Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention is a method for enabling an information provider (consumer) to select a desired product from product information provided using an information transmission medium such as a catalog. Enter the item number and order quantity,
The present invention relates to a data input device used to notify a product information provider of order information.

More specifically, the present invention provides a data input device that does not require the information provider to recognize the product information provider's telephone number when ordering information is notified to the product information provider.

[Conventional technology] As a method of selling products without a store, catalogs with external photos of the products, or leaflets with only the product name for products whose appearance is well-known, are distributed to consumers' homes, and then posted there. The customer selects the item they want from the listed product group, receives the requested quantity via postcard, telephone, or OCR (optical character reader) paper, and then sends it by post. There is a method of delivering products to each household by courier.

Among these communication methods, postcards are limited in the number of products that can be handled due to the small amount of information that can be transmitted, the slow transmission speed, and the high cost of transmission. In other words, we have no choice but to limit ourselves to products that have high unit prices and do not require freshness. Further, the communication method by telephone has disadvantages such as the possibility of trouble between the supplier and the consumer because there is no recordability.

As a way to improve these shortcomings, the product name is printed on OCR paper, and the order quantity can be written in numbers on the same paper as the product name.After writing the number, the paper is collected and read by OCR. There is a way. This method more than makes up for the shortcomings of postcards and telephone communication methods in terms of recordability, communication information, communication cost, and reading speed.

However, when numbers are written by hand and read by a machine, many numbers are unreadable, and great care must be taken to prevent stains and deformation of the paper surface. In addition, the OCR paper size is due to physical limitations of OCR (
It is determined by the number of reading sensors, entrance dimensions),
Even if you try to increase the number of listed product items, it cannot be changed easily.

Therefore, in order to solve these problems, a numerical key is provided, the numbers are converted into codes and stored in a storage means such as a semiconductor memory, and the numbers Q and C are converted into readable character patterns to confirm the entered numbers. A device that is equipped with a display unit that converts and displays the image is conceivable.

In such a device, numbers are input using numeric keys, so there are no individual differences. Furthermore, if a semiconductor memory is used as a storage means, it is possible to obtain a small size and a large capacity, so there are no limitations that OCR paper has.

The input information can be collected by placing the semiconductor memory in a removable case (hereinafter referred to as a memory card) and transporting it manually; or by placing the semiconductor memory inside the device. There is a method of transmitting the contents using a fixed communication line.

The method using a memory card is a method that digitizes OCR paper, and does not require major changes to the conventional non-store sales management method. On the other hand, the method of using communication lines is completely different from conventional methods and is superior in terms of speed and reliability of information transmission.

The apparatus described above has significant advantages in terms of quality in transmitting information, but there are also some problems that need to be solved in operation.

[Problems to be Solved by the Invention] When transmitting ordering information using a communication line, the wearing side must know the telephone number of the other party providing product information. The number of product M'r information providers increases as the number of product types increases, and their telephone numbers may also change. Accurate recognition of these phone numbers,
It is almost impossible to ask the information recipient to follow up on the changes, and therefore a means is desired for the information recipient to accurately report order information to the product information provider.

[Means for solving the problem] When using a memory card or communication line as an information transmission medium, the telephone number of the product information provider should be stored along with the product information (in the case of a memory card) or transmitted. (In the case of a communication line), when ordering information regarding the product information is transmitted to the product information provider, the telephone number is automatically read out and the call is made.

[Effect] As a result, even if there are many product information providers,
The provided product information and the corresponding telephone number are always stored together, and even if the telephone number changes, the product information provider will not be aware of this and will be able to place an order accurately. It became possible.

Next, the operation of the power supply circuit 119 will be explained.

When a battery is used as the power supply circuit 117, the comparison voltage VRI is the battery termination voltage (the lowest operating voltage of the load side circuit,
The voltage is set to be slightly higher than the voltage of the voltage comparison circuit 60 of the signal line 169.
An output of 2 would indicate that the battery is near the end of its life (eg, one week before the end of its life). Since the information immediately before the end of the battery life on the signal line 169 is transmitted to the center via the memory card 127, the center can deliver the battery for conversion to the orderer. The comparison voltage VR2 is a battery life end warning equal to the battery end voltage, and this signal causes the main control circuit 118 to inevitably enter a special operation and continue in that state thereafter. Comparison voltage VR

The output of the voltage comparator circuit 608 of 71 is applied to the contact circuit 605 to cut off the power supply, so as not to supply power to the power line 158, and switch to the power supply from the auxiliary battery 128 side.

