Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a camera that records subject information and other information on a film.

Conventionally, cameras have a counter that is linked to the operation of a shooting switch to record the frame number on the side of each subject photographed on film, and the counter is incremented each time a photograph is taken to record the contents of the counter. However, according to this method, only frame numbers are recorded on the film in a predetermined order, and special equipment must be installed to record search code information other than frame numbers. The disadvantage is that it is complicated.

The present invention aims to eliminate the above-mentioned drawbacks and provides a camera with a simple structure that can imprint various code information onto the film.

The present invention will be explained below using specific examples shown in the drawings.

Fig. 1 shows the entire camera of the present invention, and in the figure, each unit that can be attached to and detached from the main body base is shown removed, but each unit is configured to be detachable from the main body base. It is supported by a stand and exerts its function by being attached to the main body base. 1 is a camera unit;
This unit is a raw (unexposed) film supply section,
It has an exposure section, a film drive section, a film winding section, a photographic lens, etc., and the details 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. A camera unit 1 and a processor unit 2 are configured to be detachably attached to a support unit 3, and are connected to a connector 4,
4', 5, 5' electrically and mechanically coupled.

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. Step selection switch, _S4 is a signal imprinting switch that selects whether or not to capture the search mark and the contents of _the counter mentioned above on the film. This is an exposure magnification switch that changes the exposure time to several times the initial setting time. Reference numeral 14 denotes a light receiving section that measures the illumination light illuminating the subject, and controls the opening time of the shutter. Reference numeral 15 denotes a light source unit for illuminating 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 the space switch to advance the film one frame, _S8 is the shutter switch, and _S9 is the switch that selects whether or not to advance _the counter automatically. This is a switch that temporarily reverses the state of the counter so that it is reversed (only when pressed) and returns to the setting state of switch _S3 after the shutter is pressed. In this camera, the camera unit 1 and the processor unit 2 are removable from the support unit 3, and when only the camera unit 1 is attached to the support unit 3 connected to the main body base 6, the camera unit 1 and the processor unit 2 are attached to the support unit 3. It is configured so that it can be used as a film camera. 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, depending on the shooting magnification of each camera unit, the frame 2 of the sheet 20 indicating the shooting range
It is necessary to change the position of sheet 1, so sheet 2
0 is replaceable, and you can use the one that suits your camera unit.

Next, details of the camera unit will be explained with reference to FIGS. 2 to 7.

In FIG. 2, reference numeral 101 denotes the upper body of the camera unit 1, and a front chamber is divided into a back chamber by a partition 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. Further, the front chamber is divided by a central wall into a film supply chamber 102 on the right side and a film winding chamber 103 on the left side. There are 104. A film winding chamber 103 is located at the upper outside of the film supply chamber 102.
and a film passage 10 connecting the processor unit 2 and the processor unit 2.

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 mounted on the upper body 101 so as to be rotatable 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. The lever 109 in the supply chamber is connected to the reel 1
This is for detecting the remaining amount of film wound on the upper body 101, and at one end there is a shaft 11 which is rotatable with respect to the upper body 101 and biased by a spring in the counterclockwise direction.
0, and the other end is provided with a roller 111 that rotates in contact with the outer peripheral surface of the film wound on the reel 108. 112 is a guide roller for the film F. 113' is a capstan roller, and 113 is a pinch roller, which is rotatable on a shaft 115 on a lever 114 having a shaft 116 that fits into a hole in the body 101 and is elastically biased clockwise. The film F 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 natural to use the film winding shaft as shown by the dashed double dotted line in the center of the film winding chamber.
7' (a reel is attached to this film take-up shaft), but if the camera unit is connected to a processor unit and used as a camera with a processor, it can be disconnected from the coupling hole 118 and the film can be taken up. It is evacuated to a corner 117 of the room. When used as a camera processor, this film winding chamber is used as a film loop chamber (buffer chamber). Of course, the attachment and detachment of the winding shaft 117 to and from the coupling hole 118 are as follows.
Consideration has been given to making it easy for the user. A film guide roller 119 guides the film in the take-up chamber 103 to the processor unit via the film passage 105 and the connecting pipe 106.

