Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographic film processing apparatus, and more specifically, to a mounting table on which a photographic film can be mounted, and a means for irradiating the photographic film on the mounting table from below, A film cutting means for cutting the photographic film on the mounting table into pieces, a film inserter for inserting the piece-shaped film cut by the cutting means into each negative piece insertion pocket of a long negative sheet, and a predetermined number of pieces Negative film cutting means for separating the negative sheet portion containing the film-like film from the long negative sheet, the film inserter includes a conveying means for feeding the long negative sheet toward an appropriate position located downstream of the piece-like film. The present invention relates to an apparatus for processing photographic film.

[0002]

2. Description of the Related Art In a photographic film processing apparatus according to the prior art described above, a transparent portion as a boundary between image frames formed on a photographic film mounted on a mounting table is irradiated from below by an irradiating means. In this state, it can be cut into pieces (having a length of six frames in this case) after being aligned with the cutting means. Further, the cut piece-shaped film is inserted into each negative piece insertion pocket portion of the long negative sheet by a film inserter, while the long negative sheet is successively directed to an appropriate position located downstream of the piece-shaped film. It is configured to be sent by the transport means. As a result, the operator operating the photographic film processing apparatus can usually concentrate on the work of aligning the blank portion with the cutting means, and when all the one roll film has been cut into pieces, By operating the negative sheet cutting means, the negative sheet can be separated from the long negative sheet in a separation area where the negative piece insertion pockets of the negative sheet are connected to each other.

By the way, in the above-mentioned configuration, a corresponding empty negative piece insertion pocket portion of the long negative sheet is placed at an appropriate position downstream of the piece-like film irrespective of the operation of the conveying means due to slippage or jamming of the negative sheet. Abnormal conditions that are not located can also occur. If the operator operates the negative sheet cutting means without noticing such an abnormal state, there is a possibility that the negative sheet is cut not in the correct cutting area but in the area of the negative piece insertion pocket portion. Thus, in such an abnormal state, an example of a photographic film processing apparatus provided with a control mechanism that does not execute cutting even when the operator turns on the negative sheet cutting means is disclosed in Japanese Patent Application No. 11-11894 filed by the present applicant. Has been proposed. In the content of this application, it is proposed to provide a control mechanism for preventing the operation of the film insertion mechanism and the cutting mechanism when the determination means for determining the stop position of the negative sheet recognizes that the negative sheet has not stopped at the set position. Have been.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a long negative sheet with an operator in an abnormal state where the corresponding pocket for inserting a negative piece is not located at the proper position regardless of the operation of the conveying means. Means for preventing the negative sheet cutting operation is to be provided in a form different from the control mechanism for preventing the operation of the film insertion mechanism and the cutting mechanism described in the above-described prior art photographic film processing apparatus. .

[0005]

According to a first aspect of the present invention, there is provided a cutting apparatus for a photographic film, comprising: detecting means for detecting coincidence of the negative piece insertion pocket with the proper position. Warning means for issuing a warning to an operator when the coincidence is not detected irrespective of the operation of the transport means for feeding the long negative sheet, wherein the warning means is provided for the photographic film by the irradiation means. It is characterized by comprising means for changing the irradiation state.

[0006] In order to have such a characteristic configuration,
In the photographic film processing apparatus according to claim 1 of the present invention,
It is possible to provide a warning means for giving a warning to an operator in an abnormal state where the coincidence is not detected irrespective of the operation of the conveying means for feeding the long negative sheet, in a form in which the existing member called the irradiation means is effectively used. Was. Also,
Workers pay attention to the photographic film present under their eyes as an important product received from customers when contacting the photographic film processing device, so do not overlook the change in the irradiation state of this photographic film, An abnormal condition can be surely noticed. Furthermore, as an auxiliary means for accurately aligning the transparent portion formed on the photographic film with the cutting means, a change in the state of the irradiation means that the operator has been familiar with conventionally requires a new warning lamp or the like. Compared to the case of additional installation, it is easier to appeal to the operator's intuition (as an occurrence of an abnormality), so that the operator can more reliably deter the switch operation of the negative sheet cutting means.

As a specific configuration, the warning means includes:
The light amount of the light source constituting the irradiation means can be changed repeatedly. Specifically, for example, it is possible to adopt a configuration in which a state in which the state changes at intervals of several seconds between a high luminance state in which the light amount is increased by 20% and a low luminance state in which the light amount is small by 20% is continued.

