1. A simple and portable parking meter comprising:
- a main device for reckoning fees and at least one sub-device insertable into a plurality of slots on said main device, there being one or more sub-devices issued to a person parking his vehicle in an area to be monitored by the main device, the person being able to use a second of the sub-devices when a first of said sub-devices does not by itself have sufficient authorization capacity to allow of the parking area, the use of the second sub-device ensuring that no violation is charged to the person parking his vehicle;
whereinsaid main device has a CPU to which are connected peripherally an electric power loop, a reset loop, a keyboard loop, an oscillating loop, two or more card interface loops, and an LCD loop,said CPU performing the functions of fee reckoning and timing through the coordination of the above listed elements, providing said LCD with a displaying signal, and transmitting a signal for deducting charges from said sub-devices via the card interface loops,said electric power loop being used for turning on and off the power, the power loop being activated by a power key on a front panel of said main device,said reset loop adjusting the rate of charges and setting a predetermined parking time in cooperation with a setting key located on the front panel of said main device,said keyboard loop including said power key, said setting key, and actuating key, and a time reckoning key to control functions including turning on and off the power, determining the rates of charges and calculating the amount of parking time, and actuating and choosing the mode of charge reckoning,said oscillating loop providing said CPU with oscillation reckoning functions;
said card interface loops being connected to said slots in said main device so as to communicate with said sub-devices; and
whereinmessages displayed by said LCD loop including parking time, the rate of charges, balance remaining on a sub-device, fee based on the time parked, and low power warning.

Abstract
A portable parking meter including a main device and at least a sub-device; The body of the main device has two inserting slots for some sub-devices and is provided on the front face thereof with a control panel, the inserting slots are provided with some card interfaces capable of communicational connection with the main device when the sub-devices insert therein; The main device has a CPU which uses a reset loop connected peripherally with a keyboard interface, an oscillating loop and a LCD loop, and which has its internal timing program to establish the communication between it and the sub-devices, and it can count sequentially by the rate of value preset in the sub-devices for timing or reckonning times and deducting amount of charges in the sub-devices as a parking fee.