A lower body 120 is attached to the lower side of the upper body 101, 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 protrudes from one end of a lever 125 for pressing the film against the plate during exposure and holding the film in a predetermined position and flat. The pin 126 is loosely attached to the pin 126. A shaft 127 is fixed to the other end of the lever 125, and the shaft 127 fits into a hole provided in a bulkhead of the aircraft body and is biased to rotate clockwise by a spring provided in the back chamber. ing. As shown in FIG. 4, the aperture plate 123 has an aperture 123a for determining the photographing range of the subject, a window 123b for imprinting a mark, and a window 123c for imprinting a frame number. In FIG. 2, 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 arranged between the aperture 123a and the photographing lens 129, and blocks light from the photographing lens 129 toward the film F through the aperture 123a except when photographing. The shutter blade 130 is the lower fuselage 120
When exposing the film, the shutter solenoid 132 is attracted by a signal from the control unit 11 on the base of the main body, and the effective optical path of the photographic lens 129 is adjusted. Run outside. 133 is a return spring for 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, but also can be read adjacent to the image on the film using the same number displayed on the reading window as a frame number 142 if necessary. (5th)
(see figure). 137 is a number imprint ring made of translucent resin material for this purpose, and 6
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. Reference numeral 138 denotes a lamp that illuminates the ring 137 from the inside to imprint characters on the film, and is blinked in response to a signal from the control section 11. 145 is a light-shielding plate with a window that allows only the light from the numbers at a predetermined position to pass among the letters on the ring 137 illuminated by the lamp 138, and prevents unnecessary leakage light from reaching the film. . The light passing through the window of the light shielding plate 145 passes through an optical system including a first mirror 146, a second mirror 147, an imaging lens 148, etc., and passes through the window 123c of the aperture plate 123 to the film F.
Photographed above, frame number 1 between the pieces.
It is imprinted as 42. , 135 is a drive wheel that drives the reading character wheel 136 and the number imprinting ring 137, and is in mesh with a ratchet wheel divided into 10 circumferences and gears provided on the reading character wheel 136 and the number imprinting ring 137. It is made up of certain gears. There is no need to explain this, but the number of teeth on the husband's gears are all the same. A part of the circumference of the gear of the reading character wheel 136 is located on the bottom cover 13.
9 protrudes into the recess 141 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. Therefore, code information other than the frame number can be recorded on the film by setting the counter number arbitrarily. For example, group numbers, dates, photographic data, etc. that are unrelated to the number of times of photographing can be recorded. Note that an optical system for imprinting the contents of the counter onto the film is provided in front or behind the exposure section. By imprinting the contents of the counter onto the film using an optical system separate from the optical system for photographing the subject, the size of the image of the counter on the film remains constant regardless of the photographing magnification of the subject, and the size of the counter image changes depending on the photographing magnification. There is no need to change the arrangement position, there is no need to place the counter at an optically equal distance from the object surface, and the arrangement position is not restricted, which is extremely advantageous in terms of manufacturing.

148 is a connector that relays electrical signals from the control section 11 to the camera unit;
It is fixed to the lower body 120 via 49.

FIG. 3 shows the back chamber 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, 151 to 154 are gear trains for decelerating and transmitting the rotation of the drive motor M, and the final stage gear 154 A driving pin 155 and an operating cam 156 of the pressure bonding plate 124 shown in FIG. 2 are integrally formed on the holder. Numeral 157 is a micro switch which is operated by a pin 155 to switch every time the gear 154 rotates once, and sends a signal to the control unit to control the gear 154 to stop after one rotation. When the gear 154 rotates once, the drive pin 155
The connecting frame 158, which has one end attached to the shaft, rotates the gear 167 on the right side by 60 degrees clockwise, as will be described in detail later, and meshes with the gear 167 to rotate the capstan 113' (FIG. 2) fixed to the shaft 169 of the gear 168. The film F is fed by one pitch (P in FIG. 5) through the film. Further, the gear 168 drives a gear 173 and a cam wheel 174 integrally formed therewith via a gear train 170-172. The cam wheel 174 activates the film advance detection micro switch 17 by its rotation.
5 is intermittent, but the frequency of intermittent film feeding is 10
It is designed to be interrupted once per mm. That is, in this embodiment, the diameter of the capstan 112 is 19.1 mm, and one rotation of the cam gear feeds the film 60 mm. On the other hand, micro switch 17
There are eight protrusions on the outer periphery of the cam ring 174 that press the actuator No. 5, and one rotation of the cam ring 174 causes the micro switch 175 to be turned on and off eight times. Therefore, by the gear train 170-172, the gear 1
The rotation ratio between gear 68 and gear 173 is 8:6.

