Abstract:
1. A sheet size setting device for giving information for identifying a sheet size to a sheet size detector, the sheet size setting device comprising: a housing including a first mounting section having a first space, and a second mounting section adjacent to the first mounting section and having a second space; a first rotary member having a cylindrical shape, and supported on the first mounting section, and rotatable around and slidably movable along a first axis extending to the second space in the first space an engaging portion provided in the housing; a biasing member; a second rotary member supported on the second mounting section rotatably around a second axis parallel to the first axis; and an assisting mechanism, wherein the first rotary member includes a first region, a second region, and a third region along the first axis, the first rotary member further including: wherein the housing includes: wherein the engaging portion is disposed on the second supporting plate in such a way as to face one of the plurality of engaged portions, the engaging portion being operable to engage with the one of the plurality of engaged portions in the rotation of the first rotary member around the first axis to thereby restrict the rotation of the first rotary member, wherein the biasing member is disposed between the first supporting plate and the first rotary member for biasing the first rotary member in a direction of permitting the one of the plurality of engaged portions to engage with the engaging portion, wherein the second rotary member includes: wherein the second rotary member is rotated in a specific direction around the second axis to rotate the first rotary member to set a sheet size, and wherein the assisting mechanism applies a moving force to the first rotary member in the axial direction with the rotation of the second rotary member around the second axis so that the one of the plurality of engaged portions disengages from the engaging portion against the biasing force of the biasing member.
