Title:
通信装置
Document Type and Number:
Japanese Patent JP5201213
Kind Code:
B2
Abstract:
A communicating unit used in an X-ray image pickup apparatus in this invention has an error detecting function to detect communication errors, and an FIFO for temporarily storing data received from a control and image processing apparatus, which is an external apparatus, by a receiving function of a communication control unit. Only when no error is detected within a predetermined period before and after receipt of data, by the receiving function of the communication control unit, from the control and image processing apparatus, a transmitting function of the communication control unit performs controls to transmit and write the data received and temporarily stored in the FIFO to/in an external portion. Thus, when a cable is plugged or unplugged or the control and image processing apparatus which is an external apparatus is rebooted, the error detecting function detects this as a communication error. In such cases also, an inadvertent writing of the data can be prevented. Therefore, a writing operation can be carried out also when there is no communication error. As a result, even if a communication error occurs, an inadvertent writing of data is prevented, and working efficiency is improved.
