Description

The present invention relates to a facsimile apparatus having a polling function. (B) Conventional technology In a facsimile apparatus, if a document is set on a transmitting side and a polling mode is set, a document set on a polling request from a receiving side can be automatically transmitted. Although a polling function is provided, the number of documents that can be set on the sending side is for one receiving station.
When the polling transmission is completed, the document is ejected, so that it was impossible to respond to polling requests from a plurality of receiving stations. To solve this problem recently, for example,
As disclosed in JP-A-155672, a memory for storing read original data is provided, and in response to a polling request from a plurality of receiving stations, the original data is read from the memory and transmitted each time, thereby polling a plurality of receiving stations. A facsimile apparatus having a memory polling function capable of transmitting has been developed. This makes it possible to respond to polling requests from a plurality of receiving stations. However, in this case, if one operator sets polling and the original data is stored in the memory, another operator cannot set the polling setting. Had occurred. (C) Problems to be solved by the invention The present invention has been made to solve the above problems.
An object of the present invention is to provide a facsimile apparatus in which a plurality of operators can perform memory polling setting. (D) Means for Solving the Problems The present invention provides a document memory for storing read document data, a block memory for dividing stored documents for each operator, and a block memory for storing a state of each block, and a document memory for each document. A block number, a start address indicating the storage start position of the document memory, and a password are stored, a directory memory for identifying which receiving station is the document data, and a polling request sent from the receiving station when a polling request is issued. Detects the identification code (ID code), compares it with the password stored in the directory memory, reads the start address data stored together with the matched password, reads and sends the original data from the original memory based on the address data This is configured by control means for performing control. (E) Operation Since the present invention is configured as described above, when there is a polling request from the receiving station, the control means searches the directory memory storing the password and the address data corresponding to each document, and detects the detected password. If the password is set differently by reading and transmitting the original data from the original memory based on the address data corresponding to the password, a plurality of operators can set the polling. (F) Example Hereinafter, an example of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a facsimile apparatus according to the present invention, wherein (1) is a control circuit for controlling the entire facsimile apparatus, which is constituted by a microprocessor;
Each part is controlled in accordance with a program in a program memory (2) in which a processing program is stored. The control circuit (1) also performs signal processing of the read transmission original data and processing of the received signal. (3) a reading unit that optically reads a transmission original, converts the read black-and-white data into an electric signal, and supplies the electric signal to the control circuit (1); Have been. A recording unit (4) drives a recording head such as a thermal head under the control of the control circuit (1) based on the received signal to perform printing, and is composed of a recording paper and a recording paper transport mechanism and a recording head. . (5) is the transmission key,
A control circuit (1) that is a keyboard composed of a reception key, a mode key, and a numeric keypad and that captures key signals.
Controls according to the program in the program memory (2) according to the key signal. (6) is a display for displaying data and the like input from the keyboard (5). Reference numeral (7) denotes a document memory in which data read by the reading section (3) is encoded and stored by the control circuit (1), and writing and reading of data are controlled by the control circuit (1). As shown in FIG. 2, original data read and written are sequentially stored in the original memory (7), and are managed by block numbers. (8) is a block memory for storing the state of the block. As shown in FIG. 3, five blocks from "0" to "4" are currently set. 1 "is written. (9) is a directory memory in which management data for each read original is stored. As shown in FIG. 4, a block number, password, transmission mode data and original memory (7) are written for one original. Start address data to be stored is stored. (10) is an ID code buffer for storing the ID code transmitted from the receiving side. (11) A modem circuit comprising a modulation circuit that receives encoded transmission data and modulates it into a signal that can be transmitted to the telephone line (L), and a demodulation circuit that demodulates the received signal.
