When the main body 1 is in the normal state, the process 70- shown in FIG. 3 is normally executed. First, the signal from the level sensor 9 is used to check whether rice is stored in the rice storage unit 2 above a predetermined level (1), and if it is below the predetermined level, the monitor lamp 2
5 is turned on to call attention to it, and 1 is set in register R8 (2). Subsequently, the value of the check counter CK, which represents the amount of rice discharged after the rice in the rice storage unit 2 becomes below a predetermined level, is checked (3) to a predetermined value V. If the amount has reached the above level, it is determined that there is no rice left and 1 is set in the register R1 (4). In addition, the above ■. The value given by is
When the level sensor 9 detects that the level is below a predetermined level, the amount of rice remaining in the rice storage section is estimated, and the amount is set within a range that does not exceed that amount.

On the other hand, if it is determined in step (1) that the rice is at a predetermined level or higher, the monitor lamp 25 is turned off and 5)
As well as clearing the check counter CK to 0 (6),
Set 0 to each of registers R8-R (7
).

Next, it is checked by the signal from the sensor 17 whether or not the wood receiver 4 is set in the specified position 8), and if the rice amount 4 is not set, then the measurement is completed and the rice is taken out. It clears the rice discharge amount display (display in step (37) described later) on the measurement display 23 and returns to the normal time display, and also clears the display counter DC-t-0 representing the display contents. Do (9
). Next, turn on the monitor lamp 26 (10),
The user is prompted to return the amount of rice 4 to the predetermined position, and 1 is set in register R2 (11).

On the other hand, if it is determined in step (8) that the wood receiver 4 is set in the predetermined position, the monitor lamp 26 = 7- is turned off (12), and 0 is set in the wood receiver register R2. (13).

Next, the time given by the timer 29 is monitored to determine the predetermined time period (in this example, from midnight to

1, that is, the amount of rice has not been set, the alarm device 38 is activated (33) to notify that metering and discharging is not possible, and the main flow is returned.

In addition, if it is not recognized that the rice is out of rice or the amount of rice is not set, the amount to be measured (1 to 5 go) input using the weighing key 22 is set to the weighing value register V and the weighing counter C (34); The electromagnetic rock 15 is energized for a certain period of time, and first a unit amount (1 cup) is discharged into the wood receiver 4 (35). Accordingly, after counting the weighing counter C by 11 and further counting the display counter DC by +1 (36
), the value of the display counter DC is displayed on the measurement display 23 (37). Next, the remaining amount of rice is checked by the signal from the level sensor 9 (38), and if the remaining amount is below a predetermined value, the check counter CK is counted by +1 (39). After this, check the value of the metering counter C (40), and wait until C=o, that is, the amount to be measured has been dispensed (Step 3).
5) Repeat operations from (40).

When the metered discharge associated with the input of the metering key 22 is completed, the mn-discharge amount stored therein is loaded from the memory 28 of the controller 21 to the register TV 41.
), add the total discharge amount given by the measured value register ■ to this TV 42), write this updated TV value again to the memory 28 as the cumulative discharge amount (42).
3), Main 70-Heritan.

On the other hand, if there is a call from the management source via the telephone line 35 while the main 70 is being executed, the routine shown in FIG. 5 is executed. First, the cumulative discharge amount is loaded from the memory 28 of the controller 21 into the register TV (51), and the value of this TV is transmitted from the modem 33 to the management source via the telephone line 1s35 (52). After this, you will be waiting for a reply from the administrator (5
3) When it is confirmed by the reply that the transmitted data has been received by the management source, the connection of the telephone line 35 (normal state) is cut off (54), and the main 70 is returned.

This embodiment operates as described above. Normally, the remaining amount of rice in the rice storage section 2 and the set state of the wooden receiver are checked, the status is notified by the monitor lamps 25 and 26, and the remaining amount of rice is set at a predetermined level. If the level is below, an order is output to the management source to replenish rice within a predetermined time period. If there is an input on the measuring key 22, the measuring rice 3 is operated to measure and discharge rice, and the amount of rice discharged is added to the stored cumulative discharge amount and stored in the memory 28. Rice storage section 2 during weighing
When the remaining amount of rice in the container is below a predetermined level, the remaining amount of rice to be discharged is counted by a check counter CK, and the counted amount of CK is a predetermined amount V. If the amount exceeds that level, it is determined that the rice is out, and from then on, it is impossible to measure until rice is replenished, thereby preventing empty weighing. Furthermore, if the wooden tray 4 is not set at the time of weighing, weighing is similarly disabled to prevent rice from scattering.

On the other hand, if there is a call from the manager via the telephone line, the integrated discharge amount is read out from the memory 28 and transmitted, and the usage status of the rice is reported. Communication with such management source is
This is limited to a predetermined time period when 113B is used less frequently.

Note that this invention is not limited to the above-mentioned embodiments, and various embodiments can be considered. For example, instead of using an electric means to measure the rice, it is also possible to use a widely used manual button type. In this case, the displacement of the measuring key or the measured rice can be detected to detect and integrate the amount of rice dispensed. Good. Further, the accumulated discharge amount can be programmed to be cleared when notified to the management source at intervals such as once a month, and can be given as the usage amount within a unit period.

[Effects of the Invention] The present invention is configured as described above, and includes means for detecting when the amount of rice remaining in the rice bin is below a predetermined level, and means for integrating the amount of rice metered and discharged from the rice bin. Since the system is equipped with a means for notifying the remaining amount of rice and reporting the cumulative amount to the management source via a telephone line, the following remarkable effects can be achieved.

It is possible to detect when the amount of rice remaining is low and notify the management to prompt the rice to be replenished, so it is always replenished without having to replenish rice, making it convenient to use.

The person in charge of the rice bin can receive the total amount of rice via telephone line, and can easily grasp the usage status of the consumer. especially,
If the rice seller puts rice into the rice bin and deposits it with the consumer, then if it is used for a service that collects payment for the amount of rice used, the managing company can keep track of the amount of rice used by the consumer. This makes it easier to collect payments.

In addition, with these services, distributors are able to establish new customers and stabilize sales volume, and consumers are also encouraged to purchase and install their own rice bins and manage their rice supplies. This eliminates the need to do additional work, resulting in a significant improvement in service.
