In step R16, it is determined whether or not “HH: MM + 60” is the current time. If NO, the process moves to step R7, and if YES, the process moves to step R17. In step R17, the current time “HH: MM” is stored in the RAM, and the process proceeds to step R13. In step R18, it is determined whether or not “HH: MM + 45” is the current time. If NO, the process moves to step R7, and if YES, the process moves to step R17.

  More specifically, in this example, in the power-on mode, audio source information, current time, and the like are always displayed on the display unit 4. In some cases, the current time is not always displayed. In the standby mode, the display period of the current time on the display unit 4 is determined as follows.

(1) Generally, the user is often asleep between midnight and 6am or 7am, and at other times the user may be awake and active. It is thought that there are many.
(2) In consideration of the above circumstances and to improve the time separation, first, the first day of the period from midnight to 12:00 am and the first time from 0:00 pm to 12:00 pm Divide into 2 hours.
(3) Generally, the sleep cycle consisting of human non-REM sleep and REM sleep is about 90 minutes, and it is considered that sleep becomes shallow every 90 minutes. In the case of waking up, it is considered preferable to set the display period of the current time on the display unit 4 to 90 minutes after going to bed again.
(4) When a user is awake and is acting, it is generally considered that there are many cases where the user acts with a basic unit of one hour.
(5) Considering the above (1) to (3), in this example, the current time is not always displayed on the display unit 4, and basically, in the first time zone from midnight to 12:00 am. In the standby mode (note that not only the standby mode but also the power-on mode may be included), the display period of the current time on the display unit 4 is set to 60 minutes and the current time of the display unit 4 is displayed. The current time is displayed on the display unit 4 from 30 minutes before the user's sleep becomes shallow.
(6) In consideration of (1), (2) and (4) above, in the second time zone from midnight (12:00 am) to midnight, during standby mode (only in standby mode) In some cases, the power-on mode is also included.) The display period of the current time on the display unit 4 is 45 minutes, and the display time of the current time on the display unit 4 is 30 minutes. The current time is displayed on the display unit 4 for 30 minutes from 15 minutes before the beginning of the basic unit time (1 hour).
(7) As described above, in the standby mode, the current time is displayed on the display unit 4 only for the time that is considered necessary for the user. I am trying not to. One day may be divided into three or more time zones.

  Even when the current time is not displayed on the display unit 4, the current time is displayed on the display unit 4 for 30 minutes by pressing the clock call key 7 so that the user does not feel inconvenient. The display cycle is measured by the microcomputer 2 after the end of the display so as to correspond to the life rhythm (life pattern) of each user.

  When the user sets a timer using the timer operation unit 8, it is considered that the user wakes up at the timer setting time. In this case, considering the human sleep cycle, it is considered that the user's sleep is shallow 1 hour 30 minutes before the timer set time. Therefore, the current time is displayed on the display unit 4 for 30 minutes from 1 hour and 30 minutes before the timer setting time, so as to correspond to the life rhythm of the user.

  When the user sets sleep by using the sleep operation unit 9, the user wants to go to bed. Therefore, the current time is not displayed on the display unit 4 in any time zone of the first and second time zones. Electricity is being planned. Even in this case, when the timer setting time comes or when the user wakes up and enters the power-on mode, the current time is displayed on the display unit 4, so that the user does not feel inconvenience. .

  In the above embodiment, the present invention is applied to an audio device, but the present invention is also applicable to other audio / visual devices. In the claims and specifications of this case, “/” used in audio / visual devices, recording / playback units, etc. means “and / or”. For example, an audio / visual device means a device that can perform reproduction and recording of either an audio source or a visual source, or one of reproduction and recording. Note that this is displayed on the display means when the visual source is reproduced.