(12) is a network control circuit for switching between the modem circuit (11) and the telephone (13) and connecting to the telephone line (L), and is constituted by a relay circuit or the like. The network control circuit (12) has a built-in incoming call detection circuit that outputs an incoming call detection signal to the control circuit (1) upon detection of an incoming bell signal. Next, the operation of the present invention having such a configuration will be described. First, in normal transmission, after setting the original in the reading section (3), the telephone (13) calls the facsimile apparatus on the receiving side, and after confirming that the receiving side is compatible, the transmission key of the keyboard (5) is operated. Then, the control circuit (1) that has detected the transmission key signal controls the reading section (3), encodes the read document data, and performs transmission. On the other hand, in the standby state, the control circuit (1) which has detected the incoming call performs a decoding process on the received signal and performs recording processing (4).
And record the received data by printing. Next, a memory polling operation which is a feature of the present invention will be described. The operator on the transmitting side, which has previously discussed polling transmission with the receiving side on the telephone (13), sets the memory polling mode by operating the keyboard (5) at step (501) in FIG. The control circuit (1) which has detected the key signal searches the block memory (8) at step (502) to detect whether or not there is an empty block. If all the blocks are in use, the flow advances to step (504) to display on the display (6) that memory polling cannot be set, inform the operator, and return to the standby state. On the other hand, if there is an empty block, the block number first detected in step (505) is temporarily stored in a buffer memory in the control circuit (1), and the block number is displayed on the display (6) to be used by the operator. And prompts the operator to input a password, and instructs the operator to input the password. Then, in step (506), when the operator inputs the same number as the ID code of the receiving station from the keyboard (5),
Next, the control circuit (1) writes data "1" in the flag area corresponding to the block number to be used in the block memory (8) in step (507), sets the block in use, and then proceeds to step (508). ), The block number and the password are written in the area corresponding to the first document A in the directory memory (9). Assuming that the block number to be used is "0" and the password is "1234", data is written to the block memory (8) and the directory memory (9) as shown in FIG. Then, in step (509), the paper size, sub-scanning speed,
Check the transmission mode, such as shading, and write it to the directory memory. In the case of the first document, the first address data "0000" of the document memory (7) is written in the start address area. Next, the process proceeds to step (510) to control the reading section (3) to read the original data, perform an encoding process, and write it to the original memory (7). When reading of the first document A is completed, the control circuit (1) checks the address of the document memory (7) where the last data of the first document data is written in step (511). The address "aaaa" at which the next document data is to be written is obtained, and is written to the start address area of the directory memory (9) where data relating to the next document is stored as shown in FIG. 9 (c).
Then, the process proceeds to step (512) to check whether or not there is a document. If there is no document, the process returns to the standby state. However, if there is a document, the process returns from step (512) to step (508). Is performed. The block number and the password are the same for the second original B. The block number and the password stored in the buffer memory in the control circuit (1) are read out, and the directory memory (9) is read as shown in FIG. ).
In this way, the reading of the second document B is completed, and the control circuit (1) which has detected in step (512) that there is no next document returns to the standby state. As a result, as shown in FIG. 9, the block with the block number "0" is used, the data relating to the two originals A and B are stored in the directory memory (9), and the two originals are stored in the original memory (7). Document data is stored. Next, when another operator sets memory polling, the same processing as described above can be performed.
In this case, the block number "1" is used, and the data is stored in the block memory (8) and the directory memory (9) as shown in FIG. 10 by inputting the password. Then, in step (510), the data is written in the original memory (7) where the original data is read.
