After the multi-image signal has been written into this video memory, it is converted from the R, G, B image signal into a low-frequency luminance signal Y and a color difference signal C by the reproduction / write clock as described above, and the NTSC signal is output.
The signal is converted into a signal and written again into the video memory in the TV output signal processing unit 315. When the writing is completed, the contents stored in the video memory are repeatedly read at a predetermined cycle based on the reproduced clock from the oscillator 318.
The signals are converted into analog signals by the D / A converters 316 and 317 and output to a TV (not shown). In this way, the multi image is displayed on the TV as a still image.

In the multi-image printout, the multi-image signal written in the multi-video memory 320 as described above is converted into the printer data conversion circuit 321 shown in FIG.
Is output to the thermal head 410 after data conversion.

 Next, an internal mechanism of the printer unit 111 will be described.

FIG. 9 is a front sectional view of the printer unit 111, and FIG.
FIG. 11 is a sectional view taken along line XX of FIG. 11, and FIG. 11 is a sectional view taken along line XI-XI of FIG.

In FIG. 9, a platen roller 421 and a DC servomotor 420 for driving the platen roller 421 are disposed in the printer case 41. The platen roller 421 is disposed at a position facing the thermal head 410 when the platen roller 421 is mounted on the main body of the printer unit 4. At the upper and lower ends of the platen roller 421, grip rollers 425, 425 each having a large number of minute projections formed on the outer peripheral surface are fixed, and are configured to rotate integrally with the platen roller 421. A gear 422 is attached to the lowermost end of the platen roller 421.
It is connected to the gear 423 of the servomotor 420. The platen roller 421 is driven to rotate by the DC servo motor 420 via the gears 422 to 424.

On the other hand, other mechanisms necessary for printing are arranged in the main body of the printer unit 4.

The thermal head 410 is slidably held in the storage case 426 in the direction of arrow a so as to face the platen roller 421. A thermal head pressure contact solenoid 411 is fixed to the storage case 426, and a plunger 427 of the thermal head pressure contact solenoid 411 is connected to the thermal head 410 via a lever 428 and a shaft 429. The thermal head 410 is slidable in the direction a by a spring coil (not shown) attached around a fulcrum 430 of a thermal head pressure contact solenoid 411 and a lever 427. (Rest position). That is, the thermal head 410 is held at the above-described pressure contact position when the thermal head pressure contact solenoid 411 is on, and is held at the separated position when it is off.
A bearing structure is formed at the upper right and lower ends of the right side of the storage case 426, and the nip rollers 412, 412 are rotatably mounted so as to sandwich the thermal head 410. This nip roller 412 is pressed against the grip roller 425,
The recording paper can be accurately fed by the rotational force of the grip roller 425 and the nip roller 412.

The ink ribbon 416 is connected to the supply roller 4 as shown in FIG.
Stretched between the take-up roller 31 and the take-up roller 432, it is mounted so as to pass between the thermal head 410 and the platen roller 421 on the way, and the presence or absence of the mounting is determined by the ribbon set detection sensor 419. .

Returning to FIG. 9, a gear C is attached to the lower end of the take-up roller 432 on which the ink ribbon 416 is mounted via a slip clutch 433, and the gear C is further connected to the nip roller 412 on the lower end side via the gear B. It is connected to the mounted gear A. The slip clutch 433 always rotates the winding roller 432 at an appropriate speed regardless of the rotation speed of the nip roller 412, and performs a stable winding operation of the ink ribbon 416. The gear B is configured to mesh with the gear C when rotating in the direction f in FIG. 11 and not mesh with the gear C when rotating in the direction e in FIG.
The rotational force is transmitted to the winding roller 432 only when the 412 rotates in the g direction. That is,
To set the recording paper in a predetermined position, nip rollers 41
When the paper is conveyed in the direction b by 2,412, since the printing is not performed, the rotational force of the nip roller 416 is not transmitted to the winding roller 432 so that the ink ribbon 416 is not wound, and the recording paper is moved in the direction b by the nip rollers 412,412. When the paper is conveyed in the reverse direction, printing is performed, so that the rotational force of the nip roller 412 is applied to the take-up roller 432 so that the ink ribbon 416 is taken up.
To be communicated to.

