1. A reading device connected to an external device, the reading device comprising:
a transport section configured to transport a document;
a reading section configured to read the document transported by the transport section;
a data generation section configured to generate image data of the document read by the reading section;
a transfer section configured to transfer the image data to the external device;
a notification section configured to notify information to a user; and
a control section, wherein
the control section is configured to
control a transport speed of the document by the transport section based on a transfer speed of the image data by the transfer section and
when the transport speed is changed, cause the notification section to notify using a change notification indicating a change in the transport speed, wherein
when the transfer speed is less than an improvement threshold value, the control section causes the notification section to notify using an improvement notification prompting improvement of the transfer speed, and
when the transfer speed is less than an error threshold value, which is smaller than the improvement threshold value, the control section stops the transport section and causes the notification section to notify of an error.
 
10. A reading device connected to an external device, the reading device comprising:
a transport section configured to transport a document;
a reading section configured to read the document transported by the transport section;
a data generation section configured to generate image data of the document read by the reading section;
a transfer section configured to transfer the image data to the external device;
a notification section configured to notify information to a user; and
a control section, wherein
the control section is configured to
control a transport speed of the document by the transport section based on a transfer speed of the image data transferred by the transfer section and
when the transfer speed is less than an improvement threshold value, cause the notification section to issue an improvement notification for prompting improvement of the transfer speed,
wherein when the transfer speed is less than an error threshold value, which is smaller than the improvement threshold value, the control section stops the transport section and causes the notification section to notify of an error.
 
11. A method for controlling a reading device that, by reading a document that was transported, generates image data of the document, the method comprising:
changing a transport speed of the document based on a transfer speed of the image data transferred from the reading device to an external device; and
notifying about a change in the transport speed when changing the transport speed, wherein when the transfer speed is less than an improvement threshold value, an improvement notification is used to notify prompting improvement of the transfer speed, and when the transfer speed is less than an error threshold value, which is smaller than the improvement threshold value, the control section stops the transport section and causes the notification section to notify of an error.
