BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for displaying a monitor in a photographic magnet using an optical dial as a source of character generation, and in particular, enables the result to be checked externally during printing during the printing state on the photosensitive material.

In a photographic writer using an optical dial, which is generally called a manual device, as a source of text generation, it is difficult in principle to directly grasp the printing state on the photosensitive material during printing, and it is convenient if the printing state can be easily confirmed. Needless to say, especially in the so-called mixing factor or honeydew factor that prints characters of different sizes, or the filling factor that fills the space of the letter appropriately depending on the shape of the letter, Sensational impression received was important, and grasping of progress in printing was required even in the sense of being able to judge the texture during printing.

As a conventional method of displaying a monitor of a photographic magnetic device studied under such a request, for example, branching a character image printed through a half-milter or the like inserted into a projection factor optical system and displaying it on a fine tea, or It is known to display the characters already printed and the characters printed next in sequence or in a column at a predetermined size at a predetermined constant position on the cathode ray display tube.

However, the former of such a conventional method projects a character image on a finder made of translucent glass or the like, so that the character image displayed thereon is transient, and thus has no relation with the character already printed. In addition, the latter display method simply knows the type of characters (what type of characters) and the image of each character is not known at all in the actual printing position, size and shape on the photosensitive material. Even when printing at an undetermined position, it was displayed in a series of fixed positions sequentially according to the order of the factors, so that there was a risk of causing an incorrect operation.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and a monitor display that enables the user to easily check the actual printing state on the photosensitive material for the character to be printed or various characters already printed from now on. It aims to provide a method.

It demonstrates with drawing below.

1 is a schematic diagram showing an example of the apparatus according to the present invention. In Fig. 1, reference numerals 1-17 are well-known parts for constructing a photographic magnet of a type in which an optical dial is used as a character generating source. In brief description of this, light from the light source 1 is a condensing lens 2. Through the prism 3 and the prism 3 to selectively irradiate the characters on the optical dial 4 and transmit the luminous flux from the irradiated characters to the variable lens 5, the modified lens 6, the prism 7 and the shutter ( 8) Projected on the photosensitive material drum 10 through the projection factor optical system such as the moving optical system 9, and the desired character image on the photosensitive material 11 loaded on the drum 10 is projected. Reference numeral 12 denotes a driving solution attached to the moving optical system, and 13 and 14 move the printing position on the photosensitive material by driving the moving optical system 9 and the photosensitive drum. 15 is a drive source for selecting the desired shift lens 5 and the deformable lens 6 and positioning them in the projection factor optical system, and 16 is a pull of the selected signal of the desired lens with the drive source 15 described above. (17) is a transfer control circuit for operating the drive sources 13 and 14 described above in accordance with a desired print position signal commanded from a circuit not shown separately.

In Fig. 1, reference numeral 18 denotes a monitor image pickup section inserted into the projection factor optical system to obtain an image signal of an image proportional to the size of the image to be printed. For example, half Milter 19 The monitor optical system made of the imaging lens 20, the imaging tube 21, the read control circuit 22 of the imaging tube, and the like.

Reference numeral 23 denotes a printing position signal setting unit for outputting a signal corresponding to a desired printing position on the photosensitive member 11, that is, a relative position of the projection factor optical system with respect to the photosensitive member 11, for example, The X position register 24 and the Y position register 25 which advance in accordance with the operation of one drive source 13 and 14 are provided. Reference numeral 26 is a read address signal generator that outputs a read address signal required for scanning the image of the image projected on the imaging tube 21 described above. Numeral 27 denotes a display control circuit for driving control of the display means 28, which includes a suitable display means 28, such as a cathode ray tube display tube (CRT) storage type display tube or a plasma display, and a refresh demonstration as required. A monitor display section (29) or the like, which receives the image signal from the monitor image pickup section 18 and outputs the address signal and the print position described above from the read address signal generation section 26; A character image desired to be received as a display (or writing) address signal of the desired factor position signal output from the signal setting section 23 is displayed at a predetermined position on the display means 28.

In the case of employing the non-accumulated cathode ray display tube (CRT) described above as the display means 28, the control of writing to the refresh memory is controlled in the case of the present invention. Since it is basically the same as control, the following description demonstrates the case where an accumulation type display tube is used as the display means 28. As shown in FIG. In addition, when the image pickup signal is read by the monitor image pickup unit 18, the above-described signal from the read address signal generation unit 26 may be converted into an analog signal to directly drive the image pickup tube 21. Alternatively, in order to facilitate the operation and synchronization of the monitor display unit 27 described above, an image memory may be provided in the read control circuit 22 of the imaging tube so as to read a desired signal from the memory.

