The present invention relates to the technical field of optical film production, and provides a light guide film production device, including a feeding unit, a fusion stirring unit, an extrusion molding unit, a cooling shaping unit, a guide leveling unit, a flattening unit, and a finished product winding unit. The cooling shaping unit is provided with a first water tank to perform heat exchange on an extruded light guide film for heat recovery, so that edge film pressing mechanisms press pressure blocks at the edge film positions using the memory effect of a memory alloy. Circulating water of the first water tank subjected to heat exchange is delivered to a second water tank disposed in the flattening unit, so that a first conveyor belt made of the memory alloy in a third drive device drives a second rolling roller set to rotate to realize secondary utilization of recovered heat. In the present invention, an air delivery mechanism with one airflow pipe to the cooling shaping unit, and the other airflow pipe to the flattening unit is further provided. According to the present invention, the heat of the light guide film production process is used to improve the quality of the light guide film and reduce the energy consumption of the light guide film production process.

A sheet conveyance apparatus includes a conveyance path including a first path through which the sheet is conveyed toward a sheet processing apparatus, and a second path branched from the first path, a switching guide configured to switch a conveyance route of the sheet between the first path and the second path, an air blowing unit configured to send air toward the conveyance path, and an air blowing port configured to blow the air from the air blowing unit to the conveyance path. The air blowing port is arranged upstream of the switching guide in a sheet conveyance direction of the first path, and configured to blow the air toward a downstream side in the sheet conveyance direction.

A sheet discharge apparatus includes a discharge unit configured to discharge a sheet in a discharge direction, a stacking surface configured to stack the sheet discharged by the discharge unit, and a wall including a plurality of hole portions and an abutting part, wherein the plurality of hole portions includes a first hole portion disposed across an extension line along the stacking surface when viewed in a width direction, the first hole portion including a first edge portion and a second edge portion, the first edge portion being positioned on a side of the stacking surface, and wherein, in the vertical direction, an upper end of the first edge portion of the first hole portion is positioned above the extension line, and a lower end of the first edge portion of the first hole portion is positioned below the extension line.

An attachment mechanism includes a first holding member and a second holding member. The first holding member is configured to hold a device side plate of a belt device to attach a main body side plate of an apparatus in which the belt device is incorporated. The second holding member is configured to be fixed to the first holding member. The first holding member and the second folding member are configured to adjust a posture of the device side plate with respect to the main body side plate in assembly of the belt device.

The relay conveyance apparatus includes a casing, an opening, a cover, a conveyance guide, a protruding part and a cooling mechanism. The casing has an inner space in which a relay conveyance path is formed. The opening is formed in the casing. The protruding part is provided in the cover. When the conveyance guide is switched to a path formation position, the protruding part is inserted into the inner space of the casing to allow closing of the cover, and when the conveyance guide is switched to a path opening position, the protruding part interferes with the conveyance guide to restrict the closing of the cover. The cooling mechanism includes a main duct, a fan and an air blowing port. The air blowing port is provided in the protruding part, and through which the cooling air is blown from the main duct to the relay conveyance path.

A vacuum coating device for a flexible substrate is provided, including a vacuum coating chamber and a transition chamber which are connected to each other. The vacuum coating chamber and the transition chamber communicate with each other through a slit. The vacuum coating device further includes a cooling roller, which is fixed in the transition chamber through a tension adjusting component. The cooling roller includes a roller body and a shaft, the roller body is fixedly installed on the shaft, and the roller body and the shaft are coaxial. Multiple heat dissipation passages are provided in the roller body along an axial direction of the roller body. Good cooling function is achieved and the flexible substrate is prevented from generating winkles.

A sheet stacking device includes a stacker, a detector, a blower, and a moving device. A sheet is stacked on the stacker. The detector detects a stacking amount of the sheet on the stacker. The blower blows air to the sheet stacked on the stacker. The moving device moves the blower with respect to the stacker based on the stacking amount of the sheet detected by the detector.

A printer includes a printing unit to form a toner image on a printing medium, a fuser to apply heat and pressure to the printing medium that has passed through the printing unit to fuse the toner image on the printing medium, and a liquid-vapor chamber having a length in a width direction of the printing medium greater than a width of the printing medium. The liquid-vapor chamber has a heat absorber side to face the printing medium to absorb heat from the printing medium, a condenser side apart from the heat absorber side in an opposite direction not facing the printing medium to form an inner space between the condenser side and the heat absorber side, and a working fluid sealed in the inner space and to undergo a liquid-vapor phase change by moving between the heat absorber side and the condenser side, to absorb heat from the printing medium to cool the printing medium that has passed through the fuser.
