Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an information processing device that performs processing in accordance with information input from an input device.

(Prior Art) Conventionally, workstations and personal computers have traditionally been configured with a display and a keyboard. Further, a mouse or the like is used as a pointing device.

Incidentally, recently, an integrated handwriting input/display device consisting of a transparent tablet for inputting coordinate data overlaid on a liquid crystal display has been developed, and its ease of use is attracting attention.

The integrated handwriting input/display device allows instructions to be given by directly pointing to objects displayed on a liquid crystal display, rather than indirectly by moving a cursor with a mouse. Furthermore, when characters, symbols, and lines are written by hand, the handwriting is displayed at the handwritten position, making it feel as if writing with a pencil on paper, making it easier for humans to operate.

A conventional workstation using such an integrated handwriting input/display device is shown in FIG. This species,
Workstations use an integrated handwriting input/display device as the main man-machine interface, and either do not have a keyboard or have the ability to optionally connect a keyboard as an additional device.

(Problems to be Solved by the Invention) An information processing device such as a workstation using an integrated handwriting input/display device can be easily operated by anyone since there is no need to become proficient in its operation. however,
For example, when inputting a large amount of character text, a person accustomed to keyboard operations can input data more efficiently by using the keyboard than by using the integrated handwriting input display device. However, since information processing apparatuses using integrated handwriting input and display devices are usually not equipped with a keyboard, it is necessary to input data using an inefficient method.

In addition, if a keyboard is provided for data input as described above, as shown in FIG.
There was a problem that the area occupied was large. Furthermore, since a keyboard is connected as an additional device, there is a problem in that it is inconvenient to carry the device when moving it.

The present invention has been made in view of the above-mentioned points, and an object of the present invention is to provide an information processing device that has a keyboard and an integrated handwriting input display device, is easy to carry, and occupies a small desk space when in use. purpose.

[Structure of the Invention] (Means for Solving the Problems) The present invention integrates a tablet device for inputting coordinates by overlapping it on the display surface of a display device, and in which an arbitrary instruction on the tablet device is integrated. an integrated handwriting input/display device for inputting coordinate data indicating a position, and a keyboard; the integrated handwriting input/display device and the keyboard are arranged such that a display surface and a keyboard surface of the integrated handwriting input/display device face each other; It is configured to include a rotation support mechanism that can be rotated from one position to an arbitrary opening angle position.

The present invention also provides a processing device main body and a tablet device for inputting coordinates, which is integrated by overlapping a display surface of a display device provided on the top surface of the device main body, wherein an integrated handwriting input/display device for inputting coordinate data indicating a position indicated by a keyboard;
The integrated handwriting input display device provided on the upper surface of the device body and the keyboard can be rotated from a position where the display surface of the integrated handwriting input display device and the keyboard face each other to an arbitrary opening angle. The opening angle is also provided with a rotation support mechanism that maintains the opening angle.

The present invention also provides a state detection means for detecting whether either the integrated handwriting input display device or the keyboard is installed in a substantially horizontal state; The present invention further includes a changing means for changing the display content and the detection position of the coordinate data in the integrated handwriting display device.

(Function) According to such a configuration, the integrated handwriting input display device,
Since it is equipped with a keyboard, data can be entered by selecting one depending on the processing content (purpose of use).

Further, the processing device main body is provided with an integrated handwriting input display device, and the keyboard can be held in an open state from a position facing the surface of the integrated handwriting input display device (closed state) to any angle. As a result, when data is input mainly from an integrated handwriting input display device,
When the main body of the processing device is in a substantially horizontal state, the keyboard can be supported at an angle to the horizontal surface so that it does not interfere with handwriting input, etc. In addition, when data is mainly input from a keyboard, the integrated handwriting input display device is supported at an angle to the horizontal surface and the display surface is visually checked when the keyboard is in a nearly horizontal position (at a predetermined angle). You can make it easier.

In addition, it is detected whether the integrated handwriting input display device or the keyboard is installed in a substantially horizontal state and is about to be used for data input, and the display content on the integrated handwriting input display device is determined according to the detection result. Since the detection position of the coordinate data is changed, the device can be easily operated.

FIG. 1 is a perspective view showing the external configuration of an information processing apparatus (workstation) according to the same embodiment. This figure shows the installation state of the workstation when inputting data using the integrated handwriting manual display device 14 (described later) (hereinafter referred to as handwriting manual mode). Figure 2 is a side view of the workstation showing the installation state of the workstation when data is input using the keyboard 18 (hereinafter referred to as keyboard input mode), which will be described later, and Figure 3 is an integrated handwriting input described later. FIG. 3 is a side view showing how the workstation is installed when data is input using the display device 14. FIG.

