[Example of device]

1 and 2 show a film carrier 10 to which the present invention is applied.
It is shown.

In the film carrier 10, the base plate 14 fixed to the base block 12 is mounted and supported on the support base 16 of the printing apparatus. In this case, the support base 16 has a plurality of positioning pins 18 projecting from the base plate.
When the positioning hole 20 formed in 14 coincides with this, positioning can be accurately performed on the optical axis P.

(Explanation of Fixed Carrier Base and Lower Mask) A fixed carrier base 22 is fixed to the upper portion of the base block 12. The fixed carrier base 22 is designed so that the film carrier 10 can be removed from the support base 16 by an operator supporting and lifting the end portion protruding from the base block 12 in the left-right direction of FIG. Therefore, the cover plate 24 fixed to the support 16 of the printing apparatus is provided with a recess 26 so that an operator can insert his / her finger below the fixed carrier base 22. Further, the cover plate 24 is formed with a guide hanging portion 24A corresponding to both sides of the base block 12, and when the film carrier 10 is mounted on the support base 16, the base block 12 is guided to the hanging portion 24A. It can be inserted while being inserted. Therefore, the vertical portion 24A may be tapered so that the inner diameter gradually decreases toward the lower end.

A film (not shown) is inserted onto the fixed carrier base 22 in the direction of arrow A and fed to the optical axis P.

A lower mask 30 and an upper mask 32 are arranged on the fixed carrier base 22 corresponding to the lower side and upper side of the film fed onto the optical axis P.

The lower mask 30 has a thin plate shape as shown in FIGS. 6 and 8, and has an aperture 34, which is a printing opening for determining the size of a printing image, formed coaxially with the optical axis P in the central portion. There is. Also, this lower mask 30 is a fixed carrier base
The magnet 33 is housed in a recess 22B formed in 22 and is embedded in the recess 22B so as to be attracted. Further, the lower mask 30 forms the same plane as the film guide surface 22A, so that the film can be smoothly guided. Therefore, the lower mask 30 has chamfers 30A and 30B formed on the upstream and downstream end surfaces of the aperture 34.

Further, chamfers 22C and 22D corresponding to the chamfers 30A and 30B are formed on the upper ends of the recesses 22B so that the film F can be smoothly transferred from the film guide surface 22A onto the lower mask 30. Further, as shown in FIG. 9, the lower mask 30 has the maximum width dimension B of the portion corresponding to the widthwise central portion of the film F conveyed in the direction of arrow A. From this maximum width dimension portion, as shown in FIG. The width dimension is reduced in the vertical direction. Further, the recess 22 for accommodating the lower mask 30
B has the same shape. This makes the lower mask 3
A gap S formed between the outer peripheral portion of 0 and the inner peripheral portion of the recess 22B.
Has a V-shape whose longitudinal direction is displaced from the line in the film width direction. Therefore, even when the leading end portion of the film F conveyed in the direction of the arrow A is curled downward, the leading end portion of the film F and the recessed portion 22 of the lower mask 30.
It is possible to easily pass through and move to the optical axis P without entering the gap S between the edge of B and the edge.

The lower mask 30 is provided with a protrusion 36 corresponding to one side of the moving path of the film F, and one surface of the protrusion 36 corresponds to the widthwise end face of the film F. For this reason, it is for positioning when the film F is inserted into the optical axis P in the direction perpendicular to the direction of the arrow A, that is, in the direction of the arrow C from the lower side of FIG.

As shown in FIGS. 1 and 2, the fixed carrier base 22 has grooves 28A, 28B formed on the upstream side and the downstream side of the optical axis P and the aperture 34 for accommodating the film F and guiding it in the arrow A direction. Has been done.

(Explanation of the upper mask) As shown in FIG. 6, the upper mask 32 is a mask main body.
40 is formed of a flat plate, and an aperture 42 corresponding to the optical axis P is formed in the center. The aperture 42 has an opening area larger than that of the aperture 34, and has a role of being pressed by the lower mask 30 to sandwich the periphery of the printed image of the film F.

A compression coil spring 46 is inserted around the pin 44 standing upright from the four corners of the mask body 40, the tip of the pin 44 penetrates the holder 48, and a retaining ring 50 is attached. Therefore, the mask main body 40 is pressed against the lower mask 30 by the pressing force of the compression coil spring 46. An aperture 52 similar to the mask body 40 is also formed in the holder 48 coaxially with the optical axis P. The mask body 40 and the aperture 42 have the largest width dimension at the widthwise central portion of the film F through which the outer shape of the lower mask 30 shown in FIG. 9 passes, and the leading end portion of the film F has an upward curl. Even in the case of the opening, the edge portion of the aperture 42 is not caught.

