Abstract

PURPOSE:To surely read a side print such as a bar code which is recorded on a film by providing a side print reading sensor which is pressed toward both edges in the cross direction of a film and a holding means which prevents a film from bending by means of holding the middle in the cross direction. CONSTITUTION:A press arm 172 lightly presses both edges of a film and surely associate the sensor 170 with the bar code recording position of a film. Minute shift of the follow-up position of this sensor 176 causes impossibility of bar code reading. Commonly, this shift should be <=0.1mm. The facing surface 172A of the press arm 172 of this bar code reading part 160 is pressed toward both sides of a film guide plate 180 by an energized compression coil spring 174 after a film passed through. Interval becomes narrower than the size of width of a film, and when the following film is inserted, it is widened again by the rigidity of a film corresponding to the both sides of a film. Thus, a side print which is displayed to the prescribed position from the edges in the cross direction of a film can be precisely read.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a film side print reading device for reading side prints recorded near the widthwise ends of a film.

[Background technology]

2. Description of the Related Art A printing apparatus that prints an image from a negative film onto a photosensitive material sometimes reads a bar code that is displayed in advance near the widthwise end of the negative film. This barcode displays the film type, frame number, etc.

However, since this barcode is displayed at a predetermined position from the end in the width direction of the film, it is difficult to make the reading sensor accurately follow the display position of this barcode.

The present invention has been made in consideration of the above facts, and an object of the present invention is to provide a film side print reading device that can reliably read side prints such as bar codes recorded on a film.

[Summary and operation of the invention]

The present invention includes a side print reading sensor that is pressed toward both ends in the width direction of the film being transported toward the printing section;
The present invention is characterized by comprising a clamping means for clamping the middle part of the film in the width direction to prevent the film from being bent.

Therefore, in the present invention, the reading sensor is moved to follow the ends of the film in the width direction, and the middle part of the film in the width direction is held by the holding means to prevent the film from being bent. Side blints applied at predetermined positions from the ends can be accurately read.

[Embodiments of the invention]

Figure 1.2 shows a film carrier 1 to which the present invention is applied.
0 is shown.

In this film carrier 10, a base plate 14 fixed to a base block 12 is mounted and supported on a support stand 16 of a printing device. In this case, a plurality of positioning pins 18 protrude from the support base 16, and the positioning holes 20 formed in the base plate 14 match with these pins, thereby allowing accurate positioning to the optical axis P.

(Description of Fixed Carrier Base and Lower Mask) A fixed carrier base 22 is fixed to the upper part of the base block 12. When the fixed carrier base 22 is lifted by supporting the end portion of the base block 12 that protrudes from the left and right directions in FIG.
It can be removed from. For this purpose, a recess 26 is formed in the cover plate 24 fixed to the support base 16 of the printing device so that the operator can insert his or her finger into the underside of the fixed carrier base 22.

Further, this cover plate 24 is formed with guiding hanging parts 24A corresponding to both sides of the base block 12, and when the film carrier 10 is placed on the support stand 16, the base block 12 is guided by these hanging parts 24A. It is now possible to insert it while For this reason, the hanging portion 24A may be bent toward the lower end to have a tapered shape in which the inner diameter gradually decreases.

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

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

As shown in Fig. 6.8, the lower mask 30 has a thin plate shape, and an aperture 34, which is a printing opening for determining the size of the printed image, is formed in the center coaxially with the optical axis P. . The lower mask 30 is accommodated in a recess 22B formed in the fixed carrier base 22, and is attracted by a magnet 33 embedded in the recess 22B.

Further, this lower mask 30 forms the same plane as the film guide surface 22A, so that the film can be guided smoothly. Therefore, this lower mask 30 has an aperture 3.
Chamfering 30A, 30 on the upstream and downstream end faces 4 of 4
B is formed.

Also, the upper end of the recess 22B is chamfered 30A130B.
Chamfers 22C and 22D corresponding to the above are formed to smoothly transfer the film F from the film guide surface 22A onto the lower mask 30.

