Image reading apparatus and image forming apparatus

An image reading apparatus, comprising:

• a document table on which a document is placed;
• a document reading unit which reads an image of a document;
• a document feed unit which has a document placement section on which a document subjected to a reading operation by the document reading unit is placed, the document feed unit being rotatable between a first posture for sandwiching the document between the document placement surface of the document table and the document feed unit by rotating the document feed unit to close the document feed unit, and a second posture rotated away from the document placement surface of the document table;
• a posture detection unit which detects whether the document feed unit is in the first posture or the second posture;
• a document presence/absence detection unit which detects whether or not a document has been placed on the document placement section of the document feed unit;
• an operating unit for inputting an instruction for the execution of a read operation by the document reading unit;
• and
• an operation control unit having a first control mode for controlling the operation of respective units including the document reading unit in order to read an image of a document placed on the document placement surface of the document table, and a second control mode for controlling the operation of respective units including the document reading unit in order to read an image of a document placed on the document placement section of the document feed unit,
• wherein the operation control unit sets as a current read object a document placed on the document placement surface of the document table when postures of the document feed unit are detected in the sequence of the second posture followed by the first posture by the posture detection unit, in a state where detection is made by the document presence/absence detection unit that a document is placed on the document placement section of the document feed unit, and when input of the execution instruction is accepted by the operating unit, the operation control unit controls the operation of the respective units including the document reading unit in the first control mode, and causes the document placed on the document placement section of the document feed unit to be output to a prescribed output position.

• and
• an input acceptance unit which accepts a selection input indicating whether or not to set a document placed on the document table as a read object document, when postures of the document feed unit have been detected in the sequence of the second posture followed by the first posture by the posture detection unit, in a state where detection is made by the document presence/absence detection unit that a document is placed on the document placement section of the document feed unit,
• wherein the operation control unit sets a document placed on the document table as a current read object, when the input acceptance unit accepts a selection input indicating that the document placed on the document table is to be set as a read object document.
