Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic counter device used for a traffic volume survey, a passenger survey, etc.

[0002]

2. Description of the Related Art Conventionally, this type of counter device is mainly a mechanical counter, and when a manipulation key is pressed, a number is displayed on a count display portion via a gear, and a carry mechanism combining gears is used. The digits are sequentially carried by and counted.

[0003]

However, in the above-mentioned conventional mechanical counter device, since the counted number is simply displayed, for example, in the case of a traffic volume survey, only the total number of one day can be known, and it is determined by time zone. When investigating the traffic volume of, there was a problem that the numerical value had to be recorded each time the time zone changed.

The present invention is intended to solve such a conventional problem, and an object of the present invention is to provide an excellent electronic counter device capable of easily measuring the change in the quantity for each set time zone.

[0005]

In order to achieve the above object, the present invention provides an operation key for counting the quantity,
A clock IC for notifying the time, a memory for storing the counted numerical values, a display means for displaying the counted numerical values, a count of the number of times the operation keys are pressed, and the result is displayed on the display means. A CPU that stores the numerical value of a certain time zone in the memory based on the time signal from the clock IC
It is provided with.

[0006]

Therefore, according to the present invention, the CPU causes the clock I
Since the count value of a certain time zone is stored in the memory based on the time signal from C, the transition of the quantity for each time zone can be easily measured.

FIG. 1 shows the appearance of an electronic counter device according to an embodiment of the present invention. In FIG. 1, 11
Is an operation key for counting, and this operation key 1
When 1 is pressed, +1 is added to the count value of the liquid crystal display 12 provided above each operation key 11 and displayed. Reference numeral 13 is a communication interface connector for transferring the data of the electronic counter device to an external terminal of a host system.

FIG. 2 is a schematic block diagram of the electronic counter device in this embodiment. In FIG. 2, reference numeral 21 is a CP that controls the entire apparatus by counting the number of times the operation keys are pressed.
U and 22 are clock ICs 23 for notifying the time to the CPU 21,
Is a memory for storing the counted numerical values, and has a total numerical value storage area 23a and a time zone numerical value storage area 23b. Two
Reference numerals 4 to 27 are key switches corresponding to the operation keys 11 in FIG. 1, 28 to 31 are liquid crystal display circuits including the liquid crystal display 12 in FIG. 1, and 32 is a communication interface connector 13 in FIG. It is a communication interface. Reference numeral 33 is a totaling condition setting circuit for arbitrarily setting the time and width of the time zone. 34 is a printer interface for connecting a printer (not shown),
Reference numeral 35 is a memory card interface for connecting a memory card (not shown).

Next, the operation of the above embodiment will be described.
In FIG. 2, the operator uses the counting condition setting circuit 33 to
For example, a time zone is set every hour from midnight to midnight the next day. The CPU 21 reads this setting information when the power is turned on and monitors the time signal from the clock IC 22. When the operator presses any one of the key switches 24-27, the CPU 21 determines which one of the key switches 24-27 is pressed, and the liquid crystal display circuits 28-31.
Each time the key switch is pressed, +1 is added to the liquid crystal display circuit corresponding to the pressed key switch to display a number. At the same time, the total numerical value storage area 23 of the memory 23
Add +1 to the value of a. In this manner, the number of times each key switch is pressed is counted and stored in the memory 23, and the numerical value is displayed each time the display circuits 28 to 31 are connected.
To be displayed. In the meantime, the CPU 21 determines the memory 23 based on the time signal sent from the clock IC 22 on a regular basis.
Value of the total numerical value accumulation area 23a of time zone numerical value accumulation area 2
Copy to 3b. That is, when the time zone is set every hour, as shown in FIG.
Value of the total numerical value storage area 23a of the time zone numerical value storage area 2
In 3b, the data is separately stored every hour. This allows
It will be possible to collect the total for each set time period.

Thus, according to the above embodiment, the CPU
21 counts the number of times the key switches 24 to 27 are pressed, stores the numerical value in the total numerical value storage area 23a of the memory 23 each time, and based on the time signal from the clock IC 22, the total numerical value. Is accumulated in the time zone numerical value accumulation area 23b, the total quantity for one day can be counted and the quantity for each time zone can be totaled.

In the above embodiment, the totalizing condition setting circuit 3
By setting various counting conditions in 3, various applications can be dealt with. The configuration can be simplified by using a dip switch or the like as the totalization condition setting circuit 33. Alternatively, the setting condition can be input from the memory card by inserting the memory card in which the totaling condition is set in advance into the memory card interface 35. Further, the data stored in the memory 23 can be transferred to another higher-level external terminal through the communication interface 32, and the time for creating a report or the like can be saved. Further, it is possible to insert a memory card into the memory card interface 35 and draw out data from the memory card. Furthermore, by connecting a printer to the printer interface 34 and printing the data in the memory 23 on the spot, it is possible to confirm the state of the quantity change on the spot.

In the above embodiment, the CPU 21 and the clock IC 2 are
Although the memory 2 and the memory 23 are configured separately, they may be configured as a one-chip IC on the same chip. Further, it goes without saying that the numbers of the key switches 24 to 27 and the liquid crystal display circuits 28 to 31 can be increased or decreased as necessary. Further, the clock IC may be replaced with a CR circuit as long as it can measure a certain time.
