Description

[Detailed description of the invention]

INDUSTRIAL APPLICATION FIELD The present invention relates to a storage and broadcasting device for specifying destinations using an OMR sheet or a push-button telephone. Conventional facsimile IJ devices use an OMR sheet or a built-in push-button telephone to specify the destination of a document. OMR
A sheet is a sheet with black marks representing designated items such as sender, destination, transmission time, etc., and is read by an optical mark reader (Optical Mark Reader).
) to recognize instructions. When using a push-button telephone, instructions such as the destination are given using push-button telephone signals (DTMF signals) representing 1 to 9, *, and #. DT from the OMR sheet information sent from the facsimile of the connected terminal or from the push-button telephone.
A storage/broadcasting device that recognizes an MF signal, stores the transmitted message, and transmits it to a designated destination at a designated time is capable of recognizing both of these signals. FIG. 9 is a diagram showing an example of such a storage and broadcasting device. In the figure, a communication control section 1 is provided for each line, and this communication control section 1 is provided with either a DTMF detection circuit 13 or an OMR recognition circuit 15. Each communication control unit 1
is connected to a control unit 2 via an interface 4, and the control unit 2 controls the storage of messages input and output from each line into the memory 3. Problems to be Solved by the Invention However, according to this configuration, input from a Bunsch button type telephone can only be handled by the communication control unit 1 equipped with the DTMF detection circuit 13, and OMR sheet input can only be handled by the communication control unit 1 equipped with the OMR recognition circuit 15. It can only be handled by the communication control unit 1. For this reason, the destination designation method is fixed for each line, and it is not possible to create a network of lines using the representative telephone system. The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a storage/broadcasting device that can handle any line into which a DTMF signal or OMR sheet signal is input. Means for Solving the Problems In order to achieve the above object, each communication control unit is provided with a DTMF detection circuit and an OMR recognition circuit.

Further, a CNG detection circuit for detecting an automatic call signal from a facsimile terminal connected to the line is provided in parallel with the DTMF detection circuit. Effect: With the above configuration, the communication control unit connected to each line receives DTMF signals from a push-button telephone. Since it is possible to handle any input OMR sheet signal, there are no restrictions on the line. Also CN
By providing the G detection circuit in parallel with the DTMF circuit,
It becomes possible to immediately identify whether it is an automatic facsimile call or a DTMF signal. When an automatic facsimile call is recognized, the system automatically switches to the facsimile 1 facsimile procedure, making it possible to select a destination without waiting for the DTMF signal instruction waiting time. Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1st

