[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image recording apparatus which exposes an image on a photosensitive member by a light source and records the image using the exposed image.

[0002]

2. Description of the Related Art An image recording apparatus (Japanese Patent Laid-Open No. 2-193133) having a slide mechanism, which is the basis of the present invention, will be described with reference to FIG.

As shown in FIG. 9, a slide rail 50 is provided on a tray 502 which is projected to the side of the apparatus main body 500.
A light source unit 508 for transmission exposure having a roller 510 corresponding to No. 4 is placed, and when recording an image of a transmission original, the light source unit 508 is manually operated along the slide rail 504 to place the original. It is moved to and held on the table 550. At this time, the original placing table cover for the reflected original is removed from the original placing table 550 and mounted on the tray 502.

In this state, the light source stored in the light source unit 508 can be scanned within the light source unit 508 to expose the transparent original through the bottom surface of the light source unit 508.

[0005]

However, in the above-mentioned conventional image recording apparatus, since the transmissive exposure light source and the driving unit 508 for scanning the transmissive exposure light source are integrated, the entire unit is complicated and large. However, there is a problem that the storage space when the transmission exposure is not performed is largely protruded to the side of the document table 500. In order to solve this, in the above-mentioned conventional technique, the entire drive unit 508 can be removed, but the handling becomes complicated.

Further, since it is necessary to manually move the unit 508 to the exposure position by the slide mechanism every time it is necessary to expose the transparent original, there is a problem that copying cannot be performed by a simple operation as in the case of reflection exposure. There was a point.

Further, since it is necessary to mount or remove the original placing table cover so as not to interfere with the driving unit 508 every time the transmission exposure / reflection exposure is switched, there is a problem that it takes time and effort.

The present invention has been made to solve the above-mentioned problems of the prior art, and an object of the present invention is to record a transparent original and a reflective original by a simple operation without taking a complicated apparatus configuration. To obtain an image recording device that can.

[0009]

According to a first aspect of the present invention, there is provided an image recording apparatus capable of recording images of a transparent original and a reflective original placed on a transparent original placing table, which is below the original placing table. And a transmission exposure light source for scanning and exposing a document placed on the document placing table, a transmissive exposure light source for scanning and exposing a document placed on the document placing table, and one side on the document placing table. And driving means for supporting the transmissive exposure light source and moving the transmissive exposure light source from one end to the other end on the original placing table.

According to a second aspect of the present invention, in addition to the first aspect of the invention, in the case of reflection exposure, the light source for transmission exposure is retracted to a retracted position where it does not interfere with the document placing table cover for pressing the reflection document. In the case of transmissive exposure, there is provided control means for moving the transmissive exposure light source from the retracted position to the exposure start position and then scanning the exposure range.

According to a third aspect of the present invention, in addition to the second aspect of the invention, the original document placed on a document is rotated from a rotational position that interferes with a scanning locus of the transmissive exposure light source that scans and exposes an exposure range to a rotational position that does not interfere. The document table includes a table cover and a biasing unit that biases and rotates the document table cover toward the document table when the document table cover is in the pivoting position where the document table cover interferes.

According to a fourth aspect of the present invention, in addition to the third aspect of the invention, a detecting means for detecting a contact state of the original placing table cover with the original placing table, and the abutting state is detected by the detecting means. And a prohibiting means for prohibiting driving of the driving means.

[0013]

According to the invention of claim 1, the driving means for the light source for transmissive exposure is arranged along one side of the document table,
Since the transmissive exposure light source is moved from one side of the document placing table to the other side, it is not necessary for the transmissive exposure light source to largely protrude to the side of the document placing table and stand by when exposing the reflective original.

According to the second aspect of the invention, in the case of reflection exposure, the light source for transmission exposure is retracted to the retracted position. Therefore, the light source for transmissive exposure does not hinder the pressing of the original by placing the original placing table cover of the reflective exposure on the original placing table.

According to the third aspect of the present invention, when the original placing table cover is in the rotating position where it interferes with the transmissive exposure light source, it is biased and rotated toward the original placing table, so that the original placing table cover is exposed. Therefore, it does not interfere with the transmissive exposure light source that moves. Therefore, the document table cover and the transmissive exposure light source will not accidentally interfere with each other to prevent a recording error.

According to the fourth aspect of the invention, the detecting means detects a state in which the platen cover is in contact with the platen. In this case, since it is necessary to perform reflection exposure, the prohibiting means prohibits the driving of the driving means.

As shown in FIG. 3, inside the transmissive light source unit 350, the transmissive lamp 3 is used as a light source for transmissive scanning exposure.
52 is attached. The transparent lamp 352
Can be adjusted up and down and left and right by a variable plate and screws (not shown), and it is possible to correct mechanically generated variations in the mounting position of the transmissive lamp and positional deviation of the filament.

