Abstract

PROBLEM TO BE SOLVED: To provide an electronic time recorder, with which the disorder of a clock is automatically corrected. SOLUTION: This time recorder is provided with a receiving control part 3 for periodically executing the receiving operation of a standard time radio wave. When the standard time radio wave is successfully received, the receiving control part 3 corrects the present time of a clock part 2 on the basis of the time data of the standard time radio wave.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a time clock, and more particularly to a time clock in which a clock error is automatically corrected.

[0002]

In a conventional electronic time clock, it is inevitable that a certain amount of error occurs in a built-in clock, so that it is necessary to check and correct the clock error on a daily basis.

[0003] Therefore, there is a technical problem to be solved in order to reduce the time and labor for managing the clock of the time recorder, and the present invention aims to solve the above problem.

[0004]

SUMMARY OF THE INVENTION The present invention proposes to achieve the above object, and comprises a timepiece, a card printing device and a printing control device, and a time card inserted into a card insertion slot of a time recorder. In the time recorder that detects and prints the time at the time of insertion into the time card, a reception control unit that periodically executes the reception operation of the standard time radio wave is provided, and based on the time data of the standard time radio wave when the reception of the standard time radio wave is successful. And a control unit for automatically calibrating the current time of the clock.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a block diagram of a time clock. A timepiece 1 includes a clock unit 2 and a reception control unit 3, 4 is an I / O, 5 is a CPU, 6 is a ROM, and 7 is a RAM.

[0006] The CPU 5 controls the clock section 2 of the clock 1 through the I / O 4
The time data is sequentially read, and the time display unit 8 is driven to display the time. When a time card is inserted into the card slot of the time recorder, the CPU 5 drives the card feed mechanism 9 to pull in the time card, read the personal ID number of the time card, and read the date field of the time card corresponding to the current date. Sends a time card until the position coincides with the position of the printer head 10, and prints the current time in the clock time column or clock out time column.

[0007] The printed time data is written and stored in a personalized data table of the RAM 7, and the administrator can read out and print out the working time total data at any time as in the conventional time clock. .

The timepiece 1 has a function of receiving a standard time radio wave (JJY) by the reception control unit 3 and a function of correcting the clock unit 2 in the same manner as a general radio timepiece. Switching between the date and time correction mode and the reception time setting mode can be performed, and the adjustment button 12 is used to set the current time and the reception time.

[0009] The ROM 6 includes a regular reception schedule program for executing a standard time radio wave reception operation every hour.
A program for executing reception at an arbitrarily set time is stored, and the CPU 5 controls the clock 1 based on a regular reception schedule program or an arbitrary reception execution program.

FIG. 2 shows the flow of clock control of the time recorder. When the power cord of the time recorder is connected to an AC outlet, the time recorder is energized and the CPU 5 reads time data from the clock unit 2 of the clock 1.

If the reception time has not been set manually,
At regular time (once an hour) according to the regular reception schedule, the receiver enters the reception mode and tries to receive the standard time radio wave (step 1 → 2 → 4). If the reception fails at this time, the next regular reception time The receiving operation is executed again (step 5 → 1). When reception is successful, the clock section 2
Is calibrated (step 6) and the process returns to step 1.

If the reception time is set manually, the reception mode is entered at the time set manually (step 1).
→ 3 → 4), try to receive the standard time radio wave. Therefore, if the reception time is manually set at midnight or early morning, the reception control unit 3 does not enter the reception operation during the working hours, and the time is not corrected during the working hours. There is no difference from the above working hours data.

FIG. 3 shows another embodiment of the clock control, in which a reception operation stop mode is automatically entered during working hours. First, after the date is updated (not necessarily at midnight, but set according to the work style), until the first time card of the day is stamped, the regular scheduled reception schedule program will be used. once)
Then, the receiver enters the reception mode and tries to receive the standard time radio wave (steps 1 → 4 → 5). At this time, if the reception fails, the reception operation is performed again at the next regular reception time (step
6 → 1) If the reception is successful, the time of the clock unit 2 is calibrated (steps 6 → 7) and the process returns to step 1.

When the first time card of the day is inserted into the time clock and stamping is performed, the process proceeds from step 1 to step 2 to stop the receiving operation. And a time card stamping the time of attendance on the day (known from the attendance data in RAM7)
Until the time of leaving the office is stamped on all of them, that is, until all the workers at that sunrise have left, the reception operation continues to be stopped, and after everyone leaves the office, go to step 3 to step 4 and enter the regular reception mode, the first day of the next day, Attempt to receive the standard time radio wave until the time card is inserted into the time clock.

Therefore, similarly to the clock control routine of FIG. 2, the reception control unit 3 does not enter the receiving operation during the working hours, but corrects the time outside the working hours. There is no difference from the time data.

Although not shown, as another embodiment, the CPU 5 reads the earliest clock data and the latest clock data among the past clock data stored in the RAM 7 of the time clock. Alternatively, the reception schedule program may be configured to automatically enter the regular reception mode only between the time of leaving the work and the time of arrival.

The calibration time at the time of successful reception is displayed on the display panel of the time clock so that the calibration history can be confirmed. Further, the calibration time may be printed on a time card.

Although the time clock of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible within the technical scope of the present invention. It goes without saying that it extends to what has been done.

[0019]

As described above, since the time clock of the present invention automatically calibrates the time of the clock based on the standard time radio wave, it is possible to prevent the occurrence of errors in the working time data due to the wrapping of the clock. This eliminates the need to check and correct the clock error on a daily basis, thereby reducing the time and labor required for clock management.