A protruding piece 48A is projected from a part of the holder 48, and the holder 48 is inserted into the rotating bracket 54 to be assembled. The rotating bracket 54 is formed of a thin plate material, and has leg plates 54A bent at right angles on both sides thereof, and is pivotally supported by a pin 56 to a part of the base plate 14 as shown in FIGS. . The pin 56 is arranged in parallel with the arrow A direction.

A cover plate 60 is fixed to the top surface of the rotating bracket 54 with four screws 58. The cover plate 60 is formed with a recess 60A for accommodating the protrusion 48A between the cover plate 60 and the top surface of the rotating bracket 54. Therefore, the protrusion 48A can be inserted into the recess 60A in the direction of arrow C.

The cover plate 60 is provided with a concave portion 60A, and an L-shaped groove having a convex shape toward the upper mask 32 in a thinned portion.
62 is penetratingly formed, thereby forming a cantilevered arm 64 protruding toward the upper mask 32.

As shown in FIG. 10, the arm 64 has a rotating bracket.
A hemispherical recess 64A is formed facing 54, and the semicircular surface of the ball 66 is housed therein. Therefore, a part of the ball 66 is in contact with the rotating bracket 54, and when the protruding piece 48A is inserted into the recess 60A, the arm 64 is elastically deformed and lifted,
When the ball 66 is inserted into the groove 48B formed in the projecting piece 48A, the ball 66 positions the upper mask 32 and holds the upper mask 32 on the rotating bracket 54 and the cover plate 60. It is preferable to determine the width dimension of the protrusion 48A and the width dimension of the recess 60A so that the upper mask 32 does not rattle in the lateral direction.

As shown in FIG. 4, a torsion coil spring 68 is attached to the pin 56 which pivotally supports the rotating bracket 54, so that the upper mask 32 is always urged to rotate away from the lower mask 30, that is, clockwise in FIG. Is given. The torsion coil spring 68 applies this rotational force, and at the same time, the coil portion has a biasing force that expands in the axial direction of the pin 56,
The leg plate 54A also serves as a compression coil spring which produces a biasing force in the direction away from the bracket 14A of the base plate 14, that is, in the right direction in FIG. As a result, the upper mask 32 is accurately positioned with respect to the lower mask 30 in the direction of arrow A.

The rotating bracket 54 has a protrusion 54 on the opposite side of the upper mask 32.
B protrudes and corresponds to the cylindrical cam 70 shown in FIG. As shown in FIG. 3, the cylindrical cam 70 has a compression coil spring 72 interposed between the cylindrical cam 70 and an arm 22E protruding from a part of the fixed carrier base 22, and a rotating lever 74 mounted on the top surface of the arm 22E. Are connected with bolts 76. The axis of the bolt 76 is vertical, and the turning lever 74 rotates the cylindrical cam 70 if an operator rotates it around the axis of the bolt 76 when necessary, thereby rotating the cylindrical cam 70.
32 is connected so that it can be operated to move up.

To explain this in detail, the cylindrical cam 70 has a cylindrical upper end surface 70A.
The projection 54B corresponds to the projection 54B, the projection 54B is
There is a slight gap between the upper mask 70A and 70A, and as shown in FIG. When the cutout portion 70B corresponds to the projection 54B, the projection 54B can enter the cutout portion 70B, so that the upper mask 32 is in a wide open state in which the upper mask 32 can be rotated by a large angle θ2. .

As a result, when the cutout portion 70B corresponds to the protrusion 54B, the upper mask 32 is automatically rotated to the upper end of the angle θ2 by the urging force of the torsion coil spring 68, and the upper mask 32 forms a large film insertion space with the lower mask 30. Like

As shown in FIG. 3, a solenoid 78 is provided corresponding to the lower surface of the rotating bracket 54, and the upper mask 32 that has risen to the upper limit of the angle θ1 is attracted to a substantially horizontal state by the exciting force of the solenoid 78 and is masked. The film F is pressed against the lower mask 30 so that the film F can be baked by the main body 40 to maintain the flat state.