FIG. 2 is a diagram showing the relationship of each signal in the embodiment shown in FIG. FIG. 3 is a view showing the coordinates of the current printing position A on the photosensitive material 11, and an example of the characters (letters " 점 " indicated by dotted lines) for printing from now on. FIG. Fig. 5 shows an example of the character being projected on the image, i.e., the character selected from the optical dial 4 for printing (from now on, the letter “ぁ” indicated by the solid line), and FIG. 5 shows the display on the display means 28. It is a figure which illustrates the state.

In the following, in order to simplify the description, the scales on the photosensitive material 11 and the image pickup tube 21 and the display means 28 shown in FIGS. 3 to 5 are the same.

Here, for example, as shown in FIG. 3, when printing the character “ぁ” with the coordinate Xa Ya on the photosensitive material 11 as the desired printing position A, the printing position as described above The signal setting section 23 is connected to the photosensitive material 11 when the desired factor position signal (the feed control circuit 17 and the print position signal setting section 23 are interlocked with each other as shown in FIG. 1). Since the signal following the current position of the projection factor optical system) is output, signals corresponding to Xa and Ya are respectively output to the lines 30 and 31 of FIG. 1, and to the imaging tube 21. The letter “ぁ” is projected as shown in FIG. In addition, in the configuration of FIG. 1, when the current position of the projection factor engineering system moves to the point (B) of FIG. 3, signals corresponding to (Xb) and (Yb) are output to the lines 30 and 31 described above. In FIG. 2, the former case is indicated by (A) and the latter case by (B).

The read control circuit 22 of the image capturing tube is configured to read the horizontal and vertical address signals ΔX and ΔY through the lines 32 and 33 as shown in FIG. By receiving from 26, the image signal IS projected on the image pickup tube 21 is output to the display unit 27 via the line 34. FIG. The above-described address signals ΔX and ΔY are transmitted through the lines 30 and 31 in the addition circuits 36 and 37 of the address signal generator 35 for display (writing). The signal is added to the desired factor position signals Xa and Ya and the inclusion signal is supplied to the monitor display unit 27 as the display (write) address signals Xd and Yd shown in FIG. The display control circuit 29 in the monitor display section 27 operates in accordance with the above-described image signal IS and display (write) address signals Xd and Yd to drive the display means 28 described above. Thus, on the display means 28, for example, as shown in FIG. 5, a character identical to the character projected on the imaging tube 21 corresponds to a desired printing position A in the photosensitive member 11, where A 'is the same. Will appear on the screen. In addition, when the display control circuit 29 is provided with a refresh memory as in the past and drives a non-accumulated cathode ray display tube, it is of course possible to write the display as described above in the refresh memory.

In addition, when the printing position of the projection factor optical system with respect to the photosensitive material is in the point (B) of FIG. 3, the (B ') point corresponding to the said (B) point on the display means 28 is referenced. It goes without saying that the desired character is indicated in one area 38.

As described above, the character image displayed on the display means 28 is displayed at the position corresponding to the printing position of the projection factor optical system with respect to the photosensitive material 11, and is printed in the same state as the size and shape of the character to be printed. In the case where the printing operation is carried out in such order as the order under such conditions, the display state on the display means 28 faithfully reproduces the printing state on the photosensitive material, so that the printing state can be directly detected during the printing operation. You will get a big effect. 6 is a schematic view showing another embodiment of the present invention, in which the monitor image pickup unit 18 is provided between the optical dial 4 and the variable-length lens 5 and the size of the printing characters (typically the size of the characters). The number information setting unit 61 is newly installed in the embodiment of FIG. 1, and the operation of the display (signal) address signal generation unit 35 for display (writing) is related. Some are different.

The Q number information setting unit 61 receives and sets, for example, Q number information corresponding to the variable displacement lens 5 inserted into the projection factor optical system from the lens selection circuit 16, and The information Q is output via the line 62. In the embodiment of Fig. 6, since the monitor image pickup section 18 is provided on the dial 4 side rather than the variable speed lens 5, the type of the variable speed lens 5 is irrelevant. In other words, irrespective of the size of the character image projected onto the photosensitive material, the character image of a constant size is always projected onto the image pickup tube 21, and in that respect, it is greatly different from the case of the embodiment of FIG.

