CONSTITUTION:When an X-ray tube 1 and an X-ray detector 2 are subjected to linear scanning from position A to position B by driving a pedestal 3, a light beam irradiated from a projector 4a is broken by a body P to be tested; the detecting signal at the interruption of light is output from a light detector 5a to a signal generating circuit SG for the period of exposure. At the same time, the detecting signal from a position detector SP of the pedestal 3 is input into a circuit SG; and with the timing of right end the body P to be tested, the X-ray exposure is started by a power source switching circuit SC. Next, the light beam of a projector 4b is also broken, and consequently, the interruption of the projector 4a side is recovered, these signals are detected by the circuit SG, thus the X-ray exposure is stopped with the timing of the left end of the body P to be tested. Consequently, the X-ray exposure can be controlled to necessary minimum and also the heat capacity of the X-ray tube can be decreased.

Title: Recording apparatus
Inventor: SASAMA KAZUO
IPC: B41J2/05
Filed: 1987-06-29
Abstract: PURPOSE:To avoid the decline of printing density and the generation of uneven printing and also prevent the breakage of a heat generating element resulting from the thermal accumulation, by sequentially changing during the transfer of a recording medium an angle defined by a tangent line of the recording medium and a position where the heat generating element is placed in a thermal head, thereby to fill ink instantaneously into an emptied minute hole. CONSTITUTION:During the transfer of a film 2, eccentric cams 58 and 59 are rotated to successively move tension rods 54 and 55 in a vertical direction, so that an angle alpha of the film 2 is sequentially changed in the cycle of 1-100Hz. When the angle alpha is small, the position of a contacting point between the film 2 and an element 36 to which ink is supplied comes closer to a heat generating element 5, and accordingly the ink can be smoothly supplied to the position where the element 5 is placed. On the contrary, when the angle alpha is large, the above-described position is far away from the heat generating element 5, resulting in increase of the contact area between the film 2 and the element 36. Therefore, the film 2 and the element 36 are tightly and stably adhered to each other. Accordingly, even when there is an empty minute hole 1 discharged from the drops of ink on the element 5 at the application time of pulses, the minute hole 1 can be immediately supplied and filled with the ink. Moreover, since sufficient ink is supplied in the vicinity of the element 5, the element 5 is able to be prevented from being damaged in the early life stage thereof resulting from the thermal accumulation.
