A lower guillotine cutter blade (2) is mounted to a frame (1). A guillotine cutter-blade holder (3) holds an upper guillotine cutter blade (4) and vertically reciprocates with respect to the lower guillotine cutter blade (2). Rods (6) are vertically slidably mounted to the guillotine cutter-blade holder (3). A pressing plate (5) is secured to the lower ends of the rods (6). Springs (7) are fitted around the rods (6) between the guillotine cutter-blade holder (3) and the pressing plate (5) for downwardly elastically biasing the rods (6) so that the heads (6a) of the rods are kept abutted against the guillotine cutter-blade holder (3). In a cutting operation, after the pressing plate (5) is brought into abutment with a batch of paper (20), the guillotine cutter-blade holder (3) is further downwardly moved, thereby causing the lower and upper guillotine cutter blades (2 and 4) to cut the batch of paper (20) and also causing the heads (6a) to upwardly protrude from the guillotine cutter-blade holder (3). At this time, a sensor (8) mounted to the guillotine cutter-blade holder (3) detects the distance to the heads (6a). A thickness measuring element (27) determines the thickness of the batch of paper (2) on the basis of the detection signal.

There are provided an apparatus capable of complying with arbitrary data acquisition period (frame rate) change instruction without increasing load and cost, and a method and a system for controlling such an apparatus. To realize this, in the present invention, there are included an area sensor for reading out an electric signal accumulated in a plurality of pixels arranged in a matrix, line by line, and a control unit for controlling the area sensor. The area sensor operates in a first operation for deriving radiation image data by reading during irradiation with radiation, and a second operation for deriving the radiation image data by reading during non-irradiation with radiation, alternately. The control unit switches a period for deriving the radiation image data during a time period from an end of the reading in the first operation until an end of the reading in the second operation.

An optical module is configured with a combination of a single-mode oscillating light source and an optical filter. In this optical module, the single-mode oscillating light source outputs a single-mode, frequency-modulated signal. Further, the optical filter converts the frequency modulation to an amplitude modulation. And, the single-mode oscillating light source and the optical filter are packaged without active alignment on the same substrate. Accordingly, it is possible to realize an optical module in a simple and low-cost configuration by packaging the single-mode oscillating light source and the optical filter by passive alignment, without active alignment, on the same substrate, and by using a simple optical filter such as a waveguide ring resonator, which converts a frequency modulation to an amplitude modulation.
