Will not be imaged.
[0035]
[Variation of positioning mechanism (1)]
As shown in FIG. 5, the printing apparatus 20 is different from the printing apparatus 10 in the positioning mechanism. A liquid crystal side positioning mark 36 for positioning the printing apparatus 20 is pasted below the liquid crystal screen 14 of the general-purpose mobile phone 32 by the user. (This affixing method will be described later.) Then, a contact plate 38A that is in close contact with the periphery of the liquid crystal side positioning mark 36 is formed on the printing device casing 38 of the printing device 20. The contact plate 38A is provided with a see-through portion 38B through which the positioning mark 36 can be seen, and the see-through portion 38B is formed with a printing-side positioning mark 42 that overlaps the positioning mark 36 and forms a predetermined shape.
[0036]
Here, the shapes of the liquid crystal side positioning mark 36 and the printing side positioning mark 42 will be described.
[0037]
As shown in FIG. 6A, the printing-side positioning mark 42 is composed of four triangles 42B forming a substantially X-shaped blank portion 42A, and the liquid crystal-side positioning mark 36 is an x-type that fits in the blank portion 42A. I am doing. When the center portion of the liquid crystal side positioning mark 36 and the center portion of the blank portion 42A coincide with each other, it is indicated that the incident window 22 (see FIG. 11) is positioned with respect to the liquid crystal screen 14, and FIG. As shown in b), when the center portion of the liquid crystal side positioning mark 36 is shifted from the center portion of the blank portion 42A, the position of the incident window 22 (see FIG. 11) is shifted with respect to the liquid crystal screen 14. Is shown.
[0038]
Further, as shown in FIGS. 7A and 7B, the liquid crystal side positioning mark 37 has a round shape, the printing side positioning mark 43 has a circular shape, and a protrusion 43A is provided uniformly toward the center. The same effect can be obtained with the product. 8A and 8B, a white triangle mark group 39 is provided on the mobile phone side, and a black triangle mark group 45 is provided on the printing apparatus side. You may match | combine so that three vertices may correspond.
[0039]
Here, a method of attaching the liquid crystal side positioning mark 36 to the liquid crystal casing 46 will be described.
[0040]
As shown in FIG. 9, a sticking jig 44 is used to stick the liquid crystal side positioning mark 36 (see FIG. 5) to the liquid crystal casing 46. The sticking jig 44 is a rectangular thin plate made of resin, aluminum, or the like, and has a hole 44A that is substantially the same as the shape and size of the liquid crystal screen 14 and the same shape as the liquid crystal side positioning mark 36, and is a hole that is made one size larger. 44B is formed.
[0041]
As shown in FIG. 10, first, the sticking jig 44 is brought into close contact with the periphery of the liquid crystal screen 14 by aligning the hole 44 </ b> A with the outer edge of the liquid crystal screen 14. Then, the liquid crystal side positioning mark 36 is attached to the liquid crystal casing 46 through the hole 44B. Thus, the liquid crystal side positioning mark 36 can be easily attached to a predetermined position of the liquid crystal casing 46 with the liquid crystal screen 14 as a reference.
[0042]
As described above, the liquid crystal side positioning mark 36 is attached to the liquid crystal casing 46 by using the attaching jig 44, so that it is compatible with a general-purpose mobile phone 32 that does not have a mechanism for positioning the printing apparatus 20. It becomes possible.
[0043]
Further, as shown in FIG. 11, four rubber plates 52 are provided around the entrance window 22. The rubber plate 52 absorbs an impact when the incident window 22 is in close contact with the liquid crystal screen 14 and prevents the printing apparatus casing 38 and the liquid crystal casing 46 from slipping due to the frictional force of the surface of the rubber plate 52. ing. For this reason, the position of the incident window 22 does not shift with respect to the liquid crystal screen 14.
