Image reading device and image forming apparatus

1. An image reading device comprising:

a document pressing portion that is attached to an apparatus body and is configured to open or close to the apparatus body to press a document in between;

a restoring force applying portion that is compressed and deformed to apply an elastic restoring force to the document pressing portion in an opening direction of the document pressing portion; and

a releasing portion that releases compressive deformation of the restoring force applying portion by being grasped when the document pressing portion opens, the releasing portion comprising a compression and deformation portion configured to compress and deform the restoring force applying portion after the document pressing portion is opened.

2. The image reading device according to claim 1 ,

wherein the releasing portion comprises a holding portion that is grasped to release the compressive deformation of the restoring force applying portion when the document pressing portion is opened.

3. The image reading device according to claim 2 , further comprising

an energization member configured to energize the releasing portion normally so as to compress and deform the restoring force applying portion and to hold a compressed and deformed state of the restoring force applying portion.

4. The image reading device according to claim 3 ,

wherein the releasing portion is configured to compress and deform the restoring force applying portion when the releasing portion is released.

5. The image reading device according to claim 1 ,

wherein the compression and deformation portion comprises a latch portion that is attached in a state of being bent toward the restoring force applying portion, and that is configured to hold the restoring force applying portion in a compressed and deformed state after the restoring force applying portion opens the document pressing portion.
