The light source unit 16 is a light source for projecting an image on the film 52 onto the imaging unit 19. The image scaling unit 17 controls the movement of the lens group that changes the image magnification when the image on the film 52 is projected on the imaging unit 19. When the vertical / horizontal conversion unit 18 determines that the frame is photographed at a vertical position based on the magnetic information, the vertical / horizontal conversion unit 18 controls the rotation of the prism that rotates the image by rotating the center of the optical axis in order to form an image on the television. The image pickup unit 19 uses an area sensor as an image pickup device that converts the image information on the film surface photographed by the lens into an electric signal.

Next, a detailed description will be given for each block.
FIG. 4 is a diagram showing a drive system of the film feeding unit. The film feeding unit 14 is a feeding motor 20 as a drive source, a driver unit 21 rotatably instructed by the cartridge loading unit 13 to access the cartridge 53, and a driver unit associated with the loading operation of the cartridge loading unit 13. 21 and the connection mechanism 22 for separating / connecting the drive system, and the film 5
2 is a speed absorbing mechanism 23 for preventing the loosening of the driver 2 and absorbing a speed difference between the driver portion 21 and the driving roller 24.
A drive roller 24 that feeds the film 52, a first planetary clutch 25 that disconnects the feed motor 20 and the drive roller 24, a speed detection mechanism 26 that detects the rotational speed of the drive roller 24, and a cartridge 53. It is composed of a spool 27 for winding the film 52 coming out of it and a second planetary clutch 28 for disconnecting the spool 27 depending on the rotation direction of the drive roller 24.

The feeding motor 20 is a step motor that facilitates feedback control. The driver unit 21 pushes out the film 52 in the cartridge 53 by the clockwise rotation of the feeding motor 20, and rewinds the film 52 into the cartridge 53 again by the counterclockwise rotation. Connection mechanism 22
Is a planetary gear 47 and a spurb 48 for urging the planetary gear 47 in the direction of pressing the planetary gear 47 and the planetary gear 47 to the meshing position with the driver part 21 (not shown).
Consists of. As a result, even if there is a meshing error with the driver portion 21 that has moved from the projecting position to the storage position, each tooth again ensures regular meshing immediately after the feeding motor 20 is driven. The speed absorbing mechanism 23 includes a third planetary clutch 29 and a one-way clutch that couples the sun gear and the gear to which the clutch is connected. The third planetary clutch 29 is connected by the output gear and the feed motor 20 rotating counterclockwise.

The one-way clutch 45 is disengaged only when the rotation speed on the output side increases. As a result, even when the feeding motor 20 rotates clockwise, the film 52 is driven by the driver portion 21 at a speed equal to or faster than the pushing speed of the driving roller 2
The transmission to the driver portion 21 is cut off only when pulled by 4. Otherwise, the driving force is transmitted to the driver portion 21 regardless of the rotation direction of the feeding motor 20. The drive roller 24 and the driven roller 38 (see FIG. 7) together with the film 5
When the feed motor 20 which is engaged with the first planetary clutch 25 is rotated clockwise, the film 52 is sent to the spool 27 without slipping, but the clutch 52 is disengaged from the counterclockwise direction. When rotating, the film 52
Follow without slipping.

The speed detecting mechanism 26 is composed of an encoder portion which rotates integrally with a gear portion which is interlocked with the driving roller 24, and a photo interrupter which monitors the encoder portion. As a result, the speed of the drive roller that rotates and follows the film 52 at all times is detected and fed back to the feeding motor 20 to control the moving speed of the film 52.

The second planetary clutch 28 is used for the feeding motor 2
A clockwise rotation of 0 connects with the spool 27, and a counterclockwise rotation causes the drive roller 2 to move due to the movement of the film 52.
A rotation of 4 breaks the bond. The spool 27 includes a drive unit that transmits the drive from the feeding motor 20 and a winding shaft for the film 52 that is frictionally coupled to the drive unit coaxially.
The spool 27 is always rotated faster than the drive roller 24, and the film 52 is wound around the spool 27. This prevents the film 52 from being stretched.

