Title: Recorder
Inventor: TANIOKA HIROSHI
IPC: B41J2/33
Filed: 1988-08-24
Abstract: PURPOSE:To stably record an image by providing energy applying means for ink to be fed by ink feeding means, transfer means to a medium to be recorded, and recording sensitivity detecting means. CONSTITUTION:When a record start signal is input to rotate an ink feeding roller 1 while rotating a coating roller 4, ink 2 is fed in a laminar state to the surface of the roller 1. In this case, the collector voltage of a transistor 15b3 is detected by a constant current from an electrode 15a to drive a water supply pump when it is a threshold value or more, thereby supplying water to the ink 2. Thus, a state that a sufficiently recording density is obtained is set, a recording sheet 8 is so conveyed until the end of the sheet 8 is moved to the position of a registration sensor 13, stopped, and a voltage responsive to a picture signal is applied to an ink layer on the roller 1 from an electrode element 5d. Then, adhesive is applied to the ink 2 of the conducted part to form an ink image 2a. In order to record, the resistance value of the ink 2 is maintained constantly by detecting means 15 and supplying means 16. Accordingly, a predetermined image density is always obtained.

Filed: 1998-07-24
Abstract: PROBLEM TO BE SOLVED: To form a stable image by maintaining the intensity of a laser beam constant during the exposing as well as preventing complicating of a temperature control circuit and lowering of the life of an element. SOLUTION: It is judged whether or not an initial temperature of a laser diode LD at a time before exposing is not higher than a reference temperature (S10, S12). When it is higher than the reference temperature, the exposing is started after the temperature of the LD is lowered to the reference temperature by a cooling operation (S14-S20). During the exposing, the driving current thereof is maintained at a predetermined level necessary for the output of the laser beam in a predetermined intensity and the LD is maintained at the reference temperature (S22). On the other hand, when the initial temperature is not higher than the reference temperature, the exposing is started in the initial temperature (S24).  At that time, the driving current which is necessary for the emission of the laser beam in the predetermined intensity emitted from the LD at the initial temperature, is maintained and the LD is maintained at the initial temperature.
