Then, while the sheet P is being conveyed between the pair of conveying rollers 5 and 6, the image information of the sheet P is recorded by the recording unit 14. The recording unit 14 is a reduction projection optical system, a photoelectric conversion reading system, or the like, and records image information of the conveyed sheet P on an electric recording medium such as a magneto-optical disk.

[0005] In the image recording apparatus 10, a sheet detection sensor 11 is disposed between the pair of transport rollers 4 and 5 upstream of the recording unit 14 in the sheet transport path in the sheet transport direction. The detection signal of the leading edge of the conveyed sheet by the sensor 11 is input to the control circuit 12 in the image recording apparatus 10. The control circuit 12 determines the recording start timing of the recording section 14 of the image recording apparatus, the illumination lamps 15 and 16 based on the input signal.
, The lighting timing of the blip mark LED 20 and the film cassette drive system 19 are operated to control the shooting start timing of the film cassette 30 and the like.

Here, the blip mark is also called an image mark or a document mark, and is a rectangular mark provided to facilitate automatic counting and retrieval of the film developed after photographing. The width of this mark is determined by the blip mark LED provided in the image recording device.

In the process of the sheet P passing through the transparent glass plates 17 and 18 between the pair of conveying rollers 7 and 8, the image of the sheet P is illuminated by the illumination lamps 15 and 16 and the "C" shaped mirrors 21 and 22 and the slit 27 and mirror 23,
It is guided to the photographing opening 31 of the film cassette 30 of FIG. 11 via 24 and 25 (see FIG. 10). The image of the sheet P guided to the photographing opening 31 is formed by an imaging lens 41.
, And is reduced and photographed on the film F wound around the capstan roller 34 by a slit exposure method. The recorded sheet P that has passed through the transparent glass plates 17 and 18 is
The paper is sequentially discharged to the paper discharge tray 1 'after passing through the conveying roller pairs 8, 9.

The camera magnification detecting sensor 26 shown in FIG. 9 detects the frame 44 pressed into the film cassette 30 and inputs the reduction ratio of the imaging lens 41 of the film cassette 30 to the control circuit 12 shown in FIG. Based on this information, the control circuit 12
Controls the capstan roller 34 to a rotational speed corresponding to the contraction ratio of the imaging lens 41. In addition, it controls the positioning of a later-described blip mark LED 20.

Each roller 2, 3, on the image apparatus 10 side in FIG.
The drive motors 4, 5, 6, 7, 8, and 9 are driven by a drive motor 13 in the image recording apparatus 10 by drive transmission means such as a belt and a gear (not shown). The capstan roller 34, the supply side engagement member 32, and the winding side engagement member 3 of FIG.
The rotation speed of the encoder 3 is controlled by the encoder 5 provided integrally with the drive shaft 51 of the image recording apparatus corresponding to each of FIG.

The rotation of the encoder 57 and the drive gear 64 can be detected indirectly by detecting the rotation of the encoder 57 and the drive gear 64 by the rotation detecting means of the photo interrupters 5 and 59 and 60.
Encoder 5 corresponding to rotation of capstan roller 34
The rotation of 7 is constant. The rotation of the drive gear 64 corresponding to the rotation of the supply-side engagement member 32 and the take-up side engagement member 33 changes depending on the film winding diameter of the supply reel 42 and the take-up reel 43 (FIG. 11) mounted and supported respectively. I do. Thus, by comparing and measuring the time interval of the pulse generated from the rotation detecting means of each gear and its change, it is possible to control the transport of the film in the film cassette 30 or to detect the remaining amount.

FIG. 9 is a main cross-sectional view in which the film cassette 30 is mounted on the image recording apparatus 10. A connecting plate 39 is provided integrally with the capstan roller 34, and a driving connecting plate 50 shown in FIG. The drive connecting plate 50 is integrally fixed to the drive shaft 51.

Opposed to the (or concave), a fitting concave 62 (or convex) of the connection driving plate 61 is provided. By connecting these two, the rotational torque of the motor 67 in FIG. 17 is reduced by the gear 66 and the drive gear 64 provided integrally with the drive shaft 63.
The take-up reel shaft 36 shown in FIG.
Is transmitted to the connection plate 37 provided integrally with the first plate. The take-up side engaging member 33 inserted into the take-up reel shaft 36
Is rotated. The connection of the supply side engagement member 32 is the same as that of the winding side engagement member 33. Note that a holding force is applied to the motor 68 on the supply side so that the film is fed by the capstan roller 34. As a result, the film adheres to the capstan roller 34 and the capstan roller 34
Film feed utilizing the frictional resistance of the film. Although a motor is used in this example, a friction mechanism such as a torque limiter may be used.

