摘要:
A printing apparatus that includes printing element substrates which are provided with printing elements that discharge ink. A plurality of temperature sensors, each of which is provided with one of the printing element substrates, measures a temperature of a corresponding printing element substrate. A selection unit selects any one of the temperature sensors, and a determination unit performs a determination operation to determine a state of the printing element substrate based on the temperature measured by the selected temperature sensor in a case when only the printing elements of a substrate that corresponds to the selected temperature sensor are driven. The determination unit performs the determination operation on a first substrate and then on a second non-adjacent substrate.

A spindrier according to the present invention includes a box body enclosing a plurality of wafers, a rotor for holding the wafers in the box body and rotated by a motor, and upper and lower clamp bars for holding the wafers face to face with their faces directed perpendicular to rotating shafts of the rotor. The lower clamp bars are connected and fixed to the rotating shafts so as to hold lower rim portions of the wafers thereon when the wafers are set in the rotor. The upper clamp bars are connected to one of the rotating shafts at their base ends so that they can be swung vertically erect and also and horizontally relative to the rotating shaft and they are locked to the other rotating shaft at their front ends when they are swung horizontally. They include a mechanism for swinging them, a locking mechanism for locking their front ends to the other rotating shaft, and an unlocking mechanism for releasing their front ends from the other rotating shaft.

There is provided an inkjet printing apparatus which can output a stable image without density unevenness by performing appropriate drive control to print elements based upon an appropriate representative temperature of a chip whatever image data is printed on a print medium. For this purpose, detection temperatures of a plurality of temperature sensors are lined up in high temperature order, and coefficients by which the respective detection temperatures are multiplied, are determined to be associated with that order at the lining-up, determining a representative temperature by the weighted average method. The common drive pulse associated with to the individual chip based upon the representative temperature thus obtained, to be applied thereto. Thereby even if temperature variations of print elements on the chip exist, it is possible to appropriately control the entire chip in temperature.

A transfer machine having a pair of holding members disposed opposite to each other to hold a plurality of objects arranged at their peripheral edges. A drive mechanism selectively moves the holding members toward and away from each other in order to selectively hold and release the objects by the holding members. A transfer mechanism transfers the objects and the holding members to a bath in order to process the objects in the bath. Each of the holding members has a plurality of holding notches for holding the peripheral edges of the objects, and the notches are disposed in upper and lower holders which are arranged parallel to each other. The holding notches of the upper holder have a first taper part positioned adjacent an opening of the notch and a second taper part positioned adjacent a notch bottom, and the first taper part has an opening angle larger than an opening angle of the second taper part.

A substrate transporting device and method 19 transports a plurality of wafers W standing upright in a row, from a previous process, i.e., a cleaning process. A substrate holder 40 is carried by a transporting device 50 arranged outside a drying chamber 20. The substrate holder 40 receives the wafers W from the substrate transporting device 19 while maintaining a posture of the wafers W. The transporting device 50 lowers the substrate holder 40 and sequentially moves it into the drying chamber 20 through an unloading and loading port 21 above the drying chamber 20. Thereafter, the substrate holder 40 is fixed to a rotor 30. After closing the unloading and loading port 21 with a lid body 25, the rotor 30 is rotated. In this way, moisture sticking to surfaces of the wafers W is eliminated.
