The present invention relates to a photographic magnet.

In recent years, the development of photomagnetism has become more dominant by electronicization, and a lot of research has been conducted accordingly.

For example, when a lens having an arbitrary magnification is installed in the photographing optical device, the magnification is detected and conveyed to the outer feeding device, thereby automatically setting the feed amount corresponding to that magnification. Therefore, the setting of the feed amount for carrying out the front feed accompanying the lens conversion is almost unnecessary, which greatly improves the work efficiency.

However, this method is only to link the magnification of the lens and the transfer device, and it is not considered in the lens type. The type of the lens refers to a type in which the lens is mounted on a swivel table. Explain.

In Fig. 1 (a), the rectangular frame of (1a) to (1f) indicates the size of characters when printed in the vertical direction by the predetermined magnification of the lens, and the center 2 is a frame of any size. It is an example of a vertical combination that is also consistent with each other. When (1a) to (1f) are printed at the same position, the centers (2) and (3) in the X and Y directions coincide with each other as shown in (B). This is because the lens is installed on the swivel table so that the center of the lens is more aligned. Such a type is called a center and a center type (hereinafter referred to as CC type).

In the machine equipped with the CC type lens, even if the lens is printed using any magnification, the center is printed regardless of the combination of vertical and horizontal. There is an advantage.

However, in such a case, the work which becomes troublesome in conversion of a feed amount is calculated | required. If this is demonstrated by FIG. 1 (c) and FIG. 1 (d), when printing the frame 1C by a certain magnification, the movement 4 corresponded to that magnification will be automatically performed, and then it will be exposed. Will be However, after moving (4) as shown in (D), if the magnification is changed from (1c) to (1a), an extra space of (L ₁ ) is generated. When the 1a is exposed, the transfer corresponding to the 1a is performed. When the magnification is further converted at that time, the frame of the 1a and the 1C overlaps.

Therefore, when the CC format, since the embodiment without any connection with the lens type (Q ₁ / Q 2 + _2/2) should not be if you do not correct the amount of the (where Q is the magnification of the lens) each time.

And another unreasonable point is explained by FIG. 2, and FIG. 2a is an example in which 9 characters are printed between the coordinates of (X ₁ ) and (X ₂ ). In this case, first install the lens of the required magnification by using the given coordinate (X ₁ ) as the printing start position. Then, since the lens is of CC type, (X ₁ ) coincides with the lens center (originating position at the time of transfer) as shown in (B). Therefore, a 1/2 (L ₂ in the figure) to the transport direction, that is, In this case, because the combination of the horizontal home position by moving in the right direction (L ₂₎ (print starting position) of a feed amount corresponding to the magnification again You must set it.

The same thing happens at the end of the incense. In FIG. 2, when the character 5 is printed at an arbitrary magnification, the distance to the coordinate X ₂ at the end of the line must be originally determined as (L ₃ ). However, in the CC format, since the origin is based on the center as described above, up to (X ₂ ) as (D) is determined as (L ₄ ), and the character 6 represented by a dotted line is printed.

In order to solve such a problem, a form as shown in FIG. 3 (A ') is also required, and an end-to-end form such as (C) or (D) (hereinafter referred to as TT form) is also required.

Therefore, the coordinates of the head of the row and the end of the row (hereinafter referred to as the factor area) are defined as (X ₁ ) (Y ₁ ), (X ₂ ) (Y ₁ ), (X ₁ ) (Y ₂ ), (X ₂₎ (Y ₂₎ when the virtual hayeoteul that, (a), (a ' ), (B), (B'), (C), (C '), (D), (D') and Fig. 1 Nine forms of CC type described in the following are required. If a swivel with the nine types of lenses is installed, that is, nine swivel lenses in one machine, it can cope with any case. However, it is clear that this method is not practical. Therefore, although the magnification of the lens and the transfer device are interlocked with the conventional machine, the lens type cannot be coped with, and according to the required lens type, (L ₁ ) and (L ₁ ) described in FIG. ₂ ) or (L ₄ ) was usually performed manually each time. In the above description, the conversion is made to the TC format (mixing of the CC format and the TT format) or the TT format based on the CC format of FIG. 1, and when converting to the CC format or the like based on the TC format, Of course it is.

