Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a photographing device having a detachable processor unit with a developing function.

Conventionally, when photographing on microfilm and developing it, the method used was to photograph one roll of film with a microfilm camera, and then take it out of the camera and process it in a processor after photographing one roll. I was picking.

However, according to this method, after a roll of film is photographed, it is processed in a processor such as a developing device, so the work time from photographing to processing is long, and in terms of operation, it is difficult to load the film into the camera. There is a problem in that the work becomes cumbersome because of the steps involved in photographing, taking out the film from the camera, and loading the film into a developing machine. In order to solve this problem, a so-called processor camera is known as a photographing device that performs continuous processing from photographing to developing by simply loading the film once. In this processor camera, the film exposed in the exposure section is then sent to a processor with functions such as development, where it is developed, washed with water, and dried, and then wound onto a take-up reel. There is. Such a processor camera cannot be used as a normal camera without a developing function, and if you only want to take pictures, you must have a normal camera separate from the processor camera, and you have to use two types of cameras. The drawback is that it is expensive to prepare. In order to eliminate this drawback, a camera is known in which a processor is attached to and detached from the camera so that one camera can be used in two ways.

By the way, when a long roll of film is loaded into the film supply chamber of a camera, there is fog over a predetermined length from the leading edge of the film, so generally before taking a picture, it is necessary to
I am trying to feed the film 1.5m long without taking any pictures. In a processor camera, the film path from the camera's film supply chamber to the processor's film winding section is long, so when using it as a processor camera, the amount of film feed may be small, but if the processor is removed from the camera, If the amount of film feed is reduced when used as a processor camera, there is a problem that the subject will be exposed to the fogged portion of the film, making it impossible to accurately photograph the subject. On the other hand, if you set the film feed amount to the amount required when using it as a camera, you will end up needlessly feeding the film when you use it as a processor camera, and in any case, you will not be able to use one processor camera. Problems arise when used in two ways.

The present invention solves the above-mentioned problems and provides a photographing device in which the necessary minimum amount of empty feed is automatically performed.

The present invention will be explained below using specific examples shown in the drawings. Figure 1 shows the entire processor camera applied to the present invention, and in the figure, each unit that can be attached to and detached from the main body base is removed, but each unit is configured to be detachable from the main body base. The device is supported by the main body base, and exerts its function by being attached to the main body base.
1 is a camera unit, which includes a raw (unexposed) film supply section, an exposure (photographing) section,
It has a film drive section, a film winding section, a photographing lens, etc., and details of this unit will be described later. Reference numeral 2 denotes a processor unit, which includes a liquid processing section such as a developing section, a film driving section, a drying section, a winding section, a processing liquid temperature control section, a processing liquid circulation section, and the like. Camera unit 1 and processor unit 2
are electrically and mechanically connected to the support unit 3 by connectors 4, 4'-5, 5' which are configured to be detachably attached. The support column unit 3 is configured to be detachably attached to the main body base 6, and is electrically and mechanically connected to the main body base 6 by a connector 7. The support unit 3 has a supply indicator lamp 9 which is turned on as required.

The main body base 6 has a subject mounting section 10 and a control section 11, and switches having various functions are arranged on the front panel of the control section 11. S ₁ is the power switch, S ₂ is the supply switch for feeding a certain amount of film, and S ₃ is for selecting whether the counter on the front of the camera unit will automatically advance or always keep the same content. _S4 is a switch that selects whether or not to capture the search mark and the contents of the counter mentioned above on the film. S5 is a switch that selects whether or not to record the search mark on the film and the contents of the counter described above. By switching this, _S5 uniquely changes the exposure time to the initial setting time. This is an exposure magnification switch that changes the exposure magnification. 14
is a light receiving section that measures the illumination light that illuminates the subject document, and this controls the shutter opening time. 15 is a light source unit that illuminates the subject;
This unit is configured to be detachably attached to the main body base 6, and is electrically and mechanically connected by connectors 16, 16'.

A photographing flat sheet 20 for placing a subject is placed at a predetermined position on the subject mounting section 10 of the main body base, and a frame 21 indicating a photographable range is attached to the surface of the sheet 20.

If a subject is placed within this frame, the entire surface of the subject will be photographed. Further, various switches are arranged on the subject mounting section 10. S ₇ is a space switch to advance the film one frame at a time, S ₈
is the shutter switch, and S ₉ is a switch that selects whether or not to advance the counter automatically. It temporarily reverses the setting state of S ₃ (only when the shutter is pressed once), and after pressing the shutter, switch
This is a switch that temporarily reverses the state of the counter so that it returns to the setting state of _S3 .
Note that the switches S ₂ , S ₇ , S ₈ , and S ₉ are self-reset type switches, and the other switches S ₁ , S ₃ , S ₄ , and S ₅ are lock type switches.

In this processor camera, camera unit 1 and processor unit 2 are connected to support unit 3.
When only the camera unit 1 is attached to the support unit 3 connected to the main body base 6, it can be used as a microfilm camera without a processor function. By preparing various camera units with different photographing magnifications, it is possible to replace and use the camera units according to the photographing magnification. However, in this case, a sheet 20 indicating the shooting range according to the shooting magnification of each camera unit is used.
Since it is necessary to change the position of the frame 21, the sheet 20 is replaceable, and a sheet 20 suitable for the camera unit can be used.

Next, details of the camera unit will be explained with reference to FIGS. 2 to 7. In FIG. 2, 101 is the upper body of the camera unit 1, which is divided into a front chamber and a back chamber by a partition wall parallel to the plane of the paper. The front chamber forms a film storage area and a passage, and the back chamber is provided with a mechanism for operating a camera unit. Furthermore, the front chamber has a wall in the center, and the right side is the film supply chamber 1.
02, the left side is divided into a film winding chamber 103, a film supply chamber 102 and a film winding chamber 10.
There is an exposure section 104 for photographing approximately halfway down.
A film passage 105 connecting the film winding chamber 103 and the processor unit 2 is formed at the upper outside of the film supply chamber 102, and a connecting pipe 106 is provided at the connection portion of the passage with the processor unit. In the film supply chamber 102, a supply shaft 107, on which a reel 108 wound with a raw film is mounted approximately in the center, is rotatably installed in the upper body 101 with a moderate amount of frictional resistance. The supply shaft 107 and the reel 108 are prevented from rotating relative to each other, for example, by fitting a square hole into a shaft having a square cross section. Supply chamber lever 10
9 is for detecting the remaining amount of film wound on the reel 108, and has a shaft 110 at one end that is rotatable with respect to the upper body 101 and biased by a spring in the counterclockwise direction; At the other end, reel 108

