A backlight 17 for illuminating the transparent liquid crystal display plate 16 is installed adjacent to the liquid crystal display plate 16, as shown in FIGS. 5 and 6, and generates visible light of different wavelengths to illuminate the liquid crystal display plate 16. It has a plurality of light emitting devices 31 and 32 for illumination, and the plurality of light emitting devices 31 and 32 are alternately turned on by the control device 10. The light emitting device 31 is, for example, a green LED, and the light emitting device 32 is a red LED. When the PIN number is registered, the light emitting device 31, which is a red LED, lights up, and when the PIN number is cleared, the light emitting device 32, which is a green LED, lights up. However, both the light emitting devices 31 and 32 may be turned off.

The light emitting devices 31 and 32 are driven by the control device 10, and this operation will be explained with reference to FIG.

First, when the control device 10 is started, the control device 10 detects the state of the mode setting switch 24 (step 40), and when the mode setting switch 24 is in a predetermined state, it emits an unlocking output and locks the door. Unlock mechanism 7 (step 41). In this unlocked state, the password is cleared, the light emitting device 32, which is a green LED, is turned on (step 42) and the locker is on standby until the user uses the rental locker. Next, when the user operates the switch 3 and enters the password (step 43), the light emitting device 32, which is a green LED,
is turned off (step 44), and conversely, the light emitting device 31, which is a red LED, is turned on (step 45). This means that the rental car is in use. Next, the control device 10 determines whether the latch switch 25 is in the on state (step 46), and when the latch switch 25 is off, the red light LED of the light emitting device 31 continues to be lit (step 45).

However, when the handle 5 is rotated in step 46 and the latch switch 25 is turned on, the control device 10 generates a locking output and locks the locking mechanism 7 (step 47), and also turns on the light emitting device 31, which is a red LED. Turn off the light (step 48). At this time, the rod 35 protrudes upward, as shown in FIG. 4C. Next, when the user starts setting an unlock number (step 49), the red LED light emitting device 31 is turned on to indicate that the rental locker is in use (step 50). Next, the control device 10 determines whether the input of the reference number has been completed (step 51), and determines whether the input reference number matches the password stored in the storage means (step 52). .
If the input of the reference number is not completed in step 51, the process returns to step 50, and if the reference number and the password do not match in step 52, the process returns to step 48. If the reference number and password match in step 52, the control device 10
generates unlock output for a certain period of time (step
53) and return to step 46. At this time, the rod 35 retracts downward, as shown in FIG. 4B.

Next, in this invention, the operation of turning on and off the green light LED light emitting device 31 will be explained with reference to FIG. This operation can be performed between steps 41 and 42 of the flowchart shown in FIG. Of course, the operation of the light emitting device 31 is controlled by a command signal from the control device 10.

First, in step 60, the control device 10 determines whether the card 8 is inserted into the card insertion slot 9 or not. If any of the switches 3 is input while the card 8 is inserted into the card insertion slot 9, the process advances from step 61 to step 62. That is,
When there is any switch input, the control device 10 detects the signal and outputs a green light through the drive circuit 18.
The LED light emitting device 31 is turned on. Here, the control device 10 determines whether or not there is the next input to the switch 3 (step 63), and when the next switch input is applied, the required number of digits of the password, for example, a 4-digit number, is input. (Step 64).
If the four-digit number has not been entered, the process returns to steps 64 and 63.

If a four-digit number is input in step 64, it is determined whether or not a setting key switch provided as one of the switches 3 is pressed (step 65). If the setting key switch is pressed here, the solenoid 13 is driven, the lock mechanism 7 is locked or unlocked (step 66), and the backlight 17 is turned off. If there is no next switch input in step 63, the control device 10 remains in a standby state for a certain period of time, for example 15 seconds (step 63).
68) If the next switch input occurs within 15 seconds, the process proceeds from step 68 to steps 63 and 64. However, if there is no next switch input within 15 seconds at step 68, controller 10 turns off backlight 17 via drive circuit 18 and shifts controller 10 to the reset state.

The above embodiments of the invention can be modified. For example, as shown in FIG.
The light-emitting devices 31 and 32 may be arranged to illuminate the photoconductive material 36 from the side. Further, the sending device is not limited to green light, but can also use light of other colors such as white.

Effects of the invention In the lighting device for the LCD display of the keyless rental car of this invention, when any one of the switches is operated, the liquid crystal display panel is illuminated by the light emitting device, and when a certain period of time has elapsed after the start of illumination, or when a predetermined time is set by the switch. When the digit number has been memorized, the illumination of the liquid crystal display board is stopped and the code displayed on the liquid crystal display board is clearly shown to the user while the switch is operated. Therefore, even under insufficient indoor lighting, the liquid crystal display section can be clearly viewed. Furthermore, since the illumination of the liquid crystal display section is normally turned off, it is possible to save power.
