Abstract

PURPOSE:To make one pen execute many functions by detecting the direction of an input pen, and outputting the detected content and specified coordinate data. CONSTITUTION:When a stylus pen unit 2 is using a S pole tip on a digitizer device 1, the center of the N poles of magnetic plates 6 are oriented toward input point 5 of the pen tip, so slits 7' are present at positions where light receptor elements 9 can receive lights from light emitting elements 8. When using N pole pen tip 4, the slits 7' are present at positions where lights from light emitting elements 8 do not enter light receptor elements 9. Accordingly, pen tips 3 and 4 can be assigned to a writing mode and a deletion mode, and either one of these modes can be securely known by the output from light receptor elements 9.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a coordinate input device and an electronic device using the same.

[Conventional technology]

Conventionally, as shown in FIG. 7, this type of device includes a digitizer device such as a resistive film type digitizer device for inputting data and a display device integrated therewith. By performing input operations with a stylus pen, performing various arithmetic processing to determine the coordinate position of the specified point, and reflecting the processing based on that on the display device, users who are not familiar with special input devices such as keyboard devices can It is constructed so that the work can be done easily and reliably. Therefore, it is necessary to make it possible to use a stylus pen or a book to input many of the function keys that exist in conventional keyboard devices. Therefore, the operating environment is designed so that multiple input modes can be easily switched as shown in Figure 7 by performing the same operation with a stylus pen or a similar operation. As shown in Figure 8, in order to facilitate the user's mode identification, multiple stylus pen devices are provided to support several types of modes, and a switch is provided in the pen holder to detect the pen currently in use. , it is designed to determine which pen is currently being operated.

[Problem to be solved by the invention]

However, in configurations such as the above-mentioned conventional example, there is a tendency for electronic devices to have more advanced functions, and as a result, input modes using a stylus pen also tend to increase. Therefore, various functions have to be handled by dividing them into menus, but the menu selection means has become multi-branched and multi-layered as shown in FIG. Therefore, although the input operation performed by the user using a stylus pen is simple, the number of input operations and the procedure have become complicated, and there is a problem in that it is easy to make mistakes in the operation. Also, in the case of the configuration shown in Figure 8, it is necessary to put the pen back into the pen holder and then pick it up again, and if a different pen is inserted into the pen holder, a different mode may be selected. There was a drawback. The present invention has been made in view of such prior art, and includes:
The present invention aims to provide a coordinate input device that performs more functions than a book input pen, and an electronic device using the device.

[Means to solve the problem]

In order to solve this problem, for example, the coordinate input device of the present invention has the configuration shown below. That is, in a coordinate input device that detects a specified position by specifying a desired position on a coordinate input panel with an input pen, there are two types of input pens: an input pen whose both ends have a pen tip structure for indicating coordinate input, and the input pen. means for detecting whether a coordinate input instruction has been made with the pen tip of the pen.

[Effect]

In this configuration of the present invention, the detection means operates to detect the direction of the input pen and output the detected contents and specified coordinate data. Furthermore, if it is an electronic device, it operates to execute processing based on the detected input pen and the obtained coordinate data.

【Example】

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1(A) shows a block configuration diagram of an electronic device in an embodiment. In the figure, 100 is a CPU that controls the entire device, and 101
10 is a ROM that stores character patterns for displaying cputoo operation processing procedures and various messages, etc.
A RAM 2 is used as a work area for the CPU 100 and stores information being processed. 103 is an input pen coordinate input unit, the details of which will be described later. 104 is a VRAM for developing images to be displayed, and the images developed here are sequentially read out and displayed on the display unit 105.
It is now displayed on the screen. Note that the coordinate input section 103 in the embodiment adopts a resistive film type that allows the input surface to be transparent, and the display section 10
This coordinate input section 103 is located in front of the display screen of 5. FIG. 1(B) shows a configuration diagram of the coordinate input section 103 of the embodiment. In the figure, 1 is a digitizer device, 2 is a stylus pen device,
3.4 is a pen tip magnetized to S and N, respectively; 5 is a pen tip input point on the digitizer device l; 6 is a magnet plate rotatably held by a shaft 10; 7 is a magnet plate 6 and the shaft 10. It is a slit plate that rotates integrally with the 7° slit, and is made of opaque material except for the 7° slit part. 5 is the magnetic plate 6
8 is a light emitting element that emits light toward the slit plate 7; 9 is a light emitting element 8;
This is a light-receiving element that detects when the slit plate 7 rotates and the slit 7' reaches the upper part of the light. With the above configuration, in this embodiment, it is possible to designate twice as many functions as in the past while using one pen 2. This principle will be explained below. 2 to 5 are views of the relationship between the magnet plate 6 and the pen tip input point 5 of the coordinate input section 103 shown in FIG. 1, viewed from directly above. In FIGS. 2 and 3, the S-pole nib 3 is located at the nib input point 5 of the stylus pen device 2. As shown in FIGS. The pen tip input point 5 moves on the digitizer device l at an angle shown by the arrow, and the magnet plate 6 rotates between two diagonally opposite locations so that the center on the N pole side always faces the pen tip input point 5. . At this time, the slit 7° always exists in a range where the light receiving element 9 can receive the light from the light emitting element 8. Conversely, when the N-pole bend tip 4 is present on the digitizer device 1, as shown in FIG. The slit plate 7 is always located at a position where the slit 7' prevents light emitted from the light emitting element 8 from entering the light emitting element 9. In addition, if the stylus pen device 2 is located apart from the digitizer device 1, or if the S-pole nib 3 is not on the digitizer device, the magnet located diagonally to the digitizer device 1 as shown in FIG. The plate 6 rotates so that the north pole center of the magnet plate 6 faces in the direction indicating the northern part of the earth's magnetic field or in the direction where the south pole nib 3 is located. At this time, the diagonally located magnet plates 6 are in a position where at least one of the light receiving elements 9 cannot receive the light from the light emitting element 8 . In this way, with the configuration shown in FIG. 1, when the stylus pen device 2 is used on the digitizer device 1, whether or not the S-pole nib 3 is in use is determined by one pair. This can be reliably determined by whether or not both of the light receiving elements 9 are receiving light. Therefore, it is necessary to ensure that the user recognizes two modes that the user can easily select, for example, writing mode and erasing mode, by assigning the S-pole pen tip 3 and the N-pole pen tip 4, respectively. Therefore, even under various complicated hierarchical modes, the user can reliably switch between two input modes by simply switching the stylus pen device up and down. In addition, in the embodiment, the coordinate input unit 103 is completely different from the CPU 100 (if it is an independent device, the CPU in the coordinate input unit
(not shown) calculates the coordinate position and sends the result to the main body of the electronic device, information on the currently specified pen orientation is also sent. Of course, there is no problem even if the CPU 100 executes all processing including processing such as coordinate position calculation. <Other Embodiments> In the above-mentioned embodiments, the pen tip polarity detection means of the stylus pen device 2 was determined from the direction of rotation of the rotating magnet plate, but as shown in FIG. , and the cantilever 13 that connects the two, it is resistant to vibrations and shocks because no mechanical rotation system is used, and it is possible to detect the magnetic pole of the pen tip at higher speed. As explained above, in a device that specifies a position using a coordinate input pen, by having both ends of the pen function as a pen tip for inputting coordinates, and by detecting the direction of the pen, it is possible to It is possible to have twice as many selection functions. In the embodiment, the direction of the input pen is detected by magnetic pole detection, but of course it may be detected by other methods.

【Effect of the invention】

As explained above, according to the present invention, a coordinate input unit allows inputting information with more additional functions using a single input pen! And an electronic device using the device can be provided.
