Further, the data read from the digitizing memory 21 is written into a buffer memory 26 for storing printed characters and a blank print memory 30 for storing blank print status, depending on the purpose. Image memo! 727 is written with data that is not printed, such as guidelines that serve as a guide for typesetting. Therefore, the printed characters are transferred from the backup memory 26 to the display device 32.
Unprinted characters or data can be monitored on the display device 32 by writing the contents of the empty print memory 30 or image memory 27 to the refresh memory 28 and displaying it. . During typesetting work, when you want to check the overall layout, the entire layout is displayed in a reduced size on the display device 32, and when you want to make fine adjustments between each typed character, you can enlarge it and display and monitor it. The display magnification is changed quite frequently. Normally, in these processes, the contents of the memory are thinned out by hardware or displayed in duplicate, but when thinned out, the one-dot line guideline of the image memory 27 may disappear, and in this case, Processing such as rewriting using software is required every time the magnification is changed.

[Problem to be solved by the invention]

Since the monitor display device in the conventional phototypesetting apparatus is configured as described above, for example, when switching the display magnification to reduction to reduce the entire image and try to monitor the percentage on the display device 32, the information in the image memory 2T is As for data processing, if the data of one dot line is thinned out appropriately, it becomes K,
Every time the display magnification is changed, it is necessary to rewrite the contents of the image memory 27. This process poses problems such as a large amount of time required to switch the display magnification.

This invention was made to solve the above-mentioned problems.
It is an object of the present invention to provide a monitor display device for a phototypesetting device that can process data in a phototypesetting device at high speed.

[Means to solve the problem]

A monitor display device in a phototypesetting apparatus according to the present invention stores data that is necessary during typesetting work and is not printed in an image memory, and simultaneously stores data contents reduced based on a certain rule in the reduced image memory. Both types of data are switched and displayed according to commands from a writing and display control section.

[For production]

Corresponding to the image memory of the present invention, the reduced image memory that reduces and stores data based on a predetermined rule reduces the data at the same time as writing it to the original image memory according to a command from the display control unit to correspond to the writing display magnification. displayed on the display device.
