(11) Turn on the main switch 27 to remove the base paper, input the DC II [source voltage] from the terminal 27' to the differentiator circuit 28 as shown at 27' in FIG. The H level signal generated at the rising edge of
(4 points of Sl in Fig. 5), and as shown in Fig. 5, an H level signal is simultaneously output from its output terminal Q. This H level signal is input to the control circuit. 32 input terminal 33, the motor 11 rotates the drum 1.2 at a very low speed. Then, as the drum 1.2 rotates, the screen 4 rotates and moves to a predetermined position where the base paper can be easily removed. The position detecting device iI [10 outputs an H level position detecting device (point B of 10' in FIG. 5) via the input terminal 10', and this signal is sent to the differentiating circuit 34 to reset the flip-flop 24. 0 input to terminal R1 This input resets the 7th lip-flop 24 to
As shown at point B in the figure, an L-level signal is output from the output terminal Q, and this L-level signal is input to the input terminal 33 of the control circuit 32 to drive the motor 11, that is, the drum L.

The screen 4 attached to the screen 2 stops at a predetermined position.

When the screen 4 has stopped at a predetermined position, remove the edge of the base paper P on the screen 4, hold it by hand, and turn on the base paper removal switch 2G (Fig. 83).

On the other hand, the input terminal S of 2 7 Ritsuzo flops.

, the input terminal 29' is connected by the base paper removal switch 29.
An H level input signal generated at is input, and an H level signal (point 0 in FIG. 5) is already output from the output terminal Q, and this H level signal is input to one input of the quand circuit 22. Since it is input to one input terminal of the AND circuit 20 via the terminal and the OR circuit 19, the output terminal 4. At the same time, an H level signal is output from the output terminal of the AND circuit 20 as shown at point D at 43 in FIG. are respectively input to the other input terminal.

Due to the input to the input layer 43, the drum 1゜2#'i shifts from ultra-low speed - rotation to low speed 1 rotation and continues to rotate (B), and at the same time, an H level signal is sent from the output terminal of the AND circuit 22. The output is output to operate the ink supply device i7 to dispense ink. When the screen 4 rotates several times due to the simultaneous rotation of the drum 1.2, the ink spreads over the screen 4, and the base paper P tends to come into close contact with the screen 4.

In this way, every time the screen 4 moves once, the fifth
As shown between D-8 in the figure, an H level position detection signal is output, and this signal is input to one input terminal of the AND circuit 21. The other input terminal of the AND circuit 21 receives the D output from the AND circuit 20 as shown in FIG.
Since the continuous H level signals shown between -8 and 8 are input, the 1 position detection signal is input to the counter 44 each time it is output.Then, this counter 44 counts the number of position detection signals and sets it in advance. When the predetermined number N is reached, the counter 44 outputs an H level C as shown in FIG.
1m) signal is output, and this H level signal is input to the input terminal R3 of the 7-lip flop 25, and the flip-flop
Reset flop 25 0 Output terminal Q8 of reset flip-flop 25
An L level signal (w, point E in Figure 5) is output from
At the same time, an L level signal is output from the AND circuit 20 and input to the input terminal 43 of the control circuit 27 to stop the screen 4 at a predetermined position.

(3) To attach the atom, attach the edge of the new base paper to the hanger 5, and turn on the switch 30 to attach the base paper.
As shown in FIG. 5, an H level input signal is generated at point F through the OR circuit 18, and this signal is input to the input terminal S1 of the flip-flop 24, and at the same time, the input signal is input to the input terminal S1 of the flip-flop 24. This H level signal is input to the input terminal 33 of the control circuit 32 to move the drum 1.2, that is, the screen 4, one rotation at a very low speed. When the above-mentioned new base paper is deposited on the screen 4, the screen 4 moves one rotation, and the drum 1.2 shifts from ultra-low speed rotation to low speed (rotation) and rotates the screen 4 in the same way as in (2). It is rotated by the number of times set in the counter 44 and stopped at a predetermined position.

When removing the mount and attaching the base paper, if there is a mount on the base paper, (
During the rotational movement of the screen 4 in step 3), the input terminal 9 is detected by the reflected light from the mount detection device 9 as shown at point G in Figure 5.
The H level mount detection signal is outputted through the AND circuit 23 and inputted to the input terminal 47 of the AND circuit 23. Continuous H between the output terminal of and points G-J
Level output signal G, 717 Tuzo flop 26th output terminal Q.

Since a continuous H level output signal is input from the output terminal of the AND circuit 23 to the point G-
The H level signal of J and the following is output, press roller pressure bonding waves 1 and 8 are activated, and press roller 6 is moved to drum l.
At the same time as the rotation of the drums 1 and 2 stops, the H level output signal output from the output terminal of the AND circuit 23 changes to an L level signal at one point, and the press The pressure of the roller 6 on the drum 1 is released. When the screen 4 has stopped at a predetermined position, peel off the perforation at the leading end of the mount attached to the base paper and press the mount removal switch 31.

As a result, an H level input signal is generated at point i through the input terminal 31' as shown in FIG. (Similar to step 11, rotate the drum 1 at a very low speed, rotate the screen 4 at a speed that makes it easy to remove the mount, and remove the mount.

When the screen 4 rotates once, an H level position detection signal is output from the input terminal 10' at point M as shown in FIG. Input in R8 (1
), the rotation of the drum 1 is stopped and the screen 4 is stopped at a predetermined position.

Since this invention is as described above, it has the following effects. By stopping in response to a signal from the position detection device, then holding the base paper by hand and turning on the base paper removal switch, the base paper can be removed while moving the screen again at an extremely low speed, and the base paper can be removed by grasping the base paper. The screen is always in a fixed position, and the removal work is done while moving at extremely low speeds, so the removal can be done safely and smoothly. While moving, ink is dispensed by the ink supply device, and in this way, the screen rotates a predetermined amount of time, automatically spreading ink evenly over the screen and improving the adhesion of the base paper. be able to.

(3) When attempting to attach the base paper after this,
゛For installation, attach the base paper tabs to the hanger of the screen that is stopped at a certain position that is convenient for work, and then turn on the switch to attach the base paper, but in this case, the process is exactly the same as when removing it. Since this is done when the screen is moved from a fixed position, the work can be done safely and smoothly.

(4) When the backing paper is attached to the base paper during this installation, the screen is rotated at a very low speed by turning on the switch as described above, and after the l[g1 rotation, the screen is rotated at a predetermined number of times. The press roller crimping device is activated by the signal output from the mount detection device to perform printing, and then when the screen is stopped at a certain position, hold the mount by hand and turn on the mount removal switch.
Because the mount is removed at extremely low speeds in exactly the same way as when removing the base paper, the work can be done safely and smoothly.
