FIG. 7 is a flow chart showing the operation of the word processor main body 10 in the word processor with a manual printer, and FIG. 8 is a flow chart showing the operation of the manual printer 14. First, when storing the manual printer 14 in FIG. When the voltage level of the power supply unit 31 monitored through the power supply voltage detection unit 32 in FIG. 6 falls below a predetermined print drive voltage required for driving the thermal head 29, the control unit 25 sends “charge request ON” via the interface 27. "
A signal is sent to the word processor body 10 side (step
B1, B2). Then, the control unit 20 of the word processor main body 10 in FIG.
The "charge request ON" signal of the manual printer 14 is input via 22 to activate the charging circuit 24 (steps A1, A2). Then, the charging voltage signal output from the charging circuit 24 is input to the manual printer 14 side via the connectors 15 and 16, and charging of the power supply voltage in the power supply unit 31 is started.

When the voltage level monitored by the power supply voltage detection unit 32 reaches a predetermined voltage level in the charging state of the manual printer power supply unit 31, a "charge request OFF" signal is sent from the control unit 25 via the interface 27 to the word processor main unit 10.
Sent to the side (step B1 → B3). Then, the control unit 20 of the word processor body 10 inputs the "charge request OFF" signal from the manual printer 14 via the interface 22 and stops the charging operation by the charging circuit 24 (step
A1 → A3).

Here, when the operator operates the transfer key 11a in the key input unit 11 in order to transfer the document created by the word processor main body 10 as print data to the manual printer 14,
The print data stored in the input data storage unit (not shown) in the word processor main body 10 is patterned in the character data generation unit 21, and the control unit 20 transfers the pattern data to the interface
The output is transferred to the printer 14 side via (step A4 ~
A6). Then, in the manual printer 14, the print data output and transferred from the word processor body 10 is input to the control unit 25 via the interface 27 and stored and stored in the storage unit 26 (steps B4, B5).

On the other hand, when, for example, a character input key is operated in the key input unit 11 of the word processor body 10, the key input data is stored and stored in the input data storage unit (not shown) through the control unit 20 (steps A4, A5). → A7).

In this way, the print data is transferred from the word processor main body 10 to the storage unit 26 of the manual printer 14 and stored, and the power source unit 31 is fully charged, as shown in FIG. Is removed from the printer storage unit 13 of the word processor main body 10, its start key 17 is pressed, and the print mechanism 18 at the lower end of the printer is brought into contact with the recording paper A and moved in the X direction. An encoder pulse corresponding to the movement amount of is output to the control unit 25 (steps B6 and B7). Then, the control unit 25, based on the encoder pulse from the encoder 30, the print data stored in the storage unit 26,
One line corresponding to the number of print dots of the thermal head 39 is read, and the thermal head 29 is read through the head driver 28.
Transfer printing is performed on the recording paper A (step B8).

At this time, the control unit 25 counts the one-line printing operation, and determines whether or not the printing is completed depending on whether or not the count data reaches the number of one character line (step B
9, B10). That is, when the print quality of one character of the thermal head 29 is 24 dots (full-width), the printing data for one line is transferred and printed by repeating the one-line printing process for 24 times (step B7). ~ B10).

Therefore, according to the word processor with a manual printer configured as described above, the manual printer 14 is installed in the word processor main body.
With the printer mounted on the printer 10, print data created on the word processor side is sent to the printer 14 via the connectors 15 and 16.
Since the data can be transferred to a storage device and stored in the storage unit 26, it is possible to easily perform a print moving operation manually without the need to provide a code for transferring print data between the word processor body 10 and the manual printer 14. Become.

Further, since the power supply voltage of the manual printer 14 is automatically charged in the housed state in the word processor body 10 as described above, the power supply voltage is not required in addition to the data transfer code, and easily transferred to any place. It becomes possible to print.

[Advantages of the Invention] As described above, according to the present invention, in the state where the first connector means provided in the apparatus main body and the second connector means provided in the manual printer are connected to each other, the apparatus main body Since the data input by the side is transferred to the manual printer side through each connector means and stored in the second data storage means of the manual printer side, the manual operation is performed based on the stored data. It is possible to print.

Further, according to the present invention, when the respective connector means are connected, the manual printer detects the state of the power supply voltage of the second power supply means by the power supply voltage detection means provided in the manual printer, and detects the state. If the generated power supply voltage is lower than the predetermined power supply voltage, the charge request output means outputs a charge request signal to the device body via the connector means, while the device body outputs the charge data to the device body. The presence / absence of the charging request signal is discriminated by the charging request discriminating means provided in the main body, and the charging voltage transmitting means determines the charging voltage from the first power source means in accordance with the discrimination of the presence of the charging request signal. Since it is sent to the power supply means, there is an advantage that good quality printing can always be performed under the condition of a sufficient power supply voltage.
