A packet recording/reproducing system is provided which records or reproduces packets on or from tracks formed in time sequence on a magnetic tape. In a recording operation, the packet recording/reproducing system adds to input packets time stamps whose values are synchronous with packet arrival time control clocks produced by the system. The timing with which the packets are recorded on the magnetic tape is controlled by the arrival time control clocks so that a given number of the packets inputted at high data rate are recorded within a one-track area, a two-track area, or a one-track over area defined across at least two of the tracks, thereby minimizing the loss of capacity of the magnetic tape.

An ink-jet recording apparatus includes an ink tube and an air discharge tube which has a cylindrical shape and an inside diameter that is larger than an outside diameter of the ink tube. The air discharge tube is provided so as to surround the ink tube. Therefore, a circular enclosed space is provided around the ink tube, between the air discharge tube and the ink tube. A pressure reducing device is connected with the enclosed space to reduce pressure therein. By actuating the pressure reducing device, the pressure in the enclosed space is reduced. Thus, air contained in ink is sucked into the enclosed space, in which the pressure is reduced, through a wall of the ink tube, and thus, generation of air bubbles are restricted in the ink tube.

A device for preventing contamination of a print sheet and the reduction in the effectiveness of a scorotron type charger by free toner and paper particles. The device includes a paper dust eliminator extending the length of a photosensitive member and a wiping mechanism at each end of the photosensitive member for removing free toner that has accumulated there. Further, a partition that separates the developing section from the charger can be provided to further reduce free toner from attaching to the charger.

A developing roller 19 is formed of a blend material produced of silicone rubber and EPDM, which has good abrasion proof, and subjected to a rubbing process to rub a surface of the developing roller 19 until convex portions 19A formed on the surface become less than two times a particle diameter (5-10 .mu.m) of toner T, i.e., 10-20 .mu.m. Accordingly, the surface condition of the developing roller is not changed for a long time and thus the toner T can uniformly be carried on the surface of the developing roller 19, forming a uniform thickness toner layer, thereby enabling to uniformly charge the toner layer. Uniformly charged toner layer on the surface of the developing roller 19 thus makes it possible to develop an electrostatic latent image formed on a photosensitive drum 12 with uniform toner density, causing no difference in toner density. When the developed image on the photosensitive drum 12 is transferred to a sheet 50, a resultant image with uniform image density can be formed on the sheet 50.

A method for detecting deterioration of solder paste printing includes defining a check pattern region on a portion of the printed circuit board PC separated from the electrical circuit, forming fine pitch check through-holes 8a in the metal mask 7 with a pitch finer than that of the electrical circuit within a region of the metal mask corresponding to the check pattern region, printing solder paste 9 onto the check pattern region through the fine pitch check through-holes of the metal mask, monitoring for defects in the printed check pattern and detecting a defect in the check pattern region before the solder paste printing onto the electrical circuit has deteriorated. The method enables maintenance of the best condition of the solder paste printing onto the electrical circuit.

An image recording apparatus using a microcapsule sheet on which a latent image is formed. The microcapsule sheet is accommodated within a sheet roll cartridge detachably provided to a main frame, and a take up means for winding light-exposed microcapsule sheet thereover. The cartridge and the take-up means are geometrically positioned at an upper portion of the main frame, so that these are easily assembleable and disassembleable. Preferrably, a link mechanism is provided which connects a cover member to the cartridge. The link mechanism provides disengagement of the cartridge from the main frame upon opening of the cover member, and provides an engagement therebetween upon closing thereof. Further, additional link mechanism is provided between the cover member and a separation roller unit. The separation roller unit is moved to a first direction where the roller is separated from the microcapsule sheet when the cover member is opened. The unit is moved to a second direction where the roller is in contact with the microcapsule sheet when the cover member is closed.
