A copying paper processing apparatus comprises a sorter, a stapling device for stapling sheets of copying paper sorted by the sorter, and a device for automatically selecting and setting a sort mode when a staple mode is selected and set. The processing apparatus may comprise a switch for selecting the stapling operation, and a device for automatically selecting and setting a staple mode when the staple selecting switch is turned on and a sort mode is selectively set. The processing apparatus may comprise a device for transmitting a signal indicating that there is no staple needle when the number of staple needles left in the stapling device is a predetermined number greater than the total number of bins of the sorter. The processing apparatus may comprise a device for inhibiting the operation of the stapling device when one of sensors respectively disposed in a paper-receiving base of the stapling device and a sorter bin of the sorter detects that there is no paper.

A connector of the engagement connection type using a plug and socket includes at least a plug pin for the plug and a socket terminal for the socket on one side. A projection of at least one of the plug pin and socket terminal projects toward a connection surface of the other one of the plug pin and socket terminal. The projection is affixed to elastic contact arm that exerts an elastic force toward a contact surface of the other one of the plug pin and socket terminal.

A cathode ray tube (CRT) socket provides for improved performance by increasing the creeping distance between high and low voltages associated with a correspondingly connected CRT. The CRT socket includes a socket body with a cylindrical central hole extending through its front and rear faces, signal connecting means arranged on a concentric circle about the cylindrical central hole, the signal connecting means engaging with signal terminals from the CRT, and an insulating cover portion arranged on the same concentric circle as the signal connecting means, the insulating cover portion having a high voltage connecting means for engaging with a focusing terminal of the CRT. The signal connecting means is constructed by forming a recessed signal contact portion in the front face of the socket. A plurality of signal contact holes are formed in the recessed signal contact portion of the front face. Each of the plurality of signal contact holes are spaced apart at a predetermined interval. The high voltage connecting means includes a recessed high voltage contact portion which is formed by recessing a front face portion of the socket and a high voltage contact hole formed on the recessed face. The holes formed in the recessed portions of the high voltage connecting means and the signal connecting means engage the terminals on the neck of the CRT. The recessed signal contact portion and the recessed high voltage contact portion are separated from each other by a groove portion which extends to the front and rear faces of the socket body. Creeping distance is increased by separating the high and low voltage (signal) portions of the socket by the groove portion.

A recovery method for recovering proper operation of an ink jet recording head having a plurality of discharge ports and a plurality of thermal energy generating elements each corresponding to each of the discharge ports includes providing a recovery device for performing recovery according to a first recovery mode for only applying pressure to the discharge ports to effect suction of ink from the discharge ports while the discharge ports are capped by a capping device, and a second recovery mode for concurrently applying pressure to the discharge ports and driving the thermal energy generating elements to forcibly exhaust ink from the discharge ports while the discharge ports are capped by the capping means. The method also includes selectively performing recovery according to one of the first recovery mode and the second recovery mode.
摘要:
A head for discharging yellow ink, magenta ink, cyan ink and first black ink having a relatively fast penetration velocity to a recording medium and a head for discharging second black ink having a relatively low penetration velocity are used to print an image. When a black image is adjacent to a color image, the black image is formed by using the first black ink, and when the black image is not adjacent to the color image, the black image is formed by using the second black ink. A black ink and a plurality of color inks having a different penetration velocity to a recording medium than that of the black ink are also used to print an image. Whether a color image area is present in the vicinity of a black image area of record data or not is determined, and whether the black image area is to be formed by the black ink or by the color inks is decided in accordance with the determination result, and when the black image is to be formed by the color inks, the color inks are used based on a mask pattern pseudo-randomly prepared to make the change in tonality less recognizable.

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 means 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 means 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 means 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.

Random masks each having a given size and defining a random array of non-record pixel locations and record pixel locations are placed in association with record areas in mask registers. Using the placed masks, record data is thinned-out and supplied to a recording head. An image is then recorded. Thus, since thinning-out masks do not have periodicity, any inherent density nonuniformity loses periodicity. Consequently, high-definition images can be produced.
