Next, the recording means will be described.

The recording means records an ink image on the recording sheet conveyed by the conveying means. An inkjet recording method is preferably used as the recording means in this apparatus.

The ink jet recording system is provided with a liquid ejection port for ejecting and ejecting a recording ink liquid as flying droplets, a liquid channel communicating with the ejection port, and a part of this liquid channel. Ejection energy generating means for giving ejection energy for causing the ink liquid in the path to fly. The ejection energy generating means is driven according to the image signal to eject ink droplets to record an image.

As the ejection energy generating means, for example, a method of using pressure energy generating means such as an electromechanical converter such as a piezo element is used, and electromagnetic waves such as laser are irradiated and absorbed by the ink liquid to generate heat, and the heat is generated. There are a method of using an electromagnetic energy generating means for ejecting ink, a method of using a thermal energy generating means for ejecting ink by heating an ink liquid by an electrothermal converter, and the like. Among them, the method of ejecting ink by using a heat energy generating means such as an electrothermal converter allows high-resolution recording because liquid ejection ports can be arranged at high density, and the recording head is compact. It is suitable because it can be converted into

In this embodiment, a serial type bubble jet recording method which is one of the ink jet recording methods is used as the recording means.

FIG. 8 is an exploded view of the recording head constituting the recording means, and FIGS. 9A to 9G are explanatory views of the bubble jet recording principle. Regarding the typical structure and principle, for example, US Pat. No. 4,723,1
No. 29 and No. 4,740,796.

In FIG. 8, a is a heater board, which is an electrothermal converter (discharge heater) on a silicon substrate.
b, and an electrode c made of aluminum or the like for supplying electric power thereto are formed and arranged. A top plate e having a partition wall for partitioning the liquid path (nozzle) d of the recording liquid is bonded to the heater board a. An ink cartridge for supplying ink to the recording head is replaceably attached to a predetermined position of the apparatus.

The ink supplied from the ink cartridge through the conduit is supplied to the top plate e through a supply port f.
The liquid is filled in the common liquid chamber g in the recording head, and is introduced into each nozzle d from the common liquid chamber g. Ink ejection openings h are formed in these nozzles d, and the ejection openings h are formed at a predetermined pitch in the sheet conveying direction so as to face the recording sheet of the recording head.

In this embodiment, the recording head having the above structure is mounted on a reciprocating carriage, and ink is ejected and ejected from the recording head in synchronization with the movement of the carriage to perform recording.

Here, the principle of ink flight in the bubble jet recording method will be described with reference to FIGS. 9 (a) and 9 (b).

In the steady state, as shown in FIG. 9A, the surface tension and the external pressure of the ink filled in the nozzle d are balanced at the ejection port surface. When ink is ejected in this state, the electrothermal converter b in the nozzle d is energized to cause the ink in the nozzle d to rapidly rise in temperature over nucleate boiling. Then, as shown in FIG. 9B, the ink adjacent to the electrothermal converter b is heated to generate minute bubbles, and the ink in the heated portion is vaporized to cause film boiling. The bubbles grow rapidly as shown in c).

When the bubble grows to the maximum as shown in FIG. 9D, ink droplets are pushed out from the ejection port in the nozzle d. When power supply to the electrothermal converter b is finished, the grown bubble is cooled and contracted by the ink in the nozzle d as shown in FIG. It flies from the discharge port. Further, as shown in FIG. 9 (f), the ink comes into contact with the surface of the electrothermal converter b and is rapidly cooled, and the bubbles disappear or shrink to a substantially negligible volume. When the bubbles contract, ink is supplied from the common liquid chamber g into the nozzle d by the capillary phenomenon as shown in FIG. 9 (g) to prepare for the next energization.

Therefore, the ink image is recorded on the recording sheet by reciprocating the carriage and energizing the electrothermal converter b in accordance with the image signal in synchronization with the movement.

As described above, according to the invention of the present application, bookbinding is completed by printing the desired size by designating the print size to the desired size when inputting by the print input means. Goods can be provided.

Further, the thickness of the bookbinding bundle can be controlled by detecting the thickness of the bookbinding completed product or the unbound binding before binding by the bundle thickness detecting means and limiting the input range of the character size in the print input means. Even if it changes (even if the printable area changes), it is possible to prevent the print from overflowing the printable area or the occurrence of incomplete printing.

Further, the bundle thickness detecting means provided in the bookbinding apparatus detects the bundle thickness of the bookbinding completed product or the unbound binding before binding, and the printing provided in the apparatus connected to the bookbinding apparatus through the interface. Even if the printable area changes due to a change in the thickness of the booklet bundle by limiting the character size input range with the input means, the printed characters may not stick out of the printable area or incomplete printing may occur. This can be prevented in advance, and at the same time, the input means can be shared with other input means (sheet size, number of sheets, etc.) by providing a device connected to the bookbinding apparatus without providing print input means, for example, the image forming apparatus side. it can.

Further, when a bubble jet printer is used as the printing means, the size of print dots can be reduced and the density can be increased, so that a clean print finish can be achieved.

By incorporating an outline font in the printing means, it is possible to print a desired print body.

By detecting the bundle thickness by calculating the number of sheets to be bound and the thickness of one sheet, the operator waits for the completion of the bundle of sheets for bookbinding or the completion of bookbinding (no printing) before printing. Eliminates the need to enter the size.
