It has a good rate conversion function and a world clock.

[Conventional technology]

Conventional world clocks with a rate conversion function and good portability are disclosed in Japanese Patent Application Laid-open No. 53-55162 and Japanese Patent Application Laid-open No. 53-2706.
It is described in Publication No. 7 and Japanese Patent Application Laid-open No. 59-760. However, in both cases, the operation of the world clock was complicated, and the correlation between the rate value and the world clock was low.

[Problem that the invention seeks to solve]

Conventional world clock operations involve pressing one key repeatedly to move the city marks on the display in sequence and simultaneously displaying the current time of that city mark. It took many key operations to find out.

In addition, in conventional rate conversion, a key that can calculate the rate value of each country seven times is prepared for each rate value, and all that is required is to write the currency unit and country name in the key, so it has little relevance to the world clock. It was difficult to use because the relationship between cities and monetary units, and between cities and country names was not clear.

[Purpose of the invention]

The purpose of the present invention is to provide a rate conversion system with excellent portability and operability.
Our goal is to provide a world clock with m functions.

[Failure to solve the problem]

In order to solve the above problems, the present invention provides a city key for specifying each city or country in the world as a key input means, and displays the current time of the input city key on the display means in clock mode. time difference calculation processing means for processing as a time call input; and rate value display processing means for processing as a currency rate call input for displaying the currency rate value of the country of the input city key on the display means in the rate value display mode; In the rate conversion mode, a rate conversion processing means is newly provided for processing the currency unit of the country of the input city key on the display means as a currency unit call input.

[Effect]

With the above configuration, in the clock mode, the time difference calculation processing means calculates the current time of the input city key from the input city key and the time data storage section of the writable storage means, and the display means calculates the current time of the input city key. By displaying the current time in cities around the world, it is now possible to call up the current time in cities around the world with a single touch. Similarly, in the rate value display mode, the rate value display processing means displays on the display means the rate value set for the city input from the input city key and the rate value storage section of the writable storage means. It is now possible to directly recall and check the set rate value with one touch. Furthermore, in the rate conversion mode, the rate conversion processing means determines the input city key as a currency unit call input, and uses the numerical value inputted in advance using the numeric keys 0 to 9 and the rate value storage section of the writable storage means. By performing rate conversion and displaying the result on the display means, it has become possible to realize a rate conversion function with good operability.

When a key is input by the key input means 7, a key processing program stored in the ROM 4 is executed. In the key processing program, after first determining the foal of the key input (STEPI), mode data is read from the mode storage section in RAM 6, and its contents are set to the clock mode,
If the mode is rate display mode or rate conversion mode, the process branches to time difference calculation processing, rate value display processing, and rate conversion processing (STEP 2), and the respective processing is executed (STEPs 3 to 5).

FIG. 6 is an operational flowchart of the time difference calculation process of the present invention. This process is executed when there is a key input while in watch mode. The type of key input by the key input means 7 is determined and each process is executed (STE
P30~3? ). If the input key is a city key (STEP 30), calculate the time difference between the input city and the reference city (STEP 35), calculate and display the current time of the input city in addition to the time data of the reference city. At this time, the time difference data corresponding to the city is stored in the ROMd (STEP 35).
), the time data of the reference city is stored in the RAM 4 (STEP 36).

If the input key is the MODE key (STEP
31) Perform mode change processing (STEP 37)
. In the mode change process (STEP 37), the mode data in the RAM 6 is rewritten, and if the next mode is, for example, a rate value display mode, the data in the rate value storage section 61 in the RAM d is used as display data. If the input key is the LOCK key (STEP 32), time adjustment processing is performed (STEP 33).

FIG. 7 is an operational flowchart of rate value display processing. This process is executed when a key input is made in the rate value display mode. The type of key input by the key input means 7 is determined and each process is executed (
STEP 40-42). If the input key is a city key (STEP 40), the currency rate value used in the country of the input city is read out from the rate value storage section 61 in the RAM 6 and displayed as data (5TEP 45).

7). The rate conversion process (STEP 56) multiplies the value displayed on the display means 7 at the time the city key is input by the currency rate value of the input city key, or divides the displayed value by the currency rate value. For example, if the standard currency is ¥, and the displayed value is converted to ¥ as the foreign currency of the input city key, the following will be done.

AC, 5, ; Key groan 650 yen and display AC, 3
,"-'s key groan 720 yen and display AC, 2, bug's
If the key displayed as key 160Y is an arithmetic operation key or a numeric key (STEP 51, 52),
Perform the same processing as a normal calculator (STEP 58-60)
, the results are displayed on the display means 7 (STEP 55).

If the input key is the MODE key (STEP
53) Perform mode change processing (STEP 54)
.

It is also possible to create a highly versatile rate converter by performing the calculation process as follows. After entering the numerical value, the first city key entered works as the currency unit input, and the currency is converted to the second entered city key. It will look like this:

AC, 12, - key - 612g and display - 0 sake] 1
91 group 1 destination 2 → 36 DM is displayed This can be done by multiplying the displayed value by the rate value of the city key entered first and dividing by the rate value of the city key entered second. It is.