5 and 6 show the cartridge loading section 13
3 is a perspective view and a cross-sectional view of FIG. The cartridge chamber 3 in which the cartridge 53 is mounted on the upper surface of the cartridge loading unit 13
0 and the cartridge 53 are mounted so that a part thereof is exposed when the cartridge 53 is mounted, and a cartridge locking claw 32 for holding / releasing the mounted state of the cartridge 53. The department is looking. A film entrance / exit 301 is provided on the side surface. The cartridge locking claw 32 is biased so as to partially project to the side surface of the cartridge chamber 30, and is pushed and retracted by the cartridge 53 at the start of mounting, and again protrudes at the completion of mounting to hold the cartridge 53. A driver 211 projects from the bottom surface of the cartridge chamber 30. The driver 211 rotates integrally with the driver gear 212 and transmits the driving force of the feeding motor 20. Further, although it is always biased in the projecting direction, it is slidable in the axial direction and retracts to the outside of the cartridge chamber 30 when the engagement with the cartridge 53 at the time of mounting is poor, but the drive of the feeding motor 20 starts and the engagement position. When it comes to, it projects again.

FIG. 7 is a sectional view showing the construction of the driving roller 24 and the driven roller 38. The drive roller 24 has a drive unit 39.
And an edge follower 36. The drive unit 39 is located on the recording unit side (lower side) of the film 52, and is rotatably supported by the rotating shaft 46. The drive roller 24 includes a rubber portion 33 for preventing slippage with the film 52, a collar 34 for regulating the lower edge of the film 52, and a gear portion 35 for transmitting the driving force of the feeding motor 20. Edge follower 36
Is located on the upper side of the film 52, is rotatable coaxially with the drive unit 39, and is vertically slidable within a predetermined range. The edge follower portion 36 has a roller portion 49 having a diameter smaller than that of the rubber portion 33 so that the edge follower portion 36 positively slides on the film 52.
And a flange 60 for regulating the upper edge of the film 52 and a spring 37 for urging the edge follow portion 36 itself downward. The driven roller 38 sandwiches the film 52, is located at a position facing the drive roller 24, and is always biased in the direction sandwiching the film 52. With this configuration, the film 52
Can be directly driven and the end surface of the film 52 can be aligned to stabilize tracking.

8 and 9 are a conceptual view and a configuration diagram of a mechanism for bringing the film 52 into contact with the magnetic head 40 and retracting it. FIG. 9 is a diagram showing a state in which the cartridge loading unit 13 is housed in the viewing device 1. The magnetic head 40 and the film pressing roller 4 are provided between the drive roller 24 and the spool 27.
1 are positioned side by side, and the magnetic head 40 and the driving roller 24 approach each other to stabilize tracking and the film pressing roller 4.
The aim is to avoid the deterioration of the flatness due to the slack of the film 52 that can be caused by pressing / retracting 1. Film pressing roller 41
Is rotatably held by a roller lever 42 that is rotatably supported by the body of the ornamental device 1, and can be moved to a pressing position for pressing the film 52 against the magnetic head 40 and a retracted position by the rotation of the lever. This prevents scratches on the film when the magnetic head 40 does not read or write information. The roller lever 42 is driven by the advancing / retreating mechanism of the cartridge loading unit 13. A loading motor 43 that drives the cartridge loading unit 13 is connected by a gear to a rack 44 that is slidable in the loading unit movement direction on the upper surface of the cartridge loading unit 13. The rack 44 is normally biased to 89 per rack of the cartridge loading unit 13 so as to move integrally with the cartridge loading unit 13. The rack 44 moves in the storage direction beyond the storage position of the cartridge loading unit 13 against the biasing force, contacts the roller lever 42, and rotates as indicated by the arrow in FIG. The film pressing roller 41 is pressed / retracted depending on the amount of movement.

Next, the operation of each part will be described according to the procedure of using the viewing device. When the power is turned on, the color balance and white balance are automatically set, and the image inversion mode is automatically set to OFF. Then, when the operation button 12 is pressed, the loading motor 43 rotates in the protruding direction of the cartridge loading unit 13, and the cartridge loading unit 13 comes out to the entire panel through the rack 44 on the lower surface of the cartridge loading unit 13. When the cartridge loading unit 13 projects a predetermined amount, a switch (not shown) detects this and stops the loading motor 43. In this state, the exclusive push-out type cartridge 53 containing the developed film is mounted in the cartridge chamber 30.

