Abstract
On a base (12) are fixed a pair of supporting members (6, 8). A guide rail (3) is supported by the pair of supporting members. A measurement block (2) is guided by the guide rail in a sliding manner. On the base is fixed a reference block (10) abutted by the measurement block when it has reached one end of the guide rail. A moving-distance measuring device is provided which uses as a zero point a position where the measurement block abuts against the reference block, to measure a distance over which the measurement block has moved with respect to the reference block. The moving-distance measuring device has, on the base, a pair of pulleys (5, 7) arranged with a gap therebetween in a direction parallel to the guide rail, a belt (4) engaged over the pair of pulleys and having its part linked with the measurement block, and a rotary encoder (11) linked to a rotary shaft of one of the paired pulleys. By sandwiching predetermined portions of a book block and a book cover between the reference block and the measurement block, the size can be measured and thus obtained measurement values are input from the measuring device to a controller device. The controller device, based on these measurement values, controls the carrier mechanism and the processing units of the book binding system.
