摘要： A cut sheet feeding device having a function of detecting a skew of the sheet to be fed is incorporated in an image reader, a printing apparatus, etc. The cut sheet feeding device is capable of surely detecting the skew of a document without an operator visually monitoring the same. The cut sheet feeding device has size sensors corresponding to standard sheet sizes, respectively, for detecting the size of a document that is being fed along a feeding path. The detected document size is compared with a set document size stored in advance. If the detected document size is greater than the set document size, it is determined that there is an abnormality in feeding the document. The cut sheet feeding device also has a document passage detector for detecting the passage of the document. The outputs of the document passage sensor and size sensor are compared with each other, to calculate a skew of the document that is being fed. This skew is used to determine whether or not the document is being fed normally.

摘要： An apparatus having an ink-jet head has a time measuring unit, a recording unit, and a prefiring operation control unit. The time measuring unit is used to measure an elapsed time from execution of prefiring operations for the ink-jet head, and the recording unit is used to record whether or not printing nozzles disposed in the ink-jet head are operated. The prefiring operation control unit determines a number of prefiring operations in accordance with a measurement result obtained by the time measuring unit and operated conditions of the printing nozzles recorded in the recording means, and executes prefiring operations for the ink-jet head. Therefore, the apparatus is capable of executing prefiring operations often enough and sufficient for the actual operated conditions of the printing nozzles disposed in the ink-jet head, and thereby preventing ink from being consumed at enhanced rate by useless prefiring operations.

摘要： This invention relates to an automatic staining apparatus for staining many slide specimens such as tissue specimens by dipping them sequentially into a large number of chemical solution containers while they are mounted in a slide holder basket.Conventional automatic staining apparatuses have a problem in the staining efficiency because a basket is attached manually to a clamp member of the apparatus, and also have another problem that remaining chemical solution cannot be sufficiently removed from slide specimens.In order to solve these problems, an automatic staining apparatus according to the first present invention has the clamp member which can automatically engage with, and disengage from a basket, so that the staining efficiency is much improved. Preferred embodiment of the invention has a tilting mechanism for the clamp member, so that chemical solution is sufficiently removed from slide specimens.Another automatic staining apparatus according to the second invention has n (an integer of 2 or more) clamp members, each of which is characterized by the same as the first invention, and (n-1) relay stations inside the apparatus, so that a basket can be relayed automatically from one clamp member to another inside the apparatus and staining can be carried out for maximum n baskets at same time and independently from each other. Therefore, the rate of operation of staining apparatus is substantially maximum n-times. Preferred embodiments of the second invention also has a tilting mechanism for each clamp member, so that chemical solution is suffieciently removed.
