    摘要： A liquid discharge head includes nozzles that discharge liquid droplets, individual channels in communication with the nozzles, a liquid introducing part in communication with the individual channels, a common liquid chamber that supplies liquid to the individual channels, and a filter part arranged between the common liquid chamber and the liquid introducing part. The filter part has filter holes for filtering the liquid over a range of the individual channels in a nozzle array direction. The filter part has at least one reinforcement rib arranged in the nozzle array direction. The reinforcement rib is partially arranged over the range of the individual channels in a direction perpendicular to the nozzle array direction. Filter regions divided by the reinforcement rib are arranged to be in communication via a communication region where the reinforcement rib is not arranged, and the filter holes are arranged at the communication region.

    摘要： In a liquid drop ejecting head including a diaphragm, a channel member, and a nozzle plate which are laminated in this order, interface surfaces of the channel member and the diaphragm are bonded by an adhesive. The diaphragm is formed to have a laminated structure in which the number of lamination layers is varied at different locations. The diaphragm includes an opening and a filter part, the filter part having plural filtering holes formed in the opening for supplying a liquid to pressurizing liquid chambers of the channel member. A side wall of the channel member disposed to contact or located in a vicinity of the filter part, and a thick-walled portion containing the largest number of lamination layers in the diaphragm do not overlap with each other in a laminating direction.

    摘要： There is provided a driving circuit which is simple and has a small occupied area. A shift register circuit of the present invention includes a plurality of register circuits. Each of the register circuits includes a clocked inverter circuit and an inverter circuit. Both are connected in series with each other so that an output signal of the clocked inverter circuit becomes an input signal of the inverter circuit. Further, the register circuit includes a signal line by which an output signal of the inverter circuit is transmitted. Since a number of elements are connected to the signal line and parasitic capacitance is large, it has a high load. The shift register circuit of the present invention uses the fact that since the parasitic capacitance of the signal line is large, it has a high load.