FIGS. 6 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.
Pin 155, micro switch 157 (Figure 3)
Due to the synergistic action of these, it stops after making one revolution.
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 implanted at the other end of the swing arm 159, and serves as a fulcrum shaft for the ratchet pawl 160. The tip of the ratchet pawl 160 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 attached to the upper body 1.
The ratchet wheel 1 is fitted onto a fixed shaft 166 protruding from the
The ratchet wheel 162 is pressed against the outer periphery of the ratchet wheel 162, and prevents the ratchet wheel 162 from rotating in reverse. A pin 158' on the swing arm 159 and a pin 155 on the gear 154 are respectively fitted into holes at both ends of a rigid connection frame 158. With the above configuration, when the gear 154 rotates once as described above, the swinging arm 157 reciprocates once within the range of arrow a (approximately 65 degrees), and the ratchet wheel 162 moves at an angle corresponding to one tooth (approximately 65 degrees). It will rotate by 60 degrees. More specifically, during the first half-turn (lower half) of the pin 155, the pin 158' moves to the right, but the ratchet wheel 162 and the ratchet pawl 160 slide against each other, so the ratchet wheel 162 stops. It is still. pin 15
5, the pin 158' moves to the left within the range of arrow a, but at this time the tip of the ratchet pawl 160 touches the ratchet wheel 162.
toothing to rotate the ratchet wheel 162 clockwise. This rotation is caused by the gear 16 integrally connected to the shaft 163 of the ratchet wheel.
The film F pressed against the capstan roller 113' provided on the shaft 169 of this gear is fed by a certain amount.

In the field of photographing the 16 mm film used in this embodiment, there are various film advance amounts for each photograph, but 10 mm and 11.75 mm advance are common. Therefore, in this embodiment, the above-described structure is adopted in order to easily meet the requirements for both feed amounts. That is, the outer diameter of the capstan roller is 19.1 mm, the number of teeth of the ratchet wheel is 6, and the tooth ratio of gears 167 and 168 is set to 10.
1:1 (=50:50) for mm toothing, feed amount 11.75mm
In this case, the above objective can be achieved by selecting 1:11.75 (=46:54). Returning to Figure 3, 176 is the pinch roller 113 (Figure 2)
A pressing lever urges the shaft 116 counterclockwise (clockwise in FIG. 2) by a pin 177 implanted at one end of the lever, a lever 178 engaged with the pin, and a tension spring 179. are doing. Reference numeral 180 denotes a pressing lever of the pressure bonding plate 124 (FIG. 2), which is operated by a pin 181 implanted at one end of the lever, a lever 182 engaged with the pin, and a tension spring 183 to press the shaft 12.
7 in a counterclockwise direction (clockwise in FIG. 1).

