ABSTRACT:
A locking/unlocking mechanism for an operable cover of a body such as a printer to lock and unlock the body with a single operation and to a printer having an operable cover and a locking/unlocking mechanism for the operable cover. The operable cover is locked when a cover side engaging part in the cover engages a body-side engaging part in the body. The printer has a cover opening button10which is depressed to a first operating position10B, causing a locking lever14in the locking/unlocking mechanism11to slide from a locked position14A to an unlocked position14B. The locking lever has an engaging channel15which releases the cover-side engaging part12of the operable cover4, thereby disengaging the operable cover4but not opening it. When the cover opening button10is further depressed to a second (final) operating position10C, the locking lever14swings vertically pivoting on a guide pin24, which causes a cover-lifting surface16of the locking lever14to push the cover-side engaging part12of the operable cover4upward which opens the operable cover4. The operable cover4is thus both unlocked and opened by simply pressing the cover opening button10.
