The present invention relates to a device for selecting a deformable lens in a photographic magnet.

As a deformed and enlarged lens selection device in a conventional photographic device, a deformed lens holder 8 in which a plurality of deformed lenses as shown in Japanese Utility Model Laid-Open No. 54-55826 is assembled, and a plurality of deformed lenses, respectively. And the enlarged lens holder 9 and the holder guide 7 installed on the body so as to be able to slide, respectively, and the gears each of the racks 15 and 16 provided in the lens holders 8 and 9 respectively. 18) (19) and at the same time. Display dials (23) and (31) for displaying the lenses accommodated in the lens holders (8) and (9) are provided on the front of the body. The display dial is rotated to engage the gear with the rack, and the lens holder is slid to position the desired lens on the optical axis, or as indicated in Japanese Utility Model Publication No. 58-42043. Likewise, the holder inserting portion (1) is inserted to insert the modified lens holder 18 rotatably fitted with the protective lens 16 directly behind the focus glass of the finder 8 of the photographic magnet. 22) and through the deformable lens 14, the deformed character image can be produced in the finder 8, so that the deformed lens 14 is turned with the fingertip to find the desired deformed object image. After the deformable lens holder 18 is extracted from the holder inserting portion 22 as it is, the deformed lens holder 18 provided directly under the photosensitive drum 11 is accommodated in the holder inserting portion 23 to perform printing. Is already configured to It is grounded.

A long obtained by assembling a plurality of deformable lenses having the same configuration as that described in Japanese Utility Model Publication No. 54-55826 in the holder 8, or a plurality of magnifying lenses in parallel with each other on the one line. Since the lens holders 8 and 9 need to be laterally moved in a straight line while reading the display of the display dials 23 and 31, a structural location is required, and the operator needs two display dials. In addition, it is necessary to carry out the residual care such as manipulating, and when using the same configuration as Japanese Utility Model Publication No. 58-42043, select the type of the deformable lens and insert it into the holder. In addition, the operator must make a lot of remnants, such as inserting it at a predetermined position on the feeding pipe line, and the present invention eliminates such defects and improves. It was done.

In view of the above, the present invention is configured to form a modified lens tarlet by leaving a single transparent window on a disc-shaped support plate which rotates about a tarret axis, and disposing a plurality of different lens barrels to be rotated, respectively. By rotating the let by the lens-setting pulse motor established on the frame side, it is possible to insert any deformable lens including the transparent window into the four-axis optical axis, and at the same time, such a lens barrel is sequentially inserted into each of the deformable lens barrels. Gears are installed to thermally interlock, and a deflection angle setting pulse motor is placed on the support plate to rotate each deformable lens barrel itself by the operation of the pulse motor. By operating the input unit, the expansion lens cylinder supporting plate is driven by driving the unfolding lens for lens setting. By rotating the lens to stop the desired deformable lens on the feeding optical axis, and similarly, by operating the Lenkey input unit, the deformable lens cylinder itself is driven with respect to the support plate. By rotating, by the action of a detector provided on the deformation lens barrel supporting plate, the deformation lens stopped on the optical axis can be set at a required angle.

When the modified lens is needed during the feeding, the operator drives the lens setting pulse motor by the key of the ten key input unit to rotate the pulse motor by rotating the modified lens tarlet and the action of the detector. The deformed lens of the lake is automatically placed at the insertion position on the optical axis for feeding, and at the same time, the pulse motor for setting the deformed angle is driven by the key operation of the ten-key input unit, and is actuated by the detector provided on the modified lens tarlet. As stated, the deformed lens barrel inserted on the optical axis can be rotated to the optical axis center so that it can be automatically set at a desired angle.
