Further, the corresponding relation between the keys and data is charged between 1:1 and many:1 in the data input mode according to the contents of the data.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an input 1 display of a digital display electronic timepiece. [Prior Art] Conventionally, the input device of a timepiece has been the front side of the main body.

It was common for one to four buttons and knobs to be placed on the sides and back. Furthermore, digital watches, which have become popular as information devices in recent years, require a large number of buttons, and watches with 10 to 15 buttons are already known.

Furthermore, in Japanese Utility Model Application Publication No. 5B-88740, a touch switch is used as a new input device in a watch.

[Problem that the invention seeks to solve]

However, in the prior art, the input section was fixed and required a dedicated space.

Therefore, if the number of input buttons is increased, the operability deteriorates, and if the number of buttons is limited, a large amount of data cannot be input.

The present invention solves these problems,
The purpose is to provide a digital clock that allows a large number of input keys to be set in a limited space without sacrificing the display area, and that is easy to operate.

[Failure to solve the problem]

As shown in FIG. 1, the digital display electronic timepiece of the present invention comprises an optical display section 1 having a dot matrix configuration, a data input section 2 consisting of a plurality of transparent keys, and a data processing means 3 for processing input data. The data input section is located on the optical display section, and the optical display section has a data display mode in which characters are displayed in a position unrelated to the transparent key, and a data input section that requires data input. It has two modes: a data input mode in which characters are displayed at positions corresponding to each transparent key, and the data processing means can switch between these two modes. , is characterized in that the correspondence between keys and data changes to one-to-one or many-to-one correspondence depending on the content of input data.

〔Example〕

An embodiment of the digital display electronic timepiece of the present invention will be shown below.

Figure 2 is an external view. In the figure, numeral 4 denotes a liquid crystal display section with a dot matrix structure, the number of dots is 42 x 52, and characters can be displayed at any location.

In the figure, 5a to 5w indicated by broken lines are transparent key manual parts arranged on the display cover glass, and the user can input data by touching the keys. As for the lake, 58~5w, it is placed on the partition board.
Mainly used as a fixed key for clock control.

FIG. 3 is a sectional view showing the relationship between the transparent key and the liquid crystal panel. A data input section is arranged on the panel 5, which is made up of two glass panels having different thicknesses and having transparent electrodes 6 wired thereon. There is a spacer 9 between the two pieces of glass 7.8, which are normally kept apart. When touched with a finger from above, the thin glass on the upper side bends and a key is input.

FIG. 4 shows an example of use. Normally, the time is displayed as shown in Figure (a). This figure shows 12:34:56 a.m. on Sunday, January 1st.

In this way, a display state that does not require data input will be referred to as a data display mode. By touching the transparent key at the position where rMoDzJ is printed a predetermined number of times in the state shown in FIG. 3(a), the display changes as shown in FIG.

(b) Figure (-!, This mode specifies whether alarms and time signals are valid or invalid, and data can be input. This display state in which data can be input is called data input mode. (b) In the figure, 1
The row shows the alarm time, with 1- indicating 7:58 p.m.

Regarding "Kokoro, River, *" displayed in the second and subsequent rows, "Kokoro" is the alarm valid symbol, [1llj is the time signal valid symbol, and "*" is the alarm and time signal invalid symbol. is enabled and the time signal is disabled. The displays on the third and fourth rows represent the features of the present invention. This part is used to input whether to enable or disable alarms and time signals, but as shown in this figure, "ooNOFJ, rllll aN OFJ" is displayed to match the location where the transparent key is placed. .When comparing the character positions in the 1st and 2nd rows, the difference in position becomes clear.In the 5th and 4th rows, "0"1N"
If you touch any of them, "valid" data will be input, and "
If you touch either "O" or "1F", "invalid" data will be input.

In figure (b), when you touch the "c" key, the display changes to figure (c). (3) In the figure, the alarm time can be adjusted to morning or afternoon. Here too, the characters "AM PMJ" in the fourth row are displayed in the position corresponding to the transparent key.To specify the morning, press "A"
1M" key, and to specify the afternoon, touch either "P" or "M".

(C> In the figure, by touching the "self" key, the display changes as shown in the figure (d). In the case of (C), the alarm time can be adjusted. The difference from Figure 7 (b) and (C) is that in Figure (b), the two keys rojrRJ correspond to one data "valid", and the two keys "O" and "F" correspond to "valid". One data corresponded to multiple keys, just as it corresponded to the data "invalid".(C) As shown in the figure, [AJrMJ is "AM".

rr+jr+J corresponds to the data "afternoon" (7).

(d) Are you good at drawings? In this case, the only data that corresponds to the data "7" is the key in the corresponding position, and "1 to 9".
The same applies to

As described above, one feature of the present invention is to change the key combination depending on the type of data.

The features of the present invention have been shown above using usage examples, but the fifth
The figure shows a block diagram of the present invention. When data processing for controlling the clock is performed in the PU 10, the f1 mode is selected at the same time.

C! A key scan signal is output from the PUIO to the output port 11 and the key matrix 12, and a key response signal is input to the input port 13.

The CPU 10 checks the key response signal, performs data processing, and at the same time determines whether or not to switch modes. Therefore, when changing the display, the data to be displayed next and the display position data are read out from the ROM 13 or I'tAM 14 with reference to the mode determination result, and the display dry/l! IJ: feed, display on dot matrix display section 16.

The ROM 13 stores a control program for the entire watch and character data, and can be read out as needed. The RAM 14 stores changing data such as alarm times, and can be read and written as necessary.

The timekeeping section 17fds performs timekeeping, which is the function of a clock, and when displaying the time, the data of this timekeeping section 17 is read out by the 0PU10 and displayed.

Next, a flowchart regarding the above operation is shown in FIG.

If there is any key input in the mouth display state, the control program of the procedure shown in the flowchart of FIG. 6 stored in the ROM 13 is executed.After determining the input key, data is Determine the data input mode that requires input, or the display mode that changes only the data display. (Step 18) If the display mode is selected, the data input to the input key is displayed. and ends the execution of this program. (Step 19 → 24) In the data input mode, change the display and wait for data input. When data is input f'L, the corresponding process is executed. After that, it is determined whether the processing power S has been completed or not. If it is, the execution ends there. (Steps 19 → 20 → 21 → 22 → 26 → 24) To continue processing, further data input is required. Wait. (Step 26 → 20) In addition to this, a function to forcibly terminate data processing is added. (Step 21 →
24) The embodiment of the present invention is controlled by the above operations.

〔effect〕

From the above explanation, the effects of the present invention are that by arranging the key force above the data display section and making the display section and the key force section both function, a dedicated space for the keys is no longer required and the size is reduced. The design is also cleaner. Furthermore, since a display appears below the transparent keys, the positions of the keys can be easily recognized even when many transparent keys are crowded together.

Since the keys are combined according to the type of data, the area of the keys is expanded, making input much easier.

Another possible effect is that by changing the displayed content, unlimited data input can be made with a small number of keys.
