A mobile phone, an IC recorder (a recording device using a solid-state memory) and the like can be mentioned. In recent years, these devices have been provided with other additional functions in addition to the original function of the device.

For example, in a digital camera, by connecting to a personal computer or the like, a shooting place and a shooting date and time are input for a shot image, and a circle mark is attached to a portion of the shot image where attention is required. Some have editing functions. Some IC recorders have an editing function such as inputting a track name by connecting to a personal computer or the like.

Also, in mobile phones, it is becoming popular that a game application can be downloaded and the game can be played using the operation keys provided in the mobile phone.

[0005]

However, the digital camera and the IC recorder must be connected to a personal computer or the like in order to use the above-mentioned functions, so that the editing or the like can be performed on the go. It is practically difficult, and it can be said that such a function is not fully exerted when being carried. In this respect, there is a demand for a small-sized input device capable of inputting characters and the like even when being carried.

Most operation keys of mobile phones are provided with only dial keys or vertical and horizontal cross keys.
In addition, it is not suitable for operations that require quick movement. Therefore, there is a demand to newly add another operation input means.

[0007]

By the way, in these portable electronic devices, for example, in a digital camera, a memory card is often used as a recording medium for recording captured image data. In addition, IC recorders and mobile phones having an IC recorder function, which use a memory card as a recording medium, are becoming popular. That is, in these devices, respectively,
As shown in FIG. 10, many devices having a memory card input slot to which a memory card can be connected are widely used.

In view of the above-mentioned problems, the present invention takes note of this point and makes it possible to connect to various electronic devices having a memory card input slot and input data to the electronic devices. It was decided to configure the device as follows. That is, the touch pad input means, the input data generation means for generating input data according to the operation on the touch pad input means, and the external shape which can be mounted in the memory card input slot are connected to the electronic device. And connection means for inputting the input data generated from the data generation means to the electronic device in a connected state.

As described above, by making the connecting means of the input device into an external shape that can be attached to the memory card input slot, the existing terminal can be used in the electronic device, and therefore a new input terminal can be provided in the electronic device. No need to provide.

Further, this input device need only have a relatively small area for the touch pad input means, so the device itself may be small. Therefore, it is easy to carry the electronic device together with the electronic device, and the input operation can be performed on the electronic device regardless of the location.

Further, by using a touch pad as the input means, it becomes possible to easily input characters and various figures. Therefore, when the input device of the present invention is used as the operation means for indicating the direction, it is possible to instruct the electronic device to operate in any direction.

As described above, the main body device is provided with the display control module 20a for inputting the XY coordinate data and controlling the display based on the input. Therefore, by attaching the touch pad input device 1 to this main device and inputting data such as XY coordinate data as described with reference to FIG. 2, the microcomputer 20 causes the display control module 20a to input the XY coordinate data and the like. It is possible to perform display control on the display unit 22 based on the above data and perform various displays on the display unit 22 based on the XY coordinate data.

As described above, the main body device is provided with the display control module 20a for performing display control based on the XY coordinate data, and the display control according to the XY coordinate data input from the touch pad input device 1 is realized. In the following, as a specific example of display control on the main device side according to XY coordinate data input of the touch pad input device 1, a case where the main device is a digital camera, a mobile phone, an IC recorder explain.

First, when the main body device is an IC recorder, the external appearance of the state in which the touch pad input device 1 is mounted is as shown in FIG. 4 (a). As shown in this figure, when the touch pad input device 1 is turned upside down due to the structure of the main device, the touch pad input device 1 is physically provided with a coordinate conversion function that absorbs the difference in orientation in advance. In addition, the same touch pad input device 1 can be applied to the main body device of any structure.

When the main unit is the IC recorder 40, the character recognition / display module 41 shown in FIG. 6A is provided as the display control module 20a of the microcomputer 20. The character recognition / display module 41 is a module for recognizing characters based on the XY coordinate data received from the touch pad input device 1 in time series and displaying the recognized characters on the display unit 22. Hereinafter, the character recognition and display control of the recognized character by the character recognition / display module 41 will be described with reference to FIG.