is pressed against the capstan roller 112.
Reference numeral 117 denotes a film winding shaft, and when the camera is used simply as a camera without using a processor unit, it is naturally installed in the center of the film winding chamber at the position indicated by the broken line 117' as shown by the two-dot chain line. The camera unit is connected to the processor unit (a reel is attached to the take-up shaft), and when used as a processor camera, it is separated from the coupling hole 118 and evacuated to a corner 117 of the film winding chamber. When used as a processor camera, this film winding chamber has a winding shaft 117 which is used as a film loop chamber (buffer chamber).
Needless to say, consideration has been given to making it easy for the user to attach and detach the connector to and from the coupling hole 118. A film guide roller 119 guides the film into the winding chamber 103 through the film passage 105 and the connecting pipe 106 toward the processor unit. Below the upper fuselage 101 is the lower fuselage 1.
20 is attached, and an aperture box 121 is fixed approximately at the center of the lower body 120. An aperture plate 123 is attached to the top surface of the aperture box, and a pressure bonding plate 124 is attached to the lever 124 for pressing the film against the plate during exposure and holding the film in a predetermined position and flat.
It is loosely attached to a pin 126 protruding from one end of 25. The lever 125 has a shaft 12 at the other end.
7 is firmly fixed, and the shaft 127 is fitted into a hole provided in the bulkhead of the fuselage and is biased to rotate clockwise by a spring provided in the back chamber.
As shown in FIG. 4, the aperture plate 123 has an aperture 123 that determines the shooting range of the subject.
A window 123b for imprinting a mark and a window 123c for imprinting a frame number are provided in the frame. Second
In the figure, 128 is a light emitting diode as a light source for mark imprinting, and is located directly below the mark imprinting window 123b. In the lower body 120, a photographing lens 129 is fixed below the aperture 123a. A shutter blade 130 is disposed between the aperture 123a and the photographing lens 129, and the shutter blade 130 is arranged between the aperture 123a and the photographing lens 129. It blocks out the light heading towards you. The shutter blade 130 is the lower fuselage 120
The shutter solenoid 132 is rotatably mounted around a shutter shaft 131 protruding from the main body, and when exposing the film, a shutter solenoid 132 is attracted by a signal from the control section 11 of the main body base.
The light escapes out of the effective optical path of the photographing lens 129. 133
is the return spring of the shutter blade. 134 is a decimal counter for counting the number of photographed frames, and a 6-digit number is displayed on 6 reading character wheels 136 lined up in the axial direction. The counter can not only be read from a counter reading window 140 provided in a part of the bottom cover 139. If necessary, the same number displayed on the reading window can be imprinted adjacent to the image on the film as a frame number 142 (see FIG. 5). 137 is a number imprint ring made of translucent resin material for this purpose.
Six pieces are lined up in the axial direction, corresponding to the digit numbers. Further, numbers from 0 to 9 are printed in a negative state (the text part is transparent and the surrounding part is opaque) at equal intervals on the outer periphery of each ring. 138
is a lamp for illuminating the ring 137 from inside and imprinting characters on the film;
It blinks due to the signal from 1. 145 is lamp 1
Of the letters on ring 137 illuminated by 38,
A light-shielding plate with a window that allows only light from the numbers in a predetermined position to pass through prevents unnecessary leakage light from reaching the film. The light passing through the window of the light shielding plate 145 passes through the first mirror 146, the second mirror 147,
The image is photographed on the film F through the window 123c of the aperture plate 123 through an optical system such as an imaging lens 148', and is imprinted as a frame number 142 between the frames. Reference numeral 135 denotes a drive wheel that drives the reading character wheel 136 and the number imprinting ring 137, which is a ratchet wheel divided into 10 parts of the circumference and gears provided in the reading character wheel 136 and the number imprinting ring 137, which are in mesh with each other. It is configured. Needless to explain, each gear has the same number of teeth. A part of the circumference of the gear of the reading character ring 136 is located on the bottom cover 1.
39 and can be rotated by the user's fingertips, allowing the user to set the number on the counter to any number at any time. A connector 148 relays electrical signals from the control section 11 to the camera unit 1, and is fixed to the lower body 120 via a support 149. FIG. 3 shows the back room behind the camera unit in FIG. 2. In FIG. 3, M is a drive motor, 150 is a pinion attached to the output shaft of the drive motor, and 151 to 154 are drive motors M.
A drive pin 155 and an operating cam 156 of the pressure bonding plate 124 shown in FIG. 2 are integrally formed in the final stage gear 154. A micro switch 157 is operated by a pin 155 to switch every time the gear 154 rotates once, and sends a signal to the control section to control the gear 154 to stop after one rotation. When the gear 154 rotates once, the connecting rod 158, which has one end attached to the drive pin 155, rotates the right gear 167 by 60 degrees clockwise, as will be described in detail later, and is fixed to the shaft 169 of the gear 168 by meshing with it. The film F is fed by one pitch (FIG. 5p) through the capstan 113' (FIG. 2). Furthermore, gear 1 is connected to gear 168 via gear trains 170 to 172.
73 and a cam wheel 174 integrally formed therewith. The rotation of the cam wheel 174 turns on and off the micro switch 175 for detecting film feed, and the frequency of the turn on and off is set to one time per 10 mm of film feed. That is, in this embodiment, the diameter of the capstan 112 is 19.1 mm.
One revolution of the cam gear feeds the film 60mm. On the other hand, the protrusion on the outer periphery of the cam ring 174 that presses the actuator of the micro switch 175 is 8
One rotation of the cam ring 174 causes the micro switch 175 to be turned on and off eight times. Therefore, gear 168 and gear 173 are connected by gear train 170 to 172.
The rotation ratio is set to 8:6. 4 and 7 show a mechanism for feeding the film F intermittently at regular intervals. FIG. 7 is a view of FIG. 6 viewed from the direction of arrow A. As mentioned above, in FIG. 6, the gear 154 is rotated in the direction of the arrow by the drive motor M via the reduction gear train, and is stopped after completing one rotation due to the cooperative action of the pin 155 and the micro switch 157 (FIG. 3). . On the other hand, a ratchet wheel 162 is integrally fixed to the shaft 163 of the right gear 167, and one end of a swing arm 159 is rotatably fitted. A pin 158' is installed at the other end of the swinging arm 159, and the ratchet pawl 1
60 serves as the fulcrum axis. Ratchet claw 160
The tip of the ratchet wheel 162 is always pressed against the outer periphery of the ratchet wheel 162 by the action of the torsion spring 161. A ratchet pawl 164 having the same shape as this ratchet pawl is connected to a fixed shaft 164 protruding from the upper body 101.
6 and is pressed against the outer periphery of the ratchet wheel 162 by the action of a torsion spring 165, thereby prohibiting the ratchet wheel 162 from rotating in reverse. Pin 158' on swing arm 159 and gear 154
The upper portions 155 are fitted into holes at both ends of a rigid connecting rod 158, respectively. With the above configuration, when the gear 154 rotates once as described above, the swing arm 157 reciprocates once in the range of arrow a (approximately 65 degrees), and the ratchet wheel 162 moves at an angle of one tooth (approximately 65 degrees).
degree). More specifically, in the first half-turn (lower half) of pin 155, pin 1
58' moves to the right, but since the ratchet wheel 162 and the ratchet pawl 160 slide against each other, the ratchet wheel 162 remains stationary. The subsequent half-turn of pin 155
8' moves to the left within the range of arrow a, but at this time the tip of the ratchet pawl 160 engages with the teeth of the ratchet wheel 162 to rotate the ratchet wheel 162 clockwise. This rotation is transmitted to a gear 168 that meshes with a gear 167 that is integrally connected to the shaft 163 of the ratchet wheel, and keeps the film F pressed against the capstan roller 113' provided on the shaft 169 of this gear at a constant level. I will send the amount. In the field of 16 mm film photography used in this embodiment, there are various film feed amounts for each shot, but feeds of 10 mm and 11.75 mm are common. Therefore, in this embodiment, the above-described structure is adopted in order to easily meet the requirements for both feed amounts. In other words, assuming that the outer diameter of the capstan roller is 19.1 mm and the number of teeth of the ratchet wheel is 6, the ratio of the number of teeth of gears 167 and 168 is 1:1 (=50:50) when the feed pitch is 10 mm, and the feed amount is 1:1 (=50:50). In the case of 11.75 mm, the above objective can be achieved by selecting 1:1175 (=46:54).
Returning to FIG. 3, 176 is the pinch roller 113
(Fig. 2), the pin 177 is implanted at one end of the lever, and the lever 1 engaged with the pin.
78, the shaft 116 is biased counterclockwise (clockwise in FIG. 2) by a tension spring 179. 180 is a pressing lever of the pressure bonding plate 124 (FIG. 2), and a pin 181 is implanted at one end of the lever.
A lever 182 engaged with the pin and a tension spring 183 bias the shaft 127 counterclockwise (clockwise in FIG. 2). Reference numeral 184 denotes a pressure release lever that swings about a shaft 185 protruding from the body 101 as a countershaft, and has a roller 186 at one end that contacts the outer peripheral surface of the cam 156. This lever 184 is
During a period corresponding to approximately 1/2 rotation of gear 154, cam 1
56 is rotated counterclockwise via a roller 186, and the other end is rotated counterclockwise by the large outer diameter portion of the lever 180.
80a and against the spring 183, the shaft 127
Turn clockwise to release the film from the pressure bonding plate 124 against the aperture plate 123.
This operation is performed only when the film F is in the feeding state, and when the film is stationary, the film is always moved to the aperture plate 1 by the pressure bonding plate 124.
23. A lever 187 is pivotally supported by a shaft 188 protruding from the body 101, and pins 187a and 187b are implanted in a portion of the lever to be slidably fitted into the elongated holes of the levers 178 and 182, respectively. The lever 187 is attached to the shaft 18 by a torsion spring 189.
8 as a fulcrum, but is restrained at the position shown in FIG. 3 when the opening/closing lid (not shown) of the film chamber on the front side is closed.
When the opening/closing cover is opened to load film into the film supply chamber, the lever 187 is released from its restraint and is rotated counterclockwise by the torsion spring 189, which causes the levers 176 and 180 to be moved clockwise to release the pinch. The roller 113 and the pressure bonding plate 124 are each retracted from the trajectory of the film F, so that the film can be easily loaded. Reference numeral 190 is a film remaining amount alarm cam that is connected to the remaining amount detection lever 109 (second
It is fixed to the shaft 110 in the figure). The fan-shaped member 193 on the right side is pivotally supported by a pin 192 protruding from the fuselage 101, and a remaining amount scale plate 194 is attached to the arc-shaped side surface of the fan-shaped member 193.
It is designed so that it can be read through a window glass 201 provided in the window. Remaining amount cam 190, fan-shaped member 193
Pins 191 and 195 are installed respectively in the
A connecting rod 196 having a hole in which the pin is rotatably fitted is suspended at both ends. A pin 196a is installed approximately in the center of the connecting rod 196, and is biased to the right by a tension spring 198 hooked to the pin.As a result, the remaining amount cam 190 and the fan-shaped member 19
3 receives a clockwise rotational force. Remaining amount cam 110
The remaining amount detection lever 109 shown in FIG. 190
The position of the fan-shaped member 193 in the rotational direction is determined. That is, the amount of rotation of the remaining amount cam 190 and the fan-shaped member 193 is determined according to the winding diameter of the film on the reel 108. Therefore, the remaining amount of film in the film supply chamber 102 can be known by reading the remaining amount scale plate 194 through the window glass. Furthermore, when the winding diameter of the film becomes less than a predetermined value, the remaining amount cam 190 switches the contacts of the micro switch 200 and sounds the buzzer 202 to issue an alarm sound, indicating that there is not enough film left in the film supply chamber 102. Let me know when you're summer. Reference numeral 199 denotes a lever supported by a shaft 203 protruding from the body 101, and a pin 199 that fits into a hole at one end of the lever 197 is attached to a part of the lever.
A is planted. The lever 199 is biased by a torsion spring 204 to rotate counterclockwise about the shaft 203, but when the opening/closing cover (not shown) of the film supply chamber on the front side is closed, is restrained in the position shown. When the opening/closing lid of the film supply chamber is opened to load film, the lever 199 is released from its restraint and is moved counterclockwise by the torsion spring 204. As a result, the lever 197 is pulled to the left and the elongated hole 1
A pin 196a comes into contact with the right end of 97a, and the connecting rod 196 is also moved to the left. Therefore, the rotating shaft 11
0 rotates counterclockwise, the remaining amount detection lever 109 moves to the outside of the outer circumference of the reel 108. Therefore, the reel can be easily attached to and detached from the film supply shaft 107. Reference numeral 206 denotes a coil spring, the hooks at both ends of which are hooked onto fixing pins 207 protruding from the body 101, and the central portion of which is wound around a V-pulley 205 fixed to the film supply shaft 107. The frictional resistance between the spring and the V groove of the V pulley 205 provides an appropriate back tension when the film is pulled out;
Prevents film sagging. Reference numeral 208 designates the drive shaft of the counter 134 shown in FIG. 2, and when it is rotated approximately 40 degrees clockwise from the outside, the lowest drive wheel 135 of the counter, the reading character wheel 136, and the number imprinting ring 137 move, respectively. Rotates 36 degrees (1/10 rotation) and advances one number. Next, when the external driving force is released, it returns to its original position by the force of a spring (not shown). By doing the above 10 times, the second digit character ring becomes 36, and after 100 times, the third digit character ring becomes 36.
It's starting to move more and more. Since these mechanisms are conventionally known, their explanation will be omitted. 209,
210 and 211 are members for applying power to the counter as described above, and 209 is a counter drive lever 210 that is integrally connected to the drive shaft 208.
is a pin protruding from the push rod 211, which is rotatably fitted into a hole provided at one end of the counter drive lever. One hook of a tension spring 212 is hung on a pin 211a at the right end of the push rod 211, and the other hook of the tension spring 212 is hung on a pin 209a at the center of the counter drive lever 209. For this reason, the push rod 211 attempts to rotate clockwise about the shaft 210, but its left end abuts the lower side of the film drive pin and remains in the position shown.

