BACKGROUND OF THE INVENTION
The present invention relates to a printing apparatus that prints various types of print data relating to a fire detection situation in a prevention receiving board or the like, and more particularly to a printing apparatus characterized by the print order of print data.
[0002]
[Prior art]
Today, printing apparatuses for printing various types of print data are widely used in various fields. For example, a printing apparatus is also provided in a disaster prevention receiving board that monitors a signal from a fire detector for detecting a fire. Unlike a display device, such a printing device has an advantage that print data can be permanently confirmed at an arbitrary place.
[0003]
Such a printing apparatus is often configured to be usable by switching between two printing modes, a first mode (hereinafter referred to as a sequential printing mode) and a second mode (hereinafter referred to as a history printing mode). .
Among these, the sequential printing mode is a mode in which, when various events such as the occurrence of a fire or the occurrence of an abnormality of a fire detector occur, the print data relating to this event is printed immediately.
The history print mode is a mode in which the print data is recorded in a recording unit, and when printing is instructed, a plurality of print data recorded in the recording unit are continuously printed. According to this history printing mode, the contents of a plurality of events can be easily confirmed at an arbitrary timing.
[0004]
Here, in the conventional history print mode, a plurality of print data is printed in the oldest order. An example of printing in such a conventional history printing mode is shown in FIG. In FIG. 5, three types of print data of start data KD, event data ID <b> 1 to IDn, and end data SD are printed on the print sheet 100 a fed out from the print unit 100.
Among these, the start data KD is data including the start of history printing and its time, etc., the event data ID1 to IDn are data including the contents and times of various events, and the end data SD is This data includes the fact that history printing has been completed and the time.
As shown in FIG. 5, the event data ID1 to IDn are printed in the print direction along the feed-out direction (a direction that can be normally read when facing the print unit 3; hereinafter referred to as a first print direction) D1. It was printed in order from the old event data ID1 to the new event data IDn.
[0005]
[Problems to be solved by the invention]
However, in the conventional printing order in such a history printing mode, since a plurality of event data ID1 to IDn are printed in the oldest order, it takes time to print the latest event data IDn that is normally required. Was. In particular, in the history print mode, the larger the number of event data ID1 to IDn, the better the history can be ascertained. However, as the number of event data ID1 to IDn increases, the latest event data IDn is printed. In some cases, the number of event data ID1 to IDn has to be reduced because of the problem that it takes a long time to complete.
[0006]
The present invention has been made in view of the above problems, and an object thereof is to provide a printing apparatus capable of optimizing the printing order in the history printing mode.
[0007]
[Means for Solving the Problems]
In order to achieve such an object, a printing apparatus according to claim 1 is a printing apparatus for printing print data, and among the print data, predetermined print data is transmitted in a first print direction. Event data that is print data related to each of a plurality of events that occurred at different times is printed on a print sheet, and the event data that is the reverse of the first print direction in the order of the event occurrence time . It is characterized by comprising printing control means for sequentially printing in the second printing direction .
[0008]
According to this apparatus, since new print data is printed in order, necessary print data can be viewed in a short time. Further, since the printed from the new print data sequentially by discontinued Printout After the desired print data has been printed, it is possible to save printing time and the printing sheet.

When the first print mode is set , each of the plurality of events occurring at different times is related. When event data, which is print data, is sequentially printed in the first print direction in the order of the event occurrence time , and the second print mode is set, the event data is set to the event occurrence time. It is characterized by comprising print control means for sequentially printing in a second print direction opposite to the first print direction in the new order.
[0010]
According to this apparatus, 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 both are different, so that both can be easily identified. it can.
[0011]
According to a third aspect of the present invention, in the printing apparatus according to the second aspect , the print control unit is configured to set predetermined print data out of the print data and the first print mode. and if you are, in the case where the second print mode is set, characterized in that make printed in the same printing direction.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments 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 receiving board that monitors a signal from a fire detector for detecting a fire. In addition, this invention is not limited by this embodiment.