In particular, the light source may be turned on and off (at intervals of several seconds, for example). Thereby, the operator can be more clearly notified of the abnormal state.

[0009] Alternatively, as a specific configuration, the warning means may be capable of changing the direction of a light source constituting the irradiation means. For example, in a normal state (that is, a state in which the long negative sheet is arranged at an appropriate position by the conveying means), the center of the light from the light source illuminates the cutting portion. Can be configured to rotate around a vertical axis or a horizontal axis.

[0010] In still another specific configuration, the warning means may be capable of repeatedly changing the wavelength of light illuminating the photographic film.

In particular, the irradiating means may include a plurality of light sources having different emission colors, and the warning means may alternately blink the plurality of light sources having different emission colors.

[0012] Other features and advantages of the invention include:
The description will become apparent from the description of the embodiment using the drawings.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. The photographic film processing apparatus, shown generally in FIGS. 1-3, is adjacent to a processor (not shown) that develops the photographic film and exposes the photographic film to photographic paper based on the developed photographic film to create a silver halide print. It is more effective if they are arranged and used. This photographic film processing apparatus converts a long photographic film F into a short negative piece P
(A film having images for six frames in principle), and an enveloper section for storing the negative piece P cut by the cutter section 1 in a negative sheet 40 made of resin and provided with many negative piece insertion pockets 40p. Consists of two.

(Structure of Cutter Unit) As shown in FIG. 3, the cutter unit 1 supports a long photographic film F supplied in the direction of an arrow from the processor (an example of the upstream side). Acrylic upstream viewer plate 4 and upstream viewer plate 4 made of colorless and transparent acrylic placed almost horizontally
A cutter 10 for cutting the upper photographic film F,
A light source 8 for irradiating the photographic film (F or P) on the upstream viewer plate 4 from below. In this embodiment, the supply of the long photographic film F means an operation of manually placing an 35 mm film having 24 or 36 image frames on the upstream viewer plate 4 by an operator. As best shown in FIGS. 4 and 8, the cutter 10 comprises a lower blade 12 arranged upstream of the downstream end of the upstream viewer plate 4 (which coincides with the cutting line L0); The upper blade 14 is located on the downstream side of the lower blade 12 across the cutting line L0. The upper blade 14 is manually operated with respect to the fixed lower blade 12 via the swingable negative cut lever 15 shown in FIGS. 1 and 2 (that is, a manual operation of pushing down the negative cut lever 15 from the home position). Operation), the swing operation is performed. The boundary between the lower blade 12 and the upper blade 14 is configured to coincide with the cutting line L0.

As shown in FIG. 8, near the upstream end of the substantially horizontal lower surface 4 b of the upstream viewer plate 4,
There is an upstream end surface 4c extending vertically from the lower surface 4b, and the light source 8 is housed in a space 4s adjacent to the upstream side of the upstream end surface 4c. The light source 8 is composed of five light emitting diodes arranged substantially horizontally, and these light emitting diodes emit white light toward the upstream end face 4c of the upstream viewer plate 4 located on the downstream side. On the other hand, near the downstream end of the generally horizontal lower surface 4b of the upstream viewer plate 4 is a very short first end surface 4d extending vertically from the substantially horizontal upper surface 4a of the upstream viewer plate 4, and slightly from the lower surface 4b. It comprises a third end face 4f that extends obliquely to the downstream side, and a second end face 4e that connects the first end face 4d and the third end face 4f so as to be more inclined than the third end face 4f. Also, the lower blade 12 is
The end face 12a extending from the end face 4d to the second end face 4e and forming the edge of the lower blade 12 and the first end face 4d of the upstream viewer plate 4 coincide with each other in the photographic film supply direction, and they are cut. It also matches line L0.