[0044]
[Shutter]
FIGS. 12, 13A, and 13B show the shutter 24 shown in FIG. 3 in detail. As shown in FIG. 12, a bellows 56 is provided facing the entrance window 22. An opening is formed in the bellows 56 in the width direction, and a lens array 58 in which Selfoc lenses (product names) are closely arranged in a straight line is attached to the opening. This lens array 58 is movable in the direction in which the bellows 56 expands and contracts.
[0045]
That is, the lead screw 62 and the guide bar 64 extend in a direction perpendicular to the longitudinal direction of the lens array 58, and one end portion of the lens array 58 in the longitudinal direction is connected to the lead screw 62 and the guide bar 64 by the connecting members 66 and 67. Has been. The connector 66 is internally threaded and meshes with the lead screw 62.
[0046]
Then, when the motor 68 is operated at a rotational speed corresponding to the calculated scanning speed as described later and the lead screw 62 is rotated, the lens array 58 reciprocates in the direction of the arrow so as to face the incident window 22. The bellows 56 is expanded and contracted. A guide bar 64 and a connecting tool 57 are also provided at the other end of the lens array 58 in the longitudinal direction.
[0047]
As shown in FIG. 13A, when the lens array 58 is retracted to the right from the position facing the incident window 22, the light incident on the incident window 22 is blocked, and as shown in FIG. When the line scan 58 faces the incident window 22, the light incident on the incident window 22 is converged by the lens array 58 and imaged on the photosensitive surface of the photosensitive film F at the imaging position. As described above, since the shutter 24 is also provided with the aperture function, the space can be saved by the space of the aperture mechanism, and the printing apparatus 10 can be downsized.
[0048]
Here, a scanning method of the lens array 58 will be described. In the printing apparatus 10, after the power source 73 (see FIG. 15) is turned on, the processing routine shown in FIG.
[0049]
In step 201, negative determination is repeated until the print button 72 (see FIGS. 1 and 15) is pressed. In step 202, the photometry unit 74 (see FIGS. 4 and 15) measures the amount of light transmitted through the liquid crystal screen 14, and the exposure amount determination unit 76 (see FIG. 15) operates after the power source 73 is turned on. The exposure amount of the photosensitive surface of the photosensitive film F is determined based on the amount of light measured by the photometric unit 74.
[0050]
Then, the process proceeds to step 203. In step 203, the scanning speed calculation unit 78 (see FIG. 15) calculates the scanning speed of the lens array 58 based on the exposure amount determined by the exposure amount determination unit 76, and the scanning control unit 82 (see FIG. 15). The scanning speed calculated by the scanning speed calculation unit 78 is determined.
[0051]
Then, the process proceeds to step 204. In step 204, the scanning control unit 82 reads the previous scanning direction of the lens array 58 from the memory, and proceeds to step 205.
[0052]
In step 205, if the scan control unit 82 determines that the previous scan of the lens array 58 is a forward scan, the process proceeds to step 206. In step 206, the scan control unit 82 operates the motor 68 to cause the lens array 58 to perform reverse scanning at the scanning speed determined in step 203, thereby forming an image on the liquid crystal screen 14 on the photosensitive surface of the photosensitive film F. Then, when the lens array 58 is reverse scanned, the scanning control unit 82 stops the motor 68 to make the lens array 58 stand by, and shields the photosensitive film F from light.
[0053]
If it is determined in step 205 that the previous scan of the lens array 58 is a backward scan, the process proceeds to step 207. In step 207, the scanning control unit 82 operates the motor 68 to cause the lens array 58 to scan forward at the scanning speed determined in step 203, thereby forming an image on the liquid crystal screen 14 on the photosensitive surface of the photosensitive film F. Then, when the lens array 58 is scanned forward, the scanning control unit 82 stops the motor 68 and makes the lens array 58 stand by to shield the photosensitive film F from light.
[0054]
In step 208, the scanning control unit 82 stores the scanned direction in the memory. Finally, in step 209, the discharge roller 26 (see FIG. 3) is driven, the exposed photosensitive film F is developed and discharged, and the processing routine ends.
