Abstract

PURPOSE:To eliminate a transfer time, to effectively execute a data processing of a high speed and a large capacity, and to simply and quickly execute a processing of a computer by constituting the system so that when the data receiving terminal is connected to the computer, a memory of the data receiving terminal can be accessed directly from a CPU of the computer. CONSTITUTION:When a data pager 2 and a computer 1 are connected by connector parts 1b and 2b, a memory 24 is detached electrically from a CPU by a separating circuit 25 by a signal S from a switch provided in the connector part or a control signal from the computer side, and enters under the direct management of a CPU 13. That is, the memory 24 is regarded as a part of a memory of the computer 1, read out directly and at any time by a second control means 19 in the CPU 13 without executing a data transfer which necessitates temporary accumulation in a second memory 14 between the data pager 2 and the computer 1, and a display of this data, a printer output or various data processings can be executed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transmission system for transmitting information from a data receiving terminal such as a data pager to a computer.

[0002]

2. Description of the Related Art Conventionally, when information is transmitted from a receiving terminal such as a pager to a computer, a serial interface circuit or a parallel interface circuit is provided and connected via each serial port or each parallel port to receive data. After once transferring the contents of the memory to the terminal to the memory of the computer, the CPU of the computer accesses the memory to perform display, print, and data processing.

[0003]

However, the data receiving terminal and the computer have to be connected using a cable. Also, a large-capacity memory for storing data in both the data receiving terminal and the computer was required. Transferring data from the memory on the data receiving terminal side to the memory on the computer side requires a program and CPU to transfer data to both the data receiving terminal and the computer, and transferring data takes a long time. It was inconvenient.

Further, the transferred data must be converted into a format (format) that can be easily handled by computer software, which requires a long time and is inconvenient. SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and a data receiving terminal which does not require a step of temporarily storing data transferred to a computer side in a memory in the computer when transferring data to the computer side. The purpose of the present invention is to provide an information transmission system between a computer and a computer.

[0005]

SUMMARY OF THE INVENTION The present invention provides a connector for electrically connecting to a computer in the form of an attachment, data receiving means for receiving information from outside, a memory for storing received data, A first control unit for controlling the data received by the receiving unit to be converted into a file and storing the data in the memory; and when connected to the computer, the memory is electrically disconnected from the first control unit. A separation circuit that enables direct access to the memory; and the first control unit includes a file conversion unit that stores the received data in the memory in a specific file format that can be directly accessed from a CPU of a computer. A data receiving terminal, wherein the received data is converted into a specific file format. The may be performed during data reception by the data receiving means. Also, the present invention is an information transmission system including the data receiving terminal and a computer including a second control unit having an operating system for reading data stored in the memory in the specific file format.

[0006]

When the data receiving terminals are not connected by a computer, they operate as complete systems independently. That is, the data receiving terminal stores data while converting the data into the predetermined file format in the first memory via the data receiving means for receiving information from the outside by the first control means having the predetermined program. The computer to which the data receiving terminal is not connected alone operates as a computer by itself.

Here, when the data receiving terminal is connected to the connector of the computer, the following operation is performed. At the same time as being connected by the connector section, the first memory is electrically disconnected from the first control means by the action of the separation circuit, and the first memory is directly under the control of the second control means on the computer side. to go into. That is, the first memory is considered part of the computer's memory, and the data in this memory is:
Direct display, printing, and data processing are performed as an OS file of the computer. That is, information can be transmitted without performing data transfer in the form of temporary storage in the second memory between the data receiving terminal and the computer.

Further, the data in the first memory is recorded in the same file format as the operating system of the computer, so that the processing on the computer becomes easy.

[0009]

1 and 2 show an embodiment of the present invention. 1 is a perspective view, and FIG. 2 is a block diagram. In FIG. 1, 1 is a computer, and 2 is a data pager as a data receiving terminal.

When the data pager 2 and the computer 1 are not connected and operate independently, the operation is as follows. The data pager 2 receives a radio wave from the antenna 21, and performs tuning, detection, and amplification in the radio reception circuit unit 22. In some cases, data decoding error correction is performed. CP
U23 converts the data from the wireless reception circuit 22 into a file format of a predetermined operating system (for example, MS-DOS) by the operation of the first control means 29 in the CPU, and stores it in the memory 24. Generally, the time required to convert the data to a file format is sufficiently shorter than the time required to receive the data. There is no big difference with the time to do. The data pager 2 can also display the data stored in the memory 24 on its own display.

The computer 1 alone operates as a computer. That is, the CPU 13 controls the memory 14, the display, the printer, and the like.
Here, when the data pager 2 is connected to the connector of the computer 1, the following operation is performed. That is, as shown in the block diagram of FIG. 2, when connected by the connectors 1b and 2b, the memory 24 is separated from the CPU 23 by the separation circuit 25 by the signal S from the switch provided on the connector or the control signal from the computer. Electrically disconnected C
It comes under the direct management of PU13. That is, the memory 24
Is regarded as a part of the memory of the computer 1, and without performing data transfer between the data pager 2 and the computer 1 that requires temporary storage in the second memory, The data is read out directly and at any time by the second control means 19, and the data can be displayed, output to a printer, or various data processing can be performed. Since there is no need to temporarily store the data in the second memory, the processing is performed. Time is short.

In this embodiment, a data pager for receiving information data from a radio wave is used as a data receiving terminal. However, another type of receiving terminal for performing data input using wired communication may be used.

A mark reader using an optical sensor or a card reader using a magnetic sensor may be used. Alternatively, a key switch may be used.

The connection connector between the data pager 2 and the computer 1 is, for example, PCMC1Aversion-1 (JE
This connector is specified by IDA version 4.1) (Fig. 3).

[0015]

According to the present invention, the following effects can be obtained.
The information data collected by the data receiving terminal is transferred when necessary, by inserting the data receiving terminal into the connector of the computer, in a format requiring temporary storage in the memory of the computer. Without being read directly by the computer. Therefore, since the transfer time in the sense as described above is zero, it is effective for high-speed and large-capacity data processing. Since the data stored in the first memory is in a file format that can be read directly from the computer side, the processing of the computer becomes simple and quick.