Further, the reflecting member layer 6 is formed on the entire lower surface of the upstream viewer plate 4, that is, on the substantially horizontal lower surface 4b, the second end face 4e, and the third end face 4f. Here, the reflection member layer 6 is a coating film composed of white fine particles such as titanium oxide, zinc oxide, or alumina. If these fine particles are dispersed in a solvent composed of an appropriate resin and a dispersant and then applied to the lower surface of the upstream viewer plate 4, a large number of crystal planes extending in a random direction on these individual fine particles gather. Thus, an irregular reflection surface extending along the lower surface of the upstream viewer plate 4 is formed as a whole. The hue of the fine particles is not limited to white, but for the purpose of obtaining a high reflectance, those having relatively high brightness are preferable. The particle diameter of the fine particles may be appropriately selected from the range of several microns to several tens of microns (the weight of particles falling within each particle diameter range is almost normally distributed, and the maximum particle diameter is about 40 microns). The fine particles constituting the formed reflecting member layer 6 form an irregular reflection surface with the upstream viewer plate 4, and at the same time, the light rays that have once entered the cross section of the upstream viewer plate 4 are reflected by the upstream viewer plate 4. To escape to the outside through the lower surface of the. Therefore, some of the light rays emitted from the light source 8 and entering the cross section of the upstream viewer plate 4 are scattered in various directions by the irregular reflection surface, and the lower surface of the upstream viewer plate 4 (the upper surface of the reflection member layer 6). Is equivalent to a bright surface with substantially uniform brightness.

Therefore, most of the light rays emitted from the light source 8 are
After the light enters the cross section of the upstream viewer plate 4 from the upstream end face 4c of the upstream viewer plate 4 (where no reflection member layer is provided), the reflection member layer 6 on the substantially horizontal lower surface 4b is irradiated. While traveling substantially horizontally in the colorless and transparent acrylic material of the upstream viewer plate 4, the first end surface 4 d and the reflection member layer 6 on the second end surface 4 e near the downstream end of the upstream viewer plate 4. The light is reflected upward and illuminates the photographic film (F or P) on the cutting line of the upstream viewer plate 4 from below, passes through it, and finally reaches the eyes E of the operator. That is, as illustrated in FIG. 8, light rays emitted from the light source 8 and entering the cross section of the upstream viewer plate 4 form a shadow of the lower blade 12 on the surface of the upstream viewer plate 4 or the photographic film. The photographic film (F or P) directly reaches the first end surface 4d, which is the most downstream end surface of the upstream viewer plate 4, on the cutting line of the upstream viewer plate 4 on the downstream end surface of the viewer plate. ) With sufficient illumination. At the same time, light rays incident on the cross section of the upstream viewer plate 4 form a good luminous surface based on the reflection member layer 6. As a result, the operator who puts the eye E above the upstream viewer plate 4 can use a photographic film (F or P) irradiated with a sufficient amount of light while using the bright surface formed by the reflecting member layer 6 as a good background. Can be observed.

As best shown in FIGS. 5 and 6, on the upper surface 4a of the upstream viewer plate 4, a cutting line
The reference line L1 is used as a reference when placing the image frame within the boundary area between the image frames on the 5 mm photographic film.
L2 is graduated. The reference line L1 is a cutting line, that is, 3 lines from the downstream end of the upstream viewer plate 4.
This is a line segment drawn by 8 mm upstream, and the reference line L
Similarly, the reference numeral 2 is linearly drawn further 38 mm upstream from the reference line L1. Also, from the upper surface 4a of the upstream viewer plate 4, a pair of first and second pairs for accurately guiding the 35 mm photographic film F supplied from the upstream side.
The guide surfaces 16, 18 extend vertically. That is, the width between the pair of guide surfaces 16 and 18 is set to 35 mm.