The present invention has been made in view of such a point, and provides a photographic magnet with an automatic conversion function of a lens type in a machine in which the magnification of the lens and the conveying device are in communication. In order to be able to freely convert the nine types described by one machine and to improve the efficiency of printing by linkage with a conveying device, in order to achieve the above object, the present invention is applied to the set lens magnification. In response to the photographic apparatus for setting the transfer amount to the transfer apparatus, a button group for instructing the transfer direction and the conversion of the lens type, a storage unit for storing the instruction contents from the button group, and a magnification and storage unit for the set lens A control device that selects the desired lens type according to the contents and calculates 1/2 of one transfer amount by the magnification of the lens; Value to the changed position in the transport direction by the calculated value to the new origin position by operating the transport device is characterized in that it includes a transfer control circuit for changing the relative position of the optical device gamjae.

First, the principle of the present invention will be described.

In Fig. 3, (A) and (A '), (B) and (B'), (C) and (C '), (D) and (D') are only different transfer directions (arrows). In other words, it can be of the same type if only its conveying direction is supported. In this way, the forms of (C) and (D) can be the same.

Thinking in this way, three types of CC, TC, and TT can be considered, as shown in Figure 4. Therefore, in the present invention,

(1) Indication of the conveying direction

(2) Conversion instruction of lens type (CC, TC, TT)

(3) Instruction of lens magnification

Is given to the machine to set a predetermined lens type, and transfer by the lens type is possible.

That is, one of the nine lens types is selected based on the conversion instruction of the lens type and the information on the transfer direction, and then the origin position is shifted by 1/2 of the transfer amount corresponding to the magnification of the lens according to the selected lens type. Move to the new reference point.

In this way, when converted to a new lens type, after that, when the transfer starts from the designated printing area coordinate with the new reference point as the origin, printing can be performed in a predetermined lens format. In the case of the TT type, the shift amount of the aforementioned half is shifted in both directions, at right angles to the conveying direction and at 90 degrees (that is, in the X and Y directions), which becomes evident in FIGS. 3C and 3D. In the present invention, even in the case of such a TT type, please pay attention to the expression "conveying direction").

Next, an embodiment of the present invention will be described with reference to FIG. 5, wherein reference numeral 11 denotes a light source, 12 denotes a condenser lens, 13 denotes a prism or a mirror, and 14 denotes a letter plate containing various character symbols. (15) is a rotating frame where lenses of various magnifications are provided, (16) is a deformable lens installed according to need, (17) is a prism or a mirror, (18) is a shutter, and (19) is a lens A conveying apparatus which prints letters and the like on the damping material on the drum 21 while moving to a drive source 20 such as a pulse motor for transverse conveying by installing a prism, (22) a damping drum, (21 ) Is a drive source such as a pulse motor for vertical transfer to rotate, 23 is a control unit, 24 is a drive control circuit for giving a command to the drive source 20, 22, 25 is a drive source 20, The present position counter which receives a signal from (22) and calculates the present position of the transfer device 19 and the damping drum 21, (26) receives signals from each block and An arithmetic operation unit 27 is a storage unit that stores contents input from various input buttons, 28 is a button for inputting coordinates of the printing area described in FIG. 3, 929 is a vertical combination and a horizontal combination command. (30) is a button for instructing the feed direction of the magnetic gear, and (31) is a button for instructing the conversion of the lens type. In the drawing, the TC type and the TT type are commanded (that is, the rotary table 15). Lens type is CC). The control unit 23 and the calculation unit 26 are collectively called a control device.

Now, in order to obtain a printout such as FIG. 2 (a), first, the coordinates of (X ₁ ) and (X ₂ ) of FIG. ₂ are inputted from the coordinate input button 28 of FIG. Remember to.