FIG. 12 shows the above-described blip mark.
As shown in (2), the light source of the blip mark LED 20 is exposed to the film F via the mirrors 23, 24, 25 and the imaging lens 41 in the film cassette 30.
The blip mark width L can be set to three types of large (batch mark), medium (file mark), and small (page mark) by changing the light emission time of the light source 45 arranged on the blip mark LED 20 provided in the image recording apparatus 10.

Increase or decrease the lighting time of 0.

The optical path width H of a plurality of light sources 45 provided on the blip mark LED 20 is set to a desired height according to the contraction ratio of the imaging lens 41. When the light source 45 of the blip mark LED 20 is turned on, the optical path width H of the light source 45 is reduced to the blip height H1, and an image is formed on the film F.

However, when film cassettes having different shrink ratios are mounted as shown in FIG. 13 (for example, a film cassette dedicated to front-side photographing), the blip mark is not required for the film F due to the difference in shrink ratio of the imaging lens 41. No image is formed at the position. As a means for solving this problem, as shown in FIG.
Is moved in the direction of the arrow from the position. It should be noted that the difference in the shrinkage ratio is different from the camera magnification detection sensor 26 shown in FIG.
Is detected based on where the frame 44 has entered, and this information is input to the control circuit 12.

FIG. 15 is a schematic perspective view showing a moving means of the blip mark LED 20. The above-mentioned reduction ratio information is transmitted from the control circuit 12 to the stepping motor 71 fixed to the housing 70 by fixing means such as screws. The blip mark LED 20 is fixed to the moving plate 80 with a screw 79. Both ends of the slide shaft 76 are integrally supported by the ends of the housing 70, and a moving plate 80 is connected to the slide shaft 76. The timing belt 72 includes a movable plate 80 and a screw 7.
8 is clamped by the fastening plate 77 fixed. Moving plate 8
The blip mark LED 20 fixed to 0 can be moved to a predetermined position via the pulleys 73, 74, 75 and the timing belt 72 when a rotation command is given from the control circuit 12 to the stepping motor 71. The home position of the blip mark LED 20 is set by detecting a detection unit 81 of the moving plate 80 by a photo interrupter 82 provided integrally with the housing 70. Thus, after detecting the home position, the blip mark LED 20 is moved to a desired position according to a rotation command from the control circuit 12.

[0016]

However, in the above-described conventional example, a blip mark LED as shown in FIG.
It is essential that the 20 means of transport are built into the body. Since the light source of the blip mark LED 20 is projected on the mirrors 23, 24, and 25 as shown in FIG. 12, the size of the mirror becomes large, and the frame becomes large accordingly. Accordingly, the optical adjustment of the blip mark LED needs to be performed separately from the imaging optical path, so that the number of adjustment steps increases. Further, in order to achieve the moving means with high accuracy, the number of parts is increased, which leads to an increase in cost and size of the apparatus.

The image of the sheet P guided to the photographing opening 31 passes through the imaging lens 41 and the slit 104 and is reduced and photographed on the film F wound around the capstan roller 34 by the slit exposure method. You.

The shutter 105 is opened only by the shutter solenoid 106 of the image recording apparatus as shown in FIG. The shutter 105 rotatably fixed to the slit 104 by a shaft 109 is integrally formed with a rotation shaft 110, and the rotation shaft 110 is inserted into an elongated hole 114 of the shutter arm 107.

When the shutter solenoid 106 is turned on, the shutter arm 107 is lifted in the direction of the arrow, so that the shutter 105 having the rotating shaft 110 inserted into the elongated hole 114 rotates clockwise about the shaft 109. I do. Thereby, the photographing opening window 112 of the slit 104 is formed.
Then, the blip mark opening window 111 appears, and the camera is ready to be photographed.

The blip mark LED 100 directly attached to the substrate 115 of FIG.
2 is fixed with fixing screws 103. Near the slit 104 of the film cassette 30 and the center of the imaging lens 41,
A reflection mirror 101 for changing the optical path of the blip mark LED 100 is provided. The arrangement angle of the reflection mirror 101 is about 45 °, and by arranging the blip mark LED 100 directly below the reflection mirror 101 as shown in FIG. Mirror 1
01 forms an image on the film F wound around the capstan roller 34. In the above case, a mirror is used for the reflector, but the present invention is not limited to this, and any object that reflects light can be applied to the reflector.
