A watertight connection includes a male side and female side pair of terminal fittings. Each of the terminal fittings is mounted to an end part of an electrical line. Plug housings having male side and female side terminal fittings of two poles are correspondingly mounted, male side-to-male side and female side-to-female side. Insulation members each house a rear end part of a plug housing and an end part of an electrical lines. A sealing material member prevents moisture from penetrating into the insulation member. Openings, which expose the front end part of each plug housing outside of the insulation member, are formed in an inner wall surface of the insulation member. An outer circumferential surface of the rear end part of each of the plug housings is brought into close contact with the sealing material member to couple the plug housings and the insulation member in a watertight state.

A connector assembly making an electrical connection through the mutual engagement of a pair of connectors. One of the connectors has a flexible lock arm, and the other connector has a lock receiver that links to this lock arm. The connector that has the lock arm also has an arm protection part that extends over a substantial portion of an outer surface of the lock arm.

In a recording apparatus for effecting recording with a recording head on a recording medium, a temperature detector provided on a control circuit board of the recording apparatus detects a temperature at the board, and a timer measures a first activation time of electric power supply to the control circuit board for a control not involving a recording operation. The timing of reading the temperature detected by the temperature detector, as well as a correction value for the thus read value, are determined according to the first activation time measured by the timer.

A CRT socket has reduced thickness but maintains favorable insulation without requiring a change in the construction of the neck of a CRT. The CRT socket arrays a plurality of signal and focusing contact sockets about a central hole. The ends of signal pins of a CRT and of the focusing contact sockets passing partly through an enlarged hole in a circuit board, whereby the height of the CRT socket is reduced.

A paper feed operation is performed by a width less than one pixel (½) in addition to an integer multiple number of pixels (n/2) with respect to a basic number of pixels inherent to an ink jet recording apparatus having a multi nozzle head having n nozzles. When a plurality of pixel recording operations are performed for a single pixel region, ink dots land within a distance less than one pixel unit (½). Thus, a variation in ink surface density on a recording sheet in an overlapping print operation is reduced, thereby efficiently increasing the image density, and preventing blurring by promoting absorption and evaporation of an ink to and from a paper sheet.

An ink jet recording apparatus comprises a recording head having discharge ports to discharge ink; an ink tank containing ink to be supplied to the recording head; and device for performing predischarges to stabilize ink discharges from the recording head. In this apparatus, the recording head is provided with a discharge unit to discharge plural kinds of ink, and the device for performing predischarges operates predischarges from all the discharge ports, only from the discharges ports in the vicinity of each end of the discharging units, and from all the discharge ports in that order at least for predischarges from discharging unit having relatively thin ink. With such head and device for performing predischarges, it is possible to remove mixed ink after suction recovery with a lesser amount of ink consumption, and execute a high quality recording stably at all times.

An ink jet recording apparatus for performing recording using a recording head for ejecting an ink from a plurality of ejection orifices, includes a print control unit for performing a print operation while switching a print mode between a thin multi-pass print mode for sequentially recording divided recording data in a plurality of number of times of relative scan operations of the recording head with respect to a single recording area, and a 1-pass print mode for recording all recording data in a single relative scan operation of the recording head, and an eject quantity control unit for controlling the eject quantity of the ink ejected from the recording head so that a total ink quantity on the recording area in the thin multi-pass print mode is larger than a total ink quantity in the 1-pass print mode.
摘要:
An ink jet recording device includes scanning means for scanning ink jet recording heads in a scanning direction, each of the recording heads having plural ink discharge generating elements and plural discharge ports associated therewith, the discharge ports being adapted to perform a recording operation within a recording area which is a total area covered by the discharge ports during one scanning operation, supplying means for supplying recording signals corresponding to the recording area to a group of the ink discharge energy generating elements, and conveying means for conveying a recording medium relative to the recording heads. A control means controls the ink jet recording heads, supplying means and conveying means so that when the control means operates in a first recording mode, a recording within the recording area is completed in a single scanning operation, and when the control means operates in a second recording mode, the recording within the recording area is completed by plural scanning operations such that the recording area is subjected to the overlapped recordings by different discharge ports. The control means selects the recording mode according to a condition relating at least to a material quality of the recording medium.
