Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a facsimile machine, which is used, for example, in photographic transmission, and records thermal transfer onto recording paper by heating heat-melting ink coated on a transfer film with a thermal head. Regarding equipment.

[Technical background of the invention and its problems] A transfer film coated with heat-melting ink and a recording paper are overlapped, and the ink coated on the transfer film is heated by a heating element such as a thermal head. Facsimile machines that use the thermal transfer recording method, which transfers images to recording paper by melting ink, can use inexpensive paper, and images recorded on regular paper can be stored for a long time. There are advantages. Furthermore, this method has the advantage that color recording can also be performed.

By the way, in a facsimile machine using such a thermal transfer recording method, in order to overlap the transfer film and recording paper and move them between the thermal head and the platen, a drive transmission system using a motor and a gear 1b belt is used. By the way, if a facsimile machine having such a drive transmission mechanism receives an incoming call via a telephone line, and the facsimile machine is activated by this incoming signal, the drive transmission f1 Normally, the printer is in a stopped state, but even if you try to start the drive transmission mechanism in this stopped state to move the transfer film and recording paper,
Although the drive transmission mechanism starts up from a stationary state, there is a delay due to its inertia and play, and the transfer film and recording paper cannot be moved immediately.

On the other hand, as mentioned above, when a facsimile machine receives an incoming call and starts up, in conventional devices, the thermal head can be energized immediately depending on the recorded information; Particularly in the case of photographic transmission, for example, when the recording starts in black or colored information, this information causes the facsimile machine to be heated at the same time as it is activated, and to melt the ink applied to the transfer film. However, in this case, although the transfer film and the recording paper cannot start moving yet due to the delay in the drive transmission mechanism described above, the thermal head is immediately controlled to be energized, and the information to be recorded is printed in black. Alternatively, in the case of a colored image, this information causes the thermal head to heat the same portion of the immovable transfer film, for example, twice or more in succession. As a result, the portions of the transfer film that are continuously heated by the thermal head melt and adhere to the thermal head, making it impossible to perform subsequent thermal transfer recording operations.

Conventionally, in order to solve the above problem, the drive was transmitted to the rental structure.
A method of reducing the delay due to inertia of the drive transmission mechanism using a motor, detecting the information to be recorded, and controlling the voltage applied to the thermal/rad or its pulse width according to this information. However, the method of using two motors is expensive, and the method of detecting recorded information and controlling the voltage applied to one thermal head or its pulse width requires a circuit with multiple watts. There was a problem.

[Object of the Invention] The present invention has been made in view of the above, and its purpose is to provide a facsimile device that can prevent a transfer film from being welded to a thermal head and can accurately perform thermal transfer recording. It's about doing.

[Summary of the Invention] In order to achieve the above object, the present invention superimposes a transfer film coated with a heat-melting ink and a recording paper and moves between a heating head and a platen. In a facsimile machine that heats the transfer film to melt the ink applied to the transfer film and record recorded information on recording paper by thermal transfer,
The gist of the present invention is to include information delay control means that starts energizing the heating head based on recording information after a predetermined delay time after the transfer film and the recording paper start moving.

[Effects of the Invention] According to the present invention, after a predetermined delay time has elapsed after the driving of the moving means for moving the transfer film and the recording paper is started, energization is started to heat the heating head. Since the heater is heated at the same time as when the transfer film and recording paper start to move, the same area of the transfer film is not heated overlappingly, which prevents the transfer film from melting and welding to the head. This makes it possible to perform thermal transfer recording accurately.

[Embodiments of the invention] Hereinafter, the present invention will be explained in detail using the drawings.

A roll-shaped transfer film 29 is attached to 7. As shown in FIG. 2, one end of the transfer film 29 passes between the platen 9 and the thermal head 13 via a guide bar 31, and then passes through another guide bar disposed above the platen 9. 33 and 35 and further passes the tension bar 37, the transfer film is fixed to a transfer film winding core 39 and wound up. The tension bar 37 allows the transfer film 29 wound around the transfer film winding roll 27 to pass through the guide bar 33, 35 between the guide bar 31, the platen 9 and the thermal head 13, and to be wound around the transfer film winding core 39. Transfer film 2 while being removed
Appropriate tension is applied to the transfer film 29 to prevent the transfer film 29 from becoming loose or wrinkles from being formed on the transfer film 29.

A pulley 7 coaxially attached to the platen 9
A belt 41 constituting a second drive transmission mechanism is further hung on the belt 41 . This belt 41 is also hung around the support shafts 19a and 23a of the paper feed rollers 19 and 23, respectively, and when the pulley 7 rotates as described above due to the rotation of the motor 3, the paper feed roller 19 and 23 is designed to rotate. Also, pulley 7
is provided coaxially and integrally with the gear 43, and another gear 45 meshes with this gear 43. Also, this gear 4
A belt 47 is hooked between the support shaft 45a of No. 5 and the transfer film take-up core 39, and when the platen 9 is rotated by the motor 3 as described above, the gear 43° constituting the third drive transmission mechanism 45, the transfer film winding core 39 is rotated in the direction shown by the arrow via the belt 47.

The transcription is performed.

