DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographic film cutting device, and more particularly, to a mounting table on which a photographic film can be mounted, means for cutting the photographic film on the mounting table, Means for irradiating the photographic film on the table from below. A general roll-shaped photographic film subjected to exposure and development processing (hereinafter referred to as a roll film) has a plurality of image frames separated by a blank portion having a width of several mm. The roll film is used to cut the roll film into a strip-shaped piece film which is easy to handle, for example, every six frames. Generally, the resulting piece film is inserted into a translucent negative sheet (sometimes called a sleeve) by a film inserter located adjacent to the cutter as part of a cutting device and returned to the customer.

[0002]

2. Description of the Related Art In a photographic film cutting apparatus having the above structure, a cutting operation can be performed with the photographic film being positioned on the mounting table, and the photographic film on the mounting table is irradiated from below. The transmitted light passes through the photographic film and passes upward.
These arrangements are mainly intended to allow a cutting operator who places his eyes above the photographic film to cut the blade with the cutter blade precisely aligned with the plain portion.

[0003]

However, in the above-mentioned conventional example, since a bar-type lamp or a fluorescent lamp is used as means for irradiating the photographic film on the mounting table from below, there are some problems. Was seen. That is, in the case of a barbecue lamp, the installation space is relatively small, but at the same time, the color temperature of the emitted light is low (that is, reddish). System base film), it was very difficult to distinguish the image from the base portion.
In addition, in the case of fluorescent lamps, relatively white light can be obtained, but in addition to the problem of difficulty in viewing due to flickering and the problem of heat generation, it also helps to emit light while reducing the installation space of the fluorescent lamp itself. There was a problem that a relatively large inverter was required as equipment.

Accordingly, it is an object of the present invention, in view of the aforementioned disadvantages of the prior art photographic film cutting devices exemplified above, regardless of the color of the base film of the photographic film or the color of the image carried. Provided is a photographic film cutting device that can easily perform an operation of discriminating an image from a base portion such as a blank portion, has less problems of flicker and heat generation, and requires a relatively small installation space of an irradiation unit including auxiliary equipment. Is to do.

[0005]

According to a first aspect of the present invention, there is provided an apparatus for cutting a photographic film, wherein the irradiating means comprises a light emitting diode for irradiating the lower surface of the photographic film with white light. Is a characteristic configuration.

That is, in the photographic film cutting apparatus according to the first aspect of the present invention, since the light emitting diode is used as the irradiating means, the problem of heat generation by the irradiating means is suppressed. Advantages such as a small installation space for the means are obtained. Further, for the operator of the cutting work, the visibility due to the flicker is eliminated, and since the light emitting diode that irradiates the lower surface of the photographic film with white light is used, the base film of the photographic film has an orange color. In the case of the color negative, the advantage that the operation of discriminating the image from the base portion can be easily performed regardless of the color of the carried image was obtained. However, here, the white light is about 400 light so as to be felt white when it enters human eyes.
nm, about 600 nm, and about 700 nm.

A colorless and translucent member is disposed below the photographic film on the mounting table (of course, the mounting table itself may be a translucent member), and the light emitting diode itself emits white light. A white light emitted from the light emitting diode may be configured to pass through the cross section of the light transmitting member and reach the lower surface of the photographic film. With this configuration, the white light emitted from the light-emitting diode is attenuated in the cross section of the light-transmitting member by dust and the like in the air (because the light-emitting diode has higher directivity than a fluorescent tube or the like). Can be efficiently passed to the lower surface of the photographic film, so that the cutting operation including the position determination of the unpeeled portion of the operator is further facilitated.

Alternatively, a translucent member is arranged below the photographic film on the mounting table (of course, the mounting table itself may be a translucent member), and the light emitting diode itself emits non-white light. Instead of using a light emitting diode, a means for correcting non-white light emitted from the light emitting diode to white light is provided, and the non-white light emitted from the light emitting diode passes through the cross section of the light transmitting member and is finally It is also possible to configure so that the white light is eventually emitted and reaches the lower surface of the photographic film. Even with this configuration, the non-white light emitted from the light-emitting diode enters the cross-section of the translucent member, and thereafter, the inside of this cross-section is minimized by attenuation due to dust or the like in the air. Since the light passes through the screen and finally becomes white light and efficiently reaches the lower surface of the photographic film, the cutting operation including the position determination of the unpeeled portion of the operator is further facilitated.

