A timer 113 for outputting a drive signal for upward driving between the controller and an upward outside mirror driving motor for moving the outside mirror to a predetermined upward position according to the upward outside mirror driving signal output from the timer 113 ( 114).

Referring to the operation and effect of the present invention configured as described above are as follows.

First, when the driver puts in the reverse gear to reverse the vehicle, the reverse gear switch 101 is ON.

Then, the relay 102 outputs an ignition signal, that is, a high signal to the NOR gate 103 by turning on the reverse gear switch 101.

Then, the NOR gate 103 outputs a low signal by ORing the signal output from the relay 104.

On the other hand, the NAND gate 104 combines the ignition signal and the signal output from the second R / S flip-flop 106 to negate the logic sum, that is, the high signal, to the first R / S flip-flop 106. Will print).

At this time, the first R / S flip-flop 106 is driven by the low signal output from the NOR gate 103 so that the high signal output from the NAND gate 104 is applied to the S input terminal. The low signal is inputted to the R input terminal by phase inversion by a NOT gate 105.

Then, the first R / S flip-flop 106 combines the signals applied to the two input terminals and outputs a high signal to the Qn output terminal.

Accordingly, the operational amplifier 109 amplifies the high signal output from the first R / S flip-flop 106 to a predetermined level and outputs it to the timer 110.

Then, the timer 108 outputs a drive signal for driving the outside mirror downward for a predetermined time to the downward outside mirror 111 by the signal output from the operational amplifier 107.

Accordingly, the downward outer mirror driving motor 109 moves the outer mirror to a predetermined downward position by the downward outer mirror driving signal output from the timer 108.

As a result, when the vehicle reverses, the outside mirror is adjusted in a downward direction (for example, about 10 °) to help secure the rear view.

On the other hand, when the driver removes the reverse gear, that is, when the reverse gear switch 101 is turned off, the relay 102 outputs a low 0 signal to two input terminals of the NOR gate 103.

Then, the NOR gate 103 combines the signal output from the relay 102 to output a high signal.

Thus, the first R / S flip-flop 106 is not driven and only the second R / S flip-flop 108 is driven.

Accordingly, the high signal output from the first R / S flip-flop 106 is input to the S input terminal and the second NOT gate 107 to the R input terminal. Phase inverted by), and the low signal is inputted.

Then, the second R / S flip-flop 108 combines the signals applied to the two input terminals and outputs a high signal to the Qn output terminal.

Accordingly, the operational amplifier 112 amplifies the high signal output from the second R / S flip-flop 108 to a predetermined level and outputs it to the timer 113.

Then, the timer 113 outputs a drive signal for upward driving of the outside mirror for a predetermined time to the upward outside mirror driving motor 114 by the signal output from the operational amplifier 112.

Accordingly, the upward outer mirror driving motor 114 moves the outer mirror to an upward predetermined position by the upward outer mirror driving signal output from the timer 108 to return the outer mirror to the original position. Will be.

As described above, the present invention has the effect of preventing damage to the vehicle due to annihilating protrusions when reversing, since the position of the outside mirror is automatically adjusted when reversing, thereby securing more rear view.