When the motor M of the camera unit rotates in response to a command from the control unit 11 of the main body base, the pin 155 rotates once around the rotation axis of the gear 154, but in the first half rotation, the pin 155 rotates through the connecting rod 158.
58' moves to the right in an arc of about 65 degrees about axis 163. At this time, the left shoulder of the push rod 211 engages with the pin 158', pushing the push rod 211 to the right, and as a result, the counter drive lever 209
drives the counter drive shaft 208 clockwise,
Counter 134 increments by one step. As the motor continues to rotate further and the pin 155 shifts to the upper half rotation, the pin 158' changes to the leftward movement, and the push rod 211, counter drive lever 209, and counter drive shaft 208 are activated by the return spring (not shown). Due to the action, it returns to its initial state,
Prepare for future reactivation. 213 is a counter release lever, which is used to advance the film without advancing the counter. That is, the lever 213 is pivotally supported at its center by a support shaft 214 that protrudes from the lower body 102, and is held by a tension spring 215 so that its right end is horizontal. The distal end portion 213b of the release lever extending further downward is connected to the plunger of the solenoid 216. Now, if it becomes necessary to feed the film F without advancing the counter, the solenoid 216 is also energized at the same time as the motor M is energized. solenoid 216
When the plunger is energized, the plunger is attracted, and the counter release lever 213 is rotated to the position shown by the two-dot chain line. Due to this rotational movement, the right tip 213a of the lever hooks the bent portion 211b of the counter push rod 211 and lowers the push rod 211 to the position shown by the two-dot chain line.
Even when the pin 8' is moved to the right, the pin does not engage with the shoulder portion of the push rod 211. Therefore, the motor M can feed the film without stepping the counter 134.

