Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a cordless printer /
Regarding information equipment that employs general cordless output devices such as facsimiles and general cordless storage devices such as cordless floppy disks / hard disks, especially for editing data, then registering for storage, clear copy, confirmation For information devices to print for.

[0002]

2. Description of the Related Art Conventionally, in this type of information processing apparatus,
The document registration processing and the printing processing are handled as separate procedures, and the printing operation is performed after the registration in the external storage device is completed, or the registration operation is performed after the printing is completed.

When it is attempted to both register an input or edited document in an external storage device and print it in a printing device, conventionally, a registration key is first input to display a registration name input screen. When the registered name is entered on the screen and the enter key is entered, registration processing to the external storage device is performed.

After completing the registration process, press the print key to
Display the print setting input screen. When the print setting is input on the screen and the enter key is input, the print processing to the printing device is performed.

[0005]

However, in the conventional information processing apparatus, when the volume of a document that has been input or edited is large, the information is registered in the floppy disk device, which is one of external storage devices, or the printer device. Printing to took time.

In the prior art, since the registration and the printing are separate operations, the printing operation is performed after the registration operation, and the printing operation can be performed without waiting for the time to register in the floppy disk device. There wasn't.

On the contrary, if the printing is performed first, the printing speed of the printer is slower than the registration speed of the external storage device, so that the registration cannot be done without waiting a longer time.

Further, when printing is performed, the registration may be forgotten due to a human mistake. With the spread of word processors, the created documents are often diverted, and registration and printing are often performed at the same time, and the above-mentioned inconvenience has become noticeable.

Particularly, in the past, even though the data to be printed and the data to be registered are the same in a cordless printer / cordless floppy disk of a word processor, printing (control command + print data transmitting operation to the printer) operation and registration (floppy) are performed. Control command to disk +
Since the operation of transmitting the registration data) was separately given to the user, it was not possible to perform both printing and registration with one operation.

In simultaneous transmission, printing / printing is possible with a single operation.
Since registration was done at the same time, it was not possible to print / register only.

In the above technique, since the print logic and the registration logic are activated respectively in the conventional technique, the (registration control command + registration data) buffer and the (printing data) are registered despite the fact that the print data and the registration data are the same. A separate buffer for control commands + print data was secured, resulting in inefficient use of RAM.

In the prior art, when there is only one transmission port, it is necessary to transmit the registration data after transmitting the print data, or vice versa, that is, serial processing is performed, so that it takes time to print / register (printer. And the floppy disk did not work at the same time). Further, even if there are two transmission ports, it is difficult to simultaneously transmit data due to the cross-linking of data (it is necessary to provide a threshold or the like).

The present invention has been made in view of such circumstances, and solves the above-mentioned problems by simultaneously performing registration and print input operations.

[0014]

According to the invention of claim 1, data is registered, the registered data is simultaneously transmitted to a printing machine and a floppy disk, and the data is registered to the floppy disk at the same time. A data registration and printing method of an information processing apparatus, wherein document data is printed by the printing machine.

Is a data registration and printing method of the information processing apparatus, characterized in that any one of printing is selected.

According to the third aspect of the present invention, data is registered, the registered data is simultaneously transmitted to the printing machine and the floppy disk, and the floppy disk is controlled by using a common control buffer for registration and printing. Document data is registered at the same time, and at the same time, the data is printed by the printing machine.

According to the fourth aspect of the present invention, data is registered and simultaneously transmitted from the common transmission means to the registered data printing machine and floppy disk, and the document data is registered to the floppy disk. A data registration and printing method of an information processing device, wherein data is printed by the printing machine.

[0018]

According to the first aspect of the invention, printing and registration can be performed by a single operation in, for example, a word processor equipped with a cordless printer / cordless floppy disk.

According to the second aspect of the invention, in the simultaneous transmission system, for example, a word processor, only printing or registration can be performed.

According to the third aspect of the present invention, in the above technique, the (registration control command + registration data) buffer and the (printing control command + print data) buffer are shared, so that the RAM is efficiently used. → Cost reduction is possible.