First, when the IC recorder 40 is in the input mode of a track name or the like and is in the state of waiting for a character input operation, as shown in FIG. 7A, the touch of the touch pad input device 1 is touched. When “a” is traced on the surface 2 with a fingertip or the like as indicated by a wavy line, in the touch pad input device 1, the pad control unit 10 generates XY coordinate data of the traced trajectory, which is input to the IC recorder 40. It Then, the XY coordinate data is input to the microcomputer 20, and the character recognition / display module 41 performs character recognition based on the XY coordinate data.

The character recognition processing by the character recognition / display module 41 is formed by sequentially plotting the XY coordinate data input in time series in the plotting memory area in the memory 21, for example. This is done by recognizing the figure that Character recognition / display module 41
Refers to the character font data in the memory 21 on the basis of the figure thus recognized, reads out a character having a similar shape, and causes the display unit 21 to display the read character. As a result, the character corresponding to the locus traced by the finger or the like on the touch surface 2 is displayed on the display unit 21.

At this point, the user operates the operation switch 5 of the touch pad input device 1 when, for example, a character input by tracing on the touch surface 2 with a finger or the like is correctly displayed on the display unit 21. Confirm the input of the displayed characters,
Alternatively, when the character input by tracing the touch surface 2 with a finger or the like is not correctly displayed on the display unit 21, the operation switch 6 of the touch pad input device 1 can be operated to redo the input. In addition, for example, when a word formed by inputting characters in this way is converted into Kanji on the main body device side, these operation switches 5 and 6 are used to determine the input of the converted Kanji character or make an erroneous conversion. Can also be notified.

As described above, the touch pad input device 1 can be used to input characters to the IC recorder 40.

In addition, in the case of a digital camera, a viewfinder and a display unit (display unit 22) are usually provided on the surface opposite to the surface on which the lens is provided, and accordingly, the touch surface 2 is also on the same surface for convenience of operation. It is preferable that the touch pad input device 1 is mounted upside down as shown in the drawing.

When the main body device is the digital camera 50, the character recognition / display module 51 and the drawing display module 52 shown in FIG. 6B are provided as the display control module 20a of the microcomputer 20. The character recognition / display module 51 is a module for performing display control at the time of character input in the case of inputting data such as location and date in a captured image, but the basic operation is the character recognition / display module described above. Since it is almost the same as 41,
The description is omitted here. The drawing display module 52 is a module for displaying a drawing based on the XY coordinate data received from the touch pad input device 1 in time series on the display unit 22. The display control for the drawing display by the drawing display module 52 will be described below with reference to FIG.

First, in the case where the digital camera 50 is in the state of editing the captured image, for example, the captured image is displayed on the display unit as shown in FIG. When the touch surface 2 of the touch pad input device 1 is traced by a wavy line with a fingertip or the like, in the touch pad input device 1, the pad control unit 10 generates XY coordinate data of the traced locus.
This is input to the digital camera 50. Then, the XY coordinate data is input to the microcomputer 20 and processed in the drawing display module 52.

The processing by the drawing display module 52 is performed, for example, for the plotting memory area in the memory 21.
This is performed by sequentially plotting the XY coordinate data input in time series and sequentially drawing at the position on the display unit 22 (display) corresponding to this position. Through such processing, the display unit 22 continuously displays the drawing at the position corresponding to the XY coordinate data sequentially input from the touch pad input device 1. As a result, as shown in FIG. 7B, the touch surface 2 is traced with a finger or the like, and at the same time, the position and shape of the trace corresponding to the position of the trace traced on the touch surface 2 are displayed on the display unit 22. Will be done.

At this point, for example, when the user wants to confirm the input of the displayed drawing, he or she wants to confirm the input by operating the operation switch 5 of the touch pad input device 1 or to redo the input. In this case, the operation switch 6 of the touch pad input device 1 can be operated to redo the input.

As described above, drawing input using the touch pad input device 1 is performed on the digital camera 50.

The display control module 20a of the microcomputer 20 includes a character recognition / display module 61 and a cursor position recognition / display module 62 shown in FIG. 6 (c).

