Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document editing device, such as a Japanese word processor, which has functions such as document input, editing, and printing.

[Conventional technology]

Small document editing devices, such as personal Japanese word processors, which have become rapidly popular in recent years, are known as the Caliber McGraw-Hill Publishing Company, December 1, 1984.
As stated in the new product special feature in the 7th issue, RAM (R
andam Access Memory) Card (R
Also called AM pack or memory card. ). This RAM card is a sealed package of battery-backed static RAM, and is about the size of a business card to make it compact and easy to handle, and has a storage capacity of several kilograms or tens of kilobytes. Therefore, for example, a personal Japanese word processor can store several to several pages worth of documents.

By the way, since conventional document editing devices such as Japanese word processors are often used for business purposes, 5-inch or 8-inch floppy disk devices that can store large amounts of data are recommended as external storage devices for data. was used, and there was no one that used a RAM card as an external storage device. For this reason, a RAM card containing a document created using a personal Japanese word processor cannot be read by a conventional business Japanese word processor, resulting in a lack of document compatibility.

[Problem that the invention seeks to solve]

For example, in a document editing device such as a business Japanese word processor equipped with a RAM card access interface circuit, operability when inserting and removing a RAM card becomes a problem. An object of the present invention is to improve the operability when inserting and removing a RAM card.

[Means for solving problems]

In order to achieve this object, the present invention provides a document editing device such as a Japanese word processor for business use, in which a RAM is installed on the same surface as the external storage device, in the vicinity of the external storage device, and in parallel with the insertion port of the external storage device. A card insertion slot has been added.

[Effect]

Operability is improved by providing the RAM card insertion slot on the same side as the external storage device, near the same side and parallel to the insertion slot of the external storage device.

This RAM card access interface circuit 6
When an AM card is connected, the RAM in the RAM card can be read and written from the document editing device. The system memory 8, which temporarily stores document data and stores system control programs, is RAM or ROM (Read
0nly Memory>, and when it is configured only with RAM, the system control program is read out from the external storage device 4 as necessary and temporarily stored in the RAM.

Additionally, the system control program may be stored in the ROM.

FIG. 3 is a diagram showing a flowchart of starting the RAM card control program in the control device 7. That is, the control device 7 sets an address in the system memory 8 where information on the presence or absence of a RAM card is stored, reads the information, and determines whether a RAM card is connected. Next, if a RAM card is connected, the system is started according to the system control program for when a RAM card is connected, and if a RAM card is not connected, RA, M
Start the system according to the system control program for when no card is connected.

FIG. 4 is a diagram showing a flowchart when reading a document in the control unit [ff7]. That is, a storage device selection screen is displayed on the CRT display device 2.

Allows the user to select whether the document is stored in the floppy disk device 4 or in the RAM card 8. Next, a list of document names is read from the storage device corresponding to the input key and displayed on the CRT. The document name is displayed on the device and the corresponding document name is input. Then, the document with the input document name is transferred to the system memory 8. Note that the same sequence is used for registering one document.

Figure 5 is the control section! ! ! 7 is a diagram showing a flowchart when reading a document from a RAM card in step 7. FIG. That is, when a RAM card is selected as the storage device, the control device 7 provides a buffer area in the system memory 8 for data conversion. Read data from RAM card,
The read data is temporarily stored in the buffer area. Next, the data in the RAM card is converted into a usable data structure within the document editing device in the buffer area.

The data format of the RAM card compresses and stores document data so that a large amount of documents can be stored by making maximum use of the small memory capacity, while increasing the processing speed within the document editing device. This is because the document data format has redundancy.For example, the data format of a RAM card compresses character attribute information and expresses one character in about 2 bytes, but within the document editing device. In the data format, one character is expressed in about 4 bytes. The data in the RAM card converted into a data structure usable in the document editing device in the buffer area is transferred to a document area in the system memory 8. This document area becomes a document to be edited and proofread within the document editing device.

Reference numeral 20 denotes a printing device for printing the editing results, and 1 is, for example, a thermal transfer type printing device. Reference numeral 21 denotes a RAM card insertion slot, and by inserting a RAM card here, the edited result document is stored in the RAM card. For example, a RAM card can store about 10 pages of documents.

FIG. 10 is a diagram in which the RAM card shown in FIG. 8 is connected to a document editing device such as the business Japanese word processor shown in FIG. 5, where 17 is the RAM card and 22 is the business Japanese word processor. In such a document editing device, by inserting a RAM card into the RAM card insertion slot 5, the RAM card can be read and written by a document editing device 22 such as a business Japanese word processor. In other words, it becomes possible to temporarily record a document created with the personal Japanese word processor shown in FIG. You can use it as is on a business document editing device, or save it to an external storage device on a higher-end machine.

Furthermore, it can be edited again on a higher-end machine. Also.

Conversely, it is also possible to store documents created with a high-end document editing device on a RAM card, which can also be used in a personal Japanese word processor. Furthermore, thermal transfer printing devices are often used as printing devices for personal Japanese word processors, but this type of printing device has a slow printing speed and is not an impact printer, so it is difficult to print multiple pages at the same time. However, according to one embodiment of the present invention, the personal Japanese word processor Documents created with can now be used in a higher-end document editing device via a RAM card, making it easier to print at high speed, print multiple sheets at the same time, and add two figures. Further, since the RAM card insertion slot is provided near the external storage device and parallel to the storage device insertion slot, it is easy to insert and remove the RAM card, resulting in good operability.

In one embodiment of the present invention, the interface circuit 10 with the control unit is an example in which data is sent and received between the RAM card and the document editing device 22 in a parallel format; According to this embodiment, the transmission and reception may be controlled in a serial format.
The number of connectors connected to the interface circuit 10 with the control unit can be reduced.

〔Effect of the invention〕

According to the present invention, it is possible to easily insert and remove a RAM card in a document editing device such as a business type Japanese word processor equipped with a RAM card access interface circuit, thereby improving operability.
