Image Forming Device

An image forming device, comprising:

• a main body;
• a swing body attached to the main body swingably around a first axis as a predetermined swing central axis thereof between a first state where the swing body is away from the main body and a second state where the swing body is close to the main body;
• an arm having a first end and a second end in a longitudinal direction thereof, the first end of the arm being attached to a first one of the main body and the swing body, swingably around a second axis as a predetermined swing central axis of the arm;
• and
• a guide member provided to a second one of the main body and the swing body, the second end of the arm being joined with the guide member slidably in contact with the guide member from one end to a different end in the longitudinal direction of the guide member when the swing body swings from the first state to the second state,
• wherein the guide member includes a sliding contact surface configured to establish slidable contact with the second end of the arm, the sliding contact surface including first and second areas continuously formed in a longitudinal direction of the sliding contact surface, the second area being slanted relative to the first area.

An image forming device, comprising:

• a main body;
• a swing body attached to the main body swingably around a first axis as a predetermined swing central axis thereof between a first state in which the swing body is away from the main body and a second state in which the swing body is close to the main body;
• an arm having a first end and a second end in a longitudinal direction thereof, the first end of the arm being attached to a first one of the main body and the swing body, swingably around a second axis parallel to the first axis of the swing body as a predetermined swing central axis of the arm;
• a guide member provided to a second one of the main body and the swing body, the second end of the arm being joined with the guide member, slidably in contact with the guide member from one end to a different end in the longitudinal direction of the guide member when the swing body swings from the first state to the second state, the guide member including a sliding contact surface configured to establish slidable contact with the second end of the arm, the sliding contact surface including first and second areas continuously formed in a longitudinal direction of the sliding contact surface, the second area being slanted relative to the first area;
• and
• a pressing member provided to the second one of the main body and the swing body, the pressing member being configured to establish contact with the second end of the arm and press the arm toward the second axis of the arm in the second state,
• wherein the arm includes a contact surface that is provided to the second end of the arm and configured to contact the pressing member, the contact surface of the arm including a point of action that receives a pressing force from the pressing member, the contact surface of the arm being parallel to the second axis of the arm and slanted relative to a virtual plane perpendicular to an axial line of the arm that extends from the point of action toward the second axis of the arm.
