Image reading apparatus having a blast mechanism

摘要

A blast mechanism in an image reading apparatus reliably cools heat generated in boards by a blast path with high cooling action among a plurality of boards disposed inside a casing. A partition plate is disposed between a plurality of boards disposed at a distance away in a layered shape, a first blast path is formed between a top of the casing and a first board, a second blast path is formed between the first board and the partition plate, a third blast path is formed between the partition plate and a second board, and a flow of cooling air is formed in each blast path with a blast fan. A blast mechanism for sending cooling air includes the casing, first and second boards disposed vertically inside the casing, the partition plate disposed between the first board and the second board, and fans for sending cooling air.

主权项

1. An image reading apparatus having a blast mechanism for sending cooling air to inside a casing of the image reading apparatus, the blast mechanism comprising:
first and second boards disposed in a vertical direction inside the casing, a partition plate disposed between the first board and the second board, and a blast fan for sending cooling air to the first and second boards, wherein a top of the casing, the first board, the partition plate and the second board are disposed in this order from above, while being spaced a distance apart, a first blast path is formed between the top and the first board, a second blast path is formed between the first board and the partition plate, a third blast path is formed between the partition plate and the second board, and the blast fan is disposed in a position overlapping each blast path when viewed from a direction intersecting the vertical direction.
