Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view showing the external configuration of an electronic dictionary 10 according to an embodiment of an operation sheet, an operation device, and an electronic device of the present invention.

The electronic device is not only configured as the electronic dictionary 10 described below, but also configured as a PDA (personal digital assistant) with a touch panel, a PC (personal computer), a mobile phone, an e-book, a portable game machine, etc. obtain.

The electronic dictionary 10 has a foldable casing (a lower casing in which a touch panel type operation unit 11 (operation device) is provided and an upper casing in which a touch panel type display unit 12 is provided, which can be expanded/closed via a hinge part 13). It is constructed with a clamshell structure).

FIG. 2 is a side view showing the configuration of the touch panel type operation section 11.

The touch panel type operation unit 11 (operation device) is provided with a transparent sheet 11a (operation sheet) whose details will be described later on its surface, and is configured by laminating a touch panel 11b, a light guide plate 11c, and a piezoelectric element sheet 11d under the transparent sheet 11a. do. A key transmitting LED 11L is provided near the light guide plate 11c.

The touch panel 11b is a touch position detection device that detects a position touched by a user with a finger, a pen, or the like. In the case of a transparent touch panel 11b, it may be provided overlappingly on the transparent sheet 11a. The touch panel 11b of the embodiment uses a resistive film type, but is not limited thereto, and may also use a capacitive type. Moreover, although a piezo element is used for the piezoelectric element sheet 11d, it is not limited thereto.

Further, the touch panel type operation section 11 is configured by providing a control board 11e under the piezoelectric element sheet 11d, and providing a reinforcing plate 11f under the control board 11e.

FIG. 3 is a plan view showing the configuration of the transparent sheet 11a of the touch panel type operation section 11.

The transparent sheet 11a (operation sheet) is formed as a light-shielding area LB that does not allow light to pass through, and a transparent area LT that allows light to pass through, and by guiding light under the sheet 11a, characters and figures for key input can be displayed. A key display section 14s that makes the included symbols (characters) visible, a boundary display section 14b that makes the boundaries of each key visible formed as the transparent area LT, and fixed printing PP are formed on the upper part of the sheet 11a. It has function designation keys 14d, and pen input (touch operation) marks 14m formed by fixed printing PP at equal intervals vertically and horizontally corresponding to a certain range of each key. Although the illustrated pen input mark 14m is a dot, it is not limited to this.

The key display section 14s visually displays symbols including characters and figures corresponding to the QWERTY key or the Japanese syllabary key.

The size of the range (range where each key is located) of the pen input mark 14m corresponds to the size of the display area (screen) of the touch panel display section 12, and the touch panel 11b corresponds to the size of the range (range where each key is located) of the pen input mark 14m. The coordinates of the detected touch position and the coordinates of the display position of the pointer x and trajectory y displayed on the display unit 12 corresponding to the touch position are relatively the same. Therefore, by performing a pen operation on the touch panel 11b using the pen input mark 14m as a guide, input to a desired position on the display section 12 becomes easy.

In addition, in the key display section 14s and the boundary display section 14b formed as the translucent region LT, one square (section) of a key corresponding to a character, for example, is a range of 3 squares x 3 squares of the pen input mark 14m. The corresponding character is formed at a position where its transparent region LT does not overlap with the pen input mark 14m, with the center of one square of the key as a reference.

The horizontal width of the key characters (such as "A", "B", and "C") consisting of single characters is smaller than the interval between the pen input marks 14m (dots), and the vertical width is, for example, the interval between the pen input marks 14m. (dot) spacing is set slightly larger.

In addition, the vertical width of a key character (such as "SHIFT") consisting of multiple characters is smaller than the interval between pen input marks 14 m (dots), and the horizontal width is, for example, 1 interval between pen input marks 14 m (dots). It is set to contain about 2.5 characters.

In addition, depending on the operation of the "SHIFT" key, the single character key character (here, "K", "L") and the switching character key character ("?", "~") that is the target of input are switched. etc.) is set, for example, at the upper right position of the single character key character, to a size corresponding to a quarter of one square of the pen input mark 14m.

On the other hand, the boundary display section 14b has a starting point and an end point for displaying the boundary of any of the keys as a straight line, and is formed corresponding to the position of the pen input mark 14m. The thickness (width) is set to be approximately the same as or slightly narrower than the diameter of the pen input mark 14m (dot).
FIG. 4 is a partially enlarged view showing the relationship between the boundary display section 14b and the pen input mark 14m on the transparent sheet 11a.
Here, in the boundary display section 14b, although both the starting point and the end point of displaying the boundary of the key as a straight line are formed corresponding to the position of the pen input mark 14m, they do not overlap with the pen input mark 14m, and the corresponding It is divided and formed according to the number of pen input marks 14m located between the start point and end point of the key boundary.

