Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an I / O box device.
In particular, it is easy to carry with a simple circuit configuration and simple operation.
Between mobile terminals or between mobile terminals and personal computers
The present invention relates to an I / O box device that transfers data between the I / O box devices. [0002] In recent years, with the advance of semiconductor technology, electronic devices
The use of portability and portability has led to a new
Electronic devices with various uses are being developed. For example, in the past, warehouse inventory management and super
-Market product management or electricity and gas meters
When reading meter readings, the person in charge actually goes to the site and
Check the status of the warehouse, the product, or the meter,
By filling in data, you can collect data on site.
I was And there is only one sheet with the data
And collected by the operator,
Data, such as P / C)
Input is performed and data processing such as tallying is performed in P / C.
Had been. In this way, the data collected on site
In the past, when data was input to P / C etc.,
Can be used as child input / output data
You. However, recently, a stationary P / C has been developed.
Key to input data in place of such a data input device.
-Operation unit and storage unit for temporarily storing input data and data table
Indicator and a size and weight that can be easily carried
Portable data input / output terminal (mobile terminal)
Have been. This mobile terminal is a so-called handy
It is called Minal, and it manages inventory of the above warehouses and supermarkets.
Market product management or meter reading of electricity and gas
It is used for etc. [0005] These portable terminals use key operation according to the purpose.
Using Tsukube, the user brings it to the site, stocks, products
Direct data input while actually watching the situation or meter
It is possible to do. And input to the mobile terminal
To perform simple tallying on the spot using the collected data
Is also possible. Also entered using these mobile devices
Collected data has already been converted to data,
It is also possible to transfer data to C. This
In this way, input data collected by individual mobile devices
Data transfer.
The advantage of being able to collect data quickly and accurately
There is. Then, the data input to the portable terminal is
To transfer between mobile terminals or between mobile terminals
And P / C in many cases. Conventionally, between portable terminals or between portable terminals and P /
Performs data input / output processing with C to control data transfer.
There is an I / O box device as a device to control. This I
There are three types of data transfer mode using the / O box device
Yes, from mobile terminal to P / C via I / O box
Data transfer and P / C via I / O box
To transfer data to a mobile terminal,
From the sending end of the transmission data) to the mobile terminal via the I / O box.
Each data transfer to the slave (reception side of transfer data)
There is a seed transfer mode. Therefore, one I / O box device is used.
All three types of data transfer modes
In order to realize simple and easy operability, conventionally, I / O
Support by making the intelligent equipment itself intelligent
Data transfer control on the I / O box device side.
And it was resolved. [0009] However, this problem
In such a conventional I / O box device, the I / O box
By making the equipment itself intelligent,
Performs complicated data transfer control with easy operation for the user.
Mounted on an I / O box device
There is a problem that the number of parts increases and the cost increases.
Was. That is, the portable terminal described above and
When transferring data between P / Cs, the I / O box
Check data transfer mode, cable between mobile terminal and PC
Connection between the mobile terminal and P / C.
It is necessary to perform communication control necessary for data transfer. [0011] In addition, the data described above between the portable terminals is used.
When transferring, the I / O box is set to the data transfer mode.
Confirmation, power supply to each mobile terminal, or between mobile terminals
Check the line connection, etc.
Data transfer between the master and the receiving mobile terminal slave
It is necessary to perform communication control necessary for transmission. As described above, the conventional I / O box device
Is the transmission / reception side mobile terminal or P / C signal line.
Check connection status, power supply status, data transfer mode, etc.
The situation required for data transfer from the sender to the receiver.
Judgment as much as possible without user intervention
Because it is necessary to transfer data reliably by operation, CPU
(Central Processing Unit)
Had been planned. Therefore, the input of the I / O box device
In addition to the above CPU associated with the use of intelligent technology, various sensors and power
By mounting the power source unit etc. on the I / O box device,
As the number of parts increases and the I / O box device becomes larger,
In both cases, there was a problem that the cost was high. Eye of the invention
The goal is to provide a simple
Convenient operation between mobile terminals or between mobile terminal and P / C
I / O box for reliable data transfer
It is to provide a device. SUMMARY OF THE INVENTION The present invention relates to a plurality of portable devices.