[0055]
As described above, when the lens array 58 is forward scanned, the lens array 58 is kept waiting until the next image formation, and the reverse scanning is performed at the next image formation, so that the photosensitive surface of the photosensitive film F is exposed except during the image formation. Is completely prevented.
[0056]
[Modification of shutter (1)]
As shown in FIGS. 16 and 17, a light shielding sheet 84 is provided on the shutter 25 of the printing apparatus 21 so as to face the entrance window 22. The light shielding sheet 84 is opened in the width direction, and a lens array 58 is attached to the opened portion.
[0057]
The light shielding sheet 84 is wound around both ends in a direction orthogonal to the longitudinal direction of the lens array 58 by a shaft 86. When the motor 68 is operated and the lead screw 62 is rotated, the light blocking sheet 84 is unwound or wound around the shaft 86 by being pushed and pulled by the lens array 58, and the lens array 58 is scanned.
[0058]
A rotational force is applied to the shaft 86 in the direction of winding the light shielding sheet 84 (in the direction of arrow A in the figure) by a spring (not shown), and the light shielding sheet 84 is applied with tension from the shaft 86. For this reason, it is possible to prevent light from entering the photosensitive surface of the photosensitive film F from the gap formed by the light-shielding sheet being loosened.
[0059]
In place of the lens array 58, the light from the liquid crystal screen 14 may be converged by the pinhole of the porous plate 88 shown in FIG. 18, and the light is formed in a line by the slit 92 formed in the light shielding sheet 84 shown in FIG. They may be converged, and a slit-like tube 94 shown in FIG. 20 is also applicable.
[0060]
[Modification of shutter (2)]
As shown in FIGS. 21 and 22, a plurality of light shielding plates 96 are slidably provided on the shutter 27 of the printing device 23. A hook 96A is formed at both ends in the width direction of the light shielding plate 96, and the light shielding plate 96 is forwardly fed by the upper and lower hooks 96A being locked.
[0061]
The lens array 58 is attached so as to connect the hook 96A. The moving mechanism of the lens array 58 is the same as in FIG. That is, when the motor 68 is operated and the lead screw 62 is rotated, the lens array 58 moves while sliding the light shielding plate 96, and the image of the liquid crystal screen 14 is formed on the photosensitive surface of the photosensitive film F in a line shape. Scan in the direction of the arrow.
[0062]
[Modified example of shutter (3)]
As shown in FIG. 23, the shutter 29 has a lattice plate 98 in which openings 98A having a size capable of converging passing light are formed at predetermined pitches in the vertical and horizontal directions, facing the photosensitive surface of the photosensitive film F. It is provided in layers. Among them, the lattice plate 98 disposed facing the photosensitive film F is slidable by the link mechanism 112 and the tension coil spring 114.
[0063]
In other words, the lower lattice plate 98 is constantly applied with an urging force in the direction of the arrow by the tension coil spring 114 and is held back. When sliding, the motor 113 is driven to rotate the link mechanism 112 to push the lattice plate 98 in the direction opposite to the urging force of the tension coil spring 114.
[0064]
As shown in FIG. 24A, when the grating plate 98 is moved so that the upper and lower openings 98A overlap, the light emitted from the backlight 18 and transmitted through the liquid crystal screen 14 and incident on the incident window 22 is emitted from the opening 98A. When the light passes through, the light is converged and imaged on the photosensitive surface of the photosensitive film F.
[0065]
Further, as shown in FIG. 24B, when the grating plate 98 is moved so that the partition wall 98B separating the opening 98A and the opening 98A overlap, the light incident on the incident window 22 is transmitted by the two grating plates 98. The photosensitive surface of the photosensitive film F is not exposed.
[0066]
As described above, since the diaphragm mechanism is provided with the shutter function, the space can be saved by the space of the shutter function, and the printing apparatus can be downsized.
[0067]
[Modification of shutter (4)]
As shown in FIG. 25, the shutter 31 has a lattice plate 116 in which rectangular openings 116 </ b> A having a size capable of converging light passing therethrough are formed at predetermined pitches in the vertical and horizontal directions on the photosensitive surface of the photosensitive film F. Is provided. A lid 116C that opens and closes the opening 116A is formed on the partition 116B that separates the opening 116A.