FIG. 8 shows the state in which each unit is connected to the main body base. Camera unit 1 is connecting tube 1
It is connected to the film inlet of the processor unit 2 by 06, so that the film passages of both are connected.
Further, the camera unit and the processor unit are electrically connected to the main body base 6 by connecting the connector 148 of the camera unit to the connector 4 of the support unit, and the connector 5' of the processor unit to the connector 5 of the support unit.

When the arm 228 shown in FIG. 13 is in the position shown by the solid line, it is in the on state. When there is more than a predetermined amount of film loops in the film winding chamber of the camera unit, the movable guide roller 229 is at the position indicated by the broken line 229'. This is because the film slackens due to the presence of the film loop, so the tension spring 2

If the number of film loops in the camera unit's take-up chamber is less than a predetermined amount, and the film is being fed by the film drive roller of the processor unit, a strong tension will be applied to the film, causing the film F to advance. As a result, the arm 228 rotates counterclockwise, and the roller 229 moves from the broken line position to the solid line position. As a result, the micro switch 234 is activated, indicating that the number of film loops has decreased. emits an electrical signal indicating the

The light-shielding lid is opened when loading film into the processor unit 2, for example. Reference numeral 238 denotes a heating block for controlling the temperature of the developing solution. A narrow liquid flow groove is formed inside this block, and the developing solution is heated to a predetermined temperature while passing through this groove. 239 is a cartridge type heater for heating the block, and 240 is a thermoswitch that cuts off power to the heater when the block is overheated. 241 is a drive mechanism; 242 is a pump mechanism for supplying the processing liquid from the processing liquid storage container to the developing device and the washing device; the pump mechanism is driven by the drive mechanism 241;

Next, details of the drive mechanism will be explained with reference to FIG.

All parts of the processor unit are driven by a single motor _M2 . That is, a blowing fan for drying the film, a pump mechanism for circulating the processing liquid, a film drive roller, and a film winding section in the processor unit are driven by this motor _M2 . The motor _M2 is a double-shaft motor, with a Sirotskov fan 234 for blowing air attached to one shaft, and a pinion 244 for deceleration attached to the other shaft. pinion 244
The rotational force is transmitted to the film drive gear 252 via reduction gears 245 to 251.

The reduction ratio of each gear is set to 1/10 with two-stage reduction. The second stage gear 246 is fixed to the pump drive shaft 253, and the fifth stage gear 246 is fixed to the pump drive shaft 253.
9. A small gear 250 is provided on a speed switching shaft 254, and a film drive gear 252 is fixed to a film drive 255.

Further, a pump drive gear 256 is fixed to the pump drive shaft 253, a ladder wheel 260 is fixed to the film drive shaft 255, and a speed switching shaft 256 is fixed to the film drive shaft 255.
4 is rotatably provided with a slack gear 258. The fifth stage gear 249 is a one-way clutch 259
It is provided on the speed reduction switching shaft 254 via the speed reduction switching shaft 254, and when rotated counterclockwise, it meshes with the speed switching shaft 254 and transmits power to the shaft. A left-handed clutch spring 261 is attached to the outer periphery of the loose gear 258.
are engaged and the pawl at the end of the clutch spring is hooked onto the control ring 262, and when the control ring stops rotating, the clutch spring is loosened and disengaged from the loosening gear 258. Therefore, clutch spring 2
61 is fitted with the speed switching shaft 254, but when the rotation of the control ring 262 is stopped, the shaft 254
A slip occurs between the spring 261 and the shaft 254, and the shaft 254 rotates freely relative to the slackening gear 249.

On the other hand, when the control ring 262 is rotated, the loosening gear 258 and the clutch spring 261 are tightened, and the clutch spring and the shaft 254 are coupled together. Therefore, by controlling the rotation of control ring 262, transmission of the rotational force of slack gear 258 to shaft 254 can be controlled. FIG. 11 shows a mechanism for controlling the control ring, in which the control ring 262 is provided with a protrusion 262', and by hooking a control lever 263 to this protrusion, the rotation of the control ring is stopped. be able to. A feed rate switching solenoid 265 is attached to the end of the lever 263, and when the solenoid is energized, the lever 263 rotates, causing the protrusion 26 of the control ring to rotate.
2' and the lever 263 are disengaged. When the solenoid is de-energized, the lever 263 is returned to its original position by the tension spring 266, and the lever and control ring protrusion 262' are reengaged, stopping rotation of the control ring.