[0016]
(Outline of printing)
First, an outline of printing by this apparatus will be described. In this apparatus, as in the conventional case, two types of printing modes, a sequential printing mode and a history printing mode, can be switched and used. Specifically, the normal printing mode is set to the sequential printing mode, and the history printing mode is switched when a predetermined operation is performed.
[0017]
In this history print mode, three types of print data, that is, start data KD, event data ID, and end data SD are printed as in the conventional case.
Of these, the start data KD and the end data SD are printed in the same print direction and print order as in the prior art. On the other hand, the event data ID has a print direction opposite to the conventional print direction (a direction in which the reading direction is reversed in a state of facing the print unit 3 to be described later. Hereinafter, the second print direction) Printing is performed in the reverse printing order.
[0018]
(Equipment configuration)
Next, a specific configuration of the device will be described.
FIG. 1 is a block diagram showing a configuration example of a part related to the present invention in the disaster prevention receiving board. As shown in FIG. 1, the disaster prevention reception board 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. .
[0019]
Among these, the operation part 2 is an input means for performing various operations with respect to the disaster prevention receiving board 1, and is specifically provided with a history print switch 2a and a print stop switch 2b. The history print switch 2a is history print instruction means for instructing printing in the history print mode. The print stop switch 2b is a print stop instruction means for instructing to stop printing.
[0020]
The printing unit 3 is a printing unit that performs sequential printing and history printing under the control of a printing control unit 6a described later. 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 respect to the operation unit 2 and the printing unit 3 and the fire detector 10 set at an arbitrary place.
[0021]
The storage unit 5 is a storage unit that stores various programs and data necessary for the control of the disaster prevention receiver 1 in a volatile or non-volatile manner. In particular, the storage unit 5 stores an event data ID.
The control unit 6 is a control unit that controls each unit of the disaster prevention reception board 1. The control unit 6 is provided with a print control unit 6a in terms of functional concept. The print control unit 6a is a print control unit that sequentially prints event data IDs related to a plurality of events that occurred at different times in the order of the event occurrence time. Details of the contents of control by the print controller 6a will be described later.
[0022]
(Processing content-sequential printing process)
Next, the contents of the process will be described. Note that 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 first. As described above, the sequential printing mode is normally set. In this sequential printing mode, the control unit 6 monitors a fire occurrence signal from the fire detector and performs control for periodically conducting a function test of the fire detector.
[0023]
When various events such as occurrence of fire or abnormality occur, the control unit 6 performs predetermined control for taking a necessary response to this event, and stores an event data ID related to this event in the storage unit 5 and further instructs the print controller 6a to start printing sequentially. At this time, the event data ID in the storage unit 5 is stored along the time series when the event occurs.
[0024]
The print control unit 6a obtains the current date and time by an arbitrary method, generates start data KD including the date and time, and prints the start data KD and the event data ID called from the storage unit 5. Output to the 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. An example of this printing is shown in FIG. In FIG. 3, a printing sheet 3a is fed out from the printing unit 3, and start data KD and event data ID are printed in the first printing direction D1 on the printing sheet 3a. Then, the administrator can grasp the fact that the event has occurred and its contents by looking at the print sheet 3a at an arbitrary timing, and cut out the print sheet 3a and save it by an arbitrary method. I can leave.
[0025]
(Processing content-history printing process)
Next, the contents 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 printing mode, the control unit 6 instructs the printing control unit 6a to start history printing.
[0026]
The print controller 6a starts history printing by history printing processing. A flowchart of this process is shown in FIG. An example of printing by this processing is shown in FIG.
As shown in FIG. 2, the print control unit 6a generates start data KD 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 printing direction D1.
[0027]
Next, as shown in FIG. 2, the printing control unit 6a outputs a printing direction switching command 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.
Thereafter, the print control unit 6a sequentially calls out all the event data IDs stored in the storage unit 5 in order from the new event data IDn to the old event data ID1, and outputs them to the printing unit 3 (step S-). 3, S-4). And this printing part 3 prints event data IDn-ID1 input into self one by one. As a result, as shown in FIG. 4, the event data IDn to ID1 are printed in the new order in the second print direction D2.