Further, as shown in FIG. 6, a resin block 80 is fixed to the lower surface of the rotary bracket 54 and corresponds to the rubber 84 fixed to the head of a screw 82 screwed to the base plate 14. The resin block 80 and the rubber 84 form a stopper, and have a role of limiting the amount of movement of the mask body 40 in the pressing direction to the lower mask 30 in a state where the upper mask 32 is attracted by the solenoid 78.

That is, the holder 48 rotates in a substantially horizontal state until it is attracted to the solenoid 78 together with the rotating bracket 54.
40 is an upper mask 32 through the urging force of the compression coil spring 46.
Holder 48 is directly pressed against the mask body.
No force is generated to press 40 against the lower mask 30. However, since the compression force applied to the compression coil spring 46 changes depending on the stop positions of the upper mask 32 and the rotary bracket 54, the screwing amount of the screw 82 to the base plate 14 is adjusted to limit this. .

In addition, the resin block 80 is in close contact with the rubber 84 and the rotating bracket.
Since the rotation angle of 54 is limited, the rotating bracket 54 does not come into close contact with the solenoid 78, and noise does not occur when the rotating bracket 54 comes into close contact with the solenoid 78.

(Description of Film Drive Unit) Drive shafts 92 and 94 are axially supported on the upstream side (left side in FIGS. 1 and 2) and the downstream side of the optical axis P, respectively. As shown in FIG. 11, the drive shaft 92 is fixed to the carrier base 22 via a bearing 96.
The shaft center is parallel to the arrow C direction. The drive shaft 92 is also supported by a similar structure.

A ring 98 is fixed to the drive shafts 92, 94 at an intermediate portion in the axial direction with a predetermined distance. These rings 98 are exposed to the top surface of the fixed carrier base 22 through the through holes 22F formed in the fixed carrier base 22. This ring
The outer peripheral surface of 98 is flush with the surface of the film guide surface 22A, or protrudes by a slight amount.

Further, as shown in FIG. 2, the driving force from the motor 100 is transmitted to the driving shafts 92 and 94 through the timing belt 102 to generate the film driving force.

(Description of Pressing Roller) Pressing roller shafts 110 and 112 are arranged on the upstream side and the downstream side of the optical axis P corresponding to the drive shafts 92 and 94, and the pressing rollers 111 and 113 are respectively provided on both ends in the axial direction. It is supported. The pressing rollers 111 and 113 sandwich the film F between the driving shafts 92 and 94 and the ring 98, and generate a driving force in the arrow A direction on the film F.

Small-diameter taper rollers 111A and 113A are axially supported between the pressing rollers 111 and 113 to position the pressing rollers without contacting the film F.

Both ends of these pressing roller shafts 110 and 112 are supported by rotating brackets 114 and 116, respectively, and are arranged such that the pressing rollers 111 and 113 are in contact with the ring 98 and the axes thereof are horizontal. . These pivot brackets 114 and 116 are attached to the pin 11
8 and 120 are pivotally supported by fixed brackets 122 and 124, respectively. These fixed brackets 122 and 124 are leg plates so that they are U-shaped with the lower part open as shown in FIG.
122A, 122B and leg plates 124A, 124B are extended, leg plate 122B,
At the tip of 124B, the mounting plate 126 is extended horizontally and screws 128
It is fixed to the fixed carrier base 22 to form a cantilever arm. A torsion coil spring 130 is interposed between the fixed brackets 122 and 124 and the rotary brackets 114 and 116 to generate an urging force for pressing the pressing rollers 111 and 113 against the ring 98.

(Explanation of Film Guide Means) A fixed carrier base 22 is provided further downstream of the pressing roller 112.
Guide plate 140 that forms a narrow film guide space between
Are arranged. As shown in FIG. 2, the guide plate 140 has an upstream end located on the side opposite to the optical axis P via the pressing roller 113 and at a distance from the film guide surface 22A, and the vicinity of the downstream end. It is fixed to the lifting bracket 142.

This lifting bracket 142 is a leg plate 142 that is erected from both sides.
A is fixed by horizontal pin 144 Bracket 14 of carrier base 22
It is pivoted to 5. The horizontal pin 144 has an axis parallel to the direction of arrow A, and the guide plate 140 applies a biasing force to the film guide surface 22A by the biasing force of the torsion coil spring 146 mounted on the outer periphery. . However, the guide plate 140 is arranged so as not to come into contact with the film guide surface 22A.