Furthermore, as shown in FIG. 9, the lower mask 30 has a maximum width B at a portion corresponding to the widthwise central portion of the film F conveyed in the direction of the arrow. The width dimension decreases in the vertical direction. Furthermore, the recess 22B that accommodates the lower mask 30 also has a similar shape. With this, lower mask 30
The gap S formed between the outer periphery of the recess 922B and the inner periphery of the recess 922B has a 7-shaped shape with the longitudinal direction shifted from the film width direction line. Therefore, even if the leading edge of the film F that is fed in the direction of the arrow is curled downward, the leading edge of the film F will move into the gap S between the end face of the lower mask 30 and the edge of the recess 22B. It is designed so that it can easily pass by and move toward the optical axis P without entering.

This lower mask 30 is provided with a protrusion 36 corresponding to one side of the movement locus of the film F, and one side of the protrusion 36 corresponds to the end face of the film F in the width direction. Therefore, it is used for positioning when inserting the film F into the leading shaft P in a direction perpendicular to the direction of arrow entry, that is, in the direction of arrow C from the lower side of FIG.

As shown in FIG. 1.2, the fixed carrier base 22 has grooves 28A on the upstream and downstream sides of the optical axis P and the aperture 34 for accommodating the film F and guiding it in the direction indicated by the arrow.
, 28B are formed.

(Description of Upper Mask) As shown in FIG. 6, the upper mask 32 has a mask body 40 formed from a flat plate, and an aperture 42 corresponding to the optical axis P is formed in the center. This aperture 4
2 has a larger opening area than the aperture 34, and has the role of being pressed against the lower mask 30 and holding the periphery of the printed image on the film F.

A compression coil spring 46 is inserted around the pin 44 erected from the four corners of the mask body 40, and a retaining ring 50 is attached to the tip of the pin 44 passing through the holder 48. Therefore, the mask body 40 is pressed against the lower mask 30 by the pressing force of the compression coil spring 46. This holder 48 also has an aperture 52 similar to that of the mask body 40 formed coaxially with the optical axis P. Note that the mask body 40 and the aperture 42 have the same outer shape as the lower mask 30 shown in FIG. 9, with the width dimension being the largest at the center in the width direction of the film F passing through, and the leading end of the film F having an upward curl. The structure is such that it will not get caught on the edge portion of the aperture 42 even if it is.

The holder 48 has a projecting piece 48A protruding from a part thereof, and is adapted to be inserted into and assembled into the rotation bracket 54.

This rotating bracket 54 is formed from a thin plate material, and leg plates 54A bent at right angles are provided on both sides.
4. As shown in Figure 4, pin 5 is attached to a part of base plate 14.
It is pivoted at 6. This pin 56 is arranged parallel to the six directions of the arrows.

A cover plate 60 is fixed to the top surface of the rotation bracket 54 with four screws 58. This cover plate 6
0 has a recess 60A formed between it and the top surface of the rotation bracket 54 for accommodating the protrusion 48A. 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 a U-shaped groove 62 having a convex shape toward the upper mask 32 is formed through the thinned portion of the cover plate 60, thereby forming a cantilevered arm protruding toward the upper mask 32. 64 is formed.

As shown in FIG. 10, a hemispherical recess 64A is formed in this arm 64 facing the rotating bracket 54, and a half circumferential surface of a ball 66 is accommodated therein.

Therefore, a part of this ball 66 is in contact with the rotating bracket 54, and when the protrusion 48A is inserted into the recess 60A, the arm 64 is elastically deformed and lifted, and the ball 66 is lifted up.
6 is inserted into the groove 48B formed in the projection 48A, the ball 66 positions the upper mask 32 and holds it against the rotation bracket 54 and the cover plate 60. It is preferable to determine the width of the protrusion 48A and the width of the recess 60A so that the upper mask 32 does not wobble in the lateral direction.

