However, since such conventional recording liquid containers have a high overall height, they are not suitable for use as inkjet recording devices mounted on portable electronic devices, such as thin electronic devices such as calculators with printers. In addition, since the container is mounted vertically to the electronic device, the ink drawn out from the container has a pressure equal to the water level of the ink in the container, and this pressure reaches the nozzle of the recording head, causing the ink to flow out from the nozzle. Printing defects such as leakage, splash, and satellite dots sometimes occurred. Moreover, as the water level in the recording liquid container decreases, the pressure applied to the nozzles of the recording head described above decreases, so the amount of ink supplied to the recording head changes depending on the amount of ink remaining in the container. I had to put it away.

Therefore, in order to prevent these inconvenient phenomena, a pressure detector that detects the ink pressure in the ink supply path, a pressure regulating valve that adjusts the pressure, and a constant amount of ink that is constantly supplied to the nozzle are required. It became necessary to provide an ink supply pump, etc.
However, in order to incorporate an inkjet recording device into a small electronic device such as a portable calculator with a printer, it is necessary to reduce the number of parts and simplify the structure to reduce the size of the device.
Furthermore, since the capacity of the recording liquid container in a calculator with a printer is limited, it is necessary to frequently replace the recording liquid container, and it is desirable that the replacement work be easy and reliable. Therefore, it is not preferable to provide a pressure detector or the like as described above, as it goes against these demands.