Therefore, the guide plate 140 guides the film F sent from the pressing roller 112 to the downstream side between the film F and the film guide surface 22A.

On the upstream side of the pressing roller 111, a fixed guide plate 15 is provided to a fixed bracket 122 via an arm 148 as shown in FIG.
0 is attached, and a guide space is similarly formed between the film F and the film guide surface 22A to guide the film F to the pressing roller 111.

(Description of Bar Code Reading Unit) A bar code reading unit 160 is provided on the upstream side of the pressing roller 111. As shown in FIG. 5, the bar code reading section 160 has a housing 162 pivotally supported by a pin 166 to a bracket 164 protruding from the fixed carrier base 22. The pin 166 is arranged such that its axial center is parallel to the direction of arrow A, and is pressed against the film F passing through the housing 162 by the urging force of the torsion coil spring 168.

As a result, the lower end surface 162A of the housing 162 is in contact with the film guide surface 22A. Like the torsion coil spring 68, the torsion coil spring 158 has a coil portion which also functions as a compression coil spring, and presses the housing 162 to the right in FIG.
The positioning of 160 in the direction of arrow A is also performed.

Inside the housing 162, a pair of pins 170 parallel to the arrow A direction
The pressing arm 172 is pivotally supported by. The pressing arms 172 are pressed toward the widthwise ends of the film F by the biasing force of the compression coil spring 174 interposed between the pressing arm 172 and the housing 162, and are pressed toward the widthwise ends of the film F. It is designed to follow. Therefore, the sensor 176 fixed to these pressing arms 172 always keeps the film F.
The bar code as a side print, which is arranged at a predetermined distance from the widthwise end face of the film F and is formed at a specific position from the widthwise end face of the film F, can be appropriately read. A film type, frame number, etc. are recorded in this barcode.

A pressing roller 178 is axially supported on the housing 162 via a leaf spring bracket 179 (FIG. 2) corresponding to an intermediate portion of the pair of sensors 176, and abuts against one side of the passing film F, and the film guide surface 22A. Film guide plate 180 that forms the extension surface of
Corresponding to the pressing roller 182 pivotally supported by. The pressing roller 178 and the pressing roller 182 have a role of pressing the center portion in the width direction so that the film F, which is pressed by the pressing arm 172 in the width direction, does not bend.

A transparent glass 184 is attached to the film guide plate 180 corresponding to the bar code recording portion of the film F, and a light projecting means 186 is provided on the lower surface thereof. This transparent glass 1
As shown in FIG. 12, 84 is a film guide plate 180 on which a projection 180A for enlarging the widthwise dimension is formed in a substantially semicircular shape.
This is because the bar code formed on the film F is the film F.
This is because they are arranged extremely close to the widthwise end of the. Therefore, the pressing arm 172 is also formed with a recess 172B for accommodating the protrusion 180A corresponding to the protrusion 180A.

As shown in FIG. 12, on the upstream side of the pressing arm 172, there is provided a detection arm 190 whose tip is bent in an arc shape. The detection arm 190 produces a biasing force that presses the widthwise end of the film F. Therefore, when the film F is a long negative film in which short negative films are connected, if there is a notch previously formed corresponding to the connecting portion, the film enters into this notch and activates the limit switch 192. The solenoid 194 provided in the housing 162 is urged to separate the pressing arms 172 from each other, and the feeding failure due to the contact of the film connecting portion with the facing surface 172A of the pressing arm 172 does not occur.

Further, a reflection sensor 196 is provided to give the same function as that of the detection arm 190. The reflection sensor 196 is adapted to detect a reflection portion such as an identification tape which is previously applied to the film joint, or to detect a change in the amount of light transmitted through the adhesive tape portion, and similarly actuate the solenoid 194.

(Description of interlocking mechanism) Pressing rollers 111, 113, guide plate 140, bar code reading unit 1
An interlocking mechanism is provided to manually operate 60 to open the film passage.

This interlocking mechanism has an operating shaft 212 whose axial center is arranged parallel to the arrow C direction on the fixed bracket 124. This operation shaft 212 has its front end protruding from the leg plate 124A so that the operation knob 214
Is stuck. Further, the intermediate portion of the operating shaft 212 is formed as a notch plane portion 212A, and corresponds to the lower surface of the rotating bracket 116. That is, the operating shaft 212 has the pressing roller 113 in a state where the notched flat surface portion 212A corresponds to the lower surface of the rotating bracket 116.
When the operating knob 214 is rotated in the direction of arrow F in FIG. 7, the outer peripheral surface of the operating shaft 212 twists the rotating bracket 116 around the pin 120 and the coil spring 13 rotates.
The pressing roller 113 is rotated against the biasing force of 0 to separate the pressing roller 113 from the ring 98.

