DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to FIGS. FIG. 1 is a diagram illustrating a coordinate input device according to the first embodiment. The coordinate input device includes a coordinate detection unit 1 and a storage device 2
, An input pen 3, a thin button battery 5 as a power source, and a housing 4 holding the above components. Information written by the input pen 3 is detected as a coordinate value by the coordinate detection unit 1, and the detected coordinate values are sequentially recorded in the storage device 2. The coordinate value information is recorded in a format that can be easily read by a personal computer or the like. For example, information entered in a schedule book can be handled on the personal computer. The housing 4 is thinner than a predetermined amount in the z direction, and has a shape like an underlay that can be inserted between sheets bound in a system organizer or a loose-leaf file. Therefore, the handwritten information can be digitized by the coordinate input device without taking out the paper from the binder.

When the input pen (instruction means) 3 designates a flat or substantially flat surface, the coordinate detecting unit 1 detects the coordinates of the flat or substantially flat surface indicated by the input pen 3 on the surface. The storage device 2 stores, in a readable format, one or more coordinate values detected by the coordinate detecting unit 1 having a plate-like shape with a thickness of a predetermined amount or less. As described above, in the coordinate input device according to the present embodiment, the input pen 3 capable of writing characters and figures on a plane as a paper as usual and capable of indicating a coordinate position, and A casing 4 having a plate-like shape with a thickness of 1, a coordinate detecting unit 1 for detecting a coordinate value specified by the input pen 3, a storage device 2 for storing the coordinate value detected by the coordinate detecting unit 1, and a thin type. It has a power supply device that uses the button battery 5 as a power source. By pulling this coordinate input device like an underlay under a sheet, it can be sandwiched between a plurality of sheets bound in a system notebook or a file notebook. With the paper bound to the binder, the information written on the paper can be digitized.

FIG. 2 is a diagram showing a first modification of the coordinate input device according to the first embodiment. The coordinate input device according to the modified example as shown in FIG. 2 includes an input pen 3 that can write characters and drawings on a sheet as usual and can indicate a coordinate position, and a plate-like shape having a thickness of a predetermined amount or less. , A coordinate detecting unit 1 for detecting a coordinate value specified by the input pen 3, a storage medium 2a for storing the coordinate value detected by the coordinate detecting unit 1, and a thin button battery 5 as a power source. And a detachable unit (removing device) 2b for detaching and attaching the storage medium 2a.

Although the basic configuration is the same as that of the coordinate input device of FIG. 1, the storage device 2 of FIG.
Is different from the coordinate input device of FIG. The storage medium 2a can be detached by detaching means 2b. This facilitates data exchange with a personal computer or the like. Examples of the storage medium 2a include smart media. Since the smart media is thin, it does not affect the thinness of the coordinate input device according to the present embodiment. In addition, if a plurality of smart media are prepared, the storage capacity is not limited, and necessary information can be carried. In the coordinate input device of the present embodiment, the limit of the amount of information that can be stored can be eliminated, and the handling of information and portability can be improved.

FIG. 3 is a diagram showing an example of the size of the coordinate input device. The coordinate input device 6 of the present embodiment is inserted between sheets bound in a system organizer or loose-leaf file, and the information written on the sheet is detected by the coordinate detecting unit 1. Therefore, it is desirable that the size of the coordinate input device does not exceed the size of the system organizer or loose-leaf file. Therefore, in this embodiment, as an example,
As shown in FIG. 3, when the A-row 4-size paper 7 specified by JIS is placed in front of the coordinate input device 6, the size of the coordinate input device 6 should be up to +10 mm around the A-row 4-size paper 7. This value is a value that can be set because a commercially available binder has at least a size greater than this value for the paper to be bound. Therefore, the area of the xy plane of the coordinate input device 6 is 120% or less of the A-row 4-size paper.

In the coordinate input device according to the present embodiment, a projection area in a normal direction of a coordinate detection surface which receives an instruction from an input pen (instruction means) 3 of a casing 4 constituting a coordinate detection section (coordinate detection means) 1. However, the projected area does not exceed 120% of the projected area of any of the A-line type, B-line type, legal, letter, and bible paper sizes specified by JIS. Further, in the coordinate input device of the present embodiment, the size of the housing 4 is JIS.
120% of the specified paper size, such as the prescribed A-row or B-row
Is not exceeded. As described above, in the coordinate input device according to the present embodiment, the size of the housing 4 or the coordinate detection surface of the coordinate input device is set to the A-line system, the B-line system, or any of the legal, letter, and bible papers specified by JIS. Since the size does not exceed 120% of the projected area, the coordinate input device main body does not protrude out of the binder when it is placed in the binder, so that deterioration of portability can be prevented.