The key display section 14s and the boundary display section 14b formed as the light-transmitting area LT allow the light guided by the light guide plate 11c to be transmitted from below the transmitting sheet 11a by lighting the key-transmitting LED 11L shown in FIG. irradiated. Since the irradiated light passes through the transparent region LT, characters and symbols for key input and the boundaries of each key become visible. When the key transmission LED 11L is turned off, the key display section 14s and the boundary display section 14b become invisible, and the function designation key 14d and pen input mark 14m, which are fixedly printed PP, remain visible.

In this way, by setting the relationship in size and position between the key display section 14s and the boundary display section 14b and the pen input mark 14m, good visibility can be ensured without disturbing the mutual balance.

The color of the key character displayed by transmitting light may be set by laminating a color filter under the transparent area LT of the transparent sheet 11a, or by the color of the light emitted from the key transmitting LED 11L. May be set.

The function specification keys 14d are keys for directly specifying the dictionary content categories ([Japanese], [English-Japanese], [Japanese-English], etc.) and [Content List] written in each key.

As shown in FIG. 1, the electronic dictionary 10 of the embodiment has three operation modes: a key input mode [K], a pen input (handwriting) mode [T], and a power-off (power saving) mode [S]. has. Key input mode [K] and pen input (handwriting) mode [T] are examples of the first mode and second mode, respectively.

In the pen input mode [T], as shown in FIG. 1B, the key-transparent LED 11L of the touch panel operation unit 11 is turned off, leaving the function designation key 14d and pen input mark 14m visible. In this state, the touch panel type operation section 11 functions as the pen input section 14T.

The power-off mode [S] is shifted to, for example, when a certain period of time has elapsed during which no user operation is performed on the electronic dictionary 10, and the power-off mode [S] is transitioned to, for example, when a certain period of time has elapsed during which no user operation is performed on the electronic dictionary 10, and the power-off mode [S] is transitioned to, for example, when the electronic dictionary 10 is not operated by the user for a certain period of time. Turn off the power. In this case, the touch panel type operation unit 11 is in a state where the function designation key 14d and the pen input mark 14m are apparently visible, as shown in FIG. 1(B).

FIG. 5 is a block diagram showing the configuration of the electronic circuit of the electronic dictionary 10.

The electronic circuit of the electronic dictionary 10 includes a control unit (CPU: central processing unit) 21 that is a computer. The control unit 21 controls the operation of each part of the circuit according to a dictionary control program 22a stored in advance in a storage unit 22 such as a flash ROM. The number of processors such as CPU may be one or two or more.

Note that at least one of the dictionary control program 22a and dictionary data to be described later may be read from an external recording medium 23 such as a memory card by the recording medium reading section 24 and stored in the storage section 22, or may be stored on the communication network N. It may be downloaded from the Web server (program server here) 30 via the communication unit 25 and stored in the storage unit 22.

The control unit 21 is connected to a storage unit 22, a recording medium reading unit 24, and a communication unit 25 via a data and control bus, as well as a touch panel operation unit 11 and a touch panel display unit shown in FIGS. 1 and 2. Connect 12. Although not shown, an audio output section and an audio input section may be connected to the control section 21.

The storage unit 22 stores a system program that controls the overall operation of the electronic dictionary 10, a communication program for communicating with an external electronic device via the communication unit 25, and stores headwords desired by the user based on dictionary data described later. and a dictionary control program 22a including a dictionary search program for searching and displaying explanatory information such as a translation, word meaning, usage example, and explanation corresponding to the headword.

The storage unit 22 also includes a dictionary data storage area 22b, a mode data storage area 22c, a key input data storage area 22d, a touch position data storage area 22e, and a work data storage area 22f, which are used to perform various functions by the electronic dictionary 10. A storage area is secured to store the data to be used.

The dictionary data storage area 22b stores dictionary data corresponding to various dictionary contents (Japanese dictionary/encyclopedia/English-Japanese dictionary/Japanese-English dictionary/...) including headwords, translations corresponding to the headwords, meanings, usage examples, and explanations. It is stored as data associated with explanatory information such as.

The mode data storage area 22c stores a key input mode [K], a pen input mode [T], or a power off (power saving) mode that is selectively set according to the operation of the electronic dictionary 10 according to the dictionary control program 22a. [S] Any mode data is stored.

The key input data storage area 22d stores key input data indicating the type of key corresponding to the touch position (XY coordinates) detected by the touch panel 11b in response to a touch operation on the function designation key 14d or the key display section 14s. be done.

The touch position data storage area 22e stores touch position data indicating a touch position (XY coordinates) detected by the touch panel 11b in response to a touch operation on the touch panel type operation unit 11.

The work data storage area 22f stores data input in response to user operations and various data acquired or generated by the control unit 21 as the control unit 21 controls the operation of each part of the circuit according to the dictionary control program 22a. The data is temporarily stored (retained) as needed.

