Modular electronic device
View Patent ↗A modular electronic device is provided in a tubular form having a male bayonet connector at one end and a female bayonet connector at the other. A power and communications bus interconnects the connectors. An electronic circuit is located within the device in communication with the bus. Modular devices including an electronic timer, a printer module and a digital camera are provided. A number of the devices can be connected end-to-end to share different functionalities by means of the bus.
1. A modular electronic printing device including:
a cylindrical outer sleeve defining a number of external windows and housing a printhead, the sleeve further defining a media inlet and a media outlet;
a first connector extending from a first end of said sleeve;
a second connector located at an opposing second end of said sleeve;
a plurality of contact strips disposed along the inside of the cylindrical outer sleeve with opposing ends respectively terminating at the first connector and the second connector;
an electronic circuit located within the device and arranged to make electrical contact with medial portions of the contact strips;
a visual display mounted within one of said windows and coupled to the electronic circuit; and
one or more switches mounted in other said windows and coupled to the electronic circuit.
2. The modular electronic device according to claim 1 , including a member disposed between the electronic circuit and the contact strips, the member including an aperture accommodating connections between the electronic circuit and the contact strips.
3. The modular electronic device according to claim 1 , wherein the first connector comprises a male bayonet connector and the second connector comprises a female bayonet connector.
4. The modular electronic device according to claim 3 , including a molding disposed between the electronic circuit and the contact strips and continuous with the male bayonet connector and the female bayonet connector, the molding including an aperture receiving connections between the electronic circuit and the contact strips.
5. The modular electronic device according to claim 4 , wherein the electronic circuit comprises a flexible printed circuit board.
6. The modular electronic device according to claim 5 , wherein the flexible printed circuit board is located between the molding and a support projecting from the female bayonet connector.
7. The modular electronic device according to claim 5 , including an arrangement to lock the flexible printed circuit board fast with the male bayonet connector.
