Description

DETAILED DESCRIPTION OF THE INVENTION (a) Technical Field of the Invention The present invention relates to a time recorder for attendance management, and particularly to an improvement in the control portion of the time registration operation thereof.

(b) Background of the Technology To register the times of coming to work, leaving work, etc., a method of stamping the time on a time card using, for example, a time recorder is generally used.

(c) Problems to be solved by the conventional technology and the invention In this type of conventional time recorder, the time itself is stamped, but the time required for each person to register the time is relatively long. Therefore, when many stampers gather at the same time, there will be a large time difference between the registered times of these stampers.
If this is used as is for attendance management, inconveniences may occur. For example, even though the employee came to work before the starting time, many people who clocked in at the same time may cause the inconvenience that those who clocked in later in the order end up being late. Therefore, conventionally, when the above-mentioned situation occurs, there is an inefficiency in that the time registered by the time recorder must be corrected later, and a solution to this problem has been desired.

To this end, if the actual time stamps are different due to a concentration of time stampers, it may be possible to register the same time on the time card for all of them. However, conventional time recorders do not have a means for detecting a concentration of time stampers. Furthermore, since the purpose of the time recorder is to accurately register the actual stamped time on the time card, the stamped time has been controlled by the master timer of the time card. In order to stamp a time on a time card that is different from the actual stamped time, it is necessary to stop the advance of only the stamped time independently of the master timer. This was difficult because it went against the purpose of

To provide a time recorder capable of detecting a concentration of time stampers and stopping the advance of the time stamp independently of a master timer only during that time, thereby eliminating the inconvenience that occurs when a large number of time stampers are present. The purpose is to

(d) Means for Solving Problems The time recorder of the present invention includes a first timer means for outputting the current time, and a second timer means for updating the contents with the current time output from the first timer means. A second timer means and a predetermined card can be inserted, and when the card is inserted, the contents of the second timer means are recorded on the card or other recording medium, and a predetermined flag is set each time the card is inserted. a card input and recording means for outputting the flag, and a time interval at which the card is inserted into the card input and recording means based on a time interval at which the flag is outputted from the card input and recording means, and a time interval at which the card is inserted into the card input and recording means; The present invention is characterized by comprising a timer control means for suspending updating of the contents of the second timer means when the time width is shorter than a predetermined time width.

Note that the card input and recording means does not necessarily have to be one that stamps the time on the card itself, such as a time card, but can record the contents of the second timer means when the card is inserted in some form. It is fine as long as it is something.

(e) Effect The timer control means determines whether there is a concentration of stampers based on whether the time interval between card input and card insertion into the recording means (i.e., the time interval at which the flag is output) becomes shorter than a predetermined time width. If a concentration of stampers is detected, the first
The updating of the contents of the second timer means (sub-timer) by the timer means (master timer) is stopped.
If the time card is inserted during the suspension period, the time is recorded at the same time as when the second timer means stopped updating, although it is different from the actual time. As a result, the time stampers who concentrate on the same time can all record the same time even if the times at which they actually insert their cards are different. On the other hand, if the timer control means detects that the card insertion time interval is equal to or greater than the predetermined time width, it determines that the state in which stampers are concentrated has passed, and changes the contents of the second timer means to the second timer means. 1 to record the actual time.

(f) Examples of the invention Examples of the invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of one embodiment of the present invention.

A constant frequency reference clock signal outputted from an oscillator 1 is input to a master timer 2, which is a first timer means, and a sub-timer controller 5, which is a timer control means. The master timer 2 counts the reference clock signal and outputs the current time. The sub-timer 3, which is the second timer means,
It receives the current time data output from the master timer 2, updates the previous contents with this data, and outputs the updated contents to the card input device 4 as a card input and recording means.

The card input device 4 is equipped with a mechanism for inserting a predetermined card (time card), and when the card is inserted, the contents of the sub-timer 3 are stamped on the card, and a predetermined time card is stamped each time the card is inserted. The flag is output to the sub-timer controller 5 as timer control means.

Each time the flag is input from the card input device 4, the sub-timer controller 5 measures the input time interval with the flag input immediately before, compares this with a predetermined time width, and determines the input time. If the interval is shorter than the predetermined period width, the input gate of the sub-timer 3 is closed to stop updating its contents. If a card is inserted into the card input device 4 during this pause period, the contents of the sub-timer 3 immediately before the pause will continue to be stamped on the card, regardless of the contents of the master timer 2.

