Optical writing

The invention relates to an optical writing unit by means of which light images from selectable drawing stencils over a reflection channel projected onto a recording medium and on this, with the assistance of a photochemical or photoelectric Converter or the like are made visible and fixed.

In order to increase the writing speed, but also to increase the considerable Reducing or completely avoiding the noise sources of conventional mechanical typewriters is already optical Writing works have been built. You work with a light source, with templates and optical systems through which light images pass have characters transferred to photosensitive writing pads.

In one known case, the drawing stencils are considered to be translucent Place arranged on a circular disk, which is at a constant speed between a light source and the recording medium rotates. A counting device ensures that a flash of light only occurs for a selected character if the template for the selected character is exactly between the writing point and the light source. .

Such an optical writing unit is complex and bulky. It not only needs the disc-shaped template carrier with constant Speed are driven, but there must also be provided elements that a friction shift between the rotating stencil disk and the photosensitive recording medium accomplish. Such devices make the arrangement more expensive and complicate, quite apart from that, is; it

difficult to accommodate a constantly rotating stencil disc in a typewriter of the usual spatial shape.

Also known is an optical writing mechanism with a cathode ray tube (character), which inside its bulb, towards the screen, has a template arrangement. The cathode ray is deflected onto the desired stencil and then displays the selected character on the screen.

The disadvantage is that the cathode ray tube through the built-in Stencil arrangement increases in price without this being able to achieve noticeable advantages with regard to the writing processes. The respective character must also be controlled by precision controls projected onto the desired writing position of the recording medium. The templates inside the piston can practically not be exchanged, so that you can only write with one and the same font.

The invention is based on the object of an optical writing unit to create a relatively high writing speed and almost noiseless operation with extremely simple means allowed. In addition, the writing should come with a the usual keyboard.

It has been found that these tasks can be accomplished in a simple manner through a system of optical lines and a multiple projector can be solved, by means of which each individual light image supplied using an individual optical image line can be projected onto the input of a flexible optical write line assigned jointly to all image lines, the output of which is so directed at the recording medium that this and the output of the flexible write line can be moved relative to one another are. .

Photo-chemical or photoelectric converters or the like in Connection with writing instruments, but especially with copiers, have long been known. They are not the subject of the present-

According to the invention, the output of the flexible optical writing line is in a writing projector, which is driven by drive elements Let a guide move back and forth ± 21 line direction.

JSs can be of advantage if only the relatively little hatred of the visual projector moves ZG relative to a stationary recording medium. needs to be. Without changing anything in the essence of the invention, however, the recording medium can also be moved relative to the writing projector, for example in the manner of normal typewriters.

To drive the writing projector is in an exemplary embodiment a stepping mechanism in connection with a return spring used. In another embodiment is a transport spindle provided on which the writing projector sits.

They are optical image lines with drawing templates and optical Switching or lighting elements in operative connection through each of which a picture line can be selected and the selected character within the multiple projector for the duration of an exposure period can be projected onto the input of the optical write line. .

In the simplest case, the drawing stencils either sit on the The outputs of the optical image lines introduced into the multiple projector, or on the inputs of these lines.

Such a writing unit is suitable for writing numerical values and the symbols used in pike machines. Here is the

909850/0318

Writing mechanism designed as simply as possible without being interchangeable the character types or switching from lower case to upper case letters must be taken into account.

In a preferred embodiment of the invention, the inputs of the optical image lines are in two rows with gaps one above the other, arranged. This arrangement enables the use of a stencil slide for the drawing stencils, which runs across the entrances of the optical image lines and can be shifted there by one template division for the purpose of switching.

¹ In order to enable writing with other fonts, the stencil slide is arranged interchangeably.

In a further embodiment of the invention, the drawing templates arranged on the circumference of a stencil cylinder, which lies transversely in front of the entrances of the optical image lines, and which lies around its longitudinal axis according to the stencil division is pivotable.

Both on the stencil pusher and on the stencil cylinder the drawing stencils are each double-rowed and dense, running in the same direction to the inputs of the optical image line arranged in such a way that in one position the lowercase letters and the like, in the position changed by a template division, however, the capital letters or the like in front of the inputs of the optical Image lines lie.

According to the invention, the switchover takes place only through an adjustment of the template carrier by one template division.

The drawing stencil cylinder has the advantage that the drawing stencils in several groups of zig-zaek double rows on his scope can be arranged. Each double row is assigned a specific font.

The required font is simply set by

BATH ORIGINAL

i that the corresponding drawing stencils' double row in front of the entrances the optical image lines is brought.

According to the invention, there is no need for one for each individual image line special light source to be available. Rather, the light source can be designed in the manner of a festoon and arranged in front of the drawing stencils.

The Light source arranged within this cylinder.

In both writing works, i.e. those with a stencil slider and those working in conjunction with a stencil cylinder are between the light source and each entrance of an optical image line each has a shutter slide and one that is common to all image lines and can be displaced transversely to these Arranged shutter slide.

The closing slide and the shutter slide ensure independently from the setting of the stencils, for the correct exposure.

For this purpose, each locking slide is provided with a locking opening equipped and connected to a corresponding character key,

The diaphragm slide has diaphragm openings which, in the rest position, are coaxial with the inputs of the optical image lines.

The shutter slide can be operated via drive elements with each character key come into operative connection, in such a way that each time after actuation of a shutter slide the shutter slide by "one template division is shifted sideways. This arrangement is made to ensure the correct exposure time for each character by pressing a key to obtain*

Once the shutter opening at the entrance of the selected B; L! Dleitung has been passed, the shutter slide is turned over

An advantage of the invention is that the multiple projector that optical image lines, the stencil carriers and the shutter and shutter slides can be arranged at any point in the housing of the writing mechanism.

However, it has been found to have significant advantages regarding the size of the writing as well as the simple ones Assembly and in terms of service, if the Optical image line inputs embedded in a shutter housing which also holds the shutter slide r and the shutter slide.

The diaphragm housing can preferably be made of plastic be.

If a template slide is used, it has attachment strips by means of which the stencil slide is held on the diaphragm housing.

In the simplest case, the panel housing is under the keyboard of the Written work arranged.

The new writing mechanism is equipped with a control display, for example, to make the respective keyed characters visible, which are connected to the multiple projector via a further image line is.

According to the invention, the flexible optical write line can be designed as an optical fiber line.