Further, a gear E of a slit plate 434 is connected to the gear A via a gear D, and the slit plate 434 rotates in conjunction with the rotation of the nip roller 412.
Accordingly, the rotation operation of the slit plate 434, that is, the rotation operation of the nip roller 412, is detected by the rotation detection sensor 413, and based on the detection signal, in addition to the transport amount of the recording paper, printing of the thermal head 410 and ink ribbon according to the transport speed. 416
Winding is performed properly.

The ink ribbon 416 having the same width as the thermal head 410 is used. FIG. 12 shows an example of a sublimation ink ribbon, and FIG. 13 shows an example of a melting ink ribbon.

The ink ribbon for sublimation and the ink ribbon for fusing have three colors of yellow, magenta, and cyan, each having a predetermined length, which are repeatedly arranged in this order from the winding roller 432 side. A transparent portion 416a indicating the head of the ribbon is provided. Further, the transparent portion 416a is provided with a black marker m indicating the type of the ink ribbon. For example, the sublimation ink ribbon has a marker m at the right end in the winding direction (FIG. 12), and the melting ink ribbon has a marker m at the left end in the winding direction. (Fig. 13). The marker m on the left end side with respect to the winding direction of the ink ribbon 416 is detected by the ribbon cueing sensor A417, and the marker m on the right end side with respect to the winding direction of the ink ribbon 416 is detected by the ribbon cueing sensor B418. These ribbon cue sensors
Ink ribbon attached by detection signal of A417 and B418
The type of the ink ribbon 416 is determined, and cueing of the ink ribbon 416 during printing is performed. That is, the ink ribbon 416 is determined to be a melting ink ribbon when the marker m is detected only by the ribbon cue sensor A417, and is determined to be a sublimation ink ribbon when detected by only the ribbon cue sensor B418. .

Note that the position of the marker m is not limited to both ends of the transparent portion 416a, and may be provided so as to be shifted left and right with respect to the center line of the ink ribbon 416. Further, the correspondence between the position of the marker m and the type of the ink ribbon 416 is not limited to the above, and can be arbitrarily associated. The ink ribbon in FIG. 16 will be described later. On the other hand, the recording paper is also provided with a square marker M for determining the type of the recording paper. FIG. 14 shows an example of the sublimation recording paper, and FIG. 15 shows an example of the gradation thermal recording paper. The markers M are provided on the back surface of the recording paper Pa, provided on the diagonal opposite corners of the recording paper for sublimation, and provided on the gradation thermal recording paper one marker inside the both corners. Have been. In this embodiment, the marker M is not provided on the fusing recording paper. The recording paper Pa may be of a paper type, or may have a glue on the back surface.

Markers M provided at both diagonally opposite corners are detected by the recording paper detection sensor A414, and the markers M are positioned at one corner from the two corners.
The marker M provided inside the marker is detected by a recording paper detection sensor B415, and the recording paper detection sensor A4
The type of the recording paper Pa is determined based on the detection signals of 14 and B415.

Note that the position of the marker M is not limited to the above position, and may be provided at an arbitrary position on the back surface of the recording paper Pa. The correspondence between the position of the marker M and the type of the recording paper Pa is not limited to the above, and can be arbitrarily associated.

FIG. 17 is a diagram showing the internal mechanism of the printer unit when performing monochrome printing on cut sheet type recording paper,
FIG. 11 is a sectional view corresponding to FIG.

The monochrome type printer unit is configured by removing the ink ribbon 416 from the color type printer unit 111 (see FIG. 10). That is, in the monochrome type,
Printing can be performed by directly pressing the thermal head 410 against the gradation thermal recording paper. Therefore, printing can be performed only by removing the ink ribbon 416. In monochrome printing, a roll-type recording paper for gradation thermal printing can be used. In this case, instead of the ink ribbon 416, a recording paper for gradation thermal printing is used as shown in FIG. 436
Can be printed by attaching.