[0028]
In FIG. 2 again, after the output of all the event data IDn to ID1 is completed, the print control unit 6a again outputs a print direction switching command to the print unit 3 (step S-5). As a result, the printing direction in the printing unit 3 is switched to the original first printing direction D1, and the printing control unit 6a obtains the date and time at that time by an arbitrary method and terminates including this date and time. Data SD is generated, the end data SD is output to the printing unit 3, and a print command is output (step S-6). As a result, as shown in FIG. 4, the end data SD is printed in the first printing direction D1.
[0029]
Thus, the history printing process is completed, and the mode is automatically switched to the sequential printing mode again.
If the administrator depresses the print stop switch 2b or a predetermined interrupt event occurs at any timing during the history printing process, the print control unit 6a immediately prints on the printing unit 3. To cancel.
[0030]
Such a history printing process generally has the following advantages.
First, since the new event data IDn is printed in order, the administrator can view the necessary event data IDn in a short time.
Further, since the new event data IDn is printed in order, the printing time and the print sheet 3a can be saved by stopping printing as described above after the necessary event data IDn is printed.
Even when the sequential printing process and the history printing process coexist, the event data IDs are printed in different directions, so that both can be easily identified.
[0031]
Further, as apparent from FIGS. 3 and 4, since the start data KD and the end data SD are printed in the first print direction D1, the administrator can select the print mode with the print sheet 3a being fed out. It is possible to easily grasp the contents and the date and time.
Here, in the history printing process, it is conceivable to print the individual event data IDs in the first printing direction D1 in addition to printing in order from the newest. 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.
[0032]
However, when the event data ID is printed in the second printing direction D2 as shown in FIG. 4, when the print sheet 3a is cut out and attached to the report, it is attached upside down from FIG. Thus, the printing order and the printing direction can be made to be in the same state as the printing sheet 3a of the sequential printing process (the state where the old event data ID1 is on the near side and in the normal reading direction), and the printing sheet 3a. Management, reading, etc. become easier.
[0033]
Although the embodiments of the present invention have been described so far, the present invention can be applied to various different embodiments in addition to the above-described embodiments within the scope of the technical idea described in the claims. May be implemented.
For example, the present 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 receiving board 1 or the like. In this case, the printing apparatus includes, for example, a history printing switch 2a, a printing stop switch 2b, an input / output IF 4, a storage unit 5, a printing control unit 6a, and a printing unit 3.
[0034]
In addition to changing the printing order of the print data as described above, the print form of the print data can be further changed.
For example, event data IDs may be grouped for each of a plurality of attributes according to the contents, and may be printed together for each attribute. For example, the attribute of the event data ID is divided into two, fire occurrence and abnormality of the fire detector. In the history printing process, first, all event data IDs related to the fire occurrence are set in the second print direction. D2 may be printed in the newest order, and then all event data IDs relating to the occurrence of an abnormality of the fire detector may be printed in the second printing direction D2 in the newest order. In this case, the print data for specific contents can be read intensively, and the print data can be grasped more easily.
[0035]
In addition, among the processes described in the embodiment, all or part of the processes described as being automatically performed can be performed manually, or all of the processes described as being performed manually are performed. Alternatively, a part can be automatically performed by a known method.
In addition, information including parameters such as processing procedures, control procedures, specific names, various registration data and search conditions shown in the above documents and drawings can be arbitrarily changed unless otherwise specified. .
[0036]
【The invention's effect】
As described above, according to the present invention, since new print data is printed in order, necessary print data can be viewed in a short time.
Also, since new print data is printed in order, printing time and a print sheet can be saved by stopping printing as described above after necessary print data is printed.
[0037]
In addition, according to the present invention, even when printing in the first printing mode and printing in the second printing mode are mixed, the printing direction of the printing data in both is different, so that both are easily identified. be able to.
[0038]
In addition, according to the present invention, start data, end data, and the like can be printed in the first print direction, and the contents of the print mode and the date and time thereof can be easily grasped while the print sheet is fed out. Can do.
In addition, when the print sheet printed in the second mode is cut out and attached to the report, the print order and the 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 printed sheet.
[0039]
Further, according to the present invention, since the print data is printed for each attribute, the print data for specific contents can be read intensively, and the print data can be grasped more easily.
