Description

[Detailed Description of the Invention] Technical Field The present invention relates to a recording device, and particularly to a recording device that prevents duplication of multiple types of symbols sequentially written on recording paper.

Prior Art and its Problems A recording device that sequentially writes symbols corresponding to input keys on recording paper at positions corresponding to the operation times of the input keys along a time axis according to the operation times of multiple types of input keys. is being considered.

However, in such a conventional recording device, there are two types of symbols: one is a symbol that is written in response to an input operation on one of a plurality of input keys based on the operation time, and the other is a symbol that has been input before that using another input key. If there is not a sufficient time interval between them, there is a problem in that adjacent symbols overlap, making it difficult to read them.

Means to Solve the Problems The present invention was developed against the background of the above-mentioned circumstances, and its gist is that it supports multiple types of input keys and the input keys based on the operation time of the input keys. The recording paper is provided along the time axis on the recording paper, and is provided along the time axis on the recording paper. A recording device of a type that sequentially writes the symbols at positions corresponding to the operation time of the input key in the symbol entry area, the recording device including: (a) writing the symbol from the operation time of the input key; (b) a time axis position determining means for determining the time axis position of the
The position of the symbol in the time axis direction determined by the time axis direction position determining means in the first entry area of the plurality of entry areas provided in parallel along the time axis and the symbol already written. and (c) if the overlap determining means determines that the symbols do not overlap, the writing position of the symbol in the direction perpendicular to the time axis. and a time-axis vertical position determination means for determining the position in the first writing area, and determining the position in the other writing area if it is determined that they overlap.

Operation In this way, as shown in the complaint correspondence diagram in FIG. The writing position of the symbol in the time axis direction is determined from the input key operation time, and the position in the time axis direction is compared with the symbol already written in the first writing area by the duplication determining means, thereby determining whether the symbol overlaps with the symbol already written in the first writing area. It is decided whether or not to do so. If it is determined that there is no overlap, the time axis vertical position determining means determines the entry position of the symbol within the first entry area, but if it is determined that there is overlap, the entry position of the symbol is determined within another entry area. do. Then, the symbol is written by the recording control means at the position determined by the writing position determining means as described above.

Effects of the invention Therefore, according to the invention, if a symbol input in response to an input key operation is entered in the first entry area, it is determined that the symbol overlaps with an already entered symbol. Since the writing position is determined within another writing area that does not overlap with the already written symbols, it is possible to prevent multiple symbols from being written twice on the recording paper. .

A plotter control device 42 is provided on the side surface of the X-Y plotter 22, and this plotter control device 42 is constructed as shown in FIG.
The signal supplied from the control device 16 to the input port 48 represents the entry position in the two-dimensional chart recording area 20 and the symbol to be entered,
The CPU 50 utilizes the memory function of the RAM 52.
The input signal is processed according to a program stored in advance in the ROM 54, and driving power is supplied to the X-direction pulse motor 26 so that the symbol indicated by the input signal is written by the pen 38 at the entry position indicated by the input signal. Drive circuit 56, Y direction pulse motor 32
A drive signal is supplied to a drive circuit 58 that supplies drive power to the upper and lower solenoids 36, and a drive circuit 60 that supplies drive power to the upper and lower solenoids 36. Further, in response to an input operation using the input key 44, the CPU 50 causes an event symbol of the type corresponding to the operated input key 44 to be written at a position corresponding to the input time in the two-dimensional chart recording area 20, and , are sequentially entered in predetermined locations in the notes column 21. Therefore, the plotter control device 42 corresponds to the recording control means of this embodiment.

That is, as shown in the flowchart of FIG. 8, first, step S1 is executed to determine whether or not there is a signal input from the control device 16. If there is no signal input, step S1 is repeatedly executed and the device enters a standby state, but if it is determined that there is a signal input, step S2 is executed to determine the entry position represented by the signal and the line for drawing the symbol. The entry trajectory is calculated. In the following step S3,
A drive signal is sequentially output to the drive circuit 56, drive circuit 58, and drive circuit 60 so that the pen 38 writes along the writing trajectory. Then, in the following step 4, the pen 38 is moved to the original position, that is, to the anesthesia recording paper 1.
By returning the information on the anesthesia record sheet 18 to a position that does not interfere with reading the information on the anesthesia record sheet 18,
In particular, this is to make the two-dimensional chart recording area 20 easier to see.

