A voltage measuring apparatus measures an output voltage of an assembled battery in which a plurality of unit cells are connected in series and are divided into a plurality of blocks. The apparatus includes: a block voltage detection section which detects a voltage of at least one of the plurality of blocks and provides an analog voltage signal; a reference power supply which generates a reference voltage; a sampling voltage generation section which generates a sampling voltage based on the reference voltage; a storage for storing voltage date corresponding to the sampling voltage; and an A/D conversion section of the block voltage detection section that digitizes the sampling voltage with the reference voltage for A/D conversion. A difference between the digitized sampling voltage and the voltage data is calculated and it is determined that abnormality occurs in the A/D conversion section when the difference is larger than a threshold.

A switch element is configured to decrease an impedance of a voltage-detection integrated circuit that detect voltage between both ends of unit cells of a higher-ordered battery block, for adjacently-connected pair of the higher-ordered battery block and a lower-ordered battery block. The voltage-detection integrated circuit is configured to detect disconnection of an electrical wire when voltage between both ends of a lowest-ordered unit cell that is detected with the switch element turned on is equal to or lower than a threshold.

A document reading apparatus has a controller for conveying original documents from a section for loading documents via a section for reading documents to a section on which the documents are stacked, and controlling an operation of reading the documents. The apparatus includes respective sections for reporting apparatus information, detecting a start instruction when reading a document, and counting sheets conveyed to the reading section. If the reading operation is suspended in the event of an error, the controller instructs the reporting section, when resuming the reading operation, to report the loading on the loading section of documents, including already-read documents, the controller subsequently controls conveyance of documents when the detecting section detects the start instruction, to set the conveyance speed of the already-read documents faster than the conveyance speed of subsequent documents on which the reading operation was suspended, based on the number of sheets counted until the suspension.

A control circuit turns on a switching element to discharge a capacitor, and after a voltage between both ends of the capacitor becomes zero, the control circuit turns off the switching element. The control circuit measures the voltage V1, V2 between both ends of the capacitor after the first predetermined time is passed and after the second predetermined time is passed, and calculate a change rate (V1/V2). If V1/V2 is equal to or less than 0.5, the disconnection is detected.