As shown in FIG. 4, a torsion coil spring 68 is attached to the pin 56 that pivotally supports the rotation bracket 54, and a rotation biasing force is applied to always move the upper mask 32 away from the lower mask 30, that is, clockwise in FIG. is granted.

This torsion coil spring 68 not only applies this rotational force, but also has a coil portion that has a biasing force that expands in the axial direction of the pin 56, and moves the leg plate 54A away from the bracket 14A of the base plate 14, that is, the fourth It also functions as a compression coil spring that generates a biasing force in the right direction in the figure. As a result, the upper mask 32 is accurately aligned with the lower mask 3.
0 in the direction of arrow A.

A protrusion N54B protrudes from the rotation bracket 54 on the opposite side of the upper mask 32, and the cylindrical cam 7 shown in FIG.
It corresponds to 0. As shown in FIG. 3, a compression coil spring 72 is interposed between this cylindrical cam 70 and an arm 22E protruding from a part of the fixed carrier base 22, and a rotating lever 7 is attached to the top surface of the arm 22E.
4 and are connected by bolts 76. The axis of this bolt 76 is vertical, and when an operator rotates the rotating lever 74 around the axis of the bolt 76 when necessary, the cylindrical cam 70 is rotated and the upper mask 32 is raised. are connected so that

To explain this in detail, the cylindrical cam 70 has a cylindrical upper end surface 7
When 0A corresponds to the protrusion 54B, there is a slight gap between the protrusion 54B and the cylindrical upper end surface 70A, and as shown in FIG. The angle θ between the tilted state and the amount
1 can be rotated and is in a slightly open state, and the notch 7OB
corresponds to the protrusion 54B, the protrusion 54B corresponds to this notch 70.
Since the upper mask 32 can enter into the inside B, the upper mask 32 becomes in a wide open state where it can be rotated until the upper mask 32 is raised by an angle θ2.

As a result, when the notch 70B corresponds to the protrusion 54B, the upper mask 32 is automatically rotated to the upper end of the angle θ2 by the biasing force of the torsion coil spring 68.
2 forms a large film insertion space between it and the lower mask 30.

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, which has been raised to the upper limit of the angle θ1, is attracted to a substantially horizontal state by the excitation force of the solenoid 78, and the upper mask 32 is attracted to a substantially horizontal state by the excitation force of the solenoid 78. Main body 40
It is possible to print the film F by using the lower mask 3.
It is pressed to 0 to maintain the flat state.

Furthermore, as shown in FIG. 6, a resin block 80 is fixed to the lower surface of the rotating bracket 54, and a rubber block 84 is fixed to the head of a screw 82 that is screwed into the base plate 14.
It corresponds to This resin block 80 and rubber 84 constitute a stopper, which has the role of limiting the amount of movement of the mask body 40 in the pressing direction toward the lower master 30 when the upper mask 32 is attracted by the solenoid 78.

That is, the holder 48 rotates together with the rotating bracket 54 to a substantially horizontal state until it is attracted to the solenoid 78. However, since the mask body 40 is pressed toward the upper mask 32 through the biasing force of the compression coil spring 46, the holder 48 does not directly generate a force that presses the mask body 40 against the lower mask 30.

However, the compressive force applied to the compression coil spring 46 changes depending on the stopping position of the upper mask 32 and the rotating bracket 54, so in order to limit this, the amount by which the screw 82 is screwed into the base plate 14 is adjusted. .

In addition, since the resin block 80 is in close contact with the rubber 84 and the rotation angle of the rotation bracket 54 is limited, the rotation bracket 54
does not come into close contact with the solenoid 78, and no noise is generated due to the rotation bracket 54 coming into close contact with the solenoid 78.

(Description of Film Drive Section) Drive shafts 92 and 94 are supported on the upstream side (left side in FIG. 1.2) and downstream side of the optical axis P, respectively.

