On the other hand, on the shaft of the main motor 51, on the opposite side from the motor gear 52, a clock disk 67 having a plurality of slits arranged at equal intervals on the circumference is fixed.
A clock sensor 68 consisting of a transmission type optical sensor for detecting the slit is provided near the slit.

Next, a description will be given of the operation when the laminating apparatus C according to the present invention laminates the transfer paper lO discharged from the main body of the image forming apparatus.

First, the operation section 17 arranged on the top surface of the laminating apparatus C
When the lamination ON switch is pressed, a solenoid (not shown) is turned on and the flapper 16 becomes the state shown in the solid line in FIG. At the same time, the main motor 51 starts rotating, thereby causing the paper discharge roller 19 to rotate. still.

Registration roller 22. Pressure roller 30. Pull roller 36
and the laminate paper discharge roller 37 is connected to the clutches 64, 65.
59 are in the OFF state, so they are stopped.

Then, when the leading edge of the transfer paper lO is detected by the pre-registration sensor 23, the clock sensor 68 starts counting the number of clocks.

When the leading edge of the transfer paper lO reaches the nip position between the registration rollers 22, 22°, and the clock sensor 68 generates a clock corresponding to ensuring a predetermined loop amount, the registration roller clutch 64 is turned ONL.
Transfer paper 10 begins to be transferred to transfer bus 24 by registration rollers 22, 22°. At this time, the loop of the transfer paper IO formed in the laminating path 21 is held by the rear end force of the transfer paper IO (until it comes out of the paper ejection roller 14 of the printer B. Pressure roller 30 of laminate heater 29, 29' from nip position,
30', the leading edge of the transfer paper 10 in the transfer path 24 is the pressure roller 30, 30'.
When it is detected by the count of the clock sensor 68 that the position in the transfer bus 24 has been reached by a sentence plus α from the nip position, the pressure roller clutch 63 is turned on.
Then, the pressure rollers 30, 30' begin to rotate.

It should be noted that the fact that the leading edge of the transfer paper 1O has reached a position that is + α further from the nip position of the pressure roller 30, 30° means that the leading edge of the transfer paper 10 has reached the position of the registration roller 22, 22° from the nip position of the pressure roller +30, 30°. Since the distance to the nip position is predetermined, detection is performed by subtracting the distance plus α from the distance and calculating the distance by clock counting by the clock sensor 68 from the time when the registration rollers 22, 22° rotation starts. be done. As a result, the leading edge of the transfer paper 10 is positioned at a position shifted backward by α from the leading edge of the heated portion of the lamination heater 29, 29', and the leading edge of the transfer paper 10 is reliably laminated.

Thus, the heated upper and lower laminate films 28.2
The transfer paper lO is sandwiched between the transfer paper sheets 8' and fed into the nip between the pressure rollers 30 and 30', and is laminated by being pressed by the pressure rollers 30 and 30[deg.]. When the leading edge of the transfer paper 10 laminated in this way is detected by the lamination sensor 32, the registration roller clutch 64 and the pressure roller clutch 63 are simultaneously set to 0FFL/, the transfer of the transfer paper 10 is stopped, and at the same time, the cutter unit The cutter motor (not shown) in 33 is turned ONL/, and the cutter blade 34 is pushed down to cut the leading edge of the laminated transfer paper IO. After the cutter blade 34 finishes cutting and is completely retracted upward, the registration roller clutch 64. Pressure roller clutch 63 and pull roller clutch 59 are 0/N.
L/, registration rollers 22, 22', pressure roller 30
30°, the pull rollers 36 and 36° start rotating, respectively.

When the rear end of the transfer paper 1O is detected by the pre-registration sensor 23, the registration roller clutch 6 is activated when the rear end of the transfer paper 1O passes through the nip between the registration rollers 22, 22°.
4 is 0FFL/, and the rotation of the registration rollers 22, 22° is stopped. The clock sensor 68 also measures the amount of movement from when the pre-registration sensor 23 detects the rear end of the transfer paper 10 until the rear end of the transfer paper 10 passes through the nip position of the registration rollers 22, 22°. When the rear end of the transfer paper lO after lamination processing is detected by the lamination sensor 32, the distance from the lamination sensor 32 to the cutter 33 is measured by the clock sensor 68, and then the pressure roller clutch 63 and the pull roller clutch 59 are
is turned off, and the transfer of the transfer paper 10 after lamination processing is stopped. At the same time, the cutter motor is turned on,
Transfer paper lO after lamination processing by cutter blade 34
The rear end of is cut. After cutting, pull roller clutch 59
is turned on, the pull roller 36 and the laminating paper ejecting roller 37 begin to rotate, and the laminated transfer paper 10 is ejected and stacked onto the laminating tray 38.