Now, when the rotation of the control ring 262 is stopped, the slack gear 258 is rotated by the fourth stage gear 248, but this rotation is caused by the clutch spring 2.
61 and the slack gear 258 are in a free rotation state, so the speed is not transmitted to the speed switching shaft 254.

Therefore, gear 2 meshing with reduction gear 248
49 is transmitted to the speed switching shaft 254 via a one-way clutch 259, a small gear 250 fixed to this shaft rotates, and a film drive shaft 255 rotates via gears 251 and 252.

Therefore, the number of rotations of the film drive shaft 255 decreases to 1/(√10) ⁷ =1/3162 of the number of rotations of the motor M ₂ . (becomes slower).

Next, the solenoid 265 is energized and the protrusion 262'
When the clutch spring 261 is disengaged from the lever 263, the clutch spring 261 loosens and the gear 258 and the speed switching shaft 254
meshes with Therefore, the rotational force of the slack gear 258 is transmitted to the speed switching shaft 254.

On the other hand, the fifth stage gear 249 is the fourth stage gear 249.
8, but the loose gear 25
8 is about 3.16 times higher than the rotation speed of the fifth gear 249, so even if the fifth gear 249 is rotating, the one-way clutch 259 does not mesh with the shaft 254, resulting in a slipping condition. The rotational force of the stage gear is not transmitted to the shaft 254.

On the other hand, the rotational force of the loosening gear 258 is transmitted to the shaft 254, and the film drive shaft 255 rotates at high speed via the gears 250, 251, and 252.

The rotation speed of the film drive shaft 255 at this time is 1/(√10) ⁵ = 1/316.2 of the rotation speed of the motor M ₂ (high speed).

That is, the drive shaft 255 is rotating at an angular velocity ten times higher than when the control ring 262 stops rotating.

Therefore, by controlling the energization of the solenoid and controlling the rotation of the control ring 262 while the motor _M2 is rotating at a constant speed, the film drive shaft can be rotated by 1:10.
speed switching can be performed.

Returning to FIG. 10, the ladder wheel 260 of the film drive shaft 255 is connected by a ladder chain to a ladder wheel 270 connected to the film drive roller and a ladder wheel 271 connected to the film winding shaft.

The film drive rollers 275, 276 are made of the same material as the capstan roller 113' of the camera unit, and have the same outer diameter of 19.1 mm. The film drive rollers 275, 276 are arranged in the winding/drying section 221 as shown in FIG. Note that there is no roller in the liquid processing section 220 for driving the film. Gears 2 are mounted on the shafts of the drive rollers 275 and 276, respectively.
75', 276' are fixed, and the drive roller 276
A cam wheel 278 is fixed to the shaft.

Therefore, the rotational force of the rudder wheel 260 is transmitted to the rudder wheel 270 via the rudder chain 272, and the two driving rollers 275, 276 are rotated via the gears 275', 276'. Further, on the outer periphery of the cam wheel 278, protrusions for operating micro switches 279 for detecting film advance are provided at six equal positions. Therefore, the drive roller 27
When 5,276 rotates 1/6, micro switch 2

5,276 1/6 rotations corresponds to feeding the film 10 mm as explained in the camera unit. 280 is a film winding shaft, and a friction plate 281 is provided on this shaft.
It rotates together with 0, but is movable in the axial direction. The friction material 28 is on the rudder wheel 271.
2 is attached, and this ladder wheel is rotatably provided with respect to the winding shaft 280.
The friction plate 281 is connected to the friction material 28 by the plate spring 283.
2, and this pressing force can be adjusted with a screw 284 provided on the shaft 280.

Therefore, the winding shaft 280 is connected to the ladder chain 272.
The driving force of the rudder wheel 271 and the friction material 28
2. It is transmitted via the friction plate 281. A film take-up reel 285 is detachably attached to the take-up shaft 280, rotates together with the take-up shaft, and winds up the developed film. Note that power is transmitted from the ladder wheel 271 to the take-up shaft via a friction plate and a friction material;
When the film is wound on the winder 85, the winding diameter of the film changes, and the film feeding speed by the film drive rollers 275, 276 and the film winding speed by the take-up reel change, so that slippage occurs between the winding shaft and the ladder wheel. This prevents the film from being cut, etc.

On the other hand, the air blowing fan 243 attached to the other end of the motor _M2 rotates at high speed due to the drive of the motor, and the air sucked in from the air intake port passes through the guide section (not shown) of the processor unit to the film drying section. lead. A heating element is provided in the middle of the drying section to send high-temperature dry air to the film drying section to easily and quickly dry the wet film after development and washing.

A film drying chamber 290 is provided with a slit-shaped opening 291 in a direction perpendicular to the direction in which the film travels, that is, in the width direction of the film.

Figures 14 and 15 show the liquid circulation pump mechanism 24.
This figure shows the details of 2.

In FIG. 14, a pump drive gear 256 fixed to a pump drive shaft 253 of the drive mechanism 241
As mentioned above, is rotating at a rotation speed that is 1/10 of the rotation speed of the drive motor _M2 . This rotational force is applied to the intermediate gear 2
95 to gear 296. gear 29
A gear 297 is fixed to the same rotating shaft as 6,
Gear 296 and gear 297 rotate integrally. This gear 297 is a crankshaft drive gear 298 ₁ , 2
98 ₂ (see Figures 9 and 15). One crankshaft drive gear 298 ₂ is connected to a similar crankshaft drive gear 29 through an intermediate gear 299 .
8 It meshes with ₃ . Crankshaft drive gear 298
₁ , 298 ₂ , and 298 ₃ are respectively fixed to a pump driving crankshaft 300 (FIG. 15). Therefore, the driving force of the drive mechanism 241 is transmitted to each pump drive crankshaft 300 via each gear.

Incidentally, a crankshaft for driving a pump is fixed to each of the gears 298 ₁ , 298 ₂ , and 298 ₃ , and there are three pumps, each of which is configured in the same way. Reference numeral 301 denotes a pin implanted at the end of the crankshaft 300 at a position offset by Y from the center of rotation.A push rod 302 is rotatably attached to this pin, and a diaphragm 303 is attached to the other end of the push rod. Fixed.

The circumferential edge of this diaphragm has an O-ring shape, and by tightening the diaphragm to the pump upper housing 304 and lower housing 305, the O-ring shaped portion serves as a seal.

The lower housing 305 is also provided with a suction pipe 306 and a discharge pipe 307, each having a one-way valve to form a pump.