[0068]
A frame body 122 in which the wires 118 are stretched substantially in parallel and at the same interval as the lid 116 </ b> C is placed on the upper surface of the lattice plate 116. The frame body 122 is slidable by a link mechanism 112, a tension coil spring 114, and a motor 113, similarly to the drive mechanism shown in FIG.
[0069]
As shown in FIG. 26 (a), when the frame body 122 is moved so that the wire 118 is positioned on the partition wall 116B, the lid 116C is elastically restored and opened upright, and the light passes through the opening 116A. . As a result, the photosensitive surface of the photosensitive film F is exposed.
[0070]
Further, as shown in FIG. 26B, when the frame body 122 is moved so that the wire 118 is positioned above the opening 116A, the lid 116C is bent and closes the opening 116A. Thereby, the photosensitive surface of the photosensitive film F is shielded from light.
[0071]
[Modification of photometry method]
As shown in FIG. 2, the printing apparatus 10 performs photometry of the liquid crystal screen 14 in close contact with the liquid crystal screen 14, but as shown in FIG. 27, the printing apparatus 30 is separated from the liquid crystal screen 14 of the mobile phone 13. Even in the state, photometry of the liquid crystal screen 14 can be performed.
[0072]
A photometric method of the printing apparatus 30 will be described. In the printing apparatus 30, after the power supply 125 (see FIG. 29) is turned on, the processing routine shown in FIG. In step 301, the amount of light transmitted through the liquid crystal screen 14 is measured by the photometric unit 126 (see FIG. 29).
[0073]
Then, the process proceeds to step 302. In step 302, the negative determination is repeated until the photometry button 128 (see FIGS. 27 and 29) provided in the printing apparatus 30 is pressed.
[0074]
In step 303, the exposure amount determination unit 132 (see FIG. 29) determines the exposure amount based on the light amount measured by the photometry unit 126 when the photometry button 128 is pressed. For this reason, the amount of light transmitted through the liquid crystal screen 14 can be measured even when the printing apparatus 30 is separated from the liquid crystal screen 14.
[0075]
Then, the process proceeds to step 304. In step 304, the scanning speed calculation unit 134 calculates the scanning speed of the microlens 58 based on the exposure amount determined by the exposure amount determination unit 132.
[0076]
Then, the process proceeds to Step 305. In step 305, negative determination is repeated until the print button 136 is pressed, and the process proceeds to step 306. In step 306, it is determined whether or not a predetermined time has elapsed since the photometry button 128 was pressed. If the predetermined time has elapsed, the routine returns to the start of this routine. That is, the scanning speed of the microlens array 58 determined in step 304 is cleared.
[0077]
In step 305, as shown in FIG. 30, when the print button 136 is pressed while the printing apparatus 30 is in close contact with the liquid crystal screen 14, the process proceeds to step 306. In step 306, the scanning control unit 138 operates the motor 68 to scan the lens array 58 at the scanning speed determined in step 304. In step 308, the exposed photosensitive film F is developed and discharged by the discharge roller 26, and this routine is finished.
[0078]
As described above, since the amount of light transmitted through the liquid crystal screen 14 can be measured with the printing apparatus 30 separated from the liquid crystal screen 14, the amount of exposure can be determined based on the amount of light equal to the amount of light visually felt on the liquid crystal screen 14. As a result, the image on the liquid crystal screen 14 is imaged on the photosensitive surface of the photosensitive film F with the same brightness as that perceived by the human eye.
[0079]
For the shutters 29 and 31 shown in FIGS. 23 and 25, the exposure amount is adjusted at the opening and closing speed of the shutter, as in a normal camera.
[0080]
[Hue (Color Balance) Correction Mechanism]
As shown in FIG. 31, the printing apparatus 40 includes an R photometry unit 142R that measures R (red) light, a G photometry unit 142G that measures G (green) light, and a B photometry unit that measures B (blue) light. 142B is provided.
