Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing apparatus for printing various print data and the like relating to a fire detection situation on a prevention receiver or the like, and more particularly to a printing apparatus having a feature in a printing order of print data.

[0002]

2. Description of the Related Art At present, printing apparatuses for printing various print data are widely used in various fields. For example, a printing device is also provided in a disaster prevention receiver that monitors a signal from a fire detector for detecting a fire. Such printing devices, unlike display devices,
This has the advantage that print data can be permanently checked at any location.

Such a printing apparatus is configured to be able to use by switching between two printing modes, a first mode (hereinafter, a sequential printing mode) and a second mode (hereinafter, a history printing mode). Often. Among these, the sequential printing mode is a mode in which when various events such as a fire occurrence or a fire detector abnormality occur, print data relating to the event is immediately printed. The history print mode is a mode in which the print data is recorded in a recording section, and when printing is instructed, a plurality of print data recorded in the recording section are continuously printed. According to the history print mode, the contents of a plurality of events can be easily confirmed at an arbitrary timing.

[0004] In the conventional history print mode, a plurality of print data are printed in chronological order. FIG. 5 shows an example of printing in such a conventional history printing mode. In FIG. 5, three types of print data of start data KD, event data ID1 to IDn, and end data SD are printed on the print sheet 100a fed from the printing unit 100. Among them, the start data KD is data including the fact that the history printing has started and the time thereof, the event data ID1 to IDn are data including the contents of various events and the time thereof, and the end data SD is This is data that includes the end of history printing and the time. As shown in FIG. 5, the event data ID1 to IDn are printed in a printing direction (a direction that can be read normally in a state directly facing the printing unit 3; hereinafter, a first printing direction) D1 along the feeding direction. The printing is performed in order from the old event data ID1 to the new event data IDn.

[0005]

However, in the conventional printing order in such a history printing mode, a plurality of event data ID1 to IDn are printed in an old order, so that the latest event data ID which is usually required is used.
It took time until n was printed. In particular, in the history print mode, it is preferable that the number of event data ID1 to IDn is large, since the history can be grasped in detail. However, as the number of event data ID1 to IDn increases,
Since it takes a long time to print the latest event data IDn, the event data I
In some cases, the number of D1 to IDn had to be suppressed.

The present invention has been made in view of the above problems, and has as its object to provide a printing apparatus that can optimize a printing order in a history printing mode.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a printing apparatus according to the present invention will be described below in detail with reference to the drawings. In this embodiment, an example will be described in which the present apparatus is provided integrally with a disaster prevention receiver that monitors a signal from a fire detector for detecting a fire. The present invention is not limited by the embodiment.

(Overview of Printing) First, an overview of printing by the present apparatus will be described. In this apparatus, as in the related art, two types of printing modes, a sequential printing mode and a history printing mode, can be switched and used. More specifically, the normal printing mode is set sequentially, and the mode is switched to the history printing mode when a predetermined operation is performed.

In this history print mode, as in the prior art,
Three types of print data of start data KD, event data ID, and end data SD are printed. Of these, the start data KD and the end data SD are printed in the same print direction and print order as in the related art. On the contrary,
The event data ID is a printing direction that is opposite to the conventional printing direction (a direction in which the reading direction is opposite when facing the printing unit 3 described later; hereinafter, a second printing direction) D2, and is opposite to the conventional printing direction. Print in the printing order.

(Equipment Configuration) Next, the specific configuration of the equipment will be described. FIG. 1 is a block diagram showing a configuration example of a part related to the present invention in a disaster prevention receiver. As shown in FIG. 1, the disaster prevention receiver 1 includes an operation unit 2, a printing unit 3, an input / output interface (hereinafter, input / output IF) 4, a storage unit 5, and a control unit 6. .

The operation section 2 is an input means for performing various operations on the disaster prevention receiving board 1, and is particularly provided with a history print switch 2a and a print stop switch 2b. The history printing switch 2a is history printing instruction means for instructing printing in the history printing mode. The print stop switch 2b is a print stop instruction unit for instructing stop of printing.