Therefore, when the crankshaft drive gear ₂₉₈₁ rotates, the eccentric pin 301 causes the push rod 302 to rotate.

moves up and down. Therefore, the suction pipe 306 and the discharge pipe 3
07, the processing liquid enters the suction pipe 306 in the direction of arrow a, moves to the discharge pipe 307, exits from the discharge pipe 307 in the direction of arrow b, and finally reaches a predetermined level. liquid can be delivered to the location.

Returning to FIG. 8 again, the liquid processing section 220 is connected to the developing device 3.
50, and has water washers 351 and 352. Details of the developing device 350 are shown in FIG. Note that the water washers 351 and 352 are also configured in the same manner as the developing device, so a description thereof will be omitted. In Figure 16, 3

Reference numeral 66 indicates a film guide roller provided at the entrance and exit of the developer tank, and 367 indicates a film guide roller which is normally disposed within the liquid reservoir 361 and is movable up and down. When loading the film, this roller 367 moves to the position 367' shown by the broken line to facilitate the initial loading of the film into the liquid processing section, and after loading the film, moves to the position shown by the solid line to immerse the film in the liquid in the container 361. invite. Reference numeral 370 denotes a nozzle pipe for supplying a developer to the film, and the developer supplied by the pump mechanism described above is discharged from the nozzle. The film F is placed on the guide rollers 365, 3 with the emulsion side facing up.
67,366 and is transferred from left to right.

After the film F exposed by the camera unit passes through the film detector of the processor unit, it first enters the liquid reservoir container 361, and the emulsion surface uniformly contacts the developer in the container 361. Then the slope 362
A developing solution is sprayed onto the film emulsion surface by the nozzle pipe 370 to accelerate development. in this case,
Since the developer is sprayed in the opposite direction to the direction in which the film travels, development is further accelerated compared to other developing methods. Therefore, the film can be sufficiently developed with a relatively short film transport distance, and if the film transport speed is the same, the apparatus can be made more compact than the conventional apparatus.

The developer blown out from the nozzle pipe 370 flows downward along the film surface, moves below the slope 362, and enters the liquid reservoir. The liquid overflowing from the edge 361' of the liquid reservoir container 361 is drained from the drain port 363 to the eighth
It returns to the storage container 380 in the figure and is pumped up again, after which this process is repeated. In addition, in FIG. 8, 381 and 382 are washing liquid storage containers. In the above embodiments, a one-bath developing and fixing solution is used as the developer. A developing device and a fixing device may be provided separately. Returning to FIG. 8 again, in the same figure, the light receiving unit 14 that measures the illumination light illuminating the subject has a diffusion dome 400, and a light receiving element 40 is mounted on the back of the dome 400.
1, and this light receiving element generates an electrical signal proportional to the intensity of illumination light. This electrical signal changes the operating time of the shutter solenoid 132 and controls the opening time of the shutter 130, thereby constantly applying a constant amount of exposure to the film and keeping the image density on the film constant, regardless of changes in the amount of light from the illumination light source. Make it. However, the sensitivity of the light-receiving element varies due to manufacturing, so polarizing filters 410 and 411 for adjustment are placed in front of the light-receiving element so that the density on the film is always constant when a standard amount of illumination is applied. It is provided. By changing the relative angular position of these two polarizing filters 410 and 411, the amount of light transmitted can be changed.

In the figure, various switches are in the off state.

Next, the operation of the processor camera will be explained with reference to the timing chart of FIG. 17.

First, each unit is connected to assemble a processor camera, a film is loaded into the supply chamber 102 of the camera unit, and the film is wound onto the take-up reel 285 through a predetermined film transport path of the camera unit and processor unit. After setting the film correctly, first turn on the power switch _S1 at time _t1 (see A in Figure 17).
(see waveform), the relay 593 is turned on via the relay drive circuit 592 in FIG. 18, the power supply circuit 596 is activated, and power is supplied to all devices (B
Waveform). When the power supply starts, the motor _M2 of the processor unit is driven, (R waveform) the lamp of the lighting unit 15 is lit (C waveform), and the weight display lamp (565 in Fig. 18) of the control unit 11 is lit. (G waveform). This weight display lamp 565 is activated when the initial state setting circuit 572 is turned on and the photography prohibition memory 571 is reset when the power supply starts, and the temperature of the developer reaches a predetermined temperature and once the developer is rolled up. The light is turned on until the film loop in the taking chamber 103 runs out. When the photography prohibition memory 571 is reset, the AND gate _G1 is closed.
Even if you turn on the shutter switch _S8 while the weight display lamp is on, shooting will not take place. on the other hand,
Since the loop detection memory 580 is set by turning on the initial state setting circuit 572, the feed speed switching solenoid 265 is turned on via the feed solenoid drive circuit 563 (U waveform), and the film in the processor unit is fed at high speed. . In addition, when the power switch S ₁ is turned on, the heater 2 for heating the processing liquid is turned on.
39 is turned on (W waveform) and starts heating the heating block.

As the motor _M2 is driven, the amount of film in the winding chamber 103 of the camera unit decreases, and when the film loop disappears (the film in the winding chamber is tightly stretched), the loop detection switch is activated at time _t2 . 234 is turned on (S waveform), the set pulse generation circuit 526 is activated via the OR gate _G32 , the motor drive memory 524 is set, and the motor M of the camera unit is driven via the motor drive circuit 525 ( J waveform). The film is idly fed by the drive of the motor M, and the film is supplied into the take-up chamber 103. As a result, the film in the take-up chamber becomes slack and the loop detection switch 234 is turned off. When the motor M rotates by a predetermined amount, the motor stop switch 157 is turned on (K waveform), the motor drive memory 524 is reset, and the motor M is stopped. Since the motor _M2 of the processor unit continues to drive, the above operation is repeated the next time there are no more film loops in the winding chamber. Therefore, damage to the film is prevented. On the other hand, loop detection switch 2
34, the loop detection memory 580 is reset, the speed switching solenoid 265 is turned off (U waveform), and the film in the processor unit is switched from high speed to low speed.