In the electronic dictionary 10 configured in this way, the control unit 21 controls the operation of each part of the circuit including the touch panel operation unit 11 according to the instructions of the dictionary control program 22a stored in the storage unit 22, and controls the software and hardware. By working together, various functions are realized including an input function corresponding to a touch operation as described in the operation description below.

Next, the operation of the electronic dictionary 10 according to the embodiment will be explained.

<Key input mode [K]>
FIG. 6 is a flowchart showing processing according to the key input mode [K] of the electronic dictionary 10.

When the operation mode of the electronic dictionary 10 is set to the key input mode [K] by the control unit 21, the control unit 21 turns on the key transparency LED 11L, as shown in (A) of FIG. The key display section 14s and boundary display section 14b of the touch panel operation section 11 are displayed so as to be visible so that the touch panel operation section 11 functions as the key input section 14K (step K1).

When touch position data corresponding to the touch position detected by the touch panel 11b is input to the control unit 21 in response to a touch operation on the touch panel operation unit 11 (step K2), the control unit 21 controls the touch position data corresponding to the touch position detected by the touch panel 11b. It is determined whether a key input has been made based on whether or not is located at a position corresponding to the function designation key 14d or the key display section 14s (step K3).

When it is determined that a key input has been made (step K3 (Yes)), the control section 21 drives the piezoelectric element sheet 11d to vibrate (step K4).

Thereby, in the key input mode [K], the key display section 14s and the boundary display section 14b can be displayed on the touch panel type operation section 11 in a visible manner, allowing the user to perform key input with good operability. Then, each time a key input is performed in response to a touch operation on the touch panel operation section 11, the vibration of the piezoelectric element sheet 11d can tactilely notify the user that a key input has been performed.

Note that even if it is not determined that a key input has been made, the piezoelectric element sheet 11d may be vibrated by detecting a touch position by the touch panel 11b in response to a touch operation on the touch panel type operation unit 11.

The control unit 21 executes processing according to the contents of the input key (step K5).

For example, when arbitrary dictionary content is specified by a touch operation on the function specification key 14d, the control unit 21 causes the touch panel display unit 12 to display an initial screen corresponding to the arbitrary dictionary content. Further, for example, in a state where a headword input screen for inputting a headword corresponding to arbitrary dictionary content is displayed on the touch panel display unit 12, the control unit 21 inputs key-input characters into the headword input screen for inputting a headword corresponding to arbitrary dictionary content. The characters are displayed in the headword input area of the headword input screen as characters that constitute a word.

<Pen input (handwriting) mode [T]>
FIG. 7 is a flowchart showing processing according to the pen input mode [T] of the electronic dictionary 10.

When the operation mode of the electronic dictionary 10 is set to the pen input mode [T] by the control unit 21, the control unit 21 turns off the key transparency LED 11L, as shown in FIG. 1(B). In order for the touch panel operation section 11 to function as the pen input section 14T, the key display section 14s and the boundary display section 14b of the touch panel operation section 11 are made invisible, and the function designation key 14d and pen input mark 14m are turned off. It is left visible (step T1).

When touch position data corresponding to a touch position detected by the touch panel 11b is input to the control unit 21 in response to a touch operation (pen input operation) on the touch panel operation unit 11 (step T2), the control unit 21 It is determined whether the piezoelectric element voltage V generated by the piezoelectric element sheet 11d in response to the touch operation is less than or greater than the reference voltage Vref (steps T3, T4).

Here, for example, if the user is lightly touching the touch panel operation unit 11 and the piezoelectric element voltage V generated in response to the user's touch operation (pen input operation) is less than the reference voltage Vref. If determined (step T3 (Yes)), the control unit 21 causes the touch panel display unit 12 to display the pointer x corresponding to the touch position, and displays the pointer x relative to the touch panel operation unit 11, as shown in FIG. The touch position is shown to the user (step T5).

In this case, the user can move the touch position while referring to the pen input mark 14m on the touch panel operation section 11 to move the pointer x displayed on the touch panel display section 12 to an arbitrary position with good operability. can be moved to

Further, for example, if the user is firmly touching the touch panel operation unit 11 and the piezoelectric element voltage V generated in response to the user's touch operation (pen input operation) is equal to or higher than the reference voltage Vref. If it is determined (step T4 (No)), the control unit 21 displays the trajectory y corresponding to the touch position on the touch panel display unit 12, as shown in FIG. Draw (step T6).

In this case as well, by moving the touch position while referring to the pen input mark 14m on the touch panel type operation unit 11, the user can move the trajectory y of the handwritten character corresponding to the touch position displayed on the touch panel type display unit 12. can be easily drawn as strokes of any character.

