  • Patent number: 4703178
    Abstract: An apparatus for erasing fog in the form of environmentally induced radiation energy stored in a stimulable phosphor sheet used for radiation image recording and reproducing, wherein a radiation image is once recorded in the stimulable phosphor sheet and then read out and reproduced on a recording material. The apparatus includes a power supply to a lamp for emitting erasing light, and a power controller connected between the power source and the lamp for maintaining at a predetermined constant value the power supplied to the lamp, thereby to keep constant the luminance and color temperature of the lamp.

  • Patent number: 4697902
    Abstract: A device for containing a radiation recording medium includes an opening through which the recording medium is placed and a light shutting plate for closing the opening to prevent light from penetrating into the casing. A light shutting plate is provided integral with a handle. A locking mechanism is provided for bringing a casing into locking engagement with the light shutting plate. Since the device is moved by holding the handle with the light shutting plate locked on the casing, there is no possibility that the film will be inadvertently exposed to light with the shutter plate left unclosed.

  • Patent number: 4672184
    Abstract: A bar code reader system for scanning light reflective bar coded labels, including a pivotably mounted spring based housing member having a connecting arm, a light source mounted on the housing member, and a line scan sensor mounted in the housing for sensing reflected light from the bar code label and producing coded signals corresponding thereto. Spring biasing of the housing urges the connecting arm against a plane parallel to the sheet having the bar code label to be read, with the housing pivoting about a pivot axis under spring biased urging, to maintain substantially constant the distance between the bar code label to be read and the line scan sensor.

  • Patent number: 4667102
    Abstract: A radiographic system for obtaining a visible radiation image using a stimulable phosphor sheet, including an improved spot shot apparatus having a transport system for transporting the stimulable sheets from a supply magazine to a receiving magazine through a park and exposure station where exposure to radiation occurs. A plurality of the sheet are stacked in the supply magazine and are sequentially transported through the exposure station to the receiving magazine by the transport system. The transport system has independent transport portions for transporting a stimulable phosphor sheet from the supply magazine to the receiving magazine through the exposure station. One transporting channel is disposed between the supply magazine and the exposure station and retains the unexposed stimulable phosphor sheet until an advanced stimulable phosphor sheet is exposed to form and store radiographic image therein and is fed toward the receiving magazine.

  • Patent number: 4663528
    Abstract: A radiographic system for obtaining a visible radiation image by use of a stimulable phosphor sheet including a spot shot apparatus having a transport system for transporting the stimulable sheets from the supply magazine to the receiving magazine through a park and exposure station at which radiation is directed to the sheets. A plurality of the sheets are stacked in a supply magazine with the side of each sheet opposite the side having the phosphor layer facing upward. The sheets are sequentially transported to the exposure station for radiographic imaging, and then to a receiving magazine by a transport system. The receiving magazine includes a light-tight receiving magazine including one side having an access opening for receiving the exposed stimulable phosphor sheets. A removable shutter is insertable in the receiving magazine to block the access opening, and maintains the light-tight environment when the magazine is inserted in and removed from the housing structure defining a spot shot apparatus.

  • Patent number: 4618979
    Abstract: A main carriage has four wheels each of which is supported by a corresponding guide rail. The main carriage is reciprocated between a standby position and a photographing position along the guide rails through the wheels. The wheels engaged with the guide rails at the two sides of the apparatus housing are rotatably mounted at the main carriage. The wheel engaged with the edge of the main carriage at the side of a film convey mechanism is mounted on the main carriage to be movable along its moving direction (X direction). A guide plate is fixed on a main body of the main carriage, and a guide hole is formed in the guide rail to extend along the X direction. A pair of supports are engaged in the guide hole, and a support plate is fixed to the supports. A wheel is rotatably mounted on an end of the support plate. The support plate is biased by a tension spring in the retracting direction of the main carriage.