[0081]
Further, as shown in FIG. 32, a correction filter unit 144 is arranged facing the lens array 58. The correction filter unit 144 includes an R correction filter 144R that corrects R light, a G correction filter 144G that corrects G light, and a B correction filter 144B that corrects B light. The R correction filter 144R, the G correction filter 144G, and the B correction filter 144B each extend along the lens array 58.
[0082]
The correction filter unit 144 is supported by a slide rail (not shown) so that both ends in the longitudinal direction are slidable, and a shaft portion 144A extending from one end in the longitudinal direction is supported by the filter switching lever 146. The filter switching lever 146 is rotated by the switching motor 148, the shaft portion 144A is pushed, and the correction filter unit 144 slides. The switching motor 148 is fixed to one end of the lens array 58 in the longitudinal direction. For this reason, the correction filter unit 144 is scanned together with the lens array 58.
[0083]
Here, a method of switching the correction filter unit 144 will be described. In the printing apparatus 40, when the power supply 141 (see FIG. 34) is turned on, the processing routine shown in FIG. In step 401, the R, G, and B light amounts transmitted through the liquid crystal screen 14 are measured by the R photometry unit 142R, the G photometry unit 142G, and the B photometry unit 142B (see FIGS. 31 and 34). In step 401, the filter switching lever 146 is inclined and the correction filter unit 144 is retracted from above the lens array 58. That is, no correction filter is disposed between the lens array 58 and the photosensitive film F.
[0084]
Then, the process proceeds to Step 402. In step 402, the negative determination is repeated until the photometry button 152 (see FIGS. 31 and 34) provided in the printing apparatus 40 is pressed.
[0085]
In step 403, the hue detection unit 154 (see FIG. 34) performs liquid crystal based on the amount of RGB light measured by the R photometry unit 142R, the G photometry unit 142G, and the B photometry unit 142B when the photometry button 152 is pressed. The hue of the screen 14 (see FIG. 35) is detected.
[0086]
Then, the process proceeds to step 404. In step 404, the motor control unit 156 operates the switching motor 148 based on the hue detected by the hue detection unit 154, and any one of the correction filters is replaced with the lens array 58, the photosensitive film F, and the like as shown in FIG. Place between. For example, when the amount of R light is large, it is determined that the image is reddish, and the correction filter 144B is used to perform color correction.
[0087]
Then, the process proceeds to Step 405. In step 405, negative determination is repeated until the print button 158 is pressed, and the process proceeds to step 406. In step 406, it is determined whether or not a predetermined time has elapsed since the photometry button 152 was pressed. If the predetermined time has elapsed, the routine returns to the start of this routine. That is, the motor control unit 156 operates the switching motor 148 to retract the correction filter unit 144 from between the lens array 58 and the photosensitive film F.
[0088]
When the print button 158 is pressed in step 405, the process proceeds to step 406. In step 406, the scan controller 160 operates the motor 68 to scan the lens array 58.
[0089]
As shown in FIG. 35, the light transmitted through the liquid crystal screen 14 passes through, for example, the B correction filter 144B and enters the photosensitive surface of the photosensitive film F. Thereby, the R light transmitted through the liquid crystal screen 14 is corrected, and an image on the liquid crystal screen 14 is formed on the photosensitive surface of the photosensitive film F with an appropriate hue.
[0090]
In step 408, the exposed photosensitive film F is developed and discharged by the discharge roller 26, and this routine is finished.
[0091]
[Modification of Hue Correction Mechanism]
As shown in FIGS. 36 and 37, in the printing apparatus 50 which is a modification of the printing apparatus 40, the correction filter unit 162 is manually switched. The printing apparatus 50 is provided with a changeover switch 164 for manually changing the correction filter. This change-over switch 164 switches to a correction filter adapted to the hue characteristics of the liquid crystal screen of the mobile phone depending on the manufacturer and model.
