  "abstract": "A storage device is used in a printing device includes a storage section having a transfer stage for loading and unloading the exchange target object to and from the printing section, the storage section being configured to accommodate multiple placement sections, each for placing the exchange target object, and to store the exchange target object, a placement section moving section configured to move any one of the placement sections to the transfer stage, and a target object moving section disposed on the transfer stage, the target object moving section being configured to move between a retracted position allowing the placement section to pass and an abutting position abutting against the exchange target object on the placement section and to move the exchange target object in a loading/unloading direction while abutting against the exchange target object at the abutting position.",
  "claims": [
    "1. A storage device of a printing device including a printing section configured to perform a viscous fluid printing process on a printing target using an exchange target object including a screen mask, the storage device comprising: a storage section having a transfer stage for loading and unloading the exchange target object to and from the printing section, the storage section being configured to accommodate multiple placement sections for placing the exchange target object, and to store the exchange target object; a placement section moving section configured to move any one of the placement sections to the transfer stage; and a target object moving section disposed on the transfer stage, the target object moving section being configured to move between a retracted position allowing the placement section to pass and an abutting position abutting against the exchange target object on the placement section and includes at least one pair of gripping members to move the exchange target object in a loading/unloading direction while abutting against the exchange target object at the abutting position; and a loading/unloading section being stored in the storage section and being disposed on the transfer stage, the loading/unloading section being configured to pull the exchange target object into the storage section or to push the exchange target object out of the storage section by protruding outward from the storage section.",
    "2. The storage device according to claim 1, wherein the at least one pair of gripping members configured to move between the retracted position and the abutting position and to grip an end portion of the exchange target object and at least one pair of conveyance rollers configured to move together with the at least one pair of gripping members and to move the exchange target object in the loading/unloading direction.",
    "3. The storage device according to claim 2, wherein the at least one pair of gripping members are each a belt being configured to be wound around a conveyance roller of the at least one pair of conveyance rollers to be driven by the conveyance roller, and to abut against the exchange target object.",
    "4. The storage device according to claim 1, wherein in a placement section of the placement sections, multiple support rollers supporting at least an end portion of the exchange target object are disposed.",
    "5. The storage device according to claim 1, further comprising: a door section configured to move between a restricted position where movement of the exchange target object on the transfer stage in the loading/unloading direction is restricted and an open position where movement of the exchange target object in the loading/unloading direction is allowed.",
    "6. The storage device according to according to claim 1, wherein the loading/unloading section has at least one pair of holding members configured to hold an end portion of the exchange target object disposed outside the storage device and at least one pair of loading/unloading rollers configured to move together with a holding member of the at least one pair of holding members and to move the exchange target object in the loading/unloading direction.",
    "7. The storage device according to claim 1, wherein the loading/unloading section has at least one pair of holding members configured to hold an end portion of the exchange target object disposed outside the storage device and at least one pair of linear motion driving sections configured to move the exchange target object in the loading/unloading direction together with holding member.",
    "8. The storage device according to claim 1, wherein the loading/unloading section has a hooking member configured to hook an end portion of the exchange target object disposed outside the storage device and to move the exchange target object in the loading/unloading direction, a guide member configured to guide the hooking member between a protruding position, protruding to an outside of the storage device, and a retreated position inside the storage device, and a driving section configured to move the hooking member along the guide member.",
    "9. A printing system comprising: the storage device according to claim 1; and a printing device including a printing section configured to perform a viscous fluid printing process on a printing target using an exchange target object including a screen mask pushed from the storage device.",
    "10. A storage device of a printing device including a printing section configured to perform a viscous fluid printing process on a printing target using an exchange target object including a screen mask, the storage device comprising: a storage section having a transfer stage for loading and unloading the exchange target object to and from the printing section, the storage section being configured to accommodate multiple placement sections for placing the exchange target object, and to store the exchange target object; a placement section moving section configured to move any one of the placement sections to the transfer stage; and a target object moving section disposed on the transfer stage, the target object moving section being configured to move between a retracted position allowing the placement section to pass and an abutting position abutting against the exchange target object on the placement section and to move the exchange target object in a loading/unloading direction while abutting against the exchange target object at the abutting position, wherein the target object moving section includes at least one pair of gripping members configured to move between the retracted position and the abutting position and to grip an end portion of the exchange target object and at least one pair of linear motion driving sections configured to move the exchange target object in the loading/unloading direction together with gripping member."

  "description_excerpt": "The present specification discloses a storage device and a printing system.\n\nConventionally, for example, in a printing device that performs a viscous fluid printing process on a printing target, such as a board, using a screen mask, a printing device that performs automatic exchange of the screen mask has been known. For example, Patent Literature 1 discloses a printing device including a rod that protrudes downward and a slider that causes a screen mask to slide by moving the rod to put a main body frame in and out.\n\nHowever, although multiple storing shelves for placing screen masks are provided in the printing device described above, the configuration is complicated since each storing shelf includes a belt conveyor for putting the screen mask in and out.\n\nThe present disclosure has been made in view of such problems, and a main object thereof is to provide a storage device and a printing system, which can simplify a configuration for loading and unloading an exchange target object to be stocked for a printing device use.\n\nThe storage device and the printing system, which are disclosed in the present specification, adopt the following means in order to achieve the main object described above.",
