Abstract

PURPOSE:To measure the extent of large movements accurately without any speed reducing mechanism of a large reduction ratio in a measuring device for extent of movements by repeating the operation of resetting a rotating disc which rotates in accordance with movements to an initial position at the point of the time when said disc makes required rotation. CONSTITUTION:The rate of feeding a film in a rotary processor camera which photographs the image of an original 1 while moving the original and a film F is transmitted as revolutions of a capstan roller 11 via gears 30, 32-34 to a cam gear 35. When the film is fed by the 1st prescribed rate, a switch 45 is actuated by a cam 35a, by which a solenoid 37 is operated to rotate a movable arm 31. Since the gear 34 is detached from the gear 35 by said arm, the gear 35 is returned to the initial position by means of a spring 40. Then the solenoid is disabled and the gear begins to rotate again. Further when the film is transferred by the 2nd required rate, the 2nd cam 35b actuates a switch 46, and the similar operations are accomplished.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an apparatus for measuring the amount of movement of a moving body such as a sheet material, in which a rotary plate is rotated in conjunction with the rotation of a roller, and a protrusion such as a cam is attached to a predetermined position of the rotary plate. The amount of sheet material transported is measured by detecting the protruding position of the kernels using a micro switch, and the movement of the sheet material is controlled according to the amount of sheet material transported.

In such a transfer device, one process is completed by, for example, transferring the sheet material by a predetermined first length k, and then transferring the sheet material 1 from this position by a second length. In this case, first and second protrusions are provided on the rotary plate in order in the direction of rotation of the rotary plate, and when the rotary plate rotates by a predetermined angle after the sheet material transfer starts, the first protrusion activates the i-micrometer. It is detected that the sheet material has been transferred a predetermined 10th length, and when the rotary plate is subsequently further rotated by a predetermined angle, the second protrusion operates a micro switch, so that the sheet material is transferred to a predetermined second length. By detecting the length of the sheet material being transferred and rotating the rotary plate in a fixed direction, the amount of sheet material transferred in one process is measured. With this method, if the amount of transfer to be measured during one process is large,
There is a problem in that either a speed reduction mechanism must be provided and the speed reduction ratio must be increased so that the amount of rotation of the rotary plate is smaller than the amount of rotation of the rollers, or the size of the rotary plate must be increased.

The present invention solves the above problems and accurately measures a large amount of movement in one process of a moving object using a small rotary plate without increasing the size of the rotary plate or providing a reduction mechanism with a large reduction ratio. The object of the present invention is to provide a movement measuring device for measuring the amount of movement.

When the clutch 26 operates, the driving force of the motor 22 increases (bell) 2-4. is transmitted to the drive shaft 25 via the roller 27,
The cab ``p'' and sx rotate, and the paper F is fed in synchronization with the original.

A gear 30 is fixed to the drive shaft 25 of the carburetor methane tube 11 for film transport, and this gear 3°0 meshes with a gear 32 attached to a movable arm 31. Furthermore, movable arm 3
1 is provided with linear intermediate gears 33 and 34, and the intermediate gear 33 meshes with the gears 32 and 3'4. Movable arm 31 is gear 3
According to the rotation of the movable arm 31, the intermediate gear 34 moves to a position where it engages with the cam gear 35 and a position where it does not engage with the cam gear 35. A tension spring 36 is attached to one end of the movable arm 31.
and the solenoid 37 are connected 1, and the movable arm 31 is rotated clockwise by the action of the shaft spring 36, and from this K the intermediate wheel 34 moves to a position where it meshes with the cam gear 35.
When the solenoid 37 is actuated, it rotates counterclockwise, thereby moving the intermediate gear 34 away from the cam gear 35 to the nine position. Since the cam gear 35 is used to measure the film feed rate of the film processed in one process, a first cam 35a for detecting the first rotation amount of the rotary plate and a 20th rotation amount are installed at predetermined positions on the surface. A second cam 35b for detection is provided. The cam gear 35 is biased to rotate counterclockwise by a return tension spring 40, and the cam gear 35 normally rotates counterclockwise.
It is located at the start position (initial position) where the protrusion 41 provided on the holder and the strut bar 42 of the fixing part engage.

When the solenoid 37 is inactive and the intermediate gear 34 and the cam gear 35 mesh with each other and the capstan roller 11 rotates to feed the film, the gears 30 and 3
The cam gear 35 rotates in the direction of the arrow through the gears 2, 33, and 34, and the cam gear 35 rotates by an amount corresponding to the feed amount of the film.
The solenoid 37 rotates while the cam gear 35 is rotating.
When actuated, the intermediate gear 34 moves away from the cam base 35, and the cam gear 35 returns to the start position by the action of the tension spring 40. During the rotation of the cam gear 35, the first switch 4 for detecting the film feeding amount is activated by the first cam 351L.