As a result, in the pen input mode [T], the user operates the touch panel operation section 11 in response to a touch operation performed while referring to the pen input marks 14m fixedly printed PP on the touch panel operation section 11 at equal intervals vertically and horizontally. When the user is lightly touching the touch panel, the pointer The corresponding trajectory y can be displayed on the touch panel display section 12.

<Power off (power saving) mode [S]>
FIG. 8 is a flowchart showing processing according to the power-off (power saving) mode [S] of the electronic dictionary 10.

For example, when the control unit 21 sets the operation mode of the electronic dictionary 10 to the power-off mode [S] in response to a certain period of time (for example, 3 minutes) elapsed during which no user operation is performed on the electronic dictionary 10. , the control unit 21 turns off (turns off) the touch panel display unit 12, turns off (turns off) the key-transmitting LED 11L, and switches on the touch panel operation unit as shown in FIG. 1(B). The key display section 14s and the boundary display section 14b of No. 11 are made invisible, and the function designation key 14d and the pen input mark 14m are left visible (step S1).

Here, power is not supplied to at least the touch panel display section 12, the key-transmitting LED 11L of the touch panel operation section 11, and the touch panel 11b, thereby saving power.

Thereafter, when the piezoelectric element voltage V generated by the piezoelectric element sheet 11d is detected by the control unit 21 in response to continuous touch operations on the touch panel operation unit 11 for a certain period of time (for example, 3 seconds) or more, the control unit 21 returns the touch panel 11b to the operating state.

Then, touch position data corresponding to the touch position detected by the touch panel 11b is input to the control unit 21 (step S3), and the control unit 21 executes processing according to the touch position of the touch panel operation unit 11 (step S3). S4).

That is, even if the power-off mode [S] is set, if any dictionary content is specified by, for example, a continuous touch operation on the function specification key 14d for a certain period of time (for example, 3 seconds) or more, The control unit 21 immediately causes the touch panel display unit 12 to display an initial screen corresponding to the arbitrary dictionary content. Further, the control section 21 turns on the key-transmitting LED 11L to visually display the key display section 14s and the boundary display section 14b so that the touch panel operation section 11 functions as the key input section 14K.

(Summary of embodiments)
According to the electronic dictionary 10 of the embodiment, the key display section 14s is formed as a transparent region LT through which light passes, and by guiding the light downward, the key display section 14s displays symbols including characters and figures for key input in a visible manner. , a transparent sheet 11a having function designation keys 14d formed by fixed printing PP on the surface, and pen input (touch operation) marks 14m formed by fixed printing PP at equal intervals vertically and horizontally on the surface, A touch panel type operation section 11 is provided, which is configured by stacking a piezoelectric element sheet 11d, a light guide plate 11c provided with a key-transmitting LED 11L, and a touch panel 11b. By switching the key-transparent LED 11L between on and off, the touch panel operation section 11 can be switched between the key input section 14K and the pen input section 14T.

In the key input mode [K], the key-transmitting LED 11L of the touch panel operation section 11 is turned on to visually display the key display section 14s, and the touch panel operation section 11 functions as the key input section 14K. Then, in response to a touch operation on the key display section 14s or the function designation key 14d, key data corresponding to the touch position detected by the touch panel 11b is inputted, and the piezoelectric element sheet 11d is vibrated to prompt the user to input keys. tactile notification that the action has taken place.

In pen input mode [T], the key transparency LED 11L is turned off, the function designation key 14d and the pen input mark 14m remain visible, and the touch panel operation section 11 functions as the pen input section 14T. . If the piezoelectric element voltage V generated by the piezoelectric element sheet 11d is less than the reference voltage Vref in response to a touch operation (pen input operation) performed while referring to the pen input mark 14m of the touch panel operation unit 11, the user determines that the user is lightly touching the touch panel operation unit 11, displays the pointer x corresponding to the touch position on the touch panel display unit 12, and if the voltage is equal to or higher than the reference voltage Vref, the user is inputting with a pen. It is determined that the trajectory y corresponding to the touch position is displayed on the touch panel display unit 12. The user can freely switch between pointer operation and character input operation by adjusting the force applied during pen input.

Therefore, key input and handwritten input can be performed without using a touch panel type display device, which has problems such as high power consumption, large circuit scale and mechanical scale, and high product price, for the touch panel type operation unit 11. This allows the user to perform operations with ease.

Moreover, when the user performs a key input operation, it is possible to notify the user that the key input operation has been correctly performed, and when the user performs a pen input operation, the pointer displays the position of the pen input. In addition to displaying x, the trajectory y of pen input can also be displayed.

It goes without saying that the electronic device of the present invention is applicable not only to the electronic dictionary 10 described as the embodiment, but also to other electronic devices equipped with a touch panel type operation unit 11 similar to the electronic dictionary 10.
