DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image synthesizing printer, and more particularly to an image synthesizing printer most suitable for synthesizing an image of a photographic image and a character image.

[0002]

2. Description of the Related Art A conventional image synthesizing printer employs a character printing device equipped with a lithographic negative film to prepare a post card or a group photo in which a photographic image and characters, symbols, figures, etc. are mixed. And a CRT instead of using a lithographic film or a photographic image exposure unit and a line exposure unit for exposing characters and the like as shown in JP-A-1-291236. Was proposed.

[0003]

However, in the case of using a lithographic negative film, there is a problem that the preparation of the lithographic negative film is troublesome, the preparation time is long, and the equipment cost is high. Further, the one using the CRT has a problem that the efficiency is low. Further, in the image synthesizing printer disclosed in Japanese Patent Application Laid-Open No. 1-291236, there is a problem that when an illustration or the like is to be printed like a post card, a good print cannot be obtained.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an image synthesizing printer capable of performing high-quality exposure with high efficiency.

[0005]

In order to achieve the above object, an image synthesizing printer according to the present invention is proposed in which a light source light transmitted through a photographic film is stationary along a photosensitive material transfer path. A photographic image stationary surface exposure unit that projects and exposes the material, a stationary surface contact exposure unit that adheres another film to the stationary photosensitive material and exposes the photosensitive material in close contact, and is orthogonal to the transport direction of the photosensitive material Line-shaped PL provided in the direction
A PLZT line exposure section for line-exposing the photosensitive material being transported by the ZT head, and exposing using all three exposure sections;
At least one of the exposure units is arbitrarily selected, and exposure is performed using the selected exposure unit.

[0006]

According to the image synthesizing printer of the present invention, at least one of the photographic image stationary surface exposure unit, the stationary surface contact exposure unit, and the PLZT line exposure unit can be arbitrarily selected. Since the exposure is performed using the unit, favorable exposure corresponding to characters, illustrations, and the like can be performed.

Further, by exposing a photosensitive material using all three exposure units, that is, a photographic image stationary surface exposure unit, a stationary surface contact exposure unit, and a PLZT line exposure unit, efficient exposure can be achieved.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the image synthesizing printer of the present invention will be described below with reference to the drawings. Along the transfer path B of the photosensitive material A, toward the transfer of the photosensitive material, the photographic image stationary surface exposure unit 1
And a stationary surface contact exposure unit 2 and a PLZT line exposure unit 3 are arranged in this order. The photographic image stationary surface exposure unit 1 includes a photosensitive material A in which white light emitted from a white lamp 1a passes through a negative film 1b and is stationary on a first exposure stage 1c.
The photographic image A1 is printed on the photosensitive material A by forming an image on the photosensitive material A.

The stationary surface contact exposure unit 2 is configured such that the light emitted from the lamp 2a reaches the lithographic film 2b, and the image of the lithographic film 2b is adhered to the photosensitive material A and printed. Then, a photographic image A2 (illustration image of a toy in the drawing) such as a photographic image, characters, symbols, and figures is formed on the photosensitive material A by the stationary surface contact exposure unit 2.
Burned outside.

FIG. 3 is a view showing the lithographic negative film 2b. The hatched portions in the drawing show black light-opaque portions 21b. In addition, transparency (transparent film base for OHP) may be used instead of the lithographic film 2b.

The PLZT line exposure unit 3 is configured to perform line exposure on the photosensitive material A being transported by a linear PLZT head 31 provided in a direction orthogonal to the transport direction of the photosensitive material A. The PLZT head 31 is configured so that light is transmitted from a light source unit 32 via an optical fiber 33. The light source 32 is configured by disposing a heat absorbing filter 32b in front of a lamp 32a (FIG. 5). The PLZT head 31 includes an analyzer 31a and a PLZT
A crystal 31b and a polarizer 31c are stacked, and a selfoc lens eye 31e is provided on the analyzer 31a side (FIG. 5). A counter electrode (not shown) is mounted on the PLZT crystal 31b. L in FIG. 5 indicates the maximum width of the photosensitive material A.

The driving of the PLZT head 31 is linked with the driving of the photosensitive material transfer motor M, so that good characters, figures, and the like are always exposed. Also,
Since the loop of the photosensitive material A is interposed between the stationary surface contact exposure unit 2 and the PLZT line exposure unit 3, exposure can be performed asynchronously with the static surface contact exposure unit 2.

One or two of these three exposure units 1, 2, 3 can be arbitrarily selected, and the photosensitive material A can be exposed using the selected exposure unit. Further, it is configured such that the photosensitive material A can be exposed using all the exposure units 1, 2, and 3.

A loop is formed in the transfer path B between the photographic image static surface exposure unit 1 and the static surface contact exposure unit 2 by curving the photosensitive material A exposed by the photographic image static surface exposure unit 1. A first loop forming stage 4 is provided, and the presence of the first loop forming stage 4 allows the photographic image stationary surface exposure unit 1 and the stationary surface contact exposure unit 2 to perform asynchronous exposure. I have.

In the transfer path B between the stationary surface contact exposure unit 2 and the PLZT line exposure unit 3, there is formed a loop for forming a loop by curving the photosensitive material A that has been subjected to the contact exposure in the stationary surface contact exposure unit 2. A two-loop forming stage 4a is provided. 5
Is a magazine, and in this magazine 5, photosensitive material A
Is wound in a roll.

Reference numerals 6, 7, and 8 denote conveying rollers for conveying the photosensitive material A along the transfer path B. Reference numeral 9 denotes a developing section, which is a photosensitive material A developed by the developing section 9.
Are cut one by one by a cutter (not shown) and collected on a tray 10.

Next, the operation of performing overlapping exposure by the image synthesizing printer will be described. First, the photosensitive material A is led out of the magazine 5 by the transport roller 6. Next, the photosensitive material A is set on the first exposure stage 1c of the photographic image stationary surface exposure unit 1 and is stopped, and the photographic image A1 is printed as in the conventional photographic printer (FIG. 2). Next, in the first loop forming stage 4, the photosensitive material A is curved to form a loop. Next, the photosensitive material A is set on the second exposure stage of the stationary surface contact exposure unit 2 and is stopped, and the photographic image A2 is printed by contact exposure (FIG. 2). Next, the photosensitive material A is curved at the second loop forming stage 4a to form a loop. Next, in the PLZT line exposure unit 3, while driving the photosensitive material transfer motor M to transfer the photosensitive material A,
The photographic image A3 is line-exposed on the photosensitive material A by the PLZT head 31 (FIG. 6). After the photosensitive material A that has been repeatedly exposed in this manner is developed by the developing section 9, the photosensitive material A is cut into individual frames by a cutter and collected on a tray 10.

[0018]

As is apparent from the above description, according to the image synthesizing printer of the present invention, one of the photographic image stationary surface exposure unit, the stationary surface contact exposure unit, and the PLZT line exposure unit is used.
One or two exposure units can be arbitrarily selected and exposure can be performed using these exposure units, so that efficient exposure can be performed.

Exposure of the photosensitive material using all three exposure units, ie, the photographic image stationary surface exposure unit, the stationary surface contact exposure unit, and the PLZT line exposure unit, enables efficient exposure.