FIG. 3 is a block diagram of a control section that controls the operation of the hook/cutter device shown in FIGS. 1 and 2. FIG. In the figure, a recording signal generating section 51 is activated by an incoming call signal when the facsimile machine receives an incoming call via a telephone line, and receives a recording start signal S.
S is output to the motor drive unit 53 and the recording information signal 3i is output to the delay circuit 61. As a result, the motor drive unit 53
supplies an operating voltage to the motor 3 and starts rotating the motor. The rotation of this motor drives the platen driving section 55, which includes the belt 5, pulley 7, etc. described above, and rotates the platen 9. Further, the rotation of the pulley 7 of the platen drive unit 55 is controlled by the platen 9, the belt 41, and the paper feed roller 1.
When the recording paper 18 is sent out from the recording paper winding roll 15 by driving the group feed roller drive unit 57 consisting of gears 43, 45, belt 47, transfer film winding core 39, etc. The transfer film 29 is pulled out from the transfer film winding roll 27 by driving the five core drive units. On the other hand, the recording information signal S1 supplied to the delay circuit 61 is delayed to account for mechanical delays caused by inertia and play in the motor 3, platen drive unit 55, paper feed roller drive unit 57, and winding core drive unit 59. After time Td, a delay signal Sd is output from the delay circuit 61. This signal drives the thermal head energizing section 63, and the energizing signal is supplied from the thermal head energizing section 63 to the heating element 49 of the thermal head 13. ing.

Next, the operation of the facsimile machine configured as described above will be explained with reference to the timing chart of FIG.

First, when this facsimile machine receives an incoming call via a telephone line, for example, the incoming signal activates the recording signal generating section 51, and sends a recording start signal SS to the motor driving section 53.
and outputs the recording information signal S1 to the delay circuit 61. The recording start signal SS drives the motor drive section 53 to supply an operating voltage to the motor 3 and start the motor 3. The motor 3 cannot rotate immediately due to its mechanical delay, but starts rotating after a slight startup delay time, as shown by the motor rotation signal 5IIl in FIG. When the motor 3 starts rotating, this rotation drives the platen drive section 55, and the platen 9 moves through the belt 5 and pulley 7 as indicated by the arrow 11 after a slight delay as shown by platen rotation No. 13 Sp in FIG. Rotate in the direction shown.

When the platen 9 starts rotating, this rotation drives the paper feed roller drive unit 57 and the five winding core drive units.

The paper feed roller drive section 57 and the take-up core drive section 5 start operating after a slight delay as shown in the paper feed operation signal 3r and take-up core operation signal SC in FIG. 4 via the above-mentioned components, respectively. Then, the operation of feeding out the recording paper 18 and the transfer film 29 is started.

More specifically, when the heptad 3 is activated by the recording start signal Q3s and rotates after a slight delay, the pulley 7 rotates via the belt 5. When pulley 7 rotates, platen 9 rotates in the direction of arrow 11, and paper feed rollers 19 and 23 rotate clockwise in FIG. 2 via belt 41. As a result, the recording paper 18 held in pressure contact between the rotating paper feed roller 19 and the driven roller 21, between the platen and the thermal head 13, and between the paper feed roller 23 and the driven roller 25 is The recording paper is pulled out from the winding roll 15 and begins to move so as to be sent out from between the paper feed roller 23 and the driven roller 25 to the outside of the apparatus. Further, as described above, when the pulley 7 rotates and the platen 9 rotates, the gear 43 coaxially and integrally attached to the pulley 7 similarly rotates in the direction of the arrow 11 and meshes with the gear 43. The gear 45 shown in FIG. 2 rotates counterclockwise in FIG. As a result, gear 4
The three transfer film winding cores are rotated in the direction of the arrow via the belt 47 that is hung on the support shaft 45a of No. 5. As a result, the transfer film 29 attached to the transfer film winding roll 27 is transferred to the three transfer film winding cores via the guide bar 31, between the platen and the thermal head 13, the guide bar 33, 35, and the tension bar 37. The transfer film is pulled out from the transfer film winding roll 27 and begins to move so as to be wound around the transfer film winding core 39.

On the other hand, the recording information signal g3i from the recording signal generating section 51 is
The signal is supplied to the delay circuit 61, and output as delay No. 18 Sd after a predetermined delay time Td shown in FIG. 4 has elapsed. This delay time Td is determined by the recording signal generation section 51 as described above.
From when the motor drive section 53 is driven until the paper feed roller drive section 57 and the five take-up core drive sections start operating, that is, from when voltage is applied to the motor 3, the recording paper 18 and the two transfer films start moving. The delay time due to the inertia and play of the surrounding parts (such as motors, belts, pulleys, platens, gears, etc.) is set to correspond to the delay time due to play. When this i-time delay signal 3d is output from the delay circuit 61, the thermal head energizing section 63 is driven by this signal, and the heating element 49 of the thermal head 13 is driven by the energizing signal sh from the thermal head energizing section 63. heated. This heating melts the heat-melting ink applied to the transfer film 29, and the image is transferred to the recording paper 18. Therefore, the timing when this heating element 49 starts to heat up is exactly when the paper feed
- Since this is the time when the roller drive section 57 and the winding core drive section 59 start operating and the recording paper 18 and the transfer film 29 start moving, the same part of the transfer film 29 is connected to the heating element 4.
Since the two transfer films are not heated together due to the heating in step 9, the two transfer films are melted and transferred to the thermal head 1 as in the conventional case.
3 will not be welded. In this way, the four heating elements of the thermal head 13 are energized, and the rotation of the motor 3 is completely transmitted to each drive transmission mechanism, so that the recording paper 18 and the transfer film 29 are transferred to the recording paper winding roll 15 and the transfer film 29, respectively. After the film begins to be fed out from the film winding roll 27, it operates normally like a normal device.
