DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application of the Present Invention The present invention relates to a data communication terminal that is used by switching the connection to a telephone line to a telephone using a switch.

<Prior Art> When one telephone line is used for both phone calls and data communication, conventionally, a data communication terminal 1 having a configuration as shown in FIG. 4 is connected to telephone line terminals L1 and L2 and a telephone device. A manual switch 2 is provided between the terminals and the switch 2 to switch to the telephone device side in the case of a call using the telephone device, and to switch to the variable WA @ station 3 and data processing unit 4 side in the case of data communication.

Therefore, for example, in a store, etc., when people are present, the switch 3
Switch to the telephone device side so that it can be used for making calls or receiving N calls, and when there is an incoming call for data communication from the center etc., the person answers once with the telephone tl position and then switches. The switch 2 is switched to the modem 3 and data processing unit 4 so that data communication from the center etc. can be automatically performed at night when people leave the store or other premises.
to the modem 3 and data processing unit 4 side, and
I was able to receive one call.

Problems to be Solved by the Invention> However, in the conventional data communication terminal 1 having such a configuration, it is troublesome to switch the switch 2 to automatically receive a call when a person leaves. Many people forget to switch the switch, and if they forget to switch it, for example, when collecting sales data from a center etc. at night via data communication, the data cannot be collected, causing a serious inconvenience. Ta.

In addition, even if there are people in a store, etc., for example, data communication from a center etc. occurs at approximately fixed times.

When there is an incoming call, if the switch 2 is connected to the telephone separately, a person must answer the telephone at a distance of 1 m and switch to data communication, which is troublesome.

An object of the present invention is to provide a data communication terminal that solves these problems.

Means for Solving the Problems> In order to solve the problems described above, the data communication terminal of the present invention includes: a data communication terminal provided between the telephone line terminal and the switching device; An incoming call detection circuit that detects an incoming call and outputs an incoming call detection signal, a clock circuit that outputs a time signal, a time zone memory circuit that stores a data communication time zone, and a setting that sets a time zone in the time zone memory circuit. means; a time zone determination circuit that determines whether or not a time signal from the clock circuit when receiving the incoming call detection signal from the incoming call detection circuit is within a time zone set in the time zone storage circuit; and a switching control device that switches the switch to the data processing unit side when the incoming time is within the time slot based on a judgment signal from the time slot judgment circuit.

With this configuration, if the time zone for data communication is set in the time zone memory circuit in advance, the switching device can
If there is an incoming call for data communication during that time period, the incoming call detection circuit detects this and outputs an incoming call detection signal, and the time zone determination circuit detects the incoming call detection signal when receiving this signal. It is determined whether the time received from the clock circuit is within the time zone set in the time zone storage circuit, and if it is within the time zone, the switch is automatically switched to the data processing unit side by the switch 611 device. The data communication is then performed.

In addition, when a call arrives for data communication within this time period, the switch is automatically switched to the data processing unit side, and then
The time zone can also be rewritten by sending data for rewriting the time zone set in the time zone storage circuit.

<Example of the present invention> The present invention will now be described in detail as shown in the drawings.

FIG. 1 shows an embodiment of the invention.

In the figure, L1 and L2 are telephone line terminals, 1 is a telephone, and 10 is a data communication terminal provided between the telephone line terminals L1 and L2 and a separate telephone.

11 is transformation iil! It is a device. 12 is always on the phone!
This switch is connected to the telephone line terminal L1, L2 side and switches the connection with the telephone line terminals L1, L2 to the modulation/demodulation Hffff12 side using a manual switch or a switching control device 19 described later.

Reference numeral 13 denotes an incoming call detection circuit that detects incoming calls to the telephone line terminal and outputs an incoming call detection signal.

14 is a clock circuit that outputs a time signal.

Reference numeral 15 denotes a time zone storage circuit that stores a data communication time zone (for example, a scheduled time zone for receiving data from a center, etc.).

Reference numeral 16 denotes a time zone setting means (for example, a keyboard, etc.) for setting a time zone in the time zone storage circuit 15.

Reference numeral 17 denotes a display device that displays data such as the time period set in the time period storage circuit 15 and the sales amount processed by the data processing device 20, which will be described later.

18 refers to the time signal from the clock circuit 14 when receiving the incoming call detection signal from the incoming call detection circuit 13 and the time zone set in the time zone storage circuit 15, and determines whether this time is the time. This is a time zone determination circuit that determines whether or not it is within the time zone set in the zone storage circuit 15.

19 is determined by the determination signal from the time zone determination circuit,
If the arrival time is within the data communication time zone, the switch 12 is set to the modem r! Switching to switch to 111 side 11-111
1 device.

20 processes data through data communication via the switching device 12 and the modulation/demodulation device @ 11, and at the end of the data communication, transfers the switching device to the switching device 1IIII device 19.
This is a data processing device that outputs an end signal for returning the data to the storage side.

Next, the operation of the data communication terminal (F terminal 10) shown in FIG.
This will be explained by taking data communication between a store, etc. and a center, etc. as an example.

First, the store side and the center side agree on a regular reception time slot from the center, etc., and this regular reception time slot is set in the time slot storage circuit 15 by the time slot setting means 16. This can be set for one time zone or multiple time zones. The set time period is displayed on the display device 17.

When there is an incoming call from the outside to the telephone line terminals [1, L2, the incoming call detection circuit 13 detects this and outputs an incoming call detection signal to the time zone determination circuit 18. When the time zone determination circuit 18 receives this incoming call detection signal, the time zone determination circuit 18 transmits a signal to the switch m device 19 to determine whether or not the time signal from the clock 114 at this time is within the time zone set in the time zone memory circuit 15. Output to.

If it is not within the time period, the switching ff1Jl device 19 does not output a switching signal, and the switching device 12 remains connected to the telephone SI side.

If it is within the time period, the switching sub-unit device 19 switches the switch 12 to the modem @11 side using the switching signal.

Therefore, even if there are no people in the store at night, if there is an incoming call for data communication from the center etc. during this preset time period, the phone line will be automatically switched to the data communication side and the telephone line terminals L1 and L2 will be switched to the data communication side. is connected to the modulation/demodulation device 11, performs data communication with the data processing device 20, and collects and receives sales data. Therefore, data communication can be performed without manually switching the switch 12 to the modem 11 side each time a person leaves the store.

Additionally, if the center wants to change the time zone for future data communications, it sends data for changing the time zone at this time and rewrites the time zone stored in the time zone storage circuit 15 in the data processing bag M20. You can also do it.

When the data communication is completed, the data processing bag @20 sends a termination signal to the switching device 61 device 19, and the switching device a device 19 returns the switching device 12 to the telephone II side.

Furthermore, if someone is present at a store etc. and there is an incoming call for data communication, the switch 12 is manually switched for data communication after the person answers at the telephone tll, but within the set time period. In this case, the communication is automatically switched to data communication without having to answer each telephone device.

In addition, in FIG. 2, the clock circuit 14, time zone determination circuit 18, and data processing device 20 in FIG.
An embodiment is shown in which the device I'19 is constituted by a relay A, and the switch 12 is constituted by a contact a of the relay A.

A program for the operation of the CPU 30 is stored in the ROM 33, and the processing procedure of the CPLJ 30 is executed as shown in FIG.

Effects of the Present Invention Since the present invention is configured as described above, when receiving an incoming data communication call while the user is away, there is no inconvenience caused by forgetting to switch to automatic incoming call. Furthermore, if it is during the set time period, there is no need for a person to answer the call on the telephone and switch to data communication.
