A process camera includes: an original holder; a lens for projecting an image of the original on an image forming plane; a frame having an opening defining the image forming plane; a focusing glass attached to the frame movable between a portion covering only a part of the opening of the frame and an open position freeing the opening for forming an image of the original of the surface thereof; a vacuum board for holding a film thereon; and a member for mounting to the frame the vacuum board rotatably around a predetermined axis of rotation between a closed position covering all of the opening and a position covering only a part of the opening. Since the area of the focusing glass is selected to be smaller than the area of the opening, the area required by the focusing glass at the open position is small. The axis of rotation of the vacuum board is provided crossing the opening, but not along sides of the opening. The axis of rotation of the vacuum board is provided at a position other than an end portion of the vacuum board.

When, in a heat-sensitive recording material comprising a substrate and a heat-sensitive recording layer provided on the substrate and containing an ordinarily colorless or light-colored dye precursor and a color developer capable of allowing the dye precursor to develop a color by reacting with the dye precursor when heated, the heat-sensitive recording layer further contains 1,2,3-tris(3-butyl-4-hydroxy-6-methylphenyl)butane, the resulting heat-sensitive recording material has excellent sensitivity and image stability.

An image forming apparatus includes a media roll, art image forming device, and a feeder. In the media roll, a printing medium having an adhesive face is wound in a roll shape. The image forming device forms an image on the printing medium. The feeder feeds the printing medium. The feeder includes a protection belt and a pair of rotary bodies. The protection belt presses against and protects the adhesive face of the printing medium. The pair of rotary bodies sandwich and press the printing medium and the protection belt between the pair of rotary bodies. An approach angle of the printing medium is within a range from 0° to 30° and is formed by the printing medium drawn from the media roll and approaching to between the pair of rotary bodies and an opposing face of the protection belt opposing the image forming device.

An image forming apparatus includes an image forming unit, a conveyance unit, and an adhesive-surface guide unit. The adhesive-surface guide unit includes a second rotary body and an adhesive-surface guide member. The second rotary body is disposed at a position downstream from a first rotary body of a pair of rotary bodies of the conveyance unit in a conveyance direction. The adhesive-surface guide member is wound around the first and second rotary bodies to guide an adhesive surface of a print medium. The adhesive-surface guide unit is configured to press the adhesive-surface guide member against the adhesive surface, sandwich the print medium and the second rotary body between the pair of rotary bodies, move the print medium and the second rotary body together, and separate the adhesive-surface guide member from the adhesive surface at a side of the adhesive-surface guide unit at which the second rotary body is disposed.

An image forming apparatus includes a roll body including a print medium wound around, the medium having an adhesive face, an image forming unit to form an image on the adhesive face, a conveyance unit having a pair of a conveyance rotor and an opposed rotor to convey the medium with the medium interposed between the conveyance rotor and the opposed rotor and an adhesive face guide unit to guide the medium when the conveyance unit returns the medium in a return direction opposite a conveyance direction of the medium. The adhesive face guide unit has a downstream rotor disposed downstream from the opposed rotor in the return direction and an endless adhesive face guide member wound around the opposed rotor and the downstream rotor. The adhesive face guide member is configured to receive and guide the adhesive face of the medium returned, in a separable state.

An image forming apparatus includes an apparatus body, a print medium, a conveyance unit, art image forming unit, a cutter unit, a holding unit, a sensor, and a controller. The print medium has an adhesive face with no separation sheet. The cutter unit cuts the medium having an image formed into a print medium piece. The holding unit is configured to hold the piece in a state in which the piece is drawable from outside of the body. The holding unit has a surface separatable from an adhesive face of the piece to hold the adhesive face of the piece. The sensor detects presence or absence of the piece held by the holding unit. After the sensor detects that the piece is drawn out, the controller controls the conveyance unit to convey the medium to the holding unit and controls the holding unit to hold the medium.

A sheet feeding device includes a sheet feed cassette, a bottom plate and an end wall mechanism. When the number of recording media sheets decreases, the bottom plate hinged at a trailing edge thereof rises about the hinged end to keep the top sheet of the recording media sheets in contact with a sheet feed roller. The end wall mechanism includes a first urging member, a first pressing member, a support member, and a second pressing member, and aligns and presses the trailing edge of the recording medium. The first pressing member urged by the first urging member and supported by the support member presses the trailing edge of the recording medium. The second pressing member urged by the second urging member moves down due to the weight of the recording medium on the second pressing member and moves up when the number of the recording media sheets decreases.

The sheet thickness detector includes a fixed member, a displacement roller disposed opposite the fixed member and movable in such a linear direction as to be contacted with or separated from the fixed member when the sheet passes through a nip therebetween, bearings rotatably supporting a shaft of the displacement roller, a displacement member movable in the linear direction in conjunction with the displacement roller and integrated with at least one of the bearings, and a displacement sensor operatively connected to the displacement member and detecting displacement of the displacement member. The thickness of the sheet passing through the nip is determined based on the amount of displacement of the displacement member.

The object of the present invention is to provide a LED illumination system which does not cause heat generation and damage, even when a straight-tube fluorescent lamp is mistakenly fitted into a straight-tube fluorescent lamp luminaire in which the fluorescent lamp ballast has been replaced with a LED lighting device.The LED illumination system according to the present invention is configurated in such a manner that the LED lighting device is installed in an existing straight-tube fluorescent lamp luminaire, and the LED lamp is connected to the existing sockets. The characteristic of the output from the LED lighting device connected to either inter-terminal section A on the ends of the LED lamp is to be different from that of an existing fluorescent lamp lighting device. The LED lamp is provided with lighting device output detection means for detecting the output from the LED lighting device and also with protection means for cutting off the input to the LED lamp when the output detected by the lighting device output detection means is outside of a predetermined range.

In a recording medium conveyer, a driver drives a feeding member and a conveying member provided downstream from the feeding member in a recording medium conveyance direction independently. A controller stops driving the feeding member when a first time period elapses after a recording medium reaches the conveying member. When a selector judges that the thickness of the recording medium identifies the recording medium as thin paper, the controller does not drive the feeding member after the controller starts driving the conveying member, and when the selector judges that the recording medium has a thickness greater than a thickness of the recording medium that identifies the recording medium as thin paper, the controller restarts driving the feeding member no later than when the controller starts driving the conveying member.
