Specifically, the clock processing and the display processing are executed, and the time data and the date data input from the time counting circuit and the date counting circuit (not shown) are output to the display driving section 23 and displayed on the display section 13.
In addition, remote control processing is executed according to various remote control instruction signals input from the key input unit 12, various remote control code data is output to the transmission unit 22, and the LED 16 is caused to emit light to transmit the remote control code signal. Further, when the remote control code data signal emitted from the genuine remote control device attached to the electronic device is input through the light receiving unit 24, the remote control code data signal is stored in the RAM 28 for each electronic device to be transmitted.

Further, in a remote control process which will be described later, when the selection key for selecting an electronic device for remote control operation is operated, the CPU 21 reads out the selection sequence data corresponding to the time zone of the selection operation from the RAM 28 and The devices are selected according to the selection order.

A set time zone memory 36, a selection order data memory 37 that stores electronic equipment selection order data in the time zone set in the set time zone memory 36, and a data memory 38 that stores electronic equipment modes and remote control data corresponding thereto.
To form.

The above-mentioned direct return flag F is set to "1" when any key operation is performed in each mode, and when the mode key is operated in this state, a certain period of time is waited for. Instead, a direct return process for immediately returning to the display process is performed.

Next, the operation will be described.

First, the main processing of the CPU 21 in the wristwatch 1 will be described with reference to the flowchart shown in FIG.

In FIG. 4, when the battery of the wristwatch 1 is replaced and the supply of the drive voltage is started, step S10 is performed.
Whether or not there is a key input is determined in the 0 HALT (standby state). Here, when there is no key input, a pulse signal of a constant cycle created by the oscillation circuit 25 and the frequency dividing circuit 26 described above is output to the CPU 21, and the time counting circuit and the date counting circuit in the CPU 21 perform time counting processing. (Step S101).

Next, in step S102, if the remote control mode P is not "0", the number of clock pulses output from the frequency dividing circuit 26 is counted (step S10).
3), when the fixed time T has passed, the T timer 3 of the RAM 28
5 is reset (step S105), and the remote control mode P is set to "0" which is the time display mode (step S1).
06), time display processing is performed (step S107),
The process returns to the HALT (step S100).

In step S102, when the remote control mode P is "0", or in step S10.
When the constant time T has not elapsed in 4, the time is displayed as it is (step S107), and the process returns to the HALT (step S100).

If there is a key input in the HALT (standby state) in step S100, it is determined whether or not the remote control mode key is pressed (step S108). When the mode key is pressed and the direct return flag is F = 1, direct return processing is performed,
While setting the direct return flag F to "0",
The remote control mode P is set to "0" in the time display mode, time display processing is performed (step S107), and the HALT is performed.
It returns to (step S100).

When the mode key is pressed and the direct return flag is F ≠ 1, the remote control mode P is incremented and converted to the next mode (step S112). Here, it is determined whether or not the incremented remote control mode is P = 4 (step S11).
3). In this embodiment, the remote control modes are only 0 to 3, and when the mode number is exceeded, P = 4.

When P = 4, the remote control mode P is set to "0" (step S114), and the direct return flag F is set to "0" (step S11).
6), time display processing is performed (step S107), and the process returns to the HALT (step S100).

When P = 4 is not satisfied, the remote control modes P are 1 to 3 and the mode setting processing corresponding to each mode is performed (step S115). A subroutine of this mode setting process is shown in FIG.

In the mode setting process shown in FIG. 5, it is determined whether or not the current time and the set time stored in advance in the set time zone memory 36 of the RAM 28 match (step S200). In this embodiment, the set time zone is "9:00.
~ 17: 00 "and the current time is 10:00, for example, the current time matches the set time zone. For this reason,
The mode is switched according to the order of selecting the electronic devices corresponding to the set time (step S201). That is, as shown in FIG. 3, the set time zone “9: 00-1
During "7:00", the normal selection order is (TV: P =
1) → (video: P = 2) → (air conditioner: P = 3), then (air conditioner: P = 3) → (TV:
The setting is such that the order is changed from P = 1) to (video: P = 2).

If the current time and the set time do not match in step S200, the normal selection order (TV: P = 1) → (video: P = 2) → (air conditioner: P =
3) is applied, and mode selection corresponding to the remote control mode P is performed.

Again, returning to step S115 of FIG.
After the mode setting process, the direct return flag F is returned to "0" (step S116), the display process corresponding to each remote control mode P is performed (step S107),
The process returns to the HALT (step S100).

Further, in step S108,
If the mode key has not been pressed, it is determined whether or not the remote control data transmission key has been pressed (step S11).
7). If the remote control data transmission key is not pressed, other key processing is performed, and if the remote control data transmission key is pressed, in step S118, if the remote control mode P is not "0", that is, other than time display. In the case of the mode, the direct return flag is set to F = 1
Then, the remote control data corresponding to the key of the set mode is read from the RAM 28 and transmitted from the LED 16 (step S120). At the same time, the auto return timer T is set to "0" (step S121), a display process corresponding to each remote control mode P is performed (step S107), and the process returns to the HALT (step S100).

As described above, the remote control device according to the present embodiment is preliminarily set in the time zone so that the mode selection of a plurality of electronic devices for remote control operation can be performed in the order of high frequency of use according to the time zone. The mode selection order according to the time zone is set. Therefore, the mode selection order of the electronic devices is automatically switched according to the time zone in which the remote control is operated, and the mode selection can be performed in the order of the frequently used selection mode according to the time zone. Operability can be improved.

In the above embodiment, the selection mode order according to the time zone is set in advance, but by storing the frequency of use of the mode used in a certain time zone, the stored mode in the certain time zone is stored. The mode may be selected based on the frequency of use.

In the above embodiment, the case where the remote control device of the present invention is applied to a wristwatch is shown.
Not limited to this, the operability of the learning remote control device can be improved by applying it to the conventional learning remote control device.

[0045]

According to the remote control device of the present invention, the time zone management means manages the time zone in which the remote control operation is performed, and the control means uses the selection order storage means to select the time zone in the mode selection time. Since the device is read out and the remote control code of the selected device is generated from the device code generating means, the device to be the remote control target can be efficiently selected and the operability is improved.
