Abstract

PURPOSE:To enable direct connection to a telephone line by transmitting the output from the tone signal generating device to a station without using any acoustic coupling means. CONSTITUTION:In the reservation mode, the commodity code is inputted by a data input device 13. Then, the CPU12 discriminates and confirms the code, ad storages the code in the device 13. When ordering, a switch box 4 is set to the unit 1 side, and a memory change-over switch 18 is made in the on-line mode. Then the station is called, and the order is made by manipulating the reservation-call button, and later the content of the reservation is deleted. In case when the on-line mode is selected, the call to the station is made after confirming the switching of the switch box. And by inputting the commodity code by the data-input device 2, the direct ordering is made able to be confirmed by the operator through a sound discharger 7. Additionally, the interrupt processing is easily performed by operating the ten key. In result, the probability of a mul-function caused by noise is eliminated.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention is a system for placing an order for a product by sending a predetermined code corresponding to the product from a telephone device in the home to a computer system at a center (order receiver). The present invention relates to a data transmitting device used for product ordering, etc., in a system.

[Conventional technology]

Traditionally, there has been a system in which data is entered using a numeric keypad provided on a push-button telephone device and orders for products are made via a coupler device. This is done by combining a handset with a coupler device.

This coupler device tends to malfunction when used in a place with a high level of ambient noise, and also has drawbacks such as howling between the monitor speaker and the coupler microphone.

Furthermore, since it uses an acoustic coupling method, it is unreliable.
Another drawback is that the coupler device lacks versatility due to the existence of various types of handsets.

[Purpose of the invention]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a data transmitting device for use in ordering products, etc., which solves the above-mentioned problems by allowing the device to be directly connected to a telephone line.

[Structure of the invention]

The present invention includes a tone signal generating device and a data input device for sending a tone signal to a center, and enables the output of the tone signal generating device to be sent to the center without using an acoustic coupling means. A preferred embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a block diagram schematically showing an apparatus according to the present invention. In the figure, reference numeral 1 denotes a data transmitting device according to the present invention, which is configured so that line signals can be monitored with earphones 6 or speakers. 5 indicates the subscriber switched telephone network;
The line from the subscriber telephone switching network 5 is selectively connected to the telephone set 3 and the data transmission device 1 via a converter 4.

FIG. 2 is a block diagram of an embodiment of the present invention showing the internal configuration of the device shown in FIG. 1. In the same series, 2 is a data input device consisting of a numeric keypad switch, and the CPU 1
Connected to 2. The code read by the data input device 2 is processed by the CPU 12 and then sent to the tone signal generator 9. When a storage device is provided as shown in FIG. 2, the code is supplied to either the storage device 13 or the tone signal generator 9 via the memory changeover switch 18. Reference numeral 17 denotes a reservation call button, which is pressed when reading a code stored in the storage device 13. Further, the read code is transmitted to the tone signal generator 9
The terminal 10 is connected to the subscriber telephone switching network 5 via the terminal 10.

Further, the line signal amplified by the amplifier 14 is supplied to the speaker 7 or the earphone connection terminal 8.

Note that when a barcode reader is used as the data input device 2, it is also possible to generate an audio signal to confirm that the barcode has been read correctly. Although the power source for the device may be obtained by rectifying the AC line or using a battery, it is desirable to have a backup battery 11 in order to hack up the storage device 13. Note that the operating state of the circuit can be confirmed by pilot lamps 15 and 16.

Next, the operation of the circuit shown in FIG. 2 will be explained with reference to the flow diagram shown in FIG. First, in step 20, the memory selector switch 18 selects the reservation (local) mode or the online mode, and in the case of the reservation (local) mode, the product code is input using the data input device 1 in step 30. Thereafter, the code is discriminated and confirmed by the CPU 12 in step 40, and the code is stored in the storage device 13 in step 50. When ordering, after placing the converter 4 on the device 1 side (step 60), in step 70, the memory changeover switch 18 was set to online mode, and the center was called (in step 80, the reservation call button 17 was operated, and the An order is placed in step 90, and then the reservation details are deleted in step 100.

In that case, normally, each time you order a product, you operate the reservation call button 17 and send out information about the product code from the storage device 13, following instructions from the center, but it is important to send out information about all ordered products one after another. It is also possible to If the online mode is selected in step 20, the center is called after confirming that the converter has been switched in step 110, and the product code is entered manually using the data input device 2.
It is possible to order products directly without going through the storage device 13 while confirming with the sound emitting device 7.

Furthermore, if the user comes up with the idea of placing an additional order while the product code information is being sent through the storage device 13, interrupt processing can be easily performed by operating the numeric keypad. Although not shown, the device may be equipped with a handset instead of the earphones 6.

〔Effect of the invention〕

The present invention is as described above, and the tone signal corresponding to the product code input using the data input device can be sent directly to the telephone line, so it can be used in places with high ambient noise levels. However, there is no risk of malfunction due to noise being mixed in, the code can be transmitted correctly, and there is no need to consider versatility as in the case of a coupler device.
