Abstract: The objective of the present invention is to provide an ejection detection device with an inexpensive and simple structure that can appropriately detect conditions of nozzles, without the control of the quantity of liquid ejected from the nozzles being required. Therefore, for the ejection detection device of the present invention, a light-emitting unit emits light to a light-receiving unit in a direction in which a plurality of nozzles is arranged in a print head. The ejection detection device detects the condition of a nozzle to be detected, which ejects the liquid droplet. At this time, the emission intensity of the light-emitting unit or the responsivity of the light-receiving unit is controlled by the print head in accordance with the location of the nozzle to be detected.

Abstract: An image reading apparatus sets an irradiation region below a fixed reading glass when light guide members diffuse light of LEDs upward so that the irradiation region corresponding to a significantly sagged portion in a main scanning direction is wider than that corresponding to portions on both sides of the significantly sagged portion, and sets a light intensity of a plurality of LEDs corresponding to the significantly sagged portion in the main scanning direction to be larger than that of a plurality of LEDs corresponding to the portions on both sides of the significantly sagged portion. Therefore, the degradation of the illuminance corresponding to the significantly sagged portion due to the pressed fixed reading glass can be prevented, and the entire document can be read with uniform reading precision.

Abstract translation: 当导光部件向上扩散LED的光时，图像读取装置将照射区域设置在固定的读数玻璃下方，使得与主扫描方向上的显着下垂部分对应的照射区域比对应于主扫描方向两侧的部分的照射区域宽 并且将与主扫描方向上的显着下垂部分对应的多个LED的光强设定为大于对应于显着下垂部分两侧部分的多个LED的光强度。 因此，可以防止由于按压的固定读数玻璃而对应于显着下垂的部分的照度的劣化，并且可以以均匀的读取精度读取整个文档。

Abstract: An inkjet printing head prints an image on a printing medium located at a printing position facing the printing head, by a printing operation in which the printing head ejects ink onto the printing medium, and the printing head is capable of resuming the printing operation after suspension of the printing operation. A supporting unit supports the printing medium on which the image is printed by the printing head, and an adjusting unit is capable of adjusting a facing distance between the printing head and the supporting unit. A control unit controls the adjusting unit so that the facing distance is greater than that during the printing of a printed image, in case the printing operation is resumed and the printed image moves relative to the printing position. The control unit controls the adjusting unit based on the time elapsed between the suspension of the printing operation and the resumption of the printing operation, so that the facing distance is greater as the elapsed time is longer.