FIG. 4 shows an example of a binder. A commercially available ordinary binder 9 binds the paper 14 by passing a ring 10 of the binder 9 through a binding hole 8 formed in the paper 14 and fixing the ring 10 to the binder 9. If the coordinate input device according to the present embodiment is merely inserted into such a binder 9, the coordinate input device and the binder 9 are separated, and the coordinate input device may be lost.
Further, the positional relationship between the present coordinate input device and the paper 14 may be significantly shifted during the coordinate detection, and the coordinate value may not be accurately detected. Therefore, the present coordinate input device and the binder 9
It is desirable to bind Therefore, A
A bundling unit capable of bundling a plurality of sheets of a predetermined size of any one of a row system, a B-row system, legal, letter, and bible includes a coordinate input device which is a main body of the coordinate detection unit (coordinate detection unit) 1 and a predetermined It is provided with a holding means such as a binding hole 8 and a ring 10 capable of binding paper of the same size at the same time. In the coordinate input device of the present embodiment, the coordinate input device and the binder are integrated, and the holding device capable of simultaneously binding the coordinate input device and a sheet of a predetermined size is provided. The misalignment can be prevented.

FIG. 5 is a diagram showing a second modification of the coordinate input device according to the first embodiment. As shown in FIG. 5, the coordinate input device according to the second modification is a hole formed in one or more coordinate detectors (coordinate detectors) at a predetermined interval corresponding to a predetermined sheet. The coordinate input device 6 is provided with a binding hole on the upper surface, which is the coordinate detecting unit 1, so that the binding unit can be bound to a ring type binder. The basic configuration is the same as that of FIG. 1, but a binding hole 8 that can be bound to a binder 9 as shown in FIG. FIG. 4 and FIG. 5 are views showing a 6-hole type widely used in a system organizer of A-row 5-size as an example. By passing the ring 10 of FIG. 4 through the binding hole 8 and simultaneously binding the sheet 14 and the coordinate input device 6, the binder 9 and the coordinate input device 6 are integrated, and
4 can be prevented from being largely displaced from the coordinate input device 6. Furthermore, by adopting a configuration that can be integrated with paper as in the coordinate input device of the present embodiment, it is possible to enhance the versatility of the coordinate input device.

FIG. 6 is a diagram showing a third modification of the coordinate input device according to the first embodiment. The binder 9 as shown in FIG. 4 has a structure in which the paper 14 is attached or detached by opening and closing the ring 10. In the coordinate input device 6 provided with the binding hole 8 as shown in FIG. 5, the ring 10 must be similarly attached and detached by opening and closing. Therefore, a cutout portion 8a is provided in the binding hole 8 as shown in FIG. It is desirable that the material of the notch 8a is a shape memory material such as soft plastic that easily bends and returns to the original shape. By providing such a notch 8a, the coordinate input device 6 can be attached to and detached from the ring 10 without opening and closing the ring 10. As described above, the coordinate input device according to the third modification includes the cutout portion that can be removed without releasing the ring 10 as the holding unit. The cutouts are formed in the diameter direction from the center of one or more holes installed on the coordinate detection unit (coordinate detection means) 1 to the circumference. Thereby, the coordinate input device according to the present embodiment can be detached without opening and closing the ring 10 which is the binding portion of the binder 9.

As described above, the coordinate input device 6 is a device for digitizing and recording information written on the paper 14 bound to the binder 9 such as a system notebook. It is necessary to prevent a situation in which it is not possible to know which sheet (page) each coordinate value has been written on by merely recording coordinate values sequentially, so that information cannot be reused. Therefore, it is desirable to group the coordinate groups detected for each sheet of paper 14. As a method, there is a method of adding a tag indicating the information written on each paper to each coordinate value and recording it, and plotting the value at the position where coordinates were detected using one sheet as a single binary image There is a way to go. As described above, the storage device 2 of the coordinate input device 6 may record the coordinate group detected by the coordinate detection unit 1 in page units, or a storage mechanism different from the storage device 2 may be provided. It may be.