First, the end surface of the cartridge 53 pushes the taper portion of the cartridge locking claw 32 protruding from the side surface of the cartridge chamber 30, and the cartridge locking claw 32 is retracted to the cartridge chamber 30 side. Soon, the end surface of the cartridge 53 comes into contact with the driver 211 and starts meshing. At this time, when the cartridge 53 and the driver 211 do not mesh well, the driver 211 is pushed and the cartridge chamber 30
Evacuate from. Immediately before the end surface of the cartridge 53 hits the cartridge chamber 30, the cartridge locking claw 32 projects again into the cartridge chamber 30 and the mounting is completed. The cartridge locking claw 32 restricts the push-out of the cartridge 53 by the driver 211 when the cartridge 53 and the driver 211 do not mesh with each other.

When the operation button 12 is pressed again, the loading motor 43 rotates in the storage direction, and the cartridge loading section 13 is stored in the viewing device 1. The completion of storage is detected by a switch (not shown), and the loading motor 43 is stopped. The urging force of the spring 70 that presses the cartridge loading unit 13 and the rack 44 against each other is stronger than the load during storage, and the rack 44 and the cartridge loading unit 13 move integrally. Further, when the driver gear 212 moving to the storage position and the teeth of the connection mechanism 22 do not mesh well with each other, the driver gear 212 retreats around the sun gear against the biasing force.

With the stop of the loading motor 43, the feeding motor 20 rotates clockwise. At this time, the driver gear 212 and the planetary gear 4 of the connection mechanism 22 that were out of mesh with each other
7 or the driver 211 and the cartridge 53 mesh with each other. The first planetary clutch 25 is connected to the drive roller 24, the second planetary clutch 28 is connected to the spool 27, and the third planetary clutch 29 is separated from the driver 211. As a result, the driver 211, the drive roller 24, and the spool 27 all rotate clockwise. The driver 211 pushes the film 52 in the cartridge 53, the pushed film 52 passes through the aperture 68, and the driving roller 2
4 and the driven roller 38.

The driven roller 38 is separated from the drive roller 24 by the thickness of the film 52 against the biasing force of the spring 70. The drive roller 24 sandwiches the film 52 together with the driven roller 38, and sends the film 52 at a higher speed by the frictional force generated by the urging force. Since the film 52 starts rotating the driver 211 from this time, the rotation of the output gear is faster than that of the input gear in the speed absorbing mechanism 23 between the driver 211 and the feeding motor 20, and the two gears are coupled. One-way clutch 45
The feed system does not stick out.

When the film 52 passes through the drive roller 24, the gap between the drive portion 39 and the collar 60 of the edge follow portion 36, which is slightly narrower than the width of the film 52, is widened against the biasing force of the spring 37. As a result, the film 52 absorbs its own width variation based on the collar 34 of the drive unit 39, and stabilizes the tracking. The film 52 sent to the drive roller 24 passes through the magnetic head 40 and the film pressing roller 41 following it. At this time, the magnetic head 40 and the film pressing roller 41 are separated from the passage of the film 52, so that the film 27 can be easily wound around the spool 27.

The film 52 sent out is stored in the spool chamber 90.
Enter and start winding around the spool 27. Spool 27
The peripheral speed of is faster than the feeding speed of the driving roller 24 and always tries to pull the film 52. However, when a load of a predetermined amount or more is applied, the driving force of the feeding motor 20 is cut off by the friction mechanism and the speed of the film 52 is reduced. Does not exceed the feed speed of the drive roller 24, and the film 52 is wound without slack.

When a counter (not shown) that counts the feed amount of the film 52 by the number of passing perforations counts a predetermined feed amount in which the film 52 winds around the spool 27, the loading motor 43 moves in the storage direction of the film 52. Rotate. Then, the rack 44 of the cartridge loading unit 13 moves against the urging force, and a part of the rack 44 contacts the roller lever 42 to rotate it. As a result, the film pressing roller 41 presses the film 52 against the magnetic head 40 outside the passage. And film 52
Read the magnetic information written for each piece from time to time. The read information is temporarily stored in the storage unit inside the viewing device 1.