FIG. 18 is a view showing the internal mechanism of the printer unit 111 of the hand scan type, and is a sectional view corresponding to FIG.

Since the hand scan type does not require a drive source (DC servo motor) for the nip roller 412, the printer unit 111 is configured by detaching the printer case 2 from the camera body 1. In the hand scan, since monochrome printing is performed, a black ink ribbon 416 shown in FIG. 16 is used as the ink ribbon. Since the melting ink ribbon 416 is entirely black, a detection signal of the marker M is output from the ribbon cueing sensors A417 and B418, whereby it is determined that the melting ink ribbon 416 is black.

Next, regarding the printing operation of the printer unit 111,
The case of color printing on cut sheet type recording paper, the case of monochrome printing on cut sheet type recording paper, and the case of printing by hand scanning will be described separately.

(1) Color printing on cut sheet type recording paper In FIG. 11, when the recording paper Pa is inserted from the recording paper insertion port 42 in the direction b (the direction from the top surface to the bottom surface side of the printer unit 4), the recording paper Insertion and type of the recording paper Pa are detected by the detection sensors A414 and B415, and the DC servomotor 420 is rotationally driven in the i direction in response to the detection signal.
As a result, the grip roller 425 rotates in the direction c, and the inserted recording paper Pa moves with the grip roller 425 and the nip roller 4.
12 and transported in the direction b. On the other hand, at this time, the thermal head pressure contact solenoid 411 is in the off state, and the thermal head 410 is held at a position separated from the platen roller 421. Also, grip rollers
When the 425 rotates in the c direction, the nip roller 412 rotates in the h direction, and this rotational force is transmitted to the gear B via the gear A, and the gear B rotates in the e direction. However, since the gear B is not connected to the gear C, the winding roller 432 does not rotate, and the winding of the ink ribbon 416 is not performed.

When the rotation detecting sensor 413 detects that the recording paper Pa has been conveyed to a predetermined position, the DC servo motor 420 is stopped, and then the thermal head pressure contact solenoid 41 is turned off.
1 is turned on, and the thermal head 410 is pressed against the platen roller 421 via the ink ribbon 416 and the recording paper Pa.
Thereafter, the DC servo motor 420 is rotationally driven in the j direction,
As a result, the platen roller 421 rotates in the direction d to feed the recording paper Pa, and the thermal head 410 prints yellow image data one line at a time in synchronization with the paper feeding speed. At the time of printing, the rotational force of the nip roller 412 is transmitted to the gear B, and the gear B rotates in the f direction. As a result, the gear B is connected to the gear C, and the winding roller 432 rotates to wind the ink ribbon 416.

When the yellow printing is completed, the thermal head pressure contact solenoid 411 is turned off, and the thermal head 410 is switched to a position separated from the platen roller 421.
Thereafter, when the DC servo motor 420 is driven to rotate again in the i direction and the recording paper Pa is fed to the predetermined position in the b direction, printing of magenta image data is performed by the same operation as described above. Then, printing of magenta and cyan is sequentially performed, and when these printings are completed, the thermal head pressure contact solenoid 411 is turned off, and the thermal head 410 is switched to the separated position with respect to the platen roller 421. Thereafter, the DC servo motor 420 is driven to rotate in the j direction, and the printed recording paper Pa is conveyed in the direction of the recording paper insertion port 42 and discharged.

(2) Monochrome printing on cut sheet type recording paper Monochrome printing on cut sheet type recording paper is performed by the same operation as color printing on the cut sheet type recording paper, and black printing is performed only once. Then, the recording paper Pa is discharged from the recording paper insertion port.

(3) Printing by Hand Scan In printing by hand scan, the printer case 2 is detached from the printer unit 4 body, and the server 10 is moved to the recording paper Pa.
The camera body 1 is moved in the k direction in FIG. 18 with the hand head print switch (not shown) turned on, and the circle head 4 is used to move the camera body 1. When the printer unit 4 is moved in the k direction, the nip roller
412 rotates in the g direction. This rotation is detected by the rotation detection sensor 413, and the printing timing and printing speed of the thermal head 410 are controlled based on the detection signal, and the image data for one line is recorded on the recording paper Pa by the nip roller.
Printing is performed in synchronization with the rotation speed of 412, that is, the paper feeding speed.