The printing unit 3 includes a printing control unit 6 described later.
This is a printing unit that performs sequential printing and history printing under the control of a. The printing unit 3 has a function of switching the printing direction between the first printing direction D1 and the second printing direction D2 based on the control of the printing control unit 6a. The specific configuration of the printing unit 3 is arbitrary, and for example, a line thermal printer can be used.
The input / output IF 4 exchanges input / output data with the operation unit 2 and the printing unit 3 and with the fire detector 10 set at an arbitrary location.

The storage unit 5 is a storage unit that stores various programs and data necessary for controlling the disaster prevention receiver 1 in a volatile or nonvolatile manner. In particular, the storage unit 5 stores the event data ID. The control unit 6
Is control means for controlling each part of the disaster prevention receiver 1. The control unit 6 is provided with a print control unit 6a as a function concept. The print control unit 6a roughly stores event data IDs relating to a plurality of events occurring at different times in the order of the event occurrence time in the new order.
Printing control means for sequentially printing. This print controller 6
The details of the control by a will be described later.

(Processing Contents-Sequential Printing Process) Next, the contents of the processing will be described. The printing direction in the printing unit 3 is set to the first printing direction D1 as a default. First, the sequential printing process will be described. As described above, the printing mode is usually set to the sequential printing mode. In the sequential printing mode, the control unit 6 monitors a fire occurrence signal from the fire detector and performs control for periodically performing a function test of the fire detector.

When various events such as a fire or an abnormality occur, the control unit 6 performs predetermined control for taking necessary measures against the event,
The storage unit 5 stores the event data ID relating to this event, and further instructs the print control unit 6a to sequentially start printing. At this time, the event data ID in the storage unit 5 is stored in chronological order at the time of event occurrence.

The print controller 6a obtains the date and time at that time by an arbitrary method, generates start data KD including the date and time, and generates the start data KD and the event data ID called from the storage unit 5. Are output to the printing unit 3 to output a print command. As a result, in the printing unit 3, the start data KD and the event data ID are printed in the first printing direction D1. FIG. 3 shows an example of this printing.
In FIG. 3, a print sheet 3a is fed out of the print unit 3, and start data KD and event data ID are printed on the print sheet 3a in a first print direction D1. Then, the administrator sets the print sheet 3
By viewing a at an arbitrary timing, it is possible to grasp that an event has occurred and its contents, and it is possible to cut out the print sheet 3a and save it by an arbitrary method.

(Processing Content-History Printing Process) Next, the content of the history printing process will be described. As described above, when the administrator depresses the history print switch 2a, the history print mode is set. In this history print mode, the control unit 6 instructs the print control unit 6a to start history print.

The print controller 6a starts history printing by history printing processing. FIG. 2 shows a flowchart of this process. FIG. 4 shows an example of printing by this processing.
As shown in FIG. 2, the print control unit 6a generates start data KD in the same manner as described above, outputs the start data KD to the print unit 3, and outputs a print command (step S-).
1). As a result, as shown in FIG. 4, the start data KD is printed in the first print direction D1.

Next, as shown in FIG. 2, the print control unit 6a
Outputs a printing direction switching command for switching the printing direction in the printing unit 3 to the printing unit 3 (step S
-2). As a result, the printing direction in the printing unit 3 is switched to the second printing direction D2. After that, the print controller 6
“a” is sequentially called from the new event data IDn to the old event data ID1 among all the event data IDs stored in the storage unit 5 and output to the printing unit 3 (steps S-3 and S-4). ). The printing unit 3 stores the event data IDn to I input to itself.
D1 is sequentially printed. As a result, as shown in FIG. 4, the event data IDn to ID1 are printed in the second printing direction D2 in the new order.

In FIG. 2 again, after the output of all the event data IDn to ID1 is completed, the print control unit 6a
The printing direction switching command is output to the printing unit 3 again (step S-5). As a result, the printing direction in the printing unit 3 is switched to the original first printing direction D1.
The print control unit 6a acquires the date and time at that time by an arbitrary method, generates end data SD including the date and time, outputs the end data SD to the printing unit 3, and outputs a print command. (Step S-6). As a result, as shown in FIG. 4, the end data SD is printed in the first print direction D1.