Furthermore, the movable arm 52 is rotated by operating the operating lever 62. The operating lever 62 pivots about a shaft 63 and is urged to rotate clockwise by the action of a tension spring 6.4. The upper tip 62JL of the operating lever 64 engages with the lower surface of the right end of the movable arm 52, and when the operating lever 62 is pushed downward against the force of the spring 64, the operating lever 62 moves counterclockwise around the shaft 63. The right end of the movable arm 52 is moved upward by the upper tip 62 & of the operating lever, and the movable arm 52 is rotated counterclockwise, resulting in a state IIK in which the gears 53 and 51 mesh with each other. When you release your hand from the operating lever 62, the operating lever 62 returns to its original position due to the action of the spring 640, but the left end of the movable arm 520 engages with the control arm 6S, which causes the movable arm 5! The gears 51 and S3 are held in a well-meshing position.

When the operation lever 62 is operated, the motor drive switch 70
is activated, and the motor 71 is driven by the signal output from this switch 70. The motor 71 is connected to the shaft 56 via a belt 72. Therefore, when the operating lever 62 is operated, the motor 771 is driven and the gear 51.・5
3 are engaged, and the driving force of the motor 71 causes the belt 72 to rotate, thereby sending the film in the storage chamber 13 to a part of the processor. Reference numeral 74 is an operating lever detection switch that outputs a high level signal when the movable arm 52 rotates to a position where the gears 51 and 53 are aligned with each other.

The movable arm s2 rotates in the hour hand direction due to the zero action, and the gear 53 moves to a position away from the gear 51. When the solenoid 77-II is activated, the capstan roller 15 stops, the film is no longer fed, and the cutter is activated to cut the film.

The motor 71 also serves as a driving source for driving a film feeding roller of a part of the processor.

Next, the operation of the above device will be explained.

First, before starting the photographing operation, open the cover (not shown) of the film loading section of the device, pull out the leading end of the film r from the supply reel 7 by hand, and transfer the film to the guide roller 8. Focus point 10, capstan roller. 1. IK hook, through storage room 13, cabstan ruler Xi and pinch low? Load the film with the leading edge of the film sandwiched between the two. At ζO, the power switch (not shown) of the device is turned off and the motors 22 and 71 are not driven.

The cam gear 34 and the cam gear 35 are in a meshed state, and the gear 51 and the gear 53 are in a non-meshed state.

Next, after loading is completed, when the operation lever 62 is operated, the movable arm 52 rotates so that the gears 51 and 53 do not mesh, and the motor 71 is driven by the output signal of the switch 70, which causes the capsmen to The roller 5 rotates and the film in the storage chamber 13 is sent out of the storage chamber. When the operation of the operating lever 62 is stopped, no signal is output from the switch 70, the shutters 5 and 71 are not driven, and the film stops. Stop operating the operating lever 62 and turn the gears 51 and 53.

Then, when the film has been transferred by the first predetermined amount after the start of transport of the film, the second cam 35bK and the second switch 46 are activated, and the output signal of this switch activates the solenoid 37, and the movable arm 31
rotates, the gear 34 moves away from the gear 35 to the nine position, and the action of the spring 40 causes the cam gear 3s to return to the starting position. When the cam gear 35 returns to the starting position, the solenoid 37 becomes inactive, and the action of the spring 36 causes the movable arm 3.
l rotates in the opposite direction, and the gears 34 and 35 are brought into mesh again. The film F is continuously fed out from the storage chamber by the capstan roller 15 and the pinch roller 16.
The cam gear 35 rotates again in the direction of the arrow, and when the film is further transferred by a second predetermined amount, the first cam 351L operates the first switches 4 and 5, and the signal output from the switch 45 causes the solenoid to be activated. 37/77 works.

The actuation of the solenoid 37 causes the cam gear 35 to return to the starting position again. On the other hand, the movable cutter 76 moves due to the operation of the solenoid 77, the film is cut by the cutters 75-76, and the control arm 65 and the movable arm 52 are disengaged due to the operation of the solenoid 77, and the gear 53 moves to the gear 51. The capstan roller 15 is moved away from K to the 9 position, and the capstan roller 15 is stopped, and the film is no longer fed out from the storage chamber 13. (By the above operation), move the operating lever (min.)
The film is fed by the length until it passes the cutting position of the force turf 5/76. 9. Load the film into the bale, turn on the power switch, and the capri part at the leading edge of the film is automatically fed, and the image of the original is printed on this fogged part. Ejected to some trays.