The character recognition / display module 61 is a module for performing display control when inputting characters when inputting data such as a name and a telephone number when the mobile phone 60 is in the phonebook registration mode. Since the basic operation is almost the same as that of the character recognition / display module 41 described above, the description thereof is omitted here. The cursor position recognition / display module 62 is a module for displaying a cursor or a pointer at a position on the screen of the display unit 22 based on the XY coordinate data received from the touch pad input device 1.

This cursor position recognition / display module 6
2 operates when the cursor on the screen is operated while the mobile phone 60 is accessing the Internet, for example. In this case, first, when the touch surface 2 is operated by a fingertip or the like in the touch pad input device 1 and the XY coordinate data corresponding to this operation is input to the microcomputer 20, the cursor position recognition / display module 6
2 plots the input XY coordinate data in the plotting memory area in the memory 21 and recognizes the position on the display unit 22 corresponding to this position. Then, the cursor position recognition / display module 62 moves the cursor displayed on the display unit 22 to this recognized position.

Cursor position recognition / display module 62
However, by continuously performing this operation based on the XY coordinate data sequentially input to the microcomputer 20, the touch surface 2 is traced with a finger or the like, and at the same time, the cursor displayed on the display unit 22 moves the touch surface 2 The images are displayed so as to be sequentially moved to the position on the display unit 22 corresponding to the position of the traced path. That is, the position of the cursor on the display unit 22 can be moved according to the movement of the fingertip or the like on the touch surface 2.

The user operates the operation switch operation switch 5 of the touch pad input device 1 to input the operation when the user decides to execute the operation by matching the cursor with the operation button displayed on the screen. Can be confirmed.

Further, such a touch pad input device 1
And corresponding cursor position recognition / display module 62

The touch surface 2 is shown when the mobile phone 60 is in a waiting state for a game operation as shown in FIG. 8 with the downloaded game application or the game application attached to the device being activated. When the cursor position recognition / display module 62 is operated, the game cursor displayed on the display unit 22 is displayed so as to move according to the operation.

At this time, depending on the operation of the touch pad input device 1 and the corresponding cursor position recognition / display module 62, the cursor can be moved in accordance with the movement of the fingertip of the touch surface 2 as described above. Therefore, the game cursor can be moved slowly by tracing the touch surface 2 slowly, and can be moved quickly by tracing the touch surface 2 quickly. Therefore, when a quick operation such as a game operation is required, the touch pad input device 1
Can be said to be suitable as an operator.

The above is the description of the touch pad input device 1 according to the present embodiment. As described above, the touch pad input device 1 can be attached to the main body device by forming the connecting portion 3 into an external shape that can be attached to the memory card input slot provided in the main body device.

Therefore, it is easy to carry the electronic device together with the electronic device, and the input operation can be performed on the electronic device regardless of the location.

Furthermore, by using a touch pad as the input means, it becomes possible to input characters and various figures to the electronic device. For this reason, when the touch pad input device 1 is used as an operation means for instructing a direction, it is possible to instruct the electronic device to operate in any direction.

In the present embodiment, the XY coordinate data is transmitted from the pad control unit 10 of the touch pad input device 1 to the microcomputer 20 of the main equipment, and the microcomputer 20 sends this X
Although a method of performing character recognition based on Y coordinate data is adopted, instead of this, the pad control unit 10 uses X

It is not limited to this. Further, according to these specific examples, the respective functions of the display control module 20a provided in the microcomputer 20 of the main body device are merely examples, and the present invention is not limited to these.

Further, in the present embodiment, the touch pad input device 1 is provided with the operation switches 5 and 6, and the method of notifying the main body device of the confirmation or redo of the input is adopted. An operation switch for notifying execution of conversion when converting input characters into Kanji, an operation switch for notifying the forward display of conversion candidates, and the like may be newly added. Alternatively, for example, when one point on the touch surface 2 is quickly pressed once without providing any of these operation switches, or when two points are continuously pressed.
A method may be used in which the time of pressing is used as a signal notifying the confirmation of the input or the redone of the input.