The contact surface of this power supply line 158 will be briefly described. The contact circuit 605 consists of a contact part that makes contact between the power supply line 156 and the power supply line 610 and a control part that controls the contact part. 604 and the output of the voltage comparator circuit 608 applied via the signal line 171. Therefore, first, if a battery (main battery) capable of outputting an output higher than the final voltage is installed as the power source 117, The output of the voltage comparator circuit 604 on the signal line 170 becomes high level, and the contact circuit 605 becomes conductive. Therefore, the voltage comparison output of the trillion voltage comparison circuit 608, which is output via the signal line 171, also goes high.

After that, when the battery voltage of the power supply 117 drops below the final voltage VR2, the voltage comparison output of the signal line 170 becomes low level, but the battery voltage remains unchanged at that point.

Therefore, the output of the voltage comparator circuit 608 on the signal line 171 remains at a high level, and the contact circuit 605 maintains a conductive state.

Furthermore, the battery voltage of the power supply 117 drops and the voltage stabilizing circuit 6
When the output of 06 becomes lower than the comparison voltage VR3, the signal line 17
Since the voltage comparison output outputted to the terminal 1 becomes low level and the contact circuit 605 becomes non-conductive, the power supply line 158 quickly becomes a non-output state.

The reason why the power supply line 15B must be brought into a non-output state quickly is that in FIG.
The power source is a power line 1 backed up by an auxiliary battery 128.
72, and these three types of buffer circuits are 0MO3 (complementary) as actual circuit elements.If the input signal level is at the intermediate level,
It has a structure that allows a large through current to flow.

If the power line 158 were to drop slowly as the battery wears down, the voltage on the power line 172 would keep the input signal level of the interface circuit 124 at the intermediate level for an extended period of time, causing the backup The auxiliary battery 128 (FIG. 1) will quickly become exhausted.

Note that the common line 612 in FIG. 9 is omitted and not shown in FIG. 1. Further, the input of the interface circuit 124 is connected to the GND line through a pull-down resistor, and is fixed at the GND level when the power line 158 is in a non-output state.

FIG. 10 is a circuit configuration diagram showing a specific example of the boost power supply circuit 115.

660 is a power supply disconnection circuit controlled by the main control circuit 118 through the signal line 157, and only during communication.
By connecting the power lines 156 and 661, unnecessary power consumption is prevented.
652 is a square wave oscillation circuit, 653 is a logic inversion circuit, 65
4 is a logical product path, 655, 656.657 and 65
8 is a contact circuit, and 659 is a voltage stabilization circuit. The operation of these circuits will be explained below.

The main operation of the boost power supply circuit 115 shown in FIG.
59 outputs a constant voltage to the power supply line 154, and in order to roughly increase the voltage conversion efficiency, the input power supply line 6
The purpose is to select whether to boost the voltage twice or three times depending on the voltage of 61. The output VR4 of the comparison reference voltage generation circuit 650 is set to a voltage value that allows the voltage comparison circuit 651 to detect the input voltage when the output voltage during the double boost operation becomes lower than the desired output voltage. The contact circuit 655 is conductive when the input signal of the signal line 664 is at a low level, and is non-conductive when the input signal is at a high level. When the input signal of 664 is low level, it is non-conductive, and when it is high level, it is conductive. The contact circuit 657 operates in the same manner as 655, and the contact circuit 658 operates in the same manner as 656.

In the triple boost operation, when the contact circuits 656 and 657 are first conductive and the contact circuits 655 and 658 are not conductive, the power supply line 66
1 → diode D50 → capacitor C50 → disconnection circuit 6
56→common line 662, capacitor C50 is charged. Next, when the contact circuits 655 and 658 are conductive and the contact circuits 656 and 657 are non-conductive, the path is the power line 661 → disconnection circuit 655 → capacitor C50 → diode D51 → capacitor C51 → disconnection circuit 658 → common line 662. The capacitor → J-C51 is charged to a voltage twice the input voltage (more precisely, the voltage after subtracting the voltage drop in the contact circuit and the diode). Next, when the state of each contact circuit returns to the same state as the beginning, in addition to charging the capacitor C50, the power supply line 66
] → Disconnection circuit 657 → Capacitor C51 → Diode D
52→Capacitor C52→Common line 662, the capacitor C52 is charged to a voltage three times the input voltage (more precisely, the voltage after subtracting the voltage drop in the contact circuit and the diode).

Thereafter, the above operation is repeated.

output of pin 1) becomes low level, and contact circuits 657 and 6
This is done when 58 is controlled to a quiescent state, and initially when surface circuit 655 is non-conducting and 656 is conducting, capacitor C50 is charged to the input voltage. Next, when the contact circuit 655 is conductive and the circuit 656 is non-conductive, a voltage obtained by adding the voltage accumulated in the capacitor C50 to the input voltage is charged to the capacitor C52 through the diode D53 (the diode D53 is charged during double field pressure operation). This is a bypass diode for halving the voltage dropped by the two diodes D51 and D52). This operation is repeated thereafter.
