The present invention is adapted to form a finger table for supporting and locating a finger to be authenticated by touching the front part of the finger in a case, make the case closed at parts corresponding to the tip and the base of the finger to be authenticated and parts corresponding to left and right sides of the finger, make the case opened at parts corresponding to the front part and the backside of the finger, and form an imaging range of imaging means such as an imaging element in the parts corresponding to the left and right sides of the finger. With the configuration, a finger vein pattern inputting device with high operability and authentication accuracy reserved is provided.

Personal authentication device

A character generating system drives a printer engine to print characters in response to an instruction from a host computer. The characters to be printed by the printer information are normally generated on the basis of dot data stored in a cache memory via a print map memory under the control of e.g. a microprocessor. Since the cache memory is a volatile memory, its contents may be erased due to disconnetion of the power supply. In order to speed up the regeneration of the dot data in the cache memory, information relating to the dot data is stored in a non-volatile memory, and on reconnection of the power supply, that information is used together with vector information in a vector memory for regeneration of the dot data in the cache memory.

Character generation

In a printer system wherein one or a plurality of host computers use in common a single printer such as an expensive photo printer for electronic publishings of desktop publishings such as word processors, character format data of characters to be printed out is stored beforehand as character pattern data at a printer controller of the printer system. The host computer either stores minimum necessary character pattern data for monitor display or control, or stores no character pattern data. The character pattern data necessary for monitor display or control are used by transferring them from the printer controller to the host computer.

Printer system and operating method therefor

A video signal generating apparatus for a laser beam printer including a dot counter which counts the dots along the horizontal side of a recording area, and a raster counter which counts the dots along the vertical side of the recording areas. In accordance with the outputs of these counters, a character pattern memory produces a character print dot signal, while a set value representing a ruled line size is calculated from the outputs of the dot counter and the raster counter, thus producing a ruled line signal. These two signals are combined to make up a video signal.