A link 218 is attached to the tip of the operating shaft 212 protruding from the leg plate 124A.
One end of is stuck. The pin 220 protruding from the tip of the link 218 is connected to the arm 224 of the slide lever 222. As shown in FIG. 1, the slide lever 222 has an elongated hole 228 arranged on the fixed carrier base 22 and through which a pin 226 protruding from the fixed carrier base 22 passes. The axis of the elongated hole 228 is parallel to the arrow A direction. Therefore, when the operation knob 214 is rotated in the arrow F direction, the slide lever 222 slides in the arrow G direction in FIG.

The slide lever 222 has a pair of leg plates 230 integrally projected at the downstream end in the film transport direction, and holds a roller 232 by a pin 234. The roller 232 corresponds to the swash plate cam 142B formed at the end of the elevating bracket 142. Therefore, in this roller 232, the slide lever 222 has an arrow G.
When the swash plate cam 142B is moved downward, the lifting bracket 142 and the guide plate 140 are rotated about the horizontal pin 144 against the biasing force of the torsion coil spring 146, and the guide plate 140 is guided by the film. A large open space is formed with the surface 22A.

An arm 236 formed at the upstream end of the slide lever 222 in the film transport direction is connected to one end of a link 240 via a pin 238. The other end of the link 240 is fixed to the end of the rotary shaft 242. This rotary shaft 242 is a leg plate
The shaft center is axially supported by 122A and 122B in parallel with the direction of arrow C, and similarly to the case of the operating shaft 212, a notched flat surface portion 242A is formed and corresponds to the lower surface of the rotary bracket 114. Therefore, the notch plane portion 242A enables the pressing roller 111 to abut on the ring 98 when corresponding to the rotating bracket 114, but when the slide lever 222 is driven in the direction of arrow G, the outer peripheral surface of the rotary shaft 242. Corresponds to the rotating bracket 114, the rotating bracket 114 is rotated around the pin 118 so that the pressing roller 111 is separated from the ring 98.

An arm 246 is fixed to the tip of the rotary shaft 242 protruding from the leg plate 122A. The tip of this arm 246 is housing 162
When the slide lever 222 is moved in the direction of arrow G, the arm 162B is pushed up to rotate the housing 162 around the pin 166 and separate it from the film F.

(Operation of Embodiment) In order to mount the film carrier 10 on the printing apparatus, the base block 12 may be inserted into the hanging portion 24A of the cover plate 24 while guiding it, as shown in FIG. Since it is possible, the insertion work is extremely easy. Further, the base plate 14 has a positioning pin 18 and a positioning hole 20.
The film carrier is accurately positioned by the optical axis P and is mounted on the support base 16.

When the film F is loaded, it may be inserted from either the arrow A direction or the arrow C direction. When the film F is inserted from the direction of arrow A, the pressing rollers 111 and 113 can be kept in contact with the rings 98 of the drive shafts 92 and 94, respectively. However, the pressing arm 172 of the barcode reading unit 160
Preferably activates solenoid 194 to keep it open.

In this way, when the film F is loaded from the direction of arrow A,
Even if the tip of the film F is curled downward or upward, the gap S between the lower mask 30 and the concave portion 22B is shifted in the longitudinal direction from the film width direction, and further chamfered 22C, 22D, 30A, 30B. Thus, the film F can be smoothly slid and moved on the film guide surface 22A and the lower mask 30.

When inserting the film F from the direction of arrow C, the operation knob
Rotate 214 in the direction of arrow F. This allows the operating axis 212
Rotates the rotating bracket 116 so that the pressing roller 113 rises apart from the ring 98, and the rotary shaft 242 which receives the driving force of the operation knob 214 via the slide lever 222 pushes up the rotating bracket 114, so that the pressing roller 111 also moves. Ring 98 as well
The film guideway is opened wide apart.

Further, since the slide lever 222 moves in the direction of arrow G, the elevating bracket 142 is rotated around the horizontal pin 144 via the roller 232 and the swash plate cam 142B, the guide plate 140 is also largely separated from the film guide surface 22A. Further, the bar code reading unit 160 also receives the rotational force of the rotary shaft 242 and is raised by the arm 162B, so that the film guide path is largely opened.