On the other hand, if the input time interval of the flag exceeds the predetermined time width, the sub-timer controller 5 opens the input gate of the sub-timer 3, and the contents of the sub-timer 3 are updated according to the contents of the master timer 2 at that time. be done. In other words, the actual time data (time at the time of card insertion) is displayed on the card input device 4.
is entered and stamped on the card based on this.

Next, the main operations of the time recorder of this embodiment will be specifically explained based on the flowcharts of FIGS. 2 and 3. Here, the master timer 2 and sub-timer 3 are respectively referred to as timer T ₁ and timer T ₂ , and the timer included in the sub-timer controller 5 for measuring the card insertion time interval is referred to as timer T ₃ .

The main processing in this embodiment is performed as shown in FIG. That is, first, it is determined whether or not a card has been inserted into the card input device 4 (step _a1 ), and if the card has been inserted, the flag is turned on, that is, the flag is output to the sub-timer controller 5 as described above ( Step _A2 ). Subsequently, the contents of timer T ₂ (sub-timer 3) are read out (step a ₃ ) and recorded by being stamped on the card (step a ₄ ). After that, it moves on to the next process, but
Since this is irrelevant to the gist of the present invention, its explanation will be omitted here.

While the above-mentioned main processing is performed, each time the oscillator 1 outputs a clock signal at a fixed period,
Timer interrupt processing as shown in FIG. 3 is performed.

In timer interrupt processing, first add "1" to timer T ₁ (step b ₁ ), then add "1" to timer T _3.
Similarly, "1" is added to (step b ₂ ). Next, it is determined whether the flag is turned on (see step _a2 in FIG. 2), that is, whether a card is inserted into the card input device 4 (step _b3 ),
If the flag is on, the timer _T3 is reset to "0" (step _b4 ) and the flag is turned off (step _b5 ). As a result of this process, when a card is inserted into the card input device 4, the timer _T3 starts anew measuring the elapsed time from the time of insertion (see step _b2 ).

On the other hand, if the flag is off in step _b3 , that is, after the flag is turned off in step _b5 , the contents of timer _T3 (the elapsed time since the card was inserted) will be changed over a predetermined time period (here, for example, 2 (step b ₆ ),
If two seconds or more have elapsed, the contents of timer _T2 are updated with the contents of timer _T1 (step _b7 ).
On the other hand, if the content of timer _T3 is less than 2 seconds,
The contents of timer _T2 are not updated, and the contents are maintained as they were at the time the flag was turned on.

In this way, the contents of timer _T2 will not be updated until 2 seconds have elapsed since the card was inserted, and the time at the time the card was inserted will remain unchanged. , timer T ₂
The contents of timer _T1 are updated by the contents of timer T1 (actual time). Therefore, if the next stamper inserts a card within 2 seconds after the previous stamper inserted the card, it is assumed that the stampers are concentrated, and the previous stamper inserts the card. On the other hand, if the next stamper inserts a card 2 seconds after the previous stamper inserted the card, it is assumed that the stampers are not concentrating. Like a normal time recorder, the actual time at the time the card is inserted is recorded. In the above process, it was determined whether or not the stamper was concentrating by comparing the elapsed time after the card was inserted with a predetermined time width (2 seconds). can be appropriately set to a value other than 2 seconds.

In the above embodiment, the card input device 4 has both the card input function and the time recording function, and the time is recorded by stamping on the inserted card itself. There is no need to record the time. For example, the card input device 4 is provided with only a card input function, and a recording device 6 capable of recording time on some recording medium is separately provided as shown in FIG. The card input device 4 and the card input device 4 may constitute a card input and recording means in the present invention. As the recording device 6, it is possible to use, for example, a magnetic recording device that records time on a magnetic medium, a printer that records time on paper, or the like. Such a recording device 6 does not need to be placed near the card input device 4, and may be placed, for example, in a data processing center located at a remote location via a line.

In addition, by attaching an identification cover to the card once inserted, and by providing a device for reading the identification display in the card input device 4, it is possible to repeatedly register the time of a card that has already registered the time within the predetermined time range. If an attempt is made to register, for example, the recording device 6 may determine this and cancel the update suspension of the sub-timer 3.

(g) Effects of the Invention According to the present invention, fair time registration is possible even when a large number of card inserters (time card stampers in the case of time cards) are concentrated at the same time. For example, when the time is stamped on a time card, the troublesome work of manually correcting the registered time as in the past becomes unnecessary.
