Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Use of the Invention] The present invention is used in a film front / back determination measuring device, an automatic printer device, or the like for a slide in which a developed film is loaded in a mount, and the slide is set at a predetermined position. The present invention relates to a slide positioning device that crimps and positions a conveyance path.

[Background Art] In the film front / back determination device and the automatic printer device,
The slide is conveyed by sandwiching the side end surface of the slide between a driving roller and a press roller arranged along both sides of the conveying path. Then, a film front / back determination device, a printing device, etc. are arranged in the middle of the transportation path so that the transported slides are sequentially processed.

However, the shapes of the rollers and slides are not completely symmetrical, or the slide receives an asymmetrical force from the roller peripheral surface due to the axial misalignment of the roller, etc., and the slide may tilt with respect to the conveying road surface. In such a case, it is not possible to accurately determine the front and back of the film and to perform printing.

Therefore, it is necessary to provide a positioning device at the film front / back determination position, the printing position, etc. to position the slide.

However, when the slide is simply pressed against the conveying path, an unreasonable force is applied to the roller peripheral surface of the drive roller or the press roller or the slide, which causes abrasion of the roller peripheral surface or deformation of the slide. .

[Object of the Invention] In consideration of the above facts, the present invention makes it possible to press the slide at a predetermined position onto the conveying path, prevent wear of the roller peripheral surfaces of the drive roller and the press roller, and deform the slide. It is an object of the present invention to obtain a slide positioning device which does not exist.

[Configuration of the Invention] To achieve the above object, the present invention is a slide positioning device for positioning a slide at a predetermined position of a conveyance path for conveying a slide, wherein a shaft is provided on one side of the predetermined position with a conveyance path surface. A first roller so as to be orthogonal to the first roller, and a second roller on the other side of the predetermined position, the shaft being orthogonal to the conveyance road surface and being capable of approaching and separating from the first roller. A roller and a biasing means for biasing the second roller so as to approach the first roller so that the slide is sandwiched between the first roller and the second roller. A pressure-bonding means for pressing a slide sandwiched between the first roller and the second roller to pressure-bond it to the conveyance path surface;
Separating means for separating the roller of from the slide side end surface,
It is configured to include.

In the present invention, the first roller is arranged on one side of the transport path and the second roller is arranged on the other side. The second roller is capable of approaching and separating from the first roller, and the second roller is biased by the biasing means so as to approach the first roller. Therefore, the slide sandwiched between the first roller and the second roller is pushed toward the first roller by the biasing means. The slide sandwiched between the first roller and the second roller is pressed by the pressure bonding means and pressure-bonded to the conveyance path surface. At this time, the separating means separates the second roller from the slide side end surface in conjunction with the operation of the pressure bonding means. Even if the slide is clamped in a state of being inclined with respect to the conveyance path surface, the second roller is separated from the slide-side end surface against the urging force of the urging means by the separating means, so the slide is deformed by the crimping means. It can be pressure-bonded to the transporting road surface without causing it. By crimping the slide onto the transport path surface, the slide can be positioned in a direction orthogonal to the transport path surface.

The roller 62 has a retaining ring 64 attached to the upper end of the shaft 60 to prevent the roller 62 from moving in the direction of the shaft 60. The other end of the arm 56 is locked to the fixed portion 68 via a tension coil spring 66. Therefore, arm 56 is pin 5
Around 8 is urged counterclockwise in FIG. A protrusion 70 is provided on the side surface of the carrier 42,
The movement amount of the arm 56 in the counterclockwise direction in FIG. 2 is limited corresponding to the peripheral surface of the shaft 60. The surface of the carrier table 42 constitutes a carrier path 72, and the slide 20 is mounted therein. The slide 20 has rollers 5 on both sides thereof.
It is sandwiched between the roller 2 and the roller 62, and when the driving unit 54 rotates the roller 52, the slide 20 is conveyed. The peripheral surfaces of the rollers 52 and 62 are tapered, and the radius of their lower ends is smaller than the radius of their upper ends.

Therefore, the slide 20 receives the force from the rollers 52 and 62 in the downward direction in FIG. 3, and does not fly out above the rollers 52 and 62.

As shown in FIG. 4, the rollers 52 and 62 have the same effect as described above even if only the peripheral surface of the roller upper end portion is tapered. Further, in FIG. 4, the transport path 72 has a concave shape so that the contact area with the mount 74 is narrowed and the film 76 is sufficiently separated from the transport path to prevent the film from being damaged.