[0021] According to the invention of claim 4, one transmission port can secure a transmission speed equivalent to the case of simultaneous transmission from two transmission ports, and there is no fear of crosstalk.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in the drawings. The present invention is not limited to this.

FIG. 1 shows a block diagram of the present invention.

The display device 1 displays the input sentence.
The CPU 12 controls the operation of the subject. The text memory 2 is a buffer holding the input text. The keyboard 3 is used by the user to input a text and to specify printing / registration. The printer 4 prints a character string by transmitting a control command and a character string from the main body. FD
The D (floppy disk drive) 5 registers a character string by transmitting a control command and a character string from the main body.

The transmission circuit 6 and the transmission port 7 transmit data from the main body to the printer / FDD. The transmission circuit 6 and the transmission port 7 are activated by the print / registration data transmission logic 9. The print / registration data generation logic 8 is a logic for generating data to be printed / registered from the document memory. The print / registration data transmission logic 9 transfers the data generated by the print / registration data generation logic 8 to the printer / FD.
This is the logic to send to D. Send buffer 10
Is a buffer for generating / transmitting transmission data.
A print / registration control flag (ITFLG) 11 represents user designation of print / registration (1: print / registration 2: print
3: Registration).

FIG. 2 shows how data is transmitted from the word processor (host) 12 to the printer 4 / FDD 5, for example.

Data is transmitted from the transmission port 13 of the word processor 16 to the reception port 14 of the printer 4 and the reception port 15 of the FDD 5.

FIG. 3 is a schematic flow according to the designation from the keyboard of the user.

When the user performs a key operation to select both print / registration, ITFLG is set to 1, print only 2 is set, and only registration is set to 3 and then the print / registration data generation logic 8 is activated, and then printing is performed. / Send by activating the registration data transmission logic 9. The print / registration data generation logic 8 and the print / registration data transmission logic 9 will be described in detail later.

FIG. 4 is a flow chart for explaining the print / registration data generation logic 8. First, variables / pointers will be described.

A character string is stored as a 2-byte code in the document memory, the pointer BSTART indicates the beginning of a sentence, and the pointer BEND indicates the end of the sentence. BPNT is a pointer that moves on the text memory (see FIG. 6). The pointer SSTART indicates the beginning of the transmission buffer, and SPNT
Is a pointer that moves in the send buffer. The print command is a command for specifying printing, and the registration command is a command for specifying registration and has a length of 2 bytes. The character string start code / character string end code is a command indicating the start and end of the character string, and has a length of 2 bytes (see FIG. 7).

A description will be given according to the flowchart of FIG.
First, in step S10, BPNT / SPNT is initialized. Next, ITFLG (print / registration control flag) is detected (step S11). If this is 1 (print / registration), steps S12 and S15 are selected and the print / registration command is set in the transmission buffer (FIG. 5). 2 (print)
In this case, the print command is set in the transmission buffer (step S13, FIG. 5). In the case of 3 (registration), a registration command is set in the transmission buffer (step S14, FIG. 5). After that, the character string start command is set (S16), and the data from the beginning to the end on the sentence memory is set in the transmission buffer (steps S17 to S1).
9), set character string end command (step S2)
0). Here, the transmission buffer serves both for printing and for registration, and as a result, effective use of the RAM area is realized.

Next, the print / registration data transmission logic in FIG. 3 will be described.

FIG. 8 is a flow chart showing the processing on the main body side during transmission. Here, the print / registration simultaneous transmission process will be described (see FIG. 7).

As an outline, the contents of the transmission buffer are divided into N bytes each, set in a transmission packet buffer (size N bytes) (FIG. 11-), and sent in the order of print → registration → print → registration.

Next, a detailed description will be given according to the flowchart of FIG.

S81: The pointer (SPNT) of the transmission buffer (FIG. 7) is set to the beginning of the character string.

S82: The head of the transmission packet buffer is set in the transmission packet buffer pointer, and BSUM (counter for transfer control from transmission buffer to transmission packet buffer) is processed to 0.

S83: The transmission packet buffer pointer for setting the print command (2 bytes) is set to 2UP at the head of the transmission packet buffer. 2 up BSUM.