When the cam gear 35 returns to the starting position, the solenoid 37 is deactivated and the gear 34 and cam gear 35 are brought into alignment again.

In addition, when the cam gear 3s rotates in the direction opposite to the arrow direction, each cam 35a.

35b, the switches 45 and 46 are activated, but their output signals are disabled.

Next, move the document 1 between the capstan roller 2 and the pinch roller 3.
When the document is fed between 0 and 0, the source document is fed between the pair of glass plates 40 by the rollers 2 and 3.

When the original 1 passes between the glass plates 40, it is illuminated by a lamp (not shown). On the other hand, when the document is fed between the document 1 incubation rollers 2 and 3, a document detector (described later) detects the document.
The stain magnetic latch 26 and the shutter solenoid 80 are actuated by this signal.

The drive shaft 25 and the four-wheeler 27 are connected by the operation of the electromagnetic clutch 26.
The shutter 81 is operated for a fixed period of time, and the reflected light image of the original is transferred to the lens 9.
Since the cabstan roller 15 is stopped, the exposed film F is stored in a loop in the storage chamber 13. The cam gear 35 rotates in accordance with the rotation of the cabstan roller 11. 7 manuscripts
Each time an image is taken, the film is sent to the storage chamber, and the amount of film stored in the storage chamber 13 increases. When the second cam 35b operates the second switch 46, the upper limit of the film storage chamber in the storage chamber is reached, and an alarm such as a buzzer is activated.
A cloud that clearly indicates the prohibition of photography. When the alarm is activated, or before the alarm is activated, will be described later. When the development command switch is operated, the solenoid 37 is activated, and the cam gear 3
5 is returned to the starting position, and then when the turlenoid fails 11K, the gears 34 and 35 mesh again. i9! By operating the I-image command switch, the solenoid 60 is activated, the movable arm 52 rotates, and the gear 51-! ! 3 is engaged i1 middle yapsmen roller 15. rotates, and the exposure source film in the storage chamber 13 is delivered to a part of the processor. After this, when the film in the storage chamber decreases and the film loop in the storage chamber disappears, that is, the film in the storage chamber reaches the lower limit, the film is pulled out from the exposure position by the capstan row 215. capstan roller 11'#
The cam gear 35 rotates as the cam gear 35 rotates due to the driven rotation.

When the first force 35a operates the first switch 45 due to the rotation of the cam gear 350, the solenoids 37 and 77 are actuated by the signal output from the switch 45, and the cam gear 35 is activated.
is returned to the starting position and the film is cut by cutters 75 and 76. Set the position of the first cam so that when the first switch (5) is activated, the film is fed until the rear end of the exposure area of the fill table exceeds the cutting position. The control arm 65 and movable arm 52 are disengaged, the gear 53 moves to a position away from the gear 51 7, and the capstan four-wheeler 15 stops.

Therefore, when the development command switch is operated, only the exposed film portion is separated from the unexposed film and sent to a portion of the processor. The alarm goes off when the cutter is activated.

(activated), the photography prohibition is lifted, and the original is placed in the loaf F again.
If you feed the camera between 2 and 3, you can resume the shooting operation.

As described above, after the shooting starts, the first switch 45 measures the first transfer amount of the film, and the second switch 46 measures the second transfer tray of the film.
- The amount of 7 film transferred during the two steps from the start of the shadow until the film is cut is accurately measured using a small cam gear.

On the other hand, the cam gear solenoid 37 is operated to return the cam gear 35 to the starting position. Operating time for monomulti circuit1. is a mono multi-circuit 11i! , 0 operating time t, is set very short. Therefore, time 1. The AND gate opens for the time difference between and t, and the signal output from the AND gate connects the shift latch 26 for a short time (1111), causing the capstan roller 11 to rotate and feed the film a short distance. The slack in the film between the capstan roller 11 and the supply reel 7 is removed, and the film F is brought into close contact with the circumferential surface of the focusing roller IO. Therefore, after cutting the film, the capstan roller 11 and the supply reel 7
0, the film will loosen due to vibrations caused by the cutter, etc., but the above structure eliminates the slack in the film base.
The film will not shift from the imaging position of the lens 9.

As described above, even if the document 10 is sent to the rollers 2 and 3 while the capri part of the film is being fed to the processor part, the shutter solenoid 80 will not operate because the AI is closed and the shutter solenoid 80 is not activated. , the original is not captured on film.

After cutting the film, the spy lever detection switch 7.4 is deactivated, and when the document detector 100' detects the document, the AND gate A opens, and the solenoid 80 and clutch 26 are activated.
