A method of and an apparatus for supplying a record medium to an electrophotograph printer. The printer includes a photosensitive means on which are formed electrostatic latent images concerning with images to be printed on the basis of images data. The latent images are then converted by applying toner to the latent images to sensible images which are then transferred to the record medium at a transfer position where the sensible images are in opposition to a printable zone of the record medium to form printed images. A time from starting motion of the photosensitive means to a moment when the sensible images have arrived at the transfer position is predetermined and the record medium is supplied into the printer so that a leading end of the printable zone of the record medium arrives at the transfer position when the sensible images have arrived at the transfer position. Moreover, the record medium is supplied into the printer so that the record medium is spaced from the photosensitive means by a distance sufficient to prohibit the toner from clinging to the record medium means until the sensible images arrive at the transfer position.

Method and apparatus for supplying continuous paper to a printer

A comparison-type dimension measurement system in which a laser 1 provides linearly polarized light that is directed by a polarization beam splitter 5 into a microscope system in which a specimen 13 is mounted. The reflected polarized light is rotated 90.degree. by a quarter wave plate 9 and passes through the beam splitter to a multi-element line sensor 19. The laser light is scanned by a rotatable mirror 3 over the specimen. Threshold intensities are determined on indicia of known separation on a reference specimen and used to calibrate the distance measured by the line sensor.

An automatic focusing device for vertical focusing of a specimen 23 in which an enlarging condenser lens 11 is placed between a light source 12 and a half mirror 7 in an automatic focus detecting system so that an enlarged image 24 of the light source is presented to an objective 1 of the focusing microscope M.
