2. Description of the Related Art A time recorder is provided with a display device using a liquid crystal, and the current time, various messages, or
Although the embossed data and the like are displayed, in order to make the display content of the liquid crystal clearer, the display unit using this liquid crystal has a display portion as shown in, for example, Japanese Utility Model Publication No. 6-25803. In order to illuminate, a light of a backlight configured by using a photoelectric tube such as an LED or a cold cathode tube is used.

In addition, the backlight of the above-mentioned display includes a constant-lighting type of a type in which the time recorder is constantly lit to keep illuminating the display when the time recorder is in an ON state, and a constant time input (stamp) to the time recorder. There is a type in which the backlight is turned off when there is no light, as needed.

[0004]

However, in the case of the former always-on type in which the backlight is continuously illuminated, there is a problem of shortening the life of the backlight, and the latter is turned off when there is no input. In the case of the off-time off type, it is possible to extend the life of the backlight, but in many cases the backlight is turned off at the time of engraving, which causes a problem that the display content of the display cannot be read sufficiently. there were.

Therefore, the technical problem of the present invention is to associate the timing of turning on / off the backlight of the display with the time zone in which the stamping is performed and the time zone in which the stamping is not performed. The backlight is always kept in the ON state to secure the illumination of the display, and at the same time, the life of the backlight is extended.

[0006]

[Means for Solving the Problems] Means taken in the present invention for solving the above technical problems are as follows.

In a time recorder having a function of storing daily working data and a display device for displaying the current time, messages, etc.,

(1) While a backlight for illuminating the display contents is provided on the above-mentioned display, the time zone during which the backlight is turned on and off is automatically determined based on the past work data stored in the memory of the time recorder. Provide a means for determining the backlight turn-on / turn-off time.

(2) As means for deciding the time zone for turning on and off the backlight, the employment data stored in the memory of the time recorder in the past is used, or the employment data of the holiday working days are selected and determined. Provide working day type employment data selection means.

(3) A day-of-the-week type work data selection means for selecting and determining work data for the same day one week before stored in the memory of the time recorder as means for determining the time zone for turning on and off the backlight. Be prepared.

(4) As a means for determining the time period for turning on and off the backlight, when the work data one week ago does not match conditionally, or when one week ago is closed and no work data exists Select the employment data of the same day two weeks ago, and if the employment data of the previous two weeks is not available in the same way, select three weeks before or four weeks before the employment data, but select four weeks before If the employment data of is not available, a calendar-type employment data selection means that selects and determines the employment data of the previous day shall be provided.

(5) As a means for determining the time zone in which the backlight is turned on and off, from the past work data stored in the memory of the time recorder, the first embossing time of each day of the time zone is determined. While selecting and calculating the average time, this average time is determined as the lighting time of the backlight, while the last time stamped every day in the time zone from the past work data also stored in the memory of the time recorder. Select an average time to calculate the average time, and determine the average time as the time to turn off the backlight.

(6) A touch sensor that can turn on the backlight of the display with one touch even during the off time and a forced lighting means that can turn on when working data is stamped.

Each means described in the above (1) to (6) operates as follows.

According to the means described in (1) above, the time zone during which the backlight of the display is turned on and off is determined based on the past work data stored in the time recorder. If there is the first attendance data in the morning at 8:00 am, the backlight is turned on for a certain period of time starting from that attendance time, or for a certain period before and after that,
In addition, for example, when there is the last night's work-out data at PM 10:00, the backlight is turned off within a certain period of time based on the work-out time, and further, the time is stamped between the work time zone and the work time zone. If no data exists,
Since the backlight is turned off, unnecessary lighting of the backlight is reduced as much as possible to extend the life, while the backlight is always turned on at the time of stamping,
It enables to visually check and stamp the display correctly.

According to the means described in the above (2), as the past work data for turning on and off the backlight, the working day having the same working conditions as the working day is selected, or the working day is a holiday work. In the case of a day, the same holiday working days are selected, and the working data for each working day is used as the working data for the day of stamping, and the backlight is turned on and off based on this working data. Since turning on and off the light can be approximated to the working situation on the day of stamping, it is possible to reduce unnecessary lighting of the backlight to prolong life, and at the time of stamping, always turn on the backlight to display the indicator. Makes it possible to illuminate.