Therefore, the film F can be easily inserted from the direction of the arrow C. In this case, since the upper mask 32 is raised by the angle θ1 by the urging force of the torsion coil spring 68, the mask main body 40 similarly opens the film guide path largely. Further, the rotating lever 74 may be rotated to raise the upper mask 32 to the upper limit of the angle θ2 in FIG.

When the operation knob 214 is returned to its original state after the film F is inserted until it coincides with the optical axis P, the rotary brackets 114 and 116 have the flat cutout portions 242A and the flat cutout portions 212A.
4 and 116, the pressing rollers 111 and 113 are pressed against the ring 98 by the urging force of the torsion coil spring 130 to clamp the film F. Along with this, the guide plate 140 also descends to the state shown in FIG. 2 by the urging force of the torsion coil spring 146 to form a film guide path between itself and the film guide surface 22A.

Further, the housing 162 is also lowered by the urging force of the torsion coil spring 168, and the pressing arm 172 lightly presses both ends of the film F.

Here, a predetermined image pattern is made to coincide with the optical axis P while moving the film F in the direction of arrow A.

At the time of printing, when the upper mask 32 is lowered by driving the solenoid 78, the mask body 40 presses the film F to the lower mask 30, and the periphery of the printing image is sandwiched so that the printing image becomes a flat state, and printing from a light source (not shown) is performed. A light-sensitive material (not shown) is printed with light.

As described above, when the upper mask 32 is lowered by the urging force of the solenoid 78, the lowering operation of the rotating bracket 54 is stopped by the resin block 80 coming into contact with the rubber 84. It does not add to the main body 40, and there is no noise when stopped.

After that, the film F prints another image frame corresponding to the optical axis P, but the printing operation is the same as described above. When the film F is fed, the ring 98 is driven by the motor 100.
It is possible to rotate by to feed quickly.

Further, when replacing the upper mask 32, if the notch 70B is made to correspond to the protrusion 54B by rotating the rotating lever 74, the upper mask 32 is biased by the torsion coil spring 68 to form an angle θ2.
Rotate the upper mask 32 as it is raised only by the bracket 54
It can be removed from the machine for inspection or replaced with another upper mask 32. Further, even when the lower mask 30 is replaced, the operation is convenient if the upper mask 32 is largely raised.

When replacing the mask main body 48 and the holder 48 of the upper mask 32, the holder 48 is pulled out from the rotating bracket 54. The new holder 48 with another mask main body 48 attached is inserted into the recess 60A by a predetermined amount, so that the ball 66 of the arm 64 is inserted into the groove 48.
The holder 48 is positioned by entering the inside of B.

The bar code reading unit 160 is used when the drive shafts 92 and 94 are rotated by the drive force of the motor 100 to continuously print a plurality of image frames of a long film. That is, the pressing arm 172 lightly presses both end portions of the film F to cause the sensor 176 to accurately correspond to the bar code recording position of the film F. Even if the follow-up position of the sensor 176 is slightly changed, the bar code cannot be read. Generally, this deviation is required to be 0.1 mm or less.

Therefore, the bar code such as the film type and the frame number recorded on the film F can be properly read, and the printing conditions at the time of printing can be changed and the printed image frame can be recorded.

The pressing arm 172 of the bar code reading section 160 is a film F.
After passing, the opposing surface 172A is pressed against both sides of the film guide plate 180 by the urging force of the compression coil spring 174, so that the opposing distance becomes narrower than the width dimension of the film F by about 0.2 mm.
When the next film F is inserted, the rigidity of the film F causes the film F to be pushed and expanded again to correspond to both side surfaces of the film F.

Further, when a plurality of films are connected and the connection splice portion is detected by the detection arm 190 or the reflection sensor 196, the solenoid 194 is excited, and the pressing arm 172 temporarily holds the width direction end surface of the film F. Be separated from. As a result, the pressing arm 172 is caught by the splice portion and does not hinder the film feeding.

In the above embodiment, the fixed guide plate 15 on the upstream side of the optical axis
The configuration may be such that 0 is moved up and down like the guide plate 140 on the downstream side of the optical axis.

[Effect of device]

Since the present invention is configured as described above, the upper mask can be quickly brought close to the lower mask at the time of printing, and the upper mask can be widely opened for easy replacement when the upper mask is replaced.
