The carriage mounting the print head, for a printer, is supported at an upper guide bar with an upper bearing and at a lower guide bar with a lower-right bearing and a lower-left bearing. The printing device prints characters while driving the print head in reciprocal movement along the guide bars. The lower-left bearing has an eccentric center relative to the axis of the lower-guide bar. A lever fitted on the lower-left bearing allows the operator to rotate the lower-left bearing relative to the axis of the lower guide bar to adjust the height of print.

An image recording apparatus records an image on an elongated continuous form photosensitive recording medium capable of receiving a latent image of an output image to be formed, and a cut sheet type of a developer recording medium provides an output image upon reaction with the latent image on the photosensitive recording medium. The recording apparatus includes an exposure portion for exposing the elongated continuous form photosensitive recording medium fed along the recording medium feeding path to a light image to form the latent image thereon. The exposure portion includes an exposure position whereat a leading edge of an unexposed portion of the photosensitive recording medium is located prior to imaging. A developing portion is disposed downstream of the exposing portion with respect to the recording medium feeding path and develops the exposed photosensitive recording medium superposed with the developer recording medium. A separating portion is disposed downstream of the developing portion with respect to the recording medium feeding path and separates the exposed photosensitive recording medium from the developer recording medium. A controlling portion controls a developer feeding portion and a photosensitive recording medium feeding portion so that the time required to feed a trailing edge of the developer recording medium from a position downstream of the separating portion to a discharged position is at least as long as the time required to feed a leading edge of an unexposed portion of the photosensitive recording medium from a position downstream of the separating portion back to the exposure position.

An image forming apparatus for forming a visible image using an elongated photosensitive recording medium, comprising an exposing unit for exposing the photosensitive recording medium to light in an exposure process to form a latent image thereon, a pressure-developing unit for developing the latent image into a visible image in a developing process, a sheet feeding unit for feeding the photosensitive recording medium through the exposing unit over the pressure-developing unit along a sheet feed path, a sheet rewinding unit for rewinding the photosensitive recording medium after the developing process to feed the photosensitive recording medium to a predetermined position in the sheet feed path, thereby performing a sheet rewinding operation, and a sheet feed control unit for selecting one of at least two modes of first and second modes such as speedy and saving modes and controlling the sheet rewinding unit to carry out the sheet rewinding operation only when the second mode is selected.

A sheet supplying device for supplying an uppermost sheet of a stack of sheets in a sheet cassette used in an image forming apparatus includes suction cups movable into and out of contact with the uppermost sheet in the sheet cassette, an evacuator for developing a vacuum in the suction cups to enable the suction cups to attract the uppermost sheet, a moving member for upwardly and downwardly moving the suction cups to pick up the sheet from the sheet cassette, a sheet feeding member for feeding the sheet from the moving member along a sheet feed path, and a control system for judging on the basis of a detection signal from each sensor for detecting an image forming error provided in the image forming apparatus whether the error occurs during the sheet supplying operation, and when judging that the image forming error occurs during a sheet supplying operation, the control unit ceasing the sheet supplying operation and controlling the driving of at least one of the suction cups, the evacuator, moving member and the sheet feeding member so that at least one of those members carries out a predetermined operation selected from the series of operations to be performed by at least one of the members.

A sheet storage case for storing therein a stack of sheets. The sheet storage case is assembled into a sheet feeding device which feeds out an uppermost sheet of the stack of sheets. The sheet storage case includes a bottom plate, a first positioning member fixedly secured to the bottom plate and a slidably movable second positioning member provided in the bottom plate. The second positioning member has a sheet receiving portion for receiving the stack of sheets. The second positioning member is movable toward and away from the first positioning member. To mount a stack of sheet on the sheet storage case, the second positioning member is moved away from the first positioning member, the sheets are placed on the sheet receiving portion, and then the second positioning member is moved toward the first positioning member. The side edges of the sheets are aligned, because the sheets are fittedly interposed between the two positioning members. The uppermost sheet is taken out by a mechanism which includes a suction cut which is brought to contact with the uppermost sheet to attract the latter. The suction cup to which the sheet is attracted is swung in the position above the sheet storage case to separate the uppermost sheet from the reminder.

Sheet storage case for use in image recording apparatus

A sheet feed mechanism has an array of suction cups into and out of contact with an uppermost one of stacked sheets in a sheet cassette. After the suction cups are held against the uppermost sheet, a vacuum is developed in the suction cups to enable the suction cups to attract the uppermost sheet. Then, the suction cups are lifted with the uppermost sheet attracted thereto, and a leading end of the attracted and lifted uppermost sheet is nipped, and the sheet is delivered into a sheet feed path. When the suction cups are lifted, they are angularly moved about an axis to cause the leading end of the attracted uppermost sheet to be obliquely separated from other stacked sheets.

Disclosed herein is a laser scalpel which uses a krypton beam or a ray of light projected from a mercury lamp having a wave-length in the range of 3,950-4,200A as a guide light converging at the focal point or in the vicinity of the focal point of a laser beam for a surgical operation, for indicating focal point of said laser beam, which is equipped on its manipulator with a radiation detector or detectors enabling the detection of hematoporphyrin or isotopes built up in advance in the site of a tumor at said focus or in the vicinity thereof and to thus detect the tumor site at the time of irradiation of said laser beam for surgical operation and which makes it possible to simultaneously perform both diagnosis and treatment of the tumor.