For example, as means for correcting the non-white light emitted from the light emitting diode to white light, a translucent member colored in a color complementary to the non-white light can be used. As an example, a combination of a blue light emitting diode and a translucent member colored yellow may be used.

Alternatively, when a non-light-transmitting reflection layer is provided on the lower surface of the light-transmitting member, the means for correcting the non-white light emitted from the light emitting diode to white light may include the reflection layer. And a hue that is in a complementary color relationship with the light source. As an example, a combination of a blue light emitting diode and a yellow reflective layer may be used.

As one specific example, a supply direction of the photographic film to the table is set, and the cutting means is arranged at a downstream end of the table in the supply direction. Constitutes the light-transmitting member, and the light-emitting diode irradiates light toward an upstream end surface of the light-transmitting member, whereby the white light is cut by the cutting unit of the photographic film. May be applied. With this configuration, it is possible to sufficiently irradiate the through hole to be cut particularly with the light transmitted by the mounting table as the light guide plate from the upstream side, and at the same time, dispose it at one end of the translucent mounting table. By the light emitted from the light emitting diode, substantially the entire surface of the mounting table can be illuminated (for example, if a reflective layer is applied to the lower surface of the mounting table).

As another specific example, a supply direction of the photographic film to the mounting table is set, and the cutting means is disposed at a downstream end of the mounting table in the supply direction. Further downstream of the mounting table,
A film inserter section for inserting the photographic film cut into pieces by the cutting means into a bag-shaped film sheet is provided, and the film inserter section is located below the film sheet containing the photographic film. A second light-transmitting member is provided, and the light-emitting diode emits light toward a downstream end surface of the second light-transmitting member, whereby the white light is photographed by the cutting means. It may be configured to irradiate the cut portion of the film. According to this structure, it is possible to sufficiently irradiate the through-hole to be cut particularly with the light transmitted by the second light guide plate from the downstream side, and at the same time, disposed at one end of the second light guide plate. Almost the entire surface of the second light guide plate can be illuminated by the light emitted from the light emitting diode (for example, if a reflective layer is applied to the lower surface of the second light guide plate).

[0013] Other features and advantages of the present invention include:
The description will become apparent from the description of the embodiment using the drawings.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. The photographic film cutting device, 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. Used to be placed. This photographic film processing apparatus includes a cutter unit 1 for cutting a long photographic film F into short negative pieces P (in principle, a film having images of 6 frames or 4 frames), and a negative piece P cut by the cutter unit 1.
And an enveloper section 2 for storing in a negative sheet 40 made of resin and provided with many pockets.

(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) or the like. An upstream viewer plate 4 made of colorless and transparent acrylic (an example of a mounting table and a translucent member) installed substantially horizontally, a cutter 10 for cutting a photographic film F on the upstream viewer plate 4, and an upstream A light source 8 for irradiating the photographic film (F or P) on the side viewer plate 4 from below. 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); Lower blade 1 across cutting line L0
2 and an upper blade 14 adjacent to the downstream side. The upper blade 14 is pivoted with respect to the fixed lower blade 12 by a manual operation of pushing down from a home position via a pivotable negative cut lever 15 shown in FIGS. The boundary between the lower blade 12 and the upper blade 14 is configured to coincide with the cutting line L0.

As is well shown in FIG. 8, near the upstream end of the substantially horizontal lower surface 4b 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 8 (LEDs) arranged substantially horizontally, and these light emitting diodes are all white diodes that emit white light. The white light emitted from these light emitting diodes is applied to the upstream end face 4c of the upstream viewer plate 4 located on the downstream side. Here, the white diode is different from a normal single-color LED having a single wavelength peak, and is approximately 400 n.
Refers to an LED that is configured to emit light that is perceived as white by the naked human eye to moderately contain light of a wavelength from m to about 700 nm. It should be noted that the white diode 8 used here is more specifically a B (R
It is composed of an LED chip B) of GB and a phosphor for color correction arranged at the tip of the blue LED chip. The blue light emitted from the blue LED chip is accompanied by a wavelength region inherent to the phosphor for color correction when passing through the phosphor for color correction, and at least apparently, as white light. Finally, it is emitted to the outside and the upstream viewer plate 4
On the upstream side end face 4c. The emission spectrum of the white light emitted from the white diode 8 has a wavelength component having a peak at about 470 nm of the light emitted from the blue LED chip and a wavelength component having a peak at about 560 nm generated by the phosphor for color correction. Having.

