Abstract

PURPOSE:To simply send/receive name card data in the case of one to lots of parties by converting name card data into an infrared ray signal so as to irradiate and to send data at once from one device to lots of devices. CONSTITUTION:When a transmission switch 11 is closed at the transmission of name card data, a CPU 13 reads transmission use name card data stored in a RAM section of a memory 14 and writes the data to a serial interface section 15. The written data are converted into serial data and sent to an infrared ray driving circuit 17 in the unit of times, an infrared ray is lighted from an infrared ray emitting element based on the content of data and is emitted externally through a diffusion lens 19. The infrared ray signal emitted externally radiates a light receiving element of plural automatic name card exchanging systems in a partitioned space. Thus, transmission reception of name card data of one to lots of parties are implemented. Since the infrared ray cannot passes through the partitioned wall, the secrecy is protected.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to exchanging business card contents, which are confidential contents, without leaking to the outside, and relates to a data communication device for transmitting and receiving business card data by an infrared signal in a partitioned space. Regarding

[0002]

2. Description of the Related Art Conventionally, business card data is exchanged by hand with paper on which a company name, an address, a name, and a telephone number are written. Further, by connecting both electronic notebooks and personal computers with a cable, wired business card data is exchanged. In addition, a wireless device is connected to an electronic notebook or a personal computer to exchange business card data by radio waves.

[0003]

Since the conventional exchange of business card data has been performed manually by one person to one person, the number of operations is increased when exchanging business cards for a large number of people, which is very troublesome. There is a drawback of this. Further, since the business card data exchange by wire is also performed by the one-to-one data transmission / reception of an electronic notebook or a personal computer, it is necessary to change the cable in the case of a large number of transmissions / receptions.
It has the drawback of being very time-consuming. Also, in the case of wirelessly exchanging business card data, it is not suitable for transmitting and receiving confidential business card contents, because it leaks to the outside of a space such as a reception room or a conference room due to the characteristics of radio waves. Therefore, an object of the present invention is to transmit and receive business card data without leaking confidential business card description contents to the outside of a partitioned space, and even when exchanging a large number, 1
It is an object to provide an automatic business card exchange device in which a plurality of devices can receive by one transmission.

[0004]

Therefore, in order to achieve the above-mentioned object, the present invention has a memory for storing business card data, a means for converting the business card data into serial data, and a serial data into an infrared signal. It is equipped with a light-emitting element and a drive circuit for emitting light from the light-emitting element, a lens for irradiating an infrared signal from the light-emitting element at a wide angle, a light-emitting element for receiving data irradiated with infrared rays, and a circuit for converting into business card data. In this space, one-to-many business card data transmission / reception by infrared signals can be automatically performed without leaking the contents of the business card to the outside.

[0005]

According to the present invention, converting business card data into serial data and converting the serial data into infrared rays and irradiating the data serves to transmit the data from one device to multiple devices at one time. It solves the problem that it takes a lot of time to exchange one-to-many business cards. In addition, the use of infrared signals for sending and receiving data is different from radio waves due to the characteristics of infrared rays, and those that block light have the property of not passing, so data can only be sent within a partitioned space, and it is confidential. It solves the problem of leakage of business card content, which is a common content.

EXAMPLES Next, examples of the present invention will be described with reference to FIGS. FIG. 1 is a system configuration diagram for performing business card data communication by infrared rays. 11 is CP
This is a switch for giving a business card data transmission command to U. Reference numeral 12 is a switch for giving a business card data reception command to the CPU. A CPU 13 reads a command stored in the memory by the CPU, sends the transmission business card data to the serial interface according to the state of the transmission switch and the reception switch, and stores the reception business card data converted by the parallel interface in the memory. Work. Reference numeral 14 is a memory in which commands to the CPU and business card data are stored. Reference numeral 15 is a serial interface for converting the data sent from the CPU into serial data. Reference numeral 16 is a parallel interface for converting data received from the infrared light receiving element into parallel data. Reference numeral 17 is an infrared light emitting element and an amplifier circuit which are turned on and off by serial data. Reference numeral 18 denotes an infrared light receiving element and an amplifying circuit that turn on / off the received infrared signal. Reference numeral 19 is a lens for diffusing the infrared rays to be emitted. Reference numeral 20 is a lens for collecting the irradiated infrared rays. FIG. 2 is a sequence diagram showing the operation of the device. FIG. 3 is a schematic diagram of an actual usage situation. Next, the operation will be described.

When transmitting business card data, the CPU first executes an initialization routine held in the ROM portion of the memory at the time of start-up accompanying the start of power supply to this device, and then the transmission switch and the reception switch. Will be in a standby state.
(Step 21) When the transmission switch is turned on, the CPU
Reads out the business card data for transmission held in the RAM section of the memory and writes it in the serial interface section (step 22). The written data is serially converted and sent to the infrared drive circuit in time units, depending on the content of the data. Infrared light is emitted from the infrared light emitting element and is emitted to the outside through the diffusion lens. (Step 23) The infrared signal radiated to the outside illuminates the light receiving elements of the plurality of automatic business card exchange devices in the space partitioned as shown in FIG. This has an effect that one-to-many business card data can be transmitted and received. In addition, infrared rays cannot pass through the partitioned wall, which is a security effect.

When receiving the business card data, the CPU first reads the R of the memory when starting up the power supply to the device.
The initialization routine held in the OM unit is executed, and then the transmission switch and the reception switch are in a standby state.
(Step 21) When the receiving switch is turned on, the business card data radiated to the light receiving element from the outside by the infrared signal is amplified by the amplifying circuit to be written into the parallel interface. (Step 24) The written data is converted into parallel data. The CPU reads the parallel-converted data and writes the business card data in the received data storage area of the RAM section of the memory.

[0009]

As described above, according to the present invention, by converting business card data into an infrared signal and irradiating it, the data can be transmitted from one device to many devices at one time. There is an effect that it is possible to easily send and receive business card data between a large number of people. In addition, the use of infrared signals for transmitting and receiving data has the property of blocking the light unlike wireless because of the characteristics of infrared rays, and since it has the property of not passing through, data can be transmitted only within a partitioned space, and it is confidential. It has the effect of preventing leakage of the contents of the name card, which is the content.