As shown in FIG. 6, near the downstream end near the first guide surface 16, an upstream viewer plate 4 is provided.
Are provided with through-holes penetrating in the up-down direction, and transport rollers 20, 22 (see FIG. 8) for discharging the photographic film P on the upstream viewer plate 4 to the downstream side are provided here. . The upper conveying roller 20 is in contact with the outer peripheral portion of the lower conveying roller 22 at the same level as the photographic films F and P placed on the upper surface 4a of the upstream viewer plate 4, and The position can be switched between a standby position separated upward from the outer peripheral portion of the transport roller 22 on the side. The lower transport roller 22 is configured to be rotatable by a motor M1. The negative cut lever 15 is provided with a home position with respect to its swinging posture. When an operator lifts the negative cut lever 15 above the home position, a first sensor (not shown) changes the posture of the negative cut lever 15. Is detected, and the conveying roller 20 is detected based on the detection signal.
Is lowered to the operation position, and at the same time, the lower conveying roller 2
The controller 2 is configured so that the photographic film P on the upstream viewer plate 4 is fed to the downstream side, that is, into the pocket of the negative sheet set in the enveloper section 2, by starting the rotation operation of the photographic film P. The operator observes that the downstream end of the photographic film P has reached the bottom of the pocket of the negative sheet, and returns the negative cut lever 15 to the home position (to return to the home position by releasing the negative cut lever 15). It is configured).
When the negative cut lever 15 returns to the home position, the detection signal from the first sensor is interrupted, so that the rotation operation of the lower conveying roller 22 is stopped and the upper conveying roller 20 is stopped.
Rises to the standby position. At the same time that the downstream end of the photographic film P reaches the bottom of the pocket of the negative sheet,
At least the outer periphery of the transport roller 22 is made of a smooth stainless steel having a small friction coefficient so that the lower transport roller 22 starts idling with respect to the surface of the photographic film F. As described above, when the negative cut lever 15 is located at the home position, the photographic film F is released from the state in which the transport rollers 20 and 22 are pinched, and the operator manually moves the position of the photographic film F. , It is possible to easily adjust the blank portion located between the image frames of the photographic film F to the cutting position P0. When the operation of aligning the plain portion of the photographic film F with the cutting position P0 is completed, the operator can move the negative cut lever 15 downward from the home position to cut the photographic film F.

If the last negative piece (especially a shorter negative piece such as 5 frames or less) remaining in one order is not completely inserted into the negative insertion pocket of the negative sheet, the negative piece is removed from the negative insertion pocket. A manual insertion device, that is, an inserter 24, is provided as an assisting tool for pushing the device into the device. As shown in FIG. 4, the inserter 24 is connected to the upper surface 4 a of the upstream viewer plate 4 by a parallel link mechanism including two link members 28 a and 28 b.

And a push-in piece 26 that can reciprocate between an operation position (broken line in FIG. 4B) located downstream of the standby position in the photographic film supply direction with respect to the standby position. The pushing piece 26 is
Normally, it is held in the standby position by its own weight or an urging spring (not shown), and is switched to the operation position by tilting the handle member 30 to the arrow A. In the middle of the switching operation to the action posture, the downstream end of the push-in piece 26 is connected to the upstream viewer plate 4.
The photographic film P on the upstream viewer plate 4 is completely inserted into the pocket of the negative sheet while moving downward while emerging upward from the slit 4G formed in the negative sheet. The handle member 30 is swingably supported around the axis X. When the handle member 30 is tilted in the direction of arrow A, the disk member 3 fixed to the base end of the handle member 30 near the axis X
The upper operation pin 32a swings the link member 28b rightward in the drawing to switch the push-in piece 26 to the above-mentioned working posture. Reference numeral 34 written in FIG. 3 indicates that, when the central portion of the photographic film F has a swelling shape in the shape of a semi-cylindrical shape, the photographic film F is corrected to a flat state and then placed on a cutting line. It is a press roller supported so as to be freely rotatable for disposition. The pressing roller 34 is rotatably supported around a fixed axis, and the outer peripheral portion of the pressing roller 34 formed of an elastic material such as rubber presses the photographic films F and P against the upper surface 4 a of the upstream viewer plate 4. .

(Structure of Enveloper Unit) As shown in FIGS. 1 and 2, the enveloper unit 2 converts a negative sheet 40 accumulated in a roll form in a lower negative sheet stocker 42 into an upstream viewer plate 4 of the photographic film cutting apparatus 1. A pair of upper and lower sheet conveying rollers 44, 44 for pulling out to a position on the downstream side, a stepping motor M2 for rotationally driving at least one of the sheet conveying rollers 44, 44, and an opening for inserting the pulled out negative sheet 40 are enlarged.