The above-mentioned pre-wide system will be described below. After the counter counts all frames, the feeding motor 2
The drive of 0 is once stopped, and then the feeding motor 20 is reversed (counterclockwise). The first planetary clutch 25 rotates counterclockwise and the clutch is disengaged. Third planetary clutch 2
9 rotates clockwise, the clutch is engaged, and the one-way clutch 45 of the speed absorbing mechanism 23 always slides. As a result, the driver 211 rotates clockwise, and the film 52 starts to be wound into the cartridge 53. When the film 52 moves, the second planetary clutch 28 rotates clockwise, the clutch is disengaged, and the spool 27 becomes free. The film 52 is tensioned by the friction of the spool 27 so that slack does not occur.

The counter has an aperture 68 (see FIG. 12).
Then, the arrival of the final frame is detected, and the feeding motor 20 is stopped. Next, the loading motor 43 is driven in the projecting direction of the loading section 13 to move the rack 44 to 89 per rack of the cartridge loading section 13. As a result, the roller lever 42 that moves following the rack 44 rotates counterclockwise, and the film pressing roller 41 retreats out of the path of the film 52,
It prevents scratches on the film 52 during reproduction. This completes the initial loading of the film 52.

The frame feeding operation during reproduction is performed by winding the film 52 into the cartridge 53 by the counterclockwise rotation of the feeding motor 20. The feeding motor 20 is stopped by detecting the perforation of the film 52 by the counter. At this time, each clutch remains in the initial load completed state.

When the frame to be imaged is a panorama, the frame feeding operation is performed by temporarily aligning the screen and the aperture 68 and then feeding motor 2
Reverse 0 (counterclockwise). Each clutch is in the initial loading start state, and the film 52 is wound on the spool 27. At this time, the speed detection mechanism 26 causes the film 52
While watching the movement amount of the film 52, the film 52 is rewound by a predetermined amount so that the end of the frame is projected on the entire screen at a predetermined magnification. Imaging is started after the magnification of the imaging lens 72 is adjusted, and the feeding motor 20 is driven in the normal frame feeding direction (clockwise direction). Each clutch becomes the same as the initial load completed state. Also at this time, the moving speed of the film 52
Is detected by the speed detection mechanism 26 that detects the amount of rotation of the drive roller 24 that follows, and the feeding motor 20 is controlled so that the speed is always fed at a constant speed. When the amount of movement of the film 52 is such that the other end of the image pickup frame appears on the screen, the feeding motor 2
0 is again inverted (counterclockwise), and the panning operation is repeated within a predetermined time.

Cartridge loading operation button 1 during reproduction
When 2 is pressed, the feeding motor 20 is rotated in the clockwise direction (the clutch is in the initial loading completion state), the counter detects the end of the film, and the feeding motor is continuously rotated for a while and the film 52 is completely cartridgeed. Roll in 53. After winding the film 52, the feeding motor 20 is stopped. Then, the loading motor 43 is rotated in the protruding direction,
The loading portion 13 is projected from the entire surface of the viewing device 1. When the protrusion of the loading portion 13 is completed by the position detection switch (not shown), the loading motor 43 is stopped. To take out the cartridge 53, after removing the cartridge locking claw 32 on the upper surface of the loading section 13, two fingers are slid into the U-shaped groove 31 on the side surface of the loading section 13 and the cartridge 53 is picked out.

Next, with reference to FIG. 10, a main part of the control section of the viewing device 1 according to the present invention will be described. Photometric sensor 7
6 is fixed at a position where it does not block the imaging light flux,
The brightness of the image-side surface of the film 52 illuminated by is measured, and the data is output to the aperture controller 75. The diaphragm control unit 75 controls the light quantity by the diaphragm 74 so that the light quantity incident on the image sensor 79 does not become too large or too small due to variations in the film density due to the light source 82 and exposure. Inject an appropriate amount of light.

The control unit 50 reads the states of the switches 4 and 8 to 12 and outputs a control signal to each block. At the time of loading, the film feeding unit 14 pushes out the film 52 from the cartridge 53 and winds it on the spool 27. At the time of performance, panning by one frame feed and film feed is performed, and at the end of the performance, the film 52 is moved to the cartridge 5
Instruct to rewind into 3. In order to read / write magnetic information on the film 52 with respect to the magnetic head controller 15, the magnetic head 40 is pressed against the film 52 during film feeding. The read magnetic information is sent from the magnetic head 40 to the control unit 50. In addition, the lens driving unit 73
A control signal is output to the device so that the imaging magnification is determined from the magnetic information.

