Description

however, with this additional facility

35 device for shifting the image location has not been eliminated. The well-known facility is already there for this

The invention relates to a photocomposition machine which is unsuitable because it is suitable for larger clubs Character matrix, a character selection device, shifts for index and exponent formation and a character projection device as well as directed, and not to the very minor Corrections two lenses in rows perpendicular to each other, which are required for the quality set. the Settings in one adjustable stop each perpendicular to the projection axis allow even a too large toIe plane fear of being able to move around by means of a drive device in order to be able to reliably correct errors, which enable one to get the information about the character correction. Above all, would have to be with analog selection contained punched tape is controllable. Application of the error to be compensated in the

In known phototypesetting machines, the individual punched strips, in addition to the information, are each time punched in a matrix-like arrangement on a plate for character selection. When the and the known additional devices are moved or rotated to their original disk in the range which the imaging of the purpose should fulfill the optical elements effecting the setting of indices and expo selected characters with different font size settings. In other photocomposing machines, the 50 would have to be permanently arranged in the plate carrying the additional information in the perforated tape matrix, and the output is formed by a special arithmetic operation Elements. In both cases it is necessary to include a shift in the components. The means to ensure that the selected characters are precisely touched by these values in the punched tape were designed with regard to the imaging optical elements through even more complicated than they are directed to solve anyway, so that the images are each of the known task, since this is the case Additional keypad selected characters in the precisely prescribed doors that appear in connection with the main keypad in connection with the target position on the image level. Go yourself, are required. It therefore appears that despite slight deviations from the target positions, there are difficulties that lead to easier quality typesetting through an uneven and unsightly scriptural comparison and exact production of the script image. To ensure lateral deviations from the target position stitch matrix than the additional deviations provided for setting not so much as vertical deviations in terms of indices and exponents, plus the line line. It is difficult to get the required facility

However, the inaccuracies in this setting must be used for exact alignment of the selected character are compensated * this compensation is only part of the task of present invention

The invention is based on the object of achieving as uniform a typeface as possible for the quality typesetting with great effort, although the characters to be mapped are not exactly positioned on their matrix and although the character selection device is subject to setting errors. The light setting machine should be as simple as possible

This task is given by the one specified in claim 1 Invention solved. This is done by an integrating lever system with several pull magnets unu diving anchors made use of which are known to be used for character selection.

This has the essential advantage that at in the manufacture of the character matrix and in the Baj of the character selector, none excessively high demands on the accuracy are to be made, although these parts are used high quality set is to be generated. With the drive device of the lenses can be the integrating lever system with several pull magnets with plunger armature all necessary compensation values set digitally in steps. These levels are much lower than the character selection levels or to shift characters for exponent or index formation. For each Characters, the compensation value is determined once when the machine is calibrated. Thereafter the logic circuit is dimensioned so that a combination corresponding to the compensation value the pull magnet is excited when the logic circuit with the information for character selection is applied. The information for character selection in the punched tape is therefore not used only for character selection, but also causes the signals with which position errors are automatically corrected will. The punched tape perforator for controlling the photocomposing machine remains unchanged. The operator can operate this perforator in the usual way, i. H. no additional Information to be punched.

The invention will then be explained in more detail with reference to the figures. It shows

F i g. 1 is a schematic representation of an arrangement for selecting characters in a Photocomposing machine. It consists of a light source 11, a condenser lens 12, a character matrix 13, .to a collimator lens 14, character selection keys 13 and a film 17. With the aid of the condenser lens 12, the light emanating from the light source 11 becomes evenly distributed over the matrix 13. The the individual Light beams penetrating character areas are in the collimator lens 14 in parallel light bundles converted. The wedge assembly 15 oesteM from pairs of chunks with different apex angles, which are shifted and / or rotated in this way can be that the matrix is optically scanned and the individual characters by deflecting the light bundle emerging from the collimator lens can be selected. In the arrangement according to FIG. 1, there are only two pairs for the sake of simplicity Wedges are shown, but more such pairs of wedges are used to scan the entire matrix. After the light beam penetrating the desired character has passed through the wedges is, it penetrates the sieve aperture 16 (the alIe other light beam suppressed) and falls as soon as a lock, not shown, is operated aut the film 17. As in a character selection arrangement having a large number of characters Matrix requires a large number of optical wedges, the summation of each can be by itself small deviations from the prescribed Stir in the refraction angles of the individual wedges, that the images of individual characters are relatively strongly deflected from the target position. Furthermore the wedges come in a wide variety of combinations used to select the individual characters, so that the individual deviations can be summed up resulting total shift will be different for different characters. Falls a light beam penetrating a lens onto a point that is different from the target position, see above the light beam can be brought into its desired position by placing the lens in the desired position Direction and shifted by the desired amount. It is therefore possible to postpone the so imaging a character through a pair of corrective lenses balance. As indicated in Fig. 1 with broken lines, a correction nose 32 in horizontal direction to correct horizontal deviations and a second corrector rase 22 in 55 arranged displaceably in the vertical direction for correcting vertical image deviations. Any lens can be shifted by a large number of discrete amounts in order to compensate for deviations of different sizes.

Correction values are entered into the machine so that, in order to allow for different lens deflections, the correction lenses act correctly for each character. For this purpose the pull magnets 37 are to be placed. This has the consequence that at the same time and 38 by means of the pins 40 and 41 with a lever with the selection of a character one for this line 39 is connected. This lever is connected to a lever 42 by means of the necessary adjustment of the correction lenses 5 43. The pulling magnet takes place so that the image of the selected character in 44 and 45 are in the same way by means of the pins 47 its desired position falls on the plane of the film. Connected to others and 48 to a lever 46. The lever 46 words means that when a character signal is read by means of the screw SO with the lever 49 projecting a certain character. The output member 34 is by means of which this signal is used simultaneously for the displacement and adjustment of the screw 51 with the lever 42 and by means of the position of the correction lenses, so that the screw 52 is connected to the lever 49,

This distance is equal to plane. This shift takes place, 0.25 mm. The lever 34 is through the screw 51 when all pull magnets are energized. The spring 27 is connected to the lever 42 so that it turns around which leads the lens holder back to its rest position, so screw 52 rotates.
