タ。[Claims for Utility Model Registration] 1. In a video printer that converts video information from analog to digital and stores it in memory for recording, the clock for storing video information must always start from a predetermined level, and the clock up to the first state change must be The time error is set to 1/1/2 of the above video information storage clock.
A video printer characterized in that the error is smaller than 4 cycles. 2 Utility model registration claim 1 in which the video information storage clock is started every time with a horizontal synchronization signal to reduce the error in the video information storage start position
Video printer as described in section. 3. The video printer according to claim 1, which is provided with means for selecting the frequency of a clock for transferring data from the memory to the thermal head, and which always starts the clock from a predetermined level. 4. A video printer using a plurality of clocks, which uses an oscillator with an oscillation frequency higher than the highest frequency among the frequencies of the clocks, and uses the oscillation frequency of this oscillator to generate a video information storage clock,
A video printer according to claim 1, which is a utility model that obtains at least two clocks selected from a clock for transferring data from a memory to a thermal head and a clock for driving a microcomputer.