And a sheet mark sensor 52 (see FIG. 3) for optically detecting a sheet mark printed near the bottom of each of the negative piece insertion pockets provided in the camera. When the position of one negative piece insertion pocket 40p coincides with the position (appropriate position) of the photographic films F and P on the upstream viewer plate 4, the sheet mark sensor 52 detects the negative piece insertion pocket 40p several steps downstream. And 4
It is arranged to detect a sheet mark 40a formed between the negative piece insertion pocket 40p on the downstream side of the step. Below the home position described in the configuration of the cutter unit, a second sensor 15a for detecting movement of the negative cut lever 15 to the bottom dead center is provided. That is,
When the operator presses down the negative cut lever 15 from its home position to the bottom dead center in order to cut the photographic film F, and then starts a return operation toward the home position, the negative cut lever 15 faces upward from the bottom dead center. Is detected by the second sensor 15a, and based on this detection signal, the controller drives the stepping motor M2 for the sheet conveying rollers 44, 44,
The negative sheet 40 is moved by one pitch (corresponding to the distance between the centers of adjacent pockets, and in this embodiment, about 50 pitches).
mm), and the negative sheet 40 is positioned so as to receive the next photographic film F. Therefore, unless abnormal slippage or jamming of the negative sheet 40 occurs between the sheet conveying rollers 44, 44 and the negative sheet 40, the motor M2 and the sheet conveying rollers 44, 44 are not used.
In each drive-stop operation, the negative sheet 40 is fed in from the downstream side, and a new sheet mark 40a comes just downstream of the sheet mark sensor 52 (the new negative insertion pocket is at the appropriate position). Will be.

If the piece-shaped negative sheet cannot be completely inserted into the negative piece insertion pocket, it is inserted into the negative piece insertion pocket of the negative sheet 40 as a manual insertion device, that is, an auxiliary inserter 24. Is provided. As shown in FIG.

State) and a push-in piece 26 that can reciprocate between an operation position (a broken line in FIG. 4B) located downstream of the standby position in the photographic film supply direction with respect to the standby position. The pushing piece 26 is normally held in the standby position by its own weight or by an urging spring (not shown), and is switched to the operating position by tilting the handle member 30 in the direction of the arrow A. In the middle of the switching operation to the working posture, the downstream end of the pushing piece 26 moves downstream while emerging upward from the slit 4G formed in the upstream viewer plate 4. Then, the photographic film P on the upstream viewer plate 4 is completely inserted into the pocket of the negative sheet.

The handle member 30 is swingably supported around an axis X. When the handle member 30 is tilted in the direction of arrow A, a disk member fixed to the base end of the handle member 30 near the axis X The operation pin 32a on the link member 2
8b is swung to the right in the figure to switch the pushing piece 26 to the above-mentioned working posture. Reference numeral 34 written in FIG. 3 indicates that, when the central portion of the photographic film F has a swelling shape in the shape of a semi-cylindrical shape, the photographic film F is corrected to a flat state and then placed on a cutting line. It is a press roller supported so as to be freely rotatable for disposition. Pressing roller 34
Is configured so as to be rotatable around a fixed axis, and to press the photographic films F and P against the upper surface 4a of the upstream viewer plate 4 with the outer peripheral portion of the pressing roller 34 formed of an elastic material such as rubber. Just do it. Alternatively, the photographic films F and P may be pressed against the upper surface 4a of the upstream viewer plate 4 by a biasing means such as a spring or by its own weight while being supported so as to be movable in the vertical direction. .

In the enveloper section 2, a downstream viewer plate on which the negative sheet 40 fed from the negative sheet stocker 42 by the sheet transport rollers 44, 44 can be placed together with the photographic film P stored in the negative piece insertion pocket of the negative sheet 40. 104 are provided.
As shown in FIGS. 7, 8 and 9, the downstream viewer plate 104 is made of the same material as the upstream viewer plate 4, that is, a colorless and transparent acrylic plate-shaped main body, and a reflection plate provided on the lower surface of the plate-shaped main body. And a member layer 106. Near the downstream end of the substantially horizontal lower surface 104b of the downstream viewer plate 104, a downstream end surface 104 extending vertically from the lower surface 104b.
The light source is accommodated in a space 104s adjacent to the downstream side of the downstream end face 104c. The light source is composed of three white light emitting diodes 108 arranged substantially horizontally, and these light emitting diodes 108 emit white light toward the downstream end surface 104c of the downstream viewer plate 104 located on the upstream side. . The white light emitted from the light emitting diode 108 enters the cross section of the acrylic plate-shaped main body from the downstream end surface 104c, irradiates the reflective member layer 106 and reflects it therefrom, so that the operator from an upper viewpoint can view the light. Indicates that the entire surface of the downstream viewer plate 104 is in a bright state.

