Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transmission device, and more particularly to a transmission device having a single transmitting/receiving display unit that displays various data during transmission and reception.

This type of transmission device is a device that transmits desired image information between places that are separated from each other. Image information to be transmitted, such as a blueprint, is read by a reading unit on the transmitting side, and the recording unit on the receiving side reads the image information to be transmitted, such as a blueprint. The image information is reproduced and recorded. Such conventional transmission devices, especially devices capable of automatic reception, have an operation section for transmission and an operation section for reception.
The number of parts in the operating section increased, and the operation was complicated.

Therefore, in order to eliminate such drawbacks, it is conceivable to provide an operation section for both transmission and reception, and to switch the operation section to reception when receiving, and to switch to transmission when not receiving.

However, if you switch the operation section to receive when receiving, and switch the operation section to send when not receiving, then when you are operating the operation section to enter the destination etc. of the image to be sent when sending, When a message is received, the reception will start even if the destination is being input, and the operation section will automatically switch to reception. Therefore, there is a risk that the data related to transmission, such as the destination, which was being inputted, will be volatile, and the data related to transmission that has been inputted will be wasted.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a transmitting/receiving means for transmitting or receiving an image, an operating means for setting data related to transmission such as a destination of the transmitted image, and a transmitting/receiving means for transmitting or receiving an image. control means for controlling the transmission of images according to the data regarding the operation, detecting the presence or absence of image reception, and controlling the reception of the images according to the detection; and holding data regarding the transmission set by the operation means. holding means, when an image is received while the operation means is setting data related to the transmission, the holding means holds the data being set and receives the image, and after the image reception is completed, the holding means The configuration is such that image transmission is possible according to the data related to the transmission held in the means. As a result, when sending an image, if an image is received while inputting data related to sending such as the destination, the data related to the sending that is being input is retained, and after the reception is completed, the saved data related to sending can be used to send the image. The objective is to provide a transmission device that is

FIG. 8 shows an example of the operation display section, where 9
0 is a lamp that lights up while transmitting, 91 is a lamp that lights up while receiving, 92 is a counter that displays the number of copies, 93 is a numeric keypad, 94 is a clear key, 95 is a key to start copying or sending, and 96 is a key to start copying or sending. The stop keys 97A to 97J are destination keys for temporarily stopping the transmission operation. One destination is assigned to each key in advance, and when transmitting, the key of the desired destination is pressed down. In this example, the key 97J is assigned a local copy function, that is, a function that performs a recording operation in its own recording unit. When you press these keys 97A to 97J, the REQ
Lamp 98A lights up. Further, during automatic reception, the REQ lamp 98A corresponding to the destination is displayed, allowing the destination to be known. 98B is an error display lamp, 99A is a lamp that indicates the occurrence of a jam, 99B is a lamp that indicates an error during transmission, and 99C is a lamp that indicates an error during reception.

Now, let us take as an example a case where image information is transmitted from another second copying and transmitting device to the first copying and transmitting device during a transmission operation on the first copying and transmitting device on the sending side.
The operating procedure will be explained with reference to the figures.

When the power is turned on, RAM and I/O are initialized in step S1. Next, if image information is not received in step S2, steps S3, S4, S5, S
The process proceeds to step S7 via step S6. Here, when a desired destination key, for example, key 97A, is pressed, the sending address is set in step S8, and the REQ lamp 98A under key 97A lights up in step S9, indicating where the image information is being sent. I understand.

Here, when image information is transmitted from the second copying and transmitting apparatus after sequentially executing steps S2 to S9 and selecting a destination, an affirmative determination is made in step S2 and the process proceeds to step S19. In step S19, the printer of the first copying and transmitting device is checked, and in step S20, it is determined whether the printer status is an error. If there is an error, the reception error lamp 99C is turned on in step S26. Further, when it is determined that there is no error in step S20, the receiving lamp 91 is turned on in step S21, and the receiving lamp 91 is turned on in step S22.
Then, the data set for transmission and display data are temporarily saved in the memory 52A. Next, in step S23, it is determined whether there is a reception error, and if there is a reception error, the reception error lamp 99C is turned on in step S26. If there is no reception error, the process advances to step S24 to execute the reception sequence, and when it is determined in step S25 that the reception has ended, the series of reception sequences ends. If an affirmative determination is made in step S25, step S
At step 27, the receiving LED is turned off and the process returns to step S2.

Next, when the start key 95 is pressed to transmit the desired image in the previously set transmission mode, an affirmative determination is made in step S5, and the process proceeds to step S10. Since the transmission mode is now selected, the transmitting LED is turned on in step S10A, and then the data saved in the memory 52A is read out as necessary. Next, the process advances to step S11 to check the status of the destination. If the destination is in an error state in step S12,
For example, if local copying is in progress, in step S15,
Turn on the ERR lamp 98B under the key 97A and proceed to step S2. Furthermore, if it is determined to be normal in step S12, a transmission sequence is executed in step S13, and if it is determined that transmission has been completed in step S14, the transmitting LED is turned off in step S14A, and the series of transmission procedures is completed. .

On the other hand, when executing a local copy, the process advances from step S10 to step S16, and after checking the status of its own printer, a copy sequence is executed in step S17, and when it is determined that the copy has been completed in step S18, a series of copies is executed. The procedure ends. In addition,
In this example, as described above, local copy is selected by pressing the key 97J.

As described above, according to the present invention, when transmitting an image, if an image is received while inputting data related to the transmission such as a destination, the data related to the transmission being input is held, and after the reception is completed, the data related to the transmission held is The configuration is such that it is possible to transmit images using data. This reduces the number of parts in the operation section and simplifies its configuration, and even if a reception occurs while inputting transmission-related data such as a destination, the entered transmission-related data can be used for transmission without being lost. .
