摘要：
Disclosed is an image data transmission apparatus such as facsimile apparatus, in which a unit quantity of image data is encoded in variable length and transmitted into a transmission line, when the encoded unit quantity of the image data is less than a predetermined value, false data is added to the encoded unit quantity of the image data so that the transmission time of the unit quantity of the image data may be a first minimum time, and when no image data has been transmitted for a predetermined period on the condition of the transmission line being connected, then the transmission line is off. This improvement comprises:
a transmission apparatus main body, and
an image reading unit detachably mounted on the transmission apparatus main body;
the transmission apparatus main body comprising:
a memory for storing the read image data in each unit quantity, and
means for transmitting the image data in the unit quantity, and when the image data quantity to be transmitted stored in the memory is less than a predetermined data quantity, false data is added to the unit quantity so that the transmission time of the unit quantity may be a second minimum time exceeding the first minimum time.
