An ink jet recording head () comprising edge shooter type head units () each having a head chip provided with a nozzle ejection surface, a positioning plate () for arranging the head units () in parallel to each other, inclined against a line arranging direction. The positioning plate () arranges the head units () in parallel to each other, inclined against the line arranging direction, and the angle of the inclination is set so that a nozzle interval, in the line arranging direction, of two nozzles () corresponds to a predetermined resolution, the two nozzles being adjacent to each other on a straight line on the nozzle ejection surface.

An outputting apparatus comprises: a changing circuit to change a bit map font in accordance with a resolution of an outputting mechanism in the case where a resolution of the bit map font to be generated differs from the resolution of the outputting mechanism; a developing circuit to develop dot pattern information of the bit map font changed by the changing circuit; and an outputting device to output the dot pattern information developed by the developing means. The changing circuit executes a smoothing process by interpolating one dot into a zigzag portion of a character pattern. The bit map font is a down-load font.

Outputting method and apparatus

An electronic equipment has a central processing unit (CPU), a first memory accessable by the CPU, a first setting circuit for holding a signal representative of a rated access time of the first memory and a removable auxiliary memory which includes a second memory accessable by the CPU and a second setting circuit for holding a signal representative of a rated access time of the second memory.

Electronic equipment having controllable access times for detachable

An output apparatus for receiving code data from a data source of a host computer and developing it into pattern data and outputting the data. The apparatus includes a pattern generator to generate pattern data; a memory to store the pattern data generated by the pattern generator and obtained in response to an output operation as a font cache; and a controller for controlling the memory such that when an amount of available memory is less than an amount sufficient to store data which is newly input and which has higher priority of storage than the pattern data stored in the cache, the stored pattern data is deleted and the newly input data is stored. An auxiliary character font, form data, or a macro instruction is used as data which is newly input. The pattern data of the font cache in the memory is deleted on the basis of the priority. The pattern data is a dot matrix font pattern which was developed from a nondot matrix font.

Output apparatus

An image data output apparatus is connected to an image scanner and a data processor (host computer). The image data output apparatus includes interfaces, a data converter, a video signal generator, an LBP engine unit, and the like. Multi-level image data scanned by the image scanner is converted by the data converter into data having a desired data format corresponding to the data processor. The converted data is output to the data processor through the corresponding interface. Meanwhile, the scanned image data is also supplied to the video signal generator and is converted to a drive signal for driving a semiconductor laser of the LBP engine unit.

In a code converting device for converting first code data of scattered code form into second code data of consecutive data form, the first code data are divided at least into a first bit group and a second bit group, and the first bit group is supplied to a first memory to obtain first output data and second output data. The first output data and the second bit group are supplied to a second memory to obtain third output data. The second output data and the third output data are processed in a data processing unit to obtain the second code data.

Device for converting code signals of one bit number into a code signal

In reading out character dot patterns corresponding to character code signals from a dot pattern store therein a number of character dot patterns representing characters, there is provided a store therein position signals representing positions whereat the character dot patterns are stored in said dot pattern store, so that the position signals are first read out from the store by the character code signals and the corresponding character dot patterns are read out from said dot pattern store by the position signals.