The proportional circuit 63 provided in the above-described display (signal) address signal generator 35 is supplied to the read control circuit 22 of the image pickup tube via the lines 32 and 33, and the address signal [Delta] X is provided. The addition circuits 36, (same as (ΔY)) and the address signals (ΔX ') and (ΔY') whose amplitude is proportional to the value Q (i.e., the magnitude of the print character) of the Q number information. 37).

Therefore, the state of the character obtained in writing and displaying in accordance with the above-described address signals ΔX 'and ΔY' is the number of Q corresponding to each of the seventh (a) and seventh (b). Is a character image of a size proportional to the values Q1 and Q2 (i.e., equal to the size of the projection character image on the photosensitive material).

The electrical address signals ΔX ′ and ΔY ′ output from the proportional circuit 63 are added to the signals in the print position signal setting section 23 in the addition circuits 36 and 37. The sum signal is supplied to the monitor display unit 27 as an address signal Xd '(Yd') for display (writing).

Therefore, in the configuration of FIG. 6, for example, as shown in FIG. 8, the position C having the coordinates Xc and Yc on the photosensitive material 11 is the projection factor position of the optical system, and the letter having the size of Q1 is " In the case of printing "k", a character image like the seventh (a) is displayed on the display means 28 at the position C 'corresponding to the above-described printing position C as shown in FIG. In the case where the printing position is at the point (D), the desired character image is displayed on the basis of the point (D ') corresponding to the position (D), so that the display exactly the same as the printing state is displayed on the display means (28). Will be obtained.

Thus, in the case of FIG. 6, even when the monitor image pickup unit is provided on the front face of the variable-resolution lens 5 and the size of the image projected on the monitor image pickup unit and the size of the image actually printed is different, the same display as the printing state is always displayed. To be obtained.

Incidentally, the configuration of the display address generator 35 for display (write) shown in FIG. 6 is merely one example, and the present invention is not limited thereto. In other words, the read address signal supplied to the monitor imaging unit 18 is described. When (ΔX) (ΔY) and the desired factor position signal are added, the display address signal Xd '(Yd') whose display amplitude is proportional to the Q number information Q can be obtained. Of course you can.

Further, in the above description relating to FIG. 6, there is no mention of the case where the image is deformed by the deformable lens 6, but in this case, the deformed character signal generation circuit, which is well known, is referred to as the proportional circuit described above. By appropriately inserting the lens on the front or rear surface of 63), the modified lens information is also added to the Q number information setting unit 61 to cope with the problem.

1 and 6 show an embodiment to which the present invention is applied. For example, the moving optical system 9 is abolished so that the photosensitive material drum 10 can be moved laterally. It is possible to employ various configurations without changing the gist of the present invention, such as allowing the monitor imaging unit 18 to enter or exit the projection printing optical system or making the imaging tube 21 a solid-state imaging device. Do.

In addition, if a suitable image memory is provided in the read control circuit 22 of the image capturing tube, the character image projected on the image capturing tube 21 is once stored in the image memory and the appropriate image signal is read out. Even when there is a defect in the character displayed on the image, it is possible to reliably incinerate only the memory and display relating to the defective character in accordance with the signal in the image memory. Therefore, if only the memory and the display relating to the defective character are erased as described above, then the desired factor position is slightly displaced and the monitor display operation as described above is performed again, the display of the already printed character is fixed. It is now possible to move and display the character to be printed at any desired position. Of course, the characters already printed at this time are fixed in the accumulation display tube or the refresh memory and do not change. Therefore, according to the present invention, the position and size of the character to be printed next can be designed by looking at the positions and relations (layouts) of these printed characters and the character to be printed from now on.

In addition, the operation of the feed control circuit 17 and the print position signal setting section 23 in FIG. 1 is removed, so that the desired print position signal from the outside is set in the registers 24 and 25, which have been transmitted from the outside. As a result, it is, of course, possible to display the character image picked up by the monitor image pickup unit 18 described above at a desired printing position set from the outside.

As described in detail above, the present invention selects a desired letter from the optical letter board and directs the letter to the photosensitive agent through a projection factor optical system having a variable lens; Projected onto the monitor image pickup section inserted between the ashes: read image signals corresponding to the projected characters in accordance with the read address signals, and read the read image signals on the read address signals and on the photosensitive material. A signal corresponding to the sum signal of the desired printing position signal of the signal is supplied to the monitor display section as a display (writing) address signal: the character image selected from the above optical character plates is stored in the monitor display section in correspondence with the desired factor position. So that the printout of the printout on the photoresist Prevention of wasteful operations to view the working factor involved in typo (誤 植), improvement of operation, it will contribute to the sensory factors such as the execution of the overall design of the ray outro.
