Abstract

PURPOSE:To surely and quickly send a picture data by storing a picture data to be sent in a recorder if a picture data transmitter-receiver at the receiver side is in transmission/reception of a picture data, reading the picture data from the recorder after the elapse of a set time and retransmitting the data. CONSTITUTION:Upon the receipt of a signal representing disabled transmission from a transmission/reception means 12, a transmission state discrimination means 13 control a picture data transfer means 15 such that a picture data to be sent is sent to a recorder 17 able to read/write and to be recorded therein and gives a start signal to a timer 16. Upon the receipt of a start signal from the transmission state discrimination means 13, the timer 16 sends a transmission request signal to a picture data transmission request input means 11 after the elapse of a set time or a time set by the user. A picture data transmission request input means 11 supplies a picture data read from the recorder 17 to a picture data input means 14, where the data is subject to processing.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an image data transmitting/receiving device, and more particularly to an image data transmitting/receiving device capable of quickly transmitting image data in accordance with the transmission/receiving conditions of a destination.

(Prior Art) When a conventional image data transmitting/receiving device receives a transmittable signal returned from the receiving side in response to sending a transmission request signal from the transmitting side, that is, when the receiving side device is receiving or If the transmission is in progress, the transmission side receives a signal from the reception side indicating that the reception side is in use (transmission disabled signal), notifies the user, and completes the process.

Therefore, a user who wishes to send image data must repeat the image data sending process until the image data sending/receiving device (on the recipient's side) becomes available.

(Problem to be Solved by the Invention) In the conventional image data transmitting/receiving device described above, when the receiving side is receiving or transmitting, that is, when transmission from the sending side is impossible, the user The process of transmitting the image data transmission request signal must be repeated until the image data transmitting/receiving device is ready to receive data, which not only complicates the information transmission by the image data transmitting/receiving device for the user, but also makes it difficult to quickly However, there is a problem in that it becomes difficult to transmit the image data.

(Means for Solving the Problems) In order to solve the above conventional problems, an image data transmitting/receiving device according to the present invention transmits an image data transmission request signal and the image data to a destination transmitting/receiving device, and transmits an image data transmission request signal and the image data to a destination transmitting/receiving device. a transmitting/receiving means for receiving a transmittable signal or a transmittable impossible signal from the device; and when the transmitting/receiving means receives the transmittable signal, transmitting the image data to the destination transmitting/receiving device via the transmitting/receiving means; control means for temporarily storing the image data in a storage circuit when the transmission impossible signal is received; and a control means for temporarily storing the image data in a storage circuit when the transmission impossible signal is received, the transmission request signal is sent through the transmitting/receiving means after a predetermined time; After receiving the transmittable signal, the image data is read from the storage circuit and sent to the destination transmitting/receiving device via the transmitting/receiving means.

(Example) Next, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram of an image data transmitting/receiving device showing an embodiment of the present invention.

An image data transmitting/receiving device 1 according to an embodiment of the present invention includes an image data transmission request input means 11, a transmission/reception function 12, a credit status determination means 13, an image data input means 14, an image data transfer means 15, a timer 16, reading/writing. It is made up of a recording device 17 that can be used.

Next, to explain the operation of this embodiment, when there is a request to transmit image data, this request is accepted by the image data transmission request input means 11, and is received by the image data transmitting and receiving device n1lJ via the transmitting and receiving means 12. sent to. The image data transmitting/receiving device on the receiving side returns a signal indicating whether or not it is capable of receiving data, that is, a signal indicating whether transmission is possible from the transmitting/receiving device 1. The transmitting/receiving means 12 receives a signal indicating whether transmission is possible from the transmitting/receiving means 1 from the image data transmitting/receiving device on the receiving side, and transmits the signal to the transmitting state determining means 13.
Send to. On the other hand, the image data input means 14 inputs image data to be transmitted in response to the transmission request from the image data transmission request input means 11, and inputs the image data to be transmitted to the image data transfer means 15.
supply to.

Now, when the transmission state determination means 13 receives a signal indicating that transmission is possible from the transmission and reception means 12, the image data transfer means 15
to transmit the image data via the transmitting/receiving means 12. When receiving a signal indicating that transmission is impossible, it controls the image data transfer means 15 to send and record the image data to be transmitted to the read/write recording device 17, and supplies a start signal to the timer 16. Like this,
When the image data transfer means 15 receives the transmission enable signal from the transmission state determination means 13, it transmits one image data to the image data transmission/reception device on the receiving side via the transmission/reception means 12. On the other hand, when receiving a signal indicating that transmission is impossible, the image data is supplied to the recording device 17 and stored therein.

After receiving the activation signal from the transmission state determining means 13, the timer 16 transmits a transmission request signal to the image data transmission request input means 1 after a predetermined time period, which is probably set by the user, has elapsed.
1, the 0 image data transmission request input means 11 sends the 0 image data to
If the image data transmitting/receiving device on the transmitting side is not in use, a transmission request signal is sent to the image data transmitting/receiving device on the receiving side via the transmitting/receiving means 12, and a recording device is sent to the image data inputting means 14! The image data read out from 17 is supplied to image data input means 14, from which the above-described image data processing is performed. =J, the image data transmission requesting means 11 restarts the timer 16 if the transmitting side image data transmitting/receiving device is being used. The operation after restarting is the same as described above.

(Effects of the Invention) As explained above, when the image data transmitting/receiving device according to the present invention transmits image data to another image data transmitting/receiving device, the image data transmitting/receiving device on the receiving side; If Mobiku is currently transmitting, it stores the image data to be transmitted in the recording device, reads the image data from the recording device after a predetermined time or a time specified by the user, and retransmits it, so it is up to the user to send the image data. There is no need for a retransmission procedure, and image data can be reliably and quickly transmitted just by performing the transmission procedure - times.