[0092]
For example, in the case of a mobile phone of manufacturer A, no correction filter is arranged between the lens array 58 and the photosensitive film F. In the case of mobile phones of manufacturer B and manufacturer C, the R correction filter 162R is connected to the lens array 58. For example, it is arranged between the photosensitive film F and the like.
[0093]
[Aperture mechanism]
As shown in FIGS. 38 and 39, in the printing apparatus 60, a porous plate 166 in which a large number of openings 166 </ b> A having a size capable of converging passing light is formed between the incident window 22 and the photosensitive film F. Has been placed.
[0094]
As shown in FIG. 40, the perforated plate 166 has a higher opening ratio in the peripheral part than in the central part. Specifically, as shown in FIGS. 41 (a) and 41 (b), the pitch P1 of the peripheral openings 166A and the pitch P2 of the central openings 166B are equal, and the inner diameter D1 of the peripheral openings 166A is the same. It is larger than the inner diameter D2 of the central opening 166B.
[0095]
Thereby, since the peripheral part of the perforated plate 166 can pass a larger amount of light than the central part, it is possible to cancel the decrease in the light quantity in the peripheral part of the liquid crystal screen 14 due to the uneven light quantity of the backlight 18. Note that the aperture ratio refers to the aperture ratio (%) = ((the total area of the openings 166A (166B) in a predetermined range of the porous plate 166) / (the area of the predetermined range of the porous plate 166)) × 100.
[0096]
[Modification Example of Aperture Mechanism (1)]
As shown in FIG. 42, in the perforated plate 168, the aperture ratio in the peripheral portion is higher than the aperture ratio in the central portion. Specifically, as shown in FIGS. 43A and 43B, the inner diameter D1 of the peripheral opening 168A is larger than the inner diameter D2 of the central opening 168B. Further, the pitch P2 of the central opening 168B is smaller than the pitch P1 of the peripheral opening 168A.
[0097]
As a result, the image on the liquid crystal screen 14 can be imaged on the photosensitive film F with uniform brightness from the central portion to the peripheral portion, and the subject reflected in the central portion of the image on the liquid crystal screen 14 can be imaged more clearly than the peripheral portion. it can.
[0098]
Note that by gradually increasing the pitches and inner diameters of the openings 168A and 168B from the central part to the peripheral part, it becomes impossible to make a boundary between light and dark and resolution in the formed image.
[0099]
[Connection mechanism with mobile phone]
As shown in FIG. 4, a power supply terminal 170, a contact detection terminal 172, and a communication terminal 174 are provided around the entrance window 22 of the printing apparatus 10. On the other hand, as shown in FIG. 1, the mobile phone 12 is provided with a power supply terminal 176, a contact detection terminal 178, and a communication terminal 180 around the liquid crystal screen 14.
[0100]
When the incident window 22 is in close contact with the liquid crystal screen 14, the terminals are connected. When the power terminal 170 and the power terminal 176 are connected, the control unit 184 (see FIG. 44) of the printing apparatus 10 supplies power from the mobile phone 12 to the printing apparatus 10. Thereby, since it is not necessary to provide the battery in the printing apparatus 10, the printing apparatus 10 can be reduced in size by the space of the battery.
[0101]
When the contact detection terminal 170 and the contact detection terminal 178 are connected, the control unit 184 of the printing apparatus 10 detects that the incident window 22 is in close contact with the liquid crystal screen 14, and the display unit 182 ( The display of FIG. 1) is blinked. Thus, the user can confirm that the incident window 22 is in close contact with the liquid crystal screen 14.
[0102]
Further, when the communication terminal 174 and the communication terminal 180 are connected, image information (brightness, hue, etc.) on the liquid crystal screen 14 is communicated from the mobile phone 12 to the control unit 184 of the printing apparatus 10. As a result, it is not necessary to provide the photometric function and the hue detecting function in the printing apparatus 10, so that the printing apparatus 10 can be simplified.
[0103]
If the control unit 184 of the printing apparatus 10 turns on the power supply unit 185 (see FIG. 44) of the printing apparatus 10 when each terminal is connected, the printing apparatus 10 need not include a power switch. Parts cost can be reduced.
