direction). Be done. Therefore, if the box body 1 is rotated 90 ° in the direction of the arrow, it can be used for a vertically written original. A plate 12 is attached to the lower end of the pillar 2 at a right angle to the pillar axis (bent at a right angle when the pillar 2 is made of a plate material), and is inserted under the keyboard portion of the OA device. It is possible to easily and stably dispose the box body 1 supported by the column 2 in a cantilever state in the vicinity of the VDT 3. Also, the column 2 can be composed of two telescopic members that are slidable with respect to each other so that the length thereof can be adjusted.

Next, the use of this reading device will be described. First, the front cover of the box 1 is opened, and one or a plurality of stacked originals are set on both rolls 4 and 5 (when the number of originals is large, the originals are set several times). In order to set the original accurately, the rolls 4 and 5 may be provided with longitudinal slots into which both edges of the original (upper and lower edges in the case of a horizontal original) are inserted. The original is tensioned between the rolls 4 and 5 by closing the lid and selectively turning one of the knobs 8 and 9 as appropriate, and the first to third rows (opening 10 Corresponds to 3 lines) so that it can be seen through the opening 10. The rolls 4 or 5 can be electrically driven by a battery or an external power source arranged in or near the box body 1.

Next, the flat plate 12 of the support column 2 is inserted and fixed under the keyboard portion of the OA device, and the box body 1 is placed between the VDT 3 and the keyboard portion (immediately below the VDT 3) as shown in FIG. Preparation is completed by arranging in the space.

Since the VDT 3, the opening 10 of the box body 1 and the keyboard portion are all arranged in front of the operator of the OA device, the operation of inputting a document becomes extremely easy. By rotating the knob 9 around the line of the document that has been input and winding it on the roll 5, and by feeding the new line to be input from the roll 4 to the opening 10, the operator can see only a limited part of the document. , No more misunderstanding what you should get. After inputting one original, open the front cover and set a new original, or if multiple originals have been set, remove only the input original and repeat the above operation.

Next, the built-in reading device according to the present invention will be described. The principle structure is almost the same as the mounting type, but it is as compact as possible in order to incorporate the roll drive means in the OA equipment and to store the original setting part of the reading device if possible on the OA equipment. It is designed to have a different structure.

FIG. 3 is a layout view of main components in one embodiment of the built-in reading device according to the present invention incorporated in a laptop OA device. The document cover panel 21, the roll driving device 22, and the document are shown in FIG. A rotation force transmission device 24 for transmitting the rotational force of the feeding / winding device 23, the roll driving device 22 to the document feeding / winding device, and a control switch 25 for the roll driving device are shown.

The cover panel 21, which is a document cover, corresponds to the front cover of the box 1 in the case of the attachment type, and like the box 1, the openings corresponding to several lines of the document are in the longitudinal direction. The left and right short sides in FIG. 3 have a slidable telescopic structure, so that the size of the opening can be adjusted and the cover panel 21 can be extended to an appropriate lower position when used. .. The cover panel 21 is attached to the OA device main body through a ball joint at the upper right end, and the upper left end is detachably locked with a snap. Therefore, in the case of a vertically written document, the snap can be removed and the cover panel 21 can be rotated 90 ° in the direction of the arrow. If the VDT is hidden by a cover panel, you can use a double-joint ball joint and separate it to the right side of the OA equipment body.

FIG. 4 is an exploded view showing configurations and operations of the roll driving device 22, the document feeding / winding device 23, and the rotational force transmitting device 24. The roll driving device 22 includes a micromotor 31 with a reduction gear, bevel gears 32, 32 ', and two one-way clutch bearings 33 (may be a ratchet gear). The forward and reverse rotations of the micromotor 31 are bevel gears. 32 to the bevel gear 32 ', and is transmitted to one of the rotational force transmission devices 24, which will be described later, via one of the one-way clutch bearings 33.

In FIG. 3, the document feeding / winding roll device 23 housed in the keyboard panel of the laptop word processor is composed of two plate-like sprolls 34A and 34B so as not to take up a storage space. At times, the two plate-like sprawls 34A and 34B overlap each other, and when in use, the guide pins 36 fixing the hinge arms 35 of the respective sprawl plates 34 are pulled out, so that both sprawl plates 34 are deployed to the use position (Fig. 5-1 and FIG. 5-2). One longitudinal end of one of the sprawl plates (in FIG. 5, the sprawl plate 34B located below when it is stored) is attached to the keyboard portion by a ball joint 38 via a telescopic strut 37.

The rotational force transmission device 24 for rotating one of the sprawl plates is a flexible shaft 40 that connects the one-way clutch bearing 33 of the roll drive device 22 and one end of the shaft 39 of the sprawl plate 34. The forward or reverse rotation of the micromotor 31 can be selectively transmitted to one of the sprawl plates 34 (34A or 34B) to wind or rewind the original document.

In the case of the built-in type, (1) only the roll drive device is built in the OA equipment, (2) in addition to the roll drive device, the rotational force transmission device is also housed in the OA equipment like an electric cord, (3) As shown in FIG. 3, three kinds of modes are conceivable, in which the feeding / winding device is also fixed on the OA device. Also in the case of (3), a mode in which the rotational force transmission device is always connected to the feeding / winding device, and a rotational force transmission device housed in the OA device is connected to the feeding / winding device when in use There is also a mode to do so, and various modified modes can be taken as necessary.

Next, the use of this reading device will be described. First, the guide pin 36 of the document feeding / winding device 23 is pulled out, and the two sprawl plates 34A and 34B are brought to the arrangement positions when in use by unfolding the hinge arm 35. After connecting the flexible shaft 40 of the torque transmission device 24 to one end of the shaft 39 of each sprawl plate 34, the original is set on both sprawl plates 34A and 34B. In this case, it is preferable that slots are provided in the longitudinal direction of each sprawl plate, or that sprinkling plates are provided so that both edges of the document can be easily suppressed. Then, the control switch 25 is operated to rotate the micromotor 31 in the reverse direction, and the sproll 34B is rotated in the reverse direction so that the document is tensioned between the spraws so that the beginning of the document can be seen between the sprolls. When the cover panel 21 is pulled down on the thus prepared document, the first few lines of the document can be seen through the opening. The manuscript that has been input is wound around the sprawl 34A by rotating the micromotor 31 in the forward direction, and a new part of the manuscript becomes visible through the opening of the cover panel 21, but the sprawl 34 is a plate. Since it is a shape, it cannot be wound at a constant speed, so it is convenient to wind multiple lines by rotating the sprawl plate 180 °. At this time, the guide pins 36 play a role of preventing the original paper surface from wavy. Needless to say, when one sprawl plate (34A, for example) is driven, the other sprawl plate (34B) is in a play state.

[0032]

[Effect of the device]

 The book-reading device of the present invention has the above-mentioned configuration, and by performing the operation, the following remarkable effects can be obtained.

Since only the limited part of the document to be input can be sequentially viewed, the input part and the uninput part are not erroneously recognized, or very few.

Since the VDT of the OA equipment, the keyboard section, and the document reading apparatus can all be arranged in front of the operator, it is possible to input while facing the front without moving the eyes or neck left or right, and the techno It greatly reduces stress and also significantly improves work efficiency.

As described above, by using the reading device of the present invention, the OA device operator such as a word processor and a personal computer can be freed from the VDT syndrome including various ocular symptoms that have been conventionally troubled. Since it is possible to prevent mistakes and input errors, the effect is extremely large.
