PURPOSE: An operation recorder is provided to prevent a case that a holder cannot be moved relatively for a guide frame due to the movement of an intermediate frame generated by the damage of the support relation of the holder for the intermediate frame. CONSTITUTION: When a holder is assembled for an internal frame, a stopper fragment(44r) is formed by extending a notch(44e) installed in a front fragment(44a) of an internal frame(42') to easily insert a guide pin of a holder into a guide slot(44d) of the front fragment(44a) of an internal frame. Accordingly, if the stopper fragment(44r) is configured by extending the notch(44e) installed the front fragment(44a) of the internal frame(42'), an additional configuration to install the stopper fragment(44r) newly is not necessary by using the old front fragment(44a) effectively. |