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 4 which extends vertically from the substantially horizontal upper surface 4a of the upstream viewer plate 4.
d, a third end face 4f extending slightly inclining downstream from the lower surface 4b, and a second end face 4e connecting the first end face 4d and the third end face 4f so as to be further inclined than the third end face 4f. Consists of The lower blade 12 extends from the first end surface 4d to the second end surface 4e, and the end surface 12a forming the edge of the lower blade 12 and the first end surface 4d of the upstream viewer plate 4 are
These coincide with each other in the photographic film supply direction, and they also coincide with the cutting 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 surface 4e, and the third end surface 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. Here, the hue of the fine particles is preferably white. 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, a part of the white 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 reflecting member layer 6). Is substantially uniform and has high 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, the light beam incident on the cross section of the upstream viewer plate 4 forms a good white brilliant surface based on the white light emitted from the white diode 8 and the white reflecting member layer 6. As a result, the operator who puts the eye E above the upstream viewer plate 4 can use the photographic film (F or F) irradiated with a sufficient amount of light while using the white glittering surface formed by the reflecting member layer 6 as a good background. P) 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 is provided.
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 (not shown).
The negative cut lever 15 is provided with a home position with respect to its swinging posture, and when the operator lifts the negative cut lever 15 above the home position,
A first sensor (not shown) detects the change in the attitude of the negative cut lever 15, and based on this detection signal, the transport roller 20 is lowered to the operating position, and at the same time, the lower transport roller 22 starts rotating. The controller is configured to send the photographic film P on the upstream viewer plate 4 to the downstream side, that is, into the pocket of the negative sheet set in the enveloper section 2. 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 transport roller 22 is stopped, and the upper transport roller 20 moves up to the standby position. In addition, photographic film P
Of the photographic film F at the same time as the downstream end of the negative sheet reaches the bottom of the pocket of the negative sheet.
The outer periphery of 2 is made of smooth stainless steel having a small coefficient of friction. 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.

As an auxiliary tool for completely inserting the photographic film P, whose rear end remains upstream of the cutting line L0, into the pocket of the negative sheet, a manual insertion device,
An auxiliary inserter 24 is provided. As shown in FIG. 4, the auxiliary inserter 24 includes two link members 28.
a and 28b, a standby posture hidden below the level of the upper surface 4a of the upstream viewer plate 4 (the state shown in FIG. 4A) and a downstream position in the photographic film supply direction from the standby posture. The push piece 26 is capable of reciprocating with respect to a working position (a broken line in FIG. 4-B).
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 action posture, the downstream end of the pushing piece 26 is provided with a slit 4G formed in 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. The handle member 30 is swingably supported around the axis X, and when the handle member 30 is tilted in the direction of arrow A, the disk member 32 fixed to the base end of the handle member 30 near the axis X is formed. The operating pin 32a swings the link member 28b to the right in the drawing 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. Presser roller 3
Numeral 4 is rotatably supported around a fixed axis, and an outer peripheral portion of a pressing roller 34 formed of an elastic material such as rubber presses the photographic films F and P against the upper surface 4a of the upstream viewer plate 4.

(Structure of Enveloper Unit) As shown in FIGS. 1 and 2, the enveloper unit 2 converts the negative sheets 40 accumulated in a roll form in the 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 for pulling out the negative sheet 40 to a position on the downstream side, and a receiving member 46 for expanding the insertion opening of the pulled-out negative sheet 40 to assist the insertion of the photographic film P.
(See FIGS. 3 and 4), a rotary cutter 48 (only the cover part is shown) for cutting several stages of the negative sheet 40 into which a series of photographic films P have been inserted, and the rotary cutter 48 is manually driven. Sheet cut lever 50 for
The negative sheet 40 includes a sheet mark sensor 52 (see FIG. 3) for optically detecting sheet marks printed near the bottom of each of the negative piece insertion pockets provided on the negative sheet 40. A second sensor (not shown) that detects movement of the negative cut lever 15 to the bottom dead center is provided below the home position described in the configuration of the cutter unit. That is, when the operator pushes 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 is lowered. The second sensor detects the upward movement from the point, and based on this detection signal, the controller (not shown) drives a driving motor for the sheet conveying rollers 44, 44 to move the negative sheet 40 by one pitch. The negative sheet 40 is pulled out by the distance (corresponding to the distance between the centers of adjacent pockets, which is about 50 mm in this embodiment), and the negative sheet 40 is positioned to receive the next photographic film F.

