Abstract

PURPOSE:To raise the operability of a document processor by easily switching typewriter mode and word processor mode by one-touch push of the input key of a cursor pad set near the typewriter. CONSTITUTION:A cursor pad CP is provided with keys K1-K6 to move cursor on CRT in the direction of wedge mark, HELP key 7 to be used when knowing the procedure of operations, BD key K8 to move the cursor to head of a document, ESC key K9 to be used when interrupting various functions of word processor mode, and CODE key K10 to indicate specific functions by combination and pushing of English and letter keys. When ESC key K9 is pushed by the forefinger and CODE key K10 is pushed by the thumb at the same time, switching of typewriter mode and word processor mode can be made by one-action.

Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a document processing device for creating and editing documents.
In particular, the present invention relates to a document processing device as a typewriter attachment device that can be operated in conjunction with a typewriter device.

[Prior art]

Conventionally, a document processing device as a typewriter attachment device generally includes a typewriter T, as shown in FIG.
It consists of a cursor pad CP placed right next to the typewriter TV, a floppy disk drive FD on the attachment body side, and a CRT (cathode ray tube) display device. In particular, if a mode switching switch SW is provided on the attachment body side, and the typewriter TV is operated as a conventional tie 7' writer, the switch SW is set to the typewriter (TV) side, and on the other hand, when the typewriter TV is operated as a word processor. The switch SW is set to the word processor (wp) side. The operator normally creates and edits documents by operating the keyboard of the typewriter TV and the cursor pad CP right next to it.

In this way, this type of device can be used to type and print documents easily and easily as a conventional typewriter device.
It can be used both for creating and editing large documents with word processing capabilities. However, when using it as a typewriter, it is almost always necessary to interrupt the actual operation of the machine as a word processor when there is an urgent need to type a document such as a handwritten note.

However, when switching, in the conventional document processing apparatus, as shown in FIG. 1, it is necessary to reach up to the attachment body and switch the switch SW, which does not provide good operability.

〔the purpose〕

SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object of the present invention is to eliminate the conventional mode changeover switch SW and instead use the input key on the cursor pad to switch between typewriter mode and word processor mode. An object of the present invention is to provide a document processing device that is configured to perform the following operations and has improved operability.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 2 shows an example of the arrangement of the cursor pad of the document processing apparatus of the present invention. Here, keys 1 to 6 with arrow or wedge symbols are keys for instructing cursor movement on a CRT display device (not shown).

In addition, the key labeled "HELP" (7) is a key used when the operator wants to know the operating procedure, and the key labeled "B, D" (8) quickly moves the cursor to the beginning of the document. This is the key used when

Further, the key 9 labeled "ESC" is originally a key used to interrupt various functions of the word processor mode (hereinafter referred to as word processor mode). “C0D
The key K1.0 marked with "E" is originally a key that is pressed in combination with an alphanumeric character key on the typewriter to instruct a specific function.In this example, as described later,
9 on the Esc key with your index finger and C0DE key KI with your thumb
By pressing O at the same time, you can switch between typewriter mode and word processor mode with one touch.

FIG. 3 shows an example of the circuit configuration of the cursor pad shown in FIG. 2.

As shown in the figure, ten press keys Kl to KIO, pull-up resistors R1 to RIO for each key,
An inverter INV connected to the key KIO, an OR gate G1 that ORs the key 9 and the inverter INV, and an OR gate G2 that ORs the key 9 and the key KIO.
It consists of a flip-flop F/F connected to the output terminal of OR gate G2.

FIG. 4 shows the truth values between keys 9 and KIO and OR gates GI and 02. As shown in Figure 4, ESC
Only when keys 9 and (!ODE key KIO are pressed (ON)), the output of OR gate G2 generates a negative pulse (L), and the output mode of flip-flop F/F is reversed. The typewriter mode and word processor mode are switched by the output signal REDY obtained from the F/F.For example, when the signal REDY is LOW
Activate the original typewriter function when level.

That is, the output signal R[DY
is the output signal R of the conventional changeover switch SW shown in FIG.
Just replace it with EDY. Furthermore, since the conventional functional signal group remains as is as shown in FIG. 3, there is no need to modify the conventional circuit in this respect.

〔effect〕

As explained above, according to the present invention, it is possible to easily switch between the typewriter mode and the word processor mode by pressing the input key on the cursor pad located near the typewriter. This eliminates the need for a mode selector switch on the typewriter attachment body, resulting in improved operability and ease of use.
