2. Description of the Related Art A printer processor is called a minilab and is installed in a DPE store or the like. This printer processor has a printer unit that prints and exposes an image recorded on a negative film onto photographic paper, and a processor unit that develops the photographic paper that has been subjected to the print-exposure process. The printer can be automatically conveyed and processed in the printer unit and the processor unit only by setting the printer in the printer processor. In the printer section of this printer processor, the image on the negative film is enlarged to a selected fixed size and printed on the photographic paper, and the photographic paper on which the image is printed is sequentially conveyed to the processor section. Developed and finished as a photographic print.

By the way, in printing and exposing photographic paper in the printer processor, the photographic paper is conveyed to a position facing an exposure mask device for printing and exposing, and then the photographic paper is properly fixed at this position. A paper mask was required to do so, and the paper mask was loaded into the mask device.

However, when the printing paper is conveyed, the leading end of the printing paper is curved like a gutter, and the leading end of the printing paper hits the paper mask itself or the end portion of the opening provided in the paper mask to properly position the printing paper. There was a risk that they could not do it.

Therefore, it is necessary to close the mask device, for example, so as not to hit the paper mask itself or the end of the opening of the paper mask when the photographic printing paper is conveyed. Therefore, as disclosed in Japanese Utility Model Laid-Open No. 63-43138, it has been considered to insert a loading blind plate that covers the opening into the mask device. However, when the loading blind plate is used, it is necessary to mount and remove the loading blind plate each time the printing paper is conveyed, which has a drawback that the work becomes complicated.

The operation of the mask device of the photographic printer according to claim 1 will be described below.

A frame is mounted facing a conveyance path for conveying the photosensitive material of a photographic printer for printing and exposing the image on the negative film on the photosensitive material. A paper mask is held by a holding member that is supported by a frame so as to be linearly movable toward the conveyance path of the photosensitive material, and the paper mask is moved together with the holding member to the side of the photosensitive material on the conveyance path by a driving source, and the photosensitive material is moved. To position the photosensitive material.

Therefore, since the paper mask can be linearly moved in the direction orthogonal to the photosensitive material with the linear movement of the holding member, when the photosensitive material is conveyed,
Unlike the case of rotating the paper mask or letting it escape,
Since the whole paper mask has escaped greatly,
When the photosensitive material is conveyed, there is no risk of the photosensitive material coming into contact with the paper mask, and the loading blind plate is no longer necessary.

The operation of the mask device of the photographic printer according to claim 2 will be described below. Claim 1 also according to this claim
However, the present invention uses a motor instead of a drive source, and the power transmission mechanism converts the drive rotation of this motor, which can be driven and rotated, into a linear motion to move the holding member to the photosensitive material side. It is supposed to do.

Therefore, since the motor is used as the drive source, it is not necessary to use a drive source such as a solenoid in spite of the linear movement of the paper mask, and noise is generated as in the case of using a solenoid or the like. Disappears.

The operation of the mask device of the photographic printer according to claim 3 will be described below. Claim 1 also according to this claim

The details of the mask device 64 according to this embodiment will be described below. As shown in FIGS. 2 and 3, a bracket 116 is attached to the right side portion of the frame body 112 that constitutes the main body of the mask device 64 having an opening 114 through which the exposure light beam can pass. A motor 118, which is a drive source, is fixed to the bracket 116. Further, the motor 118 is connected to a control device (not shown), and the rotation and stop of the motor 118 are controlled by the control device.

As shown in FIGS. 5 and 6, this motor 1

The rotatably supported bracket 116 and the gear 12
2D and the small gear 122B 1st driven gear 12
The large gear 122A of the two gears is meshed with the drive gear 120.

Further, the small gear 1 of the first driven gear 122.
The second driven gear 124, which is rotatably supported by the bracket 116 and in which the operating pin 126 is planted, is provided at 22B.
But they are meshed. Then, the operating pin 126
Penetrates through a through hole 116 </ b> A formed in the bracket 116 in an arc shape so as to allow the actuating pin 126 to pivot along with the rotation of the second driven gear 124.

On the other hand, above the frame 112, an upper frame 132 formed by being combined in a rectangular shape so as to allow the exposure light rays to pass therethrough is located. The upper frame 132 is shown inside. A light source unit 138 for sub-exposure in which a lamp is installed is screwed, and this lamp (not shown) produces a light beam for contact printing exposure of an image different from the projection exposure light beam from the negative film N on the photographic printing paper P. I will let you.

