Claim 0:
1. A pneumatic transmission device adapted for being mounted to
a scanner or a printer, comprising:
a chamber;
a transmitting channel, an initiating end of the transmitting channel being connected with the chamber, the transmitting channel being equipped with a scanning unit or a printing unit;
an air inlet extended upward from a top wall of the transmitting channel, an inside of the air inlet defining a passageway penetrating through a top and a bottom of the air inlet, the passageway being communicated with the chamber;
an air supply device, a top end of the air inlet being connected with the air supply device, the passageway being connected with the air supply device, the air supply device injecting high pressure air into the passageway of the air inlet; and
a paper feeding section having a paper feeding channel, a top and a bottom of the paper feeding channel gradually shrinking towards each other from an importing end of the paper feeding channel to an exporting end of the paper feeding channel, a rear end of the paper feeding section being inserted into the chamber, so that the rear end of the paper feeding section being surrounded by the chamber,
wherein when the high pressure air enters the chamber from the passageway, a first part of the high pressure air flows into the transmitting channel directly, and a second part of the high pressure air flows in the chamber to generate a circular air flow in the chamber, and then the second part of the high pressure air flows into the transmitting channel.
