Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reader printer such as a microfilm reader printer for enlarging and projecting an image on a microfilm onto a screen to obtain a copy print as required.

[0002]

[Prior Art]

(First Conventional Example) There are two types of images on a microfilm, one of which is vertically long and the other of which is horizontally long depending on the direction of characters and patterns. For this reason, for example, in an electrophotographic reader printer that obtains a copy image by vertically feeding A4 paper, when a microfilm image in which characters are written horizontally is copied to A4 paper, the image is horizontally displayed on the screen in the reader state. There is a problem in that when the image is projected onto the substrate and the print is taken, the carrier must be rotated in advance to correct the image in the vertical direction before the print is taken.

In order to solve this problem, a configuration is known in which a prism is arranged in the print optical path and the prism is automatically rotated by 45 degrees, that is, the image is rotated by 90 degrees when printing when the film image is horizontally long.

However, in the past, this prism rotation was performed by providing an independent dedicated drive means such as a stepping motor, and the control was complicated, and the cost was too high, so this configuration was not widely used.

Therefore, a prism body that changes the direction of the image light, an exposure unit that switches the image light that has passed through the prism body to either the reader optical path or the printer optical path by moving the position, and the exposure unit. Is known, which is provided with interlocking means for rotating the prism body around the optical axis of the image light in accordance with the movement of the. (Second Conventional Example) Generally, a microfilm reader printer needs a flat and bright illuminating device because of the characteristics of the photoconductor because the light emitted from the illuminating device to the microfilm is printed on the paper through the photoconductor. Become.

Further, in recent years, digitalization has progressed even in microfilm reader printers, and an image is confirmed using a light receiving sensor such as a photoelectric conversion element and various image processing is performed. For example, automatic exposure adjustment (AF), automatic black frame erasing, edge enhancement, or the like is performed. In these modes, erroneous detection and erroneous operation are lost, and further uniformity of image illumination light is required.

In addition, since the microfilm reader printer images the image irradiation light in a magnified image by the projection lens, unless the illumination light flux of the illuminating device and the imaging light flux of the projection lens are aligned with high accuracy, good image light is obtained. Can't get

As described above, in a microfilm reader printer or the like, a highly accurate illumination device is required in order to obtain a flat and large amount of image light.

However, in a lighting device with a large amount of light, the life of the light source is shorter than that of the main body of the device, so that the light source must be replaced by the operator.

Therefore, a reader printer having an illuminating device in which all the optical element parts for illuminating an object including a light source are made into one unit and the unit can be attached to and detached from a predetermined position of the apparatus body has been considered. ..

One example thereof is shown in FIG. Light source lamp 11
01, first and second condenser lenses 1102 and 1103, heat insulating filter 1104, first and second reflecting mirrors 1105 and 110
6 is held by an illumination base 1107 having a handle,
The illumination base 1107 is guided and held at a predetermined position of the reader / printer main body by a guide rail and a lock means (not shown) which are not shown.

However, as shown by the chain double-dashed line in FIG.
When pulling out the illumination base 1107 to replace the light source, the operability was poor because the space required for pulling out was large over the range A '.

Further, the light source lamp 1101 is a condenser lens 11
Since the light source lamp 1101 is sandwiched between No. 02 and the reflected light 1105, the replacement work (B 'direction) of the light source lamp 1101 is complicated.

Therefore, like the illumination unit shown in FIG.
The first and second condenser lenses 1102 and 1103, the heat insulating filter 1104 and the second reflecting mirror 1106 are held in the reader printer body, and the light source lamp 1101 and the first reflecting mirror 110 are held.
It is known that an improvement is made by fixing 5 to a detachable handle 1108.

[0015]

[Problems to be Solved by the Invention]

(First Problem) However, in the first conventional example, since the prism body could not be manually rotated, the image tilt on the screen could not be finely adjusted.

In order to make the distinction clear, the automatic rotation of the image by 90 degrees is called "automatic rotation", and the manual rotation of the image is called "manual rotation". (Second Problem) Further, in the second conventional example, the handle 1
Since the means for guiding and holding 108 at a predetermined position of the reader / printer main body must be shortened, the accuracy of the mounting position with respect to the reader / printer main body deteriorates. In addition, since it is difficult to hold the handle 1108 firmly, the light source lamp 1 is generated by the external force transmitted from the handle 1108.
The position of 101 with respect to the reader / printer body changed, and the illumination light amount distribution fluctuated.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a reader printer capable of obtaining a highly accurate reader state and printer state.