The upper ends of the sliding pins 134 extending downward are fixed around the four corners of the upper frame 132. On the other hand, four bushes 128 are attached to the frame 112, and four sliding pins 134 extending from the four corners of the upper frame 132 are provided.
The middle part of each is slidably fitted.

The lower ends of these four sliding pins 134 are located below the frame 112 and are combined in a rectangular shape so that the exposure light beam can pass through the inside thereof. , Respectively.

That is, the upper frame 132 and the lower frame 136 are connected via the four sliding pins 134, and the upper frame 132 and the lower frame 136 are connected to each other.
The sliding pin 134 constitutes a holding member supported by the frame 112 so as to be linearly movable, and these upper frames 132,
The lower frame 136 and the sliding pin 134 can integrally move linearly in the conveyance path direction of the printing paper P, which is the downward direction in the figure.

A coil spring 140, which is an elastic body and is arranged to push up the upper frame 132, is wound around the sliding pin 134 between the bush 128 and the upper frame 132. Therefore, the upper frame 132 and the lower frame 13
The coil spring 140 always urges 6 upward.

Further, when the paper mask 160 for positioning the photographic printing paper P is loaded in the mask device 64 at positions near the right end side and the left end side of the lower frame 136, the paper mask 160 is guided and held. The guide members 142 and 144 are fixed. Therefore, the lower frame 136 holds the paper mask 160 via the guide members 142 and 144, and when the lower frame 136 moves up and down in FIG.
The 60 also moves up and down integrally.

On the other hand, as shown in FIG.
Paper mask 16 to be loaded in the frame 112 of the
At 0, an image mask window 162 for exposing an image recorded on the negative film N and a character printing mask window 164 illuminated by a lamp in the light source unit 138.
And are formed. This character burning mask window portion 164
As is well known, for example, a squirrel film 170 on which characters such as "graduation anniversary" are recorded is attached. Further, a grip portion 166 for an operator to hold the paper mask 160 is attached to the base end side of the paper mask 160.

A display member 168 for discriminating the front side and the back side of the paper mask 160 is installed in the lower left side portion of the paper mask 160. In addition, the frame 11 corresponding to the display member 168 of the paper mask 160.
2 is provided with a sensor (not shown) formed of a transmissive photo sensor for detecting the presence or absence of the display member 168. This sensor is connected to the above-mentioned control device (not shown), and based on a signal from the sensor, this control device determines whether the paper mask 160 is erroneously loaded.

That is, the mask device 64 has a sensor,
The presence or absence of the display member 168 on the side of the paper mask 160 allows the control device to recognize the front and back surfaces of the paper mask 160 and the loading of other paper masks (for example, for printing paper of different sizes, for test printing, etc.). For example, the operator is informed of the erroneous loading of the paper mask 160 by sounding a buzzer or the like.

On the other hand, as shown in FIGS. 5 and 6, the frame 1
A rotating arm 146, which is formed by being combined in a rectangular shape so that the exposure light beam can pass through the inside, is arranged in the inside 12. The base end side of the rotating arm 146 has the rotating shaft 1
It is rotatably supported by the frame 112 via 48,
The sliding pin 134 penetrates the rotating arm 146.

Further, on the tip side of the rotating arm 146,
A standing wall portion 146A that is bent and raised is formed, and the standing wall portion 146A is formed with a recess 150 into which the operating pin 126 can be loosely fitted, as shown in FIG. A pair of coil springs 154 wound around the support pins 152 planted in the lower frame 136 are arranged between the base end side and the tip end side of the rotating arm 146 (only one side is shown in the figure). The coil springs 154 constantly urge these members so as to spread the space between the rotating arm 146 and the lower frame 136.

As described above, as the second driven gear 124 rotates, as shown in FIG. 8, when the operating pin 126 pivots and moves downward, the standing wall portion 146A of the rotating arm 146 is moved.
The rotation arm 14 hits the bottom of the recess 150 formed in the
The tip side of 6 is pushed down around the rotation shaft 148. Therefore, the middle part of the rotating arm 146 also approaches the lower frame 136, and as a result, the coil spring 1
54, the biasing force of the coil spring 154 overcomes the biasing force of the coil spring 140, and the rotating arm 146 resists the biasing force of the coil spring 140, as shown in FIG. Also, the lower frame 136 is pushed down.

That is, on the lower frame 136 in FIG.
With the downward movement, the upper frame 132 and the light source unit 138, which are connected via the sliding pin 134, are integrally lowered.

Then, the driving rotation of the motor 118 is converted into a linear motion to move the lower frame 136 to the photographic paper P on the transport path.
Drive gear 120, driven gear 122 for moving to the side,
124, the operation pin 126, the rotating arm 146, the coil spring 154, and the like constitute a power transmission mechanism.