As shown in FIG. 11, the drive shaft 92 is pivotally supported by the fixed carrier base 22 via a bearing 96, and its axis is parallel to the direction of arrow C. The drive shaft 92 is also supported in a similar manner.

Rings 98 are fixed to these drive shafts 92 and 94 at a predetermined distance in the axially intermediate portion thereof. these rings 9
8 is a through hole 22F formed in the fixed carrier base 22
through which it is exposed to the top surface of the fixed carrier base 22. The outer circumferential surface of this ring 98 is flush with the surface of the film guide surface 22A or protrudes by a slight amount.

Furthermore, as shown in FIG.
2 to produce a film driving force.

(Description of Pressure Roller) Pressure roller shafts 110 and 112 are arranged on the upstream and downstream sides of the optical axis P in correspondence with the drive shafts 92 and 94, and pressure rollers 111 and 113 are arranged on both ends of these shafts in the axial direction. supported. These pressure rollers 111, 113 are connected to the drive shaft 9
The film F is sandwiched between the ring 98 of 2.94 and a driving force is generated to the film F in the six directions of the arrows.

Small diameter Taber rollers IIIA and 113A are pivotally supported between these pressure rollers 111 and 113 to position the pressure rollers without contacting the film F.

Both ends of these pressure roller shafts 110 and 112 are supported by rotating brackets 114 and 116, respectively, and are arranged so that their axes are horizontal with the pressure rollers 111 and 113 in contact with the ring 98. . These pivot brackets 114, 116 are pivoted to fixed brackets 122, 124 by pins 118, 120, respectively. These fixing brackets 122 and 124 are attached to the leg plate 122 in a U-shape with an open bottom as shown in FIG.
A, 122B and leg plates 124A, 124B are extended,
The tips of the leg plates 122B and 124B are attached to the mounting plate 1 in the horizontal direction.
26 is extended and fixed to the stationary carrier base 22 with screws 128 to form a cantilevered arm shape. These fixed brackets 122.124 are the pivot brackets 114.1
A torsion coil spring 130 is interposed between the ring 98 and the ring 98, thereby generating a biasing force that presses the pressure rollers 111, 113 against the ring 98.

(Description of Film Guide Means) A guide plate 140 that forms a narrow film guide space between it and the fixed carrier base 22 is arranged further downstream of the pressure roller 112. As shown in FIG. 2, the upstream end of this guide plate 140 is located on the opposite side of the optical axis P through the suppression roller 113 and slightly apart from the film guide surface 22A, and the downstream end is located on the opposite side of the optical axis P. is the lifting bracket 1
42.

Leg plates 142A erected from both sides of the elevating bracket 142 are pivotally supported by horizontal pins 144 to brackets 145 of the fixed carrier base 22. This horizontal pin 14
4 has an axis parallel to the direction of arrow A, and the biasing force of a torsion coil spring 146 attached to the outer periphery provides biasing force in the direction in which the guide plate 140 approaches the film guide surface 22A. However, this guide plate 140 is arranged so as not to come into contact with the film guide surface 22A.

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

As shown in FIG. 2, a fixed guide plate 150 is attached to the upstream side of the pressure roller 111 via an arm 148 to a fixed bracket 122, and similarly forms a guide space between it and the film guide surface 22A. The film F is guided to 111.

(Description of the barcode reading section) A barcode reading section 160 is provided upstream of the suppression roller 111.
is provided. This barcode reading section 160 is the fifth
As shown in the figure, a housing 162 is pivotally supported by a bracket 164 and a pin 166 that protrude from the fixed carrier base 22. The axis of this pin 166 is arranged parallel to the direction of arrow A, and is pressed against the film F passing through the housing 162 by the biasing force of a 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. Similar to the torsion coil spring 68, this torsion coil spring 158 has a coil portion that also functions as a compression coil spring, and presses the housing 162 to the right in FIG. Positioning in the direction of arrow A is also performed.