Therefore, a first object of the present invention is to allow the prism body to be manually rotated in addition to the rotation of the prism body by the interlocking means.

Therefore, a second object of the present invention is to mount a detachable light source that needs to be replaced by an operator with high positional accuracy and to be less susceptible to external influences.

[0020]

In order to achieve the above object, according to the present invention, any one of a prism body for changing the direction of image light and an image light passing through the prism body is used as a reader optical path or a printer optical path. In addition, an exposure unit that is switched by moving the position, an interlocking unit that rotates the prism body around the optical axis of the image light as the exposure unit moves, and an interlocking unit that rotates the prism unit. And a holding means for holding the prism body at a predetermined rotation position, wherein the prism body is provided at a position where the image light passes, and the light holding means for holding the prism is provided. A first rotation holder rotatable about an axis; and a first rotation holder which holds the first rotation holder and is rotated by the interlocking means coaxially with the first rotation holder with respect to the first rotation holder. Second rotation holder Only the first pivot holder by holding the rotational position becomes rotatable in said holding means,
Further, when the second rotation holder is rotated by the interlocking device, the first rotation holder and the second rotation holder are arranged to rotate the first rotation holder integrally with the second rotation holder. Engaging means for engaging with the rotation holder.

Further, in the reader printer including a light source holding unit detachable from the reader printer main body, the light source holding unit is a unit that is locked to the reader printer main body by a locking portion when mounted on the reader printer main body. A main body and a light source section that is swingably held in the unit main body within a predetermined range,
When the light source holding unit is attached to the reader / printer main body, a locking means for locking the light source unit to the reader / printer main body independently of the locking of the unit main body to the reader / printer main body is provided. Characterize.

Further, it is preferable that the locking means has a biasing means for applying a preload to the light source section toward the reader / printer body when the light source section is locked to the reader / printer body.

[0023]

According to the present invention having the above-mentioned structure, the second rotation holder of the prism body is rotated by the interlocking means as the exposure section moves. At this time, the first rotating holder is rotated together with the second rotating holder by the engaging means, and the automatic rotation is performed.

Further, when the first rotating holder is manually rotated while the second rotating holder of the prism body is held at the predetermined rotating position by the holding means, the first rotating holder is operated. The torque is transmitted from the to the second rotating holder through the engaging means, but since the second rotating holder is held by the holding means, the rotating position is not changed, and accordingly the manual rotation is performed.

When the light source holding unit is attached to the reader printer body, the unit body of the light source holding unit is locked to the reader printer body by the locking portion. Then, at this time, the light source portion movably held in the light source holding unit within a predetermined range is locked to the reader printer main body by the locking means independently of the locking of the unit main body to the reader printer main body. .. Then, when the unit main body is pulled out from the reader printer main body to remove the light source holding unit from the reader printer main body, the light source unit is held by the unit main body by the locking means, so that the light source unit is held in the unit main body. Is removed from the reader printer body.

If the locking means has a biasing means, the positioning of the light source holding unit with respect to the reader / printer body becomes more accurate.

【Example】

(First Embodiment) A schematic structure of a microfilm reader printer as a reader printer according to a first embodiment of the present invention will be described below with reference to FIG.

FIG. 2 (a) shows the overall schematic structure of the same reader printer. F is a microfilm, 1 is a projection lens, 2 is a prism, 3.4 is a reader mirror that forms a reader optical path, and 6.7 is a printer. It is a print mirror that forms an optical path. The print mirrors 6 and 7 are housed in a scan case 8 as an exposure unit so that they are formed at right angles to each other.

At the time of the reader, the scan case 8 stands still at the dotted line position B behind the reader mirror 4, and the image light of the microfilm passes through the projection lens 1 and is projected on the screen 5 via the reader mirrors 3 and 4. It

On the other hand, at the time of printing, the scan case 8 first moves (forward movement) in the direction of the arrow a (by the driving means (not shown)) and reaches the exposure start position A shown by the one-dot chain line (clutch means not shown). The image light of the microfilm is scanned and exposed on the photosensitive drum 9 via the mirrors 6 and 7 while reversing from that position in the b direction (backward movement).

