Abstract

PURPOSE:To form plural punched holes in one straight line array by forming the punched holes in the state of being averagely dispersed by the sheet material punching action of plural ordered punches in relation to the sheet material surface area along the array of the punches. CONSTITUTION:Two punches 1', 1' among plural punches are first put in sheet material punching-action to come in contact with sheet material 2 at two points, thus suppressing the separation of the sheet material 2. The punch 2' at the center is then put in sheet material punching action, and then the center punch 3' between the punch 1' and the punch 2' is put in sheet material punching action. The punches are thus put successively in sheet material punching action. Punched holes are thereby formed being averagely dispersed, and the formation of a specified number of punched holes is finally completed by the termination of sheet material punching action of all the punches. The edge of the sheet material is sunk, and the opposite side is lifted, but since the deformation of the sheet material 2 can be made two-dimensional on the whole, a specified number of punched holes formed in the sheet material 2 are arrayed in a straight line.

Referring to FIG. 6, when the rack 71 is lowered by the motor 59 via the gear train 57 shown in FIG. 6, the drive plate 70 is guided by the guide plate 63 and descends.

Then, the slanted projection 67 of the drive plate 70 is replaced by the slanted groove 66.
The component force to the right in FIG. 21 is applied to the lower claw 56 via. Then, the projections 65 of the lower claw 56 are aligned with the grooves 6 of the guide plate 63.
2 is moved to the right by being guided to the horizontal part of the ring 6 and brought into a state where it can be engaged with the finger part of the ring 6, and then is guided to the vertical part of the groove 62 by the component force of the lower part, so that the lower pawl 56 is moved. It descends and opens the fingers of the ring 6 downward. The rack 71 moves the motor 5 upwards.
When pressed by 9, the lower claw 56 moves in the opposite manner to the above.
The pressing plate 72 is integrated with the drive plate 70 via the screw 75 and always holds the lower claw 56. For this reason, the screw 75 moves in the same manner as the slanted protrusion 67, and therefore the beveled hole 73 similar to the light shield 66 is provided in the lower claw 56.

In the above-described embodiment, the sheet material 2 that has been bound is pulled out manually in the direction opposite to the conveying direction. However, when the sheet materials 2 have been bound, the upper feeding roller 40b is turned on by the solenoid 47. Without turning off
When the binding completion display is displayed on the display unit 85,
The motor 8 that drives the transport rollers 40a and 40b may be reversed to automatically pull out the bound sheet material 2.

By doing so, labor saving and time saving of the binding work can be improved.

E. Manual Mode Next, the operation of the manual mode will be described. As shown in FIG. 23, when the main body 7a is tilted about the pin 76 and fixed, an ON signal of the microswitch 77 is issued, and the control unit 85 receiving this signal switches the control system to the manual mode.

Then, the auxiliary guide 79 rotates clockwise around the pin 79a, and the sheet material 2 in the manual mode is rotated.
Support and guide. In this mode, if the punching ability of the punch 17 or the like is insufficient with respect to the stitching ability of the ring 6, punching is performed many times and additional stitching is required. There is also a case where it is desired to perform replacement, etc., and this mode is used when there is inconvenience only in the automatic mode.

Since the sheet material 2 is not automatically conveyed in the manual mode, the ring 6 is opened and closed by operating the ring opening button 82 and the ring closing button 83 shown in FIG.
The amount of opening is determined by the operator. The opening amount for the ring 6 is memorized by the control unit 85 as in the case of the automatic mode.
Therefore, the opening amount of the ring 6 may be obtained by pushing the optimum number of times (if the ring opening button 82 is pushed too much, the opening amount does not become larger than the amount learned by the device).

When the work is finished, the ring closing button 83 is pushed to perform the closing operation and the work is finished.

When it is desired to add or replace the sheet material 2, as shown in (a) of FIG. 24, when the sheet material 2 is set under the upper claw 52 and the ring opening button is operated, as shown in (b), The sheet material 2 can be freely removed, and the sheet material 2 can be freely added or replaced.

By tilting the main body 7a, the visibility can be improved and the usability can be further expanded.