A control signal is output to the prism driving unit 78 so that the image is erected on the TV according to the vertical position / horizontal position information in the magnetic information at the time of photographing. The signal processing unit 80 converts the image signal output from the image sensor 79 into a TV signal (NTS).
C) and output.

Next, the photometry / aperture control unit will be described with reference to FIG. The light source 82 illuminates the film 52 through the aperture 68. The photometric sensor 76 is fixed at a position that does not block the imaging light flux, and measures the brightness of the portion of the film 52 photographed by the camera through the photometric lens 81. In the case of a negative film, the film density is high when the exposure during shooting is over, and the amount of light reaching the photometric sensor 76 is small. On the other hand, if the exposure during shooting is underexposed, the film density becomes low and the amount of light reaching the photometric sensor 76 increases.

The aperture controller 75 determines the aperture based on the light amount measured by the photometric sensor 76 so that an appropriate amount of light is incident on the image sensor 79. The light amount is adjusted by the diaphragm plate 83. The diaphragm plate 83 is a circular plate having an opening for limiting the light flux and adjusting the amount of light, a pattern for position detection, and a gear 87 in the peripheral portion, and is rotatable around a rotation shaft 84. For rotation, a diaphragm plate rotation motor 85 is used as a drive source, and a reduction gear 87 is used.
Through. The aperture control unit 75 includes the photometric sensor 7
An aperture having a diaphragm value obtained from the output of 6 is selected, and the diaphragm plate rotation motor 85 is controlled so that the aperture is located on the imaging optical axis. At this time, the position detection is performed by the detection pattern on the diaphragm plate 83 and the position detecting contact piece 86.

FIG. 11 is a plan view of the diaphragm plate 83 as seen from above. With reference to FIG. 11, the detection pattern 67 is formed by masking an insulating material on a conductive material, and the black portion in the drawing is the portion where the conductive material is exposed. The detection patterns 67 are located on four circles centering on the rotation axis 84. In the outermost peripheral pattern, the conductive material is entirely exposed, and the other three patterns are formed so as to correspond to the eight openings, respectively. The pattern switching portion is located at a position symmetrical with respect to the opening about the rotary shaft 84. The position detection contact 86 is composed of four leaf springs 61, 62, 63 and 64 so as to be in contact with each pattern, and is fixed so as to be in contact with the pattern at a position symmetrical with respect to the image pickup optical axis about the rotation axis 84. ing.

The diaphragm control unit 75 detects the conduction state of the outermost contact piece and the other three contact pieces, and determines the degree of rotation of the diaphragm plate 83. Further, by stopping the rotation at the pattern switching portion, the center of the opening and the image pickup optical axis are made to coincide with each other.

The operation of the viewing device 1 according to the present invention will be described below with reference to the flowchart. FIG. 13 is a schematic flow chart showing the main operation of the viewing device 1 according to the present invention.

It is information indicating whether the image was captured in or both types are mixed. If there is no information, it is # 43. If there is information, #
Move to 67.

At # 43, the information of each frame is read as the film 52 is fed, and the read information is recorded in a memory (not shown) inside the apparatus (# 45). Magnetic information is read until the counter value reaches a predetermined value K2 corresponding to the winding of all frames (# 4
7), when the counter = K2, the process proceeds to # 49. Next, the feeding motor 20 is once turned off (# 49), and the loading motor 4
3 is turned off (# 51). The feed motor 20 is rotated in the reverse direction (# 53), and the counter is used so that the final frame comes to the opening (# 55). When the positioning is completed, the feeding motor 20 is turned off (# 57), and the loading motor 43
In the normal direction to separate the film 52 from the magnetic head 40 (#
59). When the film 52 is separated from the magnetic head 40,
The loading motor 43 is turned off (# 61).

Next, the routine goes to a routine for discriminating between normal wind and prewind. Of the information of each frame read in # 43, the date information is read from the memory (# 63). The shooting order is determined based on the read date information (# 65). Based on the determination result of the shooting order, it is determined whether the normal wind and the prewind are mixed (# 67). If they are mixed, the process proceeds to # 89, and if they are not mixed, the process proceeds to # 69.

