Abstract
An image recorder includes a punch unit for punching a hole in a plate. The punch unit has six punchers disposed movably. Punches of the punchers can punch holes of different configurations. A punch of a required configuration moves to a required location toward a plate prepared on an upper tray of a feed/discharge unit. After a hole is punched in the plate by this punch, the plate is fed to a drum. This allows changes in the location of a punched hole in the plate without the need to simply increase the number of punchers when the range of plate sizes mountable on the drum is expanded. If competition in punch standards occurs, the image recorder allows a required puncher to be situated in a desired location.
Claims5
An image recorder comprising:
- a recording drum for mounting an image recording material thereon with reference to at least one positioning part provided on a surface thereof;
- an image recording element for directing an optical beam modulated in accordance with an image signal onto the image recording material mounted on said recording drum, thereby to record an image on said image recording material;
- a punching element having a puncher for punching a hole engageable with said positioning part in said image recording material;
- a moving element for moving said punching element in a direction parallel to the axis of rotation of said recording drum;
- and
- a feed element for feeding said image recording material punched with a hole by said puncher to said recording drum, wherein
- said feed element comprises
- a fixing member for fixing said image recording material,
- wherein said moving element moves said punching element while said image recording material is fixed to said feed element by said fixing member, and
- said puncher comprises
- a guide member having a guide part for guiding said image recording material,
- a punch for punching a hole in said image recording material having reached said guide member,
- a reference pin disposed in a predetermined positional relationship with said punch for positioning a leading edge of said image recording material with respect to said guide member, and
- a reference pin moving member for moving said reference pin between a first location for positioning of said image recording material and a second location clear of said guide part,
- wherein said reference pin moving member moves said reference pin clear of said guide part before said moving element moves said punching element.
