  • Patent number: 11249430
    Abstract: An image forming apparatus includes an image forming section, a discharging section, and a controller. The image forming section performs printing of an image on a medium on the basis of received print data. The discharging section executes discharging operation and holding operation. The discharging operation is operation of discharging the medium subjected to the printing by the image forming section from a discharging slot to an outside. The holding operation is operation of holding the medium while exposing a portion of the medium from the discharging slot to the outside. The controller selects one of the discharging operation and the holding operation on the basis of attribute information included in the print data, and causes the discharging section to execute the selected one of the discharging operation and the holding operation.

  • Patent number: 6612762
    Abstract: The present invention is intended to provide an economical printer which is simple in structure and uses a common tray but is capable of adapting itself to various recording media of different shapes. Adapters in which recording media can be firmly held can be selectively mounted in the tray. An adapter 24 has an oval opening 24a in which a recording medium 30 can be placed. The contour of the adapter 24 can fit into a recessed portion 23a formed in the tray 23. The recording medium 30 is firmly held in the adapter 24. When the adapter 24 is mounted in the recessed portion 23a in the tray 23, a keyway 23b and a protrusion 24b engaging the keyway 23b prevent the adapter 24 from shifting out of position; the adapter is held in the tray 23. Prints can be made in accurate positions on the recording medium 30.

  • Patent number: 6059464
    Abstract: A camera comprises a film cartridge chamber for accommodating a film cartridge containing a film. The film cartridge has a first rotational shaft. An operating member is mounted for rotation in first and second opposite directions by manual operation for winding and rewinding the film, respectively. A second rotational shaft is provided for connection to the operating member during rotation of the operating member in the first direction. A wheel train transmits rotational movement of the operating member to the first rotational shaft to wind and rewind the film. A first clutch mechanism disconnects transmission of rotational movement by the wheel train when a tensional state of the film is generated.

  • Patent number: 6033127
    Abstract: A camera comprises an operating member mounted for rotation in first and second opposite directions by manual operation for winding and rewinding a film, respectively. A rotational winding member is mounted for connection to and disconnection from the operating member. A control member is mounted for movement between first and second positions for controlling the rotating direction of the operating member. When the control member is disposed in the first position, the operating member can be rotated only in the first direction and the rotational winding member is connected to the operating member for rotation therewith to wind the film. When the control member is disposed in the second position, the operating member can be rotated only in the second direction to rewind the film while the rotational winding member is disconnected from and does not rotate with the operating member.
