Description

Description: TECHNICAL FIELD The present invention relates to an electronic organizer having an electronic processing function.

[Prior Art] In recent years, since IC cards and large-capacity memories have become readily available, ROMs and RAMs are made into card types as disclosed in JP-A-62-107360. Electronic devices used for various purposes by replacing a card with a portable case have been proposed. In this case, if various ROMs in which different data are written are prepared, they can be used for various purposes only by replacing the card.

[Problems to be Solved by the Invention] However, such a conventional device requires a keyboard for data input, and the area of the portion is inevitably required, and there is a limit to downsizing. To solve this problem, there is a keyboard that is displayed on the screen and key data is input by touching necessary items, but all keys are displayed on a limited screen, so operability is very poor Since the position of the key is determined, there is no flexibility in setting the position of the key. In addition, since a method of sequentially scanning from the end is used to detect a touched portion, there is a problem that it takes too much time to detect depending on a touched location. Further, if the position of the key is freely set and the extracted coordinate values are directly processed, there is a problem that the size of the program becomes very large.

Means for Solving the Problems In order to solve such a problem, the present invention relates to an electronic organizer device using a touch panel as a display unit. The coordinates are given, and a group of the coordinates is divided into a block to divide the entire display unit into a plurality of blocks.
When one of the blocks is touched, a coordinate input unit that outputs a coordinate signal of the pressed portion, and when the coordinate signal supplied from the coordinate input unit represents a plurality of coordinates, only one of them is selected. An input coordinate extracting means for outputting the key coordinates displayed on the display unit and a key code data of the key in association with each other; The second memory stores the name of the key that is associated with the block and the code without the registration key in association with the block where no key is displayed, and stores the coordinate signal output from the input coordinate extracting means. When supplied, it identifies the block containing the coordinates of this coordinate signal,
A procedure for reading a key name or a code without a registration key corresponding to the specified block from the second memory, and a procedure for reading a coordinate range corresponding to the read key name from the first memory. Determining whether or not the coordinates of the coordinate signal are included in the coordinate range, thereby identifying the key touched on the display unit and outputting the key code data thereof. Means.

[Operation] When a certain block is touched, detection is performed for each block, the key name registered in the detected block is read, and the touched coordinates are the coordinate area of the key corresponding to the key name. Judge whether or not
If it is within that area, the key code registered there is output.

2. Embodiment Corresponding to Claims FIG. 2 is a diagram of a display unit displayed by applying an embodiment of the present invention, and FIG. 3 is a block diagram of a main part. In FIG. 2, the display unit is a touch panel, and necessary processing is performed by touching a predetermined portion with a finger in accordance with the instruction content on the screen. FIG. 2 shows an example in which the key of the part selected by the coordinate range designation signal is displayed in this manner. When only the keyboards of A, B, C, D, and E are required, as shown in FIG. Is displayed in an easy-to-use form.

Figure 3 is a circuit for outputting a key code, the arithmetic processing unit 1 _12, the coordinate input unit 1 _13, the input coordinate extraction unit 1 _14, table 1 _15, is composed of the memory 1 _15, the arithmetic processing unit 1 ₁₂ coordinates A range designation signal and a key code extraction instruction are supplied.

Coordinate range designation signal is one of the signals carried what displayed on the display unit 1 _1, for example, key A is an example of FIG. 2, B, C, D, E
Is a signal for displaying the range. The display unit is divided into 50 blocks Ia to Xe as shown in FIG. Since the assignment of each key is assumed to be a rectangular key here, the range of each key can be specified by the coordinate value of the upper left corner and the coordinate value of the lower right corner of the key. In FIG. 2, if the coordinates of the horizontal axis of the screen are defined as 0 to 99 and the coordinates of the vertical direction are defined as 0 to 49, the coordinates of the key A are (left 4, upper 5);
Below 15). The method of dividing the blocks is arbitrary,
In the example of the figure, a block having a size of 10 in both the vertical and horizontal directions is assumed to be one block. For example, the coordinates of the IV d block are (left 30,
(Upper 30); (right 40, lower 40). When keys A to E are set as shown in FIG.
Two types of tables such as a table and a second table are created.

Then, it is checked which key is registered from the table based on the pressed coordinates, and only the registered keys are compared in range from the table to determine the input key. When portion of this time is pushed, the coordinate input unit 1 ₁₃ is to output a coordinate signal of the pressed portion, the input coordinate extraction unit
Is output only one of them the coordinate by one _14, so that the block is identified. For example, block VI
II b is pressed and one of the coordinates in the block (75,18)
Is input, it is known from the coordinate values that the block is a block of VIIIb, and it can be seen from Table 2 that the keys (3) and (5) are registered. From Table 1, the key (3) corresponds to the key C, and the key (5) corresponds to the key E. However, since the detected coordinates are (75, 18), by comparing these coordinates with the coordinates of the keys C and E, it is immediately apparent that the coordinates do not correspond to the key E. Therefore, since the key C falls within the coordinate range, the key code C is output. The present invention is characterized in that a key code is directly output instead of outputting a coordinate signal as in the related art.
It also checks which block is pressed, checks which key is registered in that block, and determines which key code to output from that data. To search all keys sequentially,
It is possible to specify a portion pressed at a higher speed than that converted into a key code.