A pressing arm 172 is pivotally supported within the housing 162 by a pair of pins 170 parallel to the direction of the arrow. These pressing arms 172 are pushed against the opposing surface 172 by the biasing force of a compression coil spring 174 interposed between them and the housing 162.
A is pressed against both ends of the film F in the width direction with a light urging force, and moves to follow the ends of the film F in the width direction.

Therefore, the sensor 1 fixed to these pressing arms 172
The bar code 76 is always disposed at a predetermined distance from the end surface of the film F in the width direction, so that a bar code as a side print formed at a specific position from the end surface of the film F in the width direction can be appropriately read. This barcode records the film type, frame number, etc.

In the housing 162, a pressing roller 178 is mounted on a leaf spring bracket (179) corresponding to the intermediate portion of the pair of sensors 176.
Corresponding thereto is a suppression roller 182 which is supported pivotally through a film guide plate 180 which contacts one side of the passing film F and forms an extension surface of the film guide surface 22A.

The pressure roller 178 and the pressure roller 182 are applied to the film F which receives the pressure force in the width direction from the pressure arm 172.
It has the role of holding down the center part in the width direction so that it does not bend.

A transparent glass 184 is attached to the film guide plate 180 in correspondence with the barcode recording section of the film F.
A light projecting means 186 is provided on the lower surface thereof. As shown in FIG. 12, this transparent glass 184 has a protrusion 180A formed in an approximately semicircular shape that enlarges the widthwise dimension of the film guide plate 180. This is because the barcode formed on the film F is arranged very close to the widthwise end of the film F. Therefore, the suppression arm 172 is also formed with a recess 172B corresponding to the protrusion 180A and for accommodating the protrusion 180A.

As shown in FIG. 12, a detection arm 190 whose tip end is bent into an arc is provided on the upstream side of the pressing arm 172. This detection arm 190 generates an urging force that presses the end portion of the film F in the width direction. For this reason, if the film F is a long negative film made by connecting short negative films and there is a notch formed in advance corresponding to the connecting part, the film will enter the notch and activate the limit switch 192. and energizes the solenoid 194 provided in the housing 162 to separate the pressing arms 172 from each other, so that this film connecting portion is connected to the pressing arms 172.
This is to prevent feeding defects due to each contact with the opposing surface 172A.

A reflective sensor 196 is also provided to perform the same role as the detection arm 190.

This reflective sensor 196 detects a reflective part such as an identification tape applied in advance to a film joint, or detects a change in the amount of light transmitted through an adhesive tape part, and similarly operates a solenoid 194.

(Description of Interlocking Mechanism) An interlocking mechanism is provided that opens the film path by manually operating the pressure rollers 111, 113, guide plate 140, and barcode reading section 160.

This interlocking mechanism has an operating shaft 212 whose axis is arranged parallel to the direction of arrow C to the fixed bracket 124. The operating shaft 212 has a front end protruding from the leg plate 124A, and an operating knob 214 is fixed thereto. Further, the middle portion of the operating shaft 212 is a cutout plane portion 212A, which corresponds to the lower surface of the rotation bracket 116. That is, when the operating shaft 212 has its notched flat portion 212A corresponding to the lower surface of the rotating bracket 116, the pressing roller 113 can contact the ring 98, and the operating knob 214 is rotated in the direction of arrow F in FIG. Then, the outer peripheral surface of the operating shaft 212 twists the rotation bracket 116 around the pin 120 and causes the coil spring 130 to twist.
The pressing roller 113 is rotated against the urging force of the ring 9.
It is designed to be separated from 8.

One end of a link 218 is fixed to the tip of the operating shaft 212 protruding from the leg plate 124A. this link 218
The pin 220 protruding from the tip of the slide lever 22
It is connected to the second arm 224. This slide lever 222 is connected to the fixed carrier base 22 as shown in FIG.
It has an elongated hole 228 through which a pin 226 disposed upwardly and protruding from the fixed carrier base 22 passes. The axis of this long hole 228 is parallel to the direction of arrow A.

