Abstract
A sheet size detection device for detecting a size of sheets which are held in a cassette body comprises a first guide member for defining the position of the sheets which are held in the body of the cassette, in a first direction of the sheets, the first guide member being movable in accordance with the size of sheets, a second guide member for defining the position of the sheets, in a second direction of the sheets, the second direction being orthogonal to the first direction, the second guide member being movable in accordance with the size of sheets, a first arm having a first resistor and movable with the first guide member, a second arm having a second resistor and movable with the second guide member, the first and second resistors constituting a variable resistor, and a size detector for detecting the size of the sheets on the basis of the resistance value of the variable resistor.
