摘要： A sheet feeding unit includes a sheet forwarding unit for forwarding sheets from a sheet storing unit, a key input portion, a sheet detection gate, and a control unit. In one embodiment, the sheet forwarding unit repetitively performs its function after an operation start instruction until either the sheet detection gate detects a sheet from the feeding cassette or until the number of repetitions of the sheet forwarding unit reaches a predetermined number. An error process is performed when the number of repetition reaches the predetermined number without the gate detecting a sheet. Also, the sheet feeding unit compares the number of times a sheet is fed from the sheet feeding unit with the number of times the sheet if forwarding to determine the status of the feeding roller.
摘要翻译：送纸单元包括用于从纸张存储单元，键输入部分，纸张检测门和控制单元转送纸张的纸张转发单元。在一个实施例中，片材转发单元在操作开始指令之后重复执行其功能，直到片材检测门检测到来自馈送盒的片材或直到片材转发单元的重复次数达到预定数量。当重复次数达到预定数量而没有门检测到纸张时，执行错误处理。此外，送纸单元将从供纸单元供纸的次数与纸张的次数进行比较，以确定进纸辊的状态。

摘要： An image reading apparatus includes a document feed unit that can adopt a first attitude to sandwich a document against a document table and a second attitude to release the document. An attitude detection unit detects the attitude of the document feed unit. A document detection unit detects whether a document is on a placement section of the document feed unit. An input acceptance unit accepts a selection input indicating whether a document on the document table is a read object document when attitudes of the document feed unit have been detected in a second-to-first sequence by the attitude detection unit when a document is detected on the document placement section. A control unit sets a document on the document table as the current read object, when the input acceptance unit accepts a selection input indicating that the document on the document table is to be a read object document.

摘要： A paper supplying deck is insertable into and withdrawable from a paper supplying portion of a body resulting in electrical connection between the side of the paper supplying deck and the side of the body through a drawer-type connector when the paper supplying deck is inserted and interruption of such electrical connection when the drawer is withdrawn. The paper supplying deck has a paper carrying portion with a paper width setting mechanism and a variable resistor the resistance value of which is changed in dependence on the paper width setting mechanism, thereby changing an output paper width detecting voltage. On the wide of the paper supplying deck, a resistance which prevents the paper width detecting voltage from amounting to a power source voltage even though the resistance value of the variable resistor reaches a maximum value, is connected in series with the variable resistor. On the side of the body, a pull up resistance is connected with the connector to discriminate between voltages in the connector when the paper supplying deck is mounted and when the paper supplying deck is not mounted.