This completes the history printing process and automatically switches to the sequential printing mode again. At any time during the history printing process, when the administrator presses down the print stop switch 2b or when a predetermined interrupt event occurs, the print control unit 6a immediately prints in the printing unit 3. To stop.

The history printing process has the following advantages. First, since the new event data IDn is sequentially printed, the administrator can see the necessary event data IDn in a short time. Also,
Since it is printed in order from new event data IDn,
By stopping the printing as described above after the necessary event data IDn is printed, the printing time and the printing sheet 3a can be saved. Even in the case where the sequential printing process and the history printing process coexist, both can be easily identified because the event data IDs are printed in different directions.

Further, as is apparent from FIGS. 3 and 4, the start data KD and the end data SD are printed in the first print direction D1, so that the administrator can operate the printer in a state where the print sheet 3a is fed out. In addition, the contents of the print mode and the date and time thereof can be easily grasped. Here, in the history printing process, in addition to printing the individual event data IDs in the new order, printing in the first printing direction D1 is also conceivable. In this case, it becomes easier for the administrator to read the contents of the event data ID in a state where the print sheet 3a is fed out.

However, as shown in FIG.
Is printed in the second print direction D2, so that when the print sheet 3a is cut out and attached to a report or the like, the print order and the print direction are sequentially changed by attaching the print sheet 3a upside down from FIG. The same state as that of the print sheet 3a in the printing process can be obtained (the old event data ID1 is on the front side and in the normal reading direction), and the management and reading of the print sheet 3a are facilitated.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, but may be implemented in various different forms within the scope of the technical idea described in the appended claims. It may be implemented in the form of. For example, the printing apparatus can be used for printing arbitrary print data, and can be configured as an independent printing apparatus without being incorporated in the disaster prevention receiver 1 or the like. In this case, the printing apparatus includes, for example, a history print switch 2a, a print stop switch 2b, an input / output IF 4, a storage unit 5, a print control unit 6a, and a print unit 3.

Further, in addition to changing the printing order of the printing data as described above, the printing form of the printing data can be further changed. For example, event data I
D is grouped into a plurality of attributes according to its contents,
It may be printed collectively for each attribute. For example, the attribute of the event data ID is divided into two, that is, a fire occurrence and a fire detector abnormality occurrence.
All event data IDs related to fire occurrence are printed in the second printing direction D2 in the new order, and then all event data IDs related to fire detector abnormality occurrences are printed in the second printing direction D2 in the new order. You may. In this case, the print data of specific contents can be read intensively, and the print data can be grasped more easily.

In addition, of the processes described in the embodiment, all or a part of the processes described as being performed automatically can be manually performed, or
All or a part of the processing described as being performed manually may be automatically performed by a known method. In addition, the processing procedures, control procedures, and
Information including parameters such as specific names, various types of registration data, and search conditions can be arbitrarily changed unless otherwise specified.

As described above, according to the present invention, printing is performed sequentially from new print data, so that required print data can be viewed in a short time. In addition, since printing is performed sequentially from new printing data, printing is stopped as described above after necessary printing data is printed, so that printing time and printing sheets can be saved.

Further, according to the present invention, even when the printing in the first printing mode and the printing in the second printing mode are mixed, the printing directions of the printing data in the two printing modes are different from each other. Can be identified.

Further, according to the present invention, start data, end data and the like can be printed in the first printing direction, and the contents of the print mode and the date and time thereof can be easily determined in a state where the print sheet is fed out. You can figure out. Further, when a print sheet printed in the second mode is cut out and attached to a report or the like, the print order and print direction can be set to the same state as the print sheet printed in the first mode, It becomes easy to manage and read the print sheet.

Further, according to the present invention, since the print data is printed for each attribute, the print data of a specific content can be read intensively, and the print data can be more easily grasped. .
