Then, the drive motor is stopped where the position between the fixed holding member 41 and the movable holding member 42 of the tape winding means 40 is near the tape supply end 130.

The one roller 133 of the tape path 131 of the tape supply end 130 is driven to rotate in the reverse direction until the leading end of the cut tape T is detected by the third tape detecting means 135B. Once detected, it is stopped once.

At the same time, the iron 96 retreats, and the cam member 23 moves downward in FIG.
4 follows, the main holding members 8 and 9 are separated from each other to release the holding of the sheet P, and the slide member 31 is moved in FIG.
In FIG. 5, the lever 28 is pushed back by the protrusion 36 to rotate the sub-clamping member 11 and the roller 39 falls from the raised portion 37 of the slide member 31, so that the sub-clamping member 10 falls backward.

As a result, the bound sheets P are completely released, and the bound sheets P can be taken out by pulling the sheets P forward or upward.

When the sheet P is taken out, each of the sensors 136, 136, and 138 detects the absence of the sheet, whereby the one roller 133 of the tape path 131 is driven to rotate forward, and the tape T is rotated. The tape is fed between the fixed pinching member 41 and the movable pinching member 42 of the tape winding means 40 waiting near the leading end of the tape path 131 of the tape supply end 130. Thereafter, the tape winding means 40 is rotated counterclockwise when a predetermined amount of the tape T is delivered after the tape T is detected by the third tape detecting means 135B in the tape path 131. . At this time, the cam follower member 48 at the base of the movable holding member 42 of the tape winding means 40 is provided with the cam body 50 provided on the machine frame 49 side.
The movable holding member 42 is closed by the bias of the spring 47, and the tape T is sandwiched between the fixed holding member 41 and the movable holding member 42 of the tape winding means 40. Then, the tape winding means 40 is stopped on the side opposite to the tape supply end 130, and the tape T
However, the driving of one roller 133 of the tape path 131 is stopped in a loop state surrounding the binding position A of the paper sheet P, and the apparatus enters a standby state for inserting the next paper sheet P (FIG. 1).
6).

The specific structure including the tape winding means 40 is not limited to the illustrated embodiment, and any design change may be made without departing from the technical concept of the present invention.

As described above, according to the present invention, the front and rear portions of the binding position of the paper sheets to be inserted from the paper sheet insertion opening are held by the pair of holding members. Since it is bound with tape in the part between
While the stacking state of the paper sheets is not disturbed and can be tied up, one of the pair of holding members retreats and moves out of the orbit where the holding member of the tape winding means rotates, so that an obstacle at the time of winding the tape is obstructed. Therefore, the space inside the device body can be used without waste, the device itself can be made extremely small, and it can be placed anywhere and can be used easily without taking up installation space as a manual binding device. Excellent effects can be obtained.