Next, in such a case, since it is a combination of horizontal, the meaning is commanded with the button 29. FIG. In this way, the left-right command is commanded by the button 30 which commands the conveyance direction, and the TC-type command is commanded by the type command button 31. On the other hand, the magnification of the predetermined lens in the lens swivel 15 is detected by a detection means (not shown), or a predetermined lens is installed in the optical device by the use of a lens selection button, and the magnification signal is supplied to the control unit 23. The storage unit 27 stores the command signal together with the command signals from the various buttons 28 and 31 described above. The contents of the storage unit 27 are sent to the calculating unit 26 to select the lens types (A)-(D ') in FIG.

In that case, the conveying direction is from left to right in TC type, so the control device selects the lens type in Fig. 3A. In addition, in the magnification information of the lens, the calculating unit 26 divides the transfer amount corresponding to the magnification into two, and pushes the TC corresponding to the transfer direction by that value, that is, at the reference point A of the CC type in FIG. The position changed into the reference point B is sent to the storage unit 27 for storage as the reference point. In this way, the CC format is converted into the TC format. Now, the transfer device 19 is stopped when there is a second degree coordinates (X _1), the current position counter 25 has its value is sent to the arithmetic unit 26. The Then, the operation unit selects the difference between the value of the current position and the point (B) according to the TC type stored in the storage unit first and sends it to the transfer control circuit 24. That is, from the point (A) to the point (B). As the reference point changes, the difference from the present position counter becomes 1/2 of the conveying amount 1 by the magnification.

When the value is transmitted, the control unit also sends a command to the transfer control circuit to move the transfer apparatus so that the transfer apparatus 19 moves by the difference. If the current position counter 25 determines that the distance corresponding to half of the feed amount corresponding to the magnification of the lens has been moved, the movement amount due to the conversion of the lens type also matches, so that the control unit releases a command to the feed control circuit.

In this way, when the printing start position is changed and the lens of the CC format is converted to the TC format and the preparation of the printing is completed, the printing buttons and the like not shown are operated to start the printing of the first character. First, the necessary letters are found in the letter (4) and installed at the optical axis position of the optical device, and the shutter 18 is operated to expose the first letter to the material on the damping drum 21. Then, the drive source 20 is operated by a distance corresponding to the magnification of the lens in which the feed control circuit is installed to install the feed device 19 at the position of the second character.

After that, if the present position counter 25 is matched with the value of the (X ₂ ) coordinate stored in the storage unit 27, the control unit 23 changes the row to the head position of two rows, Prepare for line print behavior. In this manner, when the printing operation is completed, the printing material as shown in FIG. 2 (a) is obtained.

The above description can be treated as such, even if not located in, (X ₁₎ of the coordinates, but when the transfer device 19 is stopped and the (X ₁₎ coordinates. Therefore, for example, if you switch TC and TT regardless of the heading (X ₁ ) and the end of the line (X ₂ ), you can simply do it without correcting the front feed when mixing characters of different sizes such as 1st and 6th. It becomes possible.

When it is other than the form of Fig. 3 (a), it can be treated as such at all. For example, in the case of (A '), the conveying direction is changed from right to left, and in (B), up → down, (B In the form of '), it is simply changed from bottom to top.

Also, in the form of (C), (C '), or (D), (D'), the change of the reference position is changed by 1/2 of the feed amount corresponding to the magnification of the lens to change the format. It is already mentioned above that it is good to make it to a direction, and even if it pushes in 1/2 in a "conveying direction" even in such a case.

In addition, the machine shown in FIG. 5 is one embodiment and can be variously changed, such as the shape of an optical device, the method of changing the relative position of a sensing material, and an optical device, and the kind of light source.

As described above, the present invention instructs the conversion of the lens magnification, the conveying direction, and the lens type, respectively, first to select the desired lens type, and then to correspond to the original position (lens magnification 1/2) according to the selected lens type. It is to provide a photographic porcelain which changes only the part in response to the conveying direction and changes the relative position of the sensing material and the optical device based on the changed origin position. This solves the problem of the conventional lens type and the transfer device without increasing the number of lenses, and it is possible to immediately start printing at the coordinate of the designated printing area and to end it at the designated coordinate. When mixing letterheads that match the headings as shown in (a) or characters of different sizes, as shown in Figure 6 (b), avoid the proportions and lens-type complexity of the headings that match the headings, and simply specify The effect is great because it can be obtained efficiently.
