摘要:
An image detection device having pixel electrodes arrayed in a matrix in an image detection area on one face of an insulating film. A shield electrode is disposed in the peripheral area on the outside the detection area, and a driving circuit for driving the pixel electrodes and wires connecting the pixel electrodes are provided on the other face of the insulating film. The driving circuit may be provided in the peripheral area. The wires disposed in the peripheral area are shielded by the shield electrode to prevent electrostatic breakdown even when a large current flows through a photoelectric converting film, thereby to improve reliability by preventing dielectric breakdown and to accommodate a large dynamic range of incident light.

An X-ray flat panel detector includes an X-ray photosensitive film which generates signal charges upon being exposed to incident X-rays, pixel electrodes which are arrayed in contact with the X-ray photosensitive film, a bias voltage application unit which applies a bias voltage to the X-ray photosensitive film so as to make the pixel electrodes collect holes or electrons, which serve as the signal charges generated by the X-ray photosensitive film and have a higher mobility, capacitors which are arranged in correspondence with the pixel electrodes and store the charges generated by the X-ray photosensitive film, switching thin-film transistors which are arranged in correspondence with the pixel electrodes and read the charges in the capacitors, scanning lines which supply a control signal to OPEN/CLOSE-control the switching thin-film transistors, and signal lines which are connected to the switching thin-film transistors to read the charges when the switching thin-film transistors are opened.

An image detecting device has a large dynamic range that deals with a plurality of image detecting modes. The image detecting device is composed of pixels e (i, j) arranged in a matrix array. Each pixel has a photoelectric element. In each pixel, a capacitor 102 and a protecting diode 103 are disposed. The capacitor 102 stores electric charge corresponding to the intensity of penetrated light to the relevant pixel. The protecting diode limits the capacitance. A bias voltage is supplied to the protecting diode 103 through a bias line Bias. The bias voltage is adjusted by a bias voltage controlling system 133 corresponding to the frame rate. Thus, the influence of a leak current in the off-state of the protecting diode 103 can be alleviated against electric charge stored in the capacitor 102. Consequently, an image with a high S/N ratio can be obtained regardless of the frame rate.

Thus, it is possible to provide an X-ray image detector system capable of detecting an image even if X-ray irradiation is weak.

The lowest voltage value among the open circuit voltages at cells constituting a battery pack is set as a capacity adjustment target value. Each cell is discharged over the length of time corresponding to the deviation of its open circuit voltage from the capacity adjustment target value. The voltage at a cell manifesting a voltage reduction that is larger than those at a majority of remaining cells but is still within the normal range is set closer to the level of the voltages at the majority of remaining cells over time. If, on the other hand, an open circuit voltage is lowered to an extent exceeding a first threshold value, from the range set by the cell error decision-making reference value ascertained by averaging the cell voltages excluding the highest voltage value and the lowest voltage value, then the decision is made that an abnormal voltage reduction has occurred.

A lead frame magazine conveying device including magazine guides that guide the lead frame magazine to be conveyed. The magazine guide comprises a fixed guide and a movable guide which is a bar attached at the end of a swing lever. When the movable guide is brought into contact with one side of the lead frame magazine, the swing lever is tightened by a screw so as not to swing, thus turning the movable guide so as to be immovable, making it possible to smoothly guide the lead frame magazine in cooperation with the fixed guide which is in contact with another side of the lead frame magazine.