[0104]
[Modification of print button position]
As shown in FIG. 1, in the printing apparatus 10, the print button 72 is provided on the back surface of the printing apparatus 10, but in the printing apparatus 70, the print button 73 is located around the entrance window 22 as shown in FIG. 45. Has been placed. For this reason, in the printing apparatus 70, when the entrance window 22 is brought into close contact with the liquid crystal screen 14, the print button 73 is pushed.
[0105]
When the print button 73 is pushed, the control unit 75 opens the shutter 25 (see FIG. 46). Thus, when the incident window 22 is brought into close contact with the liquid crystal screen 14, an image of the liquid crystal screen 14 is automatically formed on the photosensitive surface of the photosensitive film F.
[0106]
[LCD screen control method]
So far, the printing apparatus has been described with respect to the printing apparatus that adjusts the exposure amount and corrects the hue. However, the specification can be applied to the printing apparatus 80 having a simple configuration that does not have the functions of adjusting the exposure amount and correcting the hue. The control method of the mobile phone 186 (see FIG. 47 for the printer 80 and the mobile phone 186) will be described.
[0107]
When the mobile phone 186 is turned on, the processing routine shown in FIG. 48 is executed, and the process proceeds to step 501. In step 501, the control unit 188 (see FIG. 49) displays the liquid crystal screen 14 in a normal state.
[0108]
Then, the process proceeds to Step 502. In step 502, the control unit 188 repeats negative determination until the print mode button 190 (see FIG. 47) is pressed. When the print mode button 190 is pressed, the process proceeds to step 503. In step 503, the control unit 188 displays the image on the liquid crystal screen 14 in a horizontally reversed manner. As a result, when the light transmitted through the liquid crystal screen 14 is directly incident on the photosensitive surface of the photosensitive film F, an image on the liquid crystal screen 14 is formed in the correct direction. Therefore, since it is not necessary to provide the printing apparatus 80 with a mirror that changes the direction of light, the printing apparatus 80 can be downsized.
[0109]
Then, the process proceeds to step 504. In step 504, the control unit 188 switches the display parameter table such as the color balance, γ correction curve, and backlight voltage of the liquid crystal screen 14 to conditions suitable for printing on the photosensitive film F. As a result, the image on the liquid crystal screen 14 is formed on the photosensitive film F with appropriate brightness and hue without adjusting the exposure amount or correcting the hue on the printing apparatus 80 side.
[0110]
Then, the process proceeds to Step 505. In step 505, when the print mode button 190 is pressed, the routine returns to the start. That is, the print mode is canceled by the control unit 188, and the liquid crystal screen 14 is in a normal display state.
[0111]
If the print mode button 190 is not pressed, the process proceeds to step 506. In step 506, it is determined whether or not a signal is sent from the communication terminal 174 to the communication terminal 180 and printing is completed, and the negative determination is repeated until the printing is completed. The liquid crystal screen 14 is switched to normal display. This routine ends.
[0112]
[Modified example of liquid crystal screen control method (1)]
As shown in FIG. 50, in the cellular phone 192 having a specification corresponding to the printing apparatus 80 having a simple configuration that does not have the exposure adjustment and hue correction functions, the processing routine shown in FIG. 51 is executed when the power is turned on. Then, the process proceeds to step 601. In step 601, the control unit 194 (see FIG. 52) displays the liquid crystal screen 14 in a normal state.
[0113]
Then, the process proceeds to step 602. In step 602, the control unit 194 determines whether or not the contact detection terminal 172 (see FIGS. 50 and 52) of the printing apparatus 80 and the contact detection terminal 178 (see FIGS. 50 and 52) of the mobile phone 192 are connected. To do. When the contact detection terminal 172 and the contact detection terminal 178 are connected and it is detected that the entrance window 22 is in close contact with the liquid crystal screen 14, the process proceeds to step 603.