During execution of the main routine, the interrupt routine shown in FIG. 9 interrupts periodically, for example every 10 ms. That is, first,
In step ST1, it is determined whether any of the plurality of input keys 44 for entering an event symbol has been operated. If it is determined that the input key 44 has not been operated, the interrupt routine is terminated, but if it is determined that the input key 44 has been operated, the input key 44 is determined based on the time signal included in the signal supplied from the control device 16 in the following step ST2. At the same time as the operation time is determined, the entry position of the symbol corresponding to the operated input key 44 in the time axis direction along the horizontal axis 78 of the two-dimensional chart recording area 20 is determined based on the determined operation time. be done. Therefore, step ST2 corresponds to the time axis direction position determination means of this embodiment.

Next, by executing step ST3,
When an event symbol is written at a position in the event symbol entry area 23a in the first column that corresponds to the entry position in the time axis direction determined in step ST2, it is determined that the event symbol has already been written in the entry area 23a in the first column. It is determined whether the event symbol overlaps with other event symbols. Since there is no overlap at first, step ST4 is executed, and the CPU 50 outputs a drive signal to drive the pen 38, so that the event symbol is placed at the position corresponding to the input time in the event symbol entry area 23a of the first column, for example. At the same time that "1" shown in FIG. 5 is written, the same event symbol "1" is written in a predetermined fixed position in the notes column 21.

Subsequently, when one of the plurality of input keys 44 is inputted again, steps ST1 and
By executing ST2, the entry position in the time axis direction of the event symbol "2" corresponding to the operated input key 44 is determined, and the following step ST3 is executed, but the event that has already been entered is If the current event symbol "2" is input before sufficient time has elapsed since the input time of the symbol "1", the event symbol "2" is entered in the event symbol entry area 23a in the first row. It is determined that it overlaps with event symbol "1". Then, by executing step ST5, the current event symbol "2" is written at the entry position in the time axis direction determined in step ST2 in the event symbol entry area 23b of the second column. In case,
It is determined whether the event symbol overlaps with other event symbols. If it is determined that there is no overlap, step ST6 is executed, and as shown in FIG. 5, an event symbol "2" is written in the position corresponding to the operation time in the event symbol writing area 23b in the second column. and,
Immediately after the event symbol "2" is input, if the input key 44 is further operated and the event symbol "3" is input, the input time of this event symbol "3" is the previously entered event symbol "1". And since not enough time has passed since the input time of "2",
In step ST3, it is determined that it overlaps with the event symbol "1" in the entry area 23a of the first column, and in step ST5, it is determined that it overlaps with the immediately preceding event symbol "2" in the entry area 23b of the second column. By executing step ST7, the event symbol is immediately written in the event symbol entry area 23c in the third column.

In addition, for event symbols "4" and "5" input after event symbol "3", the input time of the event symbol "4" and "5" must be changed from the input time of other event symbols that have already been entered to the extent that they do not overlap with those other event symbols. Since they are sufficiently separated, it is determined that they do not overlap with other event symbols written in step ST3 or with each other, and are respectively written in the event symbol writing area 23a of the first column.

From the above, in this embodiment, step ST3 and step ST5 correspond to the overlap determination means, and step ST4, step ST6, and step ST7 correspond to the time axis vertical direction position determination means.

As described above, in this embodiment, when an event symbol is entered in the event symbol entry area 23a of the first column or the event symbol entry area 23b of the second column by the duplication determining means, it is determined that the event symbol has already been written. If it is determined that the event symbol overlaps with another event symbol, the column in which the event symbol is written in is made to be different from the column in which the other event symbol is written in the event symbol entry area 23. Event symbols This has the effect of preventing them from overlapping with each other.

The number of columns in the event symbol entry area 23 may be limited so long as it is easy to establish a correspondence between the entered event symbols and the horizontal axis 78 and the number of columns does not intrude into the entry columns for other items.
In this embodiment, there are three rows.

Further, in this embodiment, the event symbol entry area 23 is arranged on the horizontal axis 78 with the horizontal axis 78 of the two-dimensional chart recording area 20 as the time axis, but the vertical axis 76 is the time axis and the vertical axis 76 is the time axis. An event symbol may also be written above.

Also, as shown in FIG.
In ST6, an arrow 80 extending from the number written in the event symbol entry area 23b in the second column to the horizontal axis 78 is entered in the event symbol entry area 23a in the first column, and in step ST7, the event symbol in the third column is entered. From the number entered in the entry area 23c to the horizontal axis 7
The arrow 82 extending to 8 may be written in the event symbol entry areas 23a and 23b in the first and second columns. In this way, there is an advantage that the occurrence time of the event corresponding to the number written apart from the horizontal axis 78 becomes clearer.

The above-mentioned embodiment is merely an embodiment of the present invention, and various changes may be made to the present invention without departing from the spirit thereof.