Next, the operation of this embodiment will be described. First, the motor (not shown) is rotated to convey the photographic printing paper P by the endless belt 44, and when the photographic printing paper P is conveyed under the mask device 64 as shown in FIG. It is temporarily stopped.

In this state, when the control device energizes the motor 118, the motor 118 rotates, and this rotation is transmitted to the rotating arm 146 via the rotation of the driven gears 122 and 124 and the rotation of the operating pin 126. Then, the rotating arm 146 is rotated clockwise in FIG.

Along with this, the biasing force of the coil spring 154 increases, the biasing force of the coil spring 154 overcomes the biasing force of the coil spring 140, and the lower frame 136 is pushed down as shown in FIGS. 7 and 8. It will be.

At this time, the lower frame 136 is supported by the frame 112 so as to be linearly movable toward the conveyance path of the printing paper P, and the paper mask 160 is supported on the lower frame 136.
Since the paper mask 160 is held, the paper mask 160 is moved together with the lower frame 136 by the motor 118 so as to descend toward the photographic paper P on the transport path.

As a result, the paper mask 160 contacts the printing paper P so as to sandwich the printing paper P between the endless belt 44 and the printing paper P, and the printing paper P is positioned. In this state, the black shutter 41 is opened for a predetermined time. Thus, the image recorded on the negative film N is printed and exposed on the photographic printing paper P.

As described above, since the paper mask 160 can be linearly moved in the direction orthogonal to the plane of the photographic paper P as the lower frame 136 is linearly lowered, the photographic paper P can be conveyed. Unlike the mechanism for rotating the paper mask to release it, the entire paper mask 160 largely escapes upward. Therefore, when the photographic printing paper P is conveyed, there is no possibility that the photographic printing paper P will come into contact with the paper mask 160, and the loading blind plate becomes unnecessary.

At this time, the motor 118 that can be driven and rotated is used as a drive source so that the drive transmission of the motor 118 is converted into linear motion by the power transmission mechanism to move the lower frame 136 to the photographic paper P side. did. Therefore, since the motor 118 is used as the drive source, the paper mask 160
Although it moves linearly, it is no longer necessary to use a drive source such as a solenoid, and no noise is generated as in the case of using a solenoid or the like.

On the other hand, the motor 118 moves the lower frame 136 to the photographic paper P side while resisting the urging force of the coil spring 140 that urges the upper frame 132 and the lower frame 136 in the direction away from the photographic paper P. The paper mask 160 is abutted to position the photographic paper P. Therefore, by driving and rotating the motor 118, the paper mask 160 is moved to the side of the photographic paper P to be positioned, and after the printing and exposure, the power supply to the motor 118 is simply stopped.
Coil spring 140 ensures paper mask 16
0 is returned to the original position, and when the photographic printing paper P is conveyed, the photographic printing paper P is more surely set to the paper mask 16
There is no risk of touching 0.

On the other hand, when the paper mask 160 contacts the printing paper P and positions the printing paper P, the endless belt 44
Even if there is a tilt, the two coil springs 154 are arranged between the rotating arm 146 and the lower frame 136, so that this tilt can be absorbed, and the printing paper P of the appropriate paper mask 160 can be absorbed. Contact is secured.

Further, the light source unit 138 attached to the upper frame 132 is adapted to generate a light beam for printing and exposing on the photographic printing paper P an image different from the exposure light beam from the negative film N. Therefore, the black shutter 4
By burning the lamp in the light source unit 138 at the same time as opening 1, the characters such as "graduation anniversary" different from the exposure light beam from the negative film N are printed on the photographic paper P together with the image of the negative film N. Is now possible. As a result, the image portion P1 formed by the negative film N and the character portion P formed by the lith film 170 as shown in FIG.
A photo print with 2 is completed.

Although the coil spring is used as the elastic body in the above embodiment, another spring such as a torsion spring or a leaf spring may be adopted, or another material such as a rubber material may be used.

When printing an image of the negative film N on the photographic printing paper P having a size different from that of the above embodiment, it is necessary to replace the paper with a paper mask having a window portion having a size matching the size of the photographic printing paper. Of course, in the above embodiment, the light source unit 138 for the sub-exposure is used as an example. However, the light source unit 138 is not installed if it is not necessary to print characters or an illustration or a negative film in close contact. Good.

On the other hand, a light source unit of another size may be attached, or a plurality of light source units may be attached, and the image on the lith film 170 as the contact printing original plate may be a figure or a figure other than characters. It may be an illustration or the like.
