2. Description of the Related Art Conventionally, various types of printing devices such as printers and hard copy devices have been sold.
Since there is no additional monitor device for monitoring a print body to be printed or copied, it is necessary to prepare a monitor device specially provided outside the print device.

Further, as a reader printer for enlarging and displaying an image recorded on a microfilm or the like and printing it to obtain a hard copy, JP-A-3-1029.
The configuration shown in Japanese Patent No. 81 is known. FIG. 10 shows the conventional configuration of the publication, but this configuration will be briefly described.

In FIG. 10, a light source 10 such as an illumination lamp
The image of the roll-shaped microfilm 101 irradiated with 0 or the like is enlarged and projected by the imaging lens, and the projected light is scanned by the scanning mirror 1.
02, the optical path switching mirror 103 and the reflecting mirror 104 are projected from the rear surface of the screen 105 to perform enlarged display. When a hard copy of the display screen is required, the optical path switching mirror 103 is indicated by a broken line. And move it to

2 to obtain a hard copy of the displayed image.

However, in this configuration, a large screen 10 for enlarged projection is provided outside the printer for obtaining a normal hard copy.
It also requires an optical system including 5 and is not suitable for carrying. In order to eliminate such a defect, Japanese Patent Laid-Open No. 10298/1993
In the publication No. 1, the optical path of the image reading system path and the optical path of the image output system path are shared, and the line sensor of the image reading system path and the area sensor for display are separately provided to increase the resolution at the time of hard copy printing. A reader printer is disclosed.

Even in the reader printer shown in the above-mentioned conventional structure, the size thereof is about the size of a desktop type, and particularly, an image desired to be obtained by monitoring an image of a video camera or the like which has already been taken outdoors can be obtained. No printing device has yet been proposed that can be easily exposed to obtain a hard copy.

To meet such demands, the present applicant has previously proposed a printing apparatus as shown in FIG. Figure 11
First, when a hard copy is to be obtained, the film pack insertion lid is opened and the film pack 2 containing the instant photosensitive film is inserted into the chassis 60. Of course at this time
The photosensitive surface of the first silver salt film is ready for exposure.

At this time, the mirror opening / closing motor 66 is arranged so that the first mirror 4a constituting the optical path switching means 4 is arranged at a position inclined by 45 ° with respect to the display screen of the display means 1 as shown by the solid line in FIG. It can be rotated with. That is, the spur gear 68 fitted to the motor shaft is the spur gear 69 fitted to the shaft 70 of the first mirror 4a.
And is rotated by the motor 66. Therefore the light source 3
At the same time, the chassis 6 with the L metal fittings 72 that becomes the subject image
The image displayed on the display unit 1 fixed to 0 (the image selected by the monitor unit described later) is reflected by the first mirror 4a and enters the optical path such as a lens in the optical block 71.

The light emitted through the optical system block 71 is incident on the second mirror 5 through the R, G, B filters, and the light reflected by the second mirror 5 is incident on the third mirror 6. Then, the photosensitive surface of the film pack 2 is exposed through the opening window 65 by the third mirror arranged at an inclination. The image thus exposed is developed by the developing solution being pushed out from the inside of the chassis 60 by the roller 61 provided in the lid for inserting the film pack, and the printing paper as a hard copy is discharged from the lid 55. The dark box 73 is fixed on the sub chassis 66a.

When the image contents of the CRT, that is, the image to be printed out, is to be monitored, the first mirror 4 of the optical path switching means 4 is rotated to the position shown by the broken line in FIG. The image content of the display means 1 can be viewed directly.

[0011]

According to the configuration of FIG. 11 described as the conventional configuration, the display device which becomes the subject image rotates the first mirror 4a without providing a monitor display device. This makes it possible to directly monitor the display device. However, there is a problem that it is difficult to monitor because the CRT of the display device that can be monitored has a display screen as small as about 1 inch.

The present invention is intended to provide a printing apparatus which solves the above problems, and its object is to carry a portable image capable of monitoring a subject image at least in substantially the same area as the photosensitive surface of the instant photosensitive film. It is intended to obtain a mold printing apparatus.

[0013]

As shown in FIG. 1, an example of the printing apparatus of the present invention is a film which is stored in a film pack 2 as a light source 3 using an image displayed on a display unit 1. In a printing apparatus that exposes and prints on a sheet, first moving means 150 for moving the film pack 2, a display member 151 having substantially the same angle of view as the film pack, and a display member 1
51 is provided with second moving means 152 for moving the first
The display member 151 is moved by the second moving means 152 after (time) the movement of the film pack 2 via the moving means 150, and the image on the display means 151 is monitored.