In FIGS. 1 to 3, 10 is a workstation main body, and a microprocessor (MPU) is installed inside the casing.
), memory, hard disk drive (HDD), and floppy disk drive (FDD). A leg 12 with a switch is provided on the bottom 10a of the main body 10. The switch-equipped leg 12 opens (off) when the device is installed in the state shown in FIG. 2, and is pressed (on) when the device is installed in the state shown in FIG. . The detailed configuration of this switch-equipped leg 12 and the details of internal processing according to the operation of the switch will be described later.

An integrated handwriting input/display device j4 is provided on the top surface tab of the main body [0. The integrated handwriting input display device 14 is composed of a liquid crystal display and a transparent tab for inputting coordinate data. When an arbitrary position is specified using a pen, coordinate data indicating that position is input.As methods for manually inputting this coordinate data, for example, an electromagnetic induction method, a capacitive coupling method, and a pressure-sensitive method are used. .Here, it is assumed that an electromagnetic induction method is used.

Further, a pivot mechanism 16 (
A rotation support mechanism) is provided. The pivot mechanism 16 moves the keyboard 18 from a position (when the keyboard 18 is closed) such that the display surface of the integrated handwriting input display device 14 provided in the main body part 10 and the keyboard surface face each other.
It is designed to be freely rotatable up to a predetermined opening angle. Also,
The pivot mechanism 16 is capable of supporting the keyboard 18 at an arbitrary opening angle and maintaining the state shown in FIG. 2.

The side surface 10e of the main body 10 has, for example, a floppy disk (FD) insertion slot, R3, which is an interface between various functions housed in the main body housing and external devices.
Various connectors 19 are provided including connectors for connecting (232C connector, keyboard 00 key, etc.).

Next, a specific implementation method and internal operation of the embodiment will be explained.

First, a method of installing the workstation in the keyboard input mode in the same embodiment will be explained. In this case, a workstation is installed as shown in FIG. As shown in the figure, the workstation is installed with the main body 10 erected by the rear end 10d of the main body 10 and the upper end of the keyboard 18 (the opposite side supported by the pivot mechanism 1G). be done. At this time, the pivot mechanism 16 supports the keyboard I8 at any opening angle, so the installed state of the workstation is fixed.

Further, the pivot mechanism 16 is provided at a position that makes it easier to input data by adjusting the angle between the desk surface on which the workstation is installed and the keyboard 18 when the pivot mechanism 16 is in the state shown in FIG. FIG. 4 shows an example of a display in which a document is being created using the Japanese word processor function in the keyboard input mode.

Further, the switch leg 12 provided on the bottom 10a of the main body 10 is in an off state. An example of a detailed configuration of the switch leg 12 in the off state is shown in FIG.

The switch 4o that actually operates on/off is a printed board 41. (on the bottom 10a side).

A force is applied to the insulating material movable body 43, which is a leg portion that moves through a hole provided in the main body casing 42, by a spring 45 fixed to the casing with, for example, a screw 44 so as to be pushed outward from the casing. It is being

Therefore, the movable part 46 of the switch 40 is slightly separated from the insulator movable body 43 (off state).

Next, a method of installing a workstation in handwriting input mode will be described. In this case, a workstation is installed as shown in FIG. As shown in the figure, the workstation is installed with the bottom 10a of the main body 10 facing the desk surface. At this time, the switch leg 12 is in an on state. An example of the detailed configuration of the switch leg 12 in the on state is shown in the seventh section.
Shown in the figure.

When the integrated handwriting input/display device 14 is installed in a workstation as shown in FIG. Pushed against force. In reality, the state is as shown in FIG. 7, and the insulator movable body 43 pushes the movable part 46 of the switch 40 to turn it on. Note that at this time, the weight of the device is transferred from the main body casing 42 to the insulator movable body 4 through the collar 47 of the insulator movable body 43.
Rubber 48 attached to the bottom of 3 is added to the desk top surface. Therefore, excessive force is not applied to the movable portion 46 of the switch 40.

The on/off state of switch 42 is read by the MPU in the workstation. The MPU performs control to invert the display of the integrated handwriting input display device 14 according to this on/off state.

An example of a block diagram showing the configuration of a display circuit for performing this control is shown in FIG.