Reference numeral 184 denotes a pressure release lever that swings about a shaft 185 protruding from the body 101 as a fulcrum shaft, and has a roller 186 at one end that contacts the outer peripheral surface of the cam 156. This lever 184 is approximately 1/2 of the gear 154.
During the period corresponding to the rotation, the large outer diameter portion of the cam 156 rotates counterclockwise via the roller 186, and the other end lifts the end 180a of the lever 180, resisting the spring 183, and rotates the shaft 127. turn clockwise,
The pressure of the film on the aperture plate 123 of the pressure bonding plate 124 is released. This operation is performed only when the film F is being fed, and when the film is stationary, the film is always pressed against the aperture plate 123 by the pressure bonding plate 124. 187 is a lever supported by a shaft 188 protruding from the fuselage 101;
Pins 18 that slide into the long holes of 8 and 182, respectively.
7a and 187b are planted. The lever 18
7 is biased counterclockwise by a torsion spring 189 about a shaft 188 as a fulcrum, but is restrained in the position shown in FIG. 3 when the opening/closing cover (not shown) of the front film chamber 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, and as a result, the levers 176 and 180 are moved clockwise to release the pinch. Roller 113, pressure bonding plate 124
is retreated from the orbit of the film F, making it easier to load the film.

Reference numeral 190 denotes a film remaining amount warning cam, which is fixed to the shaft 110 of the remaining amount detection lever 109 (FIG. 2). 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 beyond 1. Remaining amount cam 1
90, the fan-shaped member 193 has pins 191 and 19, respectively.
5 is implanted, and a connecting rod 196 having a hole in which the pin is rotatably fitted is suspended at both ends. A pin 196 is located approximately in the center of the connecting rod 196.
a is planted and the tension spring 19 is hung on the pin.
8 to the right, and as a result, the remaining amount cam 1
90 and the fan-shaped member 193 receive a clockwise rotational force. Rotating shaft 110 fixed to remaining amount cam 110
At the other end, there is a remaining amount detection lever 10 shown in FIG.
9 is fixed, and the roller 1 is attached to one end of it.
11 contacts the film F on the reel 108, the positions of the remaining amount cam 190 and the fan-shaped member 193 in the rotational direction are determined. That is, depending on the winding diameter of the film on the reel 108, the remaining amount cam 190 and the fan-shaped member 19
The rotation amount of 3 will be determined. 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 to sound the buzzer 202 to emit an alarm sound, indicating that there is not enough film left in the film supply chamber 102. Let me know when you're summer.

A lever 199 is pivotally supported by a shaft 203 protruding from the body 101, and a pin 199a that fits into a hole at one end of the lever 197 is implanted in a part of the lever. 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, the third lever 199 It 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 and the torsion spring 204 is released.
As a result, lever 1 is moved counterclockwise by
97 is pulled to the left, and the pin 196a comes into contact with the right end of the elongated hole 197a, causing the connecting rod 196 to also be moved to the left. Therefore, since the rotating shaft 110 rotates counterclockwise, the remaining amount detection lever 109 moves outward from the outer periphery of the reel 108. Therefore, the reel can be easily attached to and detached from the film supply shaft 107. 206 is a coil spring, and hooks at both ends thereof are fixed pins 20 that protrude from the body 101.
7, and its central portion is rotated 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, thereby preventing the film from sagging.

Reference numeral 208 is the drive shaft of the counter 134 shown in FIG. 2, and when it is rotated about 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
rotates 36 degrees (1/10 rotation), and the number advances by one. 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 letter ring for the second last digit, and after 100 times, the letter ring for the third last digit, etc., will each move 36 degrees. Since these mechanisms are conventionally known, their explanations will be omitted.

209, 210, and 211 are members for applying power to the counter as described above; 209 is a counter drive lever integrally connected to the drive shaft 208; 210 is a pin protruding from a push rod 211; It is rotatably fitted into a hole provided at one end of the. 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 section 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 20
9 drives the counter drive shaft 208 clockwise, and the counter 134 advances 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 moved by a return spring (not shown). ), it returns to its initial state and prepares for subsequent re-operation. 213 is a counter release lever, which is used to advance the film without advancing the counter. That is, the lever 213
is 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.

If it becomes necessary to feed the film F without advancing the counter, the solenoid 216 is energized at the same time as the motor M is normally energized. By energizing the solenoid 216, the plunger is attracted, and the counter release lever 213 rotates to the position shown by the two-dot chain line. Due to this rotational action, the right end portion 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 moving to , the pin and the shoulder portion of the push rod 211 do not engage with each other. Therefore, the motor M can feed the film without stepping the counter 134.
