BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic binder having a plurality of handwriting-enabled display units.

[0002]

2. Description of the Related Art Conventionally, a so-called binder is often a detachable binder main body in which a plurality of papers are detachably attached to a binding portion provided inside a back portion of the binder main body. Can be seen. This item is used by handwriting on paper with or without being attached to the binder, and when the contents are to be preserved, they are bound to the binder body.

[0003]

In recent years, computers and the Internet, which are information processing devices, have become widespread, and various kinds of information are often handled as electronic data.

However, in the case of a binder provided with paper as described above, the information handled as electronic data must be written by hand by hand or once output on a print sheet, and then bound. Furthermore, once written, the contents are not often reused after being erased with an eraser, etc., and are often thrown away as they are no longer needed, so the number of sheets increases with time, and There will be a need to increase the number of binders.

In addition, from the viewpoint of environmental protection and cost reduction, it is now proposed that paper resources be saved, in other words, paperless is required, and it is desired to reduce the number of papers used as much as possible. There is also the current situation.

However, the act of drawing letters and pictures on paper by hand has been an extremely excellent characteristic that humans have come to know for the purpose of transmitting information since ancient times. Even in recent years when the act of recording information in a computer using such a device has become standard, it does not change.

In view of the above situation, the present invention provides a new binder that can be handwritten and can handle the handwritten content as electronic data.

[0008]

That is, the present invention is to provide a plurality of sheet-like display portions that can be continuously displayed while holding the display contents, and an input portion that allows handwriting input from the outside on the display portions. And a binder main body that has a control unit that performs display control for displaying an image based on an input trajectory during handwriting input by the input unit and that can detachably hold a plurality of display units in a bundled state. An input locus discriminating means configured to be provided and reading an input locus at the time of handwriting input in the input unit;
At least an input trajectory converting means for converting the input trajectory read by the input trajectory determining means into data, and an input trajectory transmitting means for transmitting the input trajectory signal converted into the data by the input trajectory converting means to the binder body are provided. The display unit is provided with a display unit for displaying an image, a written unit capable of handwriting input by the input unit, and a connecting unit for connecting to the control unit so as to be capable of transmitting signals, and the control unit is provided with an input trajectory signal. An input trajectory signal receiving means for receiving the input trajectory signal transmitted by the transmitting means is provided, and a display control signal is transmitted based on the input trajectory signal received by the input trajectory signal receiving means to display a handwritten image corresponding to the input trajectory. It is an electronic binder provided with display control means for performing processing for displaying on the display unit.

Here, a technology of a thin display called electronic paper, which has been developed in recent years from the viewpoint of displaying electronic information, can be applied to the display section. This electronic paper has a thickness of 0. It can be bent as thin as a few mm like paper and can be rewritten. Also, unlike so-called rewritable paper,
Many papers have been developed in which, after the image is once displayed, the paper itself can hold and display the image-displayed state even in a non-powered state. Regarding such electronic paper, for example, a microcapsule electrophoresis method represented by E-Ink (US E-Ink Co., Ltd.) for electrophoresing charged particles, Gyri for rotating charged particles at high speed.
Development of various methods such as twist ball method represented by con (Xerox Inc. of the United States, Gyricon Media Inc.), liquid crystal and organic photoconductor composite film method by ion flow writing, toner display method, etc. has been active. In addition, electronic paper using a liquid crystal and an organic EL element and electronic paper that displays an image by applying light energy or electromagnetic waves are being developed.

The "input unit capable of handwriting input from the outside" means that information can be input to the display unit by an input operation of handwriting, and even if the input locus does not physically remain. Good. Then, the input locus is converted into data in such an input unit by analyzing the information of the surface of the display unit traced by, for example, an optically read pen tip and the movement of the pen tip, and the data is input to the Bluetooth.
It is also possible to apply a mode in which the information is directly or indirectly transmitted to the control unit by the th or the like (Israel, GOU
Lite company revised Virtual Pen (V Pe

However, for example, the position information providing pattern is imaged tens to hundreds of times continuously in one second.

The input locus conversion means 23 converts the input locus read by the input locus discriminating means 22 into digital data by digitizing it by the processor 2c and further digitizing it. Further, the input locus data transmission means 24 transmits the input locus data converted into digital data from the communication interface 2e to the control unit 3.

In the present embodiment, the control unit 3 is attached to the back portion 4a of the binder body 4 as shown in the drawing, and receives the input trajectory data received from the input pen 2 and the external personal computer P.

The display control signal is generated according to the respective data, and the display control signal is transmitted to the display driving means 13 in the display unit 1. Then, when the display driving means 13 receives the display control signal, a voltage is applied to the display substrate 1c to form a predetermined electric field pattern as described above, whereby a display is made on the display means 14. It should be noted that the external image data may be divided into a plurality of display units 1 and a signal for controlling display may be transmitted.

The input locus data receiving means 32 receives the input locus data generated by the input pen 2 by handwriting input from the input locus data transmitting means 23, and the input locus data received here is at least temporarily.

The external image data receiving means 33 receives external image data generated and transmitted by an external information processing device such as a personal computer P through the communication interface 3d, and the external image data received here is at least temporarily. Be remembered. Then, the stored external image data is transmitted to the display control means 31.