Therefore, when the operating knob 214 is rotated in the direction of arrow F, the slide lever 222 is slid in the direction of arrow G in FIG.

A pair of leg plates 230 are integrally projected from the downstream end of the slide lever 222 in the film transport direction, and a roller 232 is held by a pin 234. This roller 232
is the swash plate cam 1 formed at the end of the lifting bracket 142.
It corresponds to 42B. Therefore, when the slide lever 222 is moved in the direction of arrow G, this roller 232 presses the swash plate cam 142B downward, so that the elevating bracket 142
The guide plate 140 is rotated about the horizontal pin 144 against the biasing force of the torsion coil spring 146.
0 and the film guide surface 22A to form a large open space.

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 this link 240 is fixed to the end of a rotating shaft 242. This rotation shaft 242 is connected to the leg plates 122A, 12
2B, the shaft center of which is parallel to the direction of arrow C, and similarly to the operation shaft 212, a notched flat portion 242A is formed and corresponds to the lower surface of the rotation bracket 114. Therefore, this cutout plane portion 242A allows the pressing roller 111 to come into contact with the ring 98 when it corresponds to the rotating bracket 114, but when the slide lever 222 is driven in the direction of arrow G, the outer circumferential surface of the rotating shaft 242 corresponds to the rotating bracket 114, the rotating bracket 114 is rotated around the pin 1180, and the pressing roller 111 is rotated around the ring 9.
It is now separated by 8.

An arm 246 is fixed to the tip of the rotating shaft 242 protruding from the leg plate 122A. The tip of this arm 246 corresponds to the arm 162B protruding from the housing 162, and when the slide lever 222 is moved in the direction of arrow G, the arm 162B is pushed up and the housing 162 is pushed up.
2 is rotated around the pin 166 and separated from the film F.

(Function of the embodiment) In order to mount this film carrier 10 on a printing device,
Depending 824 of cover plate 24 as shown in FIG.
Since the base block 12 can be inserted into the base block A while being guided, the insertion work is extremely simple. Further, the base plate 14 is accurately positioned to the optical axis P by the positioning pins 18 and the positioning holes 20, and the film carrier is mounted on the support base 16.

When loading the film F, it may be inserted from either the six directions of arrows or the direction of arrow C. When inserting the film F from the direction of arrow A, the pressure rollers 111, 113 can be left in contact with the rings 98 of the drive shafts 92, 94, respectively. However, the barcode reading section 160
Pressure arm 172 is preferably held open by actuating solenoid 194.

When loading film F from the six directions of the arrows in this way,
Even if the tip of the film F is curled downward or upward, the gap S between the lower mask 30 and the recess 22B
Since the longitudinal direction of the film F is shifted from the film width direction and the chamfers 22C, 122D, 30A, and 30B are formed, the film F can smoothly slide on the film guide surface 22A and the lower mask 30.

When inserting film F from the direction of arrow C, the operating knob 214 is rotated in the direction of arrow F. As a result, the operating shaft 212 rotates the rotating bracket 116, so the pressing roller 113 separates from the ring 98 and rises, and the rotating shaft 242, which receives the driving force of the operating knob 214 via the slide lever 222, pushes up the rotating bracket 114. Therefore, the pressing roller 111 also separates from the ring 98 to widen the film guide path.

Further, as 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, so that the guide plate 140 is also largely separated from the film guide surface 22A. Furthermore, since the arm 162B of the barcode reading section 160 receives the rotational force of the rotating shaft 242 and rises, the film guide path is wide open.

Therefore, the film F can be easily inserted from the direction of arrow C. In this case, since the upper microphone 32 is raised by an angle θ1 due to the biasing force of the torsion coil spring 68, the film guide path of the mask body 40 is similarly left wide open. Further, the rotation lever 74 may be rotated to raise the upper mask 32 to the upper limit of the angle θ2 in FIG. 3.