Around the photosensitive drum 9, well-known image forming means such as a charging device, a developing device and a transfer device (not shown) are arranged.
A copy is made on the copy paper P by the electrophotographic method. 10
Is a paper ejection tray. A one-dimensional image sensor (CCD or the like) may be arranged in the exposure section, and a copy image may be obtained by the output of the image sensor and the laser beam printer.

The image rotating means uses the forward movement a of the scan case 8 at the time of the printer, and rotates the prism by the urging force of the spring.

FIG. 2B shows the structure of the main part of this embodiment.
The prism 2 has two arm portions 11a and 11b,
It is provided in a prism holder 11 that can rotate in the direction of arrow C. Here, the prism 2 and the prism holder 11 form a prism body 16. In the arm part 11b,
A biasing rotational force is applied in the d direction by the tension spring 12. The other arm 11a is locked by the lever 13a of the solenoid 13 in the leader state. That is, the prism holder 11 is positioned in the rotation direction. Here, solenoid 13, tension spring 1
2. The arms 11a and 11b form a holding means 18. In addition, the bent portion 1 at one end of another lever 14 is provided on the arm portion 11a.
4a is in contact. The bent portion 14b at the other end of the lever 14 is located so as to come into contact with and separate from the protruding portion 8a of the scan case 8. Here, the protruding portion 8a, the lever 14,
The arms 11a and 11b and the tension spring 12 are interlocking means 17
Make up.

Next, an outline of the operation of the reader printer will be described.

First, a horizontally long image is copied (prism 2).
If the print button (not shown) is pressed, the solenoid 13 is turned on and the locking of the arm portion 11a by the solenoid lever 13a is released. Next, the movement of the scan case 8a (in the direction of the arrow a) starts, but along with this, since the locking of the arm portion 11a of the prism holder 11 is released, the bent portion 14 of the lever 14 is also released.
The rotation is started by the pulling force of the tension spring 12 in the d direction while being regulated by a. The prism holder 11 rotates until the arm portion 11a hits the positioning portion 15,
Stop when you hit it. The positioning part 15 is positioned and provided so that the holder 11 can rotate by 45 degrees (the image is 90 degrees).

After the prism holder 11 is stopped, the lever 14 and the projecting portion 8a of the scan case 8 are separated from each other, and the movement of only the scan case 8 is continued in the a direction. Further, when the scan case 8 reaches the image exposure start position, the image light of the microfilm is transferred from the position to the photosensitive drum 9 via the print mirrors 6 and 7 while being reversely moved in the direction of the arrow b by the clutch means (not shown). Scan and expose on top.

Even after the scanning exposure is completed, the scan case 8
It continues to move in the direction of the arrow b as it is, and the protruding portion 8a again contacts the bent portion 14b at the other end of the lever 14. As a result, the prism holder 11 is provided with a rotational force that is opposite to the tensile force of the tension spring 12 and is returned to the position before the prism is started.
a is locked again by the solenoid lever 13a, and the prism holder 11 stops.

If the print button is pressed again and the scan case 8 is moved in the direction of arrow a before the scan case 8 starts moving in the direction of arrow a, the solenoid 13 attracts the solenoid lever 13a. This is effective because the load received from the arm portion 11a can be reduced.

Next, when a vertically long image is to be copied, the prism 2 does not need to be rotated. Therefore, even if the print button is pressed, the solenoid 13 is kept off and only the scan case 8 is moved. Is copied.

FIG. 1 shows the details of the structure of the prism holder 11 which is a characteristic part of the present invention. Reference numeral 20 denotes a first rotary holder for holding the prism 2 and a bearing portion 21 a of the second rotary holder 21 for rotating the prism holder 11. It is possible to move. The prism 2 is securely fixed to the first rotation holder 20 by the fixing member 23 and the screw 27. The fixing member 23 also has a masking function of blocking excess leaked light emitted from the prism 2.

The second rotation holder 21 can be rotated by the arms 11a and 11b as described above, and performs the rotation / return operation during the automatic rotation.

Reference numeral 22 denotes an operating ring, which is integrated with the first rotary holder 20 by the action of the hook portion 22a and is rotatable with respect to the second rotary holder 21. The operator finely adjusts the inclination of the image on the screen 5 by manually rotating the operation ring 22.

Reference numeral 26 is a restricting ring for restricting the vertical movement of the second rotating holder 21, which is fixed to the second rotating holder 21 by press fitting, bonding or the like.