Above the transmissive lamp 352, reflectors 354A and 354B that reflect the light of the lamps are mounted, and the upper portions of these two reflectors are opened in order to dissipate the heat generated from the transmissive lamp 352. A temperature fuse (not shown) is attached to the lower portion of the reflector 354B. When the temperature at the attached position reaches a predetermined temperature, the temperature fuse is cut off so that the transmission lamp 352 does not rise above the predetermined temperature. Has become.

A fan unit 356 is attached to the upper portions of the reflectors 354A and 354B.
The heat generated by the transmissive lamp 352 is transferred to the transmissive exposure unit 35.
It's running out of 0. A temperature sensor 360 is attached to the upper portion of the reflector 354B. Therefore, when a temperature control circuit (not shown) mounted on the transmissive light source unit 350 detects a predetermined temperature, the fan unit 35

In the case of this transmissive exposure, the halogen lamp 38A and the slit plate 38 are used as in the case of the reflective exposure.
B, the mirror unit 38C moves in synchronization with the moving speed of the transmissive exposure unit 350. In this case, in the case of transmissive exposure, since the transmissive lamp 352 is used as a light source, it is not necessary to turn on the halogen lamp 38A for reflective exposure. However, for example, characters are written on the plastic frame of the slide film. If the lights are turned on at the same time, it is possible to expose not only the film as the transparent original but also the characters written on the plastic frame as the reflective original, and both the transparent and reflective originals can be recorded.

By selecting a button (not shown) on the operation panel 44 according to the exposure state of the transparent original 308, the control circuit (not shown) in the machine base 12 causes the exposure unit 22 to operate.
Controlling an aperture opening / closing device (not shown) positioned in front of the control unit, and the control circuit sends a signal to a speed control circuit (not shown) on the substrate 306, and the speed control circuit controls the moving speed of the transmission exposure unit 350. Thus, proper exposure becomes possible.

On the other hand, when copying by reflection exposure, since the transmission exposure unit 350 is stored in the unit holders 390A and 390B as described above, it does not interfere with the pressing cover 400 used during reflection exposure. (Description of the pressing cover 400) This pressing cover 400
The hinge mechanism 406 of FIG. 6 will be described in more detail. As shown in FIG. 6, the shaft support pin 4 is attached to the block 406A in which the cylindrical leg portion is inserted and supported in the pressing cover support 408 which is fixed and supported.
06E is penetrated. The long hole 4 of the bracket 409 fixed to the pressing cover 400 is attached to the shaft support pin 406.
It has been inserted into 09A.

On the other hand, the flange 407 of the flanged shaft 406B, both ends of which are inserted into the slot 409A, is the block 4
The cam surfaces 407B, which are housed in the groove 407A of 06A and are formed on both sides of the groove 407A, hit the flanged shaft 406B. A spring 406D and a shaft 406C for urging the flanged shaft 406B toward the cam surface 407B are provided inside the pressing cover 400. Cam surface 407B
Is a circumference of an approximately 1/4 circular arc, and a circumferential intermediate portion 407 thereof.
The radius of C is the maximum.

In the figure, R indicates a constant radius. Therefore, the spring 4
The pressing force of 06D is applied to the pressing cover 4 when the flanged shaft 406B is in the direction of arrow B with the circumferential intermediate portion 407C as a boundary.
00 is lifted, and when it is on the side opposite to the arrow B direction, the pressing cover 400 is lowered.

Therefore, the pressing cover 406 rotates about the shaft 406 with the flange, and as shown in FIG. 5, the maximum release (lift) position P and the transmission exposure unit 3 are set.
In the range FS between the movement locus of 50 and the intermediate position Q immediately before the position interferes, the gravity of the pressing cover 400 and the spring 40
The lifting force by 6D is balanced and stopped at an arbitrary position (free stop range), or the lifting force by spring 406D is excellent and the pressing cover 400 is lifted, and the intermediate position Q
At the contact position with the original placing table 12A, that is, the position where the pressing cover 400 interferes with the movement trajectory of the transmissive exposure unit 350 (closeable range), the spring 406D further lowers the pressing cover 400 in addition to its own weight. To work.

Further, as shown in FIG. 5, a magnet 402 is attached to the pressing cover 406,
When the pressing cover 406 comes into contact with the placement table 12A and stops during the reflection exposure, the reed switch 316 attached to the drive unit is turned on by the magnetic force of the magnet 402.

Therefore, as shown in FIG. 7, the control circuit 50 in the machine base 12 which has obtained the information of the reed switch 316 and the information of the operation panel 44 is the control circuit 306A on the substrate 306 in the drive unit 300. Is controlled so that the transmission scanning exposure cannot be performed in the reflection original mode. (Operation of Embodiment) Next, the operation of the image recording apparatus 10 and the operation of this embodiment will be described.