[0014]

The printing apparatus of the present invention is configured such that the image projected on the light source / display means 1 such as a CRT is exposed through an optical system onto an instant photosensitive film of an instant film pack in which exposure and development are integrated. , When the discharge of the film pack is completed (or during discharge), the screen is brought to the exposure position of the instant film pack,
Since the image displayed on the light source / display means 1 can be monitored through an optical system, the monitor image can be magnified to be substantially the same size as the exposed hard copy. Is obtained.

The photosensitive layer is exposed to each of R, G, and B colors in a frame sequential manner. Further, the system controller 136 supplies a control signal to the filter feed motor drive circuit to drive the filter feed motor 76 so that the R filter 84R is brought to the initial position, that is, in the optical path, and stops the filter feed motor 76.

Next, the first and second moving motors 66 are driven through the first and second moving means motor driving circuits 137 to drive the first driving means, that is, a film pack (tray).
The moving means 150 is moved to the upper moving state position of FIG. 5, and the screen moving means 152 which is the second moving means is moved to the enlarged projection possible state position of FIG. During this time, the user waits for the print image to be ejected from the lid 55 as shown in the sixth step ST ₆ .

In the next seventh step ST ₇ , as shown in FIG. 2, at the stage where the print sheet is discharged, the developing solution in the bag of the film pack 2 is pressed by the rollers 61 and 61 in the lid 55 to spread it uniformly. For film feed motor drive circuit 1
A control signal is supplied from 39 to the system controller 136, and a film feed motor 140 (not shown) is rotationally driven.

In the next eighth step ST ₈ , by waiting for the development for several seconds to several minutes, the development is completed and the exposed and developed hard copy can be taken out. Of course, in the above-mentioned configuration, the CRT is mounted so that the right and left sides can be correctly monitored or printed.
The scanning directions of the horizontal and vertical deflection systems 126 are reversed.

It becomes a display screen, and a compact and portable printing device can be obtained. In particular, it is possible not only to immediately check the image taken by a video camera etc. at the time of shooting, but also to see the monitor image in the same size as the print image. As a result, a printing device that is extremely easy to see can be obtained.

In the above embodiment, the case where the drive control of the first and second moving means 150 and 152 is performed by the motor 66 (or 66A) has been described. However, for example, as shown in FIG.
On the upper surface of the handle 151, which is locked to one end of the screen 151.
175 formed on the upper plate of the housing 50
Obviously, the tray 154 may be manually moved along the same direction, and the tray 154 may be manually inserted / removed in the same manner. Further, the display means 1 is not limited to the CRT and may be an LCD or the like.

FIG. 9 shows another structure of the printing apparatus of the present invention. The parts corresponding to those in FIG. 1 are designated by the same reference numerals and their duplicate description will be omitted. The film pack (tray) moving means 150 is slid vertically (up and down) with respect to the panel 51 of the housing 50, and the screen 151 is moved by the second screen moving means 152.
It was slid horizontally (left and right) with respect to the screen 1 in FIG.
51 is arranged so as to be independently movable horizontally (left and right) with respect to the panel 51 by the first and second moving means 150 and 152. Further, a light shielding plate 177 is arranged so as to cover the display window 52 of the panel 51 from the back surface, and this light shielding plate 177 is also configured to be slidable in the horizontal (left and right) direction of the panel 51 manually or the like. Therefore, a third moving means may be provided.

In the case of monitoring the projected image on the display means 1 with the above-mentioned structure, the screen 151 is moved by the moving means 152 in the direction of arrow c, and the light shielding plate 177 is moved by the third moving means in the direction of arrow D '. Bring a light shield 177 behind the panel 51 on the front of the tray 154. In this state, the projection light from the display means 1 emits the first to third mirrors 4a, 5,
The image is projected onto the screen 151 via the display 6, and the user can monitor the image via the display window 52.

Next, in order to expose the instant photosensitive film of the film pack 2 in the tray 154, the light shielding plate 177 is used.
At the same time, the tray 154 is moved together in the directions of arrows D and C so that the light from the display window 52 is not irradiated, and the screen 151 is moved by the second moving means 152 in the direction of c ′ to perform exposure. You may choose to get a copy.

Further, the tray 154 can be opened and closed by pivoting to the front side like a door with respect to the housing 50 via a hinge or the like, and the screen 151 can be slid horizontally (left and right) with respect to the panel 51. You can also do it.

[0067]

According to the printing apparatus of the present invention, a compact CRT is provided.
The image projected on the screen is used as the print original image (subject image) of the color video signal, and CR is used for monitoring.
Since the image projected on the CRT projected on the screen where T is magnified and projected can be used, the monitor display image becomes large and easy to see, so that the image monitor can be as large as the angle of view of the print image. Since it is possible to downsize the device, it is not necessary to provide a separate monitor in the printer device. Therefore, a printing device that can be taken outside with a camera-integrated VTR or the like to easily obtain a necessary hard copy is provided. can get.
