Abstract:
1. An image generating apparatus comprising: a chassis including a first mounting portion and a second mounting portion; and a print head including a plate-like first arm and a plate-like second arm rotatably mounted on said first mounting portion and said second mounting portion of said chassis respectively, wherein said first arm and said second arm of said print head are integrally provided with an L-shaped first stop portion and an L-shaped second stop portion regulating movement of said print head in the direction of a rotation axis respectively, a first angular range in which said first arm of said print head is mountable on/dismountable from said first mounting portion of said chassis limited by said first stop portion is different from a second angular range in which said second arm of said print head is mountable on/dismountable from said second mounting portion of said chassis limited by said second stop portion, said first arm and said second arm of said print head are mounted on said first mounting portion and said second mounting portion of said chassis in said first angular range and said second angular range respectively and said print head is thereafter so rotated that said print head is stopped by said first stop portion and said second stop portion in the direction of said rotation axis, said first arm is mounted on said first mounting portion such that said first mounting portion is sandwiched between said first arm and said first stop portion, said second arm is mounted on said second mounting portion such that said second mounting portion is sandwiched between said second arm and said second stop portion, said first mounting portion of said chassis is provided with a first notch relieving said first stop portion when said first arm is mounted on said first mounting portion, said second mounting portion of said chassis is provided with a second notch relieving said second stop portion when said second arm is mounted on said second mounting portion, and said first notch and said second notch are so formed as to have different notch angles, so that said first angular range and said second angular range are different from each other.
