Microprocessor parking meter internally held in a car
First Claim
1. A microprocessor parking meter as internally held in a car comprising:
- a casing;
a control key means formed on a lower portion of said casing having a plurality of area selector keys for selecting plural different parking areas, a start key for starting a timing operation of said microprocessor parking meter, and a stop key for stopping the time operation of the parking meter;
a display means formed on an upper portion of said casing having a plurality of digits indicating a parking status and real time which includes a first digit for parking area display, a second, third and fourth digit for a parking-unit display, a decimal-point of the fourth digit for showing parking-at-present, and a time indicating display with the fifth, sixth, seventh and eighth digit showing a real clock time;
a microprocessor means operatively manipulating said display means as actuated by said control key means for showing and sequentially degrading or reducing preset parking units each unit corresponding to a parking time interval with respect to a selected parking area among the different parking areas during a lapse of parking time; and
a trigger means having a trigger-out connector and a trigger-in connector respectively formed on two opposite sides of said casing and electrically connected with said microprocessor means, having a connection cord operatively connecting a trigger-out connector of a first parking meter to a trigger-in connector of a second parking meter for continuously actuating the second meter when the first meter is finished.