In FIG. 8, a data bus 51, an address bus 52
is connected to an MPU (not shown) that controls the entire device. An LCD controller 53 and a bus driver 54 are connected to the data bus 51.

The address bus 52 is connected to (an input end of) an LCD controller 53 and a 3-way multiplexer 55. Address data given to LCD controller 53 is for accessing an I10 register (not shown) within LCD controller 53. For accessing the I10 address, some bits of the address data are not used. The other two input terminals of the three-way multiplexer 55 are connected to the LCD controller 53 and an address bus from the LCD controller 53 via a subtraction circuit 56. The output end of the three-way multiplexer 55 is connected to a bitmap memory (BMM) 57. The 8MM57 includes a bus driver 54 and 3
Display data regarding the content to be displayed, which is read or written according to data from the way multiplexer 55, is stored. A bit order inversion multiplexer 58 is connected to the BMM 57 and the bus driver 54 . The LCD controller 53 is connected to the output terminal of the bit order inversion multiplexer 58 .

The display data stored in the 8MM 57 is transferred to the LCD controller 53 via the bit order inversion multiplexer 58. The LCD controller 53 drives and controls the LCD display 59 based on display data.

The 8MM57 is addressed in 8 bits in parallel and addresses 0 to (n) corresponding to a screen of 8n dots horizontally and m dots vertically.
m-1) address is used. The subtraction circuit 56 outputs (nm-a-1) for the input address a.

The 3-way multiplexer 62 selects the address data from the address bus 52 when the MPU accesses the 8MM 55, and when the LCD controller 53 drives and controls the LCD display 59, the 3-way multiplexer 62 selects the address data from the address bus 52 and selects whether the MPU is instructing vertical or horizontal inversion ( Either the address data from the subtraction circuit 56 or the address data from the LCD controller 56 is selected depending on whether or not control information for an inversion instruction has been given. Control information for this reversal instruction is not shown. This may be realized by having the MPU write the control information into one of the I10 registers in the LCD controller 53, or may be realized by providing a flip-flop that can be controlled by the MPU. In addition, M.P.
U gives a reversal instruction according to the on/off state of the switch 12 of the switch leg 12. The bit order inversion multiplexer 63 outputs the input 8 bits as they are, or reverses the bit order of the input 8 bits (0-7, 1→6...7→O).

For example, LCD display 59 is 640 dots)
If the resolution is 0 dots, the contents of addresses O to 79 of the 8MM57 correspond to the top row of the screen, and the lower right of the screen is 80 x 400-1. Corresponds to address -31999. In order to switch the display contents vertically and horizontally, when reading the contents of the 8 dots at the top left of the screen from the 8MM57, read address 31999 instead of address 0,
It is only necessary to read address 31998 when reading address 1, and so on. That is, in the subtraction circuit 56, L
(32000-A-1,) is calculated for the address a sent from the CD controller 53 to the 8MM 57. If the image is to be displayed by inverting the image vertically and horizontally, the output of the subtraction circuit 55 may be selected using the three-way multiplexer 55.

Here, 8MM55 has a configuration of 8 bits/word,
Eight bits corresponding to eight dots lined up horizontally on the screen are read out at the same time.

Therefore, simply by replacing the addresses in the three-way multiplexer 55, the order of the eight bits cannot be reversed. Therefore, the bit order of the 8 bits read out in parallel is changed by the bit order inverting multiplexer 58 to realize inverted display.

On the other hand, by pointing a point on the transparent tablet of the integrated handwriting input/display device j4 using a pen, the position (coordinate data indicating the point) can be read, but the displayed content of this coordinate data is also reversed vertically and horizontally. It must be converted accordingly.

The MPU turns on/off the switch 40 of the switch leg 12.
Depending on the off state, conversion control of the specified position on one knot of the transparent tab is performed. A block diagram showing an example of the configuration of a coordinate input circuit for performing this control is shown in FIG. The operation of this circuit is, in principle, similar to the display circuit shown in FIG. In the case of the display circuit shown in Fig. 8, the two-dimensional address is 1 as the address of 8MM57.
In contrast to handling things converted to dimensional addresses, the 9th
In the case of the coordinate input circuit shown in the figure, the only difference is that the two-dimensional address remains the same.

In FIG. 9, a tablet control circuit 71 and a bus driver 72 are connected to a data bus 51.