Reference numeral 24 is a viscous material enclosed in the gap 19 between the first rotary holder 20 and the second rotary holder 21, and has a resistance to the rotation of the first rotary holder 20 with respect to the second rotary holder 21. give. Here, the holders 20 and 2 forming the gap 19
The wall surface of No. 1 and the viscous material 24 constitute the engaging means 28. Specific examples of the material include highly viscous grease and the like.

Next, the operation and action of these characteristic parts of the present invention will be described.

During automatic rotation, the second rotation holder 21 rotates and returns as described above, but the viscous material 24
By the action of, the first rotation holder 20 and the prism 2 also operate integrally. As a result, the second rotation holder 21 is simply
The same effect as that of the conventional example in which the prism 2 is directly fixed is obtained.

On the other hand, during the manual rotation, the operating ring 22 is manually rotated as described above, so that the screen 5 is rotated.
Although the above image is finely adjusted, even if the stickiness of the viscous material 24 tries to rotate the second rotation holder 24 by rotating the operation ring 22, the second rotation holder 21 will not be moved to the position shown in FIG. Since it remains stationary due to the resistance force of the solenoid lever 13a and the tension spring 12 shown in (), it does not adversely affect the components that control the automatic rotation. Further, when the operator finely adjusts the image, the resistance of the viscous material 24 gives the operator a comfortable operation feeling.

Another embodiment of the present invention will be described below. The same components as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

In the first embodiment, it was necessary to set the resistance of the viscous material 24 to be always smaller than the tension of the tension spring 12. Because, if the resistance of the viscous material 24 becomes larger,
In (b), when the manual rotation is performed in the counterclockwise direction, the tension spring 12 cannot withstand the force, and the second rotation holder 21 is also connected and rotated, so that the fine adjustment of the image inclination cannot be performed. This is because problems will occur.

However, the viscosity of the viscous material is easily affected by the ambient temperature and its management is difficult. Second
The third embodiment solves this. (Second Embodiment) In FIG. 3, a solenoid 41 is provided in addition to the first embodiment shown in FIG. Normally, by keeping the solenoid 41 off, the counterclockwise rotation of the second rotation holder can be restricted. The same operation as in the first embodiment can be performed by turning on the solenoid 41 only when performing the automatic rotation print. Here, the arms 11a and 11b, the solenoids 13 and 4
Reference numeral 1 constitutes a holding means 18. In this example, the solenoid is used as the structure for restricting the rotation, but other various application examples such as a motor and a mechanical lever can be considered. (Third Embodiment) In FIG. 4, by using the compression spring 30, a frictional force is generated at the contact portion F between the first rotary holder 20 and the second rotary holder 21, and the viscous viscosity is obtained. It is used as a resistance that changes to wood. As a result, it becomes possible to easily manage the resistance force regardless of the ambient temperature. Here, the compression spring 30 and the abutting portion F form an engaging means 28. (Fourth Embodiment) FIG. 5 shows a fourth embodiment of the present invention.
In this embodiment, the first rotation holder 20 can be moved up and down with respect to the second rotation holder 21.

This is because the lens may move up and down when the lens is exchanged, the film is exchanged, or the like, and the lens may collide with the first rotary holder 20 and either of them may be damaged. is there.

FIG. 5B shows the operating ring 22 as shown in FIG.
It is as seen from the direction.

In this embodiment, the operating ring 22 is made of a material such as resin that can be used as a spring material, and the arc-shaped hole 3 is formed.
By providing a plurality of 1, the spring property is provided in the vertical direction.
As a result, the first rotation holder 20 can be moved up and down, and the positional accuracy of the first rotation holder 20 can be reliably ensured even when returning to the original position.

Furthermore, when the first and second rotary holders 20 and 21 are assembled, the spring portion allows the first rotary holder 20 and the second rotary holder 20 to be connected to each other.
If the height C of the engaging portion 29 of the second rotation holder 21 is set so that a residual pressure is applied between the rotation holders 21,
It also replaces the viscous material (of the first embodiment) and the compression spring (of the third embodiment). That is, the portion where the engaging portion 29 contacts the first rotation holder and the engaging portion 29 form the engaging means 28.

As described above, it is apparent that the use of the present invention is not limited to that of the embodiment, but can be applied to, for example, an apparatus for performing automatic rotation by a stepping motor. (Fifth Embodiment) FIG. 6 shows a schematic view of a reader printer according to a fifth embodiment of the present invention.
