Abstract
An optical scanning apparatus including a chassis having a panel, the panel having an opening defined therethrough. The apparatus has a scanner carriage which is moveably supported within the chassis. A carriage locking device includes an elongated locking member which is moveably disposed within the opening in the panel and, when the locking member is moved in a downward direction within the opening, the locking device secures the scanner carriage in a relatively fixed position with respect to the chassis.
Claims23
An optical scanning apparatus comprising:
- a chassis having a panel, the panel having an opening defined there through;
- a scanner carriage moveably supported within the chassis;
- a carriage locking device comprising a locking member which is moveably disposed within the opening in the panel and, when moved in a downward direction within the opening, secures the scanner carriage in a relatively fixed position with respect to the chassis;
- the scanner carriage comprises a locking pin supported thereon;
- and
- the carriage locking device further comprises a locking bar supported on the locking member, the locking bar being shaped to engage the locking pin when the locking member is moved in the downward direction within the opening in the panel;
- the scanner carriage comprises a plurality of locking pins supported thereon;
- and
- the locking bar is shaped to engage the plurality of locking pins when the locking member is moved in the downward direction within the opening in the panel.
An optical scanning apparatus comprising:
- a chassis having a side panel, the side panel having a connector opening defined therein;
- a cover supported on the side panel and moveable from a first position wherein the connector opening is exposed, to a second position wherein the connector opening is covered;
- a scanner carriage moveably supported within the chassis;
- and
- a carriage locking device which is actuated by the cover and which secures the scanner carriage in a relatively fixed position with respect to the chassis when the cover is in the second position.
An optical scanning apparatus comprising:
- a chassis having a side panel, the side panel having a connector opening defined therein;
- a scanner carriage moveably supported within the chassis;
- and
- a carriage locking device which is actuated when no connector is placed in the connector opening to thereby secure the scanner carriage in a relatively fixed position with respect to the chassis.
An optical scanning apparatus comprising
- a chassis;
- a scanner carriage moveably supported within the chassis;
- and
- a passive scanner carriage locking device which is actuated when the chassis is put into a configuration which indicates that the chassis can be subjected to movement to thereby secure the scanner carriage in a relatively fixed position with respect to the chassis;
- wherein:
- the chassis defines a connector opening;
- and
- the passive scanner carriage locking device is actuated when no connector is inserted into the connector opening.