According to the means described in the above (3), since the working data of the same day just one week before the date of stamping is used as the past working data for turning on and off the backlight, Since lighting and extinction can be controlled by approximating the working situation on the day of stamping, it is possible to reduce unnecessary lighting of the backlight to prolong its life and to always illuminate the display during stamping. To

According to the means described in (4) above, if the working conditions differ just one week before the embossing day due to a holiday or the like, the working data on the same day two weeks before is used, and further,
If it is a holiday even 2 weeks ago, use the one 3 weeks ago,
If the work data from 3 weeks ago cannot be used, the work data from 4 weeks ago is used, but if the work data from 4 weeks ago is not used, the backlight is turned on and off by using the work data from the previous day. Under any condition, it is possible to select the work data that most closely approximates the date of stamping, and control the turning on / off of the backlight as closely as possible to the actual working conditions.

According to the means described in (5) above, the average time of the earliest work time and the latest work time is calculated from the past work data for the time zone in which the backlight is turned on and off, and these are calculated. Since the lighting of the backlight is controlled according to the average time, the life of the backlight can be efficiently turned on and off to prolong its life, and it is possible to illuminate the display without fail during engraving. Is sequentially updated and the average value of the data is used, so that it is possible to control the turning on / off according to the actual operating time period.

According to the means described in (6) above, in addition to the control of turning on / off the backlight based on the past working data, when the touch sensor is touched even when the backlight is off, and when the stamp is stamped. Since the backlight always turns on when writing, it is possible to print with the backlight illuminating the display even in irregular work where the backlight is normally off, such as early morning or late night work. To do.

As described above, the above-mentioned technical problems can be solved by the above-mentioned means, and the problems of the conventional technology can be solved.

After selecting 7 days in case of this day from this calendar CL,
The working data of the day of the week is called to determine the time zone for turning on / off the backlight 2A according to the basic procedure described in FIG.

However, if the day of engraving (today) is, for example, 30 days, the above-mentioned calendar CL indicates that the 23rd day of the previous week is a national holiday and the working conditions do not match, so the same day two weeks before, that is, the 16th day. Select employment data and determine the time zone of turning on / off the backlight 2A by the method shown in FIG.
Also, if the day of stamping is 18 days off on the calendar CL and is a holiday (some people are working on holidays), the 11th day of the previous week is a normal working day and the conditions do not match. The employment data of (day) is selected, and the time zone of turning on / off the backlight 2A is determined by the method shown in FIG.

As shown in the calendar CL, one day,
If 8th, 15th, and 22nd are closed days and 29th is a working day, the previous 4 weeks are all closed days on the day of 29th and the conditions do not match. The time period for turning on / off the backlight 2A is determined according to the work data of. However, if the date of stamping is 22 days, 1 of the previous week
Since 5 days are holidays under the same conditions, it is configured to use the work data of these 15 days.
When the employment data on the 28th day of the previous day is used like the day, even if the conditions of the two days are different, the employment data of the previous day is used as it is as an extremely rare case.

FIG. 5 is a flow chart for explaining the procedure of the general embossing process including the embodiment of the present invention described in claim 6 and the process of lighting the backlight 2A. In the first step S1, the display is performed. It is determined whether or not the container 2, that is, the backlight 2A is lit, and if it is lit, the process proceeds to step S2 as it is for embossing (printing) processing, and then the process proceeds to step S3 to record the engraving data. Although the process is completed by registering in the memory 6, the backlight 2 is selected in step S1.
If it is determined that A is not lit, the process proceeds to step S4.

In step S4, it is determined whether or not the touch sensor 2B provided on the display device 2 is touched. If the touch sensor 2B is touched, the process proceeds to step S5 to forcibly turn on the backlight 2A, and then the above-described step S2. If the touch is not touched, the process proceeds to steps S6 and S7 to compulsorily turn on the backlight 2A by the stamping, and then proceeds to the registration process of step S3 described above to end the process.

FIG. 6 shows the processing procedure of the present invention as defined in claims 3 and 4, that is, the selection of past work data and the processing of turning on / off the backlight 2A, which are executed every day at 0:30 AM, for example. It is the flowchart explaining the procedure, and in the first step S10, the day of embossing (today) and the same day one week before are viewed as a work calendar in the light of the calendar CL as shown in FIG. 4, for example. It is determined whether the date meets the conditions.

When it is determined in step S10 that the working conditions are met, the process proceeds to the next step S11, in which the working data of one week before is adopted, and the indicator 2 on the day of stamping, that is, the backlight 2A is adopted according to the working data. The time zone of turning on / off of is determined.

Next, in step S12, the employed work data is searched to find the same time zone (current time zone).
It is determined whether or not there is embossing data. If yes, the process proceeds to the next step S13 to turn on the backlight 2A. After lighting, the process proceeds to the next step S14 to see if the lighting time of the backlight 2A has elapsed. If it is determined that it has not elapsed, the process returns to step S13 to continue to turn on the backlight 2A if it has not elapsed, and if it has elapsed, the process proceeds to the next step S15 to stamp in the next time zone of the employed work data. It is determined whether or not there is data. If there is data, the process returns to step S13 to continue lighting the backlight 2A, but if there is no data, the process proceeds to step S16 to turn off the backlight 2A and finish the process.