As shown in FIG. 1, when the slide 20 is inserted into the delivery port 26, an optical sensor (not shown) rotates the receiving portion 36 and the drive roller 44 of the turntable 38 to convey the slide 20 onto the turntable 38. It When the slide 20 is mounted on the turntable 38, the receiver 36 and the turntable 3 are driven by an optical sensor (not shown).

When the film state measuring device 78 determines that the front and back of the film are normal, the slide 20 is further conveyed to the magazine 34 side, and the slide device 20 stores the slide 20 in the magazine 34. The magazine 34 is moved up and down by a magazine driving device 84 provided in the photoprinting preparation device 10, and the inside thereof is rotated to be sequentially stored in a large number of slide storage chambers (not shown).

The magazine 34 is provided with a memory device (not shown). When the process of storing the slide 20 in the magazine 34 is completed, the correction values of the color correction and the density correction input by the keyboard 28 and the data of the film mounting position measured by the film state measuring device 78 are transferred to the memory device. It is like this. Then magazine 3
4 is detached from the magazine drive device 84 and attached to a printer device (not shown).

The film state measuring device 78 measures the distance from the reference plane of the film 76 by using an optical pickup 86 provided below the conveying path 72. The optical pickup 86 is, for example, Olympus Taos (trade name) or the like. In this embodiment, the objective lens in the optical pickup 86 is fixed with an adhesive so that the objective lens does not vibrate with respect to the case of the optical pickup 86.
The objective lens may be electromagnetically fixed to the case of the optical pickup by supplying a relatively large constant current to the coil of the objective lens actuator. The optical pickup 86 is attached to the frame 88. The frame 88 is provided with a screw hole 90,
The shaft 92 is screwed to this. A spur gear 94 is attached to the lower end of the shaft 92.
The spur gear 94 meshes with a spur gear 98 fixed to the shaft of the pulse motor 96. Therefore, when the pulse motor 96 is rotated, the shaft 92 is rotated via the spur gears 98 and 94, and the optical pickup 86 is moved up and down. A panel generator 100 is attached to the spur gear 98 so as to detect the vertical position of the optical pickup 86. The lower limit position of the optical pickup 86 is detected by the limit switch 102.

A bracket 106 is erected on the base 104,
A shaft 110 protruding from one end of the crimp arm 108 is supported. An opening 112 is provided at the other end of the crimp arm 108. A pin 114 having a head is loosely inserted around the opening 112. The lower end of the pin 114 is fixed to the crimping plate 116. Crimping arm 108
A compression coil spring 118 is provided coaxially with the pin 114 between the and compression plate 116. Therefore, axis 1
When the crimping arm 108 is rotated in the clockwise direction in FIG. 5 around the center 10, the crimping plate 116 elastically presses the slide 20 and the mount 74 can be crimped to the transport path 72. A pin 120 having a head is loosely inserted in the middle of the crimping arm 108, and the lower end of the pin 120 is fixed to the base 104. A compression coil spring 122 is interposed between the crimp arm 108 and the base 104 coaxially with the pin 120.
A solenoid 124 is fixed to the base 104 located between the pin 120 and the shaft 110. Solenoid 12
Plunger 126 with heads aspirated at 4,
The elongated hole 128 formed in the crimping arm 108 is loosely penetrated. Therefore, the solenoid 124 causes the plunger 126 to
Is sucked, the crimping arm 108 resists the urging force of the compression coil spring 122, and the crimping arm 108 moves about the shaft 110 at the fifth position.
It is designed to rotate clockwise. When the solenoid 124 is demagnetized, the compression coil spring 1
The pressure bonding arm 108 is automatically returned by 22.

The drive roller 44 and the press roller 46, which are similar to those described above, are disposed on both sides of the transport path 72 so as to face each other. A pin 130 is projectingly provided on the peripheral surface of the shaft 60 of the press roller 46. A U-shaped engagement arm 134 is attached to the tip of the pin 130 via a rubber coupling ring 132. On the other hand, brackets 136 and 138 are provided on the crimping arm 108 and the base 104 so as to face each other. These brackets 136 and 138 are the link bars 14
They are connected by 0 and 142. Link bar 140,
The rod 144 connecting the 142 corresponds to the tip of the engaging arm 134. When the solenoid 124 is demagnetized, the engagement arm 134 is separated from the rod 144, and the press roller 46 operates normally. When the solenoid 124 is excited, the engagement arm 134 is pressed to the left in FIG. 5 by the rod 144, and the roller 62 of the press roller 46 is separated from the side end surface of the mount 74.