After inserting the film F until it aligns with the optical axis P, return the operating knob 214 to its original position, and the rotating bracket 114.
Since the notched flat portion 242A and the notched flat portion 212A correspond to the rotating brackets 114 and 116, the pressing rollers 111 and 113 are respectively pressed against the ring 98 by the biasing force of the torsion coil spring 130, thereby sandwiching the film F. Along with this, the guide plate 140 also has a torsion coil spring 146.
The biasing force lowers the film to the state shown in FIG. 2, thereby forming a film guide path between the film guide surface 22A and the film guide surface 22A.

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

Here, the film F is moved in the direction of the arrow to align a predetermined image with the optical axis P.

During printing, when the upper mask 32 is lowered by driving the solenoid 78, the mask body 40 presses the film F against the lower mask 30, and the periphery of the printed image is pinched, making the printed image in a flat state, preventing printing from a light source (not shown). A photosensitive material (not shown) is printed using light.

In this way, when the upper mask 32 is lowered by the biasing force of the solenoid 78, the lowering operation of the rotary bracket 54 is stopped by the resin block 80 coming into contact with the rubber 84, so that unnecessary driving force is removed from the mask. No noise is applied to the main body 40, and there is no noise when stopped.

Thereafter, another image frame is printed on the film F in correspondence with the optical axis P, but the printing operation is the same as described above. When feeding the film F, the ring 98 is rotated by driving the motor 100 to enable rapid feeding.

Furthermore, when replacing the upper mask 32, by rotating the rotary lever 74, the notch 7OB is made to correspond to the protrusion 54B, and the upper mask 32 is raised by an angle θ2 due to the biasing force of the torsion coil spring 68. The upper mask 32 can be pulled out and inspected, or replaced with another upper mask 32. Also, when replacing the lower mask 30, the operation is convenient if the upper mask 32 is raised significantly.

When replacing the mask body 48 and holder 48 of the upper mask 32, the holder 48 is pulled out from the rotation bracket 54. New holder 4 with another mask body 48 attached
By inserting a predetermined amount into the recess 60A, the arm 6
The holder 48 is positioned by the balls 66 of No. 4 entering into the grooves 48B.

The barcode reading section 160 rotates the drive shafts 92 and 94 by the driving force of the motor 100, and is used when printing a plurality of image frames on a long film continuously. That is, the pressing arm 172 lightly presses both ends of the film F to accurately align the sensor 176 to the barcode recording position on the film F. Even if the tracking position of this sensor 176 changes slightly, it becomes impossible to read the barcode. - For boat fishing, this deviation must be 0.1 mm or less.

Therefore, bar codes such as the film type and frame number recorded on the film F can be read appropriately, and the printing conditions can be changed or the printed image frames can be recorded.

After the film F has passed, the opposing surface 172A of the pressing arm 172 of the barcode reading unit 160 is pressed against both sides of the film guide plate 1800 by the biasing force of the compression coil spring 174, so the opposing distance is determined by the width of the film F. than 0.
It becomes narrower by about 2 mm, and when the next film F is inserted, the rigidity of the film F causes it to expand a little again to accommodate both sides of the film F.

In addition, when multiple films are connected, the connecting splice part is connected to the detection arm 190 or the reflective sensor 196.
When detected, the solenoid 194 is energized, and the pressing arm 172 is temporarily separated from the end surface of the film F in the width direction. This prevents the pressing arm 172 from catching on the splice and interfering with film feeding.

In the above embodiment, the fixed guide plate 1 on the upstream side of the optical axis
50 may be moved up and down in the same way as the guide plate 140 on the downstream side of the optical axis.

〔Effect of the invention〕

As explained above, the present invention includes a side print reading sensor that is pressed toward both ends in the width direction of the film being conveyed toward the printing section, and a clamping device that clamps the middle part of the film in the width direction to prevent the film from warping. Since it has the means, it has an excellent effect of being able to accurately read the side print displayed at a predetermined position from the widthwise end of the film.
