A pair of thin-walled portions 6 are formed on packing 3 between a seal lip portion 92 and a vent hole in a connector housing 1. A pair of short-shot preventing ribs 8 are located contiguously to the thin-walled portions 6. The short-shot preventing ribs 8 are formed in a mold between the seal lip portion 92 and the vent hole (vent core 5), and a packing material is allowed to reach the vent hole via a narrow gap between each short-shot preventing rib 8 and the connector housing 1. Consequently, the flow resistance of the packing material increases, so that the packing material is preferentially filled in seal lip portions 91 and 92. The short-shot preventing ribs 8 may be formed on the connector housing 1 instead of the mold. The pair of short-shot preventing ribs 8 are formed, and the packing material is allowed to reach the vent hole.

A data recording/reproducing apparatus in which plural disc-shaped recording/reproducing means are run in parallel. The apparatus is designed for avoiding the risk of the write/readout unit being changed in size to lower the transfer rate to raise the cost brought about by changing the number of the disc-shaped recording/reproducing means. A disc array unit 11 accesses video data of 163840 bytes equal to 40 times as many as 4096 bytes and audio data of 8192 bytes equal to twice as many as 4096 bytes to a data driving unit 11D made up of seven HDDs with a size of, for example, 3584 bytes. An accessing control unit 12 controls data accessing to the disc array unit 11. A data adjustment unit 25 appends a volume of nonsensical data (padding data) equal to a multiple of 3584 bytes at the time of recording, while taking out data excluding the padding data during reproduction in terms of 4096 bytes as a unit.

A hot-melt type ink jet printer includes a nozzle head for ejecting a hot-melt type ink onto a sheet. The printer has a sheet feed passage defined by, in order from an upstream side in a sheet feeding direction, a sheet supply roller, a preheat platen, a sheet feed roller, a main platen, a cooling platen, discharge roller and a sheet discharge opening. The preheat platen and main platen have preheater and main heater, respectively, and these platen and the cooling platen are supported on a frame. A first suction port is formed between the main platen and the cooling platen and a second suction port is formed between the cooling platen and the frame. A power board and a cooling fan is provided within the frame for cooling the power board. By rotation of the cooling fan, air is introduced from the sheet discharge opening into the frame through the first and second suction ports to also cool the cooling platen and the heating platen.

An ink jet printer is provided with: an ink discharge device for discharging ink, having (i) a body prescribing an ink flow path through which the ink is supplied, a plurality of ink storing chambers each connected to the ink flow path in which the supplied ink is temporarily stored and a plurality of ink discharge holes connected to respective one of the ink storing chambers though which the temporarily stored ink is discharged, and (ii) a plurality of piezoelectric elements for selectively changing capacities of the ink storing chambers; a driving voltage generating device for generating a driving voltage having a pulse-like waveform, which causes the ink to be discharged from each of the ink discharge holes by deforming the respective one of the piezoelectric elements; a plurality of analog switching devices for selectively opening and closing each current-carrying path, through which the driving voltage is supplied to the respective one of the piezoelectric elements; a power source voltage supplying device for supplying a power source voltage to the analog switching devices; a driving voltage adjusting device for changing at least one of a slope and an amplitude of the waveform of the driving voltage; and a power source voltage adjusting device for changing the power source voltage.

A print head assembly having at least two print heads each having at least one nozzle for ejecting ink toward a print medium and being movable in a scanning direction substantially orthogonal to a conveyance direction of the print medium, is disclosed. The print heads are arranged in the scanning direction in such a manner that print time from at least one of the print heads is different from print time of at least one other print head. The nozzle interval between an adjacent pair of print heads has a value that is differentiated from the product of any natural number and the inverse number of a resolution, by, for example, adding to or subtracting the inverse number of the product of the resolution and a natural number other than 1, wherein the natural number is the number of print heads.