The displayed data storage means 34 stores the displayed data based on the image displayed on the display unit 1 by the display control means 31 into file data.
The data format of this file data includes various types such as a general image data format and a format depending on a specific application, and is not particularly limited, and a plurality of data formats may be selectable. In particular, the input trajectory data can also be stored as data along the time axis when inputting with the input pen 4. Further, when the past display data is displayed again on the display unit 2, the corresponding file data read through the operation of the operation unit is sent to the display control means 31. Further, when the displayed image data displayed based on the input trajectory data and the displayed image data displayed based on the external image data received from the external personal computer P are simultaneously displayed on the display unit 2, they are displayed. It can be integrated and stored as one file data, or can be separately stored. Further, the displayed data accumulating means 34 may accumulate the displayed data based on the image displayed on the display unit 1 for each display, or based on the specific image designated by the user. You may make it accumulate | store only displayed data.

It can also be configured to exchange data. Next, a method of using the electronic binder A of this embodiment will be described.

First, the case where the input pen 2 overwrites the display unit 1 with the display unit side connection terminal 1d of the display unit 1 connected to the control unit side connection terminal 3d will be described.
At this time, as shown in FIG. 2, when the handwritten image is displayed by overwriting it on the display unit 1 in which the external image is already displayed, when the handwritten image is displayed on the display unit 1 in a blank state. Is also the same. The operation in this case is as shown in FIG.
As shown in the flow chart in FIG.
When the pen pressure applied to the pen tip 2a of the input pen 2 is detected (step S1) by drawing by touching the surface of the pen and tracing (step S1), the CMOS camera 2b operates to capture the position information providing pattern (step S1). S2). The imaging of the position information provision pattern is performed several tens to 100 times per second as described above. Then, by analyzing the imaged position information providing pattern, the locus of the position information providing pattern moved by the pen tip 2a, that is, the input locus is digitized and converted into data (step S3), and input locus data is generated (step S4). The input trajectory data is transmitted to the control unit 3 (step S5). On the other hand, as shown in the flow chart of FIG. 10, when the input locus data is received by the control unit 3 (step S11), the input locus data is temporarily stored (step S12) and corresponds to the stored input locus data. A display control signal is generated (step S13). Further, the control unit 3 transmits the display control signal to the display unit 2 (step S14). Also,
The control unit 3 controls the display unit 1 based on the external image data.
Displayed data based on the image displayed in step S15 is accumulated (step S15). It should be noted that, at the time of storing this displayed data, when both images are simultaneously displayed on the display unit 1, such as when the display unit 1 displaying the external image is overwritten by handwriting, the external image data Displayed data based on handwritten input trajectory data may be integrated into a file and stored. Further, in particular, the input trajectory data can be accumulated along the time axis at the time of handwriting input.
Furthermore, as shown in the flowchart of FIG. 11, when the display unit 1 receives this display control signal (step S21),
The electric field pattern corresponding to the display control signal is displayed on the display substrate 2.
Input locus applied to a1 (step 22) and handwritten using the handwriting image, that is, the input pen 2 (memo in this example)
The same image as is displayed at the position corresponding to the handwritten portion (step S23). Here, it is preferable that the process from the handwritten drawing using the input pen 4 to the display of the input locus on the display unit 1 be performed as soon as possible even if there is a slight time lag. This is because the handwritten drawing using the input pen 2 is not physically written on the display unit 1, but the position information providing pattern is read by the CMOS camera 2b by tracing the surface of the display unit 1. If not immediately reflected, it is difficult for the user to intuitively understand the drawn contents, and the thought is interrupted.

As shown in FIG. 7, when an image received from an external personal computer P or the like is displayed on the display unit 1 (which may be one or plural), a flow chart shown in FIG. When the controller 3 receives external image data (for example, a calendar in the illustrated example) from the personal computer P (step S31), the external image data is temporarily stored (step S32), and the stored external image data is handled. To generate a display control signal (step S3)

(Step S34). Further, in the control unit 3,
Displayed data based on the image displayed on the display unit 1 based on the external image data is accumulated (step S5).
On the other hand, as shown in the flow chart of FIG.
When this display control signal is received (step S41), the electric field pattern corresponding to the display control signal is displayed on the display substrate 2a.
1 (step S42), and the same image as the external image, that is, the image (calendar in this example) displayed on the display Pd of the personal computer P is displayed (step S4).
3). The external image may be selected to be displayed on the entire display unit 11 or a part of the display unit 11. In this case, the external images may be displayed part by part on the display means 11 of the plurality of display units 1. Further, one external image may be displayed on the display means 11 of the plurality of display units 1.

Further, the input trajectory data corresponding to the handwritten image currently displayed on the display unit 2, the external image data corresponding to the external image, and the past-displayed data stored in the image-displayed data storage means 34 are displayed on the display unit 2. When outputting the displayed data that has been displayed to the external personal computer P, as shown in the flowchart of FIG. 14, a small display or an operation unit provided in the control unit 3 is used to display control the corresponding data. The data is read from the means 31 or the displayed data storage means 34 (step S51) and transmitted via the output means 37 (step S52). In particular, when reading out the displayed data, it is convenient to display a list or preview of the file data stored on the display or the like provided in the control unit 3 so that the corresponding one can be selected from them. Is.