The reason why the film feed speed of the processor unit is set to a high speed when the power is turned on and is set to a low speed when the loop detection microswitch 234 is turned on is as follows. When the film in the camera unit is loaded into the processor unit, it is uncertain how much film loop there is in the film supply chamber 103 at the beginning of loading, so first, increase the film feed speed of the processor unit to a high speed and immediately. Reset the amount to zero. Next, switch to a low speed because if the film is fed at a high speed, the loop amount detection micro switch 234 will operate repeatedly in a short period of time, and the film will be repeatedly fed, resulting in a large amount of wasted blank space on the film. In order to prevent this, the time required until the micro switch 234 is activated is extended once the speed is changed to low speed. By the way, when loading film into a camera, it is generally done in a well-lit room, so the length of the film up to the leading edge is exposed to external light and fog occurs, and this fogged area does not cover the image. It is necessary to prevent exposure to light. Generally, a length of approximately 1.5 m from the leading edge of the film is defined as the fogged area, so in this embodiment, the fogged area is also defined as a 1.5 m long area from the leading edge of the film. In the above embodiment, the length of the film path from the film supply chamber 102 of the camera unit to the take-up reel 285 of the processor unit is approximately 1.5 m. Therefore, after setting the film and before starting photography, turn on the supply switch _S2 in order to feed the film in the foggy area without photographing it at the exposure section (feeding the film through the exposure section without photographing). do. Switch S ₂
When turned on, AND gate _G3 opens, motor drive memory 528 is set via set pulse generation circuit 527, and motor drive circuit 525 is set.
A motor M is driven via the . The motor M is driven to advance the film, and in response to this film advance, a pulse is generated from the film advance detection microswitch 175 of the camera unit.
This pulse is counted by a first counter 530. When the count content of the first counter 530 reaches "25" during this idle feeding, the switch consisting of the connectors 5 and 5' is in the on state, so the AND gate _G6 opens, and then the motor stop switch 15 is turned on.
7 is turned on, AND gate _G7 opens, motor drive memory 528 is reset, and motor M stops. Therefore, when used as a processor camera, the film in the camera unit is automatically fed 25 frames by turning on the supply switch. The first counter 530 is AND gate G ₇
It is reset by opening. When used as a processor camera, the leading edge of the film is manually attached to the take-up reel 285 of the processor unit in advance, so 150 frames of film are fed emptyly, and the feed switch _S2 automatically feeds the film. The amount is about 25
A small amount, about the size of a piece, is sufficient. On the other hand, when the supply switch _S2 is turned on when the camera is used as a normal camera without a processor function without connecting the processor unit, the motor M is driven in the same manner as described above. Since connectors 5 and 5' are in the off state, AND gate _G6 is always closed. When the count content of the first counter 530 is "150" during film feeding, the AND gate _G5 is opened, and the motor drive memory 528 is reset by turning on the motor stop micro switch 157, and the motor M is stopped. . Therefore, when using the camera as a normal camera, the film inside the camera unit is automatically removed.
The amount of blank feed is 150 frames, which is different from that of a processor camera. When the film in the camera unit is being fed, the feed indicator lamp 9 on the front of the support unit lights up (waveform F) to notify the user that the film is being fed.

Next, at time _t3 , the temperature of the developer decreases to a predetermined temperature (30~
32° C.), a signal indicating that the liquid temperature has reached a predetermined temperature is output from the thermo switch 240 (V waveform), and the liquid temperature detection memory 570 is set. As a result, AND gate G ₁₆ opens and photography is prohibited memory 57.
1 is set. By setting the shooting prohibition memory, the weight display lamp 565 goes out (G waveform), and the AND gate _G1 becomes open, canceling the shooting prohibition, and when the shutter switch _S8 is turned on, shooting can be performed. can.

Next, when the shutter switch _S8 is turned on at time _t4 (D waveform), the trigger pulse generation circuit 520 is activated via the AND gate _G1 , from which a trigger pulse is generated, and this signal activates the shutter timer. 521 is activated, the shutter solenoid 132 is turned on for the operating time of this timer (L waveform), and the subject is photographed on film. At the fall of the output signal of the shutter timer 521, the set pulse generation circuit 523 is turned on, and the motor drive memory 524 is set via the OR gate G30. Therefore, at the end of photography, the motor M is driven via the motor drive circuit 525 (J waveform) and the film is fed. When the film has been advanced by one frame, the motor drive memory 524 is reset by turning on the motor stop switch 157, and the motor M is stopped. Further, when the motor stop switch 157 is turned on, the counter imprinting and mark imprinting timers 535 and 536 are turned on. At this time, if the symbol imprinting switch S ₄ is turned on, the AND gates G ₈ and G ₉ are opened, and the counter imprinting lamp 539 and the mark imprinting lamp 540 are turned on via the lamp drive circuits 537 and 538. (M, P waveforms), frame numbers and marks are imprinted on the film. However, if the symbol imprinting switch _S4 is turned off, each lamp will not light up and the frame number and mark will not be imprinted on the film.

In addition, while motor M is driving, AND gate G ₁
is closed, so even if you turn on the shutter switch _S8 , no pictures will be taken.

Thereafter, the above operation is repeated every time the shutter switch _S8 is turned on to take a picture.

Pulses are generated from film advance detection microswitches 175 and 279 in response to film advance from the camera unit and processor unit.
This pulse is not counted by the second counter 560 because the AND gates G ₁₄ and G ₁₅ are closed until the photographing prohibition is canceled, that is, until the photographing prohibition memory 571 is set. After the photography prohibition memory 571 is set, the micro switch 17
When a pulse is generated from 5,279, the AND gate
G ₁₄ and G ₁₅ open, and this pulse is sent to the second counter 5.
Sent to 60. One micro switch 175
The pulses from the microswitch 279 are added and counted by the second counter 560, and the pulses from the other microswitch 279 are subtracted and counted by the second counter 560.

Now, when shooting many times in a fast cycle, the film in the processor unit is fed at a low speed at the beginning of shooting, so the camera unit feeds only the difference between the amount of film taken up by the processor unit and the amount of film fed to the camera unit. Winding chamber 10
The amount of film in the winding chamber 3 increases, and a large amount of film loops are formed in the winding chamber. Therefore, as the amount of film in the winding chamber increases, the count value of the second counter 560 increases, and when the count reaches "150" (time _t7 ), a signal is output from the decoder 561. The OR gate G ₃₄ opens and the feed rate switching solenoid 2 is connected via the solenoid drive circuit 563.
65 is turned on (U waveform) and the film in the processor unit is fed again at high speed. After this,
When the shooting operation is performed in a slow cycle, the winding chamber 103
The film loop inside decreases and the second counter 5
When the count of 60 becomes less than 150, the solenoid 265 is turned off and the film feed speed is switched to a low speed. However, if the shooting operation continues at a fast cycle after switching to high-speed feed, the film loop will further increase, and when the count content of the second counter 560 reaches "200" (time t ₈ ), the decoder 562 A signal comes out from
ORGATE G ₃₇ opens and weight display lamp 5
65 lights up. Photographing is prohibited while this lamp 565 is lit. After this, the second counter 560
When the count becomes smaller than "200" (time t ₉ ), the weight display lamp 565 goes out and photography can be performed again.

