Abstract
A room has a door for closing a door opening in an openable manner. A thermal printer with electronic circuits is installed in the room. An air pressure managing system for the thermal printer includes a door state photo sensor for monitoring a state of the door, and outputs an open signal when the door is open. A dustproofing fan is actuated in response to outputting the open signal, for adjusting pressure of air in the thermal printer, to prevent the thermal printer from being influenced by air flowing from outside the door opening.
Claims12
An air pressure managing system for an electronic equipment installed in a room having a door for closing a door opening in an openable manner, said air pressure managing system comprising:
- a door sensor for outputting an open signal when said door is open;
- and
- an air pressure adjustor for changing over from a first state to a second state in response to outputting of said open signal, and for setting higher a pressure of air in said electronic equipment when in said second state than when in said first state, so as to prevent air flowing through said door opening from entry into said electronic equipment.