[0114]
In step 603, the control unit 194 receives the detection signal and displays the image on the liquid crystal screen 14 in a horizontally reversed manner. Then, the process proceeds to Step 604. In step 604, the control unit 194 switches the display parameter table such as the color balance, the γ correction curve, and the backlight voltage of the liquid crystal screen 14 to conditions suitable for printing.
[0115]
Then, the process proceeds to Step 605. In step 605, the negative determination is repeated until the print button 193 (see FIG. 52) is pressed. When the print button 193 is pressed, the printing process is performed. Thus, the image on the liquid crystal screen 14 is formed on the photosensitive film F with appropriate brightness, hue, and the like without adjusting the exposure amount, correcting the hue, and the like on the printing apparatus 80 side.
[0116]
Then, the process proceeds to Step 606. In step 605, negative determination is repeated until the contact between the contact detection terminal 172 and the contact detection terminal 178 is disconnected, and the display parameter table on the liquid crystal screen 14 is maintained under conditions suitable for printing. When the detection signal is interrupted, the routine returns to the start. That is, the print mode is canceled and the liquid crystal screen 14 is in a normal display state.
[0117]
In the mobile phone 192, the display state of the liquid crystal screen 14 is switched by connecting and disconnecting the contact detection terminal 172 and the contact detection terminal 178. However, the present invention is not limited to this. By connecting and disconnecting the power terminal 170 of the printing device 80 and the power terminal 176 of the mobile phone 192 or by connecting and disconnecting the communication terminal 174 of the printing device 80 and the communication terminal 180 of the mobile phone 192. The display state of the liquid crystal screen 14 may be switched.
[0118]
[Modified example of LCD screen control method (2)]
As shown in FIGS. 53 and 54, a method of controlling the liquid crystal screen 15 in the digital camera 13 having the liquid crystal screen 15 larger than the size of the photosensitive film F accommodated in the printing apparatus 90 will be described.
[0119]
In the digital camera 13, when the contact detection terminal 172 of the printing device 90 and the contact detection terminal 178 of the digital camera 13 are connected as in the mobile phone 192 described above, the liquid crystal screen 14 is displayed in reverse horizontally and displayed for printing. Switch to parameter table. At the same time, as shown in FIGS. 55A and 55B, the image size of the liquid crystal screen 15 is reduced to match the size of the photosensitive surface of the photosensitive film F. As a result, the entire image on the liquid crystal screen 15 can be formed on the photosensitive surface of the photosensitive film F.
[0120]
At this time, processing information of the printing apparatus 90 such as the remaining number of photosensitive films F of the printing apparatus 90, that the printing apparatus 90 is printing, and the remaining printing time of the printing apparatus 90 is displayed in the margin portion 15A of the liquid crystal screen 15. indicate.
[0121]
As shown in FIG. 56, a bar code 15B is displayed in the margin 15A and is read by the line sensor 196 of the printing apparatus 90, and information such as the brightness and hue of the image on the liquid crystal screen 15 is transmitted to the printing apparatus 90. To do. Then, the exposure control unit 195 of the printing apparatus 90 controls the opening time of the shutter 197 (see FIG. 57) and the hue control mechanism 199 based on the information of the barcode 15B.
[0122]
Instead of the bar code 15B, as shown in FIG. 58, the light and darkness of the data display portion 15C of the margin portion 15A is read by the sensor 198 of the printing device, and the image information on the liquid crystal screen 15 is transmitted to the printing device 90. Anyway.
[0123]
As described above, the present invention has been described by taking as an example a printing apparatus that prints an image on a liquid crystal screen in close contact with the liquid crystal screen. However, the “display screen” is not limited to a liquid crystal screen, and an organic EL (Electro Luminescence) display screen or the like. Others are also applicable.
[0124]
【The invention's effect】
Since the present invention has the above-described configuration, in a printing apparatus that forms an image of a display screen on a photosensitive surface of a photosensitive material that is in close contact with the display screen and is housed in a housing, the photosensitive surface of the photosensitive material is not used during image formation. The light can be shielded and light can be incident on the photosensitive surface of the photosensitive material only during image formation.