In the vicinity of the upstream end of the generally horizontal lower surface 104b of the upstream viewer plate 104, light that enters the cross section of the upstream viewer plate 104 from the downstream end surface 104c and travels upstream in the horizontal direction. There is provided an inclined surface 104d for reflecting light upward. In other words, most of the light reaching from the downstream end surface 104c to the upstream end of the upstream viewer plate 104 via the cross section of the upstream viewer plate 104 is directed upward, and the light near the cutting line is effectively used. Irradiation does not occur laterally from the upstream end. The inclined surface 104d is installed so as to be inclined by 45 ° with respect to the horizontal, and the upper end of the inclined surface 104d is also coincident with the cutting line L0. Reflective member layer 10
Reference numeral 6 denotes a coating film made of white fine particles such as titanium oxide, zinc oxide, or alumina, similarly to the reflection member layer 6 of the upstream viewer plate 104. Therefore, a part of the light beam emitted from the light source 108 and entering the cross section of the upstream viewer plate 104 is scattered in various directions by the irregular reflection surface, and the lower surface of the upstream viewer plate 104 (reflection member layer 1).
06 (equivalent to the upper surface of No. 06) is a bright surface with substantially uniform brightness.

Therefore, most of the light rays emitted from the light source 108 enter the cross section of the downstream viewer plate 104 from the downstream end surface 104c of the downstream viewer plate 104 (in which the reflection member layer is not provided). After that, a substantially horizontal lower surface 10
While irradiating the reflecting member layer 106 of FIG. 4b, the light travels substantially horizontally in the colorless and transparent acrylic material of the downstream viewer plate 104, and is reflected by the inclined surface 104d near the upstream end of the downstream viewer plate 104 to be reflected upward. , A photographic film (F or P) portion located above the downstream viewer plate 104 is irradiated from below and penetrates the photographic film (F or P).
Finally reach the eyes E of the operator.

That is, as shown in FIG. 8, when viewed from the operator, the photographic film located on the upstream side of the cutting line LO from the light source 8 installed at the upstream end of the upstream viewer plate 4. It is fully illuminated with the emitted light,
On the other hand, at the same time, the photographic film located on the downstream side of the cutting line LO is sufficiently irradiated with light emitted from the light source 108 installed on the downstream side of the downstream viewer plate 104. Further, the cutting line L0 located at the downstream end of the upstream viewer plate 4 and at the same time as the upstream end of the downstream viewer plate 104 is connected to the eyes E of the operator located on the upstream side of the normal cutting line L0. Is located between the downstream viewer plate 104 that is in a brilliant state by the light source 108, and the blank portion of the photographic film disposed on the cutting line L <b> 0 is a brilliant surface of the downstream viewer plate 104, particularly the inclined surface 104 d. In front of is clearly visible,
The operation of positioning the vicinity of the center of the plain portion on the cutting line can be very easily performed. As best shown in FIGS. 5 and 7, the upper surface 104a of the downstream viewer plate 104 also has
Reference lines L3, L4, and L5 are graduated as a reference when the cutting line is set within a boundary region between image frames on a normal 35 mm photographic film.

(Negative Sheet Position Abnormality Warning Mechanism) In the photographic film processing apparatus of the present invention, 50 sheets of the negative sheet 40 are formed by the motor M2 and the sheet conveying rollers 44, 44.
If the negative piece insertion pocket 40p is not located at an appropriate position downstream of the negative piece on the upstream viewer plate 104, regardless of the transport operation of feeding by mm, the position abnormality warning means 110 that warns the operator of this is provided. . The negative sheet position abnormality warning unit 110 includes a sheet mark sensor 52 (an example of a unit that detects the coincidence of the pocket portion with the proper position) for detecting the sheet mark 40a, which has already been described in the section related to the configuration of the envelope unit.
Upstream viewer plate 4 by light emitting diode 8 (108)
Or means for changing the irradiation state of the photographic film on the downstream viewer plate 104.

Here, the means for changing the irradiation state is voltage operating means 120 for changing the light emission intensity of each of the light emitting diodes 8 and 108 with time. More specifically, the voltage operating means 120 is connected to each of the light emitting diodes 8 and 10.
The light emitting diodes 8 and 108 are turned on and off by continuing the operation of turning the power supply state on and off at intervals of several seconds. However, each light emitting diode 8,
The state in which the light emission state of 108 changes between a high luminance state of a normal light amount and a low luminance state of a small light amount by 20% at intervals of several seconds may be continued. Further, the light emitting diodes 8 of the upstream viewer plate 4 and the light emitting diodes 108 of the downstream viewer plate 104 may be turned on and off at the same time, or may be turned on and off alternately. When the sheet mark sensor 52 cannot detect the sheet mark 40a irrespective of the operation of transporting the negative sheet 40 by the sheet transport rollers 44, 44, the control means determines that the "negative sheet position is abnormal".
It is configured to drive the voltage operation means 120 by judging. This negative sheet position abnormality warning means 110
The problem is that the photographic film on the upstream viewer plate 104 is fed by the negative insertion motor M1 not into the correct negative piece insertion pocket (the appropriate position) but into the heat-sealing portion between the negative piece insertion pockets, Prevents the negative cutter from being cut by the rotary cutter 48 at the pocket portion containing the negative piece.

