Abstract: A printer includes an apparatus main body, an inner door unit, a main body gear, a transmission gear, and a lock mechanism section. The lock mechanism section locks the inner door unit against the apparatus main body and unlocks the inner door unit from the apparatus main body. The lock mechanism section includes a counter-engagement shaft which is long in a Y-direction, a lock lever having an engagement surface configured to engage with the counter-engagement shaft, and a tension spring that applies force to the lock lever to enable the engagement surface to change in position from a first posture to a second posture. In a closing operation, the engagement surface changes position to the second posture while shifting the position of contact with the counter-engagement shaft, and applies, to the counter-engagement shaft, a pull-in force for moving the inner door unit to a closed position.

Abstract: A printer for intermittely feeding printing sheets to which a photoconductive microcapsule is applied in a sheet feeding direction and printing images on the printing sheets, includes a frame, an exposure head which is supported by the frame and irradiates light to the sheets to form a latent image thereon; and a pressing and developing head which is supported by the frame so as to reciprocate in a scanning direction intersecting the sheet feeding direction on the downstream side of the exposure head with respect to the sheet feeding direction and applies pressure to the latent image forming part of the sheet in cooperation with a sheet supporting means disposed on the rear surface side of the sheet to develop a latent image.

Abstract: A method for printing photographic quality images downloaded to a printer comprising; providing a light-tight film pack containing photosensitive imaging media, the film pack having a severable line of on a face thereof which defines a flap, the flap providing access to the media when the flap is opened; providing a cartridge of a size and shape to fit into a cartridge-access opening in the printer, the cartridge comprising a tray for accepting the film pack; inserting the film pack into the cartridge; inserting the cartridge containing the film pack into the cartridge-access opening in the printer; severing the film pack along the severable line to free the flap; opening the flap to access the media; advancing the media into the printer; and exposing and developing the media to provide a photographic quality print.

Abstract: A method of producing a boron-based compound represented by general formula (1) including a first step of reacting lithium, magnesium or a compound containing lithium, a compound represented by general formula (2), and a compound represented by general formula (3): R.sup.2 --Y to produce a borate metal salt represented by general formula (4), and a second step of adding to the borate metal salt an onium halide represented by general formula (5): Z.sup.+ .multidot.X.sup.- to effect ion exchange reaction (the symbols in the formulae have the same meanings as described in the specification).According to the production method of the present invention, a high purity boron-based compound represented by the general formula (1) above useful as a photopolymerization initiator and a light-absorbing decolorizing agent can be obtained in a short time and a high yield as compared with the conventional method.