In addition, when printing using the ink ribbon for fusion,
Plain paper can be used as the recording paper Pa. In this case, for example, as shown in FIG. 20, the insertion portion of the recording paper Pa can be inserted by a predetermined distance from the front side in the horizontal direction of the printer unit 4, and the groove is opened in the vertical direction of the printer unit 4. With this structure, it is possible to print out a captured image freely not only on the recording paper Pa having a predetermined size but also on the end of the ordinary recording paper Pa having an arbitrary size. This makes it possible to easily confirm a photographed image, perform simple recording, and the like, and reduce the cost of the recording paper Pa. The groove-shaped recording paper insertion portion is provided in the printer unit 4.
Not limited to the front side surface of the main body, it can be provided at any position on the rear side surface.

FIG. 21 is a diagram showing a circuit configuration of the thermal head 410.

The thermal head 410 includes an output control unit 500 that controls serial output of print data, a head driver 504 that controls print timing, and a heating resistor R corresponding to each print head.
It comprises a heating section 505 provided with 1 to R496 and a thermistor 506 for detecting a heating temperature.

The output control unit 500 includes shift registers 501 and 502 to which 248 D flip-flops (hereinafter, referred to as DFFs) are cascaded, and a latch circuit 503 for latching 496 pieces of print data. The print data is serially input to the input of the first DFF of the shift registers 501 and 502, and the Q output of each DFF of the shift register 501 is sequentially latched.
The Q output of each DFF of the shift register 502 is sequentially input to the even-numbered latch circuit in the latch circuit 503. The CLOCK signal is input to the CK input of the shift register 501, and the CLOCK signal is input to the CK input of the shift register 502 by the inverter 50.
The inverted CLOCK signal inverted in 7 is input.

496 print data are serially input to the first DFF of the shift registers 501 and 502, and each DFF of the shift register 501 is input.
From the rising edge of the CLOCK signal, the odd-numbered print data is sequentially output to the corresponding latch circuit in the latch circuit 503.Each DFF of the shift register 502 sequentially shifts the even-numbered print data at the rising edge of the inverted CLOCK signal. Latch circuit 503
Is output to the corresponding latch circuit. Then, when all print data is output to the latch circuit 503, a latch signal is input to the latch circuit 503, and print data for one line is determined.

FIG. 22 and FIG. 23 are time charts showing the operation of the output control unit 500. FIG. 22 shows the case of the melting type or the hand scan mode, and FIG. 23 shows the case of the sublimation type or the gradation thermal mode.

4 (2 × 2) in the fusion type or hand scan mode
Area) is performed using the dot data of
The print data for one line is composed of 496 pieces, and the 496 pieces of print data are output to the latch circuit 503 in synchronization with the CLOCK signal and the inverted CLOCK signal. On the other hand, in the sublimation type or gradation thermal mode, the density gradation is performed by modulating the printing energy using four (2 × 2) dot data as one surface element. , The second, third, fourth,... 495,496th adjacent data are the same data. Therefore, the same print data is input to both DFFs in the same arrangement position of the shift registers 501 and 502, and in the time chart, as shown in FIG.
Eight print data are synchronized with the CLOCK signal and the latch circuit 502
Will be output.

Table 2 shows the relationship between the number of pixels, the dot density, and the image size in the sublimation mode and the fusion mode.

The difference between the sublimation mode and the fusion mode is that the dot density of the sublimation mode is half that of the fusion mode, and this is based on the above-described difference in the gradation method. The number of pixels and the image size are the same, the number of pixels is about 370,000 pixels, and the image size is almost the size of a business card.

The thermal head 410 is composed of 496 heat-generating resistors, whereas Table 2 shows that the print data of one line of the captured image is composed of 494 pieces, and the print data for two pieces is insufficient. However, the serial output control unit 50
In the input of print data at 0, data without printing, for example, “00” is input for the two data.

