Image reading apparatus

An image reading apparatus, attached to and as freely removable from an information processing device, for reading an image on a read medium, comprising:

• a read control device controlling a read of an image;
• a notification device notifying the information processing device of a change in display direction of a part or all of the image displayed on the display device depending on a state of the read of the image controlled by said read control device;
• and
• a function block control device performing power supply control or operation clock distribution control on each function block, wherein
• said function block control device is configured to perform the power supply control or the operation clock distribution control on each function block depending on a state of the read of an image controlled by said read control device.