By repeating the above series of operations, the lamination process is performed on the transfer sheets 10 that are successively discharged from one image forming apparatus main body.

Next, control of the rotational speed of the main motor 51 will be explained.

When the transfer paper 10 is laminated, the higher the density of the transfer paper 10, the greater the amount of heat absorbed by the transfer paper 10. Therefore, when heating the laminate films 28, 28' with the laminate heaters 29, 29' under the same conditions, in order to perform a good lamination process, the conveyance speed of the laminate films 28, 28' and the transfer paper 10 should be slowed down. setting (that is, slowing down the rotational speed of the main motor 51). In other words, the pressure roller 30.30°
The laminate film 28 is absorbed by the transfer paper lO at the
．． Laminate heater 29.29' considering the heat of 28°
Transfer paper l by applying the heat in the section
It is necessary to increase the amount of heat absorbed by O.

Further, as the thickness of the transfer paper 10 increases, the amount of heat absorbed by the transfer paper 10 increases as described above, so the conveyance speed of the laminate film 28, 28' and the transfer paper 10 must be set to be slow.

Furthermore, as the thickness of the laminate film 28.28' increases, the amount of heat absorbed by the laminate film 28.28° increases, so similarly, the transport speed of the laminate film 28.28° and the transfer paper 10 must be set slowly. Must be.

Therefore, in the laminating apparatus C according to the present invention, the image density and thickness of the transfer paper 10, the laminating film 28
．． The conveyance speed of the transfer paper lO and the laminate film 28.28° is controlled according to the change in thickness of 28°,
Data from the density detection sensor 26, paper thickness detection sensor 43, and core identification switch 46 can be fed back to the rotational speed of the main motor 51.

Next, 0N10FF and temperature control of the transfer paper heater 25 will be explained.

After the image is formed with ink in the image forming device 9
Ink adheres to the surface of the transfer paper 10 output from the image forming apparatus main body, and the transfer paper 10 is discharged in a wet state. For this reason, the transfer paper should be kept wet.
When lamination is applied to the film, moisture is sealed between the upper and lower laminate films 28, 28', and air bubbles are generated, which deteriorates the quality of the lamination process.

Therefore, before the lamination process, the transfer paper lO is heated in advance.
Is it necessary to evaporate the moisture in the transfer paper IO?

However, if the transfer paper is heated more than necessary,
Curling occurs in the O, and this curling causes troubles such as wrinkles and curling during lamination processing. The degree of wetness of the transfer paper 10 changes depending on the image density, and the higher the density of one image, the worse it becomes for laminating processing.

Therefore, in the laminating apparatus C 3 according to the present invention, the image density is detected in advance by the density detection sensor 26, and the heating temperature can be automatically controlled based on this result. That is, if the image density is high, the heater temperature is set high, and if the image density is low, the heater temperature is set low. Note that some image forming devices do not use ink and form images using toner, etc.
In such an image forming apparatus, since the transfer paper is discharged in a dry state, heating before lamination processing is not necessary. Therefore, the user can turn off the transfer paper heater heating switch provided in the operation section 17.

Next, temperature control of the laminate heaters 29 and 29° will be explained.

Similar to the rotation speed control of the main motor 51 described above, the amount of heat absorbed by heating the laminate film 28.28° changes depending on the image density of the transfer paper 10, the thickness of the transfer paper IO and the laminate film 28.28'. Therefore, it is necessary to control the temperature of the laminate heater 29.29° accordingly. In other words, the higher the image density, the thicker the transfer paper 1O, and the thicker the laminate film 28.28°, the more the laminate heater 2
It is necessary to raise the temperature at 9.29°.

Accordingly, in the laminating apparatus C according to the present invention, each data from the density detection sensor 262, paper thickness detection sensor 43, and core metal identification switch 46 can be fed back to the temperature control of the laminate heater 29, 29'. It has become so.

Next, the above control and operation will be explained based on the block diagram shown in FIG.

FIG. 5 is a block diagram showing a control circuit for performing the operations described above, and the control circuit is mainly composed of a well-known one-chip microcomputer (hereinafter referred to as MC0M) 70 that has built-in ROM, RAM, etc. The input ports P o to P7 of this MC-0M70 each have the above-mentioned laminate/non-laminate switch.