A CPU 17 performs transmission and reception control using control software stored in the ROM 2S. A control interface circuit 19 controls the multipath interface 4. FIG. 3 is a diagram showing a DTMF signal, and (a) shows a broadcast destination instruction from a facsimile terminal to a storage/broadcast device. A # mark indicating a separation between the local station No. 123 representing the originating terminal station consisting of up to 7 digits and the next code, and a maximum of 7 digit code indicating the destination continue for the number of destinations, and end with the end code ##. (b) is a signal that performs a mailbox function to read out image data stored in the storage/broadcasting device from a facsimile terminal.Following the own station number, a service instruction *24# indicating an instruction to retrieve image data is inserted. . The storage/broadcast device recognizes this 24 code as a read instruction. Next is a PIN number that indicates the mailbox number. FIG. 4 is a flow diagram showing the operation of the communication control unit 1 to recognize a destination instruction. Generally, the destination is specified by using a push-button telephone signal, or by writing predetermined information on an OMR sheet and having it read. In this embodiment, a method will also be described in which destination information is recorded in advance on a facsimile terminal and specified using a one-touch key when transmitting. This flowchart is based on Recommendation T.30 of the CCITT (International Telegraph and Telephone Consultative Committee). First, the case of specifying a destination using a one-touch key will be explained with reference to FIG. In order to specify a destination using a one-touch key, destination information must be registered. This registration and one-touch key operation are performed according to the menu displayed on the display panel of the facsimile terminal. A message appears on the menu screen indicating that communication is possible, so select the registration menu.Press the function switch. (1) Home dial registration and (2) destination dial registration will appear as menu, so select (2). and automatically call N. and register the destination information. Then, when the set SW is set, registration to the one-touch key is completed. As a result, when you press the one-touch key when making a call, a call is made automatically, and the registered information is sent to the NSS signal (non-sequence for checking the status of the terminal, transmission path, etc. and controlling the terminal in the preprocessing process). Destination information is added to the standard function setting signal) and transmitted. In FIG. 4, after the communication control unit 1 automatically starts receiving a call, when it becomes ready to receive a DTMF signal instruction, it outputs a DTMF detection start signal (2400Hz).
step 40), D for 25 seconds)
When the TMF signal detection timer is started and a DTMF signal is detected (step 41), the receiver receives a destination instruction using the DTMF signal (step 42). identification signal) (step 44). Further, when the time period during which no DTMF signal is received reaches 25 seconds in step 41.43, the process moves to step 44. Step 44
After sending the CED signal, it is determined whether or not a DTMF instruction has been received (step 45). If no instruction has been received, the NS
The F destination instruction is set to be valid (step 46), and if the instruction was received in step 42, there is no need to issue a destination instruction again, so the NSF destination instruction is set to be invalid. Here, the NSF signal and the NSS signal which is a response signal to the NSF signal are non-standard function setting signals, and the contents can be determined by users. In this embodiment, the NSF signal indicates whether there is a destination instruction, and the NSS signal indicates the destination instruction. FIG. 6 shows step 4 from step 44 CED signal transmission to step 4.
8 represents communication up to phase B and original (phase C) transmission. The valid/invalid cent in step 46 and 47 is set in the facsimile information field of the NSF signal.If the destination instruction reception function is enabled, the bit is set to [1], and if the function is set, the bit is set to [1].

Define it to be set to [0]. Returning to FIG. 4, in step 49, it is checked whether or not the destination instruction has been completed using the DTMF signal or the N5F-NSS signal, and if it has been completed, the facsimile terminal starts receiving p (step 50). If the process has not been completed, detection of the OMR sheet input from the facsimile terminal is started, and the destination instruction is recognized (step 51). According to the above flow, the destination is automatically selected, the manuscript is accepted, and the broadcast and registration are performed. Next, a second embodiment will be explained using FIGS. 7 and 8. FIG. 7 is a block diagram showing the configuration of this embodiment, and the same reference numerals as in FIG. 1 represent members having the same functions. FIG. 7 shows a C
C to detect NG (Calling tone) signal
An NG detection circuit 20 is provided to distinguish between an automatic facsimile call and a DTMF signal. With this configuration, when waiting for the DTMF signal, the CNG detection circuit 20 is also operating, so the D
When the TMF signal is not detected, when a CNG signal is received, the process automatically switches to the facsimile procedure, and other destination instructions (instructions by NSS in phase B, instructions by OMR sheet) can be received. Since the CNG signal is transmitted at 3 second intervals when connected to the called station, the waiting time of 25 seconds at step 43 in the first embodiment shown in FIG. 4 is shortened to a maximum of 3 seconds. FIG. 8 shows a flowchart of this embodiment. The difference from the first embodiment shown in FIG. 4 is that step 43 in FIG.
The only difference is that G detection is used, and the rest is the same. Effects of the Invention As is clear from the above explanation, the present invention provides a DTMF detection circuit and an OMR recognition circuit in the communication control unit connected to each line, so that the destination designation method is not restricted by the line. DTMF signal or OM signal for line
Destination designation can be performed using the R sheet signal. By providing a CNG detection circuit in parallel with the DTMF detection circuit, it is possible to quickly determine whether the destination instruction is a DTMF signal or another destination instruction.