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 each light emitting diode 108 is the same as the light emitting diode 8 described above. 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
c, enters the cross section of the acrylic plate-shaped main body, irradiates the reflecting member layer 106 and reflects the light therefrom, so that the entire surface of the downstream viewer plate 104 is in a white brilliant state from an operator with an upward viewpoint. Present. Also, near the upstream end of the generally horizontal lower surface 104b of the upstream viewer plate 104, the light that enters the cross section of the upstream viewer plate 104 from the downstream end surface 4c and travels toward the upstream in the horizontal direction is directed upward. An inclined surface 104d for reflection is provided. In other words, most of the light that reaches the upstream end of the upstream viewer plate 104 from the downstream end surface 4c through 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 45 with respect to the horizontal
° so as to be inclined by 104 °.
Is also coincident with the cutting line L0.

Also here, the coating film forming the reflecting member layer 106 is made of the same material as the above-mentioned reflecting member layer 6 and has almost the same function. At the same time, light rays that have once entered the cross section of the downstream viewer plate 104 are prevented from passing through the lower surface of the downstream viewer plate 104 and escaping to the outside. 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,
The lower surface of the upstream viewer plate 4 (equivalent to the upper surface of the reflection member layer 6) is a substantially uniform and bright white brilliant surface. 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 face 104c of the downstream viewer plate 104 (where no reflecting member layer is provided), and then substantially. While irradiating the reflective member layer 106 on the horizontal lower surface 104b, the light advances 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. The photographic film (F or P) located above the downstream viewer plate 104 is irradiated from below and transmitted therethrough.
Finally, it passes through the vicinity of 0, that is, the gap between the upper blade 14 and the lower blade 12, and finally reaches the eye E of the operator. That is, as illustrated in FIG. 8, when viewed from the operator, the photographic film located on the upstream side with respect to the cutting line LO is emitted from the light source 8 installed at the upstream end of the upstream viewer plate 4. Fully illuminated with white light, while at the same time,
The photographic film located on the downstream side of the cutting line LO is sufficiently irradiated with white light emitted from the light source 108 installed on the downstream side of the downstream viewer plate 104. Also,
The cutting line L0 located at the downstream end of the upstream viewer plate 4 and at the same time at the upstream end of the downstream viewer plate 104 is:
Since it is located between the operator's eyes E located on the upstream side of the normal cutting line L0 and the downstream viewer plate 104 in a bright state by the light source 108, it is arranged on the cutting line L0. The blank portion of the photographic film appears clearly in front of the white glittering surface of the downstream viewer plate 104, particularly the inclined surface 104d, and the operation of positioning the vicinity of the center of the blank portion on the cutting line is very difficult. Easy.

As best shown in FIGS. 5 and 7, the upper surface 104a of the downstream viewer plate 104 is also used as a reference when placing the cutting line within the boundary area between image frames on a normal 35 mm photographic film. Reference lines L3, L4, and L5 are graduated.

An R-color LED chip having a wavelength peak at about 690 nm,
A G color LED chip having a wavelength peak at about 600 nm,
For example, a white diode of a type including a combination of B-color LED chips having a wavelength peak at about 500 nm in one LED module may be used.

<3> Alternatively, as the correction means, the reflection layers 6 and 106 provided on the lower surfaces of the viewer plates 4 and 104 on the upstream and downstream sides can be used. For example, when a light emitting diode that emits blue light is used, the reflection layers 6 and 10 provided on the viewer plates 4 and 104 on the upstream and downstream sides are used.
6 may be colored in yellow or the like that is complementary to the blue light.

<4> The viewer plates 4 and 104 are colorless and transparent, and the reflection layers 6 and 106 are white. On the other hand, a plurality of types of non-white light emitting diodes having different emission colors are used. The light of these different colors may be mixed with each other inside the viewer plate 4 and the light guide plate 104 so that the light reaches the eyes E of the operator as white light. In this case, in order to promote mixing of lights of different colors, a reflective layer of white or the like is also provided on the end face on the side surface of the viewer plates 4 and 104 so that the viewer plates 4 and 104 constitute a kind of mirror tunnel. You may do it.

<5> Further, as shown in FIG.
The light source 108 is disposed at a position separated downward from the downstream viewer 104, and the light emitted from the light source 108 is reflected to the space 104s adjacent to the downstream side of the downstream end surface 104c so that the light beam proceeds toward the end surface 104c. A reflecting means 155 such as a mirror or a prism may be provided. This arrangement of the light source can be adopted for the light source 8.
