Abstract

PURPOSE:To decrease the number of times of using a variable power switch and to realize the labor saving by moving a zoom lens to a home position after having turned on a power source, and thereafter, moving it automatically to a set magnification which is stored in a memory. CONSTITUTION:When it is ended to initialize a control part being in the inside of a CPU by turning on a power source, whether a zoom lens exists in a home position determined by a structure of a zoom lens unit or not is checked, and when the zoom lens is in a position of other magnification, it is moved to the home position. Thereafter, by reading in the magnification which is set in advance, from a memory and moving the zoom lens to the set magnification, a machine is set to an operation possible state.

いる保証はできないという欠点がある。[Prior Art] In microreader printers with conventional zoom lens magnification mechanisms, some have a fixed magnification unique to the machine when the power is turned on, while others retain the magnification used last time. In the former case, if the magnification when the power is turned on is different from the frequently used magnification, the disadvantage is that the magnification must be changed every time the power is turned on. In addition, in the latter case, there is a possibility that the zoom lens may move during maintenance or become misaligned due to vibration, and there is a drawback that it cannot be guaranteed that the zoom lens will always maintain the magnification that was used last time. .

In a microreader printer that has a magnification change mechanism using a zoom lens, power is saved when setting the copying and projection magnification by performing zoom magnification control that automatically changes the magnification to a preset magnification when the power is turned on. This is what we are trying to achieve.

After it is moved to a fixed home position, it is automatically moved to a set magnification stored in memory.

ッチを使用する回数が減り省力化が図れる。[Function] As mentioned above, in order to set the copying and projection magnification of a microreader printer that has a variable magnification mechanism using a zoom lens, the zoom lens is automatically moved to the home position determined by the structure of the zoom lens unit after the power is turned on. After it is moved, it is automatically moved to the set magnification stored in memory, which ensures operational reliability and allows work to be started immediately, even if the magnification used is changed. Even if the zoom lens is in the opposite position, it can be moved to the desired position in a short time, reducing the number of times the magnification switch is used, resulting in labor savings.

After the zoom lens is moved to the home position determined by the structure of the zoom lens unit, the zoom lens is moved to the set magnification input to the memory, and the machine is ready for operation, so work can be started immediately. Since the user can immediately start moving to the desired position in a short time even if there is a difference in magnification, the number of times the magnification change switch is used is reduced, resulting in labor savings.