A tablet control device 71 is connected to the address bus 52 . A transparent tablet 73 is connected to the tab 1/soto control circuit 71. Under the control of the tablet control circuit 71, the transparent tablet 73 sequentially scans the screen (tablet matrix) in the X direction and then in the Y direction, for example electromagnetically, and receives a scanning signal sensed by a pen (not shown). It is sent back to the tablet control circuit 71. Further, an X counter 74 and a Y counter 75 are connected to the tablet control circuit 71. The tablet control circuit 71 is
In synchronization with the scanning of the transparent tablet 73, the X counter 74.
The Y counter 75 is reset and counted up. The tablet control circuit 71 then controls the transparent tablet 73.
The X counter 74 and the Y counter 75 stop counting at a point corresponding to the pen position by processing the sensing signal sent back from the pen. When the X and Y scans are completed, the tablet control circuit 72 sends an interrupt signal (a signal line for this purpose is not shown) to the MPU. The X counter 74 and the Y counter 75 output their count values to the 4-way multiplexer 76. The other two input terminals of the 4-way multiplexer 76 are connected to an X counter 74 and a Y counter 74 via subtraction circuits 77 and 78 corresponding to the
A bus from counter 74 is connected. When the matrix of the transparent tablet 73 is 8n dots horizontally and m dots vertically (same as the resolution of the LCD display), the respective outputs of the X counter 74 and Y counter 75 (that is, the respective inputs of the subtraction circuits 77 and 78) When x+Y, the subtraction circuit 77 outputs (n −x−1,),
The subtraction circuit 78 outputs (m-y-1). The 4-way multiplexer 76 selects and outputs either the address data from the X counter 74 and the Y counter 74 or the address data via the subtraction circuits 77 and 78 according to the control information instructing the vertical and horizontal inversion. do.

The MPU receives an X counter 74 and a Y counter via a data bus 51.
By reading the contents of the counter 75, the position indicated by the pen can be known. After that, the MPU sends a command to the tablet control circuit 71 and repeats the above process again. In this way, the LC of the integrated handwriting input display device 14
Corresponding to the inverted display on the D-display, the coordinate position indicated by the pen is inverted.

In this way, the integrated handwriting input display device I4 is provided on the upper surface portion 10b of the main body 10, and is configured to be rotatable by the pivot mechanism 16 from a position facing the integrated handwriting input display device. Handwriting input display device I

4, by placing the bottom portion 10a of the main body portion 1.0 on a desk, it becomes easier to write letters, etc. on the transparent tablet.

Further, when using the keyboard 18, as shown in FIG. Od and keyboard 18
By supporting the device by the tip (in the open state) of the keyboard 18, inputting data from the keyboard 18 is facilitated, and the display screen of the integrated handwriting input/display device 14 can be installed in a position where it is easily visible. can.

Further, since the keyboard 18 can be locked in a closed state when not in use, the device can be moved much more easily than in the conventional keyboard connection method.

Also, an integrated handwriting input display device 14 and a keyboard 18
Since they are locked in a facing state, the display surface of the integrated handwriting input/display device 14 is also protected at the same time.

Furthermore, by changing the installation state of the device (changing the input means used), the switch state (on/off) of the switch leg 12 can be changed, the display screen setting (inverted display), and the integrated handwriting input display A transformation of the coordinate position input from the device 14 is performed.

In the above embodiment, it is determined whether the integrated handwriting input display device 14 or the keyboard 18 is used.
Legs 1 with switches provided on the bottom 10a of the main body IO
Although the MPU is notified based on the on/off state of No. 2, other methods may be used.

For example, by utilizing the fact that the posture of the main body changes depending on the input means (integrated handwriting input display device 14, keyboard 18) used, the input means to be used can be determined by providing a posture sensor inside the main body. A dedicated switch for indicating the input means may be provided, which can be manually turned on/off.

Furthermore, in the embodiment described above, it has been explained that when data is input using the keyboard 18, data is not input from the integrated handwriting input/display device 14, but it is also possible to use both together.

[Effects of the Invention] As described above, according to the present invention, a keyboard and an integrated handwriting input/display device are provided, and data can be input by arbitrarily selecting from either of them. Since there is no need to connect and use a keyboard in addition to the information processing device that the device has, even if a keyboard is desired to be used in conjunction with the device, the area occupied on the desk can be reduced.

In addition, the keyboard is attached by a rotation support mechanism,
When not in use, it is fixed so as to face the display surface of the integrated handwriting input/display device, making it easy to move the device.
