2 and the input detection unit 14. The audio processing unit 12 performs digital processing of the audio signal from the input terminal 10 according to the control of the main body control unit 16, supplies the digital signal to the recording / reproducing unit 18, performs multi-track recording on the magnetic tape mounted on the recording / reproducing unit 18, and The recording / reproducing unit 18 digitally processes the audio data reproduced from the magnetic tape, and outputs an audio signal from the output terminal 20.

The main body controller 16 controls on / off of the transistor Q1 to control the operation / stop of the fan motor 22 for driving the cooling fan, and also controls the transistor Q2.
Alternatively, by turning on Q3, the light emission luminance of the light emitting element P1 of the display unit 24 is variably controlled. When the transistor Q2 is normally turned on and the transistor Q3 is turned on at the time of dimming or extinguishment, the resistance values of the resistors R2 and R3 connected between the collectors of the transistors Q2 and Q3 and the light emitting element P1 are R2 <R3.

A remote control device (remote control) is connected to the DMTR by a wire harness.

Further, since the power saving mode of the electronic device can be controlled from the remote control device, the cooling fan can be forcibly stopped without going to the electronic device.

According to a third aspect of the present invention, there is provided a first power saving process for dimming or extinguishing a display unit of an electronic device, and a dimming or extinguishing process of a display unit of a remote control for remotely operating the electronic device. When executing the power saving mode including the three processes of the power saving process of No. 2 and the third power saving process of reducing or cutting off the power supply of the signal processing system, the cooling fan is stopped when the third power saving process is performed. By performing the processing, the drive control of the cooling fan is linked to the power saving mode of the electronic device, and the cooling fan is stopped when the signal processing system that is raising the temperature inside the housing is powered down, so the efficiency is reduced. In addition to being able to drive the cooling fan, the power consumption of the electronic device can be reduced.

According to the fourth aspect of the present invention, when cooperating with the remote control device is selected, the second power saving process is executed, so that power saving of the remote control device becomes possible.

According to the fifth aspect of the present invention, the third power saving process can be executed when there is no signal input to the signal processing system for a predetermined time or more.

According to a sixth aspect of the present invention, the specific key is assigned to the second key.
The third power saving process can be forcibly executed by operating continuously for a predetermined time or more.

According to a seventh aspect of the present invention, when co-operation with the remote control device is selected, the second power saving process is executed based on an instruction signal from the electronic device. Power saving becomes possible.

According to the eighth aspect of the present invention, the second power saving process is executed when cooperating with the remote control device is selected in all of the connected electronic devices. If the cooperative operation with the remote control device is not selected, the second power saving process is not performed, and the remote control device can control the electronic device for which the cooperative control is not selected without any trouble.

According to the ninth aspect of the present invention, the specific key is assigned to the first key.
When the operation is continuously performed for a predetermined time or more, the execution of the first power saving process is instructed, the second display unit is dimmed or turned off based on the predetermined execution condition by the instruction, and the specific key is operated for the second predetermined time When the operation is continued, the execution of the third power saving process is instructed, so that the power saving mode of the electronic device can be controlled from the remote control device. Therefore, the cooling fan is forcibly stopped without going to the electronic device. be able to.

According to the tenth aspect, when the co-operation with the remote control device is selected, the second display unit can be dimmed or extinguished.