S84 / 85/86: BSUM = N-2,
That is, the contents of the transmission packet buffer are transferred to the transmission packet buffer until the space of the transmission packet buffer becomes 2 bytes or the transfer data (on the transmission buffer) becomes the character string end command. S87: In the case of the character string end command, the character string end command is directly transferred to the transmission packet buffer (see FIG. 11-
).

S88: If there are 2 bytes in the space, set the packet END command in the space (FIG. 11-).

S89: Contents of transmission packet buffer (N
Byte) (print packet data). Here, the specific contents of the sending process will not be mentioned.

S8A: The print packet data in the transmission packet buffer is converted into registration packet data. Specifically, the print command at the head of the transmission packet buffer is replaced with the registration command.

S8B: Contents of transmission packet buffer (N
Byte) (registered packet data). Here, the specific contents of the sending process will not be mentioned.

S8C: Pointer on transmission buffer (SPN
When the content indicated by T) is a character string end command, that is, when the print / registration packet transmission for all data ends, the transmission processing ends. If the content pointed to by the pointer on the transmission buffer (SPNT) is not a character string end command, that is, if there is still untransmitted data, the process returns to S82 and transmission of the remaining data is continued.

Next, the receiving process on the printer side will be described.

Data transmission from the main body side is performed in 2 bytes, and when this reaches the reception port 14 of the printer 4, a reception interrupt occurs and the printer side can extract 2 bytes of data. Since the contents of this processing are not directly related to the present invention, a detailed description will not be given here. FIG. 10 shows an FL indicating that the extracted data is set in JDATA (a 2-byte work area for holding the received data) (step 81) and the data is received.
AG (JINTF) is set to FF (step 82).

FIG. 9 shows the main processing on the printer side. FIG. 12 shows a packet receiving buffer (printer buffer) on the printer side. The details of the flowchart in FIG. 9 are as follows.

P1: reception interrupt flag (JINTF)
Is initialized to 00 P2: Print packet data receiving flag (JUSINT
YU) is initialized to 00. Initialize printer buffer pointer (points to the beginning of the printer buffer) P3 / 4/5/6/7: If there is no reception, keep waiting for reception. Received (JINTF = FF), JIN
Drop TF to 00. If it is the first reception at this point, it is judged whether the received data is a print command. If the command is not a print command (predicted as a registration command), the process returns to waiting for reception. Keep waiting until you receive a print command,
When the print command is received, the status is set to receive print packet data. (JUSINTYU = FF) P8 / 9/10/11/12/13: Unless the received data is a packet END command or a character string end command here, the received data is stored in the printer buffer and the packet END command or character string end is stored. When the command is received, the data up to that point is output. Detailed contents of the data output process to the printer are omitted here since they are not directly related to the present invention.

When an error (paper out / paper jam, etc.) occurs in the printer, ERROR (a flag indicating whether or not an error has occurred) is turned on, and the output processing for the subsequent received data is skipped. In other words, the error processing can be absorbed in the output processing phase and does not affect the overall processing flow, and therefore will not be described in detail here.

Since the processing on the FD side is the same as the processing on the printer side, its explanation is omitted.

As a result, the entire processing is performed in parallel as shown in FIG. 13 (the FD outputs the received data while the main body transmits the print data and the printer receives the data). Therefore, while the main body transmits the registration data and the FD receives the data, the printer outputs the reception data), and the same speed as in the case of simultaneous transmission can be secured. Further, since the print data and the registration data are not transmitted at the same time, there is no concern about crosstalk.

[0053]

According to the present invention, the cordless printer / cordless floppy disk of the conventional word processor is printed (control command + print data transmission operation to the printer) and then registered (control command + registered data on floppy disk). It was necessary to perform two operations, ie, the operation of sending the data) or the printing after registration. However, by sending (control command + data) to the printer and the floppy disk in one operation, Enable printing / registration with one transmission operation.

In the above technique, only registration / printing can be performed by user's designation.

In the above technique, by sharing the (registration control command + registration data) buffer and the (printing control command + print data) buffer, it is possible to efficiently use the RAM and reduce the cost.

The print data and the registration data are divided into packets and alternately transmitted to prevent crosstalk and to secure the processing speed equivalent to that in the case of simultaneous transmission.