As shown in the block diagram of FIG. 10, on the other hand, an output system for outputting operation signals to the negative insertion motor M1, the sheet conveying motor M2, and the voltage operation means 120 is connected to the control means. On the other hand, the first sensor and the second sensor 15 of the negative cut lever 15
a, an input system for receiving signals from the sheet conveying motor M2 and the sheet mark sensor 52 is provided.
The voltage operating means 120 is connected to the light emitting diodes 8 and 108 of the upstream and downstream viewer plates 4 and 104, respectively.

10). The blinking continues for about 15 seconds and automatically recovers to the normal steady lighting state (# 111). Usually after this,
It is sufficient to return to step # 100.

<9> On the other hand, at this time, if the sheet mark sensor 52 detects the sheet mark 40a (# 1)
09, the negative sheet position abnormality warning means 110 does not work, and the "negative piece P in the negative insertion pocket 40p on the downstream viewer plate 104 is the last negative piece of the order". When the operator recognizes that the negative sheet 40 is in the negative insertion pocket 40p by operating the sheet cut lever 50 as it is (determination of "Yes" in # 112).
Cutting is performed at the boundary between the two (# 113).

<10> In addition, the "downstream viewer plate 104"
When the operator recognizes that the negative piece P contained in the upper negative insertion pocket 40p is not the last negative piece of the order (determination of "No" in # 112), the step of (# 101) Then, the operation of inserting the photographic film F into the negative insertion pocket 40p is restarted.

[Another Embodiment] <1> Normal irradiation light by irradiation means is only white light,
When the negative sheet position abnormality warning unit 110 is driven, that is, in an abnormal state, the non-white light and the white light may be alternately turned on at intervals of several seconds.

<2> Means for changing the direction of light emitted from the light source is provided as the negative sheet position abnormality warning means without providing means for changing the light amount of the light source itself constituting the irradiating means. Thus, the irradiation state of the photographic film by the irradiation means may be changed.
As a specific structure of the “means for changing the direction of light emitted from the light source”, for example, a light source component (light emitting diode) is mounted on a base that is swingably supported about a horizontal axis. ) Is provided, and when a warning is issued, this table is moved between a position where the center of the light emitted from the light source irradiates the photographic film by the DC motor or the like and a position where the center of the light emitted from the light source is off the photographic film. The rocking operation can be performed with. Also,
Instead of swinging the base that supports the light source components,
As shown in FIG. 12, taking the downstream viewer plate 104 as an example, the light source 108 is disposed at a position separated downward from the downstream viewer plate 104, and the light emitted from the light source 108 is directed toward the end face 104c. A reflecting means 155 such as a reflecting mirror or a prism is provided in the space 104s adjacent to the downstream side of the downstream end face 104c so that the reflecting means 155 moves forward. The driving means 160 swings the reflecting means 155 within a predetermined angle range. (Such as a servomotor) may be provided.

<3> The negative sheet position abnormality warning means may repeatedly change the wavelength of light for irradiating the photographic film. A change in the wavelength of the light illuminating the photographic film appears to the operator as a change in the tint of the light illuminating the photographic film and, consequently, a change in the hue of the image of the photographic film being illuminated. Know the operator. Incidentally, as a method of changing the wavelength of the light illuminating the photographic film, the irradiating means may be constituted by a plurality of light sources having different emission colors, and a method of alternately blinking the plurality of light sources having different emission colors may be employed. good.

<4> As a light source, a light emitting diode (L
In addition to ED), a lamp with a reflection plate or a fluorescent tube can be used. However, since the directivity of the fluorescent tube is low, in order to effectively illuminate the cutting line, the directivity may be provided by auxiliary means such as a condenser lens.