When performing copying by transmission exposure by the image recording apparatus 10, after the pressing cover 400 is rotated to the free stop range and the transparent original 380 is set on the transparent glass plate 45 with the image surface facing downward. When the transmission exposure switch of the operation panel 44 is pressed, transmission exposure copying is started. At this time, since the pressing cover 400 is not closed, the reed switch 316 is turned off by the magnetic force of the magnet 402. Therefore, machine base 1
Even if the reflection exposure switch is pressed by the control circuit in 2,
Copying by reflection exposure is not started. Also, since the pressing cover 400 is held in the free stop range,
It does not interfere with the transmitted light source unit 350.

The board 306 mounted in the drive unit 350, which receives a signal from the control circuit in the machine base 12, sends a drive pulse to the stepping motor 308, and the stepping motor 308 which receives the pulse starts rotation. Power is transmitted to the transmissive light source unit 350.

With this power, the transmission light source unit 350
1 moves forward from the retracted position in the direction of arrow A in FIG. 1 to a predetermined position that has passed the exposure range near the right end of the document table 12A, and then moves backward from the predetermined position in the direction opposite to the direction of arrow A to the transmission exposure start position. Moving. Next, when the transmission light source unit 350 is positioned at the transmission exposure start position, the machine base 1
Power is supplied to the transmissive lamp 352 from a power supply circuit (not shown) in 2 to turn on the transmissive exposure lamp 352. As a result, a state becomes possible in which transmission scanning exposure is performed in the direction opposite to the arrow A direction.

Then, as shown in FIG. 8, the control circuit 306A of the substrate 306 sends a signal to the control circuit 50 in the machine base 12 at a predetermined timing, and the control circuit receiving the signal drives the driving device 52. Transmission light source unit 350
The halogen lamp 38A, the slit plate 38B, and the mirror unit 38C are moved at a predetermined speed in synchronization with the moving speed of the.

Therefore, the light emitted from the transmissive lamp 352 is directly or reflected by the reflectors 354A and 354B and transmitted through the original 380 and the transparent glass plate 45. Then, the transmission scanning exposure that has passed through the slit plate 38B is performed by the mirror unit 3.
8C, the lens unit 38D, the mirror unit 39, etc., and is guided to the exposure unit 22.

When the transmissive scanning exposure is completed, the transmissive lamp 352 is turned off, and the transmissive exposure unit 350 moves from the transmissive exposure end position in the direction opposite to the arrow A direction and is stored in the unit holders 390A, 390B.

On the other hand, when the image recording apparatus 10 makes a copy by reflection exposure, the original is set on the transparent glass plate 45 with the image surface facing downward, and then the pressing cover 400 is rotated to the closeable range. And holding cover 4
00 abuts on the posting table 12A by its own weight and stops.
When the reflection exposure switch on the operation panel 44 is pressed, reflection exposure copying is started.

At this time, since the pressing cover 400 is closed, the reed switch 316 is turned on by the magnetic force of the magnet 402. Therefore, even if the transmission exposure switch is pressed by the control circuit in the machine base 12, copying by transmission exposure is not started. Also, the holding cover 4
00 does not interfere with the drive unit 300, and since the transmissive light source unit 350 is retracted to the unit holders 390A and 390B, it does not interfere with the transmissive light source unit 350.

When the reflection exposure switch is pressed, the machine base 12
The control circuit therein turns on the reflection exposure lamp 38A, whereby the reflection scanning exposure is enabled. This reflection scanning exposure is performed by moving the halogen lamp 38A, the slit plate 38B, and the mirror unit 38C at a predetermined speed from a predetermined reflection exposure start position to a predetermined reflection exposure end position. That is, the light emitted from the halogen lamp 38A is reflected on the original, transmitted through the transparent glass plate 45, passed through the slit plate 38B, guided to the mirror unit 38C, the lens unit 38D, the mirror unit 39, etc., and exposed to the exposure section 22.
Be guided to.

On the other hand, when the photosensitive material magazine 14 containing the photosensitive material 16 is set, this photosensitive material magazine 1
Photosensitive material 1 pulled out from 4 and cut into a predetermined length
6 is conveyed to the exposure unit 22. The photosensitive material 16 is inverted and fed into the exposure section 22 so that the photosensitive surface thereof faces upward.

The photosensitive material 1 sent to the exposure section 22.
At 6, when passing through the exposure point between the transport roller 23 and the transport roller 24, the light subjected to the transmission scanning exposure or the reflection scanning exposure forms an image.

The photosensitive material 16 that has been exposed in the exposure section 22
After being once fed to the switchback unit 40, it is transported to the water application unit 62 by the reverse rotation of the transport roller 26. In the water application section 62, water that acts as an image forming solvent and a transfer aid is applied to the photosensitive material 16, and then excess water is squeezed and sent to the heat development transfer section 104.

On the other hand, as the photosensitive material 16 is exposed, the image receiving material 108 that has been pulled out of the receiving material magazine 106 and cut into a predetermined length is guided and conveyed by the image receiving material conveying section 180, and the heat development transfer section 104. The light-sensitive material 16
