An extrusion device of a three-dimensional printer includes a ratchet, a spray head, an idler, a feeding wheel and an optical detection mechanism. The spray head and the idler are disposed adjacent to the ratchet. A thermofusible material is provided to the spray head by the feeding wheel. The optical detection mechanism includes a guiding element and an optical detecting assembly. The guiding element is disposed between the ratchet and the feeding wheel along a feeding path. The optical detecting assembly is disposed adjacent to the guiding element. The thermofusible material is guided by the guiding element and partially disposed on a detecting area. A waveband light is emitted to the detecting area by the optical detecting assembly. The image produced by the reflection of the waveband light reflected by the detecting area is detected by the optical detecting assembly. Therefore, the operation of the equipment is completely monitored.

Extrusion device of three-dimensional printer and optical detection mechanism thereof

A communication device for storing personal or department data is disclosed. A communication machine is installed with an operating panel with a one-touch dial function and a liquid crystal display, which are connected to a circuit control unit. A reading machine is installed in the communication machine. An internal circuit of the reading machine is communicated with the circuit control unit; and at least one card-inserting seat is installed in the communication machine for being inserted by at least one memory card. Each memory card serves to store personal data or department data, use setting values of a device, or data of a telephone book. Each card-inserting seat is connected to the internal circuit of the reading machine. When an operator is desired to user the device, it is only needed to insert the memory card into the card-inserting seat. Thereby, the reading machine reads the data in the memory card, then, the one-touch dial function in the operating panel is replaced by the memory card. On the contrary, the operator may use the functions on the operating panel of the communication machine.
