Abstract
An image forming apparatus includes a sheet feed cassette. The sheet feed cassette has a cylinder lock having a cylinder, and a turning unit coupled to the cylinder to be rotatable integrally with the cylinder. A switch switching part of the turning unit is configured to switch a power switch such that the power switch is in an ON state when an inner cylinder of the cylinder lock is at an unlocked position, and the power switch is in an OFF state when the inner cylinder is at a locked position. A cassette locking part of the turning unit is configured to place a sheet feed cassette of a standard sheet feeder in an unlocked state when the inner cylinder of the cylinder lock is at the unlocked position and place the sheet feed cassette in a locked state when the inner cylinder is at the locked position.
Claims5
An image forming apparatus, comprising:
- an image forming apparatus body having a power switch;
- a sheet feed cassette housed in the image forming apparatus body such that the sheet feed cassette is able to be pulled out from the image forming apparatus body;
- an outer cylinder forming a part of a cylinder lock, the outer cylinder being mounted on a wall of the sheet feed cassette located on a front side in a pulled-out direction of the sheet feed cassette;
- an inner cylinder rotatably held in the outer cylinder and configured to be rotated between a first position and a second position about an axis of the outer cylinder by a key inserted into the inner cylinder from the front side in the pulled-out direction;
- and
- a turning unit coupled to the inner cylinder inside the sheet feed cassette such that the turning unit is able to rotate integrally with the inner cylinder,
- wherein:
- the turning unit includes:
- a switch switching part configured to turn in conjunction with rotational motion of the inner cylinder rotated by the key to switch the power switch between an ON state for supplying power to the image forming apparatus body and an OFF state for stopping supply of power to the image forming apparatus body;
- and
- a cassette locking part configured to turn in conjunction with rotational motion of the inner cylinder rotated by the key to switch the sheet feed cassette between a locked state in which the sheet feed cassette is locked such that it cannot be pulled out from the image forming apparatus body and an unlocked state in which the sheet feed cassette is unlocked;
- the switch switching part is configured to switch the power switch such that the power switch is in the ON state when the inner cylinder is at the first position, and the power switch is in the OFF state when the inner cylinder is at the second position;
- and
- the cassette locking part is configured to place the sheet feed cassette in the unlocked state when the inner cylinder is at the first position and place the sheet feed cassette in the locked state when the inner cylinder is at the second position.