On the other hand, if it is determined in the first step S10 that the working conditions are not met, that is, the embossed data of one week ago cannot be used, the process proceeds to the next step S17 and the step 2
By looking at the calendar of the same day of the week before, it is determined whether or not the working conditions are met, and if they are met, the next step S1.
In step 8, the employment data of two weeks ago is adopted, and thereafter, the lighting / extinguishing process of step S12 and thereafter is executed according to the employment data of two weeks ago, but if it is determined that they do not match, the process proceeds to step S19. .

In step S19, the calendar of the same day three weeks before is checked to determine whether the working conditions match, and if they match, the process proceeds to step S20 to adopt the working data of three weeks ago, After that, the lighting / lighting-off processing after step S12 described above is executed according to the employment data of three weeks before, but if they do not match, the next step S21.
Proceed to.

In step S21, it is determined whether or not the working conditions are matched by looking at the calendar of the same day four weeks ago, and if they are matched, the process proceeds to step S22 and the working data of four weeks ago is adopted. Thereafter, the lighting / extinguishing process after step S12 described above is executed according to the work data of four weeks ago, but if they do not match, the process proceeds to step S23 to adopt the work data of the previous day, and thereafter, according to the work data of the previous day. The lighting / extinguishing process after step S12 is executed.

FIG. 7 is a flow chart for routinely collecting average value calculation data for carrying out the present invention as set forth in claim 5. The flow chart shown in the drawing is for collecting work time data. However, since the same flowchart can be used to collect the time-of-work data, the description thereof is omitted here.

That is, the first step S30 shown in FIG.
When the work data is stamped on the time card TC, the process proceeds to the next step S31, it is determined whether or not the current stamp is the first attendance stamp in the time zone, and if it is the first stamp, Then, the process proceeds to the next step S32 to register the embossing data in the data area for calculating the average value of the lighting time provided in the memory 6, and if there is old data, update it and finish the process.

On the other hand, if it is determined in step S31 that the attendance stamp is not the first attendance stamp, it is determined in step S33 whether or not the attendance stamp is the latest attendance stamp in the time zone. If the time is late, the process proceeds to step S34 and the time is registered and updated in the data area for calculating the average value of the turn-off time provided in the memory 6, and the process ends, but if it is not the latest time Ends the process as it is.

FIG. 8 uses the first and last time stamps collected daily according to the flow chart shown in FIG. 7 to determine the time zone for turning on / off the backlight 2A, and , A flowchart for explaining a processing procedure for controlling lighting / lighting out. In the first step S40, in the processing executed every day at, for example, AM 0:30, the past employment data is checked to check the morning. It is judged whether or not the stamped data of the first attendance exists in the attendance time zone, in the afternoon departure time zone, or in the limited time zone (that hour zone) if it is one hour. If it exists, the process proceeds to the next step S41 to search the data area for calculating the lighting time average value of the memory 6 described above, and only the first attendance stamp data of the time zone is taken out and set.

Then, in step S42, the average value of the first attendance time stamp data (the data of the first time stamp) set in these steps is calculated, and in the next step S43, the time zone based on this average value is backed up. The light 2A is turned on and the process proceeds to the next step S44.

In step S44, it is determined whether or not the final embossing data exists in the time zone described above. If the final data does not exist, the process proceeds to step S48, and after a lapse of a predetermined time, the backlight in step S49. 2A is turned off and the process is terminated, but when the presence of the final embossing data is confirmed, the process proceeds to step S45, the data area for calculating the extinction time average value of the memory 6 described above is searched, and the end of the time zone Take out only the stamped data and set it.

Next, in step S46, the average value of the final embossing data set in these is calculated, and in the next step S47, the backlight 2A is turned off at the time based on this average value, and the process is terminated.

The backlight 2A may be turned on or off at the time of the average value, or may be set to be turned on for several minutes before or after the time of the average value.

FIG. 9 is a block diagram for explaining the overall structure of the present invention.

[0050]

As described above, according to the backlight control device for a display for a time recorder according to the present invention, a learning function for controlling lighting and extinguishing of the display backlight by using past work data is exhibited. Therefore, the timing of turning on and off the backlight can be divided into the time zone required for embossing and the time zone unnecessary, and the backlight can be turned on only when necessary, so be sure to display the indicator when embossing. Not only can it be illuminated for visual confirmation, but it can also be turned off during unnecessary hours to extend the life of the backlight, which can enhance the function of the display and the commercial value of the time recorder. .