Therefore, when the pressure-bonding plate 116 pressure-bonds the slide 20, even if the slide 20 is inclined with respect to the surface of the transport path 72, the roller 62 escapes from the slide 20 to perform pressure-bonding smoothly, and the roller 52 ,
It does not wear 62. In addition, this escape moves at a high speed with the crimping arm 108, so that there is no timing deviation with the crimping arm 108. Also, the engagement arm 1
Reference numeral 34 is not orthogonal to the rod 144, and the frictional resistance between the two is reduced so that the escape can be performed smoothly.

The crimping plate 116 has a shape similar to that of the slide 20, and a glass 146 is attached instead of the film 76. A circular rubber plate 1 is provided at the center of the glass 146.
48 is attached. This rubber plate 148 is for preventing light from entering the inside of the optical pickup 86 from the outside. The glass 146 is located below the opening 112. A dome 152 is provided on the cover 150 above the opening 112. The dome 152 is a parabolic mirror, and a heating lamp (not shown) is provided inside. When this heat lamp is turned on, its radiant heat reaches the film 76 through the opening 112 and the glass 146. As shown in FIG. 7, the film 76 has an emulsion layer 76B laminated on a film base layer 76A. When the film 76 is heated, the water content of the emulsion layer 76B decreases, and the emulsion layer 76B contracts relative to the base layer 76A and curls to the state shown in FIG. 7 (B). Therefore, the front and back of the film can be determined by detecting the direction of this curl by the optical pickup 86.

Next, the film state measuring device 154 will be described with reference to FIG.

The laser light emitted by the optical pickup 86 and reflected by the film 76 is divided into four photodiodes 15
6, 158, 160, 162. The signals received by the photodiodes 156 and 158 are added by the adder 164 and input to the non-inverting terminal of the comparator 166. The signals received by the photodiodes 160 and 162 are added by the adder 168 and input to the inverting terminal of the comparator 166. The output signal of the comparator 166, that is, the focus error is passed through the low-pass filter 169 and the A / D converter 170 to the microcomputer 1
It is adapted to be input to the input interface 174 of 72. The low-pass filter 169 is for removing low-frequency noise due to mechanical vibration. The micro computer 172 uses the input interface 174.
Besides, CPU (Central Processing Unit) 17
6, ROM (Read Only Memory) 178, RAM (Random Access Memory) 180, Output Interface 1
82 and a bus 184 for connecting them.

The signals from the pulse generator 100, the limit switch 102, the pressure-compression completion signal, and the calibration signal are input to the input interface 174. The pulse generator 100 outputs two types of pulse signals that are 90 degrees out of phase with each other, and can detect forward rotation or reverse rotation. In addition, the pulse motor 9 is used without using the pulse generator 100.
The position of the optical pick-up 86 may be obtained by a pulse signal to the optical disc 6.

The output interface 182 outputs a signal to the pulse motor 96 and the heat generating lamp 188 and a roller driving signal. The pulse generator 10
The signal from 0 is an interrupt signal to the CPU 176.

Next, the flow charts shown in FIGS. 9 to 11 corresponding to the programs stored in the ROM 178 will be described.

If the crimp completion signal is on (step 200) and the calibration signal is off (step 20).
2) The film position and curl are measured (step 204) That is, as shown in FIG. 10, the pulse motor 96 is rotated in the forward direction to raise the optical pick-up 86 (step 30).
2). Next, it is judged whether or not the focus error is the peak point X (see FIG. 13) (step 304).

When the optical pickup 86 is moved up and down, the CPU 176 is interrupted by the pulse signal from the pulse generator 100, and the interrupt processing shown in FIG. 11 is executed. That is, it is determined whether the optical pick-up 86 is rising or falling (step 402), and if it is rising, the value of the counter C is incremented (step 40).
4). If it is descending, the value of the counter C is decremented (step 406). Therefore, the amount of increase or decrease of the optical pickup 86 can be known from the value of the counter C. The position (initial position) of the optical pick-up 86 when the value of the counter C becomes 0 is the optical pick-up 8 when the film is at the position of the reference plane 194, as will be described later in the calibration.
This is the position when zero focus error is detected by 6.

