, locks and unlocks the door 4, etc. To lock/unlock the vehicle doors, etc., when the transmitter 1 is inserted into the slot machine 3a, a unique key code stored in the ROM inside the transmitter 1 is sent to the receiver 2 on the door side. The unique key code is compared with the registration code pre-stored in the ROM in the receiver 2 on the door side, and if the two match, the opening/closing body is automatically locked or unlocked according to the locked state of the vehicle opening/closing body. It's like it's going to happen.

In addition to this mechanism, this device also uses the RA in the receiver 2 on the vehicle body side.
Transmitter 1 transmits the lock status of opening/closing objects such as doors stored in M.
By transmitting this information to the side and storing it in the RAM of one example of the transmitter, it is possible to selectively lock and unlock opening/closing bodies such as vehicle doors and trunks. In addition to the above-mentioned mechanism, this device further includes a RAM in the receiver 2 on the vehicle body side.
If the driver forgets to apply the brake, door ajar warning, or forgets to close the trunk, etc., the driver forgets to apply the brake, door ajar warning, or forgets to close the trunk. When the transmitter 1 is removed from the vehicle body, the forgetting warning information is displayed on the transmitter 1. Third
As shown in Figure 4, there is an LCD on the surface of the transmitter l that displays the locked/unlocked status of opening/closing objects such as vehicle doors and trunks, and warning information such as forgetting to turn off the lights on the vehicle side.
A display section 5 using
Scroll switch9. lO is provided. The numerical switch 6.7.8 switches from automatic mode to manual mode when selectively locking/unlocking vehicle doors, etc., and when forgetting warning information on the vehicle body side is displayed on the display. This is used both when switching from to automatic mode. The scroll switches 9 and 10 scroll the information displayed on the display section 5 of the transmitter 1 in the manual mode state.
This is used to advance one item at a time; scroll switch 9 is used for forward advance, and scroll switch 10 is used for backward advance.

As shown in FIGS. 3 and 4, on the upper surface of the transmitter 1,
Three magnetic heads 12, 13, 14 are provided, and when the transmitter 1 is inserted into the slot 3a, the three magnetic heads 15, 16 .

shows.

Next, the operation of this apparatus will be explained according to the Pronk diagram in FIG. 5 and the processing flow diagram in FIG. 6.

In FIG. 5, 1 indicates the transmitter side and 2 indicates the receiver side. When the transmitter 1 is inserted into the slot 3a provided in the driver's side door 4 of the automobile, the transmitter 1 is stored in the ROM 18 in advance. The key code is magnetic head 14. It is transmitted to the receiver 2 side via IT.

At this time, the receiver 2 side receives the key code and compares and verifies the key code with a registration code stored in advance in the ROM 19 of the two receivers. As a result of the comparison, if the two codes match, a code matching signal is sent from the receiver 2 side to the transmitter 1 side, the buzzer in the transmitter 1 sounds, and the vehicle is activated depending on the locked state of the vehicle opening/closing body. The opening/closing body is automatically locked/unlocked. Furthermore, the locked state of the vehicle opening/closing body is displayed on the display unit 5 of the transmitter 1. Here, automatic locking/unlocking 5 is performed according to the door lock status on the driver side (driver side) and assist side (passenger seat side).The results are displayed on the display unit 5 of the transmitter 1, and the buzzer sounds. The relationship is as shown in the table below (marks in parentheses in the table indicate locations where the operation occurred).