FIG. 7 is a diagram showing an example when a coordinate input device is inserted into a binder. When inserting the coordinate input device 6 into the binder 9, two right and left sides as shown in FIG. 7 may be used. That is, there is a case where the coordinate input device 6 is inserted into the left side of the spread of the binder 9 and a case where the coordinate input device 6 is inserted into the right side. When the coordinate input device 6 has the coordinate detection unit 1 only on one side (front), as shown in FIG.
The direction of the y coordinate will be reversed. When the recorded coordinate values are converted into an image using a personal computer, etc.,
An image that is rotated 180 ° on the left and right sides of the spread is obtained. It is also possible to rotate the personal computer 180 ° again, but this increases the burden on the user. As one of means for solving this, a method is conceivable in which the coordinate detection units 1 are provided on both surfaces (front and back) of the coordinate input device 6, respectively. In this way, by using the coordinate detection unit 1 on the front side on the double-page spread and the back side on the double-page spread, the direction of the coordinates can always be kept constant.

As described above, in the coordinate input device according to the present embodiment, the coordinate detecting section (coordinate detecting means) of the coordinate input device 6.
1 is provided on both sides of a flat or substantially flat surface, or provided on both sides (front and back) of the plate-shaped casing 4 so that the coordinate detection unit 1 detects even when the coordinate input device is installed on the spread left and right. The coordinate direction of the input information can be always constant. Further, in the coordinate input device of the present embodiment, it is possible to detect the coordinates irrespective of the spread of the sheets bound to the binder.

Next, by providing the coordinate detecting section 1 on both sides of the coordinate input device 6, the coordinate direction can be kept constant, and the coordinate detection can be performed regardless of the spread of the sheets bound to the binder. Another embodiment of another solution that can be described will be described. FIG. 8 is a diagram illustrating a coordinate input device according to the second embodiment. FIG. 9 is a diagram illustrating an example in which the coordinate input device according to the second embodiment is inserted in a double-page spread. FIG. 10 is a diagram showing details of a binding hole of the coordinate input device. FIG. 11 is a diagram showing a coordinate input device having a binding hole for detecting a spread left and right.

By further providing a means for detecting the coordinate direction of the coordinate input device 6 or a means for switching the coordinate direction, the user can operate the coordinate input device so as to satisfy the conditions determined according to the right and left spreads. By attaching the sheet, coordinate detection can be performed regardless of the spread of the sheets bound to the binder. If the condition is satisfied, it is possible to identify which direction is on the sheet, and record the coordinate value by adding information on the coordinate direction when recording in the storage device 2. By providing the coordinate direction detecting means for recognizing the direction in which the coordinate detection unit 1 is bound, that is, the binder is provided with the coordinate direction detecting means for recognizing the direction in which the coordinate input device 6 is bound, the page for which the information is to be obtained is displayed on the spread of the binder. By detecting whether the page is a left page or a right page, the direction of the coordinate input can be determined.

One method for detecting the coordinate direction is to increase the number of binding holes 8 as shown in FIG. FIG. 8 shows that a total of eight holes are provided by adding two holes to the binding hole 8 of the six-hole type. When the ring 10 of the 6-hole binder 9 is passed through the binding hole 8, for example, as shown in FIG. When the ring is passed through the binding hole 8 in the binder 9 with the spread left and right, the binding hole 8 that passes through the binding right 8 differs from the binding hole 8 that passes through the binding left as shown in FIG. 9. Therefore, a protruding switch 19 as shown in FIG. 10 is provided in the binding hole 8 through which the ring 10 passes through only one of the left and right sides. The projection switch 19 is configured to be turned on by passing the ring 10 through. The binding hole 8 having such a protruding switch 19 is provided in FIG.
As described above, if the coordinate input device 6 is provided with the binding hole 8b for detecting the spread right and the binding hole 8c for detecting the spread left, the coordinate direction can be automatically detected only by the user satisfying the condition 1. .

As described above, the coordinate input device according to the present embodiment has, as the coordinate direction detecting means, more holes than the number of holes necessary for binding with the binder, and the position of the hole to be passed at the time of binding is different depending on the position of the hole to be passed. By providing the coordinate direction automatic detection means for detecting the binding direction, the coordinate direction can be automatically detected.

Since the detected coordinate group is desirably recorded for each page, it is necessary to detect the timing of updating the page. Therefore, the page is updated when the projection switch 19 as shown in FIG. 10 is turned on or when the projection switch 19 is turned off. This allows the page to be automatically updated each time the user changes a new page. Since the coordinate direction automatic detection means has a projection switch inside the binding hole and presses or releases the projection switch to further provide a page updating means for updating a page recorded in the storage means, the storage device Can be automatically stored every time a page is updated. Also, the page update means updates the page recorded in the storage means by pressing or releasing the projection switch arranged inside the hole,
Acquisition information can be automatically updated in a storage medium.