In FIG. 2, the block of the key C is also overlapped with the keys D and E, but in such a portion, the search priority is determined as shown in Table 1, and the key code is determined in that order. Just do it. The search order in Table 1 indicates this priority.

Another Embodiment FIG. 4 is a view showing another embodiment, and
The upper left corner and the lower left corner are cut diagonally, and the cut portion is the center line 4 ₂ of the expansion card mounting hole.
The portion corresponding to the upper, is provided transmitter 4 ₁ and the receiver 4 _3. Also attach the transmission unit 1 ₂₁ in the portion corresponding to the receiver 4 ₃ receiver 1 ₂₀ in the portion corresponding to the transmitter 4 ₁ a on the center line of the body 1. In this case, the receiver 1 ₂₀
And the transmission unit 1 ₂₁ is non-directional, the transmission of the expansion card side portion 4 ₁
And the receiver 4 ₃ has to have a receiving portion 1 _20, facing the transmitter 1 ₂₁ directional.

In thus constructed apparatus, the transmission unit 4 of _the expansion card side is provided at the center line of the hole for mounting, the main body side of the receiving part
Since 1 ₂₀ is provided on the center line of the main unit, even if there is play within the allowable range of the mounting device when installing the expansion card,
Directional deviation is less likely to occur as compared with the case where it is attached to another part.

In FIG. 4, the cutout portion of the expansion card is located at the upper left corner, but may be located at the lower left corner. Alternatively, as shown by a dotted line in FIG. 4 (in FIG. A V-shaped cut may be provided, and a transmitting / receiving unit may be provided in that portion. Also, the portion where the transmitting / receiving section is attached is not linear as shown in FIG. 4, but if the convex chamfer shown in FIG. Reception becomes easier. Further, by performing a concave chamfer as shown in FIG. 5 (b), energy can be concentrated on the receiving element, and the efficiency can be further improved by using a reflective coating or a reflective plate on the cut surface.

By removing ₂₃ , it can be used as an OHP sheet. In this way, the display screen can be enlarged and projected, so that it is suitable for many people to watch at the same time.

FIG. 7 is a block diagram showing another embodiment. In the figure, when the display direction is designated by the display direction designation means _12a , the signal is transmitted to the switching table _12b and the display switching means _1a .
Supplied to _2d . Therefore signal for display output from the display RAM 1 _2e is supplied to the display device 1 _2f while being direction change, is displayed. Therefore, even if the screen is turned vertically or horizontally by the holding method of this device, the display direction is normal for the operator.

The switching table _12b stores a key code suitable for the display direction, and the key code is read out according to a designation signal from the display direction designation means _12a . On the other hand, the direction key is pressed while viewed from the operator.
That is, when the cursor is to be moved upward, the operator presses a cross-shaped directional key and presses an upper part thereof. As a result, a signal corresponding to the position is output from the direction key.
As described above, the key code in the direction designated by the display direction designation means _12a is output from the switching table _12b , and this key code is as shown in Table 3, for example.

In other words, the figure displayed as a solid line in FIG.

The feature of this circuit resides in a portion composed of transistors Q1 and Q2, resistors R3 and R4, a diode D1, coils L1 and L2, and a capacitor C3. To transmit information by electromagnetic induction,
It is desirable that the current flowing through the coil be large. However, this circuit is assumed to be driven by, for example, a coin-shaped lithium battery. However, this battery cannot flow a large current, and forcibly flowing a large current leads to deterioration of the battery. In order to cover this problem, the resistor R3 is for example 270
Ohms, resistor R4 is set to 56 ohms, and capacitor C3 is set to 10,000 PF, effectively solving the problem.

That is, the capacitor C3 is charged with a small current through 270 ohms of the resistor R3, thereby reducing the load on the battery. On the other hand, when the capacitor C3 is discharged, a large current flows through the coil L1 via 56 ohms of the resistor R4 to generate a large magnetic field.

Signal transmission through this circuit is performed as shown in FIG.
A data pattern of a total of 11 bits including a level start bit 1 bit DO-D7 data bit, a parity bit 1 bit, and a level stop bit is transmitted. FIG. 15 is a diagram showing how each bit is sent,
One bit shown in (a) is finely modulated as shown in (b), and the modulated wave is transmitted via a coil as shown in (c). Then, the data is converted into digital data on the receiving side as shown in (d), and extracted as received data as shown in (e).

Is a switch circuit, and 13 is a demodulation circuit. The control circuit outputs a signal shown in FIG. 15 (b) according to the information signal. That is, when the information signal is at the "0" level, the 1 level and the 0 level are alternately repeated during the period, and when the information signal is at the "1" level, a signal that maintains the 1 level during the period is output. It has become.

The message specification is as follows. First, the basic message has a command-logical address-data sequence-message end-BCC configuration except for some messages from the main unit to the expansion card and some from the expansion card to the main unit. If there is no data string,
Alternatively, if the data length is fixed, message end and BC
C is omitted. The BCC is an exclusive OR of all data from the command to the message end.

[Effects of the Invention] As described above, according to the present invention, it is possible to display keys having an arbitrary size and an arbitrary key code in an arbitrary position by the required number of keys, which is convenient. It has the effect of. In addition, by dividing the display screen, key input can be confirmed only by searching a small range, the input coordinate signal can be converted to key code at high speed, and the repetitive processing part Since a general-purpose program can be used, there is an effect that the program size can be reduced.