When the focus error peak point X is detected, the value of the counter C is stored in P. (Step 306). When the optical pickup 86 further rises and zero focus error is detected (step 308), the value of C is stored in Q. The value of Q is the distance from the reference surface 194 to the film.
Next, (P + Q) / 2 is obtained and stored in R (step 310). As shown in FIG. 13, the value of R is a halfway intermediate position between the focus error peak point and the focus error zero point, and the change amount of the focus error is a sharp point. That is, it is a position where the focus error responds sensitively to the curl due to the film heating, and this position is the curl measurement position of the optical pick-up 86.

Next, the pulse motor 96 is rotated in the reverse direction so that the optical pickup 8
6 is lowered (step 312), and when the value of the counter C becomes equal to R (step 314), the pulse motor 96
To stop. Then, the focus error at this point is read from the A / D converter 170, and this value is stored in E ₁ . Further, the heat lamp 188 is turned on to heat the film 76 (step 316). Next, a soft timer waits for 3 seconds (step 318). Then, the focus error after heating the film 76 is read from the A / D converter 170, this value is stored in E ₂ , and the heat lamp 188 is turned off (step 320). Next, the pulse motor 96 is rotated in the reverse direction (step 322) and the counter C
When the value of 0 becomes 0 (step 324), the pulse motor 96 is stopped (step 326). In this way, the optical pickup 86 returns to the initial position and the film position measuring process is completed.

Next, at step 206 in FIG. 9, the values of E ₁ and E ₂ which are the focus errors before and after the film heating are compared to determine the branch destination.

When E ₁ > E ₂ , that is, when the film 76 is face-up, in step 208, the drive roller 44 is normally rotated to convey the slide 20 to the magazine 34 side, and at the same time, the value of Q is transferred to the memory device in the magazine 34. To do. Further, the turntable 38 is rotated to the state shown in FIG. 1 to prepare for the next slide. When E ₁ <E ₂ , that is, when the film is face down, in step 210, the buzzer is rung, the driving roller 44 is reversed, and the slide 20 is conveyed to the discharge port 80.

The optical pick-up 86 curl measurement position may be a position other than the point R shown in FIG.

At the start of work by the photoprinting preparation apparatus 10 (before slide conveyance), the solenoid 124 is excited and a calibration signal is input to the input interface 174, and the pulse motor 96 is rotated in the reverse direction (step 22).
2). When the optical pickup 86 descends and the limit switch 102 operates (step 224), the pulse motor 9
6 is rotated in the normal direction to raise the optical pickup 86 (step 226). When the focus error zero is detected by the signal from the A / D converter 170 (step 228), the value of the counter C is made equal to the value of H written in the ROM 178 (step 230). Next, the processing from step 322 to step 326 in FIG. 10 is performed, and the optical pickup 86 is stopped at the position where the value of the counter C becomes 0 (step 232). The calibration is completed by the above processing, and the process returns to step 200.

As described above, the front and back of the film can be judged and the calibration can be performed very easily.

The curl amount due to the heating of the film is about 10 μm, and when the vibration is transmitted to the film state measuring device 78, that is, when the film 76 vibrates relatively to the optical pickup 86, the front and back of the film can be accurately determined. Can not be. However, the operator's keyboard 28
The operation and processing on the shear caster 18 serve as a vibration source. Also, the low-pass filter 169 cannot completely remove low-frequency noise. Therefore, as shown in FIG. 1, the automatic processing unit 16 is separated from the manual processing unit 14, and the automatic processing unit 16 is attached to the bottom surface of the case 12 via a vibration-proof rubber 196. The inertia of the automatic processing unit 16 is sufficiently large, and the resonance frequency of the system including the automatic processing unit 16 and the anti-vibration rubber 196 is sufficiently lower than the resonance frequency of the other integrated portions. . Therefore, it is difficult for vibration of an undesired frequency to be transmitted to the automatic processing unit 16, and it is possible to perform accurate front / back determination.
At the time of the front / back determination, the drive roller 44 is stopped and the vibration from the drive roller 44 can be ignored.

[Effect of the Invention] As described above, according to the present invention, the first roller and the second roller can be brought into contact with and separated from each other and urged in a direction to approach each other.
The second roller is separated from the end surface on the slide side, and
Since the slide sandwiched between the second roller and the second roller is pressed and pressure-bonded to the conveyance path surface, it is possible to perform the positioning in the direction orthogonal to the conveyance path surface without deforming the slide. To be
