The storage means 6 stores the control procedure of the means 4.

Here, the storage means 6 is a ROM (Read Only Memo) storing the operation procedure of the control means.
ry) 6A and RAM for temporarily storing transmission / reception data
(Random Access Memory) 6B.

The communication control means 3 is connected to the communication line 8 and controls communication, and converts communication data from the communication interface 3A into digital signals and converts communication data to the communication interface 3A into analog signals. And a communication modem 3B for conversion.

The key input means 1 comprises a character / symbol input key such as an alphabet key, a key for instructing the operation / operation of the printing means 5, and a key for instructing data transmission. A liquid crystal display is generally used as the display unit 2, but the display unit 2 is not limited to this. Key input means 1
The display means 2 is installed on the upper surface of the main body as shown in FIG.

Then, as shown in FIG. 2B, a serial connector 3C for connecting to the communication line 8 is provided on the rear surface of the main body.

The printing means 5 comprises a carriage 5B carrying a print head 5A as shown in FIG. 2 (A).

Further, the communication interface is provided with a parallel interface for receiving data transfer from the higher-level device, and a print data expansion unit for expanding the print data from the parallel interface into dot data and storing the dot data in the storage means is provided. There is. The parallel interface 7 includes a parallel connector 7A for connecting to a personal computer or the like.

The control means 4 is a CPU (Center).
al Processing Unit: central processing unit) is used. The control means has an exclusive control function of controlling so as not to accept print data from the host device when a communication mode setting command for data communication is output from the key input means.

Next, the operation of this embodiment will be described in detail with reference to the flowchart of FIG.

(1). The operator uses the key input means 1 to set the communication mode.

(2). The CPU 4 checks whether or not the specific communication mode is set (step S in FIG. 3).
1) If it is determined that the specific communication mode is set, the process proceeds to the next process (3).

(3). The operator inputs the transmission data using the key input means 1 (step S2 in FIG. 3).

(4). The CPU 4 displays the transmission data input from the key input means 1 on the display means 2 and stores the display content in the RAM 6B (step S3 in FIG. 3).

The operator can confirm whether or not the input is made correctly by looking at the contents displayed on the display means 2. If the input is wrong, the key input means 1
You can correct the input contents using.

(5). When the operator finishes inputting the transmission data, the operator instructs the key input means 1 to start communication. Specifically, the "communication" key of the key input means 1 is pressed.

(6). When the CPU 4 receives an instruction to start communication from the key input means 1, the CPU 4 outputs the contents stored in the RAM 6B to the communication modem 3B (step S4 in FIG. 3).

(7). The communication modem 3B converts the contents stored in the RAM 6B into analog data and outputs it to the communication line 8 via the communication interface 3A.

(8). When receiving from the communication line 8, the communication interface 3A outputs the received data to the communication modem 3B.

(9). The communication modem 3B converts the received data from the communication interface 3A into digital data and notifies the CPU 4 of it.

(10). Upon receiving the reception notification from the communication modem 3B (step S5 in FIG. 3), the CPU 4 displays the content of the digital data from the communication modem 3B on the display means 2 and stores it in the RAM 6B (step S6 in FIG. 3).

When the received data stored in the RAM 6B reaches a certain amount (for example, the amount of one block sentence), the next process (1
Go to 1).

(11). The CPU 4 analyzes the received data and determines whether or not to print (step S in FIG. 3).
7).

When the CPU 4 requires printing, the R
The contents stored in the AM 6B are sent to the printing means 5 and printed by the printing means 5 (step S8 in FIG. 3).

When the CPU 4 does not need to print,
The process moves to the next process without printing.

(12). The CPU 4 analyzes the received data and determines whether the reception is completed (step S9 in FIG. 3).

When the CPU 4 determines that the reception is not completed, it returns to the process (8).

When the CPU 4 determines that the reception is completed, it proceeds to the next process (13).

(13). The CPU 4 determines whether or not there is a request for ending the communication mode (step S10 in FIG. 3),
If it is determined that there is no end request, the process returns to the process (2).

On the other hand, when the CPU 4 determines that there is a communication mode end request, the CPU 4 ends the communication process.

The operator makes a request for ending the communication mode by using the key input means 1.

Further, the data received via the parallel interface 7 can also be transmitted to another device via the communication line 8.

If the communication mode is not set,
It functions as a normal printer and prints the data received via the parallel interface 7.

[0052]

Since the present invention is constructed and functions as described above, according to the present invention, data can be transmitted / received and printed by only key operation, which enables transmission without connecting a plurality of devices. It is possible to provide an unprecedented excellent printer device in which data creation, transmission processing, reception processing, and reception data printing can be performed individually and easily.