FIG. 12 is a diagram showing a coordinate input device according to the third embodiment. FIG. 13 is a diagram illustrating the coordinate input device when the changeover switch is moved. The coordinate input device according to the third embodiment has a changeover switch as a coordinate direction detecting means, and moves the changeover switch to a position corresponding to the binding direction to detect the coordinate direction switching means. Have. As one method of detecting the coordinate direction, a changeover switch 11a as shown in FIG.
Is provided on the coordinate input device 6. The changeover switch 11a is about the size of a tag sticker attached to the paper 14 bound to the binder 9, can move along the slide groove 11b, and detects the coordinate direction when reaching the end of the slide groove 11b. It is. The switch 11a is located at the center of the coordinate input device 6 in the y direction when not in use. In order to detect the double-page spread, for example, the changeover switch 11a is moved to the upper end as the condition 2 as shown in FIG. Since the position where the changeover switch 11a is moved is different between the case of the double-page spread and the case of the double-page spread, the left and right of the double-page spread can be detected. The user can switch the coordinate direction by moving the changeover switch 11a according to the condition 2.

Further, the coordinate input device is provided with a page updating means for updating the page when the changeover switch is moved. In order to record the detected coordinate group for each page, the timing of updating the page is detected. As one method of timing detection, a method of updating the page when the changeover switch 11a is moved to a position corresponding to the left and right sides of the spread, or when returning from the moved position to the unused position is considered. The user can automatically update the page at the same time as switching the coordinate direction.

The coordinate input device 6 according to the present embodiment is a device that is inserted between sheets bound in a system organizer or the like, and detects and records information written on the sheet as coordinate values. Therefore, the coordinate input device 6 must have a thickness that can be bound at the same time as the paper, a thickness that does not hinder the turning of the paper, and a thickness that does not hinder writing on the paper. In general, the thickness of plain paper used in a system organizer is about 0.9 mm. The diameter of the ring of the system organizer is at least about 10 mm. As described above, in order to bind at least one sheet of plain paper and the coordinate input device 6 to a ring having a minimum diameter of 10 mm, the thickness of the coordinate input device 6 must be 8 mm or less.

Therefore, the thickness of the coordinate detecting section 1 is 8 mm or less which does not hinder opening / closing of the sheet and writing on the sheet even if the coordinate detecting section (coordinate detecting means) 1 is bound together with the dozens of ordinary sheets by the holding means. By doing so, the thickness of the coordinate input device becomes sufficiently thin, so that it does not hinder opening and closing of the binder and writing to paper.

FIG. 14 is a diagram showing the template 12. For example, a template 12 as shown in FIG. 14 is registered in advance. The template 12 is a one-week schedule table, and the position of “2000”, the position of “July”, and the position of each date are surrounded by a line. Each box is set as one group frame 13, and information on which group the group belongs to is added and the coordinate value is recorded. In this way, the information taken into the personal computer or the like can be easily separated according to the date, and if the user freely creates and registers the template 12, arbitrary information can be easily created for the user. Can be carved.

As described above, the coordinate input device 6 can take the recorded coordinate values into a personal computer or the like and reuse the information. As described above, the recorded information is grouped on a page basis, but the efficiency of reuse can be improved by further finely grouping the information. In the coordinate input device according to the present embodiment, the coordinate detection unit 1 is determined by the template paper in a format that can be registered in advance and that is arranged on the coordinate detection unit (coordinate detection unit) 1 and the position written on the template paper. And a coordinate group grouping means for grouping the coordinate groups detected in step (1), so that the ease of handling when the stored information is reused can be improved.

According to the first aspect of the present invention, the storage means comprises:
Since it is detachable from the coordinate input device, a plurality of storage media can be prepared, the limit on the amount of information that can be stored can be eliminated, and the ease of handling and portability of information can be improved. According to the second aspect of the present invention, when there are a plurality of predetermined sheets, the storage means stores, for each page, the coordinates of the instruction-input image information detected by the coordinate detection means, so that the storage information is managed and reused. The ease of handling at the time can be improved. According to the third aspect of the present invention, since the coordinate detecting means detects the direction of the coordinates of the image information designated by the input instructing means in accordance with the detection result by the detecting means, it automatically detects the left and right sides of the binder spread, The coordinate direction can be automatically determined. According to the fourth aspect of the present invention, the detecting means detects whether the coordinate input device is installed under the left or right page based on the vertical movement position of the movement switching means. The direction can be switched. Claim 5