The control circuit (1) reads the start address "bbbb" in the area corresponding to the third document C in the directory memory (9) and writes data in the document memory (7). Is written after the previously stored original data. When there is only one document, data writing is performed as shown in FIG. If a polling request is sent unconditionally, a password entry is omitted and stored. In this way, a plurality of operators can set the memory polling. Since the block numbers are now set from "0" to "4", it is possible to set the memory polling for up to five operators. Next, the operation of performing polling transmission when there is a polling request from the receiving station in the state where the memory polling is set will be described with reference to FIG. In the standby state, the control circuit (1) checks in step (601) whether or not there is an incoming call, there is an incoming call due to a polling request from the receiving station, and the incoming call is detected by the incoming call detection circuit of the network control circuit (12). The detected control circuit (1)
Proceed to step (602) to connect the telephone line (L) to the telephone (13)
To the modem circuit (11). Next, in step (603), it is determined whether or not the received request is a polling request. If the request is not a polling request, the process proceeds to a normal reception processing routine (604). , The ID code of the receiving station is detected and stored in the ID code buffer (10). If the ID code is a polling request from the receiving station having the ID code "1234", the ID code "1234" is stored in the ID code buffer (10). Subsequently, the control circuit (1) proceeds to step (606), searches the directory memory (9), and determines whether or not there is a polling document in step (607). If no polling document is stored, the control circuit (1) proceeds to step (606). At 612), the line is disconnected to return to the standby state. However, since the manuscript data is now stored, the process proceeds to step (608) to determine whether or not a password has been set. If so, the process proceeds to step (609) and the directory memory (9)
Is compared with the ID code of the ID code buffer (10), and if they match, the process proceeds to step (610) to read the start address data from the start address area, and the original data is read from the original memory (7) based on the read address data. Is read out, and based on the transmission mode data stored in the transmission mode area of the directory memory (9), predetermined transmission processing is performed in step (611), and the data is transmitted via the modem circuit (11) and the network control circuit (12). Transmit to the telephone line (L) and transmit to the receiving station. When reading of one document data is completed in this way, the process returns to step (606) to search the directory memory (9) and
The area corresponding to the first document is checked. Since the password stored here also matches, the document memory (7)
Then, the second original data is read and transmitted. When the transmission of the second copy is completed, the directory memory (9) is similarly set.
Search is performed on the third document, but since the password of the third document is different, reading from the document memory (7) is not performed, and step (60) is performed.
Returning from step 9) to step (606), a check is performed on the fourth document in the directory memory (9). Now 4
Since the document data of the first sheet is not stored, the process proceeds from step (607) to step (612) to disconnect the line and return to the standby state. When a polling request is received from the receiving station having the ID code "5678" for the third original C, the third original data is read from the original memory (7) in the same manner as described above by matching the passwords. And sent. If there is a document that has been stored without a password, when the absence of a password is detected in step (608), the process proceeds to step (610) and transmission is performed. Sent to the condition. Thus, as shown in FIG. 11, the originals A and B stored with the password "1234" are transmitted to the receiving station "I @" with the ID code "1234" and stored with the password "5678". The original C is transmitted to the receiving station "II", and the originals D, E, and F stored without a password are transmitted to all the receiving stations that have requested the polling, so that the receiving stations "I", "II" ”And a different ID code from the receiving station“ III ”. Next, after the polling transmission is completed, the unnecessary document data is deleted by setting the deletion mode using the keyboard (5) at step (701) as shown in FIG. 7, and then using the block number used at step (702). In step (703), data "0" is written in the flag area corresponding to the block number of the block memory (8) to make it empty, and then in step (704), the directory memory (9) is entered. To search for an area in which the same block number as the input block number is stored, read out the address data stored in correspondence with the area, and read the original memory (7) in step (707). Is erased. In this manner, all originals having the same block number are erased. (G) Effect of the Invention As described above, the facsimile apparatus of the present invention is configured to store the original data together with the password at the time of setting the memory polling and to transmit the original data with the same password. By setting, a plurality of operators can set the memory polling, and the use efficiency of the facsimile apparatus is improved. Also, when comparing the ID code sent from the receiving station with the password, only access to the storage means storing the storage position information of each document data in the memory and the password corresponding to each of the above document data is paired. And the amount of data in the storage means is much smaller than that of the memory in which the original data is stored, so that it is necessary to read the password for the ratio processing and to read the original data to be polled and transmitted. As a result, the time required for the polling transmission from the incoming call to the end of the transmission of the document data can be shortened as much as possible.