If they are not mixed, the flag NORF = 1 indicating whether or not they are mixed is set in # 69. It is determined whether it is normal wind or prewind (# 71). If it is normal, the process proceeds to # 73, and if it is pre, the process proceeds to # 79. In the case of normal, the current state is the state in which all the films are wound up. Therefore, in order to rewind the film 52, the feeding motor 20
Is reversed (# 73). It waits until the counter value reaches the counter K2 (# 75), and when the counter = K2, the feeding motor 20 is turned off (# 77). Then, in order to write information on the lead portion, the loading motor 43 is rotated in the reverse direction to bring the film 52 into contact with the magnetic head 40 (# 79). The state of the film 52 (normal or pre) is written in the lead portion 91 (see FIG. 27). As a result, at the time of the next reproduction, it suffices to read the information in the read section 91, and it is not necessary to determine the shooting order (# 41). When the writing is completed, the loading motor 43 is turned off (# 83). The loading motor 43 is normally rotated to separate the film 52 from the magnetic head 40 (# 8
5). When the film 52 is separated from the magnetic head 40, the loading motor 43 is turned off (# 87).

Next, the case where the normal and the pre are mixed in # 67 will be described. In this case, first the flag NOR
F = 0 is set (# 89). From the discrimination result of # 65, the frame to be reproduced first (the frame photographed first) is determined (# 9
1), a counter value K3 corresponding to the film feed amount up to the first frame is set in the counter (# 93). Since the current state is the state in which all the films 52 are wound up, the feeding motor 20 is reversed in order to rewind the film 52 (# 95). After waiting for the counter to count up (# 97), the feeding motor 20 is turned off (# 99) since the predetermined amount has been fed.

Next, the contents of the image pickup condition setting subroutine shown at # 5 in FIG. 13 will be described with reference to FIG.
First, the information corresponding to the frame to be imaged is read from the memory (#
101). If there is vertical position shooting information in the read information, # 1
The process proceeds to 05 (# 103). In step # 105, the prism 77 is rotated in order to erect the vertical position photograph and reproduce it. # 1 for trimming (pseudo focal length)
The process proceeds to 09 (# 107). In step # 109, the zoom lens is driven to change the magnification. In # 111, it is determined whether or not the image is for panoramic photography, and if there is, the process proceeds to # 113. #
At 113, the feeding motor is rotated in the normal direction. Then, it waits for the film 52 to be fed by a predetermined amount (# 115), and when the film 52 is fed by a predetermined amount, the feeding motor 20 is turned off (# 117). This is because, for example, in the case of a panoramic photograph, reproduction is performed from the central portion.

Next, the process shifts to the AE routine. First light source 8
2 is turned on (# 119). The light incident through the film 52 is measured by the photometric sensor 76 (# 12
1). The aperture is determined by the output from the photometric sensor 76 (# 123). The diaphragm plate rotation motor 85 is controlled so as to obtain the diaphragm determined in # 123 (# 125).

Next, the contents of the image pickup subroutine shown in # 7 of FIG. 13 will be described with reference to FIG. First CC
The accumulation control of D is performed (# 131), the accumulated charges are read and signal processing is performed (# 133). The signal-processed image data is reproduced on the television (# 135). It is determined whether or not a zoom operation has been performed during playback (# 13
7) If the zoom is necessary, drive the zoom lens (# 139). Next, it is determined whether or not a panning operation is necessary for reproducing a panoramic photograph or the like (# 141), and if necessary, the process proceeds to # 143. In # 143, the feeding motor 20 is rotated in the normal direction, the film 52 is fed, and a predetermined amount of feeding is waited (# 145). When a predetermined amount is fed, the feeding motor 20 is turned off (# 147). It is assumed that image pickup, signal processing, and reproduction are being performed even during the zooming operation and the panning.

Next, it is determined whether or not the flag NORF = 1 (# 149). If it is 1, the process proceeds to # 151, and if it is not 1, the process proceeds to # 157. In # 151, the feeding motor 20
Is turned on to feed the film 52 to the next reproduction frame. When the wind is normal, the rotation is forward, and when it is prewind, the rotation is reverse. And wait for one frame to be sent (# 153),
The feeding motor 20 is turned off (# 155).

