The reinforcement member is located below the mounting member. The positioning pin includes an upper part having a guard part and a lower part. The pin penetrates the mounting member so that the upper part can fit in the positioning depression and the lower part can come into contact with the reinforcement member. When the apparatus main body is placed, the upper part fits in the positioning depression, the guard part comes into contact with an edge of the positioning depression and the lower part comes into contact with the reinforcement member.</p> |