Thereafter, depending on the time interval at which the shutter switch _S1 is turned on (shooting interval), _t4 to _t7 , _t7 to _t8 , _t8 to
An action indicating one of the states of _t9 is performed.

Here, a case will be described in which the space switch _S7 is turned on during shooting. When the space switch _S7 is turned on while the photographing is possible and the motor M is stopped, the AND gate _G2 opens and the set pulse generation circuit 526 is activated, so the motor drive memory 524 is set and the motor M is driven. . When the motor M rotates a predetermined amount and the film is fed by one frame, the motor stop switch 15 is activated.
7 turns on, motor M stops. Therefore, the film has been skipped by one frame, and an unexposed blank area can be formed between the frames of the film. The spacing between these blank spaces is determined by the space switch.
It can be changed depending on the number of times the S ₇ is turned on.

Furthermore, if the shooting operation is interrupted midway through, the film in the processor unit is fed, so the amount of film in the winding chamber of the camera unit decreases, and when there are no more loops in the film, the loop detection switch 2 is activated.
34 is turned on, the motor M is driven in the same way as described above, the film is fed by one frame, and the film is supplied to the take-up chamber 103. Also, when the loop detection switch 234 is turned on, the second counter 56
0 is reset. Loop detection switch 234
The reason for resetting the second counter 560 with the signal is that when the film is advanced by one frame (10 mm) in the camera unit and processor unit, the switches 175, 279 to 1 of the camera and processor
pulses are generated in the winding chamber 103 of the camera.
a second counter 560 for measuring the amount of film in the
Since the counting result may differ from the actual amount of film due to errors in mechanical parts, etc., the counter should be reset when the loop detection switch 234 detects that there are no more film loops in the take-up chamber. This is to eliminate problems caused by errors.

The second counter 560 is operated until the photographing prohibition memory 571 is set, that is, after the developer reaches a predetermined developing temperature and the power is turned on.
Pulses are not counted until the loop detection switch 234 is turned on.

Next, the step selection switch _S3 and the reversal switch _S9 will be explained. Now, if step selection switch S ₃ and inversion switch S ₉ are left in the OFF state without being operated, exclusive OR gate G ₄₀ will close, and NAND gate
Since G ₄₁ is opened, AND gate G ₁₀ is opened, and the step display lamp 555 is lit via the lamp drive circuit 552, and the symbol imprinting counter 13 in FIG.
Displays that the contents of 4 will change. On the other hand, since the counter non-stepping solenoid 216 is off, the motor M and the counter drive shaft 208
The counter advances in conjunction with the drive of the motor M, and a different frame number can be imprinted on each frame.

Next, when step selection switch S ₃ is turned on, exclusive OR gate G ₄₀ opens and solenoid drive circuit 55
Counter non-stepping solenoid 216 through 7
is turned on, AND gate _G11 is opened, and the non-step display lamp 556 is lit via the lamp drive circuit 553, indicating that the contents of the symbol imprinting counter do not change. Solenoid 21
6 turns on, the counter release lever 213 shown in FIG. 3 rotates, the connection between the motor M and the counter drive shaft 208 is severed, and even if the motor M is driven, the counter does not advance. Therefore, even if images are taken one after another in this state and the contents of the counter are transferred to the film, the frame numbers of each frame on the film will be the same.

Next, if you turn off the advance selection switch S ₃ and turn on the reverse switch S ₉ while shooting with the counter advancing, the AND gate G ₁₃
opens, the content of the binary counter 550 becomes "1", a signal is output from its output, the exclusive AND gate G ₄₀ opens, and the NAND gate G ₄₁ activates the oscillator 55.
Opens intermittently at 1 pulse interval. As a result, the counter non-stepping solenoid 216 is turned on via the solenoid drive circuit 557, and even if the motor M is driven, the contents of the symbol imprinting counter do not change. Also, the AND gate G ₁₀ opens intermittently like the NAND gate G ₄₁ , and the step display lamp 555 blinks. When the film is fed after exposure and the motor stop micro switch 157 is turned on, the binary counter 550 is reset, the exclusive OR gate G ₄₀ is closed, and the original state of incrementing the contents of the symbol imprinting counter is restored. do. Therefore, when the step selection switch _S3 is turned off and the function of making the counter move in increments is selected, turning on the reversing switch _S9 temporarily changes the state from incrementing to not incrementing. be able to. In other words, the function of the step selection switch can be temporarily reversed by the inversion switch.

If you turn off the step selection switch _S8 and turn it on by pressing the reverse switch _S9 by mistake,
If you press the reverse switch _S9 again before taking a picture, the contents of the binary counter 550 will become "0", so you can return to the original state of incrementing the contents of the symbol imprinting counter without outputting a signal. .

Even if you turn on the reverse switch _S9 while shooting with the forward selection switch _S3 on,
As described above, by turning on the reversing switch _S9 , the function is temporarily reversed from a state in which the symbol imprinting counter is not incremented to a state in which the counter is incremented.

Finally, the case where the power switch is turned off after photographing is completed will be explained.

At time _t11 , when the power switch _S1 is turned off, a logic "1" signal is input to one input terminal of the AND gate _G20 , but the shutter trigger pulse generated by the first shooting operation is Since the shutter memory 597 has been reset by the shutter memory 597, the AND gate _G20 is in a closed state. Therefore, even if the power switch _S1 is turned off, the relay 593 remains on, and the power supply circuit 5
Power is supplied to the entire device by 96. on the other hand,
The third counter 59 is turned off by turning off the power switch _S1 .
0 is reset.

In the processor unit, the film continues to be fed, and as a result, when there are no more film loops in the film take-up chamber 103 of the camera unit 1, the loop detection switch 234 is turned on, and this signal opens the AND gate _G19 and the loop detection memory 581 is turned on.
is set. By setting the loop detection memory 581 and turning off the power switch _S1 , the AND gate _G18 is opened every time a pulse is generated from the film advance detection microswitch 279, and this pulse is counted by the third counter 590. Further, when the loop detection switch 234 is turned on, the motor M is driven as described above, and the film is skipped by one frame. When the above operation is repeated and the loop detection switch 234 is activated 150 times, the film is fed 150 times and the count content of the third counter 590 becomes "150", the OR gate G ₃₆ is opened by the signal from the decoder 591, and the relay 593 is turned off and all devices are de-energized. In other words,
After the final exposed area of the film reaches the take-up reel 285 of the processor unit, power is automatically cut off. Therefore, when you turn off the power switch after shooting, all the frames you photographed will be completely developed, fixed, washed, and dried, and then the power will be turned off automatically, making operation extremely easy and preventing mistakes. It can be prevented.

As described above, according to the present invention, the necessary amount of film is automatically fed automatically depending on whether or not the processor unit is attached, and the waste of film can be minimized. .