Referring back to FIG. 21, the head driver 504 is composed of 496 NAND circuits, and print data output from each latch circuit of the latch circuit 503 is input to each NAND circuit. Also,
The 496 NAND circuits are divided into 8 blocks each of 62,
If the 1st to 62nd NAND circuit groups are the first block, the 63rd to 125th NAND circuit groups are the 2nd block, and the 435th to 496th NAND circuit groups are the 8th block, Control signals STB1 to STB8 are input to the respective NAND circuits. The output terminal of each NAND circuit is connected to one end of a heating resistor Ri (i = 1, 2,..., 496) of a corresponding dot, and the other end of the heating resistor Ri is always connected to a drive voltage ( For example
24v) is connected to the applied common terminal.

In the above configuration, for example, when a high control signal STB1 is input, a NAND signal of the control signal STB1 and print data is output to an output terminal of each NAND circuit in the first block, and 1
The 62nd print data is printed. In this case, only the output terminal of the NAND circuit to which the high print data is input becomes low level, the heating resistor Ri connected to the output terminal generates heat, and the dot is printed on the recording paper Pa.
Similarly, when the control signals STB2 to STB8 are input, the second to eighth
Each NAND circuit in the block operates, and print data is printed in block units.

FIG. 24 shows a time chart of the control signals STB1 to STB8. The control signals STB1 to STB8 are input in a time-division manner, and 62 print data are printed. In this case, the heating time of each heating resistor Ri of the heating unit 505 is controlled by the control signals STB1 to STB.
8 are controlled by the respective pulse widths T1 to T8.
8 determines the printing energy. Since the magnitude of the printing energy is proportional to the heat generation temperature of the thermal head 410, the temperature of the thermal head 410 is monitored by the thermistor 506, and the pulse width is controlled in accordance with a change in the temperature, whereby the printing energy is appropriately held. You. That is, the pulse widths T1 to T8 of the control signals STB1 to STB8 are shortened when the temperature rises, and lengthened when the temperature falls.

In the melting mode or the hand scan mode,
The gradation control is not performed depending on the magnitude of the printing energy, but in the sublimation type or gradation thermal mode, the gradation control is performed according to the magnitude of the printing energy.

The n-gradation control in the sublimation type or gradation thermal mode is performed by converting the image data of each dot into a gradation level and printing with a predetermined pulse width the number of times corresponding to the gradation level. That is, the image data of one line is converted into print data of n lines based on the gradation level data of each dot. For example, a dot having image data of k gradation levels is converted so that data with print is output for 1 to k lines and data without print is output for k + 1 to n lines. Then, on the same line, each of these print data is printed by control signals STB1 to STB8 having a pulse width corresponding to the print energy for one gradation. Therefore, the printing operation is performed n times in the same line. However, the image data of each dot is printed the number of times corresponding to the gradation level, for example, the dot having the image data of the k gradation level is printed only k times. Printing of image data according to the tone level is performed.

Next, the operation of the camera will be described with reference to the flowcharts of FIGS. First, the main flow will be described with reference to FIGS. 25 (A) and 25 (B).

And S ADJ are turned on in this order, and if any switch is on, switching to the mode or set value selected by that switch is performed. That is, if the switch S MODE is ON (YES in # 100), the shooting mode is switched to the set mode (# 130), and if the switch SFL is ON (YES in # 105), the flash The mode is switched to the set mode (# 135), and if switch S MONO is on (YES in # 110), the mode is switched to the binarization mode (# 14).

The date is changed to the set value (# 155), and the process returns to # 10. If any of the switches is in the off state in # 100 to # 125, it is determined whether 1 is set in the flag FCHG (# 160), and if FCHG = 0 (N in # 160)
O) Since the flash is not fired, the process immediately returns to step # 10. If FCHG is 1 in # 160 (YES in # 160), it is further determined whether the boosting (charging) of the main capacitor C is completed (# 165), and if the charging is completed (# 165 YES), returning to # 10, if the charging is not completed (NO in # 165), the boosting of the main capacitor C is started (# 175), and the process returns to # 10.