When it is determined in # 149 that the flag NORF = 1 is not satisfied, the frame to be reproduced next is determined based on the date information as normal wind / prewind mixed (# 1).
57). A counter value K4 corresponding to the film feeding amount up to the next reproduction frame is set in the counter (# 159), and the feeding motor 20 is turned on (# 161). Switching between forward rotation and reverse rotation depending on the feeding direction. After waiting for the counter to count up (# 163), the feeding motor 20 is turned off (# 165).

Next, in # 167, it is determined whether or not the operation button 12 is turned on during reproduction. If it is turned on, the routine returns and shifts to the rewinding routine. If not turned on # 16
Move to 9. Then, it is determined whether or not the reproduction of all the frames is completed. If the reproduction of all frames is completed, the process returns. If not completed, the imaging condition setting routine (# 10
Go to 1).

FIG. 19 is a flow chart showing the contents of the subroutine shown as the rewinding subroutine in # 9 of FIG. Referring to FIG. 19, in the rewinding subroutine, first, the feeding motor 20 is rotated in the reverse direction (# 171), and the film 52 is fed toward the cartridge 53. Then, it is determined whether or not the flag NORF = 1 (# 173). If it is 1, the process proceeds to # 175, and if it is not 1, it is determined that the prewind and the normal wind are mixed in the film, and the process proceeds to # 183. If they are not mixed, it is first determined whether they are normal wind or prewind (# 175). If it is normal, the information is written in the read section 91, and therefore the process proceeds to # 177. If it is the prewind, the process proceeds to # 183, and the information is written in the read section 91. This is the same for mixed cases.

When it is determined that the film is normal in # 175, the process waits until the end of the film is detected (# 17
7) Wait until the film 52 is completely stored in the cartridge 53 (# 179). Then, the feeding motor 20 is turned off to end the rewinding (# 181).

If it is determined in # 173 that they are mixed or in # 175 that they are prewind, first, the lead portion is awaited to be detected (# 183), and when the lead portion is detected, the loading motor 43 is turned on. Reversely, the film 52 is brought into contact with the magnetic head 40 (# 185). Then film 52
Write the information in (# 187). This information is prewind, mixed information, and the like. Then, it waits until the end is detected (# 189), the loading motor 43 is turned off, and the film 52 is separated from the magnetic head 40 (# 191). Wait until the film 52 is completely stored in the cartridge 53 (#
193), the feeding motor 20 is turned off to end the rewinding (# 195).

In the above description, the feeding state of the film 52 is mentioned as the information to be written in the lead portion, but other information such as the reproducing method may be recorded. Also, during normal wind, recording is performed before reproduction, but like during prewind, recording may be performed during rewinding (at the end of reproduction) to shorten the time until reproduction. Further, it is not the lead portion 91 that is used for recording, but a magnetic track is provided in advance on the film 52 for this ornamental device,
It may be recorded there.

FIG. 20 is a flow chart showing the contents shown as the film eject subroutine in # 11 of FIG. In this case as well, the mechanical sequence by the driving of the loading motor 43 is as described above, and therefore its explanation is omitted. In the film eject subroutine, first, the loading motor 43 is normally rotated to open the cartridge loading unit 13 (# 197). When the cartridge loading unit 13 is opened by a predetermined amount (# 199), the loading motor 43 is turned off (# 2).
01). When the operation button 12 is turned on in this state, the cartridge loading unit 13 is stored and the above operation is repeated.

Although the above description uses the area sensor as the image pickup device of the image pickup unit 19, the case where a line sensor is used will be described next. FIG. 21 is a perspective view of the viewing device 1 when a line sensor is used. Compared with the case of the area sensor of FIG. 3, the prism 18 becomes unnecessary except that the image sensor is changed to the line sensor. This is because in the case of a line sensor, when scanning the entire area, the image data is taken into a separately provided memory each time, and the entire area is memorized and then reproduced. Therefore, image rotation is possible by controlling addressing when outputting data from the memory. Since a line sensor is used, the film 5
The withdrawal amount of 2 can be shortened (for example, the width of the line sensor + the amount of magnetic reading). The contents will be described with reference to FIG. As shown in FIG. 22, the size of the aperture aperture 68 that allows the light from the light source unit 16 to pass through is made shorter than that of the area sensor so as to correspond to the line sensor. As a result, the area occupied by the film feeding unit 14 is reduced, and the size of the entire apparatus can be reduced.

