Electrical components such as fuses 37, wiring and power cords are installed inside either one of the two-way bars 12-120, and the switch 34-36 and the switch 35a of the switch 17-35 are connected to the cover 12. The upper wall 12e of the upper wall 12e is supported in an exposed manner.

Further, the movable frame 4 is slidably supported between the support plates 11, 11 of the main body frame 1, and the support plates 1. ．． ．． A pair of elongated holes 11f extending in the horizontal direction are formed in the back wall 11c of 1, , , 1.1.

11f, a pair of bolts 43 fixed to the movable frame 4
It penetrates and supports it.

That is, as shown in FIG. 4, a bearing sleeve 45 is attached to the bolt 43 via a pair of receiving pieces 41 and 42 and a collar 44.
... is interposed, and the bolt 43 ... is provided with a nut 1.
-4b... is screwed in, and by tightening this nut 46..., the back wall 1 of the support plate 11 is inserted between the receiving pieces 41, 42.
1c, the movable frame 4 is attached to the main body frame 10 and support plates 11. ．． It is slidably supported between 11.

In addition, a plurality of cutout windows 47 are formed on the opposite wall of the movable frame 4 facing the receiving plate 2, and a comb-like push plate 5 is formed under the push plate 5. An L crosspiece plate 51 is fixed to the edge, and a plurality of punched locking pieces 52 formed on the L crosspiece plate 51 are removably inserted into the cut window 47. The push plate 5 is attached to the movable frame 4 so as to face the receiving plate 2.

Further, the movable frame 4 is provided with a locking device 6 for fixing its slide.

As shown in FIG. 5, this locking device 6 includes two push rods 61, 61 each having a rubber braking piece 62, 62 at one end, a knob body 63 having a support shaft 64, and an eccentric cam portion. It consists of two cam plates 65 and 65, and both push rods 61
61 along the inner surface of the front wall of the movable frame 4, and the outer parts of the push rods 61, 61 are fixed to the inside of the movable frame 4 through the cutout holes 49 of the support plates 48, 48. 49 to support the respective outer parts of the press rods 61 and 61, and loosely fit the cam portions of the cam plates 65 and 65 into the holes formed at the inner ends of the press rods 61 and 61, respectively. But this cam plate 65
．． The support shaft 64 of the knob 63 is inserted into the knob 65 so as not to rotate relatively, and on the circumferential surface of the eccentric cam portion of the cam plate 65.65,
The base end surfaces of the pushing bodies 61, 61 are brought into contact with each other, and if the knob body 63 is rotated to one side by this,
The push rods 61, 61 are pushed outward via the cam plates 65, 65, and the braking pieces 62, 62 are brought into pressure contact with the support plates 11, 11 of the main body frame 1, and the movable frame 4 is pushed out. When the slide is locked and the knob 63 is rotated to the other side, the push rods 61, 61 are pulled inward and the lock of the movable frame 40 is released.

The bookbinding machine of the present invention is constructed as described above, and when binding a book, a hot melt sheet of a predetermined width with a pressure-sensitive adhesive coated on the negative side is temporarily adhered to the inside of the spine of the cover (not shown).
Next, a group of sheets to be bound is inserted between the inner sides of the front cover and the back cover of the cover and twisted, so that one side edge of this group of sheets is brought into contact with the hot melt sheet.

- On the second-hand book machine side, turn on the main switch 34 of the heater 3, place the heating plate 31 in place using the heater 3, slide the movable frame 4 in the open position, and stop the push plate 5 at an arbitrary position. , insert the cover and the sheet group between the receiving plate 2 and the push plate 5 with both hands, place the spine of this cover on the heating plate 31, and then slide the movable frame 4. , the paper sheets are held between the receiving plate 2 and the pressing plate 5 together with the cover with an appropriate pressing force, and the locking device 6 prevents the movable frame 4 from sliding, and then the timer 35 is activated. It is set at a predetermined time and the heater 3 heats the spine of the cover for a predetermined time.

As a result, the hot melt sheet is melted, one side edge of the paper sheet is adhered to each other, and the side edge is adhered to the inside of the spine, and the paper sheet is stacked in the cover. Then, the book is bound.

As explained above, the bookbinding machine according to the present invention forms a main body frame with a pair of opposing support plates on both sides,
A housing-shaped cover is attached to the outside of both support plates of this main body frame, and a movable frame body having a push plate is slidably supported between both support plates, and both support plates A receiving plate facing the pushing plate is provided substantially vertically on the main body frame located between the two, and the sheet of paper is held between the receiving plate and the pushing plate by sliding the movable frame. A heating plate with a heater is supported between the support plates of the main body frame below the movable frame, and the electrical components of the heater are installed in either one of the double force bars, while the movable frame A knob body is rotatably provided on the body via a support shaft having an eccentric cam portion, and a push piece having a brake piece at the tip is slidably held in the length direction thereof, and the push piece is The base side end surface is brought into contact with the circumferential surface of the eccentric cam part, and the rotation of the knob causes the push rod to advance outward via the eccentric cam part, and the brake piece is pressed against the support plate. Since the movable frame body is designed to prevent sliding, all electrical components of the heater can be supported by the cover, and the cover can be attached to and removed from the support plate. In other words, since the electrical components of the heater are mounted on the main body frame and within a removable cover, it is extremely easy to install and remove the electrical components and perform maintenance and inspection. There is no need for a special cover to protect the parts, the structure is simple, costs can be reduced, and damage and failure of electrical parts can be eliminated.

Since a locking device is provided to prevent the movable frame from sliding, when binding a book, the movable member is slid in advance to stop the push plate at an arbitrary position, and the cover and the sheet group are moved between the receiving plate and the receiving plate using both hands. The spine of the cover can be easily placed on the heating plate by inserting it between the receiving plate and the pressing plate, and then the movable frame is slid and the sheet group and the cover are inserted between the receiving plate and the pressing plate. The movable frame body can be prevented from sliding by the locking device, and therefore, one side edge of the group of paper sheets made of hot melt sheet and the spine of the side edge can be prevented from sliding. This eliminates the misalignment of the paper sheets during each welding process to the inside, as well as the misalignment of the cover relative to the paper sheets, making it possible to accurately bind the book.
