However, when there is a rush of customers, it can take a long time to receive orders and the items ordered can be delivered, or items that are different from the ordered items may be delivered, leading to confusion. A method has been put into practice in which a customer service staff carries a terminal device and transmits data to a register or the like for processing by wireless data transmission (Japanese Patent Application Laid-Open No. 121473/1983). A method is also known in which data is transmitted using infrared light between a terminal carried by a customer service staff and an optical transmitter/receiver at a store such as a gas station (Japanese Patent Laid-Open Publication No. 72062/1983). . However, these methods were not satisfactory for processing large amounts of information quickly and accurately. Therefore, we proposed a method that transmits data in both directions by emitting infrared light between an optical transmitter/receiver connected via an interface to a terminal device or register held by a customer service worker and an IC optical transmitter/receiver installed on the ceiling. has been done. In that case, it is not limited to one-to-one communication between the ceiling device and the terminal device.
Regarding polling by the Otsuki side device, it is also possible to use a 1-to-N or 1-to-N communication mode.

Then, each block Lj is sequentially scanned and data is transmitted in a time-division manner.

ましくない。In order to carry out two-way transmission and reception between the mobile transmitter terminal, the mobile terminal carried by the Zunawara customer service staff, and the transmitter/receiver unit 1 installed on the ceiling, etc., each transmitter/receiver unit A transmission request signal is sent to the transmission terminal, but since it is executed in all directions, all the light emitting elements must be driven.3.The transmission and reception unit sends a transmission request signal in a time-sharing manner. Therefore, the light emitting element is constantly driven. As a result, the light emitting elements of blocks that do not contribute to data transmission are still driven, resulting in an enormous amount of power consumed by the transmitter/receiver. Since the light emitting device continues to emit light, it places too much burden on the circuit and shortens the life of the light emitting element.J: In order to reduce power consumption, the transmitter/receiver unit 1~ is divided into several blocks when viewed from the horizontal plane. This is also undesirable because it lowers the TRI level when the time division timing and the transmission timing of the transmitting terminal match.

あった。The reason is that the communication block is divided into blocks,

If done every second, one communication will have a maximum of T, D+1-,
This is because it takes 1: D+ t seconds to re-communicate when an error occurs. In this case, since the transmitting terminal constantly changes its position, there is a problem that communication establishment becomes extremely difficult.

The light-emitting element power supply of the requesting block is driven, and the light-emitting element power supplies of the other blocks are stopped to reduce the consumption type j). Further, when re-communication is required due to data failure, only the area within the block is driven to shorten the time required for communication.Next, the configuration of the present invention will be specifically explained based on the drawings.

It is equipped with an MPU that transmits data to the PU, checks received signals, and blocks communications. In addition, 14 is a power supply unit 1゜Figure 5 shows the timer 1 for transmitting and receiving data transmission.
1. The problem is when the terminal that is going to transmit among the multiple transmitting terminals 7 can get the timing to transmit, but this system uses the two signals ``RD'' and ``ACK'' sent from the transmitting/receiving units 1 and 2. I'm taking the timing.

る。As a feature of the present invention, polling from the conventional transmission/reception unit is replaced with polling from the transmission terminal of the terminal.Since communication is performed with the transmission/reception unit 1-, the power is turned off when communication is not necessary. 2. Communication is possible only with the transmitting terminal that has requested communication, which is efficient. In addition, the signal request signal from the transmitter terminal 7 is detected by the discrimination circuit installed in the transmitter/receiver unit 1-2, and the light emitting direction of the transmitter/receiver unit 1- is restricted to that direction, so the power consumption is reduced to 1/8 of the conventional one. A major feature is reduction.

The transmission fR request signal from one direction is amplified by the amplifier 15 in the I+1 circuit 9, and then detected by the output of the phase comparator 1G of 1] 11-.
At output No. 6, the output level is unstable due to reflection of infrared light on the spatial transmission path. , Therefore, taking into consideration the straight propagation of infrared rays from −10 to 8, the phase comparison of the block behind the transmission request block r? When the level of ii6 is the external sound level, it is the corresponding block, and the 1-[D power supply of the modulation circuit 8 is avoided. For example, when a transmission request signal is received from the A block and the -C1Δ block is desired to be driven to emit light, the situation is as shown in FIG. In Figure 8, block 1 on the back side of the transmission request side
Since the detection voltage of 1, F and ``is 1?'' level, the difference between the coarse level and the signal detection level becomes clear by appropriate settings, and the logic circuit using the truth table of - , the switching operation of the light emission takes place.

In this case, the light emitting elements of each block are not always driven, but the light emitting element power supply of the data transmission requesting block is driven based on the detected value of the light receiving phase comparator level of the data transmission requesting block and the opposite block. From Yonishi IC,
(Power consumption by stopping the light emitting element power supply of other blocks)
j can be reduced. Furthermore, when the data is bad and communication needs to be re-communicated, only the area within the block is driven for communication, which has the effect of significantly shortening the distance between the required parts.