Next, the flow chart of the operation shown in FIG. 13 when the line sensor is used will be described.
Only the parts different from the area sensor will be described below. Also, since the mechanism relating to film loading and feeding is the same, its explanation is omitted.

FIG. 23 shows the case of using the line sensor.
3 is a flowchart showing the contents of the imaging condition setting subroutine shown at # 5 in FIG. Similar to # 101 in FIG. 17, the image pickup frame information is read from the memory (# 211), and it is determined whether trimming shooting or panoramic shooting is performed (# 2).
13). For trimming or panoramic shooting #
In step 215, the film is fed according to each shooting, and the reproduction area is determined. Next, the AE routine is entered, but since the contents are the same as those in FIG. 17, the description thereof will be omitted.

FIG. 24 is a flow chart for explaining the contents of the image pickup subroutine shown at # 7 in FIG. First, charge accumulation is started using the line sensor (# 22
3), wait until the charge accumulation is completed (# 225). Then, the feeding motor 20 is turned on and waits for the film 52 to be fed for one line of the line sensor (# 227, 22).
9). When it is fed, the process proceeds to # 231. Although scanning is performed by feeding the film 52 in this manner, the line sensor may be moved. Further, after feeding for one line, whether or not to turn off the motor is determined by the relation between the feeding time and the accumulation time. In # 231, the fetched data is signal-processed and stored in a memory (not shown). Then, it is determined whether or not one frame has been scanned (# 23
3) If not completed, the process returns to # 223, and if completed, the process proceeds to # 235 to reproduce the signal-processed image data on the television (# 235). It is determined whether or not a zoom operation is performed during reproduction and zooming is necessary, or panning is necessary when reproducing a panoramic photograph or the like (# 237), and if necessary, the process proceeds to # 239. In # 239, the address of the memory is controlled to change the reproduction area. Then flag N
It is determined whether ORF = 1 (# 241). If it is 1, the process proceeds to # 243, and if it is not 1, the process proceeds to # 249. #
At 243, the feeding motor 20 is turned on to feed the film 52 to the next reproduction frame, and wait for the inter-frame feeding (# 2
45) When the feeding between the frames is completed, the feeding motor 20 is turned off (# 247). When the flag NORF = 1 is not set in # 241, the frame to be reproduced next is determined from the date information as normal wind / prewind mixed (# 249), and the counter value K corresponding to the film feed amount up to the next reproduction frame is determined.
4'is set in the counter (# 251). The difference from K4 in the case of the area sensor is that the feeding amount for one frame must be added or subtracted depending on the position of the line sensor. Then, the feeding motor 20 is turned on (# 253). Switching between forward rotation and reverse rotation depending on the feeding direction. Then wait for the counter to count up (#
255), when the feeding is completed, the feeding motor 20 is turned off (# 257). Then, it is judged whether or not the operation button 12 is turned on during the reproduction (# 259), and if it is turned on, the process returns to shift to the rewinding routine. If not turned on #
In step 261, it is determined whether or not the reproduction of all the frames is completed. If the reproduction of all frames has been completed, the program returns, and if not completed, the program moves to # 211 (imaging condition setting routine) shown in FIG.

FIG. 25 and subsequent figures show the positions of magnetic tracks on the film 52. In the above embodiment, the information determined by the viewing device 1 of the present invention is recorded in the lead portion 91 of the film 52, but it may be recorded in another position. In FIG. 27, information is recorded on the magnetic track TR0 provided in the lead portion 91 (the above-mentioned embodiment). In FIG. 27, the magnetic track T
R1 is a magnetic track from which information is read and written at a photo lab, and magnetic track TR2 is a magnetic track from which image information is read and written at a camera.

In FIG. 25, the information determined by the viewing device 1 is recorded on the magnetic track TR2 for the camera. That is, in the case of FIG. 25, the viewing device 1
After the camera information is read in and the shooting conditions and the like are determined, rewriting is performed again on the magnetic track TR2.

FIG. 26 is a diagram showing another embodiment regarding the position of the magnetic track on the film 52.
This is an example of the case where the recording unit TR3 for the viewing device 1 is provided between the R2s. In addition, you may make it provide the magnetic part for the viewing apparatus 1 in the place other than the said place. For example,
It may be provided above or below the camera track TR2, or above or below the laboratory track TR1.
