Abstract

PURPOSE:To make possible the display of time data which corresponds to special workload time without changing date by storing date data of a previous day in a storage device and using the date data in the storage device, f the date data corresponds to data from zero hour to time before time for date change. CONSTITUTION:If power is turned ON, a data administration device 101 reads date data from a timer 30, then resets a data change flag in a storage device 104 and writes the date data which is read in the storage device 104. Next, if a data change detection device 102 detects printing data from a host computer 3, the former reads current date and time data from the timer 30. Then the date change detection device checks whether the current time data which is read corresponds to time before 6 AM, a preset date change time and after 24 hours and further checks whether date data stored in the storage device 104 coincides with current date data which is read. If these data coincide with each other, a display data sending device 103 is started, and prepares printing data from the current date and time data which is read. After this, said device sends the current date and time data to a specified Chinese character printer 2 with the printing data from the host computer 3 to perform printing.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a control device for controlling a display device such as a kanji printer device used in a newspaper company or the like.

(Prior Art) A conventional kanji printer control device reads current date and time data from a clock device of a computer system and uses this data as is as print data.

However, some special businesses such as newspaper companies operate according to a clock system of 6:00 a.m. to 3:30 p.m. The above-mentioned kanji printer cannot be applied as is to such special tasks.

Conventionally, a method has been known in which software is used to obtain an accurate date and time at any time based on a calendar program that includes the month and day from the current date and time.

However, since this method involves a calendar program,
A problem has arisen in which the amount of software required to find the previous day when midnight has passed in the current time becomes enormous. Alternatively, there is a method of installing hardware that independently measures time according to business hours, but this requires special equipment and
A problem has arisen in that the structure becomes larger.

(Problem to be Solved by the Invention) As described above, in some conventional display device control devices, the date of the monologue business hours is determined based on a calendar program that includes the month and day from the current date and time. The problem was that the software became huge. Also,
Some companies have tried to install hardware that measures time according to their own business hours, but this requires special equipment and increases the size of the structure.

The present invention has been made to solve the problems of the conventional control device for display devices, and its purpose is to eliminate the need for special devices and, therefore, to avoid increasing the size of the configuration.
Another object of the present invention is to provide a control device for a display device that has a simple configuration and can easily measure time that matches a unique business time and send it out as display data.

[Structure of the Invention] (Means for Solving the Problems) The present invention includes: a timer for measuring the current date and time; a storage means for storing date data; and a timer for measuring the current date and time; date management means for storing date data in the storage means; and date change detection means for detecting whether the current time data read from the timer is a time at which no date change is required before a date change time obtained in advance from 0:00. When this date change detection means detects that the date is not required to be changed, 2 is added to the date data in the storage means and the read current time data.
Display data sending means for sending out time data with 4 o'clock added thereto as display data, while sending out the current date data and current time data read from the timer as display data when it is detected that the date is not required to be changed; A control device for the display device was constructed by providing the following.

(Function) According to the above configuration, the date management means can function to store the date data whose date has been changed in the storage means at the time when the predetermined date change time is exceeded, and the date data in the storage means can be stored in the storage means. Since the display data is created and sent using data, there is no need to change the date even after 24 hours.
Date and time data measured in accordance with unique business hours can now be displayed as display data.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. FIG. 2 is a block diagram of a computer system including a kanji printer control device 1 according to an embodiment of the present invention. Kanji printers 21 to 2o that print kanji characters are connected to the kanji printer control device 1, and the kanji printer control device 1 receives current date and time data 1q from the timer 30 of the host computer 3 that is also connected, and prints (displays) the date and time. ) Create data and send it to the kanji printer 2. The kanji printer control device 1 is provided with a control section 11 for controlling the device and a memory 12 in which programs are stored and has a working area. It functions as date management means 101, date change detection means 102, and display data sending means 103 in FIG. Further, the memory 12 functions as a storage means 104. Here, the operation will be explained when the business hours are from 6:00 a.m. to 1930:00 p.m. First, by initial setting, 6:00 AM is stored in the storage means 104, which is the memory 12, as date change time data. Next, when the power is turned on, the control section 11 operates as the date management means 101 as shown in FIG. In this embodiment, the power is turned on after 6:00 a.m. at the original time and before 24:00 (this is specified in the specifications, etc.).

When the power is turned on, the date management means 101 starts the timer 3.
The date data is read from 0 and the daily change flag (not shown) in the storage means 104 is reset (301).Next, the date management means 101 reads the date data (
Write the date (year, month, and day) to the storage unit 104 (302) a.Next, the date change detection unit 102 operates and detects whether or not print data has been sent from the host computer 3 (302).
303). Here, when the presence of print data is detected, the current date and time data (year, month, day, hour, minute, second) is read from the timer 30 (
304). Then, the date change detection means 102 detects whether the read current time data (hours, minutes, seconds) is before the preset date change time of 6 AM and after 24:00 (0:00) (305). Then, date change detection means 102
If the result in step 305 is YES, it is detected whether the daily change flag is zero (reset state) (307).

Here, if the daily change flag is in the reset state, the date change detection means 102 detects whether the date flag stored in the storage means 104 and the read current date data match (308). If they match at this time, the display data sending means 103 is activated, creates print data based on the read current date and time data, and sends it to the required Kanji printer 2 together with the print data sent from the host computer 3 for printing (309). . In this way, Q:OO~5:5
When the print data is sent at 9:00, the date data stored in the storage means 104 and the current date data read match.
In this case, printing is performed using the current date and time data as an emergency measure. On the other hand, if there is a mismatch in step 308, the display data sending means 103
Print data is created using the date data stored in 4 and the time data obtained by adding 24 hours to the read current time data, and sent to the required kanji printer 2 together with the print data sent from the host computer 3 for printing. (310). Then, the date management means 101 is activated, sets the daily change flag (311), and returns to step 303. After the daily change flag is set in this way, the current time data read from the timer 30 is
0 to 5:59, the daily change flag is set, so the process proceeds from step 307 to step 312, and the display data sending means 103 stores the data in the storage means 10.
Print data is created using the date data stored in 4 and the time data obtained by adding 24 hours to the read current time data, and is sent to the required kanji printer 2 together with the print data sent from the host computer 3. Printing is performed (312) and the process returns to step 303. Further, if the date change detection means 102 detects that the current time data read in step 304 is not from Q:00 to 5:59, the process proceeds from step 305 to step 306, and the current time data read by the display data sending means 103 is Print data is created based on the date and time data, and sent together with the print data sent from the host computer 3 to the required Kanji printer 2 for printing (306). Then, after this, date management means 1
01 is activated, and a match between the date data in the storage means 104 and the current date data read out from the timer 30 is detected (313), and if they do not match, date adjustment is performed (314). Thus, according to this embodiment, it is possible to manage date changes and time data creation by simple comparison without performing steps such as setting the date back or forward using calendar data, and the power can be turned on according to specifications. As long as you do this, you can obtain records with printed times that accurately correspond to special business hours.

Incidentally, in this embodiment, the flowchart shown in FIG. 3 is started when the power is turned on, but for example, a start command may be inputted using an input means such as an appropriate switch. The invention is applicable not only to kanji printers but also to a wide range of control devices for display devices.

[Effects of the Invention] As explained above, according to the present invention, the date data of the previous day is stored in the storage means, and from midnight until before the date change time obtained in advance, the data of the previous day is stored in the storage means. Since the date data can be used as display data, it has the advantage of being able to easily measure time that matches the unique business hours and send it out as display data with a simple configuration.
